Definitions
- the present invention relates to a spring brake cylinder for a brake of a rail vehicle according to the preamble of claim 1.
- Such spring brake cylinders are used in particular in bogies of rail vehicles as part of a parking brake.
- a spring brake cylinder has a spring piston that can be moved axially within the cylinder housing, which can be moved on the one hand by a storage spring to actuate the brake when the pressure drops and on the other hand by a spring pressure chamber that can be pressurized with pressure medium to release the brake.
- a piston rod that actuates the brake caliper can be moved axially with the spring piston.
- Such a spring brake cylinder usually also has a manually operated, mechanical emergency release device, which is used when a brake calliper braked by a spring brake cylinder needs to be released when no compressed air is available as an energy source.
- a manually operated, mechanical emergency release device which is used when a brake calliper braked by a spring brake cylinder needs to be released when no compressed air is available as an energy source.
- Such emergency release devices are controlled, for example, via a Bowden cable.
- Such an emergency release device usually consists essentially of an emergency release actuating device, with which, for example, a Bowden cable is manually operated, and an emergency release mechanism that can be actuated by the emergency release actuating device and is attached to the cylinder housing of the spring brake cylinder.
- the object of the present invention is to further develop a spring brake cylinder so that the assembly and maintenance of the emergency release device can be carried out in a simpler manner.
- the spring brake cylinder has a cylinder housing, a spring-loaded piston which is axially movable within the cylinder housing and which is movable on the one hand by a storage spring for actuating the brake in the event of a drop in pressure and on the other hand by a spring-loaded pressure chamber which can be pressurized with pressure medium for releasing the brake.
- a piston rod can be moved axially with the spring-loaded piston.
- the spring-loaded brake cylinder also has an emergency release device for manually unlocking the brake without pressure medium.
- the emergency release device has an emergency release actuating device and an emergency release mechanism that can be actuated by the latter.
- the emergency release mechanism has an adapter housing in which a coupling part preloaded into a neutral position by a spring element and a force transmission member connected to the emergency release actuating device and the coupling part are accommodated.
- the adapter housing can be attached to a housing cover of the cylinder housing.
- the housing cover of the cylinder housing has a cylindrical receptacle with a locking pawl protruding into it.
- a cylindrical part of the adapter housing can be inserted into the cylindrical receptacle.
- a bayonet attachment is arranged on one end of the coupling part in the adapter housing. The adapter housing can thus be rotated around a rotation axis of the cylindrical part of the adapter housing by engaging behind the locking pawl. can be locked onto the housing cover of the cylinder housing using the bayonet attachment of the coupling part.
- the adapter housing can be inserted into the housing cover from a first side and locked into place by turning it on the housing cover, so that accessibility from the side of the housing cover opposite the first side is not necessary.
- the power transmission element is designed as a Bowden cable.
- a Bowden cable housing enclosing the Bowden cable outside the adapter housing is fastened to the adapter housing by means of a locking plate, wherein the locking plate is detachably fastened to a cover of the adapter housing mounted remotely from the bayonet attachment.
- Such a locking plate also enables easy assembly and maintenance because the emergency release mechanism and the emergency release actuation device can be quickly attached and separated.
- the screws themselves are also preferably secured to the respective component in a way that prevents them from being lost.
- one screw shaft of the screw is preferably provided with an undercut.
- the cover of the adapter housing has at least one further receptacle for securing a further Bowden cable and a Bowden cable housing.
- Fig. 1 is a schematic representation of a generic spring brake cylinder according to the prior art
- Fig. 2 is a plan view of a housing cover of a cylinder housing with an emergency release actuating device attached thereto according to the prior art
- Fig. 3 is a schematic isometric representation of an embodiment variant of a spring brake cylinder according to the invention with cylinder housing, housing cover and attached adapter housing of an emergency release mechanism,
- Fig. 4 an isometric view of the emergency release mechanism with attached bayonet attachment
- Fig. 5 an isometric view of an adapter housing inserted into a recess in the housing cover before rotational fixation
- the adapter housing 150 can be easily fixed to the housing cover 130 by inserting it into the housing cover 130 of the cylinder housing 120 from one side of the housing cover 130 of the cylinder housing 120 and then rotating it on the housing cover 130, without access to a side opposite the receptacle 131 in the housing cover 130 being necessary.
