Upper mounting seat

Abstract

The invention discloses an upper mounting seat which includes a rubber bushing, a rigid frame, and a rigid cover. The upper end surface of a McPherson suspension damping spring abuts against a connecting plate on the outer periphery of a rigid frame, excitation from the road surface is transmitted to the rigid frame through a spring, and then transmitted to a vehicle body through the rigid frame.A shock absorber transmits force received by the shock absorber to the vehicle body through the rubber rod through a piston rod, that is to say, the rubber bushing transfers the damping force from theshock absorber, and the rigid frame transfers the spring force from the shock absorber spring to realize the dual channel transfer of damping force and spring force. After the spring passes through the rigid frame, the force received by the spring is directly transmitted to the vehicle body, and the damper transmits the force received by the damper to the vehicle body through the piston rod, andthe excitation from the road surface is mainly transmitted to the vehicle body through the spring, the lateral force on the piston rod of the damper is relatively small, so that the handling and comfort of the vehicle are optimized at the same time.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an upper mount. Background technique [0002] McPherson suspension is the most used front suspension structure in the 5-7 seat family cars on the market. Due to the particularity of the suspension structure, the spring + damper with integrated force transmission and vibration damping functions is usually used. The shock absorber integrated pillar structure is responsible for transmitting the interaction force between the wheel and the vehicle body. In order to alleviate the impact load between the tire and the ground and transmit it directly to the body, the upper end of the one-piece strut structure will have a rubber top mount. The traditional overhead support structure includes connected upper and lower grooves, and the spring and shock absorber of the MacPherson suspension are directly in contact with the overhead support from the lower groove, and the overh...

AI Technical Summary

Problems solved by technology

The traditional overhead support structure includes connected upper and lower grooves, and the spring and shock absorber of the MacPherson suspension are directly in contact with the overhead support from the lower groove, and the overhead support is affected by the spring force of the MacPherson suspension and The force of the shock absorber is directly transmitted to the body through a force transmission path, the force transmission path is single, and there is mutual interference between the shock absorber force and the spring force

[0003] The upper mounting seat should not only play the role of handling, but also take the role of comfort. After improving the handling, the comfort will inevitably decrease, and it is impossible to achieve the optimal handling and comfort of the vehicle at the same time.
