Description

Technical Field

[0001] The utility model relates to the technical field of automotive motor shafts, and particularly relates to a new type of automotive motor shaft. Background Art

[0002] A shaft is a cylindrical object that passes through the middle of a bearing, or the middle of a wheel, or the middle of a gear, but a small part of it is square. A shaft is a mechanical part that supports a rotating part and rotates with it to transmit motion, torque, or bending moment. Generally, it is a metal round rod, and each section can have a different diameter. The rotating parts in a machine are installed on the shaft. Among them, a motor shaft is a component that is coaxially arranged inside a motor stator, fixedly installed with the motor stator, and used to output the motor torque. The Chinese patent discloses a motor shaft for a new energy vehicle (authorization publication number CN219139612U), and this patented technology discloses a motor shaft for a new energy vehicle, including a mounting shaft. The inner wall of the mounting shaft is provided with a mounting groove, and the outer wall of the mounting shaft is fixedly installed with a main shaft. An adjusting device for adjusting the position corresponding to an external connecting part is installed on the inner wall of the mounting shaft and the inner wall of the main shaft. The beneficial effect of the utility model is that by installing an organic, bidirectional threaded rod, limiting groove, limiting block, threaded tube, strip-shaped slotted opening, fixed rod, connecting block, and opening, when the motor starts, it drives the annular fixing block connected to the connecting block and the annular mounting block on the annular fixing block to move. By adjusting the change in the positions of the annular fixing block and the annular mounting block, external parts at different positions can be connected, avoiding the problem that the motor shaft cannot be used because the connection position of the external part and the motor shaft does not correspond. This patented technology solves the following deficiencies in the prior art: During the installation process of the existing motor shaft, since the motor shaft is the power source for driving other parts to rotate, due to the different positions of the internal parts in different new energy vehicles, the installation positions on the main shaft of the motor shaft will also be different. Therefore, the different positions of the parts will result in different main shafts of the motor shaft, and the same motor shaft cannot drive the parts at different positions to rotate, making the compatibility of the motor shaft poor.

[0003] However, in the prior art, the length of the motor shaft of an automobile is fixed during production and cannot be assembled and adjusted according to the actual installation environment on the automobile. It is necessary to solve the problem that the length of the motor shaft produced in the prior art can be assembled and adjusted.

[0004] Therefore, those skilled in the art have provided a new type of automotive motor shaft to solve the problems raised in the above background art. Summary of the Utility Model

[0013] The fixed block is fixedly assembled on the docking shaft rod and the ring-shaped mounting part through an external bolt.

[0014] The technical effects and advantages of the present utility model:

[0015] In the present utility model, during the assembly process of the docking shaft structure, by assembling the docking shaft rod onto the transmission shaft rod and using an external screwdriver to rotate the screw rod, the screw rod rotates helically along the docking shaft rod. The rotation of the screw rod pushes the abutting block towards the docking block, driving the inner beveled block to move in the inner beveled groove of the docking block, so that the docking block moves outward to the inside of the first clamping groove. In this way, the docking shaft rod can be stably clamped on the mounting shaft through the docking block. When performing the clamping and assembling between two docking shaft structures, the docking inner rod of one docking shaft rod is clamped inside the second clamping groove of the other docking shaft rod, realizing the extension of the working length of the automotive motor shaft.
