Abstract

PROBLEM TO BE SOLVED: To engage/disengage a clutch smoothly and surely by releasing the connection of first/second clutch plates by pulling a wire. SOLUTION: When a pulley 7 is rotated by a motor, the link 5 of a rotation torque output side is rotated by the connection of clutch plates 5, 8 and a steering system connected to the rotation torque output side link 6 is driven. When the wire 13 is pulled manually in an arrow mark direction, the second clutch plate 8 is moved in the arrow mark direction through a pin 14 and the engaged state of the clutch plates 5, 8 is released and the necessary operation of the steering system is carried out and thereafter, the pulling of the wire 13 by a hand is released. Thereby, the clutch plates 5, 8 are engaged by the return operation of a spring 11 and the clutch can be turned on smoothly and surely.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical clutch structure and, more particularly, to a novel improvement for smoothly and reliably engaging and disengaging a clutch by moving a clutch plate provided on a torque input side with a wire. .

[0002]

2. Description of the Related Art Although not shown, a mechanical clutch structure in a torque transmission device used in such an aircraft or the like which has been conventionally used is provided with a slip clutch on an electric drive side and manually releases the torque transmission. In this case, the wire is operated by applying a force higher than the slip clutch.

[0003]

Since the conventional mechanical clutch structure is constructed as described above, there are the following problems. In other words, when operating the steering system on an aircraft or the like, it is generally desirable to operate the steering system with a light operating force from the viewpoint of the safety of the operation of the aircraft or the like. In a state where operation cannot be performed without adding the steering wheel, a heavy burden is imposed on the operator, and there has been a long-awaited desire to be able to perform steering more easily and with less burden.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. In particular, the clutch plate provided on the torque input side is moved by a wire to smoothly and reliably engage and disengage the clutch. It is an object to provide a mechanical clutch structure as described above.

[0005]

A mechanical clutch structure according to the present invention comprises a support shaft rotatably provided on a support member, and a first shaft connected to a rotational torque output side link and rotatably provided on the support shaft. A clutch plate, a second clutch plate fixed to the support shaft, a receiver provided on the second clutch plate via a bearing, a spring provided between the support member and the receiver, A wire provided at one end thereof in a gap formed in the support shaft, and a pin provided at the one end and engaging with the second clutch plate. The second clutch plate is formed by pulling the wire. The connection of the first clutch plate is released.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a mechanical clutch structure according to the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a support shaft rotatably supported by a pair of support members 2 and 3, and a first clutch plate 5 is supported on the support shaft 1 via a support shaft bearing 4. The first clutch plate 5 is rotatably provided, and a rotation torque output side link 6 as a torque output side is connected to the first clutch plate 5.

A second clutch plate 8 having a pulley 7 on the torque input side, which is provided to be able to freely contact and separate from the first clutch plate 5, is fixedly provided on the support shaft 1.
On the clutch plate 8, a ring-shaped receiving body 10 is provided coaxially with the support shaft 1 via a bearing 9. A spring 11 as a return spring made of an elastic body is interposed between the receiving body 10 and the support member 2, and the second clutch plate 8 is constantly urged against the first clutch plate 5.

The support shaft 1 is formed in a cylindrical shape, and one end 13a of a flexible wire 13 is provided in a gap 12 formed in the support shaft 1, and is provided at the one end 13a. The pin 14 is in contact with the second clutch plate 8.

Next, the operation will be described. First, in the state of FIG. 1, when the pulley 7 is rotated by an electric motor (not shown), since the clutch plates 5 and 8 are connected, the rotational torque output side link 5 rotates, and the rotational torque output side link 5 rotates. 6, a steering system (not shown) can be driven. In this state, when the wire 13 is manually pulled in the direction of arrow A, the second clutch plate 8
Moves in the direction of arrow A, the contact state of the clutch plates 5 and 8 is released, the necessary operation of the steering system is performed, and then, when the manual pulling of the wire 13 is released, the spring 11
The clutch plates 5 and 8 are joined by the return operation of, and the clutch is turned on again.

[0010]

Since the mechanical clutch structure according to the present invention is constructed as described above, the following effects can be obtained. That is, a clutch is provided on the torque input side, which is an output transmission example of an actuator such as an electric motor, and the clutch can be released simply by pulling one of the clutch plates with a wire, and the operation is performed only by applying an extremely light pulling force. And can greatly contribute to the operation of aircraft and the like.
