Definitions
- the invention relates to a chassis of a rail vehicle with radial adjustable wheelsets according to the Oberbergriff of claim 1.
- the proposed chassis is particularly applicable to freight wagon bogies.
- the invention is based on the object, in particular for Freight wagons usable, improved chassis with radial to specify adjustable wheelsets.
- the achievable with the present invention consist in particular that the proposed chassis of a rail vehicle mti radially adjustable Has a relatively low weight wheelsets, a track-saving and quiet Operation is possible and also realtiv producible economically.
- the small one Weight is particularly due to the compact, functionally integrated design reached.
- the quiet operation is caused by the quasi-optimal radial position reached.
- the compact design of the sound reflecting surfaces as well as the vibrating surfaces minimized.
- Fig. 1 is a side view of a portion of the proposed suspension a rail vehicle with radially adjustable wheelsets shown. It is a Impeller 1 to recognize a chassis of a rail vehicle, the axis of the second in a known manner on both sides by means integrated in Achslagergeophusen 3 Axle bearings is stored.
- the rail is designated by numeral 4.
- the upper ends of the coil springs 5 and 6 engage in friction wedges 8 and 9 on or press against these friction wedges whose inclined tops of oblique Levels 10 and 11 of a receptacle 12 of the chassis frame or Bogie frame are supported.
- the directed to the axle box 3 Side surfaces of the friction wedges 8 and 9 are provided with friction plates 13 and 14, respectively.
- Fig. 3 is a section of a wheel of the rail vehicle is shown. It is the impeller 1 with axis 2, axle bearings 15, axle bearing housing 3, 7 receiving the Axle bearing housing and receptacle 12 of the chassis frame or Detect bogie frame.
- the lateral movement possibility between Wheel and frame of the bogie is characterized by a stop 16 of the Chassis frame or bogie frame limited to the axle box.
- Fig. 4 is a plan view of a portion of a wheel of the railway vehicle shown.
- wheel 1 with axis 2
- axle bearing 15 with Axle bearing housing 3
- the two coil springs 5, 6 the receptacle 7 of the Achslagergeophuses and the two friction plates 13, 14 can be seen.
- Fig. 5 is a side view of a bogie 17 with two sets of wheels railway vehicle shown.
- the bogie frame is advantageous as torsionally soft H-frame without head support. conventional In contrast, solutions have a head carrier.
- the bogie 17 has two wheelsets 18, 19, wherein for the storage of the axes not the closed Axle bearing housing according to Figures 1 to 4, but change bearing housing 20, 21 serve.
- each removable bearing housing 20, 21 two separate receptacles 22, 23 for the coil springs on.
- removable lower bearing shells 24 form the lower housing portion of a Replacement bearing housing or axle bearing housing.
- each coil spring has an inner spring and an outer spring which are preferably are provided concentrically with each other.
- Friction damping results from the pressure force, which depends on the spring load and the Friction coefficient between the friction plate 13, 14 and the axle box 3, 20, 21st is.
- the friction damping according to the load of the Rail vehicle proportionally increased to the desired extent.
- the commercial friction pairings friction plate 13, 14 / axle bearing housing 3, 20, 21st are chosen so that no noise in the movements occurring arise.
- the transverse suspension is via the Flexicoil Lucky the coil springs 5, 6. Die Movement in the transverse direction, ie transverse to the direction of travel, takes place between Axle bearing housing 3, 20, 21 and located in the receptacle 12 friction wedges 8, 9. The friction wedges 8, 9 are in turn relative to the chassis frame or Bogie frame of the rail vehicle in the transverse direction. To If the maximum permissible transverse movement is reached, the stop takes place between Bogie frame and axle box 3, 20, 21. The transverse movement is also - as the vertical movement - on the vertical friction plate 13, 14 of the Reibkeils 8, 9 to the axle box 3, 20, 21 damped. Again, takes place in the given and desired dimensions, the friction damping depending on the payload.
- the radial adjustability of the wheelset 18, 19 takes place in two stages.
- the first Stage in which the Tx forces are smaller than the friction force occurring, takes a Turning movement due to the distance between the middle bearing center and friction wedge height.
- the moment generated by the distance about the transverse axis is a Oscillation of the axle bearing housing 3, 20, 21 to the support point of the Reibkeils 8, 9 to the axle bearing housing 3, 20, 21.
- the pendulum motion the takes place above the center of the wheel set 18, 19, a longitudinal movement in the plane of Radsatzsearchmitte causes. This can be small in the first stage Steering movements of the wheelset 18, 19 can be realized.
- the complete construction of the device according to the invention results from the Arrangement of only one coil spring unit next to the axes or Axle bearings per impeller. This advantageously gives a realtiv short lever arm of the spring forces on their upper and lower supports relative the axis 2 and in particular the storage of the bogie frame on Car body.
