Problems solved by technology

The shaft tube is a nearly rectangular structure, which is welded by a pair of U-shaped grooves. Although the front axle of this structure can solve the shortcomings of the forging method of the shaft body, the welding method of the shaft tube has an adverse effect on the fatigue strength of the shaft tube. Moreover, the cylindrical support of this scheme is fixed by welding or other methods. The welded part is located in the high-stress area of ​​the shaft body, so that the bending and torsional strength of the front bending position at the end of the shaft body is relatively weak, which affects The safety of the steering front axle

Embodiment Construction

[0018] like figure 1 Shown, as an embodiment of the present invention, the present invention provides a kind of automobile steering axle with support and steering function, and steering axle comprises axle body, steering knuckle and pivoting coupling (steering knuckle and pivoting coupling figure Not shown in, in the present invention, the pivotal coupling adopts the steering knuckle kingpin). The shaft body is composed of shaft end 1, shaft arm 2 and shaft center part 3. The shaft end 1, shaft arm 2 and shaft center part 3 are all hollow shaft tubes, and the suspended installation platform is in the area of ​​shaft center part 3. The shaft arm 2 connects the shaft end 1 and the shaft center part 3 at a certain angle, so that the shaft end 1 and the horizontal shaft center part 3 have a smoothly connected pipe section. The shaft body is a hollow structure, wherein the shaft end 1 and the shaft center part 3 have a rectangular cross-section, and the shaft arm 2 has a circular ...

Abstract

The invention relates to a steering axle of an automobile, comprising an shaft body, a steering joint and a connector, wherein, the connector is connected with the shaft body and the steering joint and enable the steering joint to pivot and rotate around the shaft body, the shaft body integrally comprises an shaft end, an shaft arm and an shaft center part, the shaft end, the shaft arm and the shaft center part are all hollow shaft tubes, a pivot rotation inserting block is arranged in the shaft end, and a containing hole of the connector penetrates through the upper wall face and the lower wall face of the shaft end and the pivot rotation inserting block. The steering axle of the automobile has the advantages of convenient processing and low manufacturing cost and can effectively enhance the mechanical properties of the rigidity, the bending-resistant and torsional strength and the like of an automobile axle.

Description

technical field [0001] The present invention relates to automobile axles, more specifically, to a steering axle capable of deflecting wheels at a certain angle. Background technique [0002] At present, cars driven by the rear axle are common in the automobile market. The steering front axle mainly includes shafts, steering knuckles and other components. The shafts are mostly forged. The suspension system is installed on the shaft body, so the upper surface plane of the I-beam is slightly wider than the lower surface plane or the upper surface plane of some parts in the middle is wider than the lower surface plane, so that the installation support platform of the suspension system is wide enough. A pair of cylindrical supports can be seen at the two ends of the steering front axle, which are obtained by boring the two ends of the shaft body after forging, and the king pin of the steering knuckle is installed in the hole. Pivot connection between. The processing cost of thi...
