Title:
BRAKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/055842
Kind Code:
A1
Abstract:
A push rod (63) and a counterforce spring (66) are arranged between a brake pedal (12) and a master cylinder (11), and a void (α), wherein the master cylinder (12) is not activated even when the brake pedal (12) is operated, is set for the push rod (63); thus, until the stroke of the brake pedal (12) eliminates the void (α), the pedal force applied to the brake pedal (12) is transmitted to the master cylinder (11) while elastically deforming the counterforce spring (66), and after the void (α) is eliminated the pedal force applied to the brake pedal (12) is transmitted directly to the master cylinder (11) via the push rod (63). Accordingly, when the brake pedal (12) is operated, the pedal counterforce which is generated initially can be generated by the counterforce spring (66) instead of the master cylinder (11), and the pedal counterforce of the brake pedal (12) can be adjusted freely by setting the spring constant and the set load of the counterforce spring (66), enabling an improvement in the feeling of the pedal.
