Said drive sprocket (10) is configured to engage with said endless track (E). Said drive sprocket member (S1, S2) further comprises a support member (20) for said drive sprocket (10). Said drive sprocket (10) is divided into at least two arc shaped drive sprocket parts (10A, 10B). Each drive sprocket part (10A, 10B), in a non engaged state of a drive sprocket part with respect to said endless track, is configured to be exchangeable. Said arrangement (A) comprises a guiding configuration (G1, G2) comprising a first guiding member (G1) circumferentially distributed around the support member (20) and a second guiding member (G2) circumferentially distributed around the respective drive sprocket part (10A, 10B) for facilitating reassembling the drive sprocket (10). The present invention also relates to a tracked vehicle.

The present invention relates to a fastening arrangement of a drive wheel (DW) for an endless track (E) of a tracked vehicle (V) the drive wheel (DW) comprising a hub member (H) and a drive sprocket member (S1, S2). Said drive sprocket member comprises a set of teeth (10) arranged around the circumference of said drive sprocket member (S1, S2), said teeth (10) being configured to engage with said endless track (E). Said drive sprocket member (S1, S2) further comprises a support member (20) for teeth (10) of said drive sprocket member. Said teeth (10) are configured to be removably attached to said support member (20). Said fastening arrangement is configured for fastening one or more teeth (10) of the set of teeth (10) to the support member (20). Said fastening arrangement comprises a set of dovetail shaped recesses (22) of said support member (20). Each dovetail shaped recess (22) is configured to receive a locking portion (12) of one or more teeth (10) so as to provide a locking function for said one or more teeth (10). The present invention also relates a tracked vehicle.

A work machine includes a frame including an axle and an arm, a track undercarriage assembly including an undercarriage assembly connected to the arm, a drive assembly operably attached to the axle, and a track belt mounted on the drive assembly. The undercarriage assembly and the drive assembly are each configured for lateral adjustment relative to a longitudinal centerline of the frame from a first position to a second position. The drive assembly includes a drive sprocket that is assembled with the axle in a first configuration to laterally adjust the drive assembly towards the first position and a second configuration to laterally adjust the drive assembly towards the second position. The undercarriage assembly includes an undercarriage frame attached to the arm, wherein the undercarriage frame and the arm are adjustably coupled to allow the undercarriage frame to be movably adjusted between the first and the second positions.

A track support member and drive assembly are disclosed. The drive assembly includes the track support member, an axle housing, driveshaft, hub, drive wheel, track drive frame, rollers and track. The driveshaft extends through the axle housing. The track support member is connected to the axle housing, and the driveshaft extends through the track support member. The hub rotates with the driveshaft, and the drive wheel. The drive frame is connected to the track support member, and the rollers are connected to the drive frame. The track is connected to the drive wheel and rollers. Rotation of the driveshaft rotates the hub and drive wheel which rotates the track about the drive wheel and rollers. The track support member can be a single integrated piece including an attachment ring for connecting to the axle housing, and undercarriage support arm(s) for connecting to the track drive frame.

The sprocket member keeps the sprocket centered within the link box while the notches or cut-outs allow mud, dirt, or other material to move out of the link box formed of the track chain assembly by two track bushings and two track links that form a rectangular shaped perimeter. The spacing provided by the wings of the sprocket member reduce wear on the track links near a track bushing and track link interface such as a press-fit connection by spacing the lugs of the sprocket member away from the interface.
