Abstract

PURPOSE:To perform acceleration and braking through single pedal, by operating a brake lever in the direction to release braking force against a resilient member while interlocking with stepping of accelerator pedal. CONSTITUTION:Upon stepping of an accelerator pedal 30, a brake lever 70 interlocked with the accelerator pedal 30 through a coupling member 76 will rotate against a spring 72 to release braking force of a brake system 26. At the same time a wire 34 coupled to the accelerator pedal 30 is stretched to rotate a regulating board 38 around a pin 40 thus to rotate an arm 46 around a pin 48 and to increase rotation of engine 28. Upon resetting of the accelerator pedal 30 to pre-step position, rotation of engine 28 will drop to move the brake lever 70 in braking direction through the spring 72 thus to enlarge a brake shoe 62 and to perform braking.

Description

[Detailed description of the invention] The present invention relates to a recreational vehicle with an internal combustion engine.

In conventional amusement vehicles equipped with internal combustion engines, acceleration of the vehicle is performed by depressing a slot pedal, and braking of the vehicle is performed by depressing a brake pedal. However, since play vehicles are usually driven by young children, it is preferable to be able to perform acceleration and braking operations with a single pedal, as this makes driving easier.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to propose an internal combustion engine-equipped recreational vehicle that can perform both acceleration and braking operations with a single pedal.

In order to achieve the above object, the present invention provides an accelerator pedal connected to a throttle valve of an engine carburetor, a brake lever provided in a brake device for applying or releasing a brake force, and a brake lever connected to an accelerator pedal connected to a throttle valve of an engine carburetor. It has a neutral member biased in the direction of applying force and a connecting member connecting the accelerator pedal and the brake lever, and when the accelerator pedal is depressed, the brake lever resists the biasing force of the elastic member. It is characterized in that it receives a force in the direction of releasing the braking force of the brake device Pi-.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an internal combustion engine-equipped recreational vehicle according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a side view of a recreational vehicle with an internal combustion engine according to the present invention, and FIG. 2 is a rear view thereof. In the figure, 10 is the body frame, 1"2 is the front cover, 14 is the rear cover, and 16 is the front cover.
is a passenger seat, and 18 is 71 dollars. Further, 20 is a front wheel, 22 is a rear wheel, 24 is a rear wheel axle on which the rear wheel 22 is provided, and 26 is a brake device attached to the rear wheel axle 24. Also, inside the rear cover 14 is an engine 28 for driving the front wheels.
is provided.

An accelerator pedal 30 is pivotally supported on a bracket 32 at the front of the vehicle body frame 10. Accelerator pedal 30 is connected to carburetor 52 of engine 28 via actuation wire 34 shown in FIG.

That is, the actuating wire 34 is held by supports 35 and 36, and its rear end 37 is attached to an adjustment plate 38. The adjustment plate 38 is rotatable via a pin 40, and one end 42 thereof
is an arm 46 connected to the throttle valve via a spring 44.
It is connected to the lower end portion 47 of. Arm 46 is pin 48
It is rotatable around the center and connected to the throttle valve of the carburetor 52. In FIG. 3, 50 is a fuel tank and 54 is an air cleaner.

Next, the structure of the brake device 26 will be explained.

Brake equipment JF: Brake drum 60 that constitutes C26
are attached to the axle 24 and rotate together with the axle 24. On the other hand, inside the brake drum 60 is a pair of brake shoes 62.
．． 62 is pivotally supported on the fixed side member via pins 64 and 64. The brake shoes 62, 62 are biased by a spring 66 in the diameter reduction direction (brake force release direction). Between the tops of the brake shoes 62 and 62 is a cam 68.
is disposed, and when this cam 68 is fully extended i, the brake shoes 62, 62 are expanded against the biasing force of the spring 66, and come into pressure contact with the brake drum 60 to actuate the braking force. Cam 68 is rotated by brake lever 70. One end of a spring 72 is attached to the brake lever 70, and other than the spring 72
1M is attached several times to the vehicle body 011j via a bracket 74. The spring 72 biases the brake lever 70 in the direction in which the brake shoe 62 expands in diameter, that is, in the direction in which braking force is generated. The grooved brake lever 70 is connected to the accelerator pedal 30 via a connecting member 76.

The operation of the embodiment according to the present invention constructed as described above is as follows. First, when the driver does not depress the accelerator pedal 30, the brake lever 70 is biased by the spring 72 in the direction in which braking force is applied, and therefore, in this state, no braking force is applied to the recreational vehicle. φ is in progress.

Next, when the driver depresses the accelerator pedal 30, the brake lever 70, which is connected to the accelerator pedal 30 via the connecting member 76, rotates against the urging force of the spring 72, and the braking force of the brake device 26 is Release. At the same time, the wire 34 connected to the accelerator pedal 30 is pulled, causing the adjustment plate 38 to rotate around the pin 40. Adjustment plate 3
8 rotates, the arm 46 rotates around the pin 48,
The rotational speed of the engine 28 increases and the amusement vehicle begins to move.

Also, when you release your foot from the accelerator pedal 30 and return it to the position before you depressed it, the engine rotational speed decreases and the automatic clutch (centrifugal clutch, etc.)
When the brake lever 70 is released, the spring 7
2, the brake force is moved toward the power direction, and the brake shoes 62 are expanded to apply a braking force to the amusement vehicle. When the foot is completely removed from the accelerator pedal 30, the engine operates in idling mode, and the brake device 26 completely stops the vehicle.

As explained above, in the recreational vehicle with an internal combustion engine according to the present invention, since the throttle operation and the brake operation are performed with one pedal, even children can easily operate the vehicle. .
