Abstract
The utility mode discloses a foldable crawler-type chassis and a vehicle. A main crawler assemble of the chassis is hinged with a secondary crawler assemble; and a foldable oil tank is connected between the main crawler assemble and the secondary crawler assemble. When a vehicle is driven in travel cross-country, a main crawler is used for driving on ordinary ground; when the vehicle climbs over cliffy steps and obstruction, the vehicle is driven by the combined drive of the main crawler and secondary crawlers and passes over the obstruction through the stretching movement of two crawlers. The foldable crawler-type chassis is applicable to various crawler-type vehicles such as an agricultural crawler tractor, a crawler excavator, a crawler-type military vehicle, a crawler-type harvesting machine, a crawler bulldozer, a crawler-type fork lift truck and the like.
Description
Technical field
The utility model relates to a kind of cross-country chassis, relates in particular to a kind of foldable 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: main track motor 1, main Athey wheel side reducer 2, main track sprocket 3, main crawler belt 4, main 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 foldable 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:
Foldable crawler type of the present utility model chassis comprises main track rail assembly, and the front end of described main track rail assembly is hinged with secondary track rail assembly.
Foldable crawler type vehicle of the present utility model comprises car body, and described car body is provided with above-mentioned foldable crawler type chassis, and described car body is connected with described main track rail assembly, and the front end of described main track rail assembly is hinged with described secondary track rail assembly.
The technical scheme that is provided by above-mentioned the utility model as can be seen, foldable crawler type described in the utility model chassis and vehicle, because the front end of main track rail assembly is hinged with secondary track rail assembly, in land locomotion, when running into rapid stepped appearance obstacle, can adopt major and minor crawler belt to unite to drive and pass through obstacle by two crawler belt stretching routines.

The specific embodiment
Foldable crawler type of the present utility model chassis, its preferable specific embodiment comprises main track rail assembly as shown in Figure 3, the front end of main track rail assembly is hinged with secondary track rail assembly.
The front end of main track rail assembly is provided with main track idler 5, and the rear end is provided with main track sprocket 3, is connected with main crawler belt 4 between main track idler 5 and the main track sprocket 3;
The front end of secondary track rail assembly is provided with secondary track idler 6, and the rear end is provided with secondary track sprocket 9, is connected with secondary crawler belt 7 between secondary track idler 6 and the secondary track sprocket 9;
Also can be hinged between main track rail assembly and the secondary track rail assembly by other position, it is first-class that secondary track rail assembly also can be articulated in the main body on chassis.
Secondary track rail assembly can be connected with folding actuating device, is used to drive secondary track rail assembly and rotates relative to main track rail assembly, changes the angle between the two.
Concrete folding actuating device can be folding oil cylinder, and an end of folding oil cylinder can be hinged with main track rail assembly, also can be hinged with other position of actuating device; The other end and secondary track rail assembly are hinged.Also can select other folding actuating device for use, as electronic, pneumatic, mechanical drive etc.
Above-mentioned main track sprocket 3 is connected with main caterpillar drive.Main caterpillar drive comprises main track motor 1, main Athey wheel side reducer 2 etc.
Foldable 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 foldable crawler type chassis, and car body is connected with main track rail assembly 11, and the front end of main track rail assembly 11 is hinged with secondary track rail assembly 12.Can be connected with folding oil cylinder 13 or other folding actuating device between main track rail assembly 11 and the secondary track rail assembly 12.
Described foldable 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 change present continuously tracked vehicle can only and to the basic structure that two crawler belts are installed, make crawler body realize vertically arranging double track propulsion, improve vehicle single-piece carrying capacity.Can realize folding mutually special construction by double crawler belt, solve the problem that single crawler belt is obstructed by the ladder landform.
By the mode of travelling of major and minor track propulsion, can also can drive simultaneously by main crawler belt independent drive, to adapt to the needs that travel of different terrain by major and minor crawler belt.Adopt main track propulsion to travel on general ground, when climbing up and over precipitous ladder obstacle, adopt major and minor crawler belt to unite to drive and pass through obstacle by two crawler belt stretching routines.
The principle that vehicle of the present utility model is crossed the stepped appearance obstacle is:
As shown in Figure 4, when running into precipitous stepped appearance obstacle, at first secondary track rail assembly 12 is turned up, made vehicle near obstacle;
As shown in Figure 5, handle folding oil cylinder 13 then secondary track rail assembly 12 is stretched, at this moment, main track rail assembly 11 will under the driving of major and minor crawler belt, will be passed through obstacle by perk smoothly with the front portion of car body.
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.
