Dual-motor forklift drive axle

Abstract

The invention provides a dual-motor forklift drive axle, and belongs to the technical field of forklift driving. The drive axle comprises two driving mechanisms which are symmetrically arranged left and right, the driving mechanism on the left side comprises a motor assembly and a transmission assembly, the motor assembly comprises a winding drum and a rotating shaft concentric with the winding drum, the left end and the right end of the rotating shaft extend out of the winding drum respectively, and a front end cover and a rear end cover are fixedly connected to the left side and the right side of the winding drum in an attached mode respectively and support the left end and the right end of the rotating shaft through bearings respectively; the transmission assembly comprises a reductiongearbox fixedly connected with the front end cover in an attached mode and a planetary reducer embedded in the reduction gearbox, a gear ring of the planetary reducer which is embedded in the reduction gearbox and fixed, the left end of the rotating shaft penetrates through the front end cover to be in transmission connection with a sun gear of the planetary reducer, and a planetary gear carrier of the planetary reducer is used for outputting torque. The driving mechanism on the right side comprises a motor assembly and a transmission assembly which are the same as the driving mechanism on theleft side, and rear end covers of the two driving mechanisms are fixedly connected in a left-right fit mode.

Description

technical field [0001] The invention belongs to the technical field of forklift driving and relates to a dual-motor forklift driving axle. Background technique [0002] With the continuous development of new energy technology, electric forklifts are also emerging. The driving structure of electric forklifts is quite different from that of ordinary fuel-powered forklifts. For example, a Chinese patent with an application number of 201420552277.0 discloses a drive axle of a motor-driven forklift, which has a hollow shaft motor, and one end of the hollow shaft of the motor is coaxially connected with the support plate of the differential, and the support plate is coaxially fixed On the differential case, the side gear I in the differential and close to the motor is coaxially connected to one end of the long half shaft. The long half shaft is installed in the hollow shaft and arranged coaxially with the hollow shaft. The long half shaft The other end of the shaft and the half ...

AI Technical Summary

Problems solved by technology

[0003] However, this kind of driving axle has a relatively complex structure, is difficult to assemble, and takes up a lot of space, which greatly increases the production cost.
