Embodiment Construction

[0031] A kind of composite wheel structure electric vehicle, see figure 1 , the composite wheel axle structure of the rear wheel is the key connecting part to realize the composite wheel. It is composed of a three-layer structure of the power transmission shaft 5, the fixed bushing 4 and the hub bushing 3, wherein:

[0032] The fixed bushing 4 is used to provide the function of connecting and fixing the composite wheel with the vehicle frame and the drive wheel bracket, and this part is a non-moving part;

[0033] The power transmission shaft 5 is connected to the fixed bushing 4 via a bearing, and is used to provide circumferential torque to the drive wheel (non-load wheel) in the composite wheel, which is a moving part;

[0034] The wheel hub bushing 3 is connected to the outer layer of the fixed bushing 4 via a bearing, and is used for the setting of the load wheel in the composite wheel, and this part is a moving part.

[0035] see figure 2 , the load wheel 1 is fixed i...

Abstract

The invention discloses an electric vehicle with a combined wheel structure and aims to solve the problems of the existing electric vehicle that the power is obviously higher and a driving distance is limited. The electric vehicle with the combined wheel structure comprises a combined wheel formed by a loading wheel arranged at the part of a rear wheel of a frame, a driving wheel, a fixed shaft sleeve, a power transmission shaft and a wheel hub shaft, wherein the loading wheel is sleeved on the wheel hub shaft and the power transmission shaft is provided with a driving wheel bracket; the driving wheel bracket is provided with the driving wheel; the driving wheel is connected with an external power transmission mechanism; and the radius of the driving wheel is less than or equal to one half of the radius of the loading wheel. According to the electric vehicle with the combined wheel structure, the radius size of a driven wheel of the vehicle is increased and the radius size of the driving wheel is reduced, so that the aims of greatly improving the vehicle driving force and greatly saving energy are realized on the premise of not increasing the motive power configuration of the vehicle.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle with a compound wheel structure. Background technique [0002] The currently widely used electric vehicle wheel system is the concept of driven wheel and driving wheel structure. The wheel that is about to rely on the torque transmitted to the circumference of the wheel is called the driving wheel, and the wheel that relies on the thrust of the center of the wheel is called the driven wheel; the driving wheel is also called the driven wheel. bear the vehicle load. The principle of classical wheel kinematics reveals that in this traditional wheel system structure, the larger the radius of the driven wheel, the smaller the required thrust, and the smaller the radius of the driving wheel, the greater the driving force. In practice, people have not respected and made full use of these basic principles. Electric vehicles have always adopted contradictory technica...
