Tracked and wheeled switchable traveling chassis

Abstract

The invention discloses a tracked and wheeled switchable traveling chassis. The tracked and wheeled switchable traveling chassis comprises a travelling crane frame, a power system, a control system, travelling wheel groups and two tracks, wherein the power system, the control system, the travelling wheel groups and the two tracks are mounted on the travelling crane frame; the travelling wheel groups and the tracks are respectively arranged at the two sides of the travelling crane frame, the power system is connected with the travelling wheel groups and the tracks respectively, and the control system is connected with the power system. According to the tracked and wheeled switchable traveling chassis disclosed by the invention, the quick switchover of two traveling manners, namely the travelling wheel groups and the tracks, is realized, and the shortcomings and deficiencies of the existing wheeled and tracked traveling mechanisms are overcome; the wheeled moving manner is selected when a vehicle travels on a flat road for a long distance, so that the moving speed can be increased, and the fuel consumption can be lowered; the tracked moving manner is selected when the vehicle travels on special grounds, so that the passing performance of the vehicle can be improved.

Description

technical field [0001] The invention relates to a vehicle walking chassis, in particular to a crawler and wheel-type switchable walking chassis. Background technique [0002] The crawler-type traveling mechanism has the advantages of good passability on the special ground, but it also has the disadvantages of large energy consumption and slow moving speed. The wheeled walking mechanism has the characteristics of flexible movement, fast driving speed and low energy consumption, but the trafficability of special ground is poor. [0003] Chinese patent 200410021988.6 discloses a crawler-tire hybrid drive folding car, which has the effect of crawler and tire hybrid drive, but it has higher requirements for hydraulic cylinders. First, it requires better synchronization of the upper and lower hydraulic cylinders to prevent the crawler from When lifting or lowering, the belt is loose or loose, which increases the difficulty of controlling the hydraulic cylinder. Another is that th...

[0002] The crawler-type walking mechanism has the advantages of good passability on the special ground, but it also has the disadvantages of large energy consumption and slow moving speed.

The wheeled walking mechanism has the characteristics of flexible movement, fast driving speed and low energy consumption, but the passability of special ground is poor.

[0003] Chinese patent 200410021988.6 discloses a crawler-tire hybrid drive folding car, which has the effect of crawler and tire hybrid drive, but it has higher requirements for hydraulic cylinders. First, it requires better synchronization of the upper and lower hydraulic cylinders to prevent the crawler from Loose belts or loose belts occur during lifting, which increases the difficulty of controlling the hydraulic cylinder. Another is that the hydraulic cylinder needs to be able to support the entire car, which requires more hydraulic cylinders, resulting in high cost.
