High-speed and heavy-duty replaceable triangular crawler wheel assembly

Abstract

The invention discloses a high-speed and heavy-duty replaceable triangular crawler wheel assembly. The high-speed and heavy-duty replaceable triangular crawler wheel assembly comprises a rubber crawler, a supporting frame, a driving wheel, guiding wheels, tensioning guiding wheels, tensioning devices and load-bearing wheels. The outer ring of the high-speed and heavy-duty replaceable triangular crawler wheel assembly is covered with the rubber crawler. The driving wheel, the guiding wheels, the tensioning guiding wheels, the tensioning devices and the load-bearing wheels are arranged on the supporting frame. The driving wheel is located at the upper portion of the rubber crawler and is connected with a chassis wheel shaft. The guiding wheels and the tensioning guiding wheels are located atthe two ends of the bottom of the rubber crawler, and the load-bearing wheels are arranged on the middle of the rubber crawler. The tensioning devices comprise oil cylinders, energy accumulators andtensioning wheel connecting frames. The oil cylinders are connected with the energy accumulators to form gas-liquid springs. The oil cylinders are connected to oil cylinder seats of the supporting frame, the lower ends of the tensioning wheel connecting frames are connected with the supporting frame to form hinge points, the tensioning guiding wheels are arranged on the middles of the tensioning wheel connecting frames, and the oil cylinders are connected with the upper ends of the tensioning wheel connecting frames. The high-speed and heavy-duty replaceable triangular crawler wheel assembly is simple and reasonable in structure, good in stability, capable of realizing fast replacement and assembling, capable of meeting the requirements of high-speed and heavy-duty, and capable of improving the ability of vehicles to deal with complex geological conditions, such as muddy and soft conditions.

Description

technical field [0001] The invention relates to a triangular crawler walking device, in particular to a high-speed and heavy-load replaceable triangular crawler wheel assembly, which belongs to the field of construction machinery and is especially suitable for emergency rescue vehicles. Background technique [0002] The tire-type emergency rescue vehicle has the characteristics of fast driving speed, good maneuverability, and simple structure, and can meet the needs of rapid transition and engineering repair operations under general road conditions. However, when it is driving and working on special roads such as gravel, ice, snow, and mud, it is prone to tire sinking, skidding, and even unstable center of gravity. Although the overall tracked equipment can well adapt to the harsh site and working environment, its installation must rely on the matching special chassis, which not only increases the weight of the vehicle, but also reduces the maneuverability of the vehicle to ...

AI Technical Summary

Problems solved by technology

Most of the heavy-duty machines use metal crawlers. Because of its unimaginable weight, it is particularly laborious to load and unload, and it seriously damages the road surface.

The overall load-bearing capacity of the existing triangular track wheels is still too small to be used in heavy machinery and large equipment. The stability of the structure itself and the anti-turning performance also need to be improved.
