Definitions

  • the invention relates to a device for compensating for undesirable steering torques on wheels with brakes of rail vehicles in particular, wherein a turning circumferential force that is proportional to the circumference of a braked wheel and is determined by the circumferential wheel force and steering roller radius is applied to the wheel in question from the outside.
  • the known construction cannot come into play if it is a non-driven wheel or if there is no transmission between the drive shaft and the wheel.
  • the present construction is therefore based on the object, even in this case, when a brake is arranged on the wheel, to obtain a compensation of the steering torque and to provide a device which can be used with any type of brake, such as block, disc, drum and / or other brakes, e.g. hydro or electrodynamic brakes, work safely and can also be used on small wheels.
  • any type of brake such as block, disc, drum and / or other brakes, e.g. hydro or electrodynamic brakes, work safely and can also be used on small wheels.
  • a compensation body is freely rotatable about the wheel axis, on which the reaction torque of a brake with brake shoes or the reaction torque of a hydro- and / or electrodynamic brake is supported, and which on the other hand a known, in both directions effective and articulated torque support is connected to the axle bridge.
  • the advantage of this device according to the invention lies primarily in the fact that the device can be used not only with all wheel sizes, but also with any type of brake, provided that it acts on the wheel or on a part connected to the wheel.
  • a brake pad 12 is pressed against the wheel tire 13 to brake the wheel 11.
  • the wheel 11 is mounted in a known manner with bearings on the steering knuckle 14 so as to be rotatable about the wheel axis, the steering knuckle 14 being mounted in the axle bridge 16 about a pivot axis 15 which is perpendicular to the wheel axis and which is in turn connected to the chassis frame 23.
  • a compensation body 17 is rotatably supported about the wheel axis with bearings and the brake pad 12 is supported on the compensation body 17 via a lever 18.
  • a torque support 19 which consists of a Fork piece 2o, which comprises a ball head 21 which is fixedly arranged on the axle bridge 16 with a lever 22.
  • the reaction torque of the brake is transmitted in this way to the axle bridge 16 via the compensation body 17 and the torque support 19.
  • this torque support can also consist of two cams, which are arranged on the axle bridge 16, between which a cam attached to the compensation body 17 extends.
  • a brake disk 24 is firmly connected to the wheel 11, the brake disk being able to be designed in a known manner as a solid disk or as an internally ventilated disk.
  • a divided or undivided brake shoe 25 is attached to both sides of the brake disk 24, which is supported by pressure elements such as pressure pistons, brake caliper levers or the like. are pressed against the brake disc 24 when the vehicle is to be braked.
  • What is essential here is the fact that the braking reaction force acting on the brake shoes and acting in the circumferential direction is introduced either directly or via intermediate lever 26 into the compensation body 17, which in turn is provided via the torque support 19, which consists of a fork 20, which comprises a ball head 21, is articulated to the axle bridge 16.
  • the braking reaction torque which is introduced into the compensation body causes a circumferential force in the active surfaces of the torque support which, with its lever arm to the pivot axis of the steering knuckle, generates a compensating torque which counteracts the steering torque formed from the braking force on the wheel circumference and the steering roller radius.
  • the torque support can also be from two intermeshing bevel gears or segments thereof are formed, one gear being connected to the axle bridge 14 and the other bevel gear or a segment thereof being connected to the compensation body 17.
  • the invention can be used in all known brake systems, as long as it is ensured that the braking reaction torque is directed to the axle bridge via a compensation body which is freely rotatable in the steering knuckle or in the wheel and an articulated torque support.
  • the compensation body does not necessarily have to be mounted in the steering knuckle, but it can also be freely rotatable in the wheel about the wheel axis.
