Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an actuation force transmission device, and more specifically, to a control device that can transmit an actuation force to a transmission element no matter which one of a plurality of control elements is actuated. The present invention relates to an actuating force transmitting device used by being inserted between an element and a transmitting element.

Conventionally, in a device that drives and controls a controlled element, which is a certain control element, using a transmission element, when several systems of control elements are added and any control element attempts to drive and control the controlled element, teeth,
As many transmission elements as the number of added control elements are required to connect the control elements and the controlled elements, there is a drawback that the apparatus becomes complicated and the cost increases.

As a means to improve the above-mentioned drawbacks,
The prior art disclosed in Publication No. 165324 states that during normal driving, the throttle valve is controlled by the accelerator pedal;
A device is disclosed in which a constant speed traveling device controls a check valve when traveling at a constant speed on an expressway. The device described in this publication has a cylindrical slider with an arm on its body that engages with an operating wire, which is slidably fitted into a guide inside the device body. A wire is fixed, and the operating wire is slidably inserted into a hole provided at the other end and an arm attached to a slider. The operation wire is configured such that a sphere having a diameter larger than the diameter of the hole is attached to the tip of the operation wire to prevent it from coming out of the hole.

Therefore, when one operating wire is pulled and the hole and the sphere engage, the slider follows the wire and drives the actuated wire. Meanwhile, the holes inserted into the wires on the non-moving side simply slide over the wires and do not interfere with each other. However, this prior art has the disadvantage that the overall length of the device increases because the stroke length of the slider requires the required stroke length of the operated wire.

Further, Japanese Utility Model Application Publication No. 55-62422 discloses a device for controlling a throttle lever of an internal combustion engine using an accelerator pedal and an accelerator pedal holding lever. This device is mounted on a hydraulically driven vehicle that drives a hydraulic pump using the internal combustion engine and is driven by a hydraulic motor operated by hydraulic pressure supplied by the hydraulic pump. The operating wire connected to the accelerator pedal and the operating wire connected to the holding lever are connected to pins slidably attached to two arc-shaped elongated holes provided in the arm linked to the throttle lever. An actuation force transmission device engaged with each is disclosed. This device also requires an elongated hole that is longer than the stroke length of the actuated rod, so there is a problem in that the actuating force transmission device cannot be made compact.

[Purpose of the invention]

The present invention has been made by focusing on the above problems, and it is possible to transmit operating force to a single controlled element by a plurality of control elements with high efficiency, downsize, and furthermore, each wire The object of the present invention is to provide an actuating force transmission device that can increase the degree of freedom in layout.
