The present invention relates to a multiple brake device for a two-wheeled vehicle. In particular, in a two-wheeled vehicle in which a conventional brake is equipped with a band brake and the front wheel is equipped with a hydraulic brake, the hydraulic brake is applied to the rear wheel in addition to the band brake. A multiple brake for a two-wheeled vehicle mounted.

Conventionally, the rear brakes of two-wheeled vehicles such as bicycles, motorcycles, and cycles have only one kind of band brakes. In other words, the bicycle uses rubber brakes to hold both sides of the rim, or a band (drum) brake is mounted on the rear wheel near the pedal gear, and in the case of a motorcycle, the band brake 10 is mounted on the center of the rear rim. However, in the case of the rubber brake, the rubber is easily broken and worn, so that there is a risk of accidents during operation, and it is difficult to replace frequently, and complete braking or sudden braking is difficult. Also, in the case of the band brake 10, the detail of FIG. As shown in FIG. 2, the brake lining 44 ′ attached to the surface of the round band brake shoe 47 is incorporated in the brake drum 50 so that the cam 48 can be operated by the left and right actuation of the brake pipe 11 ′. The brake lining 44 'is attached by the expansion and contraction action of the return spring 46 connected to the left and right rotation shoes and both side brake shoes 47'. The shoe shoe 47 expands or contracts to both sides while supporting the upper anchor 49 of the upper side of the anchor 49 with the anchor shaft 49a, thereby acting as a brake while adding or releasing the friction force of the lining 44 'to the brake drum 50. In this case, except in the case of a new product, dust may be generated due to the wear of the lining 44 'or the wear of the drum 50, and may be caught inside the drum. It is not easy to brake the brakes if you do not adjust the brakes after a certain period of time.In general, the brakes are always adjusted even when cleaning drums, adjusting chains, replacing bearings, and puncture tires. There was a inconvenience to supplement. In addition, the lining is worn out with the naked eye, so if you need to catch a sudden brake while running worn, the risk will follow.

In addition, there is a considerable risk due to the failure of the brake to return to its original position during rapid braking at high speed due to rupture of the lining 44 ', compression and disconnection of the return spring 46. It is troublesome to repair the brake only by disassembling, and the conventional band brake as described above generates a loud noise between the lining 44 'and the drum 50 to stimulate the occupant's nerves. Due to the wear of the drum, the brake is not reduced to its original position before brake braking, so that the engine of the motorcycle is not overwhelmed and the mental burden of the rider is increased. In the past, the drum brakes were connected with metal rods between the pedals of the brakes, which was a risk of damage.

The present invention supplements and improves the above-described drawbacks of the brakes of the conventional two-wheeled vehicle, and installs a hydraulic brake by attaching a separate disc plate to the rear wheel of the two-wheeled vehicle equipped with the conventional drum (band) brake. As it relates to the multiple brake of a two-wheeled vehicle as described in detail according to the accompanying drawings as follows.
