Swing arm type double-wheel-track composite special engineering vehicle chassis

Abstract

The invention provides a swing arm type double-wheel-track composite special engineering vehicle chassis which comprises a vehicle frame, a main axle component, a half axle component and a support leg component. The main axle component consists of a main axle, a main wheel and a main axle steering cylinder, the half axle component consists of a half axle, a half axle wheel, a half axle steering cylinder, a swing arm, a telescopic arm and a swing arm cylinder, the support leg component comprises a support leg frame and support legs, the support leg frame is fixed onto the vehicle frame, and the support legs are symmetrically mounted on the support leg frame. By the aid of the swing arm type double-wheel-track composite special engineering vehicle chassis, a tire type traveling mode, a track type traveling mode and a wheel leg type traveling mode of a vehicle can be flexibly switched according to different road conditions, the fast moving ability of the tire type traveling mode can be played, the vehicle can be conveniently switched into the track type traveling mode according to the road conditions, a track is double-link track, adaptability to terrains is improved, the vehicle can be switched into the wheel leg type traveling mode to travel when running on oblique roads or other roads according to requirements of the terrains, and a support leg device can be switched on to carry out relevant operation when necessary.

Description

technical field [0001] The invention relates to the field of vehicle chassis, in particular to a swing-arm type double-section wheel-track composite special engineering vehicle chassis. Background technique [0002] The chassis of the vehicle is the walking device and supporting part of the whole machine. It bears the weight of the whole vehicle and the reaction force of the working device when it is working, so that the vehicle can be stably supported on the ground when it is working, and at the same time it can make the machine run in the workplace and When transferring the construction site, the running gear of the vehicle has two functions of supporting and running. At present, the running gear of the vehicle is mainly divided into two categories: crawler type and tire type according to different structures. The characteristics of the crawler walking device are that the driving force is large (usually the driving force of each crawler can reach 35%-45% of the weight of t...

AI Technical Summary

Problems solved by technology

For some vehicles that walk on complex roads or on various roads, tire-type mechanical vehicles cannot meet the driving requirements of harsh roads; crawler-type mechanical vehicles are highly adaptable to harsh ground conditions, but they are not suitable for driving on good roads such as highways. The upper movement speed is relatively slow, and the wheel-leg structure is highly adaptable to laterally inclined road surfaces, but the structure determines that it cannot bear large loads
