Abstract

PURPOSE:To simplify required operation by providing an apparatus for running a vehicle at a constant speed in which a control shaft connected to a part of an acceleration link mechanism is locked by a locking mechanism for maintaining a constant speed. CONSTITUTION:A pedal arm 2 having an accelerator pedal 1 at its lower end is rotatably supported by an autobody by means of a pin 4 serving as a shaft, through a bracket 3. The arm 2 is extended upwards and a control shaft 7 is connected mutually rotatably to the upper end of the arm by a pin 8. A locking mechanism 11 is privided on the round bar section between the rack tooth 9 and the pin 8 for locking the position of the control shaft 7. An electric motor 23 having a gear 22 engaged with the rack tooth 9 is fixed on the autobody, and an electro-magnetic clutch 24 is mounted in the motor 23. When the lever of a steerig handle is operated, the electromagnetic valve 18 is opened and a pusher 13 is shifted by the actuating force of a hydraulic cylinder 14 to fix the control shaft 7, whereby the accelerator pedal is retained in position and a constant speed traveling can be continued.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a constant speed traveling device for a vehicle that allows a vehicle such as an automobile to travel at a set speed.

Conventionally, when driving a car at a constant speed on a road without traffic lights, such as an expressway or toll road, it was tedious and painful to depress the accelerator pedal in a partial stroke. Various constant speed traveling devices have been proposed for this purpose, but they have the problem of complicated structures.

This invention was made by focusing on such conventional problems, and it is an accelerator link (a part of RhM; two I11 control shafts are connected, and this control shaft is fixed to the mouth/tsuku m structure and 1 coyol). It is an object of the present invention to solve the above problems by providing a constant speed traveling device for a vehicle that maintains a constant speed with a simple structure.

Hereinafter, this invention will be explained based on the drawings. 1st to 5th
The figure shows an embodiment of the present invention.

First, to explain the configuration, a pebble arm 2 having an accelerator pedal 1 at its lower end is pivotally supported on the vehicle body via a bracket 3 at a bin 4, an accelerator wire 5 is connected to the upper end of this pebble arm 2 via a bin 6, and a spring 32 is attached to the pebble arm 2. This is a conventional accelerator pedal device being biased in the return direction. This pebble arm 2 extends upward, and a control shaft 7 is rotatably connected to the upper end of the pebble arm 2 by a pin 8. This control axis 7
is formed of a round bar, and fine rack teeth 9 are carved on the upper surface of the central part. The end of the control shaft 7 on the side opposite to the pedal is slidably supported on the vehicle body by a sludge receiver 10.

The control shaft 7 of the round bar portion between the rack teeth 9 and the bin 8 is provided with a lock fi*11 for fixing the position of the control shaft 7. This locking mechanism 11 is composed of a pedestal 12 fixed to the vehicle body and a clamping tool held by a pusher 13 connected to a hydraulic cylinder 14, and a gripping part 15 with a semicircular cross section that grips the control shaft 7. 15 is formed on the pedestal 12 and the pusher 13, respectively, and this gripping portion 15 is made of rubber,
A thin anti-slip plate 16 made of soft resin or the like is attached. +7 is an ID part that guides the movement of the pusher 13. The hydraulic cylinder 14 is fixed to the vehicle body and connected to a solenoid valve 18 through a pipe 19, and the solenoid valve 18 is further connected to a hydraulic power source (not shown) through a pipe 20. In addition, if the hydraulic pressure does not operate in the hydraulic cylinder 14, push the pusher 13.
A spring 21 is installed so that the spring 21 returns without pressing the control shaft 7.

An electric motor 23 having a gear 22 meshing with rank teeth 9 of the control shaft 7 is fixed to the vehicle body.

This electric fi 23 is ON only when the electric motor 23 is activated.
An electromagnetic clutch 24 is installed inside to reduce the rotation speed of the gear 22 and increase the shift torque.
(not shown) is installed inside.

On the other hand, as shown in FIG. 4, a lever 27 equipped with a switch 29 is provided on the column 26 portion of the steering handle 25, and a knob 28 equipped with a three-point rotary switch 30 is provided at the tip of the lever 27. It is provided. These switches 29.30 and electric Fli23, solenoid valve 1

is turned ON, and when it is returned to OFF, it is turned OFF. Then, if you turn the knob 28 clockwise in the C direction, the switch 30 will change to 30.
ONL c, the electric motor 23 rotates so that the control shaft 7 moves in the direction in which the vehicle speed increases, and the /P2
If you turn 8 counterclockwise in direction D, switch 30 will turn on to 30d.
L, the electric motor 23 rotates in the opposite direction in the direction where the vehicle speed decreases. The center of rotation of the knob 28 is the OF'F position.

Next, the effect will be explained. When using this device in a constant speed running system for a vehicle that has been Wr&, for example, when the vehicle is running at a constant speed with the accelerator pedal 1 depressed with the foot at 60 klI/h, the lever on the steering handle 25 is pressed. When you pull 27 toward you in direction B, switch 29 turns O.
When the solenoid valve 18 is activated, the hydraulic pressure is transmitted to the hydraulic cylinder 14, and the operating force of the hydraulic cylinder 14 causes the pusher 13 to move to E.
16.
The control 111I7 is clamped and the control shaft 7 is fixed. As a result, even if the accelerator pedal 1 is released, the position is maintained, and the vehicle continues to run at a constant speed of 60 kph.

Next, if you want to increase the vehicle speed a little or when going uphill, turn the /pu 28 of the lever 27 in the C direction as a fine adjustment device.
At the same time as rotates, the electromagnetic clutch 24 is turned on to move the control shaft 7 in the direction A via the gear 22 and the rack teeth 9, and the accelerator pedal 1 moves in the direction of increasing depression, increasing the vehicle speed. When the knob 28 is set to the neutral OFF position, the operation of this @adjustment device is stopped and constant speed running in this state is continued. Note that when moving the control shaft 7, the torque of the electric motor 23 with a built-in reduction gear is greater than the force that fixes the control shaft 7 with the locking device, and the rotational speed is slow.

On the other hand, if you want to slow down the vehicle speed or when going downhill, turn the switch 28 in the opposite direction to the above, and the switch 30 will move to 30.
dl: ON, the electric motor 23 rotates in the opposite direction to the above, and the control shaft 7
is moved in the opposite direction of A and decelerated.

Next, to release this constant speed device, push the lever 27 in the direction opposite to B, the switch 29 will turn OFF, and the solenoid valve 18 will turn OFF.
is closed, the hydraulic pressure disappears, the piston of the hydraulic cylinder 14 is returned by the spring 21, the pusher 13 moves in the direction E, which is the release direction, and the locking device is released. In this case, the electromagnetic clutch 24 is also turned off, so
The accelerator pedal 1 is returned or becomes freely operable with the foot.

For safety reasons, if necessary, if a separate switch is provided in series with the switch 29, which turns off when the brake pedal or clutch pedal is depressed, in order to release the constant speed traveling device, the lever 27 may not be operated. The lock device can be released, which is effective when you want to brake suddenly or decelerate suddenly.

Further, in the embodiment described above, the control shaft 7 is provided on the accelerator pedal arm 2, but it may be provided on a part of the link mechanism between the carburetor and the accelerator pedal.

As explained above, according to the present invention, the configuration is such that a control shaft is connected to a part of the accelerator link mechanism, and the control shaft is fixed by a lock mechanism to maintain a constant speed. Since the present invention is made into a device, it is possible to obtain a constant speed traveling device for a vehicle that is easy to operate and has a simple structure.
