Abstract
The utility model discloses a kind of tractors and semitrailer auxiliary connecting device, including camera (1), infrared generator (2) and display (3)；Camera (1), infrared generator (2) integrate, and are fixed on the center of tractor equalizing type of suspension crossbeam (4)；The center of semitrailer (6) is equipped with mark (5), makes the draw pin openings central alignment of infrared generator center and semitrailer；Display is mounted on bridge instrumentation platform, and camera (1), infrared generator (2) take electrical relay to power by reversing；Vision signal is passed to display by camera (1)；When the infrared ray that semitrailer center identification and infrared generator issue to just after can move backward and connect extension.The utility model can make driver observe directly tractor upper saddle seat and semitrailer traction pin shaft relative position, make driver no longer blind behaviour by rule of thumb, and can auxiliary direction driver operation, to improve the success rate that dress is hung.
Description
Technical field
The utility model belongs to tractor field, and in particular to a kind of tractor and semitrailer auxiliary connecting device.
Background technique
Tractor in transit, needs to connect semitrailer and is used together, and mode is by the saddle and half on tractor
The towing pin axis connection of trailer to together realize tractor and semitrailer connection, connection procedure be commonly called as dress hang.Some groups
User needs a tractor to be equipped with two semitrailers to guarantee conevying efficiency, i.e. a tractor is by semitrailer compartment from A
Point transports to B point, after unloading semitrailer compartment, hangs up another semitrailer for having installed cargo in B point and transports, this allows for leading
Draw car team vehicle and need frequently to unload extension, dress extension, currently, it is that a people is needed to operate vehicle that dress, which is hung, refers under another positive vehicle of needs
It waves, two people of this operation needs merge for a long time and operator by virtue of experience arrives, and need not checking that saddle is led with trailer at present
Draw pin direction, the used time is longer, during filling extension, because the traction pin shaft of saddle and semitrailer on tractor is at driver
Blind spot, needing a personnel, bommand driving person little by little moves backward tractor to semitrailer stop position at the scene, and makes saddle
Seat is on reversing route with traction pin shaft, and slowly reversing makes the traction pin shaft of saddle and semitrailer on tractor be joined to one
It rises.Its real process Chang Yinwei commanding can not be synchronous with driver's thinking, and commanding, can not because of distance and visual angle reason
The traction pin shaft relative position of saddle and semitrailer on accurate judgement tractor, driver are blind behaviour again, need repeated multiple times
Achievable dress is hung, and a large amount of time is wasted.It exists simultaneously a driver and individually fills extension in the case where no commanding
Situation, at this moment need driver repeatedly get off the saddle and semitrailer observed on tractor traction pin shaft position, it is blind to determine
Route is grasped, such case equally needs the achievable dress of repeated multiple times ability to hang, and reports the loss in the presence of dress and lose damage semitrailer and tractor
The case where.
Utility model content
The utility model provides a kind of tractor and semitrailer auxiliary connecting device, solves in tractor upper saddle seat and semi-mounted
When the traction pin shaft docking of vehicle, problem not easy to operate.
In order to solve the above technical problems, the utility model provides a kind of tractor and semitrailer auxiliary connecting device,
It is characterized by comprising camera 1, infrared generator 2 and displays 3；Camera 1, infrared generator 2 are integrated in one
It rises, is fixed on the center of tractor equalizing type of suspension crossbeam 4；The center of semitrailer 6 is equipped with mark 5, makes infrared generator
The draw pin openings central alignment at center and semitrailer；Display is mounted on bridge instrumentation platform, and camera 1, infrared ray occur
Device 2 takes electrical relay to power by reversing；Vision signal is passed to display by camera 1；When semitrailer center identification with it is red
The infrared ray that outside line generator issues connects extension to that can move backward after just.
The utility model has the advantages that the utility model can make driver observe directly the towing pin of tractor upper saddle seat and semitrailer
The relative position of axis, makes driver no longer blind behaviour by rule of thumb, and can auxiliary direction driver operation, to improve the success that dress is hung
Rate.
Detailed description of the invention
Fig. 1 is the electrical schematic of the utility model；
Fig. 2 is the scheme of installation of the utility model；
Fig. 3 is the installation rearview of the utility model；
Fig. 4 is cabin interior installation diagram；
Fig. 5 is operation display process schematic.
Specific embodiment
To keep the purpose of this utility model, content and advantage clearer, below to the specific embodiment party of the utility model
Formula is described in further detail.
The utility model proposes a kind of tractor and semitrailer auxiliary connecting device, including camera 1, infrared ray occur
Device 2, display 3；
Camera 1, infrared generator 2 integrate, and are fixed on the center of tractor equalizing type of suspension crossbeam 4；
The center of semitrailer 6 is equipped with mark 5, corresponding with infrared generator position, makes infrared generator center and semitrailer 6
Draw pin openings central alignment；
Display is mounted on bridge instrumentation platform,
Camera 1, infrared generator 2 take electrical relay to power by reversing, when reversing takes electrical relay input reversing
It when signal, closes the switch, realizes power supply；
Vision signal is passed to display by camera 1；When semitrailer center identification issue with infrared generator it is red
Outside line connects extension to that can move backward after just.
For vehicle at reverse gear position, display screen 3 shows the position of semitrailer and infrared ray on semitrailer, by adjusting traction
Vehicle direction, infrared ray is projected on semi-trailer traction pin, keeps infrared ray on towing pin during vehicle backing, tractor
With semitrailer can a successful connection, operation display process see Fig. 4,5.
The utility model can be observed on tractor by camera at frame cross on driving indoor display screen
The relative position of the traction pin shaft of saddle and semitrailer, has cleared away the blind spot of driver.
Simultaneously by laser emitter, the opposite of the traction pin shaft of the saddle draw pin openings and semitrailer on tractor is calibrated
Position, auxiliary driver finely tune steering operation, reduce dress and hang difficulty, substantially increase driver and fill and hang success rate, when saving
Between, it improves efficiency, and avoid saddle pin hole and towing pin not in the case where just, causing saddle to damage or by semi-trailer support
Bending.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
