The invention relates to a brake pedal with a variable lever ratio, and belongs to the technical field of automobile brake systems. The brake pedal with the variable lever ratio comprises a pedal support, a first-stage pedal arm, a second-stage pedal arm, a T-shaped pin shaft, a guide block and a brittle gasket. According to the brake pedal with the variable lever ratio, when a booster fails, thelever ratio is automatically adjusted according to the design values of the first-stage pedal arm and the second-stage pedal arm, the braking force is increased, the braking distance is shortened, andpotential safety hazards are reduced. And the brake pedal adopts a pure mechanical trigger structure, is simple and reliable in structure, and can be repeatedly used after the brittle gasket is replaced.

    本发明涉及一种可变杠杆比制动踏板,属于汽车制动系统的技术领域。本发明的可变杠杆比制动踏板包括踏板支架、第一级踏板臂、第二级踏板臂、T型销轴、导向块和脆性垫片。本发明的可变杠杆比制动踏板在助力器失效时,根据第一级踏板臂和第二级踏板臂设计值自动调整杠杆比,增加制动力,缩短制动距离,降低安全隐患。而且本发明的制动踏板采用纯机械式触发结构,结构简单、可靠,更换脆性垫片后即可反复使用。
