Definitions

  • the invention relates to bogies for rail vehicles with at least two wheel sets mounted in axle bearings and at least one cross member.
  • Such bogies are for example from the U.S. 3,948,188 A1 known.
  • bogies in fiber composite construction are known from the prior art, in which the primary suspension is implemented by the bogie frame or by leaf springs in fiber composite construction.
  • a bogie in which the bogie frame is constructed from a resiliently elastic fiber-reinforced material and takes over the task of primary suspension.
  • the DE 36 12 797 A1 discloses a bogie in which the primary suspension is applied by longitudinal members of a double-H-shaped bogie frame, which are made in fiber composite construction.
  • the bogie also has a torsion-elastic plate that connects the side members to one another.
  • the torsionally elastic plate and in particular the side members have a complicated fiber composite structure, since z. B. must change the elasticity behavior of the side members in the longitudinal direction perpendicular to the bogie plane in a defined manner in order to meet the spring properties.
  • Torsion bar suspensions are known from the motor vehicle sector as well as from the tracked vehicle sector, e.g. B. from the DE 920 291 and the U.S. 4,194,761 .
  • torsion bars are called Stabilizers are used in running gears and are usually designed as multi-bent rods that connect the wheel suspensions of the wheels of an axle and the running gear structure to one another. Stabilizers are used to reduce the roll angle of a car body.
  • the invention specified in claim 1 is based on the object of creating an alternative design variant for a bogie of a rail vehicle in such a way that it can be implemented in a lightweight design and manufactured at low cost.
  • the bogies as components of rail vehicles with at least two wheel sets mounted in axle bearings and at least one cross member are characterized in particular by the fact that they can be made in a lightweight construction and can be manufactured at low cost.
  • the axle bearings of a wheel set are articulated to the cross member via two axle levers, so that the axle levers with the axle bearings and the cross member form an H shape.
  • the cross member has at least two torsion bars which are arranged parallel to the axes of the wheel sets and which are firmly connected to the cross member. Furthermore, the torsion bars have spring levers, so that the end area of the spring lever that is not connected to the torsion bar acts on the axle bearing.
  • the bogie of a rail vehicle has at least two sets of wheels, each set of wheels comprising two wheels connected to an axle.
  • the wheel set is stored in axle bearings, which are still articulated to the cross member via the axle levers.
  • two spring levers connected to the torsion bar act on the axle bearings of the wheelset, so that the primary suspension is advantageously at least partially taken over by the torsion bars acting on the axle bearings.
  • the primary suspension is based on a rotary spring movement instead of a known translational spring movement.
  • the geometry and the material of the torsion bars can be adapted to the expected loads.
  • axle bearings are located in the axle levers articulated to the cross member, the cross member and thus the car body connected to it are resiliently arranged.
  • the articulated axle levers can thus also make a contribution to the secondary suspension of the rail vehicle.
  • the proposed bogie comprises individual structures that are geometrically less complex, at least some of which can also be implemented cost-effectively in a lightweight construction.
  • two torsion bars are arranged one after the other on the cross member in the axial direction.
  • the ends of the torsion bars facing each other are connected to the cross member by their end regions.
  • the other ends of the torsion bars had a spring lever.
  • the cross member has an H shape.
  • the end regions of a torsion bar loosely penetrate the opposing legs of the H-shaped cross member.
  • the legs of the cross member can be designed as guides or radial bearings for the torsion bar.
  • the middle area of the torsion bar is firmly connected to the H-shaped cross member.
  • an axle lever is connected in an articulated manner to one end of the leg of the cross member, so that the axle lever joint is a component of the cross member. The axle levers thus extend the legs of the H-shaped cross member.
  • one end region of a torsion bar is located as a movable part on or in at least one radial bearing connected to the cross member.
  • the end area of the torsion bar penetrates the radial bearing and the end of the torsion bar has the spring lever after the radial bearing.
  • the radial bearings for a torsion bar or two torsion bars arranged one after the other can thus be located between the axle levers or in the area of the axle levers.
  • the spring levers can thus be arranged above the axle levers opposite the rails carrying and guiding the wheel sets.
  • the end areas of the spring levers can act on the end areas of the axle levers with the axle bearings.
  • the torsion bar has the shape of a conic section and / or a polygon in cross section.
  • the torsion bar can thus also have profiles over its length. This enables optimal connection and load transfer of the spring lever to the cross member. Profiling over the free length of the torsion bars can also be used to optimize the mechanical properties in dynamic operation.
  • the torsion bars and / or the spring levers are made from a metal or a fiber composite material or in a mixed construction. Due to the low weight, the fiber composite design is particularly advantageous. In particular, glass fibers or carbon fibers or aramid fibers can be used.
  • At least one damping body is advantageously located between the end regions of the axle lever and the spring lever.
  • the damping bodies of the bogie are further spring elements of the primary suspension and the secondary suspension.
  • the damping body consists of an elastomer. This can in particular be a rubber.
  • the cross member is a base body with the links for the swivel joints of the axle levers and with fastening elements for add-on parts.
  • the base body consists of a metal and / or a fiber composite material.
  • Add-on parts can in particular be braking devices and / or drives.
  • the cross member is a beam or a frame.
  • the bogie has further spring elements for secondary suspension and a rotating pan.
  • the other spring elements take on the task of the secondary suspension of the car body.
  • air springs can be provided for this purpose, which are arranged on the cross member.
  • a bogie of a rail vehicle consists essentially of two wheel sets 3 mounted in axle bearings 4, a cross member 1, axle lever 2, torsion bars 5, spring levers 6 and a pivot socket.
  • Fig. 1 shows a bogie of a rail vehicle with external spring levers 6 in a basic perspective view.
  • the bogie has two wheel sets 3, each with two wheels 7 on a common axle 8.
  • the axle 8 is articulated to the cross member 1 via the axle bearings 4, two axle levers 2 and two axle lever joints 9 designed as swivel joints.
  • the cross member 1 is a frame that forms an H-shape with the axle lever joints 9 and the axle levers 2 with the axle bearings 4.
  • Fig. 2 shows the bogie Fig. 1 in a principle top view.
  • the cross member 1 has the at least two torsion bars 5 arranged parallel to the axes 8 of the wheel sets 3.
  • the respective central area of the torsion bars 5 is connected to the cross member 1.
  • the end of the torsion bar 5 has the spring lever 6, the end of the spring lever 6 acting on the axle bearing 4.
  • the torsion bars 5 and the spring levers 6 are thus the primary suspension or part of the primary suspension of the bogie.
  • Fig. 3 shows the bogie Fig. 1 in a basic side view.
  • the end area of the torsion bar 5 penetrates the leg of the H-shaped cross member 1. For this purpose, it has an opening 10.
  • the torsion bar 5 can be supported in the cross member 1.
  • the axle lever joints 9 are components of the H-shaped cross member 1, the axle levers 2 extending the legs of the H-shaped cross member 1.
  • the torsion bar 5 is circular and / or polygonal in cross section. This can have profiles along its length.
  • the torsion bars 5 and the spring levers 6 can advantageously consist of a fiber composite material.
  • the central region of the torsion bar 5 can be located in a non-rotatable manner in a bushing as part of the cross member 1.
  • at least this central area and the opening of the socket are polygonal in cross section.
  • the end regions of the torsion bar 5 penetrate the opening 10 on both sides and have the spring levers 6.
  • the torsion bar 5 and the spring lever 6 can also be designed in one piece.
  • the openings 10 can each be a guide or a radial bearing for the respective area of the torsion bar 5.
  • Fig. 4 shows a bogie of a rail vehicle with internal spring levers 6 in a perspective basic view.
  • the fixed components of the guides or the radial bearings 11 can also be connected to the cross member 1.
  • Fig. 5 shows the bogie Fig. 4 in a principle top view.
  • the guides or the radial bearings 11 can thus be located between the axle levers 2.
  • Fig. 6 shows the bogie Fig. 4 in a basic side view.
  • the guides or radial bearings 11 are spaced apart from the rails that accommodate and guide the wheel sets 3 above the axle levers 2 so that the ends of the spring levers 6 act on the end areas of the axle levers 2 and thus on the axle bearings 4.
  • a guide or a radial bearing 11 two guides or two radial bearings can also be arranged at a distance from one another, so that the spring lever 6 can be located between them.
  • At least one damping body made of an elastomer, which can in particular consist of rubber.
  • the cross member 1 represents a base body with the links for the axle lever joints 9 and with fastening elements for attachments.
