Abstract

PURPOSE:To prevent a co-rotation phenomenon by providing a driving disc whose outer peripheral portion ends at a portion in a torque transmission chamber distanced from its outer periphery, and forming torque transmission gaps between an inner face of a body and a side face of the driving disc, and between it and a side face of a partition plate, respectively. CONSTITUTION:A bimetal 10 is bent and a partition plate 7 is energized leftward while being pressurized by a coil spring 22 under a low atmospheric temperature. A side on a torque transmission chamber 9 of the partition plate 7 is largely distanced from a driving disc 2. Oil is sent to an outer peripheral portion 9a in the torque transmission chamber 9 by a centrifugal force, and reserved in the vicinity off an outer peripheral portion 7a of the partition plate 7 and an expansion portion 12c of a diaphragm 12. Since an outer peripheral portion 2a of the driving disc 2 ends at a portion on an inner side of the torque transmission chamber 9 and distanced from the outer peripheral portion 9a, the oil is not present in first and second torque transmittion gaps 16, 17. When the atmospheric temperature increases, the bimetal 10 is almost flat to move the partition plate 7 rightward. The oil is then flowed into the first and second torque transmission gaps 16, 17, the torque is then transmitted from the driving disc 2 to a sealing case 6, and a fan is rotated.

(Prior Art) This type of temperature-sensitive fluid coupling device is described in, for example, Japanese Utility Model Application Publication No. 1-102526, and its typical structure is mounted on a rotary drive shaft with a drive disk (wheel) fixed to the tip. A sealed case is supported through a bearing so as to be relatively rotatable, and the inside of the sealed case is divided by a partition plate into an oil reservoir chamber and a torque transmission chamber. A sealed case with a cooling fan attached to its outer periphery is assembled with a cover and a body that holds the bearing. A bimetal thermosensitive element placed on the outside of the cover side of the sealed case bends and deforms due to temperature changes, and in conjunction with this, the valve member that comes into contact with the piston rod opens the outflow adjustment hole provided in the partition plate. Torque is transmitted by opening and closing and allowing oil to flow from the oil reservoir chamber to the torque transmission chamber.

The temperature detected by the thermosensor is generally the temperature of the air after passing through the radiator. For example, at low temperatures below 60°C, the bimetal becomes almost flat, the valve member closes the outflow adjustment hole, and the coupling is turned off. At high temperatures of 60°C or higher, the bimetal is bent, the valve member separates, the outflow adjustment hole is opened, and the coupling is turned on.

Originally, the role of the fluid coupling device is to keep the fan rotation speed as low as possible at such low temperatures to save warm-up time. Conventional devices have been inadequate in terms of causing this "trailing".

Based on this configuration, according to the present invention, when the temperature sensing element senses the outside temperature and deforms, the deformation is transmitted to the partition plate via the piston rod, and the partition plate moves while deforming the diaphragm, thereby generating torque. Approaching or moving away from the drive disk in the transmission chamber. When the partition plate approaches the drive disk,
The torque transmission gap between both sides is appropriately narrowed, and at the same time, the oil pushed out by the deformation of the diaphragm is applied to the torque transmission gap, so that torque is transmitted by the viscous resistance of the oil. Therefore, the force/twisting is in the ON state. When the partition plate separates from the drive disk, oil in the torque transmission gap collects radially outward, reducing viscous resistance and no longer transmitting torque. Therefore, the coupling is O
It becomes FF state.

The outer periphery of the drive disk terminates inside the torque transmission chamber, away from the outer periphery, so the coupling is turned off.
In this state, the oil in the torque transmission chamber is pushed further outward than the outer end of the drive disk by centrifugal force.
Since there is almost no oil in the torque transmission gap, so-called "wristing" hardly occurs.

In addition to bimetal, thermowax or the like can also be used as the temperature sensitive body.
