Abstract
The utility model discloses a heat dissipation control by temperature change fan clutch, include: the hollow rotating shaft and the fan blade set casing body, the fixed casing cover of fan blade is established on the hollow rotating shaft, be provided with the first bearing that corresponds with the fixed casing of fan blade on the hollow rotating shaft, the hollow rotating shaft front end is provided with hollow threaded rod, the rear end of the fixed casing of fan blade is provided with the cover and establishes the clutch friction plate on the hollow rotating shaft, set up and the corresponding bimetallic strip of clutch friction plate on the hollow rotating shaft, be provided with the fin on the terminal surface of the fixed casing of fan blade. In this way, heat dissipation control by temperature change fan clutch, radiating effect when utilizing the fin to promote the fixed casing of fan blade and rotate, the air current passes through hollow threaded rod and gets into the fixed casing of fan blade, to the bimetallic strip heating, bimetallic strip the thermal expansion and being out of shape gradually finally makes fixed casing of fan blade and hollow rotating shaft run -in synchronism, the temperature control sensitivity is good.
Description
Technical field
This utility model relates to clutch field, particularly relates to a kind of heat radiation temperature-controlled fan clutch.
Background technology
Silicon oil filled fan clutch is mainly used on automobile, and in the process of moving, due to the change of environmental condition and operating condition, the thermal conditions of electromotor is also changing automobile, it is necessary to regulate the intensity of cooling of electromotor at any time.During the broiling summer, electromotor is at low speed, big working under load, the temperature of coolant is significantly high, fan should high speed rotating to increase cooling air quantity, strengthen the heat-sinking capability of radiator, and in cold winter, when coolant temperature is relatively low, or when galloping has powerful head-on wind to blow over radiator, fan works on and just becomes meaningless, not only consumption of engine power in vain, but also produces very big noise, therefore, at any time its intensity of cooling is regulated according to the thermal conditions of electromotor and just seemed particularly significant.
In order to realize the Intelligent adjustment with radiator temperature of fan, can between blower pulley and cooling fan device silicon oil filled fan clutch, and the structure of silicon oil filled fan clutch is complicated, and the sealing in order to promote silicone oil also to add sealing member, poor radiation, it is necessary to improvement.
Utility model content
This utility model is mainly solving the technical problems that provide one heat radiation temperature-controlled fan clutch, heat radiation performance and temperature control clutch effect.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide one heat radiation temperature-controlled fan clutch, including: hollow rotating shaft and the fixing housing of fan blade, the fixing housing of described fan blade is set on hollow rotating shaft, described hollow rotating shaft is provided with the clutch shaft bearing corresponding with the fixing housing of fan blade, described hollow rotating shaft front end is provided with hollow thread bar, the rear end of the fixing housing of described fan blade is provided with the clutch friction plate being set on hollow rotating shaft, described hollow rotating shaft arranges the bimetal leaf corresponding with clutch friction plate, the end face of the fixing housing of described fan blade is provided with fin.
In one preferred embodiment of this utility model, described hollow thread bar being arranged with second bearing being positioned at the fixing housing forward end of fan blade, described second bearing arranged outside has fixing nut.
In one preferred embodiment of this utility model, described hollow rotating shaft is hollow structure, and one end of described bimetal leaf extends to the inwall of hollow rotating shaft.
In one preferred embodiment of this utility model, described clutch friction plate is densely covered with micropore.
In one preferred embodiment of this utility model, described hollow rotating shaft and hollow thread bar are integrated.
The beneficial effects of the utility model are: the one heat radiation temperature-controlled fan clutch that this utility model is pointed out, radiating effect when utilizing fin to improve the fixing housing into rotation of fan blade, air-flow enters the fixing housing of fan blade by hollow thread bar, bimetal leaf is heated, bimetal leaf expanded by heating and deform gradually, reducing the gap with clutch friction plate, finally make the fixing housing of fan blade and hollow rotating shaft run-in synchronism, it is good that temperature controls susceptiveness.
Accompanying drawing explanation
