Abstract

The invention discloses a gearbox oil supply and lubrication system. The gearbox oil supply and lubrication system comprises an oil pool, a high-pressure loop and a lubricating loop, wherein the high-pressure loop comprises a first electronic oil pump, an energy accumulator and a first actuator, an oil inlet of the first electronic oil pump communicates with an oil pool pipeline, an oil outlet ofthe first electronic oil pump communicates with an opening of the energy accumulator and an oil inlet pipeline of the first actuator, and an opening of the energy accumulator communicates with the oilinlet pipeline of the first actuator; the lubricating loop comprises a second electronic oil pump and a second actuator, an oil inlet of the second electronic oil pump communicates with the oil poolpipeline, a main pipeline and a bypass pipeline are arranged between an oil outlet of the second electronic oil pump and an oil inlet of the second actuator, a cooling device is arranged on the main pipeline, and a first one-way valve is arranged on the bypass pipeline; and the first electronic oil pump and the second electronic oil pump share one driving piece. According to the system, by means of the high-pressure loop and the lubricating loop, the integration level is improved, and the accuracy of oil supply is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a gearbox oil supply and lubrication system. Background technique [0002] In existing vehicles, the gearbox oil supply and lubrication system mostly adopts a single mechanical or a double-pump oil supply system consisting of an electronic pump and a mechanical pump. Among them, the single mechanical pump is usually driven by the engine, and the pump oil of the mechanical pump is adjusted according to the engine speed, but the engine speed cannot be controlled freely, the working efficiency of the mechanical pump is low at low speed, and the flow rate is greater than the demand at high speed, resulting in waste; The oil needs to meet the driving and cooling lubrication needs of the actuator at the same time, resulting in a complex structure of the hydraulic control system and lubrication system, many parts, and high cost. A dual-pump system consisting of an electro...
