Abstract

The invention provides a steering device for a hub motor, an angle unit, a walking device and an electric vehicle, and belongs to the field of power and auxiliary driving of vehicles. The steering mechanism comprises a steering arm assembly and a steering driving assembly, the steering arm assembly comprises a frame connecting part located at the upper end and a lower swing arm connecting part located at the lower end, the frame connecting part is used for being connected with a frame corresponding to a hub motor, and the lower swing arm connecting part is used for being connected with a lower swing arm of a suspension corresponding to the hub motor; the steering driving assembly drives the steering arm assembly to enable the hub motor to rotate around the vertical rotation line, the steering driving assembly is located on the side, away from the hub, of the hub motor, and the lower end of the steering driving assembly is arranged to be lower than the highest position of the wheel where the hub motor is located. A transmission steering structure between the steering device and the lower swing arm of the suspension is omitted, the chassis can be flat, the loading height and mass center of the chassis are reduced, and the utilization rate of the space above the chassis is increased.

Description

technical field [0001] The invention relates to the power and auxiliary drive application fields of vehicles, in particular to a steering device, an angle unit, a running device and an electric vehicle for in-wheel motors. Background technique [0002] The in-wheel motor is installed on the wheel, and the use of the in-wheel motor can integrate the power system, transmission system and braking system of the car together to improve space utilization. The combination of wheel and in-wheel motor can be applied to equipment with walking requirements, such as electric vehicles. [0003] In the existing in-wheel motor-based electric vehicle, the steering system includes a steering drive assembly for providing steering driving force to the wheels, the steering drive assembly includes a steering motor arrangement and a reducer, and the steering drive assembly is arranged on the positive side of the wheel. Above, the chassis is provided with an upwardly protruding structure for the ...
