Problems solved by technology

But in US6722459, the axle housing is directly fixedly connected with the motor housing, and the motor housing is fixedly connected with the half-shaft casing. Therefore, if the motor is removed, the axle housing will also be removed, and the relevant components in the drive axle It will lose its support, which is not conducive to the installation and maintenance of the motor

Abstract

The invention provides a wheel-side drive axle which comprises an axle housing and a first wheel-side driving system connected with one end of the axle housing; and the first wheel-side driving system comprises an electric machine and a half-axle casing pipe. The wheel-side drive axle is characterized in that the first wheel-side driving system also comprises an installing seat of the electric machine; one end of the installing seat of the electric machine is fixedly connected with the half-axle casing pipe; the other end of the installing seat of the electric machine is fixedly connected with the axle housing; the installing seat of the electric machine is provided with an inner chamber; an output shaft end of the electric machine is arranged in the inner chamber of the installing seat of the electric machine; and the electric machine is fixedly connected with the installing seat of the electric machine. The wheel-side drive axle is added with the installation seat of the electric machine so that the electric machine can be independently dismantled, and the axle housing does not need to be dismantled simultaneously so as to facilitate the assembling of the electric machine and the later-period disassembling and maintenance of the electric machine.

Description

technical field [0001] The invention relates to a wheel side drive axle. Background technique [0002] The power transmission route of a vehicle using an ordinary rear drive axle is the drive motor-(clutch)-transmission-transmission shaft-rear axle main reducer-differential device-half shaft-(wheel-side reducer)-wheels. The power transmission chain is relatively long, and there is a certain amount of energy loss due to gear meshing and shaft transmission. The longer the transmission chain, the greater the energy loss, so the efficiency of the drive system is lower, and the economy of the vehicle is also lower. [0003] In the middle of the ordinary rear drive axle axle housing, the main reducer and differential gear need to be installed, and a raised axle package needs to be added to the axle housing. In addition, for city buses using ordinary rear drive axles, the internal combustion engine (drive motor) and transmission are arranged on the vehicle. The rear end of the fra...
