Embodiment 1

[0014] Such as figure 1 As shown: the motor is composed of a stator part 1 fixed in the casing 3 and a rotor part 2 located in the stator part; the differential is embedded in the rotor part 2 and supported by a bearing (not shown in the figure). The gear carrier 7 in the casing 3, the two planetary bevel gears 4 installed in the gear carrier through the gear shaft 8, are installed in the gear carrier 7 through the bearing (not shown in the figure) and are connected with the two planetary bevel gears 4 at the same time. The meshing right sun bevel gear 5 is composed of the left sun bevel gear 10 installed in the gear frame 7 through bearings (not shown in the figure) and meshing with the two planetary bevel gears 4 at the same time; the right sun bevel gear 5 and the right half shaft 6 Fixedly connected, the left sun bevel gear 10 is fixedly connected with the left half shaft 9.

Embodiment 2

[0016] In order to facilitate the adjustment of the rotating speed of the electric vehicle, on the basis that the basic structure is the same as that of Embodiment 1, the present invention can also adopt such figure 2 The structure shown: the left end of the differential is connected to the left speed reducer, and the right end of the differential is connected to the right speed reducer. The left speed reducer consists of a left speed reduction case 11 fixed on the left side surface of the casing 3, a left driving gear 12 which is located in the left speed reduction case and connected with the left sun bevel gear 10, and passes through a bearing (not shown in the figure). ) is supported in the left reduction box 11 and is composed of the left output gear 16 meshed with the left driving gear, and the left half shaft 9 integrated with the left output gear. The right reducer is fixed on the right side surface of the casing 3 The right reduction box 14, the right driving gear 13 ...

Abstract

The invention discloses an electric vehicle differential driving mechanism improved structure, belongs to an electric vehicle driving mechanism, and aims to provide an electric vehicle driving mechanism which has the advantages of small size, light weight and high transmission efficiency. The electric vehicle differential driving mechanism improved structure comprises a motor and a differential mechanism, and is characterized in that the motor consists of a stator component (1) which is fixed in a shell (3) and a rotor component (2) which is positioned in the stator component; the differentialmechanism consists of a gear carrier (7) which is embedded in the rotor component (2) and is supported in the shell (3), two planet bevel gears (4) which are arranged in the gear carrier (7) througha gear shaft (8), a right sun bevel gear (5) which is arranged in the gear carrier (7) and is meshed with the two planet bevel gears (4) simultaneously, and a left sun bevel gear (10) which is arranged in the gear carrier (7) and is meshed with the two planet bevel gears (4) simultaneously. The electric vehicle differential driving mechanism improved structure has the advantages of simple structure, reliable performance.

Description

technical field [0001] The invention relates to a differential drive mechanism of an electric vehicle, in particular to an improved structure of the differential drive mechanism of an electric vehicle; it belongs to the drive mechanism of an electric vehicle. Background technique [0002] The electric vehicle differential drive mechanism is the drive assembly of the electric vehicle, usually consisting of a motor, a reducer connected to the motor, and a differential connected to the reducer. Since the three major components of the motor, reducer, and differential are independent, there are defects such as complex structure, large volume, heavy weight, low transmission efficiency, and high noise, which need to be improved urgently. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the present invention aims to provide an improved structure of the electric vehicle differential drive mechanism with small volume, light weight and high ...
