Problems solved by technology

Its disadvantage is that due to the increase of the mass of the drive motor and its transmission components on the wheel shaft of the electric wheel, the total mass of the wheel shaft, that is, the unsprung mass of the suspension, increases, and the dynamic response of the wheel becomes poor, resulting in the so-called vertical suspension. Negative effect, reducing the stability, comfort and safety of the vehicle

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0022] figure 1 It is a schematic diagram of the structure of the electric wheel in the embodiment of the present invention. It can be seen from the figure that the electric wheel consists of a wheel body 1, a built-in suspension 2, a driving motor 3, a flexible coupling 4, a frame suspension beam 5, a bearing 6 and The rotor output shaft 7 is composed. In the electric wheel structure, the fra...

Abstract

The invention provides an electric wheel with a built-in suspension, and relates to the technical field of electric vehicles. A frame overhanging beam which is in rigid connection with a frame is adopted to replace a wheel axle of a traditional wheel, the suspension is internally arranged in the wheel, one end of the suspension is fixed to the frame overhanging beam, and the other end of the suspension is connected with a wheel rim of the wheel through a bearing; and a driving motor is installed on the frame overhanging beam, a rotor of the driving motor is connected with the wheel rim of the wheel through a flexible coupling, and torque transmission and wheel driving are achieved. According to the electric wheel with the built-in suspension, because an in-wheel suspension structure is adopted, the driving motor is installed on the frame overhanging beam, so that the mass of a wheel power device is transformed into the sprung mass portion of the suspension, and the problems that the suspension spring lower mass is increased, and the wheel dynamic response capability is poor due to the fact that a driving motor of an existing electric wheel increases the wheel mass are solved. The electric wheel with the built-in suspension can effectively improve the vehicle running stability and smoothness.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and more specifically relates to an electric wheel with a built-in suspension and a vehicle. Background technique [0002] Electric wheel is a kind of wheel technology driven by motor. It integrates the motor power and its transmission device with the wheel to realize the distributed drive of the vehicle, simplify the vehicle structure and improve the driving performance of the vehicle. Therefore, the electric wheel technology has been widely valued by people. [0003] The overall structure of the existing electric wheel includes a wheel body, a motor and a transmission mechanism thereof, which are all integrated on the wheel shaft, and the wheel shaft is connected to the vehicle frame through a suspension. Its disadvantage is that due to the increase of the mass of the drive motor and its transmission components on the wheel shaft of the electric wheel, the total mass of the wheel shaf...
