The invention relates to the technical field of brake systems, and particularly discloses a pedal force simulation device which is characterized in that a cylinder body, a pipe body and a pedal piston of the pedal force simulation device define a sealing cavity, oil liquid in a liquid storage pot enters the sealing cavity through a first oil inlet and a second oil inlet, the stroke of the pedal piston can be divided into two sections, and the two sections are connected with each other; the pedal piston in the first section overcomes the friction force between the piston and the piston hole and the counter-acting force of oil on the pedal piston; and the second section is that the pedal piston seals the second oil inlet, and oil in the sealing cavity flows to the oil inlet of the pedal simulator from the oil outlet. By controlling the relative position of the pipe body and the cylinder body and controlling the position of the second oil inlet relative to the pedal piston, the length of the first section of stroke is adjusted, and the device solves the problems that if the relation between force and stroke needs to be adjusted, only internal mechanical parts can be detached and replaced, operability is complex, and cost is high. And the same pedal force simulation device cannot realize the real-time adjustment of the stroke and the force.

    本发明涉及制动系统技术领域,具体公开了踏板力模拟装置,该踏板力模拟装置的缸体、管体和踏板活塞围设成一个密封腔,储液壶内的油液通过第一进油口和第二进油口进入到密封腔内,踏板活塞的行程可分为两段,第一段中的踏板活塞克服活塞和活塞孔之间的摩擦力,以及油液对踏板活塞的反作用力;第二段为踏板活塞将第二进油口封闭,密封腔内的油液从出油口流向踏板模拟器的进油口。通过控制管体和缸体的相对位置,控制第二进油口相对踏板活塞的位置,进而调节第一段行程的长度,该装置解决了如果要调整力和行程的关系,只能通过拆卸更换内部机械零部件来实现,可操作性比较复杂,同一个踏板力模拟装置无法实现行程和力的实时调节的问题。
