Abstract

The invention discloses a wheel-side motor driving device, and belongs to the technical field of electric driven vehicles. The wheel-side motor driving device comprises a supporting mechanism, wherein a tyre mechanism is connected with the supporting mechanism; a stator mechanism is arranged at the edge of the tyre mechanism, and is connected with the supporting mechanism; a rotor mechanism is arranged in the stator mechanism, and is connected with the supporting mechanism; the rotor mechanism adopts a hollow structure; a brake is arranged in the hollow structure of the rotor mechanism; a transmission mechanism is connected with the rotor mechanism, and is connected with the tyre mechanism; a suspension mechanism is connected with the supporting mechanism. According to the wheel-side motor driving device disclosed by the invention, the size of axial space is compressed, so that requirements for the limitation to space, the weight and the torque of a vehicle with an independent suspension are met.

Description

technical field [0001] The invention relates to the technical field of electric drive vehicles, in particular to a wheel-side motor drive device Background technique [0002] In recent years, in the technical field of electrically driven vehicles, in-wheel motor drive devices integrated in wheels have received widespread attention. In a traditional mechanical transmission vehicle, a single engine generates power, which is transmitted to the axle after being shifted by the gearbox, and then transmitted to the driving wheels on both sides to drive the vehicle after being split by the axle. Different from the driving mode of traditional vehicles, vehicles driven by wheel motors generate electricity from batteries or generator sets, and transmit the power to the wheel motor devices located in the wheels for direct drive. The number of wheel motors is generally an even number (two above). When braking, the braking effect of the wheel motor during power generation bears or parti...
