Definitions

  • the invention relates to a chassis for rail vehicles according to the preamble of claim 1.
  • Hiebei is particularly intended for low-floor, street and local railways of any gauge, in which the chassis, preferably a single-wheel chassis, is arranged at an articulated connection point between the ends of two adjacent carriages and is provided with its own drive, the chassis being expediently a portal chassis, in which transversely to the direction of travel opposite wheels are connected by a portal, portal scaffolding or the like, which forms part of the passage between successive cars.
  • the chassis preferably a single-wheel chassis
  • EP-A-0 443 309 shows a single wheel undercarriage for a rail vehicle with an engine and a transmission, the engine being arranged above the transmission.
  • EP-A-0 413 337 is concerned with the reduction of shocks, in particular shock maxima, which are transmitted from the wheel to the rotor of the motor. To solve the above problem, it is proposed to create a single running gear, an elastic ring permitting relative movement being provided between the motor and the wheel.
  • EP-A10457 106 shows an independent wheel undercarriage for rail vehicles, in which a shaft coupling which permits relative movement between the motor and the transmission is probably provided. With this drive, a relative movement between the gear and the wheel cannot take place, so that the wheel or the wheel shaft transmits height movements to the gear and thereby impairs driving comfort.
  • the object of the invention is to provide measures by which a flexible connection between the wheel and drive block is achieved, which enables relative movements and by which the transmission of height movements to the transmission is avoided, the movement of the drive block being absorbed and prevented goes on the bike. This is to separate the mass of the engine and transmission from the wheel, which should make the unsprung masses relatively small.
  • the springs used here have the advantage of cushioning the motor-gearbox combination based on weight, independent of all other existing spring systems, in order to achieve optimal cushioning for the motor-gearbox system.
  • the movement of the drive block is therefore absorbed by the springs and the elastic coupling prevents this movement from going into the wheel.
  • the bumps of the wheel are absorbed by the elastic coupling and the suspension.
  • the system according to the invention thus serves to separate the mass of the motor-transmission from the wheel, that is to say to keep the unsprung masses relatively small.
  • the measure according to claim 2 serves to prevent superposition of vibrations of the supporting spring to a primary spring.
  • the measure according to claim 3 is used to adjust the entire system.
  • the measure according to claim 4 serves to isolate the vibrations of the drive on the chassis.
  • the measure according to claim 5 is used for fine adjustment.
  • the measure according to claim 6 serves to limit the spring travel.
  • the measure according to claim 7 is used to achieve a compact design.
  • the measure according to claim 9 supports the spring movement.
  • the 7 with a driven wheel is designated, which is mounted in a wheel housing 1 formed as a steel part on a semi-axis 2 via tapered roller bearings 3, 4.
  • a portal not shown, which is the subject of the Austrian patent (A 420/90) via pins and primary springs.
  • the semiaxis 2 is flanged to the wheel housing 1 by means of screws 8 and provided at its end with a threaded part 9, on which a nut 5 is screwed, which fixes the wheel 7 to the semiaxis 2 with a preload via the tapered roller bearings 3, 4.
  • the wheel 7 consists of a wheel body with rubber-sprung wheel tires.
  • a drive group B which consists of a motor 10, e.g. can be an electric motor or a hydraulic motor, and there is a transmission 11.
  • the drive block B is drivingly connected to the wheel 7 by a clutch 6, which is designed as an articulated or elastic system which allows the drive block B to move in the direction of the double arrow A.
  • This clutch 6 prevents the wheel housing 1, which is designed as a steel part, from transmitting hard impacts to the transmission 11 or the drive block B when the acceleration is very rapid.
  • the motor 10 and the gear 11 are connected via a flange 15, etc. in the form that the motor 10 comes to rest above the gear 11 and below the flange, so that the motor 10 is arranged vertically above the gear 11 and is connected to the gear by a vertical drive shaft.
  • the flange 15 is held by two springs 20, 20 'opposite one another transversely to the direction of travel, which are supported at their lower end on the bottom of an essentially C-shaped bearing block 21 or 21', which is designed as a welded construction and by means of screws 22, 22 'is attached to the wheel arch 1 or steel part.
  • a vertical bolt 24 is held in each of the two bearing blocks 21 and 21 'by means of screws 23, 23'.
  • a sleeve 28 is guided on the bolt 24 via elastic end bearings 25, 25 '.
  • the sleeve 28 is provided with an external thread, on each of which a shaft nut 27 or 27 'is screwed on both sides of the flange 5, which shaft nuts 27, 27' serve to adjust the height of the flange 15.
  • the springs 20, 20 ' are supported on their from a spring ring 26, which is clamped between flange 15 or shaft nut 27 'and spring 20 or 20' and is movable along the sleeve 28 in the direction of the double arrow A.
  • the system described which is located in the bearing block 21 or 21 ', enables height adjustment in the direction of the double arrow A within the scope of the spring travel.
  • the rubber rings 31, 31 ' serve as end stops to limit this movement.
  • the ground connection of the motor 10 with the rail is advantageously made in that the current bridge between the motor 10 and the rail is closed via the earth cable connection 50 on the housing of the transmission, a conventional grounding socket 40 with grounding contact brushes 45, the drive shaft 12 and the wheel 7.
  • This avoids the usual grounding brushes acting directly on the wheel, which can exert different influences on the opposite wheels over the course of their service life. Rather, the already existing connection between the drive shaft 12 and the wheel 7 is used to close the current bridge and to avoid faulty lines.
  • the rigid part of the grounding brushes is mounted with the cover for the mounting of the drive shaft 12 and the rotating part directly on this shaft 12.
  • the shaft 12 conducts the current a short distance from the grounding contact brushes 45 until a connection to a flexible grounding rope 41 which rotates with the shaft 12 is reached.
  • This grounding cable 41 establishes the conductive connection between the shaft 12 and the wheel 7 in that it is connected to the cover 42 of the wheel bearing.
  • the grounding variant described has the advantage that it can be removed quickly and easily, as a result of which the internal components are easily and quickly accessible.
