At present driver for vehicle is general rough is divided into two classes: wheeled and crawler type.Come relatively from performance, the grade climbing performance of crawler belt, off-road capability, current performance (to geostatic pressure) is far superior to wheeled car, but wheeled car running at high speed on highway also is higher than continuously tracked vehicle far away, moreover the manufacturing of wheeled car and maintenance cost also are lower than continuously tracked vehicle, but wheeled car especially troop operation vehicle traffic potential under some environment just is lower than continuously tracked vehicle, typical example is substantially helpless with wheeled car at rugged muddy uneven rural atmosphere, your wheel many in muddy sleety weather environment equally strong can't putting to good use, and substantially as though walking upon flat ground with crawler belt.

Cut both ways, segment, from maneuverability, the universal type optimal in structure that the most suitable the sort of requirement of continuously tracked vehicle can both be used in any occasion that comprises under the exceedingly odious landform, this is that this is so that the VCI of continuously tracked vehicle is lower because the continuously tracked vehicle sky is born with greatlyr than wheeled car area of contact over the ground.Recently in an evidence of Bosnia wheeled car in maneuverability and the protection innately a little less than.And the test of carrying out for highway shows, wheeled car has higher maneuvering performance and speed at highway; But in the time of the test cross country power, the deficiency of wheeled car has just thoroughly come out in the time of wet soil or accumulated snow environment.

Simultaneously, the cost of continuously tracked vehicle is higher than wheeled car far away, and the crawler belt wearing and tearing also are that sizable crawler belt is in case fracture has just lost the operational performance of car load, the several wheels of many group wheeled cars have been broken also and can also have been moved a segment distance, moreover the cost of wheeled car also is lower than continuously tracked vehicle, but substantially must use crawler belt as heavy armored fighting vehicle, not so can be because of overweight, excessive and almost do not have open-air traffic potential to geostatic pressure.

So, having does not have a kind of way can be so that the good maneuvering performance of the existing wheel car of engineering truck, can have again crawler vehicle open-air adaptive capacity which? yes, although at present continuously tracked vehicle is adopting some novel crawler belts (crawler belt of doing such as rubber, China Patent No. 200520040546.6) noise significantly decreases and behind the road of the absorbing wheel, but still is higher than by contrast wheeled car far away.But this kind crawler belt is rubber, its intensity a little less than, can't use especially in the situation that run into firebomb.

Summary of the invention

In order to solve the deficiencies in the prior art, the invention provides a kind of telescopic crawler belt, this crawler belt has flexible ability, can satisfy the needs of all wheeled car repackings, and do not change the wheeled car steering hardware directly install additional the crawler travel vehicle, especially be fit to army existing 8 * 8,6 * 6 armored vehicles such as grade, and the installing additional of Wheel Engineering, key thinks about and does not hinder the operation of crawler belt top to get final product, and changes the slit between the crawler belt two edges when turning owing to being reserved with of caterpillar block, and nothing overlap joint between two caterpillar blocks, therefore noise is extremely low, is a kind of flexible pedrail truly.

The technical solution adopted for the present invention to solve the technical problems is: a kind of telescopic crawler belt, the caterpillar block that comprises sheet, it is characterized in that, the Flexible Connector that also comprises V-arrangement, two ends at described Flexible Connector are provided with trepanning, be fixed with respectively a pair of connecting pin at the caterpillar block two ends, described Flexible Connector links into an integrated entity two adjacent caterpillar blocks rear by trepanning and cooperating of connecting pin and has fastener fastening, and some caterpillar blocks join end to end and form the crawler belt of a sealing.

Also comprise a positioning plate, and be provided with the strip hole corresponding with Flexible Connector two trepannings at described positioning plate and prevent that crawler belt is subject to powerful external force and destroys the elastic limit of V-arrangement elastic component, described positioning plate is installed between Flexible Connector and the caterpillar block.

Described positioning plate is drift angle triangle down.

Be respectively equipped with one to the triangle flange of lower hem in described caterpillar block both sides.

In the described trepanning and connecting pin cooperation place increases by a tilting bearing.

Respectively that described connecting pin is located in the pin-and-hole by a pin-and-hole at described caterpillar block two ends.

The invention has the beneficial effects as follows: the Flexible Connector among the present invention has preferably elasticity, so that whole crawler belt has higher telescopicing performance, this is the not available characteristic of common crawler belt.Cooperate in addition positioning plate, can so that telescopicing performance is limited, prevent that the Flexible Connector distortion is excessive.Have the following advantages: the steering hardware that does not change existing wheeled car, employing is directly applied mechanically on existing wheel car wheel and is got final product, and the present invention can be inserted in and severally be taken turns interior use and also can be inserted in single-wheel or the two-wheel (crawler belt widen especially city bus and transport vehicle at the safe anti-slipping chain of ice and snow weather) and use.In addition, for Wheel Engineering, although strong at smooth highway capacity, but the traffic potential in the abominable building ground of rugged and rough environment is just weaker, if have a flexible steel crawler belt to be sleeved on fast on the wheeled car this moment, its work efficiency will strengthen greatly, can simply reequip existing compartment, uses as a kind of simple annex.
