Abstract

409,225. Endless - track vehicles. POLLAK, J. E., 20, Holborn, London.- (Aktiebolaget Bofors ; Bofors, Sweden.) Oct. 27, 1933, No. 29894. [Class 79 (i).] A spring arrangement for the supporting rollers 9-12 of a track-laying vehicle in which one roller of each pair is supported through the intermediary of a strong spring by an arm carrying the other roller, is characterized by the feature that the stiff spring 17 is movably mounted relatively to the arm 16 and the fixed end of the spring is connected with the arm 16 through the intermediary of a weak spring 20 which is only intended to absorb slight shocks. In the construction shown, the roller 10 is mounted on an axle 3 between a pair of arms 16 rigidly connected together by a sleeve 15 rocking on a shaft 13 fixed to the vehicle frame 1. The axle 4 of the roller 10 is mounted in eyes of a pair of stiff springs 17 fixed at their other ends to arms 19 secured to a shaft 22 rocking in a boss 24 integral with the arms 16. The outer ends of the arms 19 bear against the weak springs 20 enclosed in housings 21 formed in the arms 16. The springs 20 are adjustable. The rocking movement of the springs 17 relatively to the arms 16 is limited by discs 26 on the springs 20 adapted to bear against the arms 16, so that while the springs 20 absorb light shocks, on heavy shocks occurring the discs 20 abut against the arms 16 and the strong springs 17 are flexed. Movement of the springs 17 in the other direction is checked by rubber blocks 27 fixed to bosses on the arms 16.
