Description

Technical Field

[0001] The present invention belongs to the technical field of suspension production, and particularly relates to a tooling table for an H-arm suspension. Background Art

[0002] With the rapid development of new energy vehicles, especially the popularization of electric four-wheel drive models, the requirements for suspension systems are increasing day by day. The H-arm suspension, with its unique structural design, can effectively optimize the weight distribution of electric vehicles, improve space utilization, enhance handling performance and comfort. Therefore, the H-arm suspension has become an important choice in the suspension system of electric vehicles. However, the design of the H-arm suspension also faces some challenges. Especially in the case of a compact vehicle layout, it usually leads to the inability to effectively adjust the wheel camber angle, failing to meet the design requirements of four-wheel alignment.

[0003] Currently, the commonly adopted solution in the industry is to improve manufacturing accuracy through the assembly dimension chain, thereby controlling the wheel camber angle. This method controls the assembly dimensions of each component in the suspension system to ensure that the wheel camber angle meets the design requirements. Specifically, the dimension chain consists of a series of dimensional tolerances that need to be precisely controlled, and the precise assembly of the suspension system is ensured through reasonable design and precise production processes. However, although the dimension chain method can improve the accuracy of the wheel camber angle, it still has problems such as complex control and difficult adjustment in practical applications. During the production process, minor deviations in dimensions may result in inaccurate adjustment of the wheel camber angle, thus affecting the four-wheel alignment of the whole vehicle, reducing the handling stability and driving safety of the vehicle. In addition, since this process relies on highly precise manufacturing processes, it increases production costs and is accompanied by a high failure rate, directly affecting the production rhythm and overall production efficiency.

[0004] In view of this, overcoming the above-mentioned defects of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

The lower surface of one side of the first floor panel 101 in the second direction is attached to the upper surface of the second floor panel 102 to form a sliding connection;

[0050] Exemplarily, a plurality of mounting holes extending in the second direction are provided on the upper surface of the second floor panel 102. A plurality of studs are connected to the lower surface of the first floor panel 101 corresponding to the plurality of mounting holes. The plurality of studs penetrate the plurality of mounting holes one by one, and the plurality of studs are detachably connected to the first floor panel 101 through a plurality of nuts; similarly, the third floor panel 103 and the first floor panel 101 are also detachably connected through a plurality of mounting holes, a plurality of studs, and a plurality of nuts.

[0051] In the present invention, the floor panel 1 is integrally divided into a first floor panel 101, a second floor panel 102, and a third floor panel 103, and the processing of the large panel is changed to the processing of small panels, which improves the efficiency of the processing and production process of the floor panel 1; and on the basis that the relative positions of the first floor panel 101, the second floor panel 102, and the third floor panel 103 can be changed, the operation requirements for carrying different specifications of suspensions are met.

[0052] Correspondingly, the two steering knuckle support brackets 8 and the two clamping assemblies 5 are respectively arranged on the surfaces of the second floor panel 102 and the third floor panel 103.

[0053] At the same time, the side arm bracket 6 includes a first side bracket 601 and a second side bracket 602, and is used to carry the head and tail ends of the left H-arm assembly 2' or the right H-arm assembly 3' of the suspension; in Figure 5 the example shown, the first side brackets 601 of the two side arm brackets 6 are all arranged on the first floor panel 101, the second side bracket 602 of one of the side arm brackets 6 is arranged on the second floor panel 102, and the second side bracket 602 of the other side arm bracket 6 is arranged on the third floor panel 103.

[0055] At the same time, it also includes a knuckle support frame 8. The two knuckle support frames 8 are respectively located on the second bottom plate 102 and the third bottom plate 103. In Figure 3 the illustrated example, the first side frame 601 and the second side frame 602 are coaxially arranged in the second direction, and the knuckle support frame 8 and the second side frame 602 on the same side are coaxially arranged in the first direction, so that the knuckle support frame 8 and the first side frame 601 and the second side frame 602 on the same side together form a right triangle arrangement form.

[0056] Correspondingly, a first rubber pad 9 is installed at the output end of the front support frame 2. The cross section of the first rubber pad 9 adopts an M-shaped structure, so that the bearing surface of the first rubber pad 9 extends along the first direction; a second rubber pad 10 is installed at the output end of the rear support frame 3. The cross section of the second rubber pad 10 adopts a U-shaped structure, so that the bearing surface of the second rubber pad 10 extends along the second direction, and the axis lines of the bearing surfaces of the first rubber pad 9 and the second rubber pad 10 are perpendicularly arranged.

[0057] Reference Figure 1 and Figure 6 , the docking end pipe 105' of the rear subframe assembly 1' is carried by the first rubber pad 9, and the rear cross beam 102' of the rear subframe assembly 1' is carried by the second rubber pad 10, so as to support the rear subframe assembly 1' from two directions. While giving the suspension an upward vertical supporting force, the stability of the suspension placement is further improved, and the supporting force when the suspension tilts forward and backward and left and right is given.

One side of the horizontal part is connected to the output end of the knuckle support frame 8, and the other side of the horizontal part is connected to two symmetrically arranged vertical parts. The two vertical parts and the horizontal part together form a receiving groove for carrying the knuckle assembly.

[0059] Reference Figure 4 , on the basis of the second bottom plate 102 and the third bottom plate 103 detachably connected to the first bottom plate 101, first weight-reducing grooves 12, second weight-reducing grooves 13 and third weight-reducing grooves 14 are provided on both sides of the first bottom plate 101.

[0063] The bottom plate 1 of the present application reduces its own weight by opening the first weight reduction groove 12, the second weight reduction groove 13, the third weight reduction groove 14 and the fourth weight reduction groove 15. While reducing the production cost, it changes its own gravity distribution, corresponding to the basic property of the suspension being heavier in the front and tilted backward, thereby improving the stability of the suspension placed on the tooling table to avoid the problem of the suspension tilting forward and backward.
