Problems solved by technology
In the process of slipping and subsidence, the increase of subsidence will increase the bulldozing area at the same time, and the vertical component of the rolling action on the bulldozing area during the rolling process of the wheel is just the direction of the strongest bearing capacity of sand, so the increase of subsidence will increase the rolling resistance. Significantly increased, may cause slippage or even make it impossible to travel
[0004] In order to make conventional wheeled vehicles run normally on soft sandy ground, measures such as special desert tires and increasing the number of axles are often used to reduce the ground contact pressure between the wheel and the sandy ground contact surface, and reduce wheel slippage and subsidence. However, the tire structure is too large. , complex chassis structure and other issues

The invention discloses a track shoe suitable for vehicles running on sand, and belongs to the mechanical field of agriculture and forestry, military use, special environment operation and the like. The invention discloses a track shoe suitable for a vehicle running on sand. The track shoe comprises a middle base plate and (left and right) wing plates connected to the middle base plate. The middle base plate is provided with meshing holes, induction teeth, raceway surfaces, outer convex pin lugs and grooves, and transmission of power from a driving wheel to a track shoe is mainly completed; transverse thorns, inclined thorns, reinforcing ribs and sand discharging holes are arranged on the wing plates, transmission of power from the track shoe to the ground is mainly completed, and therefore the whole vehicle has enough driving force. The track shoe has the advantages of being simple in manufacturing process, stable in work and the like, and can solve the problems that a conventional vehicle is extremely prone to slipping and sinking when running on soft sand and even cannot run.
Description
technical field [0001] The application relates to machinery fields such as agriculture and forestry, military use, special environment operation, etc., and particularly relates to a track shoe suitable for vehicles traveling on sandy ground. Background technique [0002] The crawler walking mechanism is generally composed of track shoes, driving wheels, supporting wheels, supporting sprockets, guide wheels and tensioning mechanisms. It is a supporting part of a large mechanical whole machine, used to support the weight of the whole machine, bear the force generated by the mechanism during the operation, and complete the advancement, retreat, turning and operation movement of the whole machine. Among them, the track shoe is a key part of the vehicle in contact with the ground, and its structure directly affects the dynamic performance of the vehicle. [0003] Conventional wheeled vehicles are very prone to slipping and sinking on soft sand, or even unable to move. The mecha...
