Definitions
- Compressor in particular for vehicle air conditioning systems
- Compressor in particular for air conditioning systems of motor vehicles, preferably with CO 2 as refrigerant, with a housing and a housing arranged in the compressor unit for sucking, compressing and conveying the refrigerant, wherein the compressor unit connected to at least one suction and one pressure connection, fixed cylinder block , Axially displaceable piston, a drive shaft and centered by the drive shaft and by means of a drive shaft fixed to the guide element axially and / or tangentially supported adjusting disk, wherein the adjusting is axially displaceable to the drive shaft by means of an adjusting and the piston with the interposition of sliding shoes with the Ver adjusting disc are in operative connection.
- Such a generic compressor is known from DE 199 12 006 A1.
- the guide element which is designed as a guide arm, has at its end a guide body which is cylindrical or crowned.
- the guide body corresponds directly to the inner wall of an opening in the adjusting disk, wherein both pivoting movements and sliding movements are to be executed, since the center of the adjusting disk is displaceably guided on a drive shaft of the compressor. It has been shown that in particular in a compressor for an air conditioner with CO 2 as a refrigerant, the design and pairing between the Guide body of the guide arm and the adjusting is not sufficiently stable and problems occur.
- the object of the invention is therefore to provide an air conditioning compressor or a pairing guide element and adjusting available, the / the high operating forces of up to 5,000 N durable endures and beyond can be easily and inexpensively made available.
- the guide element is designed as a bolt which has a ball head at its end facing away from the drive shaft and that the ball head is surrounded by a ring which is arranged in a bore of the adjusting disc.
- the bolt and the ring made of hardened material, preferably made of steel, wherein the ball head is ground or hard turned executed.
- the ring has a calotte, which is adapted to the ball head and surrounds it, preferably partially. This refinement results in surface pressures which are manageable and bearable both between the ball and in the dome and between the ring and the bore in the adjusting disk.
- dome and hole in the adjusting optimal lubrication between the ball and dome is possible, which leads to a small game, which in turn results in a good adjustment of the adjustment.
- the ring is provided with a longitudinal slot and has such an elasticity that it can be pushed onto the ball head. This allows easy mounting of the ring with dome on the ball head. By a precise guidance of the ring in the bore of the adjusting results in a virtually backlash-free power transmission between the bolt and the adjusting disc.
- the dome of the ring is shortened on one side so far and the ring and possibly also the ball head have such elasticity that the ring is pushed onto the ball head.
- FIG. 2 shows a section corresponding to FIG. 1, in which the compressor unit is in a lifting position and can generate compressor power
- Figure 3 a bolt on an enlarged scale with a slotted ring
- FIG. 4 shows a bolt according to FIG. 3 with an unthreaded ring.
- FIGS. 1 to 4 designates a drive shaft, which is not shown in more detail, arranged and mounted in a compressor housing.
- a designated 2 bolt is attached, which has a ball head 3 at its free end.
- the ball head 3 is enclosed by the cap 4 of a ring 5.
- the ring is guided in a radially slidable manner in a bore of an adjusting disk 6, wherein the adjusting disk 6, not shown in more detail, is centered on the drive shaft 1.
- an adjusting sleeve 7 is arranged, which is part of an adjusting unit, not shown.
- the center of the adjusting 6 can be moved relative to the drive shaft 1 and thus also with respect to the ball head 3 and thus the angle of the adjusting disc 6 relative to the axis of the drive shaft 1 can be adjusted.
- the stroke of the compressor unit of the compressor is variable.
- the pistons 8 with further pistons are referred to, which are arranged axially displaceable in a cylinder block, not shown.
- the cylinder block is fixed.
- the pistons 8 have at their ends Kalottenköpfe 9, in which sliding shoes 10 are mounted, which are guided on the outer surfaces of the adjusting plate 6 slidably.
- the ring 5 together with the cap 4 has a longitudinal slot 11, so that the ring can be widened so far during assembly that it can be pushed over the ball head 3.
- the ring 5 according to Figure 4 has a cap 4, which does not entirely surrounds the ball head 3 on the one hand, but somewhat shortened and widened in such a way that the ring 5 is pushed without a slot on the ball head 3 of the bolt 2 can be.
