摘要:
In a brake operating device, a lever ratio changing apparatus interconnects a brake pedal assembly that has a brake pedal lever pivotally connected to a support structure at one end with a brake pedal member connected at an opposite end and a brake booster device. The lever ratio changing apparatus includes a connecting member, a guide member and a pivot pin element. The connecting member is movably connected at a first end to the brake pedal lever between the pivotal connection and the brake pedal member and an opposite second end movably connected to the brake booster device. The guide member is fixedly connected to the support structure. The pivot pin element is connected to the connecting member and is slidably movable within the guide member. As the brake pedal assembly moves from a non-braking position to a braking position, a leverage ratio R/r varies wherein R is defined as a first distance measured between the pivotal connection and the brake pedal member and r is a second distance measured between the pivotal connection and the pivot pin element.
