Abstract
The utility model discloses a gathering-arm tracked chassis and a vehicle. A gathering-arm crossing obstacle device assembly is hinged with the front end of the track assembly of the chassis; and a folding oil cylinder is connected between the gathering-arm crossing obstacle device assembly and the track assembly. When in off-road driving, the vehicle runs by adopting caterpillar drive on common ground; and the gathering-arm crossing obstacle device stretches forwards when the vehicle climbs up a steep stair-type obstacle, meanwhile, the chassis and the vehicle realize boosting obstacle cross function mutually under the driving of the track assembly, or the vehicle runs back and levels the obstacle in advancing direction backwards so as to create a condition for smooth running of the vehicle. The utility model is suitable for various tracked vehicles such as an agricultural tracked tractor, a tracked excavator, a tracked military vehicle, a tracked felling machine, a tracked dozer, a tracked forklift and the like.
Description
Technical field
The utility model relates to a kind of cross-country chassis, relates in particular to a kind of jaw crawler type chassis and vehicle.
Background technology
Caterpillar chassis 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, caterpillar chassis 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.
The utility model content
The purpose of this utility model provides a kind of jaw crawler type chassis and vehicle that can pass through rapid stepped appearance obstacle in land locomotion.
The purpose of this utility model is achieved through the following technical solutions:
Jaw crawler type of the present utility model chassis comprises track rail assembly, and the front end of described track rail assembly is hinged with jaw obstacle detouring device assembly.
Jaw crawler type vehicle of the present utility model comprises car body, and described car body is provided with above-mentioned jaw crawler type chassis, 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.
The technical scheme that is provided by above-mentioned the utility model as can be seen, jaw crawler type described in the utility model chassis 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 of the present utility model chassis, 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 and described track idler 5 are hinged.
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 the chassis 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 chassis 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 vehicle of the present utility model, its preferable specific embodiment comprises car body as shown in Figure 4, and car body is provided with above-mentioned jaw crawler type chassis, and 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 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 utility model 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 utility model 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; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
