Problems solved by technology

However, when the motor is adjusted to run at a low speed, its output power and torque will decrease correspondingly, making the electric vehicle powerless during the uphill process, and the current amplifies the motor to heat up when going uphill, making the motor and the control system easy to burn out

Embodiment 1

[0031] Such as Figure 1 to Figure 6 Shown is the first embodiment of the electric vehicle motor transmission of the present invention. The electric vehicle transmission includes a box body 1 and related transmission mechanisms. The box body 1 is connected with a flat fork 1A, and the flat fork 1A is used to connect the entire machine on the frame.

[0032] After the motor 2 is energized and rotated, the motor shaft gear 4 at the end of the motor shaft 3 drives the bridge gear 5 to rotate, and the bridge gear 5 meshes with the main shaft input gear 7 to rotate so as to drive the main shaft 8 to rotate.

[0033] Such as figure 1 As shown in , the first gear output gear 10A and the second gear output gear 10 are fixed on the output shaft 25, and the diameters and the number of teeth of the two output gears are different. The corresponding idle sleeve on the main shaft 8 has a second gear driving gear 9 meshing with the second gear output gear 10, and the transmission speed rat...

Embodiment 2

[0038] Such as Figure 7 to Figure 11 Shown is the second embodiment of the electric vehicle motor transmission of the present invention. The electric vehicle transmission includes a box body 1 and related transmission mechanisms. The box body 1 is connected with a flat fork 1A, and the flat fork 1A is used to connect the entire machine. on the frame.

[0039] After the motor 2 is energized and rotated, the motor shaft gear 4 at the end of the motor shaft 3 drives the bridge gear 5 to rotate, and the bridge gear 5 meshes with the main shaft input gear 7 to rotate so as to drive the main shaft 8 and the active block 16 to rotate.

[0040] When the motor 2 drives the main shaft 8 and the active block 16 to rotate counterclockwise, the moving part 15 is separated from the second gear driving gear 9 under the action of the separation spring 17, and the power of the main shaft 8 cannot be transmitted to the second gear driving gear 9. The driving gear 9 only idles in reverse aroun...

Embodiment 3

[0044] Such as Figure 12 to Figure 17 Shown is the third embodiment of the electric vehicle motor transmission of the present invention. The electric vehicle transmission includes a box body 1 and related transmission mechanisms. The box body 1 is connected with a flat fork 1A, and the flat fork 1A is used to connect the entire machine. on the frame.

[0045] After the motor 2 is energized and rotated, the motor shaft gear 4 at the end of the motor shaft 3 drives the bridge gear 5 to rotate, and the bridge gear 5 meshes with the main shaft input gear 7 to rotate so as to drive the main shaft 8 and the two driving gears to rotate.

[0046] When the motor drives the main shaft 8 and the first gear driving gear 9A and the second gear driving gear 9 to rotate clockwise, the two driving gears drive the output gear to rotate. The first gear driving gear 9A meshes with the reversing gear 14 to rotate, and the power passes through the reversing gear 14 and then meshes with the first...

Abstract

The invention discloses the technical field of power transmission of electromobile motors and solves the problem that a motor can not output different speeds and different torques under same rotating speed. A transmission of an electromobile motor comprises a box body, wherein the box body is provided with a motor, the motor is provided with a motor shaft, the motor shaft is in transmission connection with a main shaft, a drive gear is sleeved on the main shaft, a two-gear drive gear is in meshing transmission with an output gear fixed on an output shaft, a chute is processed on the main shaft, a sliding member is connected with a one-gear drive gear or two-gear drive gear under the action of the chute when the shaft rotates, the one-gear drive gear drives a one-gear output gear through a reversing gear so as to drive an output shaft to rotate; and the sliding member is combined or separated from the two-gear drive gear or one-gear drive gear through positive or negative rotation of the main shaft, therefore, one-gear or two-gear power output is switched.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle power transmission, in particular to the technical field of positive and negative variable speed motor transmission. Background technique [0002] The driving power of a common electric vehicle is mainly changed by adjusting the voltage and current input to the motor and changing the speed of the motor. However, when the motor is adjusted to run at a low speed, its output power and torque are correspondingly reduced, making the electric vehicle weak during the uphill process, and the current amplifies the motor to generate heat during uphill, which makes the motor and the control system easy to burn out. Contents of the invention [0003] In order to solve the above shortcomings, the purpose of the present invention is to provide a simple structure, convenient shifting operation, small size, and can obtain different vehicle speeds and different torques at the same speed at the same time...
