Abstract

The invention provides a single-pump double-power-source hydraulic oil pump which can be integrated in the axial direction of a vehicle and comprises a motor, a one-way clutch, an input shaft, an oil pump outlet, an oil pump and an oil pump inlet. Wherein rotors of the pair of motors are respectively connected with the engine input shaft through the one-way clutch, the oil pump input shaft is connected with the rotors of the pair of motors, and the oil pump is provided with an oil pump outlet and an oil pump inlet. The one-way clutch device is adopted, a single-pump double-power-source scheme integrating two motors is innovatively provided, the problems that a traditional double-pump double-power-source scheme is low in integration level and large in size space, and an auxiliary electric pump cannot work continuously are effectively solved, and the working condition requirements of vehicle trailer starting, trailer driving, pure electric starting and the like are effectively met.

Description

technical field [0001] The invention relates to a hydraulic oil supply device, in particular to a single pump dual power source hydraulic oil pump. Background technique [0002] In vehicle transmissions with hydraulic systems such as wet clutches, hydraulic transmission elements, pressure lubrication, etc., an oil pump is required to suck out the oil from the oil pan to provide the wet clutch with closing and unlocking control pressure with a specified oil supply flow and pressure. , provide transmission power medium for hydraulic components, and provide lubrication and heat dissipation for gears, shafts, bearings, friction plates, etc. [0003] In the working conditions such as the vehicle needs to start the trailer, the trailer runs when the power is lost, the pure electric start of the new energy vehicle, etc., since the traditional vehicle transmission oil pump only starts to work when the engine is started, it cannot meet the needs of the above working conditions and ne...
