Technical Field

The invention relates to an automobile engine cooling system, in particular to a novel temperature control silicone oil clutch.

Background

The clutch is mounted between the engine and the transmission and is the assembly in the vehicle driveline that is directly associated with the engine. The clutch is usually mounted with the flywheel set of the engine crankshaft and is the part that cuts off and transmits power between the engine and the vehicle drive train. During the whole process of starting the automobile to normally drive, the driver can operate the clutch according to the requirement, so that the engine and the transmission system are temporarily separated or gradually connected, and the power output from the engine to the transmission system is cut off or transmitted. The function of the clutch is to ensure that the engine and the transmission can be gradually jointed, thereby ensuring the smooth starting of the automobile.

With the domestic advancement of the national six-emission standard, the vehicle puts higher requirements on the silicone oil clutch. Such as improved cooling capacity, reduced power consumption, reduced fan noise, etc. However, the traditional silicone oil clutch fan has long separation time and slow response, which easily causes the water temperature of the engine to be incapable of being stably controlled, and causes high water temperature or oil consumption of the engine, high noise of the fan and large impact on a cooling system. Therefore, a silicone oil clutch needs to be designed, and the stepless characteristic and the response time of the clutch are further improved.

The temperature-controlled silicone oil clutch of the prior art comprises: the temperature sensing device comprises a driving shaft, a bearing, a shell, a driving plate, a rectangular sealing ring, a driven plate, a valve block, a temperature sensor, a valve block shaft, an O-shaped sealing ring, silicon oil, an end cover and an oil storage chamber, wherein the oil storage chamber is formed between the driven plate and the end cover between the driving plate and the end cover, the driving shaft transmits power to the driving plate, the driving plate transmits the power to the shell and the end cover through the silicon oil, the temperature sensor is fixed on the end cover, the temperature sensor is connected with the valve block shaft, the valve block shaft is connected with the valve block, when the temperature sensor senses the rise of the temperature of an engine, the valve block shaft drives the valve block to rotate, an oil outlet on the driven plate is opened, the silicon oil transmits the power to the. When the temperature sensor is lowered by the temperature of the engine, the temperature sensor resets to drive the valve plate to rotate, the oil outlet on the driven plate is closed, and meanwhile, the silicone oil returns to the oil storage chamber through the oil return pressure pump and the oil return channel.

The traditional temperature control silicone oil clutch has the advantages that the oil storage chamber and the oil outlet hole are arranged on the end cover, the influence of the rotating speed of a fan is easy to affect, the oil outlet speed is low, and the response capability of the clutch is poor.

As a further preferable mode of the present invention, the driving plate is provided with an oil return pressure pump and an oil return passage, one end of the oil return passage extends into the oil storage chamber, and the other end of the oil return passage extends to the outer edge of the driving plate.

As a further preferable mode of the present invention, the oil return pressure pump, the oil return passage and the oil outlet which are arranged on the active plate are connected and communicated.

As a further preferred aspect of the present invention, the valve plate rotates under the control of the valve plate shaft to open or close the oil outlet on the active plate.

As a further preferred aspect of the present invention, the valve plate is attached to the driving plate and rotates relative to the driving plate.

As a further preferred aspect of the present invention, the temperature sensor is formed by attaching bimetallic strips having different thermal coefficients, and when the temperature sensor is heated, the deformation of the two bimetallic strips changes to control the rotation and the return of the valve piece shaft.

As a further preferred aspect of the present invention, one end of the temperature sensor is fixed to the driving plate through a temperature sensor positioning groove.

As a further preferred aspect of the present invention, the number of said oil outlets is at least 1.

The working principle is as follows: when the temperature sensor senses that the temperature of the engine rises, the temperature sensor is heated to deform to control the valve plate shaft to rotate, so that the valve plate is driven to rotate and the oil outlet hole in the driving plate is opened, silicone oil enters the working cavity through centrifugal force, and the clutch enters a coupling state. When the temperature sensor is subjected to the temperature reduction of the engine, the temperature sensor resets to drive the valve shaft and the valve plate to rotate in the opposite directions and close the oil outlet on the driving plate, meanwhile, the silicone oil returns to the oil storage chamber through the oil return pressure pump and the oil return channel, and the clutch enters a separation state.

Has the advantages that: the novel temperature control silicone oil clutch has the following advantages:

1. by using the clutch with the structure, the oil outlet speed of the clutch is high, and the coupling response time is accelerated by over 70 percent;

2. by using the clutch with the structure, the oil outlet rate of the clutch is stable, and the stepless control capability of the clutch is improved;

3. the clutch with the structure improves the response speed and reduces the overheating risk of the automobile;
