A brake pedal unit includes a housing defining a bore formed therein. An input piston is slidably disposed in the bore. The input piston is connected to a brake pedal such that engagement of the brakepedal causes movement of the input piston within the bore of the housing of the brake pedal unit. The brake pedal unit is defined to be in an at rest position when the brake pedal in not engaged causing movement of the input piston. A primary piston is slidably disposed in the bore for pressurizing a primary chamber. A primary passageway permits fluid communication between the primary chamber andthe reservoir, wherein fluid flow through the primary passageway is blocked when the brake pedal unit is in the rest position. A secondary piston is slidably disposed in the bore for pressurizing a secondary chamber. A secondary passageway permits fluid communication between the secondary chamber and the reservoir, wherein fluid flow through the secondary passageway is blocked when the brake pedal unit is in the rest position.
一种制动踏板单元包括壳体,该壳体限定形成于其中的孔。输入活塞能够滑动地设置在孔中。输入活塞连接至制动踏板,使得制动踏板的接合导致输入活塞在制动踏板单元的壳体的孔内移动。制动踏板单元被限定成当制动踏板未接合导致输入活塞移动时处于闲置位置。主活塞能够滑动地设置在孔中,以对主腔室进行加压。主通路准许主腔室与储器之间实现流体连通,其中当制动踏板单元处于闲置位置时,穿过主通路的流体流被阻塞。次活塞能够滑动地设置在孔中,以对次腔室进行加压。次通路准许次腔室与储器之间实现流体连通,其中当制动踏板单元处于闲置位置时,穿过次通路的流体流被阻塞。
