Side-hung driving motor assembly of electric vehicle

Abstract

The invention provides a side-hung driving motor assembly of an electric vehicle, and belongs to the technical field of electric vehicles. The problem that an existing electric vehicle with a side-hung driving motor is poor in balance is solved. The electric vehicle comprises wheels, the side-hung driving motor assembly comprises a bottom fork and a motor, the bottom fork comprises a left fork armand a right fork arm, the wheels are arranged between the left fork arm and the right fork arm, the side-hung driving motor assembly further comprises a speed reducing and changing mechanism, the left fork arm is bent towards the wheels, and a concave installation space is formed in the outer side of the left fork arm. The motor is located in the installation space and fixedly connected with theleft fork arm, an installation cavity is formed in the inner side of the rear end of the left fork arm, the speed reducing and changing mechanism is arranged in the installation cavity, the inner sidewall of the right fork arm is concavely arranged in the direction away from the wheel to form a receding space, and the motor is connected with the wheel through the speed reducing and changing mechanism. The electric vehicle with the side-hung driving motor has the advantage of being good in balance.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and relates to a side-mounted driving motor assembly of an electric vehicle. Background technique [0002] Electric vehicles are favored by consumers because of their advantages such as convenient driving, easy parking, and environmental protection. As the core component of an electric vehicle, the drive motor has a great impact on its performance, efficiency, and reliability. In order to improve the heat dissipation performance of the drive motor, some existing electric vehicles use side-mounted installations to install the motor and the deceleration device. . [0003] Existing side-mounted drive motors for electric vehicles, for example, Chinese patent literature discloses a side-mounted motor drive mechanism and an electric vehicle [application number: 201921815154.0; authorized announcement number: CN210707794U], wherein the side-mounted motor drive mechanism includes a motor, a de...

AI Technical Summary

Problems solved by technology

[0004] For electric vehicles with this structure, the motor drive mechanism is mounted on the side, the front end of the motor is fixedly connected to the rear cradle through fasteners, the outer end of the motor is protruding, and the protruding part of the motor is larger in size. The center of gravity of the motor is far away from the central axis of the electric vehicle, which affects the riding balance of the electric vehicle to a certain extent. At the same time, when the electric vehicle is tilted and parked, the distance between the motor and the ground is too close, which also affects the balance of the electric vehicle when parked. sex

At the same time, the electric vehicle with this structure, the motor and the deceleration device are an integrated structure, which is troublesome to disassemble and maintain
