Embodiment 1

[0033] Please combine Figure 1 to Figure 4 , the car rear axle bracket includes a cross arm 1 and a longitudinal arm 2 vertically arranged with the cross arm 1. The interior of the cross arm 1 is hollow and has openings at both ends. The openings at both ends of the cross arm 1 are interspersed with an extension arm 3. The extension arm 3 can extend or retract in the opening of the cross arm 1. Both the trailing arm 2 and the two extension arms 3 are provided with mounting pieces 4 for connecting to a rear axle (not shown). The mounting part 4 can be selected according to the model of the rear axle. For example, the mounting part 4 can be a circular fixing part (not shown), and the center of the fixing part is provided with a circular groove (not shown), which is used to connect with the crossbeam Mounting and fixing for the rear axle of the grooved cross member. Another example is that the mounting part 4 is a "concave" shape (not shown in the figure), and the bottom of th...

Embodiment 2

[0052] Please combine Figure 5 and Figure 6 , this embodiment 2 is an improved solution of embodiment 1. Each of the universal wheels 25 is connected to the support base 21 through a shock absorber assembly, the shock absorber assembly includes a chute 33 with the notch facing downward, and the inside of the chute 33 is slidably provided with two sliders. 34, the top of the slider 2 34 is connected to the groove wall of the chute 33 through a spring 2 36, and the bottom of the slider 2 34 is connected to the corresponding universal wheel 25 through a fixed rod 35.

[0053] When the bracket is subjected to vibration from the vertical direction, the slider 2 34 will slide in the chute 33 under the action of the vibration force, and compress the spring 2 36 to make it elastically deform to reduce the vibration, further ensuring the assembly process of the rear axle stability.

Abstract

The invention relates to the technical field of automobile manufacturing, and discloses an automobile rear axle supporting tool that comprises a cross arm and a longitudinal arm perpendicular to the cross arm, wherein the cross arm is hollow, openings are formed in two ends of the cross arm, extension arms are inserted into the openings in the two ends of the cross arm in a penetrating mode, installation pieces used for being connected with a rear axle are arranged on the longitudinal arm and the two extension arms, and an adjusting mechanism for adjusting extension lengths of the extension arms is arranged in the cross arm. The bottom of the cross arm is connected with a supporting base through a buffer mechanism, and a lifting mechanism used for adjusting the height of the cross arm is arranged on the supporting base. According to the automobile rear axle supporting tool, a traditional adjusting mode for the extension lengths of the extension arms in the cross arm is replaced, and through the adjusting mechanism arranged in the cross arm, the extension lengths of the extension arms in the cross arm can be rapidly adjusted, and the batch assembly efficiency of the supporting toolson the automobile rear axles is improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile rear axle bracket. Background technique [0002] The rear axle is the rear drive shaft component of the vehicle's power transmission. For front-drive vehicles, the rear axle mainly plays the role of load-carrying. For rear-drive vehicles, the rear axle also plays the role of driving, deceleration and differential speed in addition to the role of load-bearing. [0003] The general rear axle assembly has a large dead weight and is very inconvenient to assemble, and the rear axle bracket is mostly used for assembly. The existing rear axle support mainly includes a cross arm, a longitudinal arm perpendicular to the cross arm, and two extension arms interspersed at the two ends of the cross arm. The expansion and contraction of the extension arm in the cross arm is mostly regulated by bolts. However, when mass assembly operations are performed, this a...
