Abstract

DC60 (Problem to be solved) This invention provides a braking device with transmission losses that are reduced in the transmission line for the force. Working from the brake lever is linked to the front wheel brake driving mechanism. Brake device 10 consists of a front wheel brake lever 20 that is arranged on one of the handlebars 4, brake lever 40 is provided. On one side of the handlebar 4 and was connected to the rear wheel brake 17, the front wheel brake driving mechanism 30 was installed on the other side of the handlebar 4 attached to the brake lever 40 linked together to create pressure of The hydraulic fluid 12 is connected to the front wheel brake 14 by the force of Front wheel brake lever 20 or brake lever 40 are linked to create front wheel brake action 14, and a transmission line 21 is provided that extends from one of the handlebars 4 to the other to transmit lever action force. Force the front wheel brake 20 to the front wheel brake driving mechanism 30.

Claims (2)

Claims (all) that will not appear on the advertisement page: 1. Brake device (10) consisting of Front wheel brake lever (20) adjusted to be positioned on one side of the vehicle's handlebar (4) (1); The coherent brake lever (40) is positioned on the second side of the handlebar (4) and is connected to the rear wheel brake (17); Front wheel brake drive mechanism (30) for creating fluid pressure in a hydraulic way (12) connected to the front wheel brake (14) by the working force of the front wheel brake lever (20) or brake levers are linked (40) to establish the front wheel brake function (14); and force transmission parts (21) extending between the first and second side of the handlebar (4) where Front wheel brake drive mechanism (30) It consists of a master cylinder (32) and an arm (31) that receives the load. The front wheel brake levers (20) or the brake levers are linked (40) to the arms (31) that bear the working load of Hydraulic (12), and This arm (31) is shaped so that it can move relative to the working force transmission part (21) when the working force is brought in from the braking lever (40) to the arm (31), there is The special characteristics are The front wheel brake drive mechanism (30) is positioned close to the brake lever. (40) To be able to be positioned on the second side of the handlebar. (4) can and power transmission part Work (21) is adjusted to transmit the working force of the front wheel brake lever. (20) to the front wheel brake drive mechanism (30) 2. brake device (10) according to the claim that 1, where the travel is provided between the coherent brake lever (40) and the front wheel brake drive mechanism (30) in order to delay the transmission of working force from the lever. Brakes coherent (40) to the front wheel brake drive mechanism (30) 3. brake device (10) according to the claim that 2, where the displacement is provided by 4. Brake device (10) according to one of the preceding claims, accompanying Rear wheel brake cable (11) for transmitting the working force of the coherent brake levers (40) to the rear wheel brakes (17); and The input parts (42) that support the working force of the brake lever are linked. (40) to pull the rear wheel brake cable (11) and to transmit the working force to the front wheel brake drive mechanism (30), where the transmission parts (42) This will be attached to the brake lever linked together (40) 5. Brake device. (10) in accordance with claim 4, where parts are imported (42) shall be provided so that it can be moved by the reactive force received by the mechanism. Drive front wheel brake (30) When the brake levers are linked (40) was worked, and The rear wheel brake cable (11) stops the movement of the input part (42) against the reaction force applied by Send parts (42) Therefore, the parts sent in (42) will send the working force of the brake lever connected (40) to the front wheel brake drive mechanism (30) resist the reaction force in the state in which the movement of the input part (42) is stopped 6. Brake device (10) according to claim 4 or 5, where the part Send in (42) there will be a supported section (42b) to be supported by the rear wheel brake cable (11) and The work force sending part (42c) for linking brake levers (40) to the front wheel brake drive mechanism (30) input parts (42) are attached to the brake levers (40) so that they can be rotated motion. And the receptacle (42b) may be deformed to stop moving. It is supported by the rear wheel brake cable (11), and the distance (L1) from the center of motion of the input part. (42c) to the load section Work (42c) is shorter than the distance (L2) from the center to the support (42b) 7. Brake device (10B) according to claim 4, where the input part consists of a equal adjuster (64), and a Equalization (64) will have a rotating section (64a) that will be supported for rotation by lever. Force brakes coherent (40B), the part where the cable is attached (64b) is positioned away from the supported part. Turning (64a) to pull the rear wheel brake cable (11) and working force (64c) provided at Position away from the part being supported for rotation (64a) to direct the working force of the brake lever (40B) to the front wheel brake drive mechanism (32B) 8. Brake device (10) according to claim 7, where the part is supported to rotate (64a) of the input parts will Is provided between the working load (64c) and the line attached (64b) 9. Brake device (10), one of the following, in accordance with claims 1 to 3.
