A vibration-absorbing track driving method with adjustable ground clearance

Abstract

A vibration-absorbing track driving method with adjustable ground clearance includes that the vibration damping track drive device with adjustablevibration-absorbing track driving method with adjustable ground clearance is used for vibration damping height adjustment, one end of the upper frame assembly of the track driving device is provided with a driving wheel, At that other end of the upper frame assembly is provide a track adjuster for connection with the rear support wheel assembly, A load-bearing wheel assembly is arrange on a lower platform frame assembly; a shock absorb, a hydraulic cylinder assembly and a platform frame support frame assembly are respectively arranged between that upper platform frame assembly and the lower platform frame assembly; and a track is sleeved on a driving wheel, a rear support wheel assembly and a load-bearing wheel assembly; During the lifting and lowering process of the track driving device, the track driving height changes and the surrounding perimeter remains unchanged, which can effectively prevent the track from falling off; At that same time, the hydraulic cylinder is adopt for lifting and lower the upper platform frame and the lower platform frame, the relative moving element are few, and the track height adjustment is simple; The hydraulic cylinder spring is installed between the hydraulic cylinder and the lower frame, and adjustsany height in the range of lifting and lowering to have the function of damping vibration.

Description

technical field [0001] The invention relates to the technical field of crawler belt drive, in particular to a vibration-absorbing crawler belt drive method with adjustable height from the ground. Background technique [0002] Tracked vehicles have a large grounding area and low grounding specific pressure, and can work in relatively harsh environments. However, the ground clearance and center of gravity height of tracked vehicles have a great impact on their passability and safety. The ground clearance is low, and the passage of tracked vehicles If the performance is poor, the advantages of tracked vehicles cannot be fully utilized; if the ground clearance is large, the center of gravity of tracked vehicles will be high, and rollover will easily occur when driving on slopes or turning quickly, which will affect driving safety. At the same time, due to the complex structure of the crawler driving system, the tracked vehicle mainly adopts the direct drive shaft transmission mo...

[0002] Tracked vehicles have a large grounding area and low grounding specific pressure, and can work in relatively harsh environments. However, the ground clearance and center of gravity height of tracked vehicles have a great impact on their passability and safety. The ground clearance is low, and the passage of tracked vehicles The performance of tracked vehicles is poor, and the advantages of tracked vehicles cannot be fully utilized; if the ground clearance is large, the center of gravity of tracked vehicles is likely to be high, and rollover is prone to occur when driving on slopes or turning quickly, which will affect driving safety.

At the same time, due to the complex structure of the crawler driving system, the tracked vehicle mainly adopts the direct drive shaft transmission mode, and the track and the tracked vehicle are not directly provided with a suspension, which makes it difficult to adjust the height of the tracked vehicle. The mass of the system is very large. After setting the suspension, the unsprung mass is high, which leads to poor transmission effect. However, if elastic or semi-rigid elastic devices are installed inside the tracked driving system, it is also difficult to achieve height adjustment.

For tracked vehicles equipped with elastic suspensions, although the ride comfort is improved by setting elastic elements, the reliability is better on engineering machinery or armored vehicles with heavy vehicle weight and metal tracks, but the vehicle weight On a farmland operation vehicle that is light and uses rubber tracks, the tracked driving system with elastic elements can easily lead to track slipping failures
