Definitions

  • the present invention relates to a rolling cam gear.
  • Rolling gear drives have two rolling curves that are in linear contact with each other and generally roll on one another without sliding.
  • DE 100 02 455 A1 discloses a stabilizer arrangement for the undercarriage of a vehicle, with an actuator integrated between two stabilizer halves and, if necessary, rotating them against one another by an angle of rotation, which consists of an adjusting drive and a transmission connected downstream of the latter.
  • the transmission is designed in the form of a cam track gear, with two cam track supports assigned to the stabilizer halves, in the cam tracks of which differ from one another, a coupling element which is displaceable along these cam tracks by means of the adjusting drive is guided.
  • the cam track carriers are designed essentially in the shape of a hollow cylinder, while the coupling element can be displaced along the longitudinal axis of the hollow cylinders arranged coaxially to one another.
  • the coupling element serves as a roller carrier on which cam rollers are rotatably mounted. These cam rollers roll on the cam tracks with their rolling surface.
  • the object of the present invention is to ensure a perfect rolling of the cam roller on the cam track in a rolling cam mechanism according to the preamble of claim 1.
  • this object is achieved in that a lubricating path is arranged along the curved path, from which lubricant contacts the rolling surface. before the cam roller arrives.
  • a lubricating path is arranged along the curved path, from which lubricant contacts the rolling surface. before the cam roller arrives.
  • the transfer of the lubricant to the rolling surface of the cam roller does not only take place at the beginning or end of the cam track, but at least at a plurality of intermediate points between the beginning and the end of the cam track.
  • This transfer of lubricant preferably takes place continuously between the start point and the end point of the lubrication track, so that perfect lubrication is ensured by the complete extension of the cam track.
  • a cam track carrier is preferably provided with both the cam track and the lubrication track, the lubrication track and the cam track facing one another and being able to be arranged at a parallel distance from one another.
  • Such an arrangement can be implemented in a favorable manner in the stabilizer arrangement known from DE 100 02 455 A1.
  • two cam rollers are rotatably mounted on a cylinder axis, one outer cam roller rolling on an approximately S-shaped cam track of the outer hollow cylinder and the inner cam roller rolling on a cam track of the other hollow cylinder arranged coaxially to the longitudinal axis of the stabilizer ,
  • the two hollow cylinders have slots in their lateral surface, one of the slot walls facing one another having the cam track and the other slot wall having the lubricating track according to the invention.
  • a starting position for the cam rollers is a starting position for the cam rollers. Starting from this neutral position, roll movements can be compensated for by moving the cam rollers along the cam tracks.
  • a cam track and a lubrication track are preferably arranged opposite one another.
  • the distance between the lubrication track and the cam track can be the same size or smaller than the diameter of the cam roller. If the cam roller rolls along the cam track, it is also in contact with the opposite lubrication track and can take over lubricant on the rolling surface while sliding past the lubrication track.
  • a lubrication device which has a preferably band-shaped lubricant dispenser which has the lubrication track.
  • the lubrication device can have a lubricant reservoir to which the lubricant dispenser is connected.
  • a particularly easy to manufacture lubrication device, in which the lubricant reservoir is also the lubricant dispenser, is provided if the lubricant dispenser is formed from a capillary material, for example from a porous material. Lubricant can be embedded in this porous material, the capillary action preventing the lubricant dispenser from running dry. This material can have elastic properties, so that the cam roller elastically deforms the lubricant dispenser while sliding along the lubrication track, lubricant being released onto the rolling surface of the cam roller.
  • the cam track carrier preferably has a receptacle for the band-shaped lubricant dispenser, the lubricant dispenser being inserted into the receptacle.
  • FIG. 1 shows a cross section through a roller cam mechanism according to the invention
  • FIG. 2 shows a section of the rolling cam mechanism according to the invention from FIG. 1 in a schematic illustration
  • FIG. 3 shows a roll stabilizer of a motor vehicle, which is part of the prior art and is provided with a rolling cam mechanism.
  • the roll stabilizer shown in FIG. 3 is identical to the roll stabilizer disclosed in DE 100 02 455 A1 in FIG. 4 in connection with columns 3 and 4.
  • This roll stabilizer is integrated between two stabilizer halves 1, 2 of a motor vehicle.
  • the roll stabilizer comprises an actuator 3, which comprises a motor 4 and an actuator 5.
  • the actuator 5 comprises 2 hollow cylindrical housing parts 6, 7, nested one inside the other, one of which is on the outside and the other of which is arranged on the inside.
  • the two housing parts 6, 7 are arranged rotatable relative to one another.
  • the outer housing part 6 has a plurality of approximately S-shaped slots 8 which are distributed over the circumference.
  • the inner housing part 7 has a plurality of linearly extending slots 9 which are distributed over the circumference.
  • a roller carrier 10 which is displaceable in the longitudinal directions and rotatable about the longitudinal axis, has a plurality of pins distributed over the circumference, on each of which two cam rollers 11, 12 are rotatably mounted.
  • One cam roller 11 engages in the S-shaped slot 8 of the outer housing part 6 and the other cam roller 12 engages in the longitudinally extending slot 9 of the inner housing part 7.
  • the slots 8, 9 are delimited by slot walls facing one another and arranged parallel to one another. In the longitudinal directions, the slots 8, 9 are delimited by slot ends.
  • the roller carrier 10 is positioned approximately centrally between the slot ends in the slots 8, 9. tioniert. From this starting position, the roller carrier 10 can be moved both in one and in the opposite longitudinal direction.
  • One and the same diaphragm wall of a slot can be divided into two sections, which are located on both sides of the starting position. One section serves as a load-transmitting cam track on which the cam rollers 11, 12 can roll. The other section remains largely unloaded.
  • the cam roller carrier 10 When the cam roller carrier 10 is displaced, the two housing parts 6, 7 are rotated relative to one another, whereby a rotation of the stabilizer halves 1, 2 which compensates for the roll tendency is initiated.
  • the roller cam mechanism provided here thus serves to rotate the housing parts 6, 7 relative to one another in order to introduce a reinforcing torque into the stabilizer halves 1, 2.
  • Figure 1 shows in cross section an inventive roller cam mechanism, which corresponds in its basic structure to the known roller cam mechanism described above.
  • the rolling cam mechanism according to the invention is also installed in a roll stabilizer.
  • Components of the roll stabilizer and roller cam mechanism according to the invention which correspond to components of the known roll stabilizer and roller cam mechanism described above are provided with the same reference numerals below.
  • cam rollers 11, 12 rotatably arranged on the roller carrier 10 also engage in slots 13, 14 which are formed on the housing parts 6, 7.
  • the slots 13, 14 are clearly shown in FIG. 2 in a schematic illustration together with the cam rollers 11, 12, which are also only indicated.
  • the cam rollers 11, 12 are arranged approximately centrally in the slots 13, 14 between their slot ends. This central arrangement is called the starting position. Starting from this starting position, the roller carrier 10 with the cam rollers 11, 12 rotatably arranged thereon can be displaced longitudinally on both sides in the slots 13, 14. Under this shift, the two housing parts 6, 7 are forcibly rotated relative to one another.
  • the slots 13, 14 are bounded by slot walls facing one another and arranged parallel to one another.
  • the slot walls of both slots 13, 14 are each subdivided into a lubrication track 15, 16 and a cam track 17, 18.
  • the limit is approximately in the region of the illustrated starting position of the cam rollers 11, 12.
  • the cam rollers 11, 12 When the roller carrier 10 is displaced, the cam rollers 11, 12 also slide past the lubrication tracks 15, 16 which lie opposite the cam tracks 17, 18. In this sliding contact, lubricant is released from the lubrication track 15, 16 to the rolling surfaces of the cam rollers 11, 12.
  • FIG. 1 shows receptacles 19, 20 provided on the housing parts 6, 7, which are approximately groove-shaped and parallel to the slot walls.
  • Band-shaped lubricant dispensers 21 made of capillary material are used in these receptacles 19, 20. In the present case, this capillary material is porous, lubricant being embedded in the material.
  • the surfaces of the band-shaped lubricant dispensers facing the slots 13, 14 also form the lubrication tracks 15, 16.
  • the material of the band-shaped lubricant dispenser 21 can also be elastically deformed, if necessary. In this way, lubrication for perfect rolling contact of the cam rollers 11, 12 with the cam tracks 17, 18 is ensured.
  • the band-shaped lubricant dispenser 21 in the present case also forms a lubricant store due to its capillary design.
