Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] As shown in the figure, the high-speed electric wheel internal damping device of this embodiment includes a damping damper and a spring damper;

[0026] The damping shock absorber includes a damper housing 1 and a support rod 2 that is worn on the damper housing and is slidably fitted with the damper housing. Both ends of the support rod 2 protrude from the damper housing 1, so The above-mentioned support rod 2 is provided with a damping disc 3 for squeezing the damping liquid;

[0027] The spring damper includes a sleeve seat 4 and a spring 5 located in the sleeve seat, one end of the sleeve seat 4 and the support rod 2 is fixedly connected, the spring 5 is sleeved on the support rod, and the spring 5 One end bears on the damper housing 1 , and the other end of the spring 5 bears on the sleeve seat 4 .

[0028] In this embodiment, the damper h...

Abstract

The invention discloses an inner vibration absorbing device of a high-speed electric wheel. The inner vibration absorbing device of the high-speed electric wheel comprises a damping vibration absorber and a spring vibration absorber. The damping vibration absorber comprises a damper shell body and a supporting rod, wherein a damping disc is arranged on the supporting rod. The invention further discloses the electric wheel. The electric wheel comprises a wheel shaft and a motor stator, wherein the damper shell body is fixed to the wheel shaft, and a sleeve seat and a guide seat are respectively and fixedly connected with the motor stator. According to the inner vibration absorbing device of the high-speed electric wheel and the electric wheel, a wheel hub motor and a brake are connected to the wheel shaft through the inner vibration absorbing device, acting force and counter-acting force between the wheel shaft and the motor are transmitted through the inner vibration absorbing device, the smoothness and comfort in the process when the motor drives an electric car are largely improved, the work environment of the wheel hub motor is improved, the mass of the wheel hub motor and the brake can also play a role of the damping vibration absorber, and the adverse effect caused by increase of the mass under a spring is eliminated. In addition, the damping vibration absorber and the spring vibration absorber are integrated, so that the inner vibration absorbing device of the high-speed electric wheel and the electric wheel are compact in structure, small in size and light in weight.

Description

technical field [0001] The invention relates to a vibration damping device, in particular to a vibration damping device of a high-speed hub motor drive system. Background technique [0002] Due to the aggravation of environmental pollution and energy crisis, electric vehicles have become an important research direction for reducing emissions and saving energy. There are currently two main types of pure electric vehicle drive: centralized motor drive and hub motor drive (including deceleration drive type and direct drive type). The former uses a motor instead of an internal combustion engine to distribute power to each drive wheel through a reducer and a differential. , so as to drive the vehicle; the latter is to arrange the drive motor in the wheel, which can greatly simplify the transmission system, save the space in the compartment, and improve the transmission efficiency. Therefore, electric wheel drive electric vehicles will become an important development direction of...
