The rear-wheel follow-up steering device disclosed by the invention has good flexibility so that the wagon can turn on a narrow road, and ensures the safety of heavy trucks running and steering on uneven roads.
Description
Technical field
The present invention relates to a kind of five lorry trailing wheel follower steering devices, especially a kind of five heavy motor vehicle trailing wheel follower steering devices.
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 property, 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 present invention 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 on narrow road, turning, even can't turn.Most of lorries all adopt single bridge to turn to; Single shaft carries its weight capacity is reduced 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, going, thereby cause the unsettled phenomenon of wheel, make the vertical load between each wheel distribute uneven.
Therefore; Design a kind of maneuverability property that can improve lorry; It can be turned on narrow narrow lane; Thereby improving the alerting ability turn to, can also guarantee that heavy motor vehicle goes and five lorry trailing wheel follower steering devices of the safety when turning on rough road, is the present technical issues that need to address.
Summary of the invention
Technical matters to be solved by this invention provides a kind of maneuverability property 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 goes and five lorry trailing wheel follower steering devices of the safety when turning on rough road.
The technical scheme that the present invention solves its technical matters is:
Five lorry trailing wheel follower steering devices; On the axle of two propons dependent suspension primary shafies near wheel hub, be welded with front axle universal joint, former and later two steeraxles of two propons are handled through steering drag link by same hydraulic power steering device through steering gear, the rotation direction of forward and backward 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, and 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 through independent suspension separately, arranges between independent suspension and the vehicle body to flexibly connect some rubber mounts independent suspension and vehicle body through rubber mount.
The technical scheme that the present invention solves its technical matters can also be:
Rigid shaft of the present invention is arranged in a crossed manner two.
Adjustable straight-bar, the adjustable drag link in back, preceding steering cantilever, back steering cantilever before steering gear of the present invention comprises; Preceding steering cantilever is hinged through preceding steering cantilever seat and vehicle frame; Back steering cantilever is hinged through back steering cantilever seat and vehicle frame; The two ends of the adjustable drag link in back are hinged with the middle part of back steering cantilever with preceding steering cantilever respectively; Before adjustable straight-bar an end 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.
Adjustable straight-bar is positive and negative screw thread socket with two of the adjustable drag link in back before of the present invention; 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 present invention has not only improved the maneuverability property 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 goes on rough road and the safety when turning to.
