Description

Technical Field

[0001] The invention relates to the technical field of tracked vehicles, in particular to a tensioning device for tracked vehicles, belonging to the technical field of tensioning devices. Background Art

[0002] A crawler vehicle refers to a "car" that uses a crawler running system instead of a wheel running system. This type of vehicle has low unit pressure on the ground, small sinking, strong adhesion, and strong driving ability. The cab, cargo platform or carriage are basically the same as ordinary wheeled vehicles. Generally, according to the structure of the running system, it can be divided into three types: semi-track type with sleds or wheels on the front axle (driven axle) and tracks on the rear axle, full-track type with tracks on both the front and rear axles, and wheel-track type with interchangeable wheels and tracks. The track is a flexible chain ring driven by the driving wheel and surrounding the driving wheel, road wheel, inducer wheel and support wheel. The track consists of track shoes and track pins. The track pins connect the track shoes to form a track chain. There are holes at both ends of the track shoe, which mesh with the driving wheel. There is an induction tooth in the middle, which is used to straighten the track and prevent the track from falling off when the tank turns or tilts. There are reinforced anti-skid ribs (referred to as patterns) on the side that contacts the ground to improve the firmness of the track shoe and the adhesion of the track to the ground.

[0003] After searching, the patent announcement number CN108674504A discloses a modular track device for a vehicle. The utility model discloses a modular track device for a vehicle, which relates to a track device. The invention discloses a modular track device for a vehicle and a vehicle. The modular track device includes a bracket, a driving wheel assembly, a supporting roller assembly, a tensioning wheel assembly and a track. The driving wheel assembly is installed on the bracket, including a driving wheel for driving the track device to walk; the supporting roller assembly is installed on the bottom of the bracket, including a supporting roller for supporting the track device; the tensioning wheel assembly is installed on the bracket, including a tensioning wheel for tensioning the track device; the track is sleeved on the driving wheel, the supporting roller and the tensioning wheel. The vehicle using the track device has the advantages of strong driving ability and good adaptability to complex terrain.

[0004] The defects of an existing tensioning device for tracked vehicles are as follows: during the use of an existing tensioning device for tracked vehicles, when the tracked vehicle is traveling on diverse terrains and changing load conditions, the tension of the track is crucial to ensuring the stability and driving efficiency of the vehicle. Proper adjustment of the tension can prevent the track from slipping on soft ground, reduce the wear of the track on hard ground, and avoid derailment of the track when traveling at high speed. Many existing tensioning devices require manual adjustment, which is not only time-consuming, but also may be difficult to accurately control the tension in some cases. In complex terrain or emergency situations, this adjustment method may not be flexible or timely. Complex structure: Existing tensioning devices may have complex structures, including multiple components and connection points, which not only increases manufacturing and maintenance costs, but may also affect the performance of the entire system due to component failure or wear. At the same time, during off-road driving, tracked vehicles often encounter bumps and impacts, which is mainly caused by the uneven terrain. When there are bumps or depressions on the ground, the tracked vehicle will be subjected to impact force from the ground during driving. This impact force will be directly transmitted to the vehicle body, causing the vehicle body to vibrate, which not only affects the vehicle's driving stability and ride comfort, but may also cause damage to the vehicle's key components, thereby reducing vehicle performance. For this reason, we propose a tensioning device for tracked vehicles to solve the existing problems. Summary of the invention

The pushing rod 307 can be pushed by the linkage rod 303, so that the connecting block 309 installed on one side of the pushing rod 307 can slide along the inside of the vehicle body 1, so that the tensioning wheel 3 installed on one side of the mounting plate 301 can be squeezed with the inner side of the crawler body 102, so that the crawler body 102 can be conveniently tensioned during the covering process. At the same time, the limiting groove 311 can make the pushing rod 307 more stable during the movement, so that the installation The stabilizing effect is increased during the pushing process of the mounting plate 301. When the walking wheel 202 is traveling on a bumpy road in the wild, the walking wheel 202 is squeezed up and down, so that the connecting plate 201 installed on the inner side of the walking wheel 202 can rotate around the first mounting axis 2.
