Problems solved by technology

[0005] So, is there a way to make engineering vehicles not only have the good maneuverability of wheeled vehicles, but also have the field adaptability of tracked vehicles? Yes, although the noise of tracked vehicles has been significantly reduced after adopting some new types of tracks (such as rubber tracks, China Patent No. 200520040546.6) and vibration-absorbing road wheels, it is still much higher than that of wheeled vehicles. vehicle
However, this kind of track is a rubber product, its strength is weak, and it cannot be used in the case of incendiary bombs

Embodiment 1

[0023] Such as Figure 1 to Figure 6 As shown, a telescopic crawler track includes a sheet-shaped track shoe 1, which is a rolled steel piece (casting, forging, stamping processing malleable steel, spring steel, and welding processing, etc.), and can be provided with anti-skid on the surface. The pattern forms two protrusions 11 on the outer surface of the track shoe 1, which can improve the strength and also increase the gripping force with the ground. Two pin holes 12 (long through holes) are preset in the lateral direction of the track shoe, and a circular connecting pin 2 is respectively inserted into the pin holes 12. The connecting pin is a connecting piece, using high-strength pins, and locking or welding On the track shoes, form one piece.

[0024] Also includes a V-shaped elastic connector 3, the V-shaped elastic connector is a forging, has a good modulus of elasticity, and the two ends of the elastic connector 3 are provided with sleeve holes 31, and self-aligning b...

Embodiment 2

[0028] Such as Figure 7 As shown, the difference from the first embodiment is that the shape of the limiting plate 4 has been changed, and it is a rectangular plate instead of a triangular shape with the apex pointing down. By turning down on both sides of the track shoe 1 to form a downwardly folded triangular flange 13, it can also function as a tire rib to prevent the track from falling off from the tire.

Abstract

A telescopic track belongs to an engineering track and comprises plate-shaped track plates. The telescopic track is characterized by comprising V-shaped elastic connecting pieces. Sleeve holes are arranged at two ends of the elastic connecting pieces, a pair of connecting pins is respectively fixed at two ends of the track plates, the elastic connecting pieces are matched with the connecting pins through the sleeve holes to connect two adjacent track plates integrally, every two adjacent track plates are fastened through a fastening piece respectively, and a plurality of track plates are connected in end-to-end mode to form a closed track. The elastic connecting pieces have good elasticity, the whole track has high telescopic performance, and a common track does not have the characteristic. In addition, limit plates are matched, the telescopic performance can be restrained, and the elastic connecting pieces are prevented from being deformed too much.

Description

technical field [0001] The invention relates to a crawler belt, in particular to a telescopic crawler belt. Background technique [0002] At present, vehicle drive systems are generally roughly divided into two categories: wheeled and tracked. In terms of performance, the crawler's climbing performance, off-road performance, and traffic performance (ground pressure) are far superior to wheeled vehicles, but the high-speed driving of wheeled vehicles on the road is also much higher than that of tracked vehicles. The manufacturing and maintenance costs of vehicles are also lower than tracked vehicles, but wheeled vehicles, especially troop combat vehicles, have lower traffic capacity than tracked vehicles in some environments. A typical example is that wheeled vehicles are basically powerless in rough and muddy wild environments , Your wheels are as powerful as they are in muddy, rainy and snowy weather, but you can't use them with crawlers. [0003] Each has its own advanta...
