Embodiment Construction
[0035] first with the help of a Figure 2 to Figure 10 The preferred embodiment of the spring accumulator brake cylinder 2 shown in FIG. 2 is an example to illustrate the invention as it is applied to a brake caliper, for example as a brake force generator for a disc brake of a rail vehicle bogie.
[0036] here, Figure 2 to Figure 4 Shows two different views of a spring-charged brake cylinder 2 with a housing 4 in which a spring-charged piston 6 is arranged axially displaceable, on the outer circumference of which Seals and slide strips 8a to 8c are distributed. Preferably, two energy-storage springs 14 , 16 are arranged here between the spring-storage piston 6 and the axial housing cover 10 , which is fastened to the inner circumference of the housing 4 by means of a collar 12 .
[0037] A pressure chamber 18 is formed between the spring-loaded piston 6 and the housing 4 , which can be supplied with compressed air via an air connection 20 in the circumference of the housin...

The invention relates to a spring-loaded brake cylinder having a housing (4) in which a spring-loaded piston (6) with a piston rod (24) can move axially , the spring energy storage piston is loaded by at least one energy storage spring (14, 16); the spring energy storage brake cylinder also has an emergency release device (26), which includes: an emergency release operating device, an emergency release mechanism and a holding device ( 30), the emergency release mechanism has a gear (38) for interrupting the force flow between the spring energy storage piston (6) and the piston rod (24), and the holding device is designed to hold the emergency release device (26) at different In the holding position, the holding device has a pawl (30) that can be rotated relative to the gear (38) into an engaged and disengaged position, and the emergency release operating device has at least one movable relative to the housing (4) and can be reset by reset The actuating element (42, 44) loaded by the spring device (46) into its original position and the driver (40) which can be actuated together with the actuating element (44), the driver is used to drive the locking pawl (30) , the way is: when operating the operating elements (42, 44), the operating force is transmitted to the driver (40) and is transmitted from the driver to the stop pawl (30), in order to move the stop pawl ( 30) Transition from the engaged position of the counter gear (38) into the disengaged position. The invention stipulates that a spring device (56; 62) is arranged between the operating element (42, 44) and the driver (40) or between the driver (40) and the pawl (30). The device is connected in parallel with the return spring device (46) and is compressed when the stop pawl (30) is driven by the driver (40) to generate elastic force, which pulls the stop pawl (30) to disengage from the gear (48) in the location.
Description
technical field [0001] The invention relates to a spring-loaded brake cylinder having a housing in which a spring-loaded piston with a piston rod can move axially, said spring-loaded piston passing through at least A stored energy spring is loaded; the spring stored energy brake cylinder also has an emergency release device comprising: an emergency release operating device, an emergency release mechanism and a retaining device, the emergency release mechanism having a piston for interrupting the spring stored energy A gear with a flow of force between the piston rod, the holding device is designed for holding the emergency release device in different holding positions, wherein the holding device has a gear that can be rotated relative to the gear into an engaged and disengaged position The locking pawl, the emergency release actuating device has at least one actuating element that is movable relative to the housing and is loaded into its original position by a return spring de...
