Description

[Detailed Description of the Invention] This invention relates to a parking brake device for a two-wheeled motor vehicle that operates the rear brake by raising the side stand.

In order to park a motorcycle stably on a slope, or to prevent a motorcycle equipped with an automatic transmission from starting when parked in an idling state, the rear brake is connected to the side stand. The mechanism that operates
Various proposals have been made in the past.

However, the disadvantage of these previously proposed mechanisms is that when the side stand is raised, the brake pedal is rotated, and as a result, the spring force of the return spring of the brake pedal is strengthened, increasing the force required to raise the side stand. There is.

This invention aims to eliminate the above-mentioned conventional drawbacks, and embodiments of this invention will be described below with reference to the drawings.

In Figures 1 to 3, 1 is a side stand; 2 is a side stand;
1 and 2 are brake pedals, and both brake pedals 1 and 2 are rotatably attached to brackets 4 and 5 fixed to the vehicle body frame 3 via shaft bodies 6 and 7, respectively.

8 is a rear brake, 9 is a brake arm thereof, 10 is a brake operating member made of a rod or wire whose one end 10a is connected to this rear brake arm 9, and 11 is a link between this brake operating member 10 and the brake pedal 2. the other end 10 of the brake operating member 10
A U-shaped bracket 12 fixed to b, a connecting body 13 supported by this bracket 12, and its retaining pin 14
The connecting body 13 is slidably fitted into a fitting groove 15 formed in the brake pedal 2.

A control cable 16 connects the side stand 1 and the brake operating member 10, and is composed of an inner cable 17 and an outer cable 18. One end 17a of the inner cable 17 is connected to the side stand 1, and the other end 17b is connected to the connector 11. They are each fixed to the connecting body 13.

One end 18a of the outer cable 18 is attached to a bracket 19 fixed to the vehicle body frame 3 near the side stand 1.
The other end 18b is fixed to a bracket 20 fixed to the front side of the fitting groove 15 of the brake pedal 2.

22 is a return spring wound around the shaft body 7 of the brake pedal 2, and 23 is a stopper member of the brake pedal 2.

Next, the operation of the above configuration will be explained.

First, as shown in FIG. 4, when the brake pedal 2 is depressed and rotated in the direction of arrow A, the connector 1 of the connector 11
3 is engaged with the end 24 of the fitting groove 15 of the brake pedal 2 and moves in the direction of the arrow B, thereby pulling the brake operating member 10 in the direction of the arrow B mentioned above, thereby releasing the rear brake 8 (see FIG. 1). is activated.

At this time, since the control cable 16 is flexible, it bends freely following the rotational operation of the brake pedal 2, so that the operation of raising the side stand 1 is not induced.

On the other hand, as shown in FIG.
When the control cable 16 is rotated in the direction of the arrow to stand up, the inner cable 17 of the control cable 16 is pulled in the direction of the arrow E, and the connecting body 13 fixed to the other end 17b of the inner cable 17 is inserted into the fitting groove 15. As a result, the brake operating member 10 is pulled in the direction of the arrow B, and the rear brake 8 (FIG. 1) is operated.

At this time, since the connecting body 13 slides within the fitting groove 15, the connection between the brake operating member 10 and the brake pedal 2 is released, and a rotational operation of the brake pedal 2 in the direction of arrow A is induced. Never.

When the side stand 1 is retracted, the rear brake 8 is released by an operation opposite to the above.

Therefore, the raising operation of the side stand 1 in the direction of the arrow A and the rotation operation of the brake pedal 2 in the direction of the arrow A do not interfere with each other, and both the brake operation member 10
The rear brake 8 is operated via the .

FIG. 6 shows another embodiment of the connecting part, in which the connecting tool 1
Reference numeral 1 denotes a piston body, which is fixed to the other end 10b of the brake operating member 10 and fitted into a cylinder portion 25 formed on the brake pedal 2.

The other end 17b of the inner cable 17 of the control cable 16 is fixed to this connector 11 by brazing.

In each of the above embodiments, the control cable 16 and the brake operating member 10 are indirectly connected by connecting the control cable 16 to the connector 11. However, the control cable 16 may be directly connected to the brake operating member 10. You may.

As mentioned above, according to this invention, since the side stand and the brake operating member are connected via the control cable, the rear brake is reliably activated by raising the side stand, so when driving the motorcycle on a slope. In addition to being able to park the vehicle stably, it also reliably prevents motorcycles equipped with an automatic transmission from starting when parked in an idling state.

In addition, since the coupling device releases the connection between the brake operating member and the brake pedal when the side stand is raised, the operation to raise the side stand and the rotating operation of the brake pedal do not interfere with each other. There is no disadvantage that the spring force of the return spring of the brake pedal is energized and the force required to raise the side stand is increased, and therefore the raising operation is easy.

In addition, since the above-mentioned connector is slidably fitted into a fitting groove provided in the brake pedal, the structure is extremely simple and compact.
