Abstract

The invention relates to a transmission device for an oil-electricity hybrid power loader. The transmission device comprises an engine (1), a clutch (2), a clutch output driven gear (3), a clutch output driving gear (4), a power output driving gear (5), a steering pump driving gear (6), a working pump driving gear (7), a steering pump (8), a working pump (9), a reverse gear brake (10), a reverse gear planetary row (11), a forward gear brake (12), a forward gear planetary row (13), a second gear clutch (14), a motor output reduction planetary row (15), a motor (16), an output driving gear (17)and an output driven gear (18). According to the working condition of the loader, a plurality of transmission modes are provided, and the transmission device can realize all loader working condition functions such as high-speed driving charging, engine idling parking charging, braking energy recovery, pure electric starting and driving and hybrid power mode running.

Description

technical field [0001] The invention belongs to the technical field of a parallel hybrid power loader transmission device, in particular to a transmission device for an oil-electric hybrid power loader. Background technique [0002] Energy saving, emission reduction, and green environmental protection are also the development direction of construction machinery. In recent years, my country's construction machinery industry has gradually attached importance to environmental protection and sustainable development strategies in product research and development. At present, the transmission mode of the loader is hydraulic transmission and power shifting, and the hydraulic torque converter used has the problems of low transmission efficiency at low speed and high engine emissions. [0003] Because the hybrid transmission is not limited by the power of the power battery, and has a good effect of energy saving and emission reduction, it has a practical application prospect on the l...
