Embodiment Construction

[0019] In order to make the structure and function of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0020] see Figure 1 to Figure 4 As shown, the taper of the main pin installation taper hole 1 is 1:10, the major diameter is 31.9 mm, and the minor diameter is 28.9 mm. The kingpin is 11.5° to the normal plane of the semi-axis, that is, the kingpin inclination is 11°, the wheel camber is 0.5°, and the kingpin caster is 3°. This can well ensure the smoothness of driving, handling stability and tire return performance. figure 1 It only shows that the sum of the kingpin inclination and the wheel camber is 11.5°, and the kingpin caster can only be reflected in the overall structure when it is assembled with the upper and lower cross arms, so figure 1 Not marked in.

[0021] see figure 2 As shown, the brake mounting seats 3 and 4 are formed by extending the steering knuckle body towa...

Abstract

The invention provides a steering knuckle component used for an independent suspension system. A steering knuckle body extends towards the same side to form brake installation bases used for avoiding a main pin hole. The steering knuckle can be provided with an oil brake of the corresponding tonnage. Front wheel positioning parameters are set on the steering knuckle, and the driving stability, handling stability and tire returning performance of an automobile can be well ensured. A lightweight design concept is added to the steering knuckle, and the steering knuckle component is simple in structure and convenient to machine. The steering knuckle is applicable to a 2.8 T independent suspension front axle.

Description

technical field [0001] The invention relates to an automobile steering mechanism, in particular to a steering knuckle component used in an independent suspension system. Background technique [0002] With the continuous development of independent suspension of automobiles, independent suspensions are constantly used from sedans to medium-sized buses to large buses, and independent suspensions have greatly improved the comfort of passenger cars. However, the most critical safety component in the independent suspension is the steering knuckle, and the steering knuckle also has a variety of structures according to different suspension performance requirements. [0003] The independent suspension knuckle components are essentially different from the non-independent suspension knuckle components. The independent suspension knuckle components are mainly connected to the upper and lower cross arms respectively, while the non-independent suspension knuckle components are connected t...
