Abstract

PURPOSE:To improve the braking capacity of the disk brake without the necessity of increasing the weight of the brake and the cost thereof by a method wherein an intermediate pad is provided for a single caliper so that a plurality of disk plates are braked. CONSTITUTION:A pair of pads 10 and 11 comprising support plates 10a, 11a and friction members 10b and 11b and the intermediate pad 12 comprising a support plate 12a and a friction member 12b are slidably supported by a support shaft 13 within a body 8. The three pads 10, 11 and 12 are made to come close to one another by the operation of a piston 14 arranged in the body 8 and the movement of the body 8 itself and so the friction members 10b, 11b and 12b come into pressure contact with a disk plate 6 to thereby brake the latter. In this case, when two or three intermediate pads are used, it is made possible to brake three or four disk plates simultaneously.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a caliper VC of a disc brake device for vehicles such as motorcycles.

A conventional caliper brakes only one disc plate.

When the number of disc plates (m) is increased in order to improve the braking ability of a disc brake device, a corresponding number of calipers are required according to the number of disc plates.

However, since calipers are relatively heavy and only have one high pitch, using multiple calipers will increase the electric charge of the entire disc brake device, increasing the cost.

The present invention has been made in view of these circumstances, and its purpose is to enable braking of several disc brakes (V-) with one caliper.
The purpose of this invention is to improve braking ability without increasing electric shock or increasing costs.

A view of an embodiment in which the present invention is applied to a front wheel disc brake device of a motorcycle, with reference to the drawings, shows that
In Fig. 1, (1) is the front fork, (2) t;
tThe front wheel is supported by the lower end of the front fork (1) via the wheel (3), and (4) is a disc brake device.

Tisfu brake equipment, wheel hub of 3 front wheels (2) (
It consists of a disc plate (6) provided on the left and right sides of the disc plate (5), and a caliper (7) that moves the disc plate (6).

Multiple disc grate <6), for example two discs, can be installed in parallel to the wheel hub (5).・It rotates together with the wheel (5), that is, the front wheel (2).

The body (8) of the caliper (7) is attached to and supported by the actuator tube (la) AC of the front fork (1), and during braking, the body (8) is attached to the outer tube (1a).
) to the axle (3) in the direction of the paddy.

As shown in Figure 2, the body (8) has a pair of opposing pads (If) 1.1υ located on both sides of the recess (9), and two pads (T) #αα with the same curve on both sides. An intermediate pad (6) located between the disc plates (6) of the disc plate (6) is provided.

The pads α0(]υ on both sides are support plates (1(kLX

The intermediate puffer tray 4 has a support plate (12a) and the support AJi (1
The support plate (12a) is slidably supported on the support shaft (IJ), and the support plate (12a) is slidably supported on the support shaft (IJ). Along 03, the intermediate pad @ is capable of approaching and separating IJ from the pad α[) glic on both sides.Three pads configured in this way 0q (b) (o is body 18) VC was provided. Operation of piston (b) and -f:
Due to the movement of the body (8) itself as a result of the movement, the friction materials (1ob) Qxb) approach each other and narrow the I alignment between them.

From the above, one caliper (7) can brake with two gray discs (6), but if you reduce the number of intermediate pads (6) of the same caliper (7) to two or three, , it is also useful to brake three or four disc grate (6).The present invention is based on the above-mentioned motor vehicle, which is equipped with a pair of pads and a disc grate (6) provided between them. The intermediate pad allows machine-drinking disc braking, and as a disc brake device, the braking ability can be improved without increasing the amount of electricity or increasing the cost.
