Products knowledge

The shock absorber assembly is composed of shock absorber, lower spring pad, dust cover, spring, shock pad, upper spring pad, spring seat, bearing, top rubber and nut.

The shock absorber assembly uses fluid to convert the elastic energy of the spring into thermal energy to optimize the convergence of vehicle motion, thereby eliminating the vibration caused by the road surface, improving driving stability, and giving the driver a sense of comfort and stability.

The shock absorber assembly is composed of shock absorber, lower spring pad, dust cover, spring, shock pad, upper spring pad, spring seat, bearing, top rubber, and nut

The total components of the shock absorber are four parts: front left, front right, rear left and rear right. The position of the lugs (claw connecting the brake disc) at the bottom of the shock absorber in each part is different, so when choosing a shock absorber When assembling, be sure to identify which part of the shock absorber assembly is. Most of the front shock absorbers on the market are shock absorber assemblies, and the rear shock absorbers are still ordinary shock absorbers.

Difference from shock absorber

different structure

The difference between shock absorber assembly and shock absorber

The shock absorber is only a part of the shock absorber assembly; the shock absorber assembly consists of a shock absorber, a lower spring pad, a dust jacket, a spring, a shock absorber pad, an upper spring pad, a spring seat, a bearing, a top rubber, and a nut .

2. The difficulty of replacement is different

Replacing an independent shock absorber is difficult to operate, requires professional equipment and technicians, and has a high risk factor; replacing the shock absorber assembly only requires a few screws to be done easily.

3. Price difference

It is expensive to replace each part of the shock absorber package separately; the shock absorber assembly includes all the parts of the shock absorber system, and the price is cheaper than replacing all the parts of the shock absorber.

4. Different functions

A separate shock absorber only acts as a shock absorber; the shock absorber assembly also plays the role of a suspension strut in the suspension system.

working principle

The shock absorber assembly is mainly used to suppress the shock when the spring rebounds after shock absorption and the impact from the road surface, and is used to counteract the torsional vibration of the crankshaft (that is, the phenomenon that the crankshaft is twisted by the impact force of the cylinder ignition).

In the suspension system, the elastic element vibrates due to the impact. In order to improve the ride comfort of the car, a shock absorber is installed in parallel with the elastic element in the suspension. In order to dampen the vibration, a hydraulic shock absorber is generally used in the shock absorption system. When there is relative movement between the frame (or body) and the axle due to vibration, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity to another through different pores. Inside.

The structure of the shock absorber is that the piston rod with the piston is inserted into the cylinder, and the cylinder is filled with oil. There are orifices on the piston, so that the oil in the two parts of the space separated by the piston can complement each other. Damping is generated when the viscous oil passes through the orifice. The smaller the orifice, the greater the damping force, and the greater the viscosity of the oil, the greater the damping force. If the size of the orifice remains unchanged, when the shock absorber works at a high speed, excessive damping will affect the absorption of shock. [1]

The shock absorber and the elastic element undertake the task of buffering and shock absorption. If the damping force is too large, the elasticity of the suspension will be deteriorated, and even the shock absorber connection will be damaged. Therefore, it is necessary to adjust the contradiction between the elastic element and the shock absorber.

(1) During the compression stroke (the axle and the frame are close to each other), the damping force of the shock absorber is small, so that the elastic effect of the elastic element can be fully exerted to ease the impact. At this time, the elastic element plays a major role.

(2) During the extension stroke of the suspension (the axle and the frame are far away from each other), the damping force of the shock absorber should be large, and the shock absorber should be quickly damped.

(3) When the relative speed between the axle (or wheel) and the axle is too large, the shock absorber is required to automatically increase the fluid flow, so that the damping force is always kept within a certain limit to avoid excessive impact load.

Product action

The shock absorber assembly uses the fluid to convert the elastic energy of the spring into thermal energy, so as to optimize the convergence of vehicle motion, thereby eliminating the vibration caused by the road surface, improving the driving stability, and giving the driver a sense of comfort and stability.

1. Suppress the vibration transmitted to the body during driving to improve ride comfort

Buffers shocks delivered to the driver and passengers to improve ride comfort and reduce fatigue; protect loaded cargo; extend body life and prevent spring damage.

2. Suppress the rapid vibration of the wheels when driving, prevent the tires from leaving the road, and improve the driving stability

Improve driving stability and adjustability, effectively transmit the deflagration pressure of the engine to the ground, so as to save fuel costs, improve braking effect, prolong the life of various parts of the car body, and save the maintenance cost of the car.

Troubleshooting method

The shock absorber assembly is a vulnerable part during the use of the car. The oil leakage and rubber damage of the shock absorber will directly affect the stability of the car and the life of other parts. Therefore, we should keep the shock absorber in good condition. working status. Shock absorbers can be inspected in the following ways:

Stop the car after driving 10km on a road with poor road conditions, and touch the shock absorber shell with your hand. If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber does not work. If the housing is hot, there is a lack of oil inside the shock absorber. In both cases, the shock absorber should be replaced with a new one immediately.

Press the bumper hard, then release, if the car jumps 2~3 times, the shock absorber is working well.

When the car runs slowly and brakes urgently, if the car vibrates violently, it means that there is a problem with the shock absorber.

Remove the shock absorber and stand it upright, and clamp the lower end connecting ring on the vise, and pull and press the shock absorber rod several times. At this time, there should be a stable resistance. If the resistance is unstable or there is no resistance, it may be due to lack of oil inside the shock absorber or damage to the valve parts, which should be repaired or replaced.
