Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clutch device or a fan clutch device for adjusting the distance of a permanent magnet coupling,

The present invention relates to a shift clutch device or a fan clutch device having a permanent magnet coupling for a variable torque clutch of a general industrial transmission device and a multi-plate clutch, a low-noise permanent magnet couple for controlling rotation of a cooling fan applied to an internal combustion engine for a vehicle The present invention relates to a shift clutch device or a fan clutch device having a ring and a multi-plate clutch.

A magnet type fan clutch device constituted by incorporating a magnetic coupling and an electromagnetic clutch has already been proposed as a fan clutch for controlling the rotation of a cooling fan (hereinafter simply referred to as a fan) applied to an internal combustion engine such as a vehicle JP-A-2002-195303, etc.). In this type of magnet type fan clutch device, the magnetic coupling and the electromagnetic clutch are combined with each other, and the fan is attached to the magnet coupling side. Specifically, for example, a magnetic-type fan clutch device is constituted by a rotatable electromagnetic clutch and a magnet coupling, and the electromagnetic clutch includes an armature and a clutch rotor in which a magnetizing coil is supported by a drive shaft or a stationary shaft Wherein the magnetic coupling is composed of a permanent magnet rotating body for attaching a fan to the outer periphery thereof and a hysteresis material or a conductor disposed so as to face the permanent magnet with a slight gap therebetween. The magnetic coupling is configured such that the permanent magnet rotating body and the disk rotate integrally by an attractive force between the permanent magnet and the hysteresis material or the conductor. Such a magnet type fan clutch device is configured to control the operation of the magnetic coupling so that the magnetic coupling is turned on / off by the electromagnetic clutch.

In the case of the magnetic-type fan clutch device of such a configuration, when the magnetizing coils of the electromagnetic clutch are turned on, the armature is attracted to the rotor by the clutch rotor, and the clutch rotor, armature and disk, And rotates integrally to rotate by the magnet coupling. Therefore, the following excellent effects and the like can be obtained. In other words, the rotation of the fan can be controlled by turning the electromagnetic clutch on / off. Further, since the on / off of the electromagnetic clutch is controlled in relation to the temperature of the cooling water, the throttle aperture, the rotational speed of the engine, and the air conditioner switch, the rotation of the fan can be accurately and stably controlled. Furthermore, when the fan is rotated by the magnet coupling, the magnetic coupling transmits the rotation torque by the magnetic force of the permanent magnet, and the magnetic coupling slips and cushion start is performed. Therefore, when the electromagnetic clutch starts to be turned on, the load is small and the noise of the fan can be remarkably reduced as compared with the fan clutch device without the magnetic coupling.

However, in the conventional magnet type fan clutch device, the magnetic coupling is composed of the permanent magnet rotating body and the permanent magnet mounted on the rotating body, so that the magnetic flux direction of the permanent magnet and the electromagnetic clutch can not be switched and controlled . Therefore, the conventional magnet type fan clutch device has a disadvantage that the rotational speed of the fan can not be arbitrarily changed.

Accordingly, it is an object of the present invention to provide a clutch device or a fan clutch device that is small, light, and inexpensive.

Another object of the present invention is to provide a clutch device or a fan clutch device capable of changing the rotational speed of an output shaft of a fan or the like by controlling a magnetic coupling and a multi-plate clutch.

Another object of the present invention is to provide a clutch device or a fan clutch device which is configured to deliver a reduced speed even when it is impossible to control due to a problem in electric or hydraulic pressure lines, thereby solving the problems of the above-mentioned prior art.

And a conductor or hysteresis material attached to the disk so as to face the permanent magnet with a slight gap between the magnet and the permanent magnet,

The shift clutch or cooling fan clutch of the present invention

A drive shaft rotatably supported by the housing; An output shaft rotatably installed on a coaxial line of the drive shaft; A permanent magnet rotating body having a permanent magnet; An eddy rotating plate having a conductor or hysteresis material adhered to the permanent magnet rotating body so as to face the permanent magnet rotating body with a slight clearance therebetween; The permanent magnet rotating body and the eddy rotating plate are divided into a driving shaft and an output shaft, respectively, and rotate together with the shaft.

The magnetic coupling is configured to integrally rotate the permanent magnet rotating body and the disk by the attraction force between the permanent magnet and the conductor or the hysteresis material. When the rotation speed becomes equal to or higher than a predetermined number of revolutions, A deceleration state in which the vehicle is decelerated at a constant rate, and a direct-coupled two-speed transmission connected to the multi-plate clutch.

And a gap between the eddy rotating plate and the permanent magnet rotating body is configured to be widened in the axial direction, and is controlled by an actuator.

The attractive force of the magnetic coupling is inversely proportional to the square of the gap. Therefore, if the distance exceeds a certain distance, it can not function as a coupling and is separated. Therefore, it is possible to add a state in which no power is transmitted, so that a three-speed transmission can be performed.

In addition, the multi-plate clutch includes a plurality of inner disks and a plurality of outer disks, which are disposed on the drive shaft and the output shaft, respectively, and are rotatably coupled with each other, .

The actuator may also be located in the housing, where the actuator and the magnetic coupling or actuator and the multi-plate clutch are coupled by a thrust bearing.

Also, the actuator may be located on a drive shaft or an output shaft. In this case, since the actuator driving source must be supplied to the cylinder through the rotating shaft in the housing, a rotary type contact or a connector should be used.

The actuator may also be a hydraulic or pneumatic cylinder. In recent years, many pneumatic or hydraulic devices are mounted on the vehicle, so it is easy to use a pneumo-hydraulic device without installing a separate hydraulic pump.

Further, the actuator may be a motor-driven shift clutch or a cooling fan clutch

One of the actuators is a change-speed clutch or a cooling fan clutch which is operated to separate the multi-plate clutch or the magnetic coupling,

Wherein the plurality of permanent magnets mounted on the permanent magnet rotating body are equally arranged in the circumferential direction,

Wherein a plurality of permanent magnets mounted on the permanent magnet rotating body are set so as to have a plurality of poles evenly in the circumferential direction and the magnetic loop elements are arranged on the inner circumferential side and the outer circumferential side of each of the S pole and the N pole in the circumferential direction Alternately assembled Transmission clutch or cooling fan clutch

The device according to the present invention can be applied not only as a variable torque clutch of a machine having a general purpose but also as a magnet type clutch device or a magnet type fan clutch device for a variable torque clutch of a general industrial transmission device, A magnet type clutch device or a magnet type fan clutch device for controlling the rotation of the cooling fan applied to the internal combustion engine of the engine.

It is cheaper and lighter than the electromagnetic clutch type, and the energy consumption for the electromagnetic clutch operation is drastically reduced.

Even if the control is not possible, it is possible to set the connection to the deceleration state or the direct connection state so that it can have safety measures.
