Abstract
The invention discloses a folding crawler type running device and a folding crawler type vehicle. The front end of a main crawler assembly of the running device is hinged with an auxiliary crawler assembly, and a folding oil cylinder is connected between the main crawler assembly and the auxiliary crawler assembly; when the running device runs on a country road, the main crawler is adopted to drive the running device to run on the general road surface; and when the running device climbs a steep ladder obstacle, the combined driving of the main crawler and the auxiliary crawler is adopted, andthe double crawlers extend to cross an obstacle. 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 folding 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: 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.
Summary of the invention
The purpose of this invention is to provide a kind of folding 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:
Folding crawler type walking device of the present invention 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 traveling vehicle of the present invention comprises car body, and described car body is provided with above-mentioned folding crawler type walking device, 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.
As seen from the above technical solution provided by the invention, folding crawler type walking device of the present invention 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
Folding crawler type walking device of the present invention, 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;
Secondary track sprocket 9 is hinged with main track idler 5, and the axis of revolution of the two can be coaxial, and hinged by this, realizes hinged between main track rail assembly and the secondary track rail assembly.
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 of running gear.
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.
Secondary track sprocket 9 can not established actuating device, passive rotation under the promotion of main track rail assembly; Also can drive by main track idler 5; Independent secondary caterpillar drive also can be arranged.Secondary caterpillar drive can comprise secondary track motor 10, secondary Athey wheel side reducer 8 etc.
Foldable 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 folding crawler type walking device, 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 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 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 invention 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.
