Problems solved by technology

Therefore, the magnetic force of the electromagnet cannot be effectively transmitted to the armature
In addition, additional electromagnetic force is required to attract the armature, so the size and weight of the magnet are increased
Accordingly, there is a problem that the fan clutch device cannot achieve the required compactness, light weight, and large power accumulation
In addition, when the armature is located in a position separated from a shaft in the oil reservoir, there is also the following disadvantage: since the armature is always located in the oil during the fan rotation, the operation of the armature, that is, the valve Deterioration of the opening and closing operation of the element

Embodiment Construction

[0028] In the present invention, FIG. 1 shows an external control type fan clutch device, a sealed housing 2 is composed of a box body 2-1 and a cover body 2-2 and is supported by a rotating shaft (drive shaft) 1, Wherein the rotating shaft body (drive shaft) 1 is driven by a drive part (motor) via a bearing 13 . The interior of the sealed housing is divided into an oil storage chamber 5 and a torque transmission chamber 6 by a partition plate 4 , wherein the partition plate 4 has an oil supply adjustment hole 8 . A driving disc 3 is fixedly connected to the end of the rotating shaft body 1 and located in the torque transmission chamber 6, so as to form a torque transmission gap between the driving disc 3 and the inner peripheral surface of the torque transmission chamber.

[0029] A baffle 15 is provided on a portion of the inner peripheral wall surface of the cover body 2-2 opposite to the outer peripheral wall portion of the drive plate 3 to collect and store oil during rot...

Abstract

The invention provides a control method of an external control type fan clutch able to improve engine performance, fuel cost and cooling performance of a capacitor of an air conditioner (A / C) and restrain fan noises due to associative rotation. Namely, in the external control type fan clutch device constructed so as to control the opening and closing of a supply adjusting hole of oil by a valve member operated by an electromagnet, the opening and closing of the supply adjusting hole of the oil is on-off-controlled with the temperature of a cooling liquid of a radiator, a fan rotating speed, the temperature of transmission oil, a vehicle speed, an engine rotating speed, the pressure of a compressor of the air conditioner, etc. as parameters.

Description

technical field [0001] The present application generally relates generally to a control method of an externally controlled fan clutch in a system in which rotation of a fan for cooling an engine in an automobile or the like is controlled according to changes in temperature of the external environment and changes in driving conditions. Background technique [0002] In this type of fan clutch, the interior of the sealed chamber composed of a box body and a cover body is divided into an oil storage chamber and a torque transmission chamber by a partition plate, and a drive disc is installed inside the torque transmission chamber, which is divided into There is an oil supply adjustment hole on the separator. A baffle for collecting and storing oil while rotating is formed on an inner peripheral wall surface of the sealing case opposite to an outer peripheral wall portion of the drive plate. Through the torque transmission chamber, a circulation flow passage is formed between th...
