Definitions

  • the invention deals with drive of a rail vehicle wheel with pivoted mounting on an axle housing.
  • the first solution group is characterized by a motor directly built in the wheel construction.
  • the motor thus becomes a part of unsprung mass of the vehicle and thus has negative influence on the dynamic forces between the vehicle and the rails.
  • the motor itself is exposed to high dynamic forces.
  • Patents DE 42 34 831 C1 and EP 0 464 929 A3 serve as examples of this solution.
  • the second solution group is characterized by a motor mounted separately from the wheel and sprung against the wheel. The moment transmission between the motor and the wheel is solved by joints or mechanisms exposed to wear and aging.
  • Inventions EP 0 760 305 A2 , DE 196 00420 C1 , DE 195 31 355 A1 may serve as examples of the second solution groups.
  • a single wheel drive particularly applicable to a tram wheel, mounted on an axle housing, the nature of which is based on the principle, that the driving motor is swing mounted in a suspender firmly connected with the sprung parts of a vehicle, and the driven wheel of a rail vehicle is mounted on an axle housing pin in such a manner, that there is a cavity inside the pin for location of the driving shaft of the driving motor, or for location of the driving shaft of the driving motor and an articulated joint.
  • the driving shaft of the driving motor is connected by means of an articulated joint with angular and axial flexibility with the driven wheel of the rail vehicle pivot mounted on an axle housing pin.
  • a motor suspended this way in combination with a gear box, or a motor with a gear box and friction brake or a motor with a friction brake may form a drive unit.
  • the arrangement according to the invention with a sprung driving motor or sprung driving unit will favourably influence the ratio between sprung and unsprung masses of a vehicle, which will result in lower dynamic effects between the vehicle and the rail.
  • the motor impact stress is also lower, than if it is built in a wheel, which increases reliability and life cycle of the motor.
  • Fig. 1 shows a view and cross section of a version with a ball joint
  • Fig. 2 shows a version with an articulated joint with flexible elements.
  • a driving shaft 4 of the driving motor 1 is connected by means of an angularly and axially flexible articulated joint 5 with a driver 6 mounted to the rail vehicle driven wheel 7 pivot mounted on a pin 9 of the axle housing 8.
  • the driving motor 1 is permanently connected by the driving shaft 4 and the angularly and axially flexible articulated joint 5 with the rail vehicle driven wheel 7 , so it can apply driving or braking effect on the rail vehicle driven wheel 7 .
  • the reactive moment of the driving or braking effect is transferred to the sprung parts of the vehicle through the swing suspender 2.
  • Fig. 2 shows wheel drive with swing mounting of the motor 1 with application of an articulated joint 5 with flexible elements.
  • Single wheel drive particularly applicable to a tram wheel, with a swinging driving motor or a swinging driving unit is applicable for newly manufactured vehicles with electric drive or electric power transmission.
  • the arrangement is particularly suitable for low-floor vehicles, as the drive parts do not substantially interfere the space between wheels.
