具有至少一个出口阀的具有新型的多路调节(MUX2.0)的浮动活塞主制动缸单元的制动装置和用于压力调节的方法
摘要：
本发明涉及一种用于机动车的制动装置，所述制动装置具有：主制动缸(HZE)和设置在其中的浮动活塞(SK)，所述浮动活塞将第一压力腔和第二压力腔(DR1，DR2)密封地彼此分离，其中第一压力腔(DR1)与第一制动回路(BKI)液压连接并且第二压力腔(DR2)与第二制动回路(BKII)液压连接；处于大气压下的压力介质储备容器(6)；车轮制动器(RB1至RB4)；可电控制的压力供给装置(DE)，所述压力供给装置用于在车轮制动器(BR1-4)中的压力形成和压力释放；阀组，所述阀组具有用于每个车轮制动器(RB1-4)的常开的入口阀/切换阀(SV1，SV2，SV3，SV4)并且具有至少一个出口阀(AV1-4)，每个车轮制动器(RB1-4)可经由其配设的切换阀(SV1，SV2，SV3，SV4)与主制动缸(HZE)的压力腔(DR1，DR2)液压连接，并且也直接地或经由分离阀(TV1，TV2)与压力供给单元(DE)液压连接或可液压连接，其中每个制动回路(BKI，BKII)与压力供给装置(DE)液压连接或可借助于至少一个可控的阀(TV1，TV2，TV2b)与压力供给装置(DE)液压连接，其特征在于，两个压力腔(DR1，DR2)至少在正常的制动增力器运行中，在至少一个车轮制动器(RB1，RB2，RB3，RB4)中进行压力形成和压力释放时加载有压力，所述压力对应于由压力供给装置(DE)产生的压力，并且在制动情况下，其中在至少一个车轮制动器中的压力变化必须以高的动力，尤其在ABS/ESP运行中进行，同时在至少一个车轮制动器(RB1，RB2，RB3，RB4)中，借助于压力供给装置(DE)的容积控制进行压力变化，并且在至少一个另外的车轮制动器中，尤其同时地，经由至少一个出口阀(AV)进行压力释放。
摘要（英）：

The invention relates to a pressure generating device with a piston-cylinder unit (DE), comprising a double-acting piston (1), which sealingly separates two working chambers (3a, 3b) in the cylinder from each other, the piston (1) having two, in particular differently sized, active surfaces (A1, A2) and each active surface (A1, A2) of the piston (1) delimiting a working chamber (3a, 3b). Each working chamber (3a, 3b) is connected to a hydraulic circuit (K1, K2) via a hydraulic line (H3, H4), at least one hydraulic chamber of a consumer (V1, V1K1, V1K2, V2K, V3K, V4K) being connected to each hydraulic circuit (K1, K2), and a drive (M) driving the piston (1) of the piston-cylinder unit (DE). The invention is characterized in that either - each working chamber (3a, 3b) is connected to a storage reservoir (5) for a hydraulic medium via a hydraulic line (H1, H2), at least one switching valve (PD1, PD2) for selectively opening or blocking the hydraulic line (H1, H2) being arranged in each hydraulic line (H1, H2), or in that - one or both working chambers (3a, 3b) is or are connected to a storage reservoir (5) for a hydraulic medium via a hydraulic line (H1, H2), a switching valve (PD1, PD2) for selectively opening or blocking the hydraulic line (H1, H2) being arranged in the one or in both hydraulic lines (H1, H2) and/or one outlet valve (AVi) for directly releasing pressure from the respective chamber into the storage reservoir (5) being associated with one or more hydraulic chambers of the consumers. The pressure chambers (3a, 3b) and/or the hydraulic lines (H3, H4) are interconnected via a connecting line (H5), a switching valve (ShV) for selectively opening or blocking the connecting line (H5) being arranged in the connecting line (H5).
