Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention will be further described by way of example:

[0023] An automobile fan clutch with a booster mechanism, comprising a drive torque input mechanism, a power transmission mechanism, and a booster mechanism that connects the two and amplifies the force between the two, and is characterized in that the booster mechanism includes Driven disk 16, the driving disk 18 that is arranged opposite to driven disk 16, at least three first grooved fairways 16.1 that are arranged on driven disk 16, at least three roads that are arranged on driving disk 18 and the first grooved fairway 16.1 corresponds to the second grooved fairway 18.1 and the steel ball 17 arranged between them; the groove depths of the first grooved fairway 16.1 and the second grooved fairway 18.1 gradually shrink from the middle to both ends. The electromagnetic clutch type drive torque input mechanism includes a transmission disc 4 pivotally conn...

Abstract

The invention relates to an automobile fan clutch with a force amplifier. The automobile fan clutch comprises a drive torque input mechanism, a power transfer mechanism and a force amplifying mechanism, wherein the force amplifying mechanism is used for connecting the drive torque input mechanism and the power transfer mechanism, and amplifying the acting force between the force drive torque input mechanism and the power transfer mechanism. The automobile fan clutch is characterized in that the force amplifying mechanism comprises a driven plate, a driving plate, at least three first groove lanes, at least three second groove lanes and a steel ball; the driving plate is opposite to the driven plate; the at least three first groove lanes are formed in the driven plate; the at least three second groove lanes are formed in the driving plate and correspond to the first groove lanes; the steel ball is arranged between the first groove lanes and the second groove lanes; the depths of the first groove lanes and the second groove lanes are gradually reduced from the middle part to two ends. Compared with the prior art, the automobile fan clutch has the advantages that the size and calorific value of an electromagnetic coil are greatly reduced, and the weight, volume and calorific value of the product are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an auto fan clutch with a booster mechanism. Background technique [0002] A key component of an automotive thermal management system is the fan clutch. The fan clutch can automatically start and stop according to the water temperature of the engine, reducing the useless power consumption of the fan, and achieving the effects of fuel saving and noise reduction. Another direct advantage over rigid fans is that the warm air is very effective in winter and the cab temperature rises rapidly. In addition, it can reduce cold car wear and prolong engine life. [0003] The Chinese invention patent whose application publication number is CN102606276A discloses a kind of electromagnetic fan clutch, and its driving disc and the suction disc form the friction pair of the clutch parts. Under the action of the magnetic field force, the two attract and transmit torque. The clutch of this ...
