Problems solved by technology

The motor that drives the hub is located in the hub body, so there is a problem of poor heat dissipation, which will lead to a series of problems such as an increase in the temperature of the gearbox and a reduction in the service life of the components.
The motor is a high-speed motor, and the driving hub adopts two-stage speed reduction, which leads to the problem of low output efficiency

Abstract

The invention provides an electric vehicle variable speed drive hub, and belongs to the technical field of machine engineering. The electric vehicle variable speed drive hub solves the problem that an existing electric vehicle variable speed drive hub is poor in heat dissipation performance, loud in noise and low in output efficiency. The electric vehicle variable speed drive hub comprises a fixing shaft, a hub steel ring, a motor and a speed reducer, wherein the hub steel ring is positioned on the fixing shaft; the speed reducer is located in the hub steel ring, and the motor is located on one side of the speed reducer and located outside the hub steel ring; the motor is composed of a stator and a rotor, the stator is fixedly connected with the fixing shaft, and the rotor is positioned on the fixing shaft; the speed reducer comprises a box body, an input gear shaft, an output gear shaft and an overrun clutch, the box is fixedly connected with the fixing shaft, the input gear shaft is connected with the rotor, and the output gear shaft is fixedly connected with the hub steel ring; the rotor and the hub steel ring are connected through the overrun clutch. The electric vehicle variable speed drive hub has the advantages of being good in heat dissipation effect, high in universality and low in noise.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and relates to a driving wheel hub of an electric vehicle, in particular to a variable speed driving wheel hub of an electric vehicle. Background technique [0002] In short, an electric vehicle is a locomotive driven by electricity. Such as electric bicycles and electric motorcycles. [0003] An electric motorcycle includes a body, a driving hub, and a power supply, among which the driving hub is a driving element. [0004] At present, there are mainly two kinds of speed change devices used for driving the hub, one is electronic stepless controller speed change, and the other is mechanical speed change. Electronic stepless controller variable speed can obtain from 0 to the highest speed of the motor, and has a good speed change curve, but its output torque is directly consistent with the change of the input current of the motor; when the voltage is constant, the motor The great...
