Reciprocating-piston machine, in particular two-stage or multi-stage piston compressor, compressed-air supply installation, compressed-air supply system and vehicle, in particular passenger car, having a compressed-air supply installation

Abstract

The invention relates to a reciprocating-piston machine (400), in particular a two-stage or multi-stage piston compressor (400), or two-cylinder or multi-cylinder piston compressors, having: at leastone cylinder (410, 420) and at least one first piston (K1) associated with the cylinder (420) and a second piston (K2) associated with the or a cylinder (410), wherein during operation the pistons (K1, K2) are deflected in a cylinder displacement space (411, 421) of the at least one cylinder (410, 420); a crankshaft (430), which can be driven during operation and which has an eccentric crankshaftjournal (432) and a drive shaft coupling (431), which is designed for coupling a drive shaft (501) of a drive motor (M) in order to drive the crankshaft (432); a first connecting rod (P1) designed todeflect the first piston (K1); a second connecting rod (P2) designed to deflect the second piston (K2); and a bearing pin (L2B), around which the first connecting rod (P1) and the second connecting rod (P2) can rotate, wherein the first connecting rod (P1) can be moved by means of the eccentric crankshaft journal (432) and the second connecting rod (P2) can be moved by means of the bearing pin (L2B), and characterized in that at least one, in particular a first, elastomer element (L2; L2E; L2E2; L2Ea, L2Eb; L2ES) elastically supporting the bearing pin (L2B) and the first connecting rod (P1) against each other is arranged between the bearing pin (L2B) and the first connecting rod (P1), and / or the at least one or at least one, in particular a second, elastomer element (L2; L2E; L2E1, L2E3; L2Ea, L2Eb; L2ES) elastically supporting the bearing pin (L2B) and the second connecting rod (P2) against each other is arranged between the bearing pin (L2B) and the second connecting rod (P2).

Description

technical field [0001] The invention relates to a reciprocating piston machine, in particular a two-stage or multi-stage piston compressor, according to the preamble of claim 1 . Furthermore, the invention relates to a compressed air supply system and a compressed air supply system as well as a vehicle, in particular a passenger vehicle, having a reciprocating piston machine, in particular a piston compressor. Background technique [0002] Compressed air supply systems are used in all types of vehicles, in particular for supplying compressed air to air spring systems of passenger vehicles or commercial vehicles. The air spring system can also include level adjustment devices with which the distance between the axle and the vehicle body can be set. The air spring device of the pneumatic compressed air supply system mentioned at the beginning of this article includes a certain number of air bladders that are pneumatically connected to a common line (path), and the air bladder...

Problems solved by technology

[0010] As recognized by the present invention, a solution of this type has the danger of relatively high sound generation and structure-borne sound transmission due to the connecting rod drive into the compressor drive motor and thus also outwardly.
