Definitions
- the invention relates to a sealing device for slack adjusters, in particular of rail vehicles, for sealing a pipe against a rod which is displaceably guided in the pipe, the pipe and rod being rotatable relative to one another.
- Such sealing devices have long been known in various embodiments in rail vehicle technology.
- the main problem of such sealing devices can be reduced to sealing a rod that is movably and possibly even rotatably guided in the tube against the tube in such a way that no water flows along the rod into the tube and can adversely affect the remaining brake rod actuator arrangement.
- Seal arrangements are known from DE 962842 and EP 0353796, in which a sleeve engages with a rod via a sealing ring, the seal being moved with the rod. Since the cuff has an inner Has diameter that is larger than the diameter of the housing, the tube can move into the sleeve. The seal is thus displaced on the rod during relative movements between the rod and the tube, which are longer than the relatively short distance between the sealing ring and an opposite “open” sleeve side, and is subject to wear.
- water can also run between the pipe and the rod (or adjusting spindle) when a pipe stop rests against an inner ring of the sleeve and the water drainage is overloaded, particularly when driving downhill and when the wagon is dripping heavily.
- the invention aims to provide a sealing device for slack adjusters, the sealing function of which is reliably retained even in the event of a greater inclination of the vehicle and strong dripping water.
- the invention achieves this aim by the subject matter of claim 1.
- Advantageous refinements of the invention are specified in the subclaims.
- the invention creates a double-sided water drainage system which remains fully functional even when the vehicle (or wagon) is inclined more strongly and dripping water is present.
- the generic sealing device is accordingly supplemented according to the invention by a sleeve which is arranged in the end region of the tube and has a diameter which is larger than the diameter of the tube.
- a drip ring with sealing ring is slidable on the rod in the sleeve guided.
- the sleeve and drip ring are designed in such a way that a double-sided water drainage system is created.
- bores are provided in the two end regions of the sleeve and the tube and the drip ring each have drip edges projecting axially outward.
- the holes in the sleeve, the drip edges of the pipe and drip ring and the integrated sealing ring thus complement each other in an advantageous manner in the drainage of water.
- Another advantageous guarantee of the invention is designed in such a way that the drip ring is only displaced on the rod during readjustment movements.
- the sleeve advantageously has a length such that the rod with the drip ring is axially free according to the elasticity in the brake linkage and is only moved during readjustment movements.
- Fig. 1 shows an embodiment of a sealing device according to the invention for slack adjusters.
- a sealing device 1 seals an adjusting spindle 2 against an outer protective tube 3.
- the sealing arrangement has a sleeve 4, the inner diameter of which is larger than the outer diameter of the protective tube 3.
- the sleeve 4 is attached at one of its ends via a rubber ring 5 and a clamp 6 with a screw-type clamp 7 to the outer tube 4.
- a drip ring 8 (in the sense of a sleeve which lies on an O-ring with a prestress on an O-ring) which is displaceably guided in the sleeve 4 on the adjusting spindle 2 with a sealing ring 9 not during braking, but is only moved in the case of readjustments on the spindle 3.
- the drip ring 8 which is axially displaceable on the adjusting spindle 3, is displaced under the action of the braking force at the moment when the adjusting spindle and rod do not rotate relative to one another.
