Technical Field

[0001] The utility model relates to the field of new energy vehicles, in particular to a rear end cover which is convenient for positioning a sealing gasket. Background Art

[0002] After searching Chinese patents, the announcement number is: CN205753745U, a brake motor rear end cover that can not only reduce the volume of the brake motor, but also improve the braking effect of the brake motor, including a motor rear end cover and a yoke body, the outer cover surface of the motor rear end cover is provided with a yoke body, and the motor rear end cover and the yoke body are an integral structure cast in one piece, the axial hole of the motor rear end cover and the axial hole of the yoke body are mutually connected, and the center line of the axial hole of the motor rear end cover coincides with the center line of the axial hole of the yoke body. Advantages: First, the motor rear end cover and the yoke body in the brake motor rear end cover are cast in one piece, thereby reducing the volume of the brake motor; second, the coaxiality between the motor rear end cover axial hole and the yoke body axial hole in the integrally cast motor rear end cover and yoke body is high, thereby not only improving the braking effect of the brake, but also extending the service life of the brake.

[0003] The existing reducer rear end cover is not convenient for positioning the gasket. Generally, when the rear end cover is installed with the reducer housing, a gasket is arranged between the reducer housing and the end cover. When installing the gasket, it is necessary to place the gasket on the surface of the reducer housing and align the holes on the gasket with the fixing holes on the rear end cover to facilitate fastening with bolts. When placing the gasket, due to the narrow connection of the reducer, the gasket is prone to offset when installing the rear end cover. Once the gasket is offset, it needs to be repositioned, which is very troublesome, increases the workload, increases the difficulty of installation, and reduces work efficiency. In order to solve the above problems, we propose a method that is convenient for positioning the gasket on the rear end cover. Utility Model Content

[0006] By adopting the above technical solution, a positioning rod is set on the sealing gasket and a positioning hole is set on the rear end cover body. During installation, the positioning rod is inserted into the positioning hole, and the limit head is engaged with the limit hole under the action of the spring to fix the sealing end, and then it is installed with the reducer. This method can achieve the purpose of easy positioning, avoid the deviation of the sealing gasket, improve the installation efficiency, and facilitate use.

[0007] The utility model is further configured as follows: one end of the limit head is in an arc shape.

[0008] By adopting the above technical solution, one end of the limit head is arranged to be in an arc shape, which facilitates the fixing and removal of the sealing gasket.

[0013] The utility model is further configured as follows: a surface mounting hole of the rear end cover body.

[0014] By adopting the above technical solution and providing the mounting holes, it is easy to install the reducer.

[0015] The utility model is further configured as follows: the material of the sealing gasket is fiber material.

[0016] By adopting the above technical solution and setting the material of the sealing gasket to be fiber material, the sealing performance is good.

[0017] The utility model is further configured as follows: a groove is provided on the surface of the rear end cover body.

[0018] By adopting the above technical solution and providing the groove, it is easy to take out the sealing gasket.

[0019] When the utility model is used and installed, the positioning rod on the sealing gasket is inserted into the positioning hole on the rear end cover body, and the limiting head is engaged with the limiting hole under the action of the spring to fix the sealing gasket, and then the rear end cover body and the reducer housing are installed and fixed, thereby achieving the purpose of facilitating the positioning of the sealing gasket. If the sealing gasket needs to be removed, a tool such as a screwdriver is used to insert it into the groove, pry up the sealing gasket, disengage the limiting head from the limiting hole, remove the sealing gasket, and facilitate the replacement of the sealing gasket.

[0020] The beneficial effect of the utility model is that: the utility model provides a positioning rod on the sealing gasket and a positioning hole on the rear end cover body. During installation, the positioning rod is inserted into the positioning hole, and the limit head is engaged with the limit hole under the action of the spring to fix the sealing end, and then the reducer is installed. This method can achieve the purpose of easy positioning, avoid the deviation of the sealing gasket, improve the installation efficiency, and facilitate use. BRIEF DESCRIPTION OF THE DRAWINGS
