Problems solved by technology

However, its research is limited to the lifting of the car when it sinks into a depression. It cannot pass through some deep pits with a large span and obstacles with a high height. It has little effect on improving the car's ability to overcome obstacles in special occasions.

Embodiment Construction

[0015] 1 Overcome a vertically taller obstacle

[0016] Such as Figure 5 As shown, when the vehicle encounters a vertical obstacle such as a higher step during driving, first, put down the legs on the middle beam (16) and the rear beam (17), and put the sliding sleeve on the hinge of the folding link , stabilize the bridge body. Then extend the outriggers, lift the body to the height that the wheels can step on the steps, and the winch drives the body to slide out of the bridge body, step on the steps, and finally retract the bridge body.

[0017] 2 Overcoming non-vertical raised obstacles

[0018] Such as Figure 6 Shown, when vehicle has run into higher non-vertical obstacle, at first, put down the supporting leg on the middle crossbeam (16) and rear crossbeam (17), slide sleeve is enclosed within the hinge of folding connecting rod, stable bridge body. Then the supporting legs are extended, the vehicle body is lifted to the height that the wheels can step on the obstac...

Abstract

The present invention provides a vehicle obstacle crossing device by automatically bridging, which enables the vehicles to climb up the relatively higher obstacles like steps or to cross over the relatively broader deep pits. The bridge is installed under the chassis, and the body of the vehicle can slide forward and backward relative to the bridge which is characterized by a telescopic body and retractable and lifting support legs. With the help of the device in the present invention, the vehicles can cross over complicated terrains with obstacles of different heights and ditches of different spans. When traveling along the flat and straight roads, the bridge retracts under the chassis, which will not influence the normal running of the vehicles.

Description

technical field [0001] The invention relates to a transportation vehicle system, in particular to a vehicle automatic bridge over-obstacle vehicle mechanism. Background technique [0002] The M1038 vehicle of the U.S. Army is equipped with double A-arm independent suspension at the bottom of the vehicle, with a ground clearance of 410mm, a maximum climbing ability of 30 degrees, and a wading depth of 0.76m. Domestic research in this area is mainly reflected in the research of special vehicles, mostly focusing on self-loading and unloading trucks and armor protection, and there is not much research on obstacle crossing. Zuo Liping applied for the patent "Vehicle Automatic Lifting Assist Device" in 2004, and conducted some research on the improvement of the vehicle's ability to overcome obstacles. Using the vehicle's own power and hydraulic mechanism, it realized the lifting of the vehicle, making the vehicle sink into a depression. , it is easy to escape. However, its resea...
