Definitions

  • the invention relates to a chassis for rail vehicles, with at least a first wheel and a second wheel, at least a first wheel bearing with a first wheel bearing housing and a second wheel bearing with a second wheel bearing housing, at least one first primary spring and a second primary spring, at least one primary-sprung support structure and at least an active wheel adjusting device which has an actuator unit, a first bearing and a second bearing being provided between the at least one wheel adjusting device and the at least one support structure and a guide being provided between the at least one wheel adjusting device and the first wheel bearing housing.
  • Running gear for rail vehicles must have a high level of driving safety. This can be improved, for example, by arranging an active wheel control or wheel set control.
  • the targeted positioning of wheels or wheel sets by actively rotating them around their vertical axes is used in a known manner to prevent unstable driving conditions.
  • the active wheel control or wheel set control reduces the wear on wheels and rails.
  • an active wheel control or wheelset control makes it necessary to arrange additional components (e.g. actuators) in the chassis. Depending on how these components are mounted on the chassis, this can lead to high unsprung masses and heavy loads on the track structures and the wheel control and steering systems.
  • additional components e.g. actuators
  • High unsprung masses of a vehicle as well as a heavy load on a track can lead, for example, to high route usage charges (eg track access charges in Great Britain) which have to be paid by a vehicle operator.
  • high route usage charges eg track access charges in Great Britain
  • EP 1 569 835 B1 a wheelset guide structure with vertical, lateral and longitudinal guide elements, which guide a wheelset of a chassis in three spatial directions.
  • the longitudinal guide element is designed as a guide rod and connects a running gear frame with a wheel set bearing, ie it is mounted on the running gear frame and the wheel set bearing.
  • the EP 0 759 390 B1 discloses a chassis for a rail vehicle with a wheelset adjusting device.
  • the wheelset adjusting device has a coupling device and an adjusting device, by means of which the steering angles of wheelsets are adjusted in accordance with a curved track to be traveled through.
  • the coupling device comprises two coupling shafts mounted on a chassis frame, with which four trailing arms are connected. Each trailing arm is mounted on a wheelset bearing.
  • the DE 10 2014 214 055 A1 a chassis for a rail vehicle, in which wheel set guidance devices with wishbones are provided.
  • Each wishbone is connected to a wheelset bearing via a first bearing and to a chassis frame via a second bearing and a third bearing.
  • At least one of the bearings has a hydraulic bushing with variable longitudinal rigidity.
  • the invention is therefore based on the object of specifying a chassis that has been further developed compared to the prior art. According to the invention, this object is achieved with a chassis of the type mentioned at the outset, the at least one wheel adjusting device comprising a lever, the first bearing being arranged between the lever and the at least one support structure and a third bearing being arranged between the lever and the actuator unit.
  • the wheel adjusting device is connected to the support structure via the first bearing and the second bearing, which are arranged on the primary-sprung support structure or on adapters connected to the support structure.
  • a mounting of the wheel adjusting device on the wheel bearing housing or on a swing arm arranged between the first wheel and the support structure can be dispensed with.
  • the wheel adjusting device is mounted on the chassis with primary springs, which reduces the unsprung masses of the chassis.
  • loads on a track body and on the wheel adjusting device itself are reduced as a result.
  • Via the guide between the wheel adjusting device and the wheel bearing housing actuating forces are transmitted and the steering angle of the first wheel is set or the first wheel is guided on a track. This results in an increase in driving stability and driving comfort and a reduction in wheel and rail wear. Furthermore, acoustic advantages are also achieved.
  • Actuating forces acting on the first wheel are transmitted from the actuator unit and via the lever to the wheel bearing housing.
  • the lever brings about a favorable force transmission, whereby the actuator unit can be dimensioned compact.
  • the actuator unit has at least one pneumatic actuator.
  • FIG. 1 A section of an exemplary variant of a chassis of a rail vehicle according to the invention, shown in a side view, comprises a section of a support structure 8 and a first wheel 1 that rests on a track 19.
  • the support structure 8 is designed as a chassis frame with longitudinal members and a cross member. According to the invention, various embodiments of support structures 8 are conceivable with regard to geometry, connection technology, materials, etc.
  • the support structure 8 can be made in one piece or in several pieces. In the case of multi-part embodiments, it is possible, for example, to connect individual parts to one another in an articulated manner, etc.
  • the first wheel 1 is arranged around a transverse axis 20 and is connected to a first wheel set shaft, not shown, which runs along the transverse axis 20.
  • the first wheel bearing housing 4 is connected to a first swing arm 5, which is coupled to the support structure 8 via a first wheel guide bushing 6.
  • the first wheel bearing housing 4 itself performs the function of the first swing arm 5, i.e. is connected to the support structure 8 via the first wheel guide bushing 6, whereby the first swing arm 5 can be dispensed with.
  • the second wheel which is not visible, is connected to the first wheel set shaft.
  • the first wheel 1 together with the first wheelset shaft and the second wheel, forms a first wheelset 2.
  • the first wheel set 2 is connected to the support structure 8 via a second wheel bearing, a second wheel bearing housing, a second swing arm and a second wheel guide bushing.
  • the chassis also includes an in Fig. 1 second set of wheels, not shown, which comprises a third wheel, a fourth wheel and a second wheel set shaft.
  • the second wheel set is connected to the support structure 8 via a third wheel bearing and a fourth wheel bearing, a third wheel bearing housing and a fourth wheel bearing housing, a third swing arm and a fourth swing arm and a third wheel guide bushing and a fourth wheel guide bushing.
  • the support structure 8 is mounted on the first set of wheels 2 and the second set of wheels with primary springs.
  • a first primary spring 7 is arranged between the first wheel bearing housing 4 and the supporting structure 8, a second primary spring between the second wheel bearing housing and the supporting structure 8, a third primary spring between the third wheel bearing housing and the supporting structure 8 and a fourth between the fourth wheel bearing housing and the supporting structure 8 Primary spring.
  • the chassis has loose wheel pairs, which are often used in low-floor tram vehicles.
  • FIG. 1 The chassis shown has an external bearing. According to the invention, however, it is also conceivable for the chassis to be designed with internal bearings.
  • the actuator unit 10 has a pneumatic actuator 18 known from the prior art, which via FIG Fig. 1 Compressed air connections and compressed air lines, not shown is connected to a compressed air system of the rail vehicle.
  • the pneumatic actuator 18 comprises a cylinder and a piston. Pressures acting in the cylinder cause forces on the piston, which are transmitted via the lever 15 and act as actuating forces on the first wheel set 2.
  • the pneumatic actuator 18 is connected to a control unit (not shown) of the rail vehicle for pressure control and thus actuating force control.
  • the actuator unit 10 can also have a hydraulic actuator.
  • the lever 15 is connected to a first adapter 16 via an elastic first bearing 11, and the actuator unit 10 is connected to a second adapter 17 via an elastic second bearing 12.
  • the first adapter 16 and the second adapter 17 are welded to the support structure 8. According to the invention, however, it is also conceivable, for example, that the first adapter 16 and the second adapter 17 are screwed to the support structure 8.
  • first bearing 11 and the second bearing 12 directly on the support structure 8, i.e. to dispense with the first adapter 16 and the second adapter 17.
  • the lever 15 is connected to the actuator unit 10 via a third bearing 13 embodied as a swivel joint and passed through a sliding joint 14 which is embodied as an elastic bush and is arranged on the first swing arm 5.
  • the position of the sliding joint 14 on the first swing arm 5 is defined by the distance a.
  • the first wheel set 2 can thereby rotate about a vertical axis 21.
  • the adjustment angles of the first wheelset 2 are set, ie the orientation of the first wheelset 2 is adapted to a geometry of the track 19.
  • the distance a can be selected according to a required power transmission.
  • the pneumatic actuator 18 can be made compact.
  • wheel adjusting device 9 is connected to the support structure 8.
  • two wheel adjusting devices 9 can be arranged which apply adjusting forces to the first wheel set 2 and the second wheel set.
  • wheel adjusting devices 9 i.e. a total of four wheel adjusting devices 9, at both ends of the first wheel set 2 and the second wheel set.
  • the actuating forces to be generated are set and coordinated in the control unit with regard to their amounts and directions.
