Front suspension assembly

Abstract

The invention provides a front suspension assembly, which comprises a front suspension upper plate, a mounting stud, a positioning pin, a front suspension lower plate, a rubber main spring and a limiting stud, and is characterized in that the front suspension upper plate is arranged on the top surface of the rubber main spring, and the front suspension lower plate is arranged on the bottom surface of the rubber main spring; the positioning pin and the mounting stud are respectively arranged on the front suspension upper plate; a first accommodating hole for accommodating a limiting head of the positioning pin and a second accommodating hole for accommodating a limiting head of the mounting stud are formed in the rubber main spring; the limiting stud sequentially penetrates through the front suspension lower plate and the rubber main spring from bottom to top and then is connected with a limiting head of the mounting stud, the limiting stud and the mounting stud are coaxial, and the limiting head of the limiting stud is located below the front suspension lower plate. The rubber main spring can be well limited in all directions, the service life of the rubber main spring is prolonged, meanwhile, space can be saved, and comfort of an automobile is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension systems, and in particular relates to a front suspension assembly. Background technique [0002] In modern powertrain longitudinally mounted models, the mount system is required to have the functions of vibration isolation and control of powertrain displacement. Generally, a three-point mount arrangement with two front and one rear or a four-point mount arrangement with two front and two rear is adopted. The suspension installed on the engine side is called the front suspension assembly, and generally adopts a V-shaped left-right symmetrical layout structure with a certain inclination angle, such as figure 1 As shown, the front and rear mounts should have limit structures in all directions to ensure uniform stress on each mount and effectively limit the displacement of the powertrain. Wherein, the vehicle body side mounting bracket 13 is stationary relative to the vehicle body; the ...

Problems solved by technology

[0006] 1. The front suspension assembly is in the W positive unlimited position structure. When the powertrain jumps up, in order to limit the movement of the powertrain within the required space, it is necessary to increase the stiffness of the front suspension, resulting in increased vibration and noise in the car. large, poor comfort

[0007] 2. The positive direction of the front suspension assembly W is the stretching direction of the rubber and has an infinite structure. The durability of the rubber in the stretching direction is poor, which causes the rubber to age and break easily, and the consistency of the vulcanization process is also likely to cause the main body of the rubber to break. Fracture or disengagement of the vulcanized layer, if the above situation occurs, the front suspension assembly cannot support and limit the power assembly, resulting in the failure of the suspension system structure and causing safety accidents

[0008] 3. Since the cushion cover is assembled on the outside of the suspension cushion as a limit device and moves with the engine, it must be ensured that it does not interfere with other components on the movement path, which takes up a lot of space, resulting in insufficient space for other components , it is more difficult to arrange
