Definitions

  • the invention relates to an anti-lock device according to the preamble of claim 1.
  • a disadvantage of all previously known types of sensor installations or fastenings is that the installation of the sensor and the part which interacts with it, rotating with the wheel, complicate and increase the cost of mounting the vehicle, and that the sensor is partially freely accessible on the wheel suspension in an encapsulated manner is attached and the cables hang relatively freely.
  • both the sensor as well as the cable are exposed to heavy loads, which must be compensated for by a correspondingly robust construction.
  • Fig. 1 is a diagonally illustrated wheel bearing cartridge with a sensor with partial section
  • Fig. 2 shows the wheel bearing cartridge according to Fig. 1 in an axial view.
  • Fig. 1 shows a wheel bearing cartridge 3 with a vertical and a horizontal section.
  • the wheel bearing cartridge 3 consists essentially of one by means of the screw holes 4 with the square standing flange 1 to be connected to the vehicle and a round rotating flange 2 to be fastened to the wheel by means of the screw holes 5.
  • the rotating flange 2 has an axial extension which extends into the standing flange and there axially by means of a ball bearing is guided.
  • the two flanges 1 and 2 are connected to one another for rotation via the ball bearings 6, 7.
  • the ball bearing itself is closed to the outside by means of a cover ring 10 on the one hand and by means of a seal 15 on the other hand.
  • the axial extension of the rotating flange 2, designed as a ring gear 8, has two guide grooves for the balls 6 and 7 on its circumference. Between these grooves, the ring gear is thickened again and has axially extending grooves 12 which run on the outside of the ring gear 8. Grooves 11 are also arranged on the inside of the ring gear and serve to secure the rotation of the flange 2 with respect to the wheel axis.
  • An anti-lock sensor 9 is sunk in a material projection 13 of the standing flange 1 and in the flange 1 itself, which is arranged such that the outer grooves 12 of the ring gear 8 rotate past the sensor 16 of the sensor when the flange 2 rotates.
  • the rotating ribs 12 generate 9 pulses in the sensor, the frequency of which is proportional to the speed of the wheel. This frequency is differentiated in an electronic computing and control device (not shown) and a signal for the temporal change in the wheel speed is obtained therefrom.
  • the same wheel bearing cartridge is shown in an axial view in FIG. 2, the same parts being provided with the same reference numerals as in FIG. 1.
  • the ring gear 8 is arranged in the interior of the angular flange 1 and has inner grooves 11 for receiving the wheel axle and outer grooves 12 for interaction with the sensor 9.
  • the pulse duty factor of the outer grooves 12 can vary and must be adapted to the sensor or its resolution.
  • the number of grooves 12 over the entire circumference of the ring gear 8 can also vary within certain limits dependent on the sensor, the maximum number depending on the sensitivity of the sensor and the minimum number on the desired measurable minimum speed of the wheel rotation.
  • the arrangement of the sensor 9 in a material projection of the standing flange 1 is chosen, for example, and is in no way to be considered restrictive.
  • the sensor could just as well be arranged tangentially to the grooves of the balls 6 or 7, with each passing ball generating a pulse.

Abstract

Le dispositif antiblocage pour roue comporte dans le palier de la roue (3) un detecteur (9) du ralentissement de la roue. La partie rotative (8) du palier de la roue (3) presente des nervures exterieures (12), ou le palier de la roue (3) comporte des billes ou des rouleaux (6, 7) qui pendant la rotation induisent dans le detecteur (9) des impulsions de frequence proportionnelle au nombre de revolutions de la roue.
