Definitions
- the invention relates to a device for resilient absorption of impact forces, in particular sleeve buffers for rail vehicles, which consists of two tubular and telescopically displaceable housing parts braced against each other against the force of a spring, one end of which is designed as a pressure plate supporting the spring, the length of the device free of impact force is fixed by a form-locking anti-rotation device fixedly arranged on one housing part and projecting into a recess in the other housing part, the length of the recess corresponding to at least the maximum displaceability of the two housing parts relative to one another.
- Sleeve buffers in rail vehicles are used to dampen shocks in the longitudinal direction of the vehicle.
- the damping is produced by an elastic pressure system which is arranged in the generally two-part buffer housing and is supported against the bottoms of the tubular and telescopically displaceable housing parts.
- the housing parts are braced against each other and against the force of the printing system.
- the blocks of the housing parts are designed as a pressure plate, the pressure plate of one housing part being firmly connected to the rail vehicle and the pressure plate of the other housing part being designed as a buffer plate.
- a sleeve buffer of the generic type it is known to fix the two housing parts braced against one another by an inserted friction spring by means of a two-part retaining ring which lies in a groove at the open end of the inner housing part and forms a stop for the outer housing part, and thus the installation length and also to determine the preload force of such a sleeve buffer.
- the pressure plate of one housing part either the buffer plate or the pressure plate of the other housing part, is fastened to the corresponding housing part with screws.
- a further known sleeve buffer in which the sleeve and the buffer plate are made from one piece, two semicircular shells of U-shaped cross section serve as holders in the sense described above, one flange of which engages in a groove at the open end of the buffer sleeve and the other flange of which Bypasses the buffer sleeve and rests on a shoulder on the buffer tappet, radially with play to it.
- the two half-shells are braced against each other with two screws, which are arranged in approaches and the mutually facing ends of the half-shells. Also in this known buffer there is no tightness to be required for an optimal spring function due to the radial play described.
- the positive locking rotation is usually formed by a feather key, which in a longitudinal groove of the jacket of the outer housing part is inserted and welded to it and which projects into a longitudinal groove of the jacket of the inner housing part and is longitudinally displaceable in this groove.
- DD-PS 209 780 discloses another sleeve buffer of the generic type, in which the two housing parts of the sleeve buffer are clamped together by means of wedges. These wedges are detachably arranged in the longitudinal slots of the jacket of the outer housing part and protrude into longitudinal slots of the jacket of the inner housing part. The longitudinal slots in the jacket of the inner housing part are designed so that the maximum displaceability of the two housing parts relative to one another is not impaired.
- This sleeve buffer described above thus uses a component for bracing the two housing parts with one another and for preventing the two housing parts from rotating relative to one another.
- a disadvantage of this embodiment is, firstly, the type of fastening of the wedges to the jacket of the outer housing part, which requires cams cast or welded onto the jacket of the outer housing part.
- Another disadvantage is that the longitudinal slot in both the jacket of the outer housing part and the longitudinal slot in the jacket of the inner housing part are open to the sliding surface of the two housing parts and to the inside of the sleeve buffer and thus disadvantageously do not offer any protection against the ingress of moisture and dirt .
- Another disadvantage is the design of the wedge, which requires a complex production method.
- the object of the present invention was to design a device of the generic type so that an economical and simple bracing of the two housing parts of the device with one another and a positive locking rotation of the two housing parts against each other is achieved by using a few and simple standard components and that the sliding surface of the two housing parts of the device and the spring of the device against the one are protected from dirt and moisture.
- this object is achieved in that a longitudinal groove which is limited in length and does not penetrate the jacket is arranged on the outside in the jacket of the inner housing part, that at least one opening is arranged in the jacket of the outer housing part in the region of the longitudinal groove of the inner housing part, and in that in the longitudinal groove a positive locking device is inserted through the opening to the outer housing part.
- the longitudinally displaceable kit of the housing parts in the relaxation direction is adjustable by moving the positive locking device in the longitudinal groove before the positive locking device is fastened to the outer housing part.
- the invention advantageously combines the positive locking rotation of the two housing parts of the device with the device for bracing the two housing parts together to form a unit that is simple and economical. Another advantage is that open breakthroughs are avoided both in the jacket of the outer housing part and in the jacket of the inner housing part. The penetration of moisture and dirt is prevented. Another advantage is that the total length of the device can be adjusted precisely against the spring force.
- the device according to the invention consists essentially of the inner housing part 1 that consists of a tubular jacket 1 a and a pressure plate 1 b closing the jacket on one side, and the outer housing part 2, consisting of a tubular jacket 2 a and one closing this one side Pressure plate 2 b, as well as a not shown, in the interior the device located spring.
- the shells 1 a and 2 a of the inner and outer housing parts 1 and 2 are telescopically displaceable.
- at least one opening 5 is provided in the casing 2 a of the outer housing part 2.
- a positive locking device designed as a key 6 is inserted, and welded to the outer housing part 2 within the opening 5 of the casing 2 a.
- the length of the longitudinal groove 3 in the inner housing part 1 between key 6 and the pressure plate 1 b of the inner housing part 1 corresponds at least to the maximum stroke of the device.
- the spring When assembling the device, the spring is inserted into the inner housing part. Then the outer housing part 2 is pushed onto the inner housing part 1 and the feather key 6 is inserted into the longitudinal groove 3. The two housing parts 1 and 2 are then pushed against each other against the force of the spring as far as is necessary to achieve the required overall length of the device. The feather key 6 is then shifted in the longitudinal groove 3 in the direction of the open end of the inner housing part 1 up to the front end of the longitudinal groove 3. The feather key 6 is then welded to the casing 2 a within the opening 5 of the outer housing part. The feather key 6 now acts both as a positive locking rotation of the two housing parts 1 and 2, and as a bracing element of the two housing parts with each other.
