Example Embodiment

[0028] The present invention will be described below in conjunction with specific embodiments:

[0029] Reference attached figure 1 , The swing arm type double-section wheel-track composite special engineering vehicle chassis in this embodiment includes a frame 1, a main bridge assembly, a half-bridge assembly and an outrigger assembly. The overall structure is symmetrical from front to back and from left to right.

[0030] The main axle assembly includes a main axle 3, main wheels 12 and a main axle steering cylinder 10. The main axle is divided into two front and rear main axles, and the front and rear main axles are symmetrically fixed at the bottom of the frame; the two ends of the main axle are respectively connected to the main wheels by their respective rotating brackets 8, and each main wheel is connected by its own hydraulic motor 9 independent drive. The end of the main axle steering cylinder is hinged to the middle of the main axle, and the output end of the main axle ...

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...
