A Breakaway Rigid Kingpin Structure Applied to Independent Suspension

Abstract

The invention belongs to the technical field of automobile suspension, and discloses a disconnected rigid kingpin structure applied to an independent suspension, comprising a mounting seat, a steering knuckle is movably mounted on the right side of the mounting seat, and the top end of the steering knuckle is movably mounted. The inside of the steering knuckle is provided with an upper pin hole of the steering knuckle, the bottom end of the steering knuckle is provided with a lower pin hole of the steering knuckle, and the inner movable sleeve of the upper pin hole of the steering knuckle is connected with the upper king pin. In the present invention, the upper pin hole of the steering knuckle, the lower pin hole of the steering knuckle, the lower king pin shaft, the lower king pin and the mounting interface of the shock absorber are arranged. Due to the coaxial design of the upper pin hole of the steering knuckle and the lower pin hole of the steering knuckle, the The subsequent installation of the upper swing arm assembly and the lower swing arm assembly is realized respectively, and the steering function is realized on the large-tonnage independent suspension. Due to the cooperation between the lower king pin and the shock absorber installation interface, it can inherit the Drive systems such as shock absorbers and motors are installed to reduce the space occupied by the wheel.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension, in particular to a disconnected rigid kingpin structure applied to an independent suspension. Background technique [0002] Automobile suspension is an important component to ensure ride comfort. At the same time, automobile suspension is a force-transmitting part connecting the frame and the axle, and it is also an important component to ensure the safety of automobiles. Therefore, automobile suspension is often listed as a Important parts are incorporated into the technical specification sheet of the car as one of the indicators to measure the quality of the car. [0003] At present, there are two main structural forms of the kingpin applied to the independent suspension. One is the rigid kingpin structure. Generally, the steering knuckle is installed on the airbag arm through a rigid kingpin. The airbag arm is connected to the upper swing arm and the upper swing arm through two p...

Problems solved by technology

[0003] At present, the kingpin used in the independent suspension mainly has two structural forms, one is the rigid kingpin structure, the general steering knuckle is installed on the airbag arm through a rigid kingpin, and the airbag arm is connected with the upper swing arm and the upper swing arm through two pin shafts. The lower swing arm is connected, and the airbag is installed on the airbag arm. The main defect of this structure is that the position of the kingpin occupies a large space around the wheel, and there is no space for integrating the drive system such as the reducer and the motor. The other structure is a virtual kingpin The structure is that by setting a ball joint on the upper swing arm and the lower swing arm, the upper end and the lower end of the steering knuckle are respectively connected with the ball joint, and the steering knuckle can rotate around the line connecting the upper and lower ball points to realize steering. When moving, the steering knuckle and the upper and lower swing arms can also move relative to each other. The main defect of this structure is that the load-bearing capacity is weak, and the elastic elements can only be installed on the long lower swing arm, and the occupied space cannot inherit the drive system such as the reducer and the motor. , if the space occupied by the elastic element is released, the elastic element can only be arranged on the upper swing arm, then the length of the upper swing arm should be made longer, which will affect the channel width between the left and right upper swing arms, so it is necessary to its improvement
