Abstract

The invention discloses a double-tire electric wheel system for an electric coach. The double-tire electric wheel system comprises a hub motor, a motor shell, a planetary mechanism, a wheel rim, a motor shaft and a brake. The wheel rim is connected on a planetary wheel support through bolts, the planetary wheel support is supported on an axle shell through a bearing, the motor shaft is fixed on the axle shell and connected with a rotor, a sun wheel is fixed on the motor shaft, a gear ring is fixed on the motor shell, a planetary wheel is supported on the planetary wheel support, a brake braking caliper is fixed on the axle shell, and a brake braking disc is fixed on the planetary wheel support. By the above structure, power transmission is transmitted onto the motor shaft through the rotor, and power is output onto wheels through a planetary wheel speed reducer taking the sun wheel as an active member and the planetary wheel as a passive member. The electric wheel system can fully utilize space of double tires of the electric coach, the objectives of speed reducing and torque increasing are achieved through the planetary mechanism, and needs on low speed and large torque of the electric coach are met better.

Description

technical field [0001] The invention relates to a wheel hub motor drive system for passenger cars, in particular to a double-tyre electric wheel system for electric passenger cars. Background technique [0002] At present, with environmental pollution and energy depletion, people's sense of crisis is getting heavier. Various new energy vehicles have begun to enter people's field of vision, and various new technologies used in automobiles emerge in endlessly. The emergence of electric wheel technology can make the overall layout of the car have more space utilization. However, due to the installation of motors, brakes, reducers and other components in the wheel hub, the space in the wheel hub needs to be arranged in detail. It is not a simple matter to integrate the above components and meet various conditions such as braking force, driving force and transmission ratio. However, the existing general electric wheel is only aimed at a single wheel hub, and generally there is ...
