Abstract
PURPOSE: To ensure a small size device and to improve reliability, by mounting feeding portions for supplying pressure medium to the idler side and the spring side.
CONSTITUTION: Left and ritht idlers 1, 1' of a crawler type car and a spring 19 for absorbing and damiping overload when overload is applied to an endless track are connected by means of passages 7, 9 of feeding pressure medium while floating pistons 13, 13' for limiting moving range are mounted betwen the idler 1 and the spring 19, said pressure medium feed passages 7, 9 are divided into the idler 1 aide and the spring 19 side, and pressure medium feed portions for supplying pressure medium are installed to each side. Above-mentioned arrangement results in one spring 19 mechanism, independently ensures maxium stroke in the left and ritht sides, allows a structure that does not reduce maximum load, eliminates the need for left and right same initial tension, allows restoration to set load even after working, and improves reliability without increaing the pressure of a piping not less than a fixed value
