Abstract[English]
A crankshaft assembly for a housing of an air compressor of an air supply and/or treatment system for a braking system of commercial vehicles comprises a compressor housing (3) of an air compressor; a crankshaft (1) which is rotatably mounted within the compressor housing (3); and at least one roller bearing (2a, 2b) which is configured such that it rotatably supports the crankshaft (1); wherein means are provided for enabling an axial movement of the at least one roller bearing (2b) within the compressor housing (3) together with an axial movement of the crankshaft (1) or of parts of the crankshaft (1). The crankshaft assembly is further configured such that the housing (3) comprises an inner, axially extending surface (7.1); the bearing (2b) comprises a radially outer race (4b) and a radially inner race (5b), wherein the radially inner race (5b) is mounted on the crankshaft (1); and the means for enabling an axial movement of the bearing (2b) within the housing (3) comprise a disc (8) which is disposed between the inner surface (7.1) of the housing (3) and the radially outer race (4b) of the bearing (2b), wherein the radially outer race (4b) of the bearing (2b) is mounted on the disc (8). The disc (8) comprises means (9, 9b) which are configured to lock the disc (8) in the circumferential direction such that the disc (8) is not able to rotate, particularly when the crankshaft (1) rotates. The locking means (9, 9b) comprise a protrusion (9, 9b) which extends radially outward from a radially outer edge (8b) of disc (8); and the inner surface (7.1) of the housing (3) comprises a recess (10) into which the protrusion (9, 9b) of disc (8) can engage.[French]
Un ensemble vilebrequin pour un carter d'un compresseur d'air d'un système d'alimentation et/ou de traitement d'air pour un système de freinage de véhicules utilitaires comprend un carter de compresseur (3) d'un compresseur d'air ; un vilebrequin (1) qui est monté rotatif à l'intérieur du carter de compresseur (3) ; et au moins un palier à rouleaux (2a, 2b) qui est conçu de sorte qu'il supporte de manière rotative le vilebrequin (1) ; des moyens étant prévus pour permettre un mouvement axial de l'au moins un palier à rouleaux (2b) à l'intérieur du carter de compresseur (3) conjointement avec un mouvement axial du vilebrequin (1) ou de parties du vilebrequin (1). L'ensemble vilebrequin est en outre conçu de sorte que le carter (3) comprend une surface intérieure s'étendant axialement (7.1) ; le palier (2b) comprend une bague radialement extérieure (4b) et une bague radialement intérieure (5b), la bague radialement intérieure (5b) étant montée sur le vilebrequin (1) ; et les moyens pour permettre un mouvement axial du palier (2b) à l'intérieur du carter (3) comprennent un disque (8) qui est disposé entre la surface intérieure (7.1) du carter (3) et la bague radialement extérieure (4b) du palier (2b), la bague radialement extérieure (4b) du palier (2b) étant montée sur le disque (8). Le disque (8) comprend des moyens (9, 9b) configurés pour verrouiller le disque (8) dans le sens circonférentiel de sorte que le disque (8) ne puisse pas tourner, notamment lorsque le vilebrequin (1) tourne. Les moyens de verrouillage (9, 9b) comprennent une saillie (9, 9b) qui s'étend radialement vers l'extérieur à partir d'un bord radialement extérieur (8b) du disque (8) ; et la surface intérieure (7.1) du carter (3) comprend un évidement (10) dans lequel la saillie (9, 9b) du disque (8) peut venir en prise.
