Description

Technical Field

[0001] The utility model relates to the technical field of suspension assemblies, in particular to an automobile suspension assembly. Background Art

[0002] Suspension is the general term for all force-transmitting connection devices between the frame (or load-bearing body) and the axle (or wheel) of a car. Its function is to transmit the force and torque acting between the wheel and the frame, to cushion the impact force transmitted to the frame or body by the uneven road surface, and to reduce the vibration caused by it, so as to ensure that the car can run smoothly.

[0003] At present, the automobile suspension assembly on the market is composed of shock absorbers, suspension springs, guide mechanisms and corrugated dust covers and other components. Among them, the shock absorbers quickly attenuate the vibration of the automobile, the suspension springs support the vertical load, and alleviate and suppress the vibration and impact caused by uneven roads. The guide mechanism transmits force and torque and plays a guiding role. The corrugated dust cover is used to protect the shock absorber, suspension spring and guide mechanism from dust. However, since the automobile suspension assembly only has one section of suspension springs, and the elasticity of the suspension springs is fixed, the automobile often has an unfavorable tendency of "nodding" when braking, "raising the head" when accelerating, and serious left and right tilting due to the soft suspension springs, or the suspension springs are hard, resulting in low comfort. At the same time, when checking whether the corrugated dust cover is damaged, the car needs to be jacked up before inspection, which makes the corrugated dust cover more troublesome to check, and the driver cannot replace the damaged corrugated dust cover in time.
