Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The invention can also be used as an auxiliary walking system for vehicles. The obstacle-surmounting ability of a general vehicle mainly depends on two aspects. One is the size of the wheel. The larger the diameter of the wheel, the better the obstacle-surmounting ability. The second is the adhesion between the wheel and the ground. . And as the obstacle-surmounting ability of wheel, generally not as good as the obstacle-surmounting ability of leg type mobile mechanism.

[0023] Such as Figure 1-Figure 7 As shown, the present invention provides a kind of obstacle-climbing vehicle, the wheel span of this obstacle-climbing vehicle can be extended to both sides, and each wheel...

Abstract

The invention discloses a hydraulic variant control obstacle-crossing vehicle which comprises a vehicle body and a traveling mechanism. The traveling mechanism comprises executing elements. Each executing element comprises a spoke hydraulic mechanism and a horizontal hydraulic mechanism. Each spoke hydraulic mechanism comprises a plurality of wheel track telescoping structures which are uniformly distributed on the periphery of a corresponding wheel. Each wheel track telescoping structure comprises a wheel track, a spoke and a spoke hydraulic cylinder, the wheel track is connected with one end of the spoke, the other end of the spoke is connected with the spoke hydraulic cylinder, and the spoke hydraulic cylinder controls the spoke and the wheel track to stretch and retract in the longitudinal direction. each horizontal hydraulic mechanism comprises axles and a horizontal hydraulic cylinder. Compared with the prior art, the hydraulic variant control obstacle-crossing vehicle has the beneficial effects that (1) the advantages of wheels and a leg-type moving mechanism in the aspects of speed and obstacle-crossing capacity are integrated; and (2) a hydraulic transmission system is adopted according to the characteristics that an executing mechanism is provided with a large number of hydraulic cylinders and is large in stress.

Description

technical field [0001] The invention relates to the technical field of special vehicles, in particular to a hydraulic variant control obstacle-crossing vehicle. Background technique [0002] In recent years, the frequent occurrence of natural disasters has brought huge disasters to people's production and life. However, the rescue and relief work is often greatly restricted due to the influence of equipment technology and other factors. For example, in earthquake-stricken areas, the road conditions are very bad, and many ordinary rescue vehicles cannot drive in. Therefore, in the process of emergency rescue and disaster relief, it is of great practical significance and practical value to develop an obstacle-crossing vehicle with high cross-country maneuverability. [0003] Since the 1960s when the United States and the former Soviet Union set off an upsurge in lunar exploration, scientific research institutions in various countries have successively developed various types ...
