Description

Casual track structure for individual tanks

technical field

The utility model relates to the technical field of personal crawler vehicles, in particular to a casually mounted crawler structure for individual tank vehicles.

Background technique

Personal tracked vehicles allow their users, and in some cases passengers, to travel over rough (and in many cases unmodified) terrain. The most well-known example of a personal tracked vehicle is the snowmobile. Other types include all-terrain vehicles and vertical personal tracked vehicles equipped with (usually four) tracks instead of wheels, most conventional personal tracked vehicles include a suspension system (or suspensions) associated with their track or tracks system). The suspension system is designed to absorb at least some of the shocks generated by the vehicle traveling over uneven surfaces in the terrain. As the vehicle travels over terrain, uneven road surfaces create displacement and deflection of its suspension system.

Given the length of time snowmobiles have existed, the most advanced suspension systems in these types of vehicles are likely to be found on snowmobiles. In a snowmobile, the rear suspension supports (in all mass-produced vehicles) the single looped track used to propel the vehicle. An endless track is tensioned and encircles a pair of parallel sliding tracks a plurality of idlers and at least one drive wheel or sprocket. A shock-absorbing mechanism, including compression springs, hydraulic dampers, and/or other shock-absorbing elements, pushes the snowmobile's sliding tracks and chassis (also known as the frame) apart at rest against the weight supported on the suspension system. Snowmobile suspension systems are typically four-bar linkages. These are only general characteristics of modern snowmobile rear suspension systems. Those skilled in the art know that there are many detailed differences between the various conventional snowmobile rear suspension systems.

Due to differences in their construction, other types of personal tracked vehicles do not use the same type of suspension system as snowmobiles to support their tracks. Snowmobile rear suspension systems are not directly applicable to these vehicles. Conventional kits for converting a standard 4 wheel ATV into a 4 track vehicle (with each track replacing a wheel) typically use the suspension already on the ATV (with the wheels) alone, but in some cases add components to the such a system. In any case, they are different from snowmobile track suspension systems.

Unlike vertical personal tracked vehicles. Vertical personal tracked vehicles are the latest addition to this class of vehicles. In such a vehicle, there are no seats. There is only a platform on which the driver stands when using the vehicle. A pair of tracks (one on each side of the vehicle, under the platform) propels the vehicle. The engine is arranged laterally between the tracks below the platform. Users initiate vehicle steering by shifting their weight to the right or left, which causes one track to drive faster than the other. Vertical tracked vehicles are lighter, smaller and more compact than snowmobiles and ATVs. For reasons including these, suspension systems similar to those used in snowmobiles or ATVs are not suitable for such vehicles.

In addition, due to the complex structure of the existing crawler-type traveling mechanism, it is troublesome to install and disassemble the crawler, which greatly increases the difficulty of assembling the crawler-type traveling mechanism and the maintenance cost of the later equipment.

In this embodiment, the plurality of anti-off positioning blocks 6 are in two rows, and there is an interval between the two rows of anti-off positioning blocks 6, and the two front support wheels 5 ride on each row of anti-off positioning blocks 6 respectively. outside. Due to the setting of the anti-off positioning block 6, the individual tank vehicle can effectively prevent the track 1 from detaching from the front support wheel 5 during the walking process, and the operation of the individual tank vehicle is more stable and practical, even in the environment of more severe road conditions. Guarantee the normal use of individual tank vehicles.

In this embodiment, the load-bearing wheel set includes a short rocker 7, a main beam 8 arranged on the vehicle body, and a long rocker 9 hinged to the middle of the main beam 8, and the hinge between the main beam 8 and the long rocker 9 is connected to the short The upper end of the rocking arm 7 is movably connected, and a first shock absorber 10 is connected between the upper end of the long rocking arm 9 and the lower end of the short rocking arm 7 . Specifically, the lower end of the long rocker arm 9 and the lower end of the short rocker arm 7 are hinged with load-carrying wheel frames 11 , and both ends of the load-carrying wheel frame 11 are equipped with middle load-bearing wheels 12 .
