Suspension device for car

Abstract

The present invention provides a vehicle suspension where bump stoppers are installed in an upper end of a strut and on an upper end of a lower arm respectively so that the bump stoppers can operate separately or simultaneously, depending on the size of a load, to absorb or reduce vibration or shocks. The vehicle suspension consists of an upper arm assembly being connected to an upper portion of a drive shaft assembly where wheels are connected; a lower arm assembly being connected to a lower bracket of said drive shaft assembly, and including a bump stopper at an upper surface which starts contacting a chassis frame's stopper bracket if a load from a road surface is the same as or more than a preset base load; a shock absorber, at it's a lower portion, being attached to said lower arm assembly, and including a main spring located on an outer surface, a strut assembly with a striking plate, an upper mount attached to a vehicle body and other bump stopper in an upper face which starts contacting the striking plate if a load from the road surface is the same as or less than said preset base load; and a stabilizer, at it's an end being connected to the lower arm assembly.

Description

field of invention [0001] The present invention relates to automobile suspensions. More specifically, the present invention is an automotive suspension having: a bump stop located on the upper end of the strut of the shock absorber; and another bump stop located on the upper end of the lower arm, Depending on the size of the load, the two impact stops can work independently or simultaneously to absorb or dampen vibrations or shocks. Background technique [0002] Typically, in an automobile such as a passenger car, the suspension connects the axle and the body of the automobile. It is designed to prevent vibrations or shocks from the road surface from being transmitted to the car body, thereby improving passenger comfort and keeping the transport stable. This type of suspension includes: chassis springs, which absorb vibrations from the road; shock absorbers, which improve ride comfort by controlling the free vibrations of the chassis springs; and stabilizers, which prevent...

AI Technical Summary

Problems solved by technology

[0005] Furthermore, in the case of impact stops mounted in shock absorbers or lower arms, the exact timing of contact between the stopper and a suitable object cannot be set according to the various sizes of axial loads from the road

[0006] If the initial spring constant of the slam stopper is reduced to be the same as that of the main spring or half of the main spring, the bottom vibration phenomenon is reduced, but the durability of the slam stopper is reduced, making it easy to break or damage
