[Problem that the invention seeks to solve]

However, in order to perform efficient acceleration driving while operating both the accelerator and the gear shift separately, extremely complicated and troublesome operations were required, and advanced operating techniques were required.

An object of the present invention is to enable smooth and efficient acceleration running with simple operations.

[Means for solving problems]

A characteristic configuration of the traveling device of the present invention is that one manual operation is used for both an accelerator operation system of the engine and a speed change operation of the continuously variable transmission, and the speed increasing operation fFK of the continuously variable transmission is performed by The operation and effect of the above-mentioned manual operation are as follows.9.

In other words, it's a single artifact linked to the engine and continuously variable transmission! Just by operating the JK Sakukai, you can achieve the [Hatsuhaku effect].Accordingly, with a simple operation, you can efficiently and smoothly increase the acceleration performance when driving, improving driving performance and providing comfortable acceleration driving. can now be done.

〔Example〕

Next, the embodiments of the present invention will be taxed based on the drawings.

As shown in Figure 2, a front wheel (2) and a rear wheel (3) are provided at the lower front and rear of the vehicle body/frame (1), and a control section (4) is provided above and behind the control section (4). The engine is equipped with an eye, and the driving force of the engine is transmitted via a belt-type continuously variable transmission (E) to a synchro-shuttle mechanism (E) for switching forward and backward movement including neutral, and this synchro-shuttle mechanism (
E) and the rear wheels (3) are connected to each other by a transmission device (7) to form a traveling device.

In addition, the articulated seat (8) is housed above the engine (eyes).

As shown in FIG. 1 and FIG.
)'s speed change operation rod screams, as well as the synchronized shuttle mechanism (
The operation pedal 04, which is interlocked and connected to the forward/reverse switching arm (E), is provided on the lower step α tank of the control section 6 (4).

In other words, the synchro shuttle mechanism (E) is the input shaft 04)
The shift gear that is spline-fitted to the output shaft (119) through the gear transmission (119 or the chain transmission 41 to transmit
[Shiashi, operation pedal a and synchronized shuttle mechanism (
E) When the operation pedal (121 is stepped forward from the forward/reverse neutral position, the shift gear 95) is engaged with the gear milling device Qt9, and the output shaft (1119) is moved in the direction in which the single unit (io4) moves forward. On the other hand, when the driver presses the pedal to the rear, the shift gear (16) connects with the chain transmission 11J device Oη and rotates the end of the output shaft in the direction in which the single unit moves backward. A switching arm (11) for forward and backward movement is connected via a cam maple atgu so as to swing back and forth.

Further, the belt type continuously variable transmission (5) includes an engine (
The output shaft of IiJ is installed, and the bell Il is tensioned by the tension pulley 4 across the pulleys 4 installed on the variable pulley threshold and the input shaft of the synchronized shuttle & structure (E).
It consists of a control pedal (I) and a continuously variable transmission (E1).
The effective diameter of the variable pulley (to) is changed to enable stepless speed change, which is connected via a speed change operation rod.

Furthermore, the engine (accelerator device t (91) is
It is adjusted so that the idling state is suddenly maintained when the operating condition is poor, and the flexible part with the long hole end is the operating pedal.
It is formed in the accelerator operation part (12A) of 4 is pulled and the engine (E) rotational speed is increased, and when the pedal is pressed to the reverse side, the wire WJ is not pulled and the release is released to 1 and hole 4 so as to maintain the idling state. The tip of the wire (c) is inserted suddenly with some play.

In addition, when pressing the operating pedal in the forward direction, the accelerator device (9) is accelerated while the continuously variable transmission is
(Even if you depress E1 until it suddenly changes gears like a shark high speed, if you depress it further from that position, the engine (one-operation hetaru α power, continuously variable transmission ta+, and accelerator) It is linked to device (3).

[Another example]

In place of the operating pedal 9'4, a lever set of operating tools may be used, and these are not required to be manually operated.

In place of the belt type continuously variable transmission (11), a disk type continuously variable transmission or H5T may be used, and these are simply referred to as a continuously variable transmission.

Instead of the synchro shuttle mechanism 6) described in IO, it is also possible to use a gear transmission device that can be changed forward and backward from K.

On the reverse operation side as well, the operating pedal a and the accelerator device are operated so as to raise the engine rotational speed from an idling state based on the pedal operation above the window. [91 may be linked.

Instead of the IQ wire 4, a rod may be used.
