Abstract

764,868. Endless track vehicles. DUNLOP RUBBER CO., Ltd. July 25, 1955 [Aug. 13, 1954], No. 23512/54. Class 79(1). [Also in Group XXXII] A half-track assembly comprises a driving sprocket and below it a suspension member pivoted to the vehicle, several idler wheels mounted on the member one being spring urged against an endless track passing over the idler wheels and the driving sprocket of the vehicle, the rotation of the suspension member being positively limited. In Figs 1 and 2, the endless track embraces the driving sprocket 1 and the idler wheels 3, 4 and 5, two of which are mounted on the member 6 whose rotation about the pin 7 is limited by either cheeks 12, telescopic links 27, Fig. 6, or lateral bars engaging the member 6. The wheel 3, mounted on the bracket 8 which is slidable on the guide 9, tensions the track through the rubber or helical spring 10. The sprocket 1 comprises three discs 22, 20, 22, Fig. 3 joined at their peripheries by bars 21, the spaces between the bars allowing the dogs on the endless track to engage the sprocket.
