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
The present invention relates to a kind of cross-country walk device, relate in particular to a kind of jaw crawler type walking device and vehicle.
Background technology
Cterpillar drive is mainly used on the various way less field work vehicles, as movable road, drive wheel is travelled with crawler belt at the support lower edge of caterpillar wheel crawler belt by the cranking traction vehicle; Generally be that left and right vehicle wheel respectively disposes a track rail assembly.For example: agricultural track type tractor and engineering go up tank commonly used etc. with excavating machine and military affairs, all belong to the vehicle of two track propulsions.
As shown in Figure 1, cterpillar drive of the prior art, its essential structure comprises: track motor 1, Athey wheel side reducer 2, track sprocket 3, crawler belt 4, track idler 5 etc.
There is following shortcoming at least in above-mentioned prior art:
As shown in Figure 2, in land locomotion, vehicle can only be by local landform section gently, if rapid stepped appearance obstacle appears in ground, continuously tracked vehicle power greatly also be difficult to again by.
Summary of the invention
The purpose of this invention is to provide a kind of jaw crawler type walking device and vehicle that in land locomotion, can pass through rapid stepped appearance obstacle.
The objective of the invention is to be achieved through the following technical solutions:
Jaw crawler type walking device of the present invention comprises track rail assembly, and the front end of described track rail assembly is hinged with jaw obstacle detouring device assembly.
Jaw crawler type traveling vehicle of the present invention comprises car body, and described car body is provided with above-mentioned jaw crawler type walking device, and described car body is connected with described track rail assembly, and the front end of described track rail assembly is hinged with described jaw obstacle detouring device assembly.
As seen from the above technical solution provided by the invention, jaw crawler type walking device of the present invention and vehicle, because the front end of track rail assembly is hinged with jaw obstacle detouring device assembly, in land locomotion, when running into rapid stepped appearance obstacle, can stretch forward by jaw obstacle detouring device assembly, pass through obstacle with the combined action of track rail assembly.

The specific embodiment
Jaw crawler type walking device of the present invention, its preferable specific embodiment comprises track rail assembly as shown in Figure 3, the front end of track rail assembly is hinged with jaw obstacle detouring device assembly.
The front end of track rail assembly is provided with track idler 5, and the rear end is provided with track sprocket 3, is connected with crawler belt 4 between track idler 5 and the track sprocket 3;
Jaw obstacle detouring device assembly comprises jaw 6, and jaw 6 has 2, is located at the position of both sides near track rail assembly respectively.Jaw 6 also can have one or more.
Jaw 6 is a turning shape, as square, or other shape etc.
Jaw 6 rear ends can be hinged with it by the rotating shaft of track idler 5.Jaw 6 also can be hinged with other position of track rail assembly, and the main body that also can be articulated in running gear is first-class.
Jaw obstacle detouring device assembly can be connected with folding actuating device, is used to drive jaw obstacle detouring device assembly and rotates relative to track rail assembly, changes the angle between the two.
Concrete folding actuating device can be folding oil cylinder, and an end and the track rail assembly of folding oil cylinder are hinged, or hinged with other position of running gear main body; The other end and jaw obstacle detouring device assembly are hinged.Also can select other folding actuating device for use, as electronic, pneumatic, mechanical drive etc.
Above-mentioned track sprocket 3 is connected with caterpillar drive.Caterpillar drive comprises track motor 1, Athey wheel side reducer 2 etc.
Jaw crawler type traveling vehicle of the present invention, its preferable specific embodiment comprises car body as shown in Figure 4, and car body is provided with above-mentioned jaw crawler type walking device, car body is connected with track rail assembly 11, and the front end of track rail assembly 11 is hinged with jaw obstacle detouring device assembly 12.Can be connected with folding oil cylinder 13 or other folding actuating device between track rail assembly 11 and the jaw obstacle detouring device assembly 12.
Described jaw crawler type traveling vehicle can comprise one or more vehicles in the following vehicle:
Agricultural crawler-tread tractor, traxcavator, crawler type military vehicle, crawler type harvester, crawler doer, crawler type forklift etc.The tracklaying vehicle that can also comprise other.
The present invention changes present continuously tracked vehicle can only increase jaw obstacle detouring annex by the basic structure of track propulsion on crawler body, realize that the jaw power-assisted drives, and improves vehicle single-piece carrying capacity; Change the operation scheme that present crawler body can only tangentially drive along ground, jaw arrangement is taken off in employing can make the crawler belt front end jump up vertically upward, realizes the function by the ladder obstacle, improves the problem that common crawler belt is obstructed by the ladder landform.
The principle that vehicle of the present invention is crossed the stepped appearance obstacle is:
Under the effect of folding oil cylinder 13, the track adjusting wheel center that jaw obstacle detouring device assembly 12 can track rail assembly 11 is that hinged support rotates, and meanwhile under the driving of track rail assembly 11, realizes the function of power-assisted obstacle detouring jointly; If jaw obstacle detouring device assembly 12 is after hinged support turns to the upright position forward, vehicle falls back backward, then the obstacle of working direction can be taken off backward flatly, and being that vehicle is current smoothly creates conditions.
As shown in Figure 4, when running into precipitous stepped appearance obstacle, at first jaw is ridden over top, obstacle location;
As shown in Figure 5, handling folding oil cylinder 13 then stretches jaw obstacle detouring device assembly 12 forward, the front end of track rail assembly 11 and car body is upturned, continues to pass through obstacle smoothly around hinged support revolution and track rail assembly 11 uniting under the driving to overtake at jaw obstacle detouring device assembly 12.
As shown in Figure 6, when running into obstacle simultaneously, can also adopt reversing when going up a slope, remove the obstacle of advancing with jaw after, at ahead running.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
