Abstract

The invention discloses an electric forklift driving system which comprises a wet-type mechanical brake driving system and an electromagnetic brake driving system, the wet-type mechanical brake driving system comprises a reduction gearbox and a motor, and the reduction gearbox comprises a wet-type mechanical brake system, a first-stage speed reducer, a second-stage speed reducer and an axle. Through meshing transmission of a helical gear of primary speed reduction and meshing transmission of a planetary gear train of secondary speed reduction of the reduction gearbox, high efficiency and low noise are achieved, meanwhile, integrated design of wet mechanical braking is achieved, and through the design of increasing or reducing friction plates, the braking requirements of electric forklifts of different tonnages are met, the universal design of wet-type mechanical brake components such as a brake rod and a pressing plate is achieved, the purpose of saving cost is achieved, the design of different versions of wet-type mechanical brake and electromagnetic brake of a driving system is achieved by changing the output shaft of the motor, and the requirements of different clients are met.

Description

technical field [0001] The invention belongs to the technical field of drive systems, in particular to an electric forklift drive system. Background technique [0002] The existing electric forklift driving system generally adopts a single-motor acceleration and deceleration drive axle device (hereinafter referred to as a single-drive bridge). A general single-drive bridge mainly includes a drive motor, a gear reducer, a differential, a half shaft, a bridge, and a braking system. The power is transmitted through the electric motor to the gear reduction box, and then to the axle shaft through the differential, and finally drives the wheels. For larger-tonnage forklifts, the required motor volume is larger, and the required deceleration is relatively large. The entire drive system is bulky, which is not conducive to the overall layout of the forklift, and the forklift has no advantages in vehicle parameters. [0003] Therefore, it is necessary to invent a driving system of a...
