Description
Technical Field
The invention relates to the technical field of automobile cooling and lubricating systems, in particular to a vehicle cooling and lubricating system, a control method and an electric control system.
Background
An automatic transmission is a device that shifts a gear to an appropriate shift gear according to a running state of a vehicle. An automatic transmission generally includes at least one planetary gear set having a sun gear, an inner periphery, and a carrier as operating members, and an operating element for controlling the operating members, such as a friction plate assembly of a clutch and a brake, and the like. In addition, the automatic transmission further includes a hydraulic control system for roll control of the friction plate assembly, and the clutch and the brake are controlled to be engaged or disengaged according to each shift stage by operation of the hydraulic control system, thereby achieving each shift stage. The clutch of the friction member transmits power of the engine to or between the operating members of the planetary gear set, and the clutch may be used to transmit power in various machines as well as an automatic transmission. The oil way of the traditional gearbox has two functions, (1) hydraulic control; (2) lubrication of bearings, gears, etc. The current oil way design realizes hydraulic control and lubrication simultaneously in the same oil supply system, and usually gear surface lubrication is realized by stirring oil and splashing lubrication of gears in an oil collecting box. If the oil temperature is higher, the viscosity of engine oil is reduced, and the problems of difficult oil pressure establishment and the like are easy to occur, so that the cooling system for the oil path inherently needs to cool the oil path, and the hydraulic control part can effectively establish the oil pressure to realize the control action. The electric drive assembly is characterized in that a motor and other mixed components are added on the basis of an automatic gearbox, and various conversions among an engine, a generator and an output shaft are carried out through the combination or disconnection of a single or a plurality of planetary gear sets and a single or a plurality of clutches. Wherein the motor belongs to the part that calorific capacity is big, need carry out effective cooling in order to guarantee its long-term steady operation. The oil circuit in the electric drive assembly has three roles, including: (1) hydraulic control of the clutch; (2) lubrication of bearing gears and the like; (3) cooling of components such as a motor. In the current oil way design system, part of oil passes through an electronic pump and is led to a hydraulic control system of a clutch, and the oil flows back to an oil collecting box through a pressure relief valve during pressure relief; and the other part of oil passes through the electronic pump and then passes through the external cooling module, so that the oil temperature is reduced and then is sent to all cooling and lubrication required parts through the oil way. In the oil circuit design system, oil liquid can be conveyed to parts needing lubrication only after passing through the cooling module. However, cooling and lubrication systems differ in their requirements for oil temperature, and generally require lower oil temperatures at the time of cooling demand to achieve good cooling; when the lubrication is needed, a higher oil temperature is generally needed, and if the oil temperature is too low, the viscosity of the oil is higher, so that the friction loss is increased.
