Problems solved by technology

[0005] The geared motor power unit consisting of DC motor + reducer + braking device + unpowered wheels is high in cost and large in size. Compared with the chassis of electric unmanned vehicles with a smaller size, it is more difficult to arrange; most of the chassis The turning radius is large, it is impossible to achieve in-situ rotation, and the steering flexibility is poor; the solution that can achieve rotation is expensive or has a cumbersome structure and low efficiency

Abstract

The invention discloses a hub motor based wheel mechanism, a chassis of an electric unmanned vehicle and the electric unmanned vehicle, and relates to the technical field of electric unmanned vehicles. The hub motor based wheel mechanism specifically comprises a supporting part, a turning part and a hub motor, wherein the supporting part is connected to a vehicle body; the turning part is connected to the supporting part and can be rotated relative to the supporting part; a hub motor is arranged on the turning part. According to the mechanism adopting the abovementioned implementing mode, themechanical structure is extremely simplified; the structure size is reduced; the turning is flexible; the ground adaptability is high; the efficiency and the reliability are high; and the cost is low.

Description

technical field [0001] The invention relates to the technical field of electric unmanned vehicles, in particular to a wheel mechanism based on in-wheel motors, an electric unmanned vehicle chassis and an electric unmanned vehicle. Background technique [0002] Electric unmanned vehicles are different from unmanned vehicles in that they are small in size, light in weight, and low in speed. The requirements for the chassis mainly focus on simple structure, small weight, low cost, and flexibility. However, since there is no uniform standard for electric unmanned vehicles, and the requirements for size and load capacity vary, various chassis solutions have emerged to meet various actual needs. [0003] There are a variety of driving and steering schemes for electric unmanned vehicles. Among them, the geared motor power unit composed of DC motor + reducer + brake device + unpowered wheels is more common. Combined with various mechanical steering structures, steering or in-situ s...
