Description

Technical Field

[0001] The present application relates to the technical field of fan clutches, and in particular to a valve plate assembly of a fan clutch. Background Art

[0002] The fan clutch is an auxiliary cooling device of the vehicle, which is used in the cooling system of the vehicle. When the vehicle is driving, the thermal condition of the engine is changing due to changes in environmental conditions and operating conditions. Therefore, the cooling intensity of the engine must be adjusted at any time. Installing a silicone oil fan clutch between the fan pulley and the cooling fan is one of the methods to achieve this adjustment. The silicone oil fan clutch uses silicone oil as a medium and uses the high viscosity of silicone oil to transmit torque. The fan speed is collected by the speed sensor and the information is sent to the ECU. The ECU sends instructions to the solenoid valve, which controls the valve plate switch and then controls the fan speed.

[0003] At present, the valve plate assembly of the common electronically controlled silicone oil fan clutch is connected by riveting. The riveting connection method can improve the loosening of the valve plate assembly during operation to a certain extent, but the valve plate assembly is also more likely to deform during riveting.

Since the structures of the first clamping plate 21 and the second clamping plate 22 are consistent, in this embodiment, the first clamping plate 21 is taken as an example for description, and the end face of the positioning portion 11 abutting against the first clamping plate 21 is set as the lower end face of the positioning portion 11, and the end face of the first clamping plate 21 abutting against the positioning portion 11 is the upper end face of the first clamping plate 21.

[0039] Reference Figure 2 and Figure 3 A mounting groove 211 is provided at one end surface where the first clamping plate 21 abuts against the positioning portion 11, and a plurality of equally spaced positioning grooves 212 are integrally formed at the bottom of the mounting groove 211. The height of the positioning groove 212 is lower than the height of the mounting groove 211. In this embodiment, according to the size of the mounting groove 211 and the specific situation, four equally spaced positioning grooves 212 are preferably provided in the mounting groove 211.

[0040] Reference Figure 3 and Figure 4 An elastic support member 2121 is built into the positioning groove 212. In order for the elastic support member 2121 to play a buffering role on the positioning portion 11, the elastic support member 2121 is protruded from the mounting groove 211. In order for the staff to place the elastic support member 2121 in the positioning groove 212 conveniently, a first chamfer 2122 is provided at the edge of the groove of the positioning groove 212.
