Outer rotor hub motor driven automobile tire online self-inflating and deflating system

Abstract

The invention discloses an outer rotor hub motor driven automobile tire on-line self-inflating and deflating system, belongs to the technical field of automobile driving systems, and aims to realize the on-line self-inflating and deflating function of a tire by utilizing the advantage that a hub motor directly drives a wheel. The online self-inflating and deflating system for the automobile tire driven by the outer rotor hub motor at least comprises a rim with a spoke air passage, a driving motor and an inflating and deflating unit, the driving motor is an outer rotor hub motor, drives the automobile to run and drives the inflation and deflation unit through the action of the electromagnetic clutch; the inflating and deflating unit comprises a rotating air chamber arranged between one end of a stator shaft of the driving motor and a rim, a stator shaft air passage arranged on the stator shaft in a penetrating manner, and an inflating and deflating adjusting mechanism; the stator shaft air passage is respectively connected with the rotary air chamber and the inflation and deflation adjusting mechanism, and the driving motor drives an air pump in the inflation and deflation adjusting mechanism to inflate and deflate tires through compressed air via the stator shaft passage, the rotary air chamber and the spoke air passage.

Description

technical field [0001] The invention relates to the field of driving systems of electric vehicles, in particular to an online self-inflating and deflating system for driving vehicle tires by an outer rotor hub motor. Background technique [0002] With the development of new energy vehicle technology, there are more and more hybrid vehicles and electric vehicles. Compared with traditional cars, the common hybrid vehicles on the market mainly increase the motor, battery and hybrid coupling device. Electric vehicles usually replace the engine with a motor, and are usually equipped with transmission devices such as gearboxes, gearboxes, and drive axles. The electrification of the power system of electric vehicles and the demand for high-efficiency transmission also push the chassis of electric vehicles towards electrification and distribution. drive, as well as changes in characteristic forms such as electromechanical-hydraulic integration and cross-system integration. The dis...

AI Technical Summary

Problems solved by technology

The traditional central inflation and deflation system generally has a central air chamber and an air pump on the chassis of the car, which are connected to the tires through an air circuit. Although there are a small number of patents on the central inflation and deflation system suitable for electric wheels, for example, the Chinese patent publication No. CN210257988 developed a technical solution called an electric wheel assembly with integrated central inflation and deflation functions. However, its overall configuration still follows the design idea of ​​traditional internal combustion engine vehicles, that is, the central air pump is arranged on the body, and is installed separately. Driven by the power source and connected to the tires through the air channel, this structure has not achieved good integration, and the degree of chassis integration is not high
