While being located in the center of the device body 20, wear of the wire due to friction with the wall of the device body 20 can be prevented.

Hereinafter, with reference to the accompanying drawings will be described the operation of the mechanical constant speed traveling apparatus according to the present invention.

First, Figure 3 is a partial cutaway cross-sectional view showing when the traveling device is ruled by the locking and unlocking device in the constant speed traveling device according to the present invention, with respect to Figure 1 described above, fully manual, semi-manual using the spring force Or pull the wire W3 by operating the automatic locking / unlocking device 60 using a stepper motor, the wire W1 connected to the right end of the lever 53 of the unlocking tool 50 and the fixture 40 Pulling the wire (W2) connected to the end of the supporting portion (43b) so that the unlocking device 50 and the fastener 40 repulsed against the elastic force of the spring (S1) (S2), both chambers (23) (25) of the device body (20) ) Flows into. Accordingly, the ratchet gear 41 of the fixture 40 is separated from the ratchet 45a so that the constant speed traveling device of the present invention has no effect on the acceleration of the vehicle.

Next, FIG. 4 is a partial cutaway cross-sectional view illustrating a case where the brake pedal is depressed when the traveling device is released in the constant speed traveling device according to the present invention. When the locking device / release device 60 is released, the constant speed traveling device according to the present invention is provided. It is in the state of FIG. 2A. In this state, when the driver slightly presses the brake pedal because a small braking force is required, the pressurizing member 55a installed on the brake pedal rod L1 and the lever 53 of the unlocking port 50 have a predetermined distance. Therefore, as shown by the broken line in Fig. 2A, the ratchet 45a is fixed to the lower portion of the ratchet gear 41, so that the accelerator is kept in operation and there is no influence.

However, as shown in FIG. 4, when the brake pedal BP is squeezed tightly because a large braking force is required, the pressing member 55a fixed to the pedal BP rod is left of the lever 53 of the release port 50. The end is pressed, thereby pulling the connected wire W1 while lifting the right end of the lever 53 around the hinge H1. Accordingly, the other wire W2 is pulled through the connecting member 31, and the fixture 40 connected to the wire W2 enters the chamber 25 while countering the elastic force of the spring S2. Therefore, the ratchet gear and the ratchet of the fixture 40 are released and thus the accelerator pedal AP is returned to its original state, thereby preventing unnecessary consumption of fuel.

Since the above operation is similar to the apparatus having the alternative release port shown in FIG. 2B and the apparatus having the alternative connecting member shown in FIG. 2C, the description thereof will be omitted.

As described above, the mechanical constant speed traveling apparatus according to the present invention is simply configured mechanically and is easy to install, thereby lowering the manufacturing cost, so that a general driver can be inexpensively purchased to create a new demand.

In addition, the present invention has the effect that can drive a car at constant speed with a simple operation and configuration.

Furthermore, when a small braking force is required through the hatcher, the device of the present invention is not released, and when a large braking force is required, the device is released to prevent an accident risk as well as to prevent fuel consumption.

In addition to the above effects, the greatest advantage of the present invention is that the operation reliability is very high, and when selecting a new vehicle to purchase optional, or can be installed in the existing vehicle to improve the performance of the vehicle.
