摘要:
A spring loaded track tensioning assembly (16) for a track (14) on a track driven vehicle (10) has a spring subassembly (44) that is retained on a spring shaft (46) under a preload with a first fixed spring retainer (52) and a second slidable spring retainer (60). The spring shaft (46) has an outer end (66) that extends beyond the second spring retainer and the outer end is slidably received in a bore (38) in a piston or actuator shaft (30) of a grease cylinder (32), with the end of the shaft (30) bearing on the second spring retainer (60). The grease cylinder (32) contacts and applies a force to the second spring retainer (60), for initial positioning of the tensioning assembly (16), and additional loads on the first spring retainer (60) that compress the spring (48) cause the outer end of the spring shaft (66) to slide in the bore (38) of the actuator shaft (30) as the second spring retainer (60) slides along the spring shaft (46).
