Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] As shown in Figures 1-2, the in-wheel motor has a shell composed of a motor main shell 5 and a motor cover 18 that are mutually fixed by screws. The bearing 4 and the bushing 3 in the hole are used as supports, and the stator left end cover 6 and the stator right end cover 12 fixedly connected with it are set on the main shaft, that is, the stator right end cover is connected with the main shaft by a flat key 21, and the stator left end cover is connected to the right end of the stator through screws. The cover is connected so that the left and right end covers of the stator and the main shaft form a static connecting body. In the left and right end covers of the stator, there are motors buckled by the inner shoulder blades, and the cables connected to the motors are drawn out from the main shaft cable hole 2.

[0014] The motor is composed of...

Abstract

The present invention discloses a hub motor. It includes motor main case and motor cover which are mutually fixedly connected, on the main shaft of its shaft centre the stator left and right end covers fixedly connected with said motor are cover-mounted, said motor can be covered by the left and right end covers of stator and mounted in the interior of motor main case, in the interior of rotor iron core of motor a rotor liner is mounted, and between said motor and planetary reducing mechanism a roller clutch formed from clutch outer ring, roller retaining frame, roller and lefa spring is set, and said planetary reducing mechanism is a double-geared speed reducing one formed from driving gear, planetary gear on planetary spindle, gear III, bearing gear and internal gear, the internal gear is fixedly connected with motor cover so as to implement power transmission.

Description

technical field [0001] The invention relates to a motor, especially a hub motor capable of driving a hub to rotate. Background technique [0002] Electric vehicles and electric bicycles have been widely used and developed due to their advantages of no pollution, no noise, lightness, convenience, safety, reliability, and low cost. The heart of electric vehicles and electric bicycles is the hub motor, and the performance of the motor will depend on the Directly affect the performance of electric vehicles and electric bicycles, such as power, speed, climbing ability, etc., all await further development and research. The technical solution disclosed in Chinese patent 00253865.2 "Electric Bicycle with Planetary Gear Differential Mechanism" is to use a planetary gear mechanism to drive the hub to rotate, so that it can be driven by manpower and motor to increase the vehicle speed and increase the climbing ability , and no matter how fast or slow the motor speed is, you can freely...
