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

[0036] Such as Figure 1 to Figure 5 Shown is the first embodiment of the electric vehicle 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 on the frame.

[0037] 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.

[0038] Such as figure 1As shown in , the output shaft 25 is provided with a first-gear output gear 10A and a second-gear output gear 10, the second-gear output gear 10 is fixed on the output shaft 25, and the first-gear output gear 10A is sleeved on the output shaft 25. A one-way clutch 22 is arranged between the gear output gear 10A and the output shaft 25, and the diamete...

Embodiment 2

[0043] Such as Figure 6 to Figure 10 Shown is the second embodiment of the electric vehicle 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 on the frame.

[0044] 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.

[0045] When the motor drives the main shaft 8 and the first gear driving gear 9A to rotate clockwise, 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 spindle is idling. Such as Figure 4 As shown, the first gear ...

Embodiment 3

[0049] Such as Figure 11 to Figure 15 Shown is the third embodiment of the electric vehicle 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 on the frame.

[0050] 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.

[0051] When the motor drives the main shaft 8, 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, and the moving part 15 is separated from the driven part 21 under the action of the separation spring 17 At this time, the power of the first gear output gear 1...

Abstract

The invention relates to a transmission for electric vehicles, belongs to the technical field of power transmission for electric vehicles and realizes that different speed and torque can be output on the condition of the same revolution speed of a motor. The transmission for electric vehicles comprises a case, a motor is arranged in the case and provided with a motor shaft, the motor shaft is in transmission coupling with a spindle, a drive gear is fixed on the spindle, a second-gear drive gear is in meshing transmission with an output gear sleeved on an output shaft, flutes are machined on the spindle, a slider is connected with the second-gear drive gear under action of the flutes when in rotation of the spindle, the second-gear drive gear meshes with the output gear to drive the output shaft to rotate, and a first-gear drive gear drives a first-gear output gear through a reversing gear so as to drive the output shaft to rotate.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle power transmission, in particular to the technical field of forward and reverse speed change motor transmission. Background technique [0002] The driving power of the existing 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...
