Problems solved by technology

Wheeled amphibious vehicles have superior high-speed maneuverability on flat paved roads, but are prone to subsidence under soft ground; crawler-type amphibious vehicles have a larger grounding area, and have good obstacle-crossing and passability under complex and harsh road conditions. Due to the structural limitations of the track system itself, it is difficult to obtain a high moving speed

Embodiment Construction

[0025] Figure 1 to Figure 5 A specific embodiment of a crawler-assisted walking system of the present invention is shown, such as figure 1 As shown, it includes a crawler running gear 1, and a lifting mechanism 2 that makes the crawler running gear move vertically and pitch along the direction of travel. When the road condition is good, the crawler auxiliary walking system is retracted through the lifting mechanism, so that the mobile platform can move quickly. In the complicated road conditions at the junction of water and land, the crawler walking mechanism 1 is lowered to the ground through the lifting mechanism 2, increasing the mobility of the mobile platform. The grounding area improves the traction of the mobile platform, and solves the problem of amphibious vehicles passing through near water and tidal flats.

[0026] In this example, if figure 1 As shown, the crawler belt traveling mechanism comprises that the crawler belt 11 is sequentially connected to the suppor...

Abstract

The invention discloses a crawler auxiliary walking system which comprises a crawler walking mechanism and a lifting mechanism enabling the crawler walking mechanism to move in the vertical directionand pitch in the advancing direction. An inducer is arranged at the grounding position in the advancing direction of a crawler so that the crawler walking mechanism can form a regular trapezoidal structure with the narrow upper portion and the wide lower portion. The crawler grounding wire length and the grounding area are increased; the occupied space of a vehicle body chassis during crawler lifting is reduced; the ground gripping and traction of the crawler on the soft ground are improved; the crawler walking mechanism is retracted and released in the longitudinal direction through the lifting mechanism, the rotation of the crawler walking mechanism around a swing arm connecting point is actively controlled through a double-hydro-pneumatic-spring structure, the pitching freedom degree ofthe crawler walking mechanism in the advancing direction is increased, and the passing capacity of the crawler auxiliary system on a muddy road surface is improved. And by adopting the second-stage oil pipe with short stroke and small damping, the function similar to spring damping is achieved, and the movement stability of the vehicle crawler chassis is improved.

Description

technical field [0001] The invention belongs to the field of amphibious platforms, in particular to a crawler-assisted walking system. Background technique [0002] The amphibious platform is a means of transportation that can drive both on water and on land, and it has been widely used in the fields of freight and aquaculture; the existing amphibious platforms mainly use two driving methods: Wheeled, tracked. Wheeled amphibious vehicles have superior high-speed maneuverability on flat paved roads, but are prone to subsidence under soft ground; crawler-type amphibious vehicles have a larger grounding area, and have good obstacle-crossing and passability under complex and harsh road conditions. Due to the structural limitation of the track system itself, it is difficult to obtain a high moving speed. Contents of the invention [0003] The technical problem to be solved by the present invention is how to enable amphibious vehicles to pass at high speed on good road conditi...
