Definitions
- the present invention relates to a vehicle for a rail vehicle, in particular for a metro vehicle, with at least two pairs of wheels arranged opposite one another transversely to the direction of travel. which are rigidly connected to each other by means of an axle, each wheel being resiliently mounted in a rocker which can be pivoted about an essentially horizontal transverse axis. Furthermore, the present invention relates to a rail vehicle consisting of at least two car sets, preferably connected to one another by means of a spherical joint forming car with at least one such chassis
- each wheel is pivotably mounted on a frame of the running gear via a swing arm about a horizontal transverse axis
- the chassis is made by two springs, which are arranged at different distances from the swivel axis and are supported at one end on the rocker arm and at the other end against the chassis frame.
- the spring constants of these springs are chosen so that the swing axis of the rockers is moment-free.
- Another object of the present invention is a rail vehicle, in particular a metro Rail vehicle, in which a chassis with the above properties such it is provided that as much passenger space as possible is made available and that the passage which is as wide and correspondingly short as possible can be created between the individual cars with a simple construction
- the egg of the above-mentioned tasks is achieved according to the invention in that the wings of two wheels of a pair arranged one behind the other in the direction of travel are mounted on a common transverse axis in a chassis frame and the driving frame is positively controlled by means of a symmetrical control.
- This arrangement makes a space-saving and simple solution found, which is also characterized by particularly good running properties and can be implemented mechanically with a comparatively small number of parts.
- the small center distance means that there is no need for an active or passive radial position of the wheels, so that the wear resulting from the radial position can be largely avoided
- a small wheel base is disadvantageous for the smooth running of a bogie.
- this small wheel base can be caused by force gscontrol of the chassis by means of a symmetrical control with particularly good running properties in connection with self-centering of the wheel sets can be successfully used.
- a spring-damping unit of the primary spring stage can be provided radially outside the same in this rocker bearing in the plane of the wheel, so that space for others besides the wheel necessary aggregates or components or for use as cargo or passenger space remains free.
- the floor can be lowered particularly far between the wings of the opposite vehicle sides.
- the rockers are braced against one another by means of at least one spring-damping stage, and the spring-damping stage is set up to absorb forces in the longitudinal direction of the vehicle.
- the primary suspension can be implemented mechanically by a few parts, since only one spring damping stage is required for both rockers.
- the space between the rockers is used efficiently for the primary suspension, so that driving areas that are usually reserved for the primary suspension are used for other purposes, eg a drive can be used.
- a simple and stable construction of the undercarriage results in an advantageous manner if the transverse axis of the rockers is arranged above the axes of rotation of the wheels
- each rocker is designed essentially in the form of a two-armed angle piece, the transverse axis being provided in the angular region, the wheel axis at the free end of a first arm and the free end at the free end of the second arm, the at least one spring-damping unit for influencing the mutual pivotability of the rockers is supported, whereby two rockers on one side of the chassis are supported on the frame via a hinge joint formed by the angular ranges of the rockers and one axle bolt each.
- This construction results in a low profile Space required for the chassis and allows the usable car volume to be extended to just above the wheels.
- the spring-damping unit of the primary suspension can be kept relatively small and compact
- the undercarriage is also designed as a drive undercarriage according to one of the preceding paragraphs, and at least one wheel, preferably each wheel, is connected in terms of drive to a motor-transmission unit, the motor-transmission unit on the
- the outside of the assigned wheel facing away from the undercarriage frame is thus also possible for the undercarriage of the undercarriage construction which realizes the advantages already mentioned, the space-saving arrangement of the motor-transmission units on the outside of the wheel making the space between the wheels as a passenger compartment or for other purposes, z.ß can be used for disc brakes Furthermore, with this arrangement it is possible to service the drives without dismantling the undercarriage.
- the motor-gear unit is resiliently supported or suspended on the frame and connected to the wheel axle by means of a radially movable coupling.
- This construction results in an advantageous reduction in the unsprung mass even in the case of driving gear.
- each motor-gearbox unit is arranged continuously in the range of the wheel circumference for small output sizes or for larger outputs inclined upwards and in the direction of the swivel axis, since this means a particularly space-saving arrangement of the drives and therefore an increase in the passenger compartment in the area of these drives is possible
- a construction that reliably and accurately guides the forces acting on the undercarriage and the wheels gives the features that the undercarriage frame is formed from two plates, at least in sections over the undercarriage length and width, which are arranged at a distance above one another and connected to one another by vertical webs
- a particularly usable space for the construction providing the transport or passenger area can be achieved if the entire undercarriage frame is below the level of the transverse axis, preferably below the level of the wheel axles Stable running of the wheels with a short wheelbase, especially when driving straight ahead and cornering, is made possible according to the invention by the compulsory symmetrical control of the chassis frame, which is achieved in the context of the present invention by a special design of the chassis, in which in the area of the transverse axis on the Chassis frame is articulated at a distance from the longitudinal center plane on each side of the chassis with a longitudinal link, the ends of these two links facing away from the longitudinal center of the chassis being articulated with a transverse element that can be connected to
- a rail vehicle according to the invention consisting of at least two carriages, which are preferably connected by means of a spherical joint and form a train set, is characterized with the effects and advantages already indicated in that at least one undercarriage is provided in the connection area between two carriages
- one carriage body of the adjoining carriages is supported at each end of the suspension via a secondary suspension.
- the undercarriage frame acts as one kind of balance beam, which is supported by the transverse axes and the primary suspension
- a running gear with the symmetrical control already described above is provided and a car body is articulatedly connected to the cross element to which the longitudinally extending links are articulated, and the subsequent car body becomes on the opposite.
- the longitudinal extension is preferably connected to the adjacent car body via an intermediate lever which is aligned transversely to the direction of travel and can be pivoted in a horizontal plane, or via a sliding guide oriented in the longitudinal direction of the vehicle, which enables simple longitudinal compensation for the symmetrical control
