Abstract

The invention discloses a hydraulic auxiliary driving system with energy recovery and speed slowing functions. The hydraulic auxiliary driving system comprises a controller, an engine, a power takeoff, a hydraulic pump / motor, a hydraulic control valve bank, an energy accumulator, a pressure indicator, a hydraulic oil tank and the like, wherein the hydraulic pump / motor is connected to a PTO port of the engine by a rotating shaft through a flange; the hydraulic pump / motor, the hydraulic control valve bank, the energy accumulator and the oil tank form a hydraulic loop; and the hydraulic pump / motor is connected to the hydraulic oil tank by the hydraulic control valve bank and the energy accumulator. According to the system, the driving force of the whole vehicle on an upward slope is improved, and power is supplied during vehicle starting; energy recovery is realized during vehicle braking; an effect of a retarder is achieved; and the running economical efficiency of the whole vehicle can be favorably improved by a proper control strategy.

Description

technical field [0001] The invention relates to an energy recovery system, which belongs to the technical field of automobile hydraulic application, and specifically relates to a system and method capable of realizing hydraulic auxiliary drive and energy recovery. Background technique [0002] In recent years, my country has entered a high-incidence period of severe weather dominated by fog and haze, especially in winter and spring. are under severe pollution. Haze weather seriously damages people's respiratory system, and people's health is seriously threatened in such an environment for a long time. [0003] After research, the main causes of smog are the excessive combustion of coal and vehicle exhaust emissions, among which motor vehicle exhaust emissions occupy an important position. In order to alleviate environmental pressure and purify the air, the state has introduced various measures to deal with extreme weather such as smog. Among them, the development of hybrid...
