Gearbox and pure electric loader power system

Abstract

The invention belongs to a gearbox and a power system. In order to solve the problems that pure electric loaders of 5t and above still use power gear shifting transmissions and corresponding power systems used by transmission fuel loaders, the pure electric loaders are complex in structure, large in size, heavy in weight, many in gears and large in shifting impact, are not suitable for systems with motors as power sources, and power systems suitable for the pure electric loaders are lacked, the invention provides a gearbox and an pure electric loader power system. The gearbox comprises a gear shifting executing mechanism, an input shaft, an intermediate shaft and an output shaft, wherein the input shaft, the intermediate shaft and the output shaft are sequentially arranged in parallel in the longitudinal direction, and the input shaft is connected with an external driving device; a first-gear driving gear, a second-gear driving gear and a sliding sleeve are arranged on the input shaft, and a first-gear driven gear, a second-gear driven gear and an intermediate shaft gear are arranged on the intermediate shaft; an output shaft gear is arranged on the output shaft; and the two ends of the output shaft are connected with a front axle and a rear axle of an external vehicle respectively. The power system comprises a driving motor, a driving motor controller, a gearbox controller, a battery and the gearbox.

Description

technical field [0001] The invention belongs to a gearbox and a power system, in particular to a gearbox and a pure electric loader power system. Background technique [0002] In order to meet the increasingly stringent pollutant emission requirements of non-road mobile machinery, manufacturers have developed pure electric loader powertrains with a working load of 5t and above. Compared with the exhaust emissions of traditional fuel loaders, loaders equipped with pure electric systems Machine, zero exhaust emissions, can comply with the future development trend. [0003] With the development of pure electrification of 5t and above loaders, the power system of the loader still mainly uses the power shift transmission and the corresponding power system used by the traditional fuel loader. However, the traditional power shift transmission is complex in structure, large in size, and heavy in weight, which restricts the development of pure electric loaders; in addition, its char...
