Title:
スプリングパーキングブレーキを有する商用車両用の電気空圧式のパーキングブレーキモジュール
Document Type and Number:
Japanese Patent JP6905641
Kind Code:
B2
Abstract:
The invention relates to an electropneumatic parking brake module (1), having a reservoir connection (2) for connecting a compressed air reservoir (3), at least one spring mechanism connection (4) for connecting at least one spring-loaded brake cylinder (6), an electropneumatic inlet-outlet valve unit (10), which can assume at least one first switch position and one second switch position, wherein, in the first switch position, the inlet-outlet valve unit (10) of the reservoir connection (2) is connected to the spring mechanism connection (4) in order to modulate a spring mechanism brake pressure (pF), and, in the second switch position, the inlet-outlet valve unit (10) of the spring mechanism connection (4) is connected to a vent (5) of the inlet-outlet valve unit (10). According to the invention, there is a pneumatically controlled bypass unit (12) for maintaining a ventilation state or venting state of spring-loaded brake cylinders (6) connected to the spring mechanism connection (4) while in a currentless state of the electropneumatic inlet-outlet valve unit (10).
