Abstract
The utility model discloses an orientation device for backing vehicle which is used for an orienting rectilinear backing device of a semi-trailer train and which comprises a return spring, a guide slot plate, a slide wedge, a guide plate, a deflector rod, a cylinder, etc. The orientation device for backing vehicle is arranged in the style of separation, the compressed-air of a tractor is used as a medium. The utility model has the advantages of high rigidity, high strength and high reliability. The orientation device for backing vehicle also has the advantages that pulling dowel is convenient, the semiautomatic connection and disconnectment of the tractor is handy and the remote control can be independently completed by the driver without getting down. The utility model is fit for the long distance backing work under the condition of the narrow channel and the pecific environment of a highway, such as a station, a quay, a harbor, a freight yard, a ferry, a tunnel, etc.
Description
The utility model belongs to a kind of reversing gear of semi-trailer train.
At present, there is following defective in semi-trailer train aspect driving performance: one, superimposed trailer and tractor truck flexible, hinged, and degree of freedom is very big, and during reversing, the trailer rear axle is difficult to the palm to the steering response effect of tractor truck front axle, and servo difficulty is big.Two, the vertical and laterally existence of pivot angle of traction seat device.Give the bigger difficulty that increased accurately in place of moveing backward.Three, turn radius is big, and passage requires wide, and trafficability characteristic is poor, falls back when travelling, and sails the territory and is very restricted.Four, semi-trailer train is in complicated and reversing in particular cases, and chaufeur often needs to take a long time, and under the nervous psychology state, glances right and left, and the frequent commutation in a rush ground is repeatedly advanced and retreat, come and gone, and could realize the reversing purpose.
Task of the present utility model is to overcome the defective of above-mentioned semi-trailer train reversing, and a kind of failure-free easy and simple to handle, directed directed interlock system of moveing backward is provided.
The utility model is the unpack format installation and adopts the pressurized air of tractor truck to make medium, realizes Long-distance Control.Now be described below in conjunction with the accompanying drawings:
Crossbeam (2) and connecting panel (11) with rivet be connected in put the beams in place before the semi-trailer frame on, work to support whole device.Cylinder (1) and driving lever support (5) by screw to prizing in the both sides of crossbeam (2).Pull back spring (3) is sleeved on the piston rod by shaft clevis (4), plays return security personnel effect.Guide plate (8) is screwed below connecting panel (11), and stuck with two locating pieces (12), to bear cross shear.Sliding wedge (7) is loaded in the guide plate (8) by cover plate (10) is sliding.Because the cross section of sliding wedge (7) is rectangular, front end adopts 30 ° of angles of wedge, the centre has two cambered surface rectangle slotted eyes, makes device can bear bigger transverse shearing force, can play tight preferably lock effect again, both slow down the side direction moment of flexure on the piston rod, increased the alerting ability of action again.Driving lever (9) is movably hinged with driving lever support (5), shaft clevis (4) respectively with two lateral pins, and insert within sliding wedge (7) its lower end, and driving lever (9) part of etc.ing constitutes increases a times mechanism, makes sliding wedge (7) acquisition increasing stroke doubly.When driving lever (9) is in non-chain state, be subjected to the thrust of pull back spring (3), make sliding wedge (7) often remain on retracted position, make that the device return is reliable, security insurance.Directed frid (6) is installed in the traction seat rotating disk V-arrangement prong of tractor truck with screw.Directed transverse slat (6) be half garden shape to deciding face, notch is 30 ° of angles of wedge, the former can make sliding wedge (7) self-alignment low water in ± 25 ° of scopes, the latter can play the effect of failure-free wedge yoke.Whole directed frid (6) can significantly be strengthened the intensity of traction seat rotating disk.
When connecting source of the gas, pressurized air is by being installed on the commutation air valve in the operator's compartment, B chamber (the seeing accompanying drawing 1) driven plunger that enters cylinder (1) advances left, thereby drive driving lever (9) motion, because driving lever (a 9) upper end hinge, therefore its lower end can only be swung left around last fulcrum, meanwhile, stir sliding wedge (7) to left movement, when being in straight line before and after tractor truck and the superimposed trailer, voussoir (7) is wedged rapidly in the prong of directed frid (6) under gas pressure, limits its degree of freedom, car body becomes a rigid unitary by flexibly connecting interlocking before and after making, because teeter is tied, reversing this moment, semi-trailer train then orientation linearly travels.Otherwise, the conversion air valve, pressurized air then then enter the A chamber of cylinder (1), the piston right lateral makes the right pendulum in driving lever (9) lower end, stirs sliding wedge (7) right lateral finger.At this moment, tractor truck and superimposed trailer constraint relief affranchise once again, and train and being flexibly connects, and recovers its original characteristic.
In sum, the utility model has the advantages that: one, compact conformation, easy to maintenance, good rigidly, intensity height.Two, can realize smoothly that tractor truck is connected with the S. A. of superimposed trailer and takes off extension.Three, easy and simple to handle.Four, interlocking is reliable.Five, can realize the reversing purpose rapidly and accurately, especially be adapted to AT STATION, passages such as harbour, harbour, goods yard, ferry, tunnel are narrow, the length under the road conditions particular surroundings is apart from the straight line car-backing operation.
