A steering knuckle connector assembly suitable for linear translation front suspension

Abstract

Provided is a steering knuckle connector assembly applicable in a linear translation-type front suspension, primarily comprising a steering knuckle body (7), an upper ball joint stud (5) and a lower ball joint stud (9), an upper end base (8) and a lower end base (4) connected to a suspension branch chain, and a reinforcing element (3). The upper end base (8) and the lower end base (4) are fixedly connected via the reinforcing element (3). A through hole is provided on the reinforcing element (3) and used for arranging therethrough a drive shaft (103). Provided on the steering knuckle (7) are a brake mounting hole (6) assembled with a brake (105), a steering rod mounting hole (2) assembled with a steering rod (104), a wheel hub bearing unit assembling hole (11) assembled with a wheel hub unit, a lower end ball joint mounting hole (12) assembled with the lower ball joint stud (9), and an upper end ball joint mounting hole (13) assembled with the upper ball joint stud (5). A shock absorber mounting base (1) used for assembling a spring shock absorber (101) is fixedly connected at a middle position of the upper end base (8). The upper ball joint stud (5) is mounted on the upper end base (8). The lower ball joint stud (9) is mounted on the lower end base (4). The axes of the upper ball joint stud (5) and of the lower ball joint stud (9) form a king pin axis (10) used for implementing steering. The upper end base (8) is also provided with an upper end first lug (14) and an upper end second lug (17). The lower end base (4) is provided with a lower end first lug (15) and a lower end second lug (16). The upper end first lug (14), the upper end second lug (17), the lower end first lug (15), and the lower end second lug (16) are each provided with a suspension branch chain connecting hole for connecting a suspension guiding mechanism (102). A vehicle using the steering knuckle connector assembly and the linear translation-type suspension mechanism allows a wheel alignment parameter to be kept unchanged at all times while wheels are vibrating up and down, thus effectively reducing wearing of tires, effectively implements a steering function of the wheels, and, by adjusting the mounting positions of the ball joints, allows the attitude angle of the steering king pin axis to be adjusted, which allows flexible arrangement of the suspension, thus facilitating improved vehicle handling stability, travel smoothness, and ride comfort.

Description

Technical field [0001] The invention relates to the field of steering knuckles of automobile front suspension systems, and more specifically, to a steering knuckle connecting piece assembly suitable for linear translational front suspensions. Background technique [0002] At present, the suspensions of passenger cars in the market, especially middle and high-end cars, mostly adopt multi-link independent suspension. The steering knuckle used in conjunction is one of the key components in the suspension structure, and its main function is to connect the multi-links. Each guide rod branch chain, shock absorber, brake caliper and wheel hub bearing of independent suspension. [0003] Although independent suspensions such as conventional multi-link suspensions are functionally capable of meeting the suspension design requirements, the wheel alignment parameters will change when the wheels bounce. How to ensure that the positioning parameters of the wheels will not change when the wheels...

Problems solved by technology

However, the steering knuckle mentioned above does not have a steering function and is not suitable for the front suspension system; in addition, the steering knuckles commonly used in the market cannot match the new linear translation suspension, and the suspension cannot be realized. The smooth connection between each branch chain of the mechanism and the hub unit
