Abstract

The invention relates to an electromagnetic torsional spring type clutch, a switch water pump based on the electromagnetic torsional spring type clutch and a vehicle. The electromagnetic torsion spring type clutch comprises a driving wheel assembly, a driven wheel assembly and a control device, wherein the driving wheel assembly and the driven wheel assembly are connected through a bearing, and relative rotation can be achieved between the driving wheel assembly and the driven wheel assembly; a friction sleeve is arranged outside a support in the driving wheel assembly and is tightly clamped with a spiral part of a torsional spring in the driven wheel assembly; the switch water pump comprises the electromagnetic torsional spring type clutch, an iron core assembly and a pump body assembly;and by means of connection or disconnection between a coil and a power supply, a power output part of the clutch part is controlled to transmit the rotary motion to an impeller or not so as to controlthe motion of the impeller. According to the switch water pump based on the electromagnetic torsional spring type clutch, the problem that the torsional spring is abraded too fast is solved, and a device in which a cooling system of an engine is controlled to work according to the temperature of the automobile engine is formed.

Description

technical field [0001] The invention belongs to the technical field of water pumps mounted on automobile engines, in particular to an on-off water pump based on an electromagnetic torsion spring clutch. Background technique [0002] The car engine water pump is an important part of the engine cooling system. The function of the car engine water pump is to pump the coolant, so that the coolant flows quickly in the cooling water channel of the engine, so as to take away the heat generated by the engine when it is working, and keep the engine normal. Working temperature, at present, the current status of automotive engine water pump products is that centrifugal water pumps are widely used as the main component of the forced circulation of the cooling system. The water pump on the car engine mainly uses a belt to drive the pulley. The pulley directly drives the impeller of the water pump. The impeller makes the coolant flow and dissipates heat for the engine. [0003] There are...
