Description
Technical field
The utility model relates to a kind of trailer, particularly relates to a kind of All-wheel Steering Device on Trailer.
Background technology
The development of current large cargo transportation device is towards the future development of modularization, combined type automobile train, in order to adapt to the demand for development of national economic development, the basis of original superimposed trailer, Combinable Full Trailer is designed and developed all kinds of super large, the large cargo that overweight, body is special transport special facilities to meet the demand of transportation market, the certainty of market and economic development; Difficulty in the transportation means of large tank class goods, domesticly currently still not to be well solved, imported large-scale equipment in some priority projects of country, much transport with the special-use vehicle of import, not only involve great expense, and there is dumb and difficulty and be applicable to the problems such as the needs of domestic existing goods and over-the-road transportation condition; Large tank class goods and equipment, in all conglomerate widespread uses such as chemical machinery, apolegamy coal, ore dressing, cement and architectural potteries, they are on the one hand from domestic, also have quite most dependence on import.The flat restriction by vehicle structure of the many employings of this type of goods transport domestic at present, transport large tank class goods has certain limitation.
At present, when domestic, superelevation, exceptional length freight overweight at overland transport, mostly selecting can assembled superduty Combinable Full Trailer, this vehicle has some superiority to Over-size transport, but also there are some shortcomings, as in order to increase tractor tyre adhesive ability, needing extra tractor truck again increases the weight of; Be connected with the draw bar between tractor truck, will the overall length etc. of car load be increased; Drawbar train is generally made up of three to five trailers, and total length is longer, and when trailer adopts front-wheel steering, the turn radius that very difficult acquisition is less, drawbar train can not meet the job requirements in narrow place.
Utility model content
For solving the problem, the utility model provides a kind of and has that turn radius is little, maneuverability, be applicable to the All-wheel Steering Device on Trailer of the transportation request in narrow place.
The utility model solves the technical scheme that its technical matters adopts: a kind of All-wheel Steering Device on Trailer, comprises vehicle frame, drawbar frame, forecarriage, front wheel spindle assembly, steering track rod, trailing truck, hind axle assembly.
The front portion of vehicle frame is located at by described forecarriage; Described trailing truck is located at the rear portion of vehicle frame.
The two ends of described steering track rod connect forecarriage, trailing truck respectively.
Described drawbar frame bearing pin is connected with forecarriage.
Described forecarriage is hinged on the anterior A point of vehicle frame by steering swivel vertical shaft, trailing truck is hinged on vehicle frame rear portion B point by steering swivel vertical shaft, draw bar bearing pin is connected with forecarriage, and the two ends of steering track rod are hinged on forecarriage C point, trailing truck D point respectively.Forecarriage is pulled to rotate when tractor truck turns to by draw bar, left and right front-wheel is turned to around the anterior A point of vehicle frame, pull trailing truck to rotate in the opposite direction by steering track rod simultaneously, because deflection angle is little, can be similar to and think that trailing or leading bogie rotates an identical angle, make left and right trailing wheel around vehicle frame rear portion B point counter steering, material is thus formed four-wheel steering.
The top of described forecarriage, the top of trailing truck are connected with vehicle frame, and the bottom of forecarriage, the bottom of trailing truck are connected with wheel, and forecarriage is anterior, trailing truck is anterior is connected with draw bar.
Preferably, the articulated manner of described forecarriage, trailing truck and vehicle frame adopts the one in special disk bearing, steering swivel vertical shaft.
Described steering swivel vertical shaft is as the hinge connecting forecarriage, trailing truck and vehicle frame, and bear vertical load with a thrust bearing, bear horizontal load with two angle bearings, this pattern cost is low, is applicable to domestic production.
Described steering swivel vertical shaft is provided with steering swivel vertical shaft, thrust bearing, angle bearing, sleeve.
The outside of angle bearing is located at by described sleeve.
The beneficial effects of the utility model: (1) All-wheel Steering Device on Trailer has that turn radius is little, the feature of maneuverability, is suitable for narrow place job requirements; (2) adopt steering swivel vertical shaft as the hinge of connecting vehicle frame with bogie truck, bear vertical load with a thrust bearing, bear horizontal load with two angle bearings, this pattern cost is low, applicable domestic production.
