Problems solved by technology
The bridge tube is an approximately 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 bridge body, the welding method of the bridge tube has an adverse effect on the fatigue strength of the bridge tube. Moreover, the columnar support of this scheme is fixed by welding or other methods, and the welded part is located in the high-stress area of the bridge body, so that the bending and torsional strength of the front bending position at the end of the bridge body is relatively weak, affecting The safety of the steering front axle

Embodiment Construction
[0028] Such as Figure 1-5 As shown, the present invention provides an integrated front axle structure with support and steering functions, which includes an axle body, a steering knuckle and a pivoting kingpin. The bridge body is composed of the bridge end 1, the bridge arm 2 and the bridge center part 3. The billet tube of the integral front bridge structure is a hollow seamless steel pipe. The extruded pier in the mold is a solid end, and the temperature parameters of different parts of the end of the billet tube are controlled during the extrusion process, so that the section A of the pipe connecting the bridge arm from the solid end forms a region with a gradually smaller wall thickness , wherein the length of the pipe section A is about 45-80mm, and the optimum length is 60mm. Bridge pipe middle part 3 pushes square and becomes rectangle, and bridge pipe middle part 3 both sides are bridge arm 2, and the cross section of bridge arm section may be circular, (also can be ...

The invention relates to an integral front-axle structure which comprises an axle body, a steering knuckle and a king pin by which the axle body and the steering knuckle can be connected and the steering knuckle can be pivoted around the front axle, wherein the axle body is prepared by integrally processing tube blanks and comprises an axle end, an axle arm and an axle center part, the axle arm and the axle center part are hollow axle tubes, the axle end is a solid end formed by extruding the tube blanks, and the axle end is provided with a steering knuckle pin hole. The integral front-axle structure provided by the invention has the advantage of low manufacturing cost, is convenient to process, and can effectively enhance the mechanical properties such as rigidity, bending strength, torsional strength and the like of an axle.
Description
technical field [0001] The invention relates to the technical field of automobile axles, and more specifically relates to an integral front axle structure. Background technique [0002] At present, cars driven by the rear axle are common in the automobile market. The front axle to which it turns mainly includes the bridge body, steering knuckle and other components. The bridge body is mostly forged. The suspension system is installed on the beam bridge 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 holes at both ends of the bridge body after forging, and the steering knuckle kingpin is installed in the hole. Pivot connection between. The p...
