Description
Technical Field
The utility model belongs to the technical field of the clutch, concretely relates to automatically controlled silicon oil fan clutch of energy-saving.
Background
The general working principle of the electric control silicone oil fan clutch is as follows: the engine is connected with a driving disc in the clutch and drives the driving disc to rotate along with the engine, after the valve plate mechanism receives a PWM pulse starting signal, the valve plate opens an oil outlet orifice which is communicated with the oil storage cavity and the working groove, silicone oil in the oil storage cavity in the driving disc enters the working groove through the oil outlet through hole under the action of centrifugal force, and the viscous shearing force of the silicone oil drives the clutch driving disc to drive a front cover plate and a rear shell of the clutch to rotate along with the driving disc through the silicone oil, so that a fan fixed on the rear shell is driven to rotate. The more silicone oil is in the labyrinth groove of the working cavity, the larger the torque transmitted by the clutch is, the smaller the slip of the clutch is, the higher the rotating speed of the corresponding fan is, and the larger the air volume is; after the valve plate mechanism receives the PWM pulse closing signal, the valve plate closes the oil outlet, the silicone oil in the oil storage chamber does not enter the working groove any more, and the silicone oil in the working groove flows back to the oil storage cavity through the oil return channel under the action of centrifugal force, so that the silicone oil in the working groove is reduced, the torque transmitted by the clutch is reduced, the slip is increased, the rotating speed of the fan is reduced, and the air volume is reduced.
Generally, when an engine is in a parking state, an oil outlet orifice of an oil storage cavity of an electric control silicone oil clutch is generally in an open state, because the arrangement can ensure that an electric control part does not work when a circuit system of a vehicle fails without electric power, but a silicone oil outlet through hole is opened, silicone oil is in a working state, and a fan is ensured to rotate at a high speed to cool the engine, at the moment, the silicone oil is positioned at the lower part of the oil storage cavity due to the action of gravity, and if the oil outlet orifice is also positioned at the lower part of the oil storage cavity, the silicone oil in the oil storage cavity can flow into a working groove of the clutch from the oil storage cavity through the oil outlet orifice and the oil outlet through hole, after the engine is started in a cold state, the fan is not needed to rotate to cool the engine, but the silicone oil leaked into the working groove when the engine is parked is in the working state of driving the fan to rotate at a high speed, namely, a high-meshing state with a small slip ratio is realized, the engine has low rotating speed, the corresponding clutch driving disc has low rotating speed, silicone oil return power in the clutch working groove is lack, and oil return amount is low, so that engine energy is consumed without end due to oil leakage during parking, and more importantly, the normal preheating time of the engine is prolonged due to unnecessary cold vehicle heat dissipation of the engine, so that cold vehicle abrasion of the engine is increased, energy is consumed without end, energy consumption of a whole vehicle is increased, and the working performance of the engine is also seriously influenced due to prolonged preheating time of the engine.
