Die vorliegende Erfindung betrifft eine Antriebsvorrichtung für Tandemachsen eines Fahrzeuges oder einer selbstfahrenden Arbeitsmaschine, die einen fest an einem Fahrzeugrahmen oder Rahmen der Arbeitsmaschine angeordneten Achsträger (12) und einen drehbar am Achsträger (12) gelagerten Tandemkasten (14) umfasst, sowie mit mindestens einer Antriebswelle (16), wobei das Antriebsmoment der Antriebswelle (16) über ein Doppelplanetengetriebe (18) bestehen aus einem ersten antriebsseitigen Planetengetriebe (20) mit einem ersten Sonnenrad (24) und ersten Planetenrädern (26) und einem abtriebsseitigen Planetengetriebe (22) mit einem zweiten Sonnenrad (28) und zweiten Planetenrädern (30) auf einen Tandemachsenantrieb (32) übertragen wird und die ersten und zweiten Planetenräder (26, 30) über jeweils eine Planetenwelle (34) miteinander verbunden sind, wobei die ersten Planetenräder (26) gegen einen ersten, mit dem Achsträger (12) verbundenen Zahnkranz (36) und die zweiten Planetenräder gegen einen zweiten, im Tandemkasten (14) angeordneten Zahnkranz (38) abgestützt sind. Erfindungsgemäß ist der zweite Zahnkranz (38) auf den zweiten Planetenrädern (30) verschiebbar ausgebildet, derart, dass er in einer ersten Schaltstellung (EIN) der Antriebsvorrichtung (10) torsionsfest mit dem Tandemkasten (14) verbunden ist und in einer zweiten Schaltstellung (AUS) vom Tandemkasten (14) gelöst und mit dem ersten Zahnkranz (36) verbunden ist. Die Erfindung betrifft weiterhin ein Verfahren zum Antrieb von Tandemachsen eines Fahrzeuges oder einer selbstfahrenden Arbeitsmaschine.

Disclosed is a mounting structure of a carrier roller (8) that can decrease vibration occurred in an endless track chain assembly because a location of a carrier roller (8) installed on a lower frame can be controlled. According to the present invention, the mounting structure of the carrier roller (8) is a mounting structure of a carrier roller installed on a lower frame (2) for supporting an upper side of an endless track chain assembly (1). Further, the mounting structure of the carrier roller (8) includes a mounting part (10) installed on the lower frame, a support part (20) coupled to the mounting part (10) so as to enable its location to be controlled, and a carrier roller (30) coupled to the support part (20) for supporting the endless track chain assembly (1).

The invention relates to the mechanical adapter assembly (1) of the transmission line for a motor vehicle (2) comprising shafts (3, 4, 5) rotatably guided by different bearings and couplings for driving said different shafts (3, 4, 5). Said inventive assembly is characterised in that it also comprises a differential carrier (6) which is used in the form of a crankcase containing the oil for lubricating the different bearings and couplings and provided with a front aperture (7), a front plate (8) integrating a pump (9) and making it possible to close said front aperture (7) of the differential support (6) and an attached pipe section (10) which supplies the oil from said front plate (7) to the differential support (6) and interacts with additional fixtures (11, 12 ) to the front plate (8) and the differential carrier (6).

A tandem axle assembly includes a forward drive axle coupled to a rear drive axle with a connecting driveshaft. An inter-axle differential (IAD) located in a carrier assembly for the forward drive axle takes driving input and splits the input between the forward and rear drive axles. The IAD transfers driving force to a ring and pinion gear assembly in the carrier assembly for the forward drive axle and transfers driving force to a thru-shaft that is operably coupled to drive the rear drive axle via the connecting driveshaft. The pinion gear includes a first portion defining a pinion gear head and a second portion defining a hollow pinion support shaft that extends into the IAD. The pinion support shaft applies a thrust load to an IAD bearing via an IAD gear assembly to permit reverse load sharing. The thru-shaft extends through the hollow pinion support shaft such that the thru-shaft and the pinion gear rotate about a common axis. The ring and pinion gear assembly are coupled to a differential assembly that drives a pair of axle shafts. The differential assembly includes first and second case halves that attach to each other at an interface to define a case split line. The ring gear, first case half, and second case half are all connected together via a single bolted joint with the case split line being located behind the ring gear.

A differential gear for distribution of torque between a forward driven wheel shaft and a rear driven wheel shaft on a vehicle in which the rear wheel shaft can be raised has an input shaft (3) which via differential pinions (6) is in engagement with a rear differential wheel (7) connected to an output shaft (4). The input shaft (3) and the rear differential wheel (7) are mutually supported via a bearing (15) which transmits axial forces between them. This bearing is fitted with preloading to eliminate axial play.

摘要:
A lubricant pump (82) of the gerotor type is mounted concentrically over the output shaft (24) of the leading axle (76) in a tandem drive axle arrangement having in inter-axle power dividing differential (36). The outer rotor (88) of the pump (82) is connected by an annular drive band (120) to the differential carrier (38) to assure full time pump operation. Passages (114,134) are provided for flow through an externally mounted filter.
