What are SHOCK ABSORBERS (1)

Many people think that shock absorbers are used to support the weight of the car, but in fact, they mainly manage the movement of the suspension. Function Shock absorbers fulfill vital roles in a wide array of applications, particularly within mechanical and automotive frameworks. They are engineered to manage the forces of repulsion and impact associated with springs and suspension systems, thereby enhancing the overall stability and safety of vehicles. Working Principle Shock absorbers function on the basis of hydraulic principles, converting kinetic energy into thermal energy in order to regulate the movements of the suspension system.  They are comprised of a piston, which is connected to a piston rod, interacting with hydraulic fluid housed within a pressure tube. As the suspension system undergoes vertical motion, the hydraulic fluid is compelled to pass through minute openings, known as orifices, within the piston.  This process creates resistance, thereby decelerating the movement. The essence of this hydraulic resistance lies in its ability to dampen shocks and vibrations emanating from the road surface, thereby enhancing ride comfort.  Additionally, shock absorbers exhibit an adaptive characteristic, wherein the resistance they offer is contingent upon the speed of the suspension system. This adaptability allows for automatic adjustment to varying road conditions, ensuring optimal performance and stability across diverse terrains.

Shocks vs. Struts

ROLE OF SHOCKS AND STRUTS Quality ride control products perform many vital functions:   DIFFERENCE BETWEEN SHOCKS AND STRUTS Many times, you’ll hear people refer to shocks and struts interchangeably. However, shocks and struts are two distinct parts with different functions. While both can help with your vehicle’s ride and handling, these parts work in different ways. Shocks are individual components of the suspension system while struts are a major structural component of the chassis and suspension system. WHAT SHOCKS DO Despite what many people think, conventional shock absorbers do not support vehicle weight. Instead, the primary purpose of the shock absorber is to control spring and suspension movement. This is accomplished by turning the kinetic energy of suspension movement into thermal energy, or heat energy, to be dissipated through the hydraulic fluid. The amount of resistance a shock absorber develops depends on the speed of the suspension and the number and size of the tiny holes or orifices in the piston. All modern shock absorbers are velocity-sensitive hydraulic damping devices – meaning the faster the suspension moves, the more resistance the shock absorber provides. Because of this feature, shock absorbers adjust to varying road conditions and reduce the rate of: Shock absorbers work on the principle of fluid displacement on both the compression and extension cycle. A typical car or light truck will have more resistance during its extension cycle than its compression cycle. The compression cycle controls the motion of a vehicle’s unsprung weight, while extension controls the heavier sprung weight. SHOCK COMPONENTS Shock absorbers are basically oil pumps. A pistonis attached to the end of the piston rod and works against hydraulic fluid in the pressure tube. As the suspension travels up and down, the hydraulic fluid is forced through the orifices inside the piston. However, these orifices let only a small amount of

INTRODUCTION OF SHIMS (II)

Shimming When shimming, be sure to keep in mind the following best practices and risks to reduce the likelihood of equipment failure. Shim Design Considerations While shim rings and washershave the same appearance and some shims are even called washers, the two have very different functions — washers are designed to take and spread loads, while shims fill space.  Shims vs. Washers While both are used to protect machined components, reduce vibration, or act as a sound buffer, washers spread the load of a bolt or screw, and shims take up space and align parallel and angled surfaces of interfacing elements. Left: Washers are stamped, leaving a rollover edge and breakout edge. Washers cost less than shims.Right: Shims have smooth corners, flat edges, and parallel faces with flat, consistent thickness For best results, wall thickness for shims should be at least three times the material thickness. Preventing Wear If the hardness of the shim and component faces do not match, the softer face will be subjected to excessive wear. For best results, and to save time and money on rebuilds, shims should be designed into applications to prevent contact between expensive components. Measuring Space A set of feeler gauges (or leaf gauge) can be very handy to determine the amount of space that needs to be shimmed. Risks When a shim is used a small space is created above and below it. These spaces are compressed when a bolt is tightened or during the operation of a mechanical component. As shims are added, more compression takes place, increasing the risk of slippage or undesirable vibration of a mechanical component.  In addition to unwanted movement, additional spaces also increase opportunities of dirt and corrosion to develop. This can accelerate shim wear and cause premature failure.  Standard Shim Sizes Shim sizing is often proportional to the size of the anchor bolts. For motor frame applications, shim

INTRODUCTION OF SHIMS

Metal shimsare precisionmade shims from a variety of metals including carbon steel, alloy steel, spring steel, stainless steel, and brass. Metals shims are more durable and offer tighter tolerances than other types of shims. What Are Shims Used For? Shims are used for taking up excessive tolerances and gaps in assemblies like automotive body panels, electric motor mounts, and many other applications. In machining applications, shims are engineered to specific tolerances for use in precise machinery positioning. What are the Different Types of Shims? Different types of shims include arbor shims, variable shims, slotted shims, shim rings, and shim stock. While they are all used to take up excess tolerances, they each provide unique value to specific applications. Each type of shim has different designs and features to make them suitable for different applications.   Arbor Shims Common Names: Shim, Slitter Shim, Shim Washer. Applicable Standards: None known. Fabrication: Most commonly made from high carbon steel, also known as blue tempered, stainless steel, or brass. Other materials not standard, but are used. Common Uses: Used for fast, accurate spacing of milling cutters, gang cutters, saws, slitting blades, and grinding tools. Comments: Some versions made from 1010 full hard material, which is more pliable but has less wear properties than blue tempered.  Arbor shims (slitter shims) are thin, washer likediscsdesigned to prevent axial movement in assembled components. Arbor shims are machined to specific tolerances for an exact fit and used in machinery alignment applications on milling cutters, saws, and grinding tools. How Are Arbor Shims Measured? Arbor shims are measured by their thickness, outer diameter, and inner diameter. When ordering, arbor shims are identified by their inner diameter and thickness. It is important to know that there are arbor shims and spacers, and they are different fasteners. Arbor spacers feature a keyway that allows it to slide over a keyed shaft, which is a characteristic required for use on milling machines, slitting saws, and

Application of Coilover

Coilover has soft and hard, high and low, adjustable damping and other functions, can be adjusted according to personal needs, in a certain range of personal satisfaction with the setting. It originated from racing cars. In order to adapt to various tracks, the setting of springs and shock absorbers needs to be changed, which is too troublesome and will increase the cost. Coilover can solve these problems, greatly changing the handling performance of vehicles without the need to replacesprings and shock absorbers.  The replacement of the coilover belongs to the professional transformation, which has a high degree of freedom for the vehicle setting. If you want to debug the skein shock absorber, you need to repeatedly test and experience, and finally achieve the effect that the owner wants. Even if it is the same model to replace the same product, there will be differences, and individuals also have very subjective feelings about the demand for control.   The biggest feature of coilover is the adjustable height (high-end products also have adjustable multi-path damping design), we first look at the impact of the height of the body. When the vehicle is stationary, the distance from the ground of the four corners of the chassis has a great impact on the wheel load on the position. For example, the left front wheel suspension rises, increasing the load on the right rear wheel on the diagonal, while the load on the two wheels on the diagonal will be reduced.  Therefore change chassis height can control the vehicle before and after the counterweight, of course, the adjustment of the counterweight is limited scope. For adjustable shock absorbers(compression and rebound damping can be adjusted), the method of adjustment is more complicated. More advanced shock absorbers also have adjustable damping designs for high and low speeds. Taking the compression damping setting as an

Motorcycle Shock Absorber

Motorcycle shock absorber is an important part of the motorcycle, and the correct daily maintenance of the shock absorber can extend the service life of the shock absorber. This article will introduce the function and structure of the shock absorber, daily maintenance and other aspects, in order to deepen the user’s understanding of the shock absorber, and better use and maintenance of the shock absorber. The front shock absorberconnects the frame and the front wheel together flexibly, and uses the buffer spring and damping mechanism to effectively cushion the impact from the ground. The excellent shock absorption system can keep the vehicle stable, ensure the operation comfort, and bring a pleasant riding experience to the driver. The front shock absorber is mainly composed of fork rod, bottom cylinder, buffer spring, piston rod, oil seal, dust cover and other parts, and the damping oil is sealed inside.When the shock absorber spring is compressed, the damping oil flows through the free valve and the return oil hole. When the spring springs back, the free valve is closed, and the damping oil only flows through the damping hole, thus playing the role of inhibiting the spring rebound. The damping spring and damping system cooperate well to play the role of damping and buffering. The role of the rear shock absorber is used to support the weight of the frame, ease the vibration and impact of the uneven road on the motorcycle, and rapidly attenuate the vibration, improve the riding comfort, reduce the dynamic stress of each part of the body, and extend the service life of the vehicle.Structural features At present, a large number of spring hydraulic shock absorbers are used on motorcycles. It is mainly composed of spring and hydraulic damper two parts. The piston of the hydraulic damper is provided with several damping through holes,

What is the coilover suspension?

The coilover is an automobile suspension device. The name coilover is an abbreviation of “coil over shock absorber“. A coilover suspension (also called a screw suspension) refers to a suspension that allows individual adjustment of the ground clearance. This is done by means of a screw thread on the suspension strut. For this reason, a car with a coilover suspension can also be raised or lowered quickly and without tools by private individuals. Why we need a coilover suspension? Firstly, a coilover suspension is an exceptional system that combines both the spring and shock absorber into one unit known as a coilover. This ingenious design offers enhanced stability and comfort during your driving experience. Imagine yourself cruising along a road filled with potholes; without a reliable suspension system, your car would be subjected to constant rocking and shaking. However, with the implementation of a coilover suspension, it effectively absorbs all those bumps, ensuring a more comfortable ride. Furthermore, one notable advantage of the coilover suspension is its ability to adjust the height of your vehicle. Whether you desire a lower or higher stance for your car, simply modify the coilovers accordingly. This feature allows for customization based on personal preferences and requirements regarding both aesthetics and performance. In summary, opting for a coilover suspension guarantees not only improved stability and driving comfort but also grants you control over adjusting your vehicle’s height according to individual preferences. If optimal performance coupled with unparalleled comfort is what you seek in your car, then choosing a coilover suspension is undoubtedly the right decision! Who needs a coilover suspension? A coilover suspension is installed when you want to lower your car and/or achieve sportier handling. In addition to flexible lowering, most coilover suspensions also have other adjustment options. In addition to the hardness, the driver can often also adjust the
