Abstract

The invention discloses a gearbox for an electric vehicle. The gearbox is composed a box body, an input shaft, an input shaft gear, a variable shaft gear, a variable shaft, a helical gear, a sliding claw, a high-speed gear, a duplex gear, a clutch, an output shaft, a low-speed gear, a carrier gear and a supporting shaft, wherein the box body fixes the position of the input shaft; when the input shaft is rotated, torque can be transmitted to the variable shaft by the variable shaft gear; the variable shaft is fixedly connected with the helical gear; the forward and backward relative movement between the helical gear and the sliding claw is determined by the rotation direction of the helical gear, if the sliding claw is clamped to the high-speed gear, torque can be transmitted to the outputshaft through the duplex gear and the clutch; and if the sliding claw is clamped to the low-speed gear, torque can be transmitted to the output shaft through the duplex gear and the clutch after beingsubjected to variable speed by the carrier gear, and thus the effect of changing the rotation direction of the input shaft to change the rotation speed of the output shaft is obtained.

Description

technical field [0001] The present invention relates to the technical field of variable conversion devices, in particular to a gearbox for electric vehicles. Background technique [0002] With the development of society and the demand for environmentally friendly travel, electric car seats, a very environmentally friendly means of transportation, have increasingly entered people's lives. Electric cars need to adjust their speed during use. The current gearbox input The gear meshes with the transmission gear, and through the transmission of the first-speed driving gear and the second-speed driving gear connected to the transmission gear, the first-speed driven gear and the second-speed driven gear are driven to rotate, so that the speed of the motor can be changed and transmitted. The mechanical transmission is complicated when shifting gears, which is not conducive to the problem of fast shifting of electric vehicles. Contents of the invention [0003] The purpose of the ...
