Pneumatic silicone oil fan clutch capable of automatically adjusting rotating speed

Abstract

The invention discloses a pneumatic silicone oil fan clutch capable of automatically adjusting rotating speed. The clutch comprises a driving shaft, a driving plate, a shell, a cover body, a driven plate and a cylinder piston assembly, wherein the cylinder piston assembly is arranged on the cover body; the driving plate is provided with an oil outlet, one end of the driven plate is fixedly connected to the driving plate, and the other end of the driven plate is opposite to the oil outlet and can block the oil outlet; the air cylinder piston assembly comprises an air cylinder, a piston output assembly, an intake throttle valve and an exhaust throttle valve, one end of the piston output assembly is hermetically connected with the air cylinder, the other end of the piston output assembly extends out of the air cylinder and aligns to the driven plate, and the air cylinder is provided with an intake regulating valve and an exhaust regulating valve; and the intake throttle valve and the exhaust throttle valve are connected with a gas throttle controller correspondingly, and the gas throttle controller is electrically connected with an ECU of an automobile or an engine. According to the clutch, the problems of control lag or advance and the like caused by the influence of system layout when a thermosensitive bimetal temperature sensor in a traditional clutch senses the temperature ofan air field around a water tank can be avoided, and the control accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of clutches, in particular to a silicone oil fan clutch. Background technique [0002] During the driving process of the car, due to the change of environmental conditions and operating conditions, the thermal condition of the engine is also changing. The water temperature for the normal operation of the engine is 80-90°C. As the working conditions change, the strength of the cooling system must be changed accordingly to ensure that the engine works at a normal temperature. When the engine is working under heavy load and the water temperature of the coolant is high, the fan speeds up to increase the heat dissipation intensity of the cooling system; noise. The silicone oil fan clutch is an important part of the engine cooling system. The temperature-controlled silicone oil clutch senses the airflow temperature of the coolant through the temperature-sensing sheet. The temperature-sensing sheet deforms after ...
