The invention relates to a stepping feeling simulator of an electric power-assisted braking device. The stepping feeling simulator comprises a shell and a pedal rod assembly arranged on the shell. Thestepping feeling simulator further comprises a first cylinder body and a second cylinder body which are fixed to the shell. A first piston cavity is formed in the first cylinder body in the treadingdirection. The pedal rod assembly is provided with a first piston moving along the first piston cavity; the first piston divides the first piston cavity into a first cavity and a second cavity; and the second cylinder body is provided with a second piston cavity in the direction parallel to the treading direction. A second piston moving along the second piston cavity is arranged in the second piston cavity, the second piston cavity is divided into a third cavity and a fourth cavity by the second piston, a damping channel is arranged between the second cavity and the third cavity, the second cavity and the third cavity are filled with hydraulic oil, and the second cylinder body is provided with a reset piece for resetting the second piston. By the adoption of the scheme, the pedaling feeling simulator of the electric power-assisted braking device simulates the pedaling feeling of a traditional automobile pedal brake and improves the comfortable pedaling feeling in the driving braking process.

    本发明涉及一种电动助力制动装置的踏感模拟器,包括壳体及设置于壳体的踏杆总成,还包括固定于壳体的第一缸体和第二缸体,第一缸体内沿踩踏方向设置有第一活塞腔,踏杆总成设置有沿第一活塞腔移动的第一活塞,第一活塞将第一活塞腔分隔为第一腔及第二腔,第二缸体沿平行于踩踏方向的方向设置有第二活塞腔,第二活塞腔内设置有沿第二活塞腔移动的第二活塞,第二活塞将第二活塞腔分隔为第三腔和第四腔,第二腔和第三腔之间设置有阻尼通道,第二腔和第三腔内填充有液压油,第二缸体设置有将第二活塞复位的复位件。采用上述方案,本发明提供一种模拟传统汽车脚踏刹车的踏感,提高驾驶制动时具有舒适踏板感的电动助力制动装置的踏感模拟器。
