Abstract
The utility model discloses an electromobile rear axle, comprising a half axle, an axle housing, a plate spring support, a hubbed connecting flange, a bearing, an oil seal and a brake device; the axle housing is provided with an oil leakage hole and the plate spring support, wherein one end of the axle housing is welded with the hubbed connecting flange and the other end is fixedly connected with the brake device through a bolt; the half axle is positioned in the axle housing, wherein the oil seal is positioned in the axle housing and adjoined with the hubbed connecting flange, and the bearing is positioned at the neck of the hubbed connecting flange. The electromobile rear axle provided by the utility model is reasonable in design and simple in structure; the bearing is arranged at the end part of the axle housing, so that the friction between the half axle and the axle housing is effectively reduced, and thus the service life of the axle is effectively prolonged.
Description
Technical field
The utility model belongs to a kind of technical field of transportation means, particularly a kind of motor rear axle.
Background technology
At present, the position that the axle shell middle part that battery-driven car uses is connected with motor generally is to only have oil sealing, there is not design bearing can cause the semiaxis right alignment low, cause like this mechanical energy to lose in a large number, thereby the dynamic property that impact is whole, do not consider on the further common axle housing that the malfunctioning gear case leakage of oil of oil sealing meeting enters brake equipment by axle housing and can not discharge, more even can cause brake failure, the potential danger of the traffic accident of causing is arranged.
The utility model content
Technical assignment of the present utility model is to provide a kind of motor rear axle for above prior art deficiency.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of motor rear axle, comprise semiaxis, axle housing, leaf spring holder, band neck butt flange, bearing, oil sealing and brake equipment, wherein said axle housing one end is captiveed joint with brake equipment by bolt, described semiaxis is positioned at axle housing, described axle housing is connected together with band neck butt flange, described axle housing is provided with oil leaking hole and leaf spring holder, wherein said oil sealing is positioned at axle housing and near band neck butt flange, described bearing is positioned at the neck of neck butt flange inboard.
This utility model is reasonable in design, and is simple in structure, and the axle housing end is provided with the friction that the bearing actv. has reduced semiaxis and axle housing tube wall, and then actv. has prolonged the service life of vehicle bridge.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
