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 31.9mm, and the minor diameter is 28.9mm. 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 toward...

Abstract

The invention provides a knuckle for independent suspension systems, which comprises brake-mounting seats, and the brake-mounting seats stretch toward the same side from the knuckle body to keep away from a main pin hole. The knuckle can be equipped with an oil brake of corresponding tonnage. All front wheel alignment parameters are set on the knuckle, and the running stability, control stability and tyre returnability of an automobile can be perfectly ensured. A lightweight design concept is also added into the knuckle, moreover, the structure is simple, and the knuckle is convenient to machine. The knuckle is applicable to 2.8 T independent suspension front axles.

Description

technical field [0001] The invention relates to an automobile steering mechanism, in particular to a steering knuckle for 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] There is an essential difference between the independent suspension knuckle and the non-independent suspension knuckle. The independent suspension knuckle is mainly connected to the upper and lower cross arms respectively, while the non-independent suspension knuckle is connected to the axle through a kingpin. Attached to the...
