Background technology
In recent years, heavy motor vehicle has the incomparable advantage of common goods carrying vehicle, and power is big, good in economic efficiency, and demand obviously increases.Because it is economical that turning efficiency directly has influence on maneuverability, operational stability and the use of car load.Therefore the design of heavy automobile steering system is had higher requirement.The heavy motor vehicle car body is long, tonnage is big, and its steering flexibility is relatively poor relatively, and wear on tyres is serious.The utility model is simple in structure, turns to lightly, and maneuvering performance is good, and wear on tyres is little, can effectively improve the turning efficiency of automobile.
The steering swivel system of most of lorries all is a front-wheel steering, and trailing wheel is not followed and turned to, and this just causes the lorry difficulty of turning on narrow road, even can't turn.Most of lorries all adopt single bridge to turn to, the single shaft carrying reduces its weight capacity greatly, and lorry mostly adopts independent suspension, though can guarantee all wheels and ground-surface good the contact, but will make the lorry structure become complicated, can not guarantee all wheels kiss the earth simultaneously when on rough road, travelling, thereby cause the unsettled phenomenon of wheel, make the vertical load between each wheel distribute uneven.
Therefore, design a kind of maneuverability that can improve lorry, it can be turned on narrow narrow lane, thereby improve the alerting ability that turns to, can also guarantee that heavy motor vehicle travels on rough road and five lorry trailing wheel follower steering devices of the safety when turning to, be the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of maneuverability that can improve lorry, it can be turned on narrow narrow lane, thereby improve the alerting ability turn to, can also guarantee that heavy motor vehicle travels and five lorry trailing wheel follower steering devices of the safety when turning on rough road.
The technical scheme in the invention for solving the technical problem is:
Five lorry trailing wheel follower steering devices, on the axle of two propons dependent suspension primary shafies, be welded with front axle universal joint near wheel hub, before two propons, latter two steeraxle is handled by steering drag link by same hydraulic power steering device by steering gear, before, the rotation direction of back steeraxle and steering angle basic synchronization, on the semiaxis of the third axle of the two back axles of independent suspension, be welded with the back axle universal-joint, between front axle universal joint and crisscross back axle universal-joint, be connected with rigid shaft, main reduction gear, diff and semiaxis are installed on two back axles, two back axles are contained on the trammel beam, trammel beam is done hinge type with vehicle frame and is connected, the 5th is connected with vehicle frame by independent suspension separately, arrange some rubber mounts between independent suspension and the vehicle body, independent suspension and vehicle body are flexibly connected by rubber mount.
The technical scheme in the invention for solving the technical problem can also be:
Rigid shaft described in the utility model is arranged in a crossed manner two.
Steering gear described in the utility model comprises preceding adjustable straight-bar, the adjustable drag link in back, preceding steering cantilever, back steering cantilever, preceding steering cantilever is hinged by preceding steering cantilever seat and vehicle frame, back steering cantilever is hinged by back steering cantilever seat and vehicle frame, the two ends of the adjustable drag link in back are hinged with the middle part of preceding steering cantilever and back steering cantilever respectively, before an end of adjustable straight-bar and hydraulic power steering device turn to horn hinged, the other end of preceding adjustable straight-bar and the middle part of preceding steering cantilever are hinged, steering drag link and back steering drag link before described steering drag link is divided into, the end and the preceding steering drag link of preceding steering cantilever are hinged, and the end of back steering cantilever is hinged with the back steering drag link.
Two of the adjustable drag link of adjustable straight-bar and back is positive and negative screw thread socket before described in the utility model, turn-buckle and binding bolt tightly are one with the joint at adjustable drag link, shaft and two at ordinary times, unclamp two binding bolt when needing, rotate adjustable drag link shaft and can reach flexible adjustment.
Compared with prior art, the utility model has not only improved the maneuverability of lorry, and it can be turned on narrow narrow lane, thereby improves the alerting ability turn to, has guaranteed that also heavy motor vehicle travels on rough road and the safety when turning to.
