A track system for a work vehicle comprises a driving wheel (7), an undercarriage beam (14) hinged to a frame (2) of the vehicle, at least one idler wheel (9), at least a first and a second roller wheels (11, 12) attached to the undercarriage beam (14) and a rubber track (6) wound about at least driving wheel (7), idler wheel (9), first and second roller wheels (11, 12). The track system further comprises a tilting linkage (20) to attach first and second roller wheels (11, 12) to the undercarriage beam (14) and a roller wheel motion limiter (21) attached to the tilting linkage (20) such that, during tilting of the linkage when a load is applied on one roller wheel, a loading action is applied from the first to second roller wheel (11, 12) through the limiter (21) to increase the pressure uniformity of the track on the ground.
A rubber tracked work vehicle comprises a suspension (3) having a driving wheel (7), an undercarriage beam (14) hinged to a frame (2) of the vehicle, at least one idler wheel (9), at least a first, a second and a third roller wheels (11, 12, 13) attached to the undercarriage beam (14) and a track (6) wound about at least driving wheel (7), idler wheel (9), roller wheels (11, 12, 13). Furthermore a tilting linkage (15) is provided having an intermediate rocker (21) attached to the undercarriage beam (14) via a first and a second rocker (20, 22), and an elastic or visco-elastic connection (23) to connect intermediate rocker (21) to first and second rockers (20, 22) such that, during tilting of the linkage when climbing an obstacle (24), a load applied to one roller wheel (11) transfers to both other rollers (12, 13) through the connection (23) to increase the pressure uniformity of the track on the ground.
A tractor (10) has a secondary brake apparatus (18) actuated by a flexible cable apparatus (22) through an operator controlled lever (36). The flexible cable apparatus (22) has a U-shaped bracket (48) connected between the tractor frame (12) and an end of the flexible cable housing (24) adjacent the hand lever (36). A load cell (64) mounted between the other leg (54) of the U-shaped bracket (48) and the frame (12) indicates the load between the leg (54) and the frame (12). The U-shaped bracket (48) has a given stiffness so that the load applied to the load cell (64) is less than the reaction load of the cable housing (24).
