Braking device for joystick type vehicles

Abstract

Provided is a joystick type vehicle braking device that can achieve miniaturization of a linkage mechanism and ensure good operation of a hydraulic master cylinder for linkage. The mechanical rear wheel brake (3) is actuated by operating the brake pedal (5) that rotates around the fixed shaft (9), and via the interlocking mechanism (6) including the interlocking hydraulic master cylinder (12) The hydraulic front wheel brake (2) is operated in conjunction with it. The linkage mechanism (6) is equipped with: a linkage hydraulic master cylinder (12); a balance rod (13), the middle part of which is rotatably supported on the outer surface of the upper end of the transmission arm (5b), and the upper end is connected to the rear wheel. The connecting part (8) for the operation of the brake (3); the hydraulic input rod (14) is rotatably supported on the outer surface of the lower side of the transmission arm (5b) by using the fixed shaft (9), and the upper side can be connected with the balance rod (13) It is rotatably connected and protrudes downward from the fixed shaft (9), and an operating arm (14a) for operating the interlocking hydraulic master cylinder (12) protrudes from the lower end.

Description

technical field [0001] The present invention relates to a brake device for a joystick-type vehicle such as a motorcycle, and more specifically, to a brake pedal that operates a mechanical brake and interlocks a hydraulic brake through an interlocking mechanism. Braking device for joystick-type vehicles that work on the ground. Background technique [0002] Conventionally, as a joystick-type vehicle brake device that operates a mechanical brake through an operation of the brake pedal and operates a hydraulic brake in conjunction with a linkage mechanism, there is a device that uses a fixed shaft to brake the brake. The middle part of the pedal is rotatably supported on the vehicle body, the pedal arm extends from the fixed shaft to the front of the vehicle body, and the transmission arm extends from the rear of the fixed shaft to the upper side of the vehicle body, and the upper end part of the transmission arm rotatably supports the middle part of the balance bar. A push ro...

Problems solved by technology

[0004] However, in the above-mentioned device of Patent Document 1, since the piston of the master cylinder is connected to the upper end of the balance bar protruding upward from the transmission arm above the vehicle body, the master cylinder is arranged at a position away from the fixed shaft, and it is difficult to store it compactly. Linkage mechanism arranged around the brake pedal

In addition, since the pushrod of the master cylinder is connected to the upper end of the balance bar that is installed on the upper portion of the transmission arm and rotates together with the transmission arm, there is a concern that the swing angle of the pushrod will increase, which may affect the cover and piston of the master cylinder.
