Abstract

The invention relates to a controllable driving device for an engine. The controllable driving device for the engine is applied to a water pump of an automotive engine. The controllable driving devicefor the engine comprises a main shaft. A driven portion and a driving portion are installed on the main shaft, and at least one coupled region exists between the driving portion and the driven portion and transmits the force moment between the driving portion and the driven portion. The coupled regions are filled with adhesive liquid, and the filling amount of the adhesive liquid in the coupled regions is controlled in the mode that at least one pneumatic actuator changes the intake pressure. The controllable driving device for the engine adopts the pneumatic actuators, is low in driving power and saves more energy; an electromagnetic valve which is directly installed on the water pump is omitted, and the structure is more compact; the number of parts is reduced, the reliability is higher; and the adhesive liquid inside an adhesive clutch can be replaced and maintained, and the service life of the clutch is prolonged.

Description

technical field [0001] The invention relates to a controllable driving device for a locomotive, which is suitable for a cooling water pump of an automobile engine system. Background technique [0002] The water pump commonly used in the domestic commercial vehicle market is a mechanical cooling water pump. The mechanical water pump is driven by the engine pulley, and the flow rate of the coolant depends on the engine speed. However, the engine speed and load are not in a linear relationship, which makes the coolant flow output by the water pump not match the cooling demand of the engine when it is actually running, and finally makes the engine often work under insufficient cooling or overcooling, resulting in overheating of the water pump. More energy consumption and reduced engine efficiency. [0003] In foreign countries, the engine cooling water pump of commercial vehicles has been upgraded from a mechanical cooling water pump to an electromagnetic silicon oil clutch wat...
