A brake upper pump with an adjustable force arm comprises a brake pump body, a brake handle and a piston push rod assembly stretching into the brake pump body. The position where a user holds the brake handle is a grip input position, the joint of the brake pump body and the brake handle is a rotating support point position, the joint of the piston push rod assembly and the brake handle is a thrust output position, and the rotating support point position is located between the grip input position and the thrust output position. An input force arm is formed by the distance between the rotating support point position and a force exerting position where a user holds the brake handle by hand, and an output force arm is formed by the distance between the rotating support point position and the thrust output position; a first force arm adjustable mechanism is arranged at the position of the rotating supporting point and can change the rotating center of the brake handle relative to the brake pump body. Adjustment of the brake force arm is achieved according to the requirements of a user, different brake effects are provided for the user before and after adjustment, different piston thrust is output under the condition of the same grip strength, and the requirements are met.

    一种力臂可调的刹车上泵,包括有刹车泵体、刹车手柄、以及伸入在刹车泵体中的活塞推杆组件;用户握持刹车手柄处为握力输入位,刹车泵体与刹车手柄的连接处为转动支点位,活塞推杆组件与刹车手柄的连接处为推力输出位,转动支点位处于握力输入位与推力输出位之间;转动支点位与用户手持刹车手柄的发力处之间的距离形成输入力臂,转动支点位与推力输出位之间的距离形成输出力臂;转动支点位处设置有第一力臂可调机构,第一力臂可调机构能够改动刹车手柄相对刹车泵体的转动中心。本发明根据用户自身需求实现刹车力臂的调节,在调节前后提供给用户不同的刹车效果,在握力相同的情况下输出不同的活塞推力,满足需求。
