Embodiment Construction

[0017] The preferred embodiment of the crawler-type walking device of the present invention is as follows: image 3 As shown, the crawler track assembly is included, and the front end of the crawler track assembly is hinged with a pawl obstacle-climbing device assembly.

[0018] The front end of the track assembly is provided with a track guide wheel 5, and the rear end is provided with a track drive wheel 3, and a track 4 is connected between the track guide wheel 5 and the track drive wheel 3;

[0019] The claw obstacle-climbing device assembly includes claws 6, and there are two claws 6, which are respectively located on both sides near the crawler belt assembly. There can also be one or more claws 6.

[0020] The claws 6 are corner-shaped, such as right-angled, or other shapes.

[0021] The claw 6 rear end can be hinged to it by the rotating shaft of the track guide wheel 5 . The pawl 6 can also be hinged with other parts of the crawler belt assembly, or can be hinged o...

Abstract

The invention discloses a gathering-arm crawler type running device and a gathering-arm crawler type vehicle. The front end of a crawler assembly of the running device is hinged with a gathering-arm obstacle crossing device assembly, and a folding oil cylinder is connected between the crawler assembly and the gathering-arm obstacle crossing device assembly; when the running device runs on a country road, crawlers are adopted to drive the running device to run on the general road surface; when the running device climbs a steep ladder obstacle, the gathering-arm obstacle crossing device extends forward; at the same time, under the driving of the crawler assembly, the function of assistant obstacle crossing is jointly realized, or the vehicle runs backward to fatten the obstacle ahead so as to create conditions for the successful passing of the vehicle. The running device and the vehicle can be applied to various crawler type vehicles, such as farming crawler type tractors, crawler type excavating machines, crawler type military vehicles, crawler type felling machines, crawler type bulldozers, crawler type fork lifts and the like.

Description

technical field [0001] The invention relates to a cross-country walking device, in particular to a crawler-type walking device and a vehicle. Background technique [0002] The crawler-type traveling device is mainly used in various field operation vehicles without roads. The crawler is used as the active road surface, so that the driving wheel drives the vehicle along the track with the support of the rollers through the track; become. For example: agricultural crawler tractors and engineering excavators, as well as tanks commonly used in the military, etc., are all dual-track driven vehicles. [0003] Such as figure 1 As shown, the basic structure of the crawler-type traveling device in the prior art includes: a crawler motor 1, a crawler wheel side reducer 2, a crawler driving wheel 3, a crawler belt 4, a crawler guide wheel 5, and the like. [0004] There are at least the following disadvantages in the above-mentioned prior art: [0005] Such as figure 2 As shown, i...
