Abstract

The invention discloses a method of providing oil power steering and control in coordination with the engine oil pump. The emergency steering pump includes a pneumatic clutch and a displacement pump. The pneumatic clutch includes a clutch outer transmission shaft and a clutch inner transmission shaft. The variable displacement pump is provided with a pump shaft. The clutch outer transmission shaft is connected to the gearbox and the clutch inner transmission shaft is connected to the pump shaft, and a clutch disc is provided between the clutch outer transmission shaft and the clutch inner transmission shaft. When the pneumatic clutch is not ventilated, the clutch disc is in a combined state, and the clutch outer transmission shaft and the clutch inner transmission shaft are connected. When the pneumatic clutch is ventilated, the clutch disc is in a disengaged state, and the clutch outer transmission shaft and the clutch inner transmission shaft are disconnected. The invention solves the problem of high fuel consumption, high noise, and the absence of emergency steering device when the traditional automobile or hybrid commercial vehicle runs at high speed.
