The invention relates to a pneumatic brake cylinder (4) for a vehicle brake, comprising: a brake cylinder housing (24); a brake piston (9) which is axially guided in the brake cylinder housing and has an extendable and retractable piston rod (6) which protrudes through an opening (27) in a bottom (25) of the brake cylinder housing (24); a brake chamber (10) which can be supplied with air and deflated, the brake piston (9) together with the piston rod (6) being in a brake application position when the brake chamber (10) is supplied with air and in a brake release position together with the piston rod when the brake chamber (10) is deflated, and wherein the brake piston (9) delimits the brake chamber (10); a return spring chamber (20) in which a return spring (21), which acts on the brake piston (9) in the brake release position, is accommodated and which is delimited on the one hand by the brake piston (9) and on the other hand by the bottom (25) of the brake cylinder housing (24); a fastening device (2) which is provided and designed to detachably fasten the brake cylinder (4) to a support structure (3) for the brake cylinder (4), the fastening device (2) comprising at least one fastening bolt (11a, 11b; 35a, 35b), which are connected to each other; a ventilation device (29) which cooperates with the return spring chamber (20) such that air can flow out of or into the return spring chamber (20) when a movement of the brake piston (9) by the ventilation device causes a change in the volume of the return spring chamber (20). According to the invention, it is provided that the ventilation device (29) comprises at least one fastening bolt (11a, 11b; 35a, 35b) which, on the one hand, leads into the return spring chamber (20) with a first mouth (30) and, on the other hand, leads into an outer region (32) of the brake cylinder (4) with a second mouth (31).

    本发明公开了一种用于车辆制动器的气动制动缸(4),具有:制动缸壳体(24);具有可延伸和可回缩的活塞杆(6)的在制动缸壳体中被轴向引导的制动活塞(9),活塞杆穿过制动缸壳体(24)的底部(25)中的开口(27)伸出;制动室(10),能被供气和排气,在制动室(10)被供气时,制动活塞(9)与活塞杆(6)一起处于制动施加位置,当制动室(10)被排气时,制动活塞与活塞杆一起处于制动释放位置,并且其中制动活塞(9)界定制动室(10);复位弹簧室(20),复位弹簧室中容纳有将制动活塞(9)加载到制动释放位置的复位弹簧(21),并且该复位弹簧室一方面由制动活塞(9)界定,另一方面由制动缸壳体(24)的底部(25)界定;紧固装置(2),所述紧固装置设置和设计用于将制动缸(4)可拆卸地紧固到用于制动缸(4)的支撑结构(3),紧固装置(2)包括在底部(25)区域中远离制动缸壳体(24)伸出的至少一个紧固螺栓(11a,11b;35a,35b);通气装置(29),其与复位弹簧室(20)配合,使得在通过通气装置使制动活塞(9)运动导致复位弹簧室(20)的体积改变的情况下,空气能从复位弹簧室(20)流出或进入复位弹簧室(20)。根据本发明,规定通气装置(29)包括具有至少一个内部通道(28)的至少一个所述紧固螺栓(11a,11b;35a,35b),该内部通道一方面以第一嘴部(30)通向复位弹簧室(20)中,另一方面以第二嘴部(31)通向制动缸(4)的外部区域(32)中。
