Abstract

The invention relates to an engineering machine balancing rocker arm chassis travelling device which consists of a frame, an intermediate main shaft, a rocker arm rack, a rocker arm, a set of ground gap adjusting mechanism, a travelling motor and brake device, a balance mechanism, a steering device and wheels, wherein the frame is arranged on the rocker arm rack by the intermediate main shaft andthe balance mechanism; the rocker arm rack is connected with the rocker arm by the set of ground gap adjusting mechanism; and the front end of the rocker arm is connected with the steering device which is connected with the travelling motor and brake device by a bolt and is simultaneously connected with the wheels. After the engineering machine balancing rocker arm chassis travelling device is adopted, a common chassis is guaranteed to have the functions of adjusting the posture, changing the ground gap and carrying out all-wheel hydraulic driving and hydraulic steering on the precondition that the common chassis is ensured to operate at higher movement speed, so that the obstacle climbing capability and the passing performance of a vehicle can be improved. Therefore, the engineering machine balancing rocker arm chassis travelling device has a better practical value and a wide application prospect in the technical field of engineering machinery.

Description

technical field

[0001] The invention relates to a chassis running device of construction machinery, in particular to a chassis running device of a balanced rocker arm of construction machinery. It belongs to the technical field of engineering machinery. Background technique

[0002] At present, the chassis forms applied to construction machinery mainly include crawler type, wheel-track compound type, tire type, wheel-leg type, etc. The crawler chassis has the advantages of mature structure, strong power, high grounding specific pressure, and large maximum gradeability. However, there are obvious defects such as that the maximum driving speed is small and cannot be transported on ordinary roads.

[0003] The wheel-track composite chassis solves the defects of the crawler walking mode to a certain extent, but introduces the disadvantages of too complex and heavy chassis structure, too long or too wide body size, and increased cost, which limits its application.
