Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings. The following description is merely exemplary in nature and does not limit the scope of use of the invention.

[0031] Such as figure 1 As shown, the second-speed transaxle of a pure electric commercial vehicle is mainly composed of a drive motor 202, a two-speed transmission 14, a final reducer 60, a differential 220, an integral axle housing 230, and a left / right wheel-side planetary reducer 310 / 320 And left / right drive wheel 252 / 254 forms.

[0032] The transmission 10 is a transverse transmission, and the transmission includes a transmission case 14 , an input shaft 12 , an output gear 60A, a gear system 18 and the like. The input shaft 12 is connected to a rotor shaft 204 of a drive motor 202 . The output gear 60A meshes with the final drive driven gear 60B.

[0033] The transmission housing 14 includes a first wall 102 , a second wall 104 , a third wall 106 , a ...

Abstract

The invention discloses a second-speed change drive axle of a pure electric commercial vehicle and the pure electric commercial vehicle. The second-speed change drive axle comprises a drive motor, a second-speed transmission, a main transmission, a differential mechanism, an integrated axle shell, a wheel-side planetary reducer and drive wheels, wherein the drive motor is fixedly connected to a second-speed transmission shell; the second-speed transmission is fixedly connected to the axle shell, and is provided with an input shaft, an output gear, two gear groups and one sliding meshing sleeve; each gear group comprises an active cylindrical gear and a passive cylindrical gear; the sliding meshing sleeve is arranged between the passive cylindrical gear of the first gear group and the passive cylindrical gear of the second gear group; the sliding meshing sleeve slides on a splined hub; the splined hub is fixedly connected with an output shaft; when the sliding meshing sleeve slides to one side, the output shaft is connected with the first gear group; and when the sliding meshing sleeve slides to the other side, the output shaft is connected with the second gear group. The second-speed change drive axle has the advantages of compact structure, light weight, high system efficiency, saving of electric energy and capability of realizing a high speed ratio.

Description

technical field [0001] The invention belongs to the field of pure electric commercial vehicle drive train products. More specifically, the present invention is a second-speed transaxle for a pure electric commercial vehicle. The transaxle integrates a transverse drive motor and a cylindrical gear transmission, and is a rear-wheel drive axle capable of realizing a two-speed transmission function. Background technique [0002] The existing pure electric commercial vehicle power system mainly has the following two forms: one is that the drive motor directly transmits power to the drive axle through the drive shaft, and the other is that the drive motor is connected to the gearbox and then transmits power to the drive axle through the drive shaft. bridge. The disadvantages of the first form include: the weight of the motor is large; the range of torque and speed is relatively narrow; the high efficiency area of ​​the system is small; and the structure is not compact enough. Th...
