The invention relates to a brake pedal simulator, a brake assembly and a vehicle, the brake pedal simulator comprises a main body part, the main body part is provided with a piston cavity, a piston capable of moving axially is arranged in the piston cavity, and a first spring is arranged in an inner cavity of the piston; the cover body is buckled on the main body part and is used for sealing the piston cavity, a movable separator is arranged in the cover body, the separator is positioned above the first spring and is opposite to the opening of the inner cavity of the piston, a second spring is arranged between the piston and the separator, and a third spring is arranged between the cover body and the separator. The invention provides a three-stage spring arrangement mode, the weight of the pedal force value provided by the first spring can be reduced, foot sensing force value feedback can be better provided, and force value changes in high-temperature and low-temperature environments are obviously improved. Two of the three springs directly act on the piston, the rigidity of the spring in the piston can be increased, the rigidity difference between the spring and the third spring outside the piston can be reduced, force value change is smoother, the overall size is reduced, and the structure is more compact.
本公开涉及一种制动踏板模拟器、制动总成和车辆,制动踏板模拟器包括:主体部,主体部设有活塞腔,活塞腔内设有可轴向运动的活塞,活塞的内腔中设有第一弹簧;盖体,扣设在主体部上用于封闭活塞腔,盖体内设有可活动的分隔件,其中,分隔件位于第一弹簧的上方并与活塞的内腔开口相对设置,活塞和分隔件之间设有第二弹簧,盖体和分隔件之间设有第三弹簧。本公开提供一种三级弹簧布置方式,可以降低第一弹簧提供踏板力值的权重,更好地提供脚感力值反馈,对高温、低温环境下力值变化有明显改善。三个弹簧中其中两个直接作用于活塞,活塞内部弹簧的刚度可以增大,减小与活塞外第三弹簧的刚度差异,使力值变化更加平滑,减小整体体积,结构更加紧凑。
