Description

A kind of superimposed trailer linked steering system
Technical field
The utility model relates to a kind of superimposed trailer system, especially relates to a kind of superimposed trailer linked steering system.
Background technology
Superimposed trailer is that axletree places the vehicle's center of gravity back when the even stand under load of vehicle, and the trailer that level or vertical power can be delivered to the hookup of tractor truck is housed.Itself is unpowered, needs to rely on other vehicle tractions to travel, could the normal a kind of motorless on-road vehicle that uses.Be mainly used in carrying personnel, goods or other special purposes.
Existing large-scale semitrailer, trailing wheel does not have turning function.Because trailing wheel can not turn to, when Vehicle Driving Cycle arrives the highway section, sharp turn, will run into the difficult problem that turning to difficulty, even can cause the unpassable consequence of vehicle.Will limit like this range of use of superimposed trailer, increase the logistics cost of goods.
The utility model content
The deficiency that exists in order to overcome prior art, the utility model provide a kind of superimposed trailer linked steering system.
A kind of superimposed trailer linked steering system, described superimposed trailer links to each other with tractor truck by gooseneck section, described gooseneck section by the tractor truck saddle install on tractor truck, described linked steering system comprises traction pin plate rotating mechanism, the first oil cylinder, the second oil cylinder and the steering hardware that cooperates with the tractor truck saddle, described traction pin plate rotating mechanism is arranged on the gooseneck section of superimposed trailer, link to each other by connecting rod mechanism between traction pin plate rotating mechanism and the first oil cylinder piston, the first oil cylinder and the second oil cylinder are connected by oil pipe; Described steering hardware is arranged on the superimposed trailer Wheel shaft, and steering hardware is connected with the second oil cylinder piston.
Preferably, the connecting rod mechanism of stating comprises the first lever and pull bar, the first lever is fixed on gooseneck section by a middle part fulcrum, described the first oil cylinder quantity is two and is symmetrical arranged along the superimposed trailer longitudinal centerline, the first lever two ends link to each other with first oil cylinder piston respectively, pull bar one end is fixed on the first lever one end, and the other end is fixed on the traction pin plate rotating mechanism.
Preferably, described steering hardware comprises steering swivel and the piston crank mechanism that is connected with steering swivel, and described the second oil cylinder piston connects steering swivel by piston crank mechanism, and steering swivel connects the wheel stub.
Preferably, described piston crank mechanism links to each other with the second oil cylinder piston by the second lever, and the second lever is fixed on the semi-trailer frame chassis by a middle part fulcrum; Described the second oil cylinder quantity is two and is symmetricly set on superimposed trailer longitudinal centerline both sides that the second lever two ends link to each other with second oil cylinder piston respectively.
Preferably, the middle part fulcrum of described the first lever or the second lever is positioned on the superimposed trailer longitudinal centerline.
The utility model makes it become the axletree that turns to that can turn to by semitrailer axle is redesigned; Increase simultaneously the oil circuit control part, adopt the fluid pressure linkage technology, make the steering angle of tractor truck and trailing wheel keep coordinate synchronization, so just can easily tackle some narrower curved road surfaces, improved the degree of utilization of superimposed trailer.
The utility model can reduce the labour intensity of chaufeur, makes can handlingly greatly strengthening of vehicle, can easily tackle travelling of complicated highway section.
