Technical Field

[0001] This utility model relates to the field of automotive parts application technology, and in particular to a detachable modular axle protective shell. Background Technology

[0002] The axle is a crucial component of a vehicle, its function being to bear the vehicle's load and maintain normal driving on the road. During vehicle operation, the axle is susceptible to impacts from external objects, wear and tear, and corrosion from dust, mud, and water, thus affecting its service life and safety.

[0003] Currently, protective shells are typically installed on axles to protect them. Most existing axle protective shells are integral structures, which are very inconvenient to install and disassemble. Furthermore, the internal drive unit requires layer-by-layer installation and cannot be assembled separately, reducing installation efficiency. When the protective shell is partially damaged, the entire shell needs to be replaced, increasing the cost of use. Therefore, this utility model proposes a detachable modular axle protective shell.

[0006] The end caps A and B are equipped with drive units, and the two drive units are connected by a drive shaft to drive the wheels on both sides.

[0007] The present invention is further configured such that: a plurality of arc-shaped connecting convex strips are uniformly arranged on the outer wall of the main shell in the circumferential direction, and the two ends of the arc-shaped convex strips are respectively bolted to the end cap A and the connecting part.

[0008] The above technical solution facilitates the reinforcement of the main shell with multiple protrusions, improving stability during use. At the same time, bolt connections are made at the reinforced protrusions to enhance the connection between the main shell and the end cap A and the connecting part.

[0009] The present invention is further configured such that: a bearing seat A is provided at the end face of the end cover A; a limiting protrusion A is provided inside the end cover A and at the position of the bearing seat A; a fixing step A is provided on the inner wall of the end cover A near the limiting protrusion A; an installation cavity is provided in the middle of the end cover A; and multiple sealing grooves are provided inside the end cover A near one end of the main shell.

[0010] Through the above technical solution, the limiting protrusion A is used to position and fix part of the internal drive unit, and the fixing step A is used to fix it with bolts, so that it is firmly installed inside the end cover A, and the output shaft of the drive unit can be stably transmitted through the bearing in the bearing seat A.

[0011] The present invention is further configured such that: a reinforcing ring is fixedly connected to the inner wall of the connecting part, and multiple reinforcing blocks are uniformly fixedly connected to the outer wall of the reinforcing ring at the connection point of the connecting part in the circumferential direction, and the outer wall of the reinforcing ring is embedded in the inner wall of the end cap B.

[0012] The above technical solution facilitates the use of reinforcing rings to stabilize parts of the internal drive unit structure, improving the stability of the drive unit during use, and the use of multiple reinforcing blocks can increase the strength of the reinforcing rings.

[0013] The present invention is further configured such that: the reinforcing ring is arranged in a stepped shape, and multiple reinforcing plates are uniformly fixedly connected to the circumference of the stepped connection; multiple support plates are uniformly fixedly connected to the circumference of the outer wall of the reinforcing ring, and the multiple support plates and multiple reinforcing blocks are located on both sides of the reinforcing ring and are distributed alternately.

[0014] The above technical solution uses multiple reinforcing plates and support plates to improve the strength of the reinforcing ring, thereby providing robust protection for the connected drive unit.

[0015] The present invention is further configured such that: a bearing seat B is provided at the end face of the end cover B, a limiting protrusion B is provided inside the end cover B at the bearing seat B, and a fixing step B is provided inside the end cover B near the middle position.

[0016] The above technical solution facilitates the engagement and installation of the internal drive unit on the limiting protrusion B, and the bolt connection and fixation at the fixed step B, so that the internal output shaft can be stably transmitted through the bearing installed in the bearing seat B.

[0017] The beneficial effects of this utility model are as follows:
