The invention relates to a decoupling type electric power-assisted braking device. The device comprises a shell and a pedal rod assembly arranged on the shell. The device 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; the pedal rod assembly is provided with a first piston moving along thefirst piston cavity; the first piston divides the first piston cavity into a first cavity and a second cavity; the second cylinder body is provided with a second piston cavity; a second piston is arranged in the second piston cavity; the second piston divides the second piston cavity into a third cavity and a fourth cavity, 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, the second cylinder body is provided with a reset piece for resetting the second piston, and a speed reduction transmission assembly is arranged between the electric booster and a brake pump ejector rod of the brake pump assembly. By the adoption of the scheme, the decoupling type electric power-assisted braking device simulates the stepping feeling of a traditional automobile pedal brake and improves the comfortable pedal feeling in the driving braking process.
本发明涉及一种解耦式电动助力制动装置,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,第二缸体设置有第二活塞腔,第二活塞腔内设置有第二活塞,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,电动助力器与制动泵总成的制动泵顶杆之间设置有减速传动总成。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解耦式电动助力制动装置。
