Embodiment Construction

[0028] As mentioned in the background art, in the prior art, the configuration of multiple clutches and multiple cooling systems leads to a complex power system of the vehicle and increased costs; meanwhile, due to the separation of the power oil circuit and the cooling oil circuit, the energy consumption of the system increases.

[0029] The technical solution of the present invention is based on the working mechanism of the power system, and integrates the gearbox and the cooling unit to simultaneously satisfy the power and cooling control of the gearbox in the power system. At the same time, a large-displacement low-pressure oil pump and a small-displacement high-pressure oil pump are used to realize the functions of cooling and lubrication and gearbox control respectively, so as to provide flow on demand and reduce system energy consumption. Especially for a hybrid vehicle, compared with the prior art in which a hybrid control unit and a cooling unit are separately provided...

Abstract

The invention discloses a power system and a vehicle. The power system comprises a transmission case, a motor, a high-pressure oil pump, a low-pressure oil pump and a reversing valve, wherein the high-pressure oil pump is coupled to the motor and is used for providing a high-pressure oil-way with low-pressure oil; the high-pressure oil-way is used for driving the transmission case; the low-pressure oil pump is coupled to the motor and is provided for providing a low-pressure oil-way with low-pressure oil; the low-pressure oil-way is used for lubricating the transmission case; the reversing valve is used for switching the flow direction of high-pressure oil output from the high-pressure oil pump and the high-pressure oil flows to the high-pressure oil-way or the low-pressure oil-way, wherein the pressure intensity of the low-pressure oil is lower than that of the high-pressure oil; and the high-pressure oil pump is connected with the high-pressure oil-way through the reversing valve. According to the power system and the vehicle, the cost and the energy consumption of the power system are reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle power engineering, in particular to a power system and a vehicle. Background technique [0002] With the development of automobile technology and the popularization of automobiles, the requirements for the performance of vehicles are getting higher and higher. Among them, the power system of the vehicle is a key component of the vehicle. [0003] In the prior art, due to its advantages of flexibility, comfort and uninterrupted power output, the dual-clutch gearbox is widely used in vehicles. In a hybrid vehicle, the engine and the dual-clutch gearbox can also be coupled through a clutch. When the clutch is engaged, the torque output by the engine crankshaft can be transmitted to the dual-clutch gearbox; when the clutch is disconnected, the engine and the dual-clutch gearbox can be cut off. torque transmission between. The clutch driven plate in the dual-clutch gearbox is connected to the input ...
