Problems solved by technology

However, when the speed decreases, the power of the electric vehicle will also decrease when the speed is reduced. This will cause inability to climb the slope when the road is muddy, heavy-loaded or climbing. If the current to the DC motor is increased at this time ( Voltage) supply, it will increase the load of the DC motor, which will easily cause damage to the DC motor and shorten the service life of the battery

Embodiment

[0025] Example: see Figure 1 to Figure 5 , a multi-gear gearbox for an electric vehicle, comprising a box body, a power input shaft 1 and a power output shaft 2 . A power input gear I3 and a power input gear II4 are arranged on the power input shaft 1, and both the power input gear I3 and the power input gear II4 can be rotatably set on the power input shaft 1; during processing, the power input gear Ⅰ3 and power input gear Ⅱ4 are connected with the power input shaft 1 through ball bearings; thus, free forward and reverse rotation can be performed. A sliding member 5 is arranged between the power input gear I3 and the power input gear II4. In practice, a feather key is arranged on the power input shaft 1 between the power input gear I3 and the power input gear II4 along its axial direction. The inner side of the sliding part 5 is provided with a keyway, and the sliding part 5 is slidably connected with the power input shaft 1 through the cooperation of the keyway and the fea...

Abstract

The invention discloses a multi-gear gearbox for a motor vehicle. The multi-gear gearbox for the motor vehicle comprises a box, a power input shaft and a power output shaft; the power input shaft is provided with a power input gear I and a power input gear II; a high-speed gear transmission shaft, a low-speed gear transmission shaft and a reverse gear shaft are arranged in the box; the high-speedgear transmission shaft is provided with a high-speed gear driving gear, a low-gear speed reducing gear and a high-speed gear driven gear; the low-speed gear transmission shaft is provided with a low-speed gear driving gear and a low-speed gear driven gear; the reverse gear shaft is provided with a reverse gear driving gear and a reverse gear driven gear; the power output shaft is provided with apower output gear; and the power output gear is engaged with the high-speed gear driven gear, the low-speed gear driven gear and the reverse gear driven gear at the same time. The multi-gear gearbox for the motor vehicle is simple in structure, can perform multi-gear power output, and enables the motor vehicle to obtain higher power output at high speed or low speed.

Description

technical field [0001] The invention relates to the field of electric vehicle gearboxes, in particular to a multi-gear gearbox for three-wheel or four-wheel electric vehicles. Background technique [0002] The current three-wheel or four-wheel electric vehicles are mainly driven by the DC motor through the transmission chain to drive the drive shaft or through the drive shaft through the differential to drive the drive shaft; The current (voltage) of the DC motor realizes infinitely variable speed. However, when the speed decreases, the power of the electric vehicle will also decrease when the speed is reduced. This will cause inability to climb the slope when the road is muddy, heavy-loaded or climbing. If the current to the DC motor is increased at this time ( voltage) supply, it will increase the load of the DC motor, which will easily cause damage to the DC motor and shorten the service life of the battery. Contents of the invention [0003] In view of the above-ment...
