Embodiment Construction

[0026] see figure 1 and figure 2 , is a specific embodiment of a pure electric wheel-side reducer housing. The pure electric wheel side reducer housing includes a reducer front case 1, a reducer rear case 2 and a gasket 3. The input end cavity wall of the front casing 1 of the reducer is provided with a through input shaft hole 4, and the output end cavity wall of the front casing 1 of the reducer is provided with a through output shaft hole 5, in order to facilitate the connection between the reducer and the power source. If the drive motor is fixedly connected, the outer wall of the input end of the reducer front housing 1 is provided with a connecting flange 17, which can be reliably installed and fixed through the flange connection. The cavity walls of the front housing 1 of the reducer and the rear housing 2 of the reducer are respectively provided with corresponding bearing mounting seats 6, and a group of bearing mounting seats corresponding to the cavity walls of th...

Abstract

The invention discloses a rim speed reducer shell of a pure electric vehicle. The rim speed reducer shell of the pure electric vehicle comprises a transmission front shell, a transmission back shell and a sealing pad; the transmission front shell is provided with an input shaft hole and an output shaft hole; corresponding bearing mounting bases are respectively arranged on cavity walls of the transmission front shell and the transmission back shell; a first acoustic insulation layer is arranged on the cavity wall of the transmission front shell, and is positioned between the input shaft hole and the side wall of an input end of the transmission front shell; a second acoustic insulation layer is arranged on the cavity wall of the transmission back shell, and is adapted to the first acousticinsulation layer on the cavity wall of the transmission front shell; the transmission front shell and the transmission back shell are closed to form a shell body with a silencing cavity and a speed reducing cavity; the shell body is provided with an oil overflow pipe, an oiling pipe and a ventilation pipe; inner ends of the oil overflow pipe, the oiling pipe and the ventilation pipe respectivelypenetrate through the silencing cavity, and communicate with the speed reducing cavity; and the sealing pads are positioned between the transmission front shell and the transmission back shell, seal agap between the side walls of the transmission front shell and the transmission back shell, and respectively seal a first silencing cavity and a second silencing cavity.

Description

technical field [0001] The invention relates to the field of reducers, in particular to a pure electric wheel-side reducer housing. Background technique [0002] Under the requirements of the country to vigorously promote new energy buses, domestic hybrid buses, pure electric buses, logistics vehicles, etc. are developing rapidly, and the proportion of new energy vehicles is getting higher and higher. In some cities, the proportion of new energy buses has exceeded that of traditional power buses. [0003] Most of the power systems of the first generation of new energy buses do not use transmission mechanisms, but use engine + motor or pure motor as the power system. With the improvement of the country's requirements for new energy vehicles and the feedback from the use of the first generation of new energy buses in the market, it is urgent to add a transmission mechanism to its power system to optimize and improve system performance. [0004] Pure electric wheel drive is t...
