Crawler type running device

Abstract

The invention provides a crawler type running gear, wherein the crawler spanning the driving wheel, front idler, back idler and rollers to wind is driven by driving the driving wheel using wheel rotation. A swing frame comprises a front idler supporting part for supporting the front idler and a back idler supporting part for supporting the back idler, a main frame with rollers and a swing axle mounted above the main frame; the swing frame also comprises a front connection parts for connecting the swing axle with the front idler supporting part and a back connection parts for connecting the swing axle with the back idler supporting part; and an opening formed between the front and back connection parts and the main frame and opening at the right and left direction is formed.

Description

technical field [0001] The invention relates to a tracked vehicle. Background technique [0002] Conventionally, as a crawler-type traveling device, there is a half-track-type crawler-type traveling device installed instead of wheels of a traveling vehicle such as a tractor. As the half-track-type crawler-type traveling device, there is a device configured as follows: A swing frame is supported on a frame support body fixed to a vehicle body side of a traveling vehicle so as to be swingable around a left-right direction axis, and front and rear idlers and a plurality of idlers disposed between the front and rear idlers are supported on the swing frame. The roller is provided with a driving wheel arranged on the upper side of the roller and rotatably supported on the side of the vehicle body around the axis center in the left-right direction. The crawler belt wound by the rollers circulates (refer to Japanese Patent Application Laid-Open No. 2004-148872). [0003] The swing...

Problems solved by technology

[0004] In the above-mentioned conventional crawler-type traveling device, since the swing frame has a support plate extending upward from the left-right direction inner end side of the main frame and the plate surface faces the left-right direction, and the swing shaft fixed on the support plate end side is arranged to the The main frame is welded and fixed on the left and right outer surface of the support plate with a pair of front and rear reinforcement plates, so the soil carried by the support plate and the reinforcement plate on the main frame is not easy to discharge (soil is easy to accumulate on the main frame of the swing frame) , there are problems such as that the soil accumulated on the main frame falls on the road during the movement of the driving vehicle, and its handling is laborious, and it is also laborious to remove the soil accumulated on the main frame when washing the car.
