Description

[Detailed Description of the Invention] This invention relates to a disc brake for a vehicle such as a motorcycle.

Motorcycles are sometimes equipped with disc brakes on their wheels. In this case, normally, as shown in FIG.
The caliper E is attached to the fork F on the vehicle body side, and the brake pads of the caliper E are used to pinch both sides of the disc plate D to apply the brakes. Disc plate D
The larger the diameter, the greater the braking torque that can be obtained when braking, and the better the performance. However,
If the diameter of the disc plate D is increased, the caliper E will also be located on the outside.
However, since it hits the rim G and tire H, there is a limit to how large it can be. Furthermore, recently, as the diameter of tires tends to become smaller, it is increasingly difficult to increase the diameter of the disk plate D. In order to improve braking performance, disc brakes, called double disc brakes, are installed on both sides of wheel A.
Manufacturing costs will also double.

This idea is an improvement based on these points.
The present invention will be described below with reference to an embodiment shown in FIGS. 2 and 3.

The disc plate 1 is made by stamping a steel plate into an annular and disc shape. The outer periphery of the disk plate 1 is placed along the inside of the rim 3 of the wheel 2 and fastened with screws 4. The caliper 6 attached to the fork 5 on the vehicle body side is inserted and attached from the inner peripheral side of the disk plate 1 so as to sandwich both sides of the disk plate 1.

The effect will be explained.

Since the outer circumferential portion of the disk plate 1 is fastened along the inside of the rim 3, the outer circumference of the disk plate 1 can be made large in diameter close to the rim 3. The caliper 6, which brakes by holding the disc plate 1, is installed from the inner peripheral side of the disc plate 1, so there is no fear that the caliper 6 will hit the rim 3 or the tire. In this way, the disc plate 1 can be made to have a large diameter and have a high braking force that can provide a large brake torque.

As explained above, this invention involves tightening the outer circumference of an annular, disc-shaped disk plate along the inside of the rim of the wheel, and attaching the caliper between the disk plates from the inner circumference of the disk plate. Therefore, the disc plate can be made large in diameter and can provide a large braking force.
And since the caliper is installed from the inner circumferential side of the disc plate, there is no need to worry about it hitting the rim or tire, which is advantageous in terms of space. In this way, high braking force can be obtained without the need for double discs, and the caliper can also be made smaller, making it cheaper to manufacture.
