Double-row compound bearing wheel set crawler-type moving chassis damping traveling mechanism

Abstract

The invention relates to a double-row compound bearing wheel set crawler-type moving chassis damping traveling mechanism which comprises a driving wheel set, a driven wheel set, a guide wheel set, double-row compound bearing wheel sets, a fixing hanger and a crawler belt, wherein the driving wheel set is connected with a main motor through a driving wheel shaft; the driven wheel set is connected with the fixing hanger through a driven hanging beam shaft; the guide wheel set is connected with the fixing hanger through a guiding hanging beam shaft; the bottom of the fixing hanger is connected with the double-row compound bearing wheel sets through damping swinging arm plates; elastic components are connected between the fixing hanger and the damping swinging arm plates; six double-row compound bearing wheel sets are arranged; three double-row compound bearing wheel sets are respectively arranged on each side of the damping traveling mechanism. The double-row compound bearing wheel set crawler-type moving chassis damping traveling mechanism has the advantages of direct power output, strong maneuverability, simple structure, convenience in maintenance, high reliability, high universality and wide application scope. When the damping traveling mechanism encounters with barriers, the mechanism can realize the topographical adaptive function through the deflection of the double-row compound bearing wheel sets; the safety of the device is protected; the stable obstacle-surmounting property is realized.

Description

Technical field [0001] The invention relates to a double-row composite load-bearing wheel set crawler type mobile chassis damping walking mechanism. Background technique [0002] The crawler-type mobile chassis has the advantages of flexible action, large contact area with the ground, and strong ability to traverse obstacles. However, when the road condition is not good or the obstacle needs to be traversed, for example, when the crawler-type chassis passes through the road with protrusions, The crawler will be impacted by the outside, which will cause the chassis to vibrate, which directly affects the smooth operation and reliable operation of the equipment installed on the chassis, and sometimes even damages the internal electrical components of the equipment, causing the equipment to malfunction, and even cause accidents such as equipment fire and explosion. Therefore, the crawler-type mobile chassis, as the walking mechanism of related machinery, has always been developed aro...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the ordinary crawler-type mobile chassis only has a single suspension system or a shock-absorbing structure, and its shock-absorbing effect is limited, and it is difficult to provide better protection for the crawler-type mobile chassis and its additional equipment; while the shock-absorbing effect is better The structure of the shock absorption system is relatively complex, not only has high requirements for machining and assembly technology, but also has high requirements for control due to the addition of various dampers and sensors, inconvenient maintenance, high cost, and poor practicability

In addition, almost all load-bearing wheels in China currently use a single-row longitudinal structure. Since only the middle row of rims of the load-bearing wheels is in contact with the belt, the area of ​​friction between the single-row longitudinal type of load-bearing wheels and the track structure is small, which is likely to cause instability.

When the mobile chassis passes through uneven and sharp obstacles or edge surfaces, due to the limitation of the single-row longitudinal structure of the load-bearing wheels, the track is very prone to sideways phenomenon, which may damage the load-bearing wheels and track mechanism, and cause the mobile chassis to Rollover occurs, causing greater losses
