摘要： A track suspension means for vehicles having an endless track drive and support surface, the vehicle having frame means with forward and rear mounting points. The track suspension means which is coupled to the vehicle at the mounting points includes longitudinally disposed flexible leaf spring means normally arranged convexly to the running surface, with the leaf spring means having an axis disposed generally parallel to the track axis, and being adapted to flex vertically. The leaf spring, which carries a plurality of supporting means such as bogie wheels for the track, is secured at its forward end to the vehicle frame at the forward mounting point. The endless track suspension means includes forwardly and rearwardly disposed sprockets inscribed within the endless track, and mounting means are provided for the sprockets including axle shafts. Track propelling means are coupled to the forwardly disposed sprockets, while track tensioning means and the rear of said leaf spring are operatively coupled to the rearwardly disposed sprockets. Pivot linkage means are provided for coupling the rear sprocket mounting means to the vehicle at the rear mounting point. The pivot linkage means includes rear support shaft means journaled for pivotal rotation generally concentrically with the common axis of said rear frame mounting points, a first torque arm coupled at one end to said rear support shaft means and with a floating pivot shaft journaled to the other end of the first torque arm. A second arm is provided having one end journaled to the floating pivot, and with the other end coupled to the rear sprocket mounting means, such as the rear axle shaft. Resilient spring bias means are coupled between the frame means and the rear support shaft means and normally urge the mounting shaft means for the rearwardly disposed sprockets such as the rear axle shaft in a direction toward the lower span of the endless track.
