Embodiment Construction

[0017] The present invention is described in detail below in conjunction with accompanying drawing:

[0018] refer to figure 1 and figure 2 According to the invention, the wheel motion assembly of the urban electric vehicle includes wheels, ring hub motors, semi-active independent suspensions and actuators of the steering-by-wire system. The technical solution adopted in the present invention is to provide the driving force with the ring-shaped hub motor, and the reverse connection of the ring-shaped hub motor can also provide part or even all of the braking force. The output shaft of the steering gear drives all the components on the steering knuckle 13 to achieve a large angle or even 360° rotation. , the suspension is installed inside the annular hub motor to make the wheel and the annular hub motor jump relative to the steering knuckle 13 along the guide rod sliding bushing 19 .

[0019] The annular hub motor mainly includes the outer rotor 3 of the annular hub motor, t...

Abstract

The invention discloses a wheel motion assembly of a city electric vehicle, comprising wheels, an annular wheel hub motor, a semi-active independent suspension and an actuating mechanism of a steer-by-wire system. The semi-active independent suspension comprises a spring (5), two suspension guide rods (6) which are the same in structure, a magnetorheological vibration absorber (14), two guide rodsliding bushes (19) which are the same in structure and four buffer blocks (20) which are the same in structure. The actuating mechanism of the steer-by-wire system comprises a steering motor and photoelectric encoder combining unit (12), a steering knuckle (13), a torque sensor (15), a master pin bearing (17) and a steering knuckle thrust bearing (18). The rim (2) of the wheel is fixedly connected with an outer rotor (3) of the annular wheel hub motor, and an inner stator (4) of the annular wheel hub motor is connected with the steering knuckle (13) of the actuating mechanism of the steer-by-wire system by virtue of the suspension guide rod (6) in the semi-active independent suspension.

Description

technical field [0001] The invention relates to a wheel assembly applied to an electric wheel vehicle in the city, more specifically, it relates to a wheel motion assembly of an urban electric vehicle. Background technique [0002] Some of the existing pure electric vehicles replace the internal combustion engine of a traditional vehicle with an electric motor, some replace the internal combustion engine and transmission with an electric motor, some use a double motor to drive the wheels at the original drive axle, and some use the motor in the wheel to drive directly wheel. In any case, the suspension and steering of these vehicles are almost the same as those of traditional vehicles: the suspension is connected to the frame in multiple places, and the steering gear, even the actuators of the steer-by-wire system, are mostly arranged in the middle of the frame. This makes the research and development cycle of electric vehicles almost the same as that of traditional vehicle...
