Abstract
The utility model discloses a towing mechanism of a semi-trailer tractor, which comprises steadiers fixed on the tractor; wherein, a towing base plate which can support a semi trailer is articulated with the steadiers; an articulated shaft located at the articulated position is horizontal and perpendicular to the advancing direction of the tractor; the towing base plate is provided with a reverse V-shaped socket; a towing pin is fixed on the semi trailer and can be inserted in the socket in the towing base plate; and the towing base plate is also provided with a towing pin-locking unit. Only two degrees of freedom for rotation around the towing pin and swing around the articulated shaft are allowed between the semi trailer and the tractor, and other degrees of freedom are restricted. The utility model resolves the defect that only one degree of freedom for the advancing direction of the triangular towing frame is restricted, as a result, running becomes stable, braking becomes rapid, the towing reliability is greatly improved, and therefore the running safety is enhanced.
Description
Technical field
The utility model relates to a kind of hitch structure of trac..
Background technology
The tractor traction trailer transportation operation of prior art all adopts triangle drawbar frame structure to connect, the reliability of traction is relatively poor, the compartment swings bigger in driving, when meeting emergency brake or uphill/downhill, the inertia in compartment can be given the extra impulsive force of trac., car very easily takes place turn over the grave accident that the people dies.
The utility model content
Technical problem to be solved in the utility model provides a kind of semi-trailer tractor traction device reliable, traffic safety that connects.
For solving the problems of the technologies described above, the technical solution of the utility model is: semi-trailer tractor traction device, comprise the bearing that is fixedly mounted on the trac. machine, be hinged with the traction seat board that supports the semi-mounted wagon box on the described bearing, the jointed shaft level of described hinged place and perpendicular to the trac. working direction, described traction seat board is provided with down " V " type socket, be installed with towing pin on the described semi-mounted wagon box, described towing pin is plugged in the interior socket of described traction seat board, also is provided with the towing pin latching device on the described traction seat board.
As a kind of improvement, described towing pin latching device comprises joystick, with described traction seat board pivotally attached fork, one end and the described joystick of described fork are hinged, also be hinged with the towing pin lock dog that is inserted into down " V " type socket on the described fork, lock dog also be installed between described fork and the described traction seat board keep spring; " V " type spigot that falls of described traction seat board also is equipped with " U " type latch hook, between described latch hook and the described traction seat board latch hook retracing spring is installed.
Owing to adopted technique scheme, semi-trailer tractor traction device, comprise the bearing that is fixedly mounted on the trac. machine, be hinged with the traction seat board that supports the semi-mounted wagon box on the described bearing, the jointed shaft level of described hinged place and perpendicular to the trac. working direction, described traction seat board is provided with down " V " type socket, is installed with towing pin on the described semi-mounted wagon box, described towing pin is plugged in the interior socket of described traction seat board, also is provided with the towing pin latching device on the described traction seat board; Only have between semi-mounted wagon box and the trac. around the towing pin rotation with around two degree of freedom of jointed shaft swing, other degree of freedom has obtained restriction; Overcome the only degree of freedom of the working direction defective that obtains limiting of triangle drawbar frame, train stability, brake rapidly, the reliability of traction is greatly improved, and therefore improved traveling security.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, semi-trailer tractor traction device, comprise the bearing 1 that is fixedly mounted on the trac. machine, be hinged with the traction seat board 2 that supports the semi-mounted wagon box on the described bearing 1, the jointed shaft level of described hinged place and perpendicular to the trac. working direction, described traction seat board 1 is provided with down " V " type socket, is installed with towing pin 3 on the described semi-mounted wagon box, described towing pin 3 is plugged in the socket in the described traction seat board 1, also is provided with the towing pin latching device on the described traction seat board 1.
Described towing pin latching device comprises joystick 41, with described traction seat board 2 pivotally attached forks 42, one end and the described joystick 41 of described fork 42 are hinged, also be hinged with the towing pin lock dog 43 that is inserted into down " V " type socket on the described fork 42, lock dog also be installed between described fork 42 and the described traction seat board (2) keep spring 44; " V " type spigot that falls of described traction seat board 1 also is equipped with " U " type latch hook 45, between described latch hook 45 and the described traction seat board 2 latch hook retracing spring 46 is installed.
Its principle of work is as follows:
When joystick outwards is drawn out, lock dog is moved to the left under the effect of fork 42, and latch hook rotates around towing pin under the effect of spring, opens opening, the towing pin that be contained on the wagon box this moment just can separate with tractor mounted traction seat, reaches the purpose that car separates with the railway carriage or compartment.When needs in conjunction with the time, open the latch hook opening, towing pin enters along " V " type socket that falls of traction seat, latch hook rotates around pin under the effect of towing pin, lock dog loses the support of latch hook and is moved right by fork by spring, realizes self-locking.
Use trac. transportation unit of the present utility model, semi-mounted wagon box part weight is pressed on the tractor traction device, realizes half carrying, has improved the combination stability of wagon box and main frame, therefore and improved resistance to overturning during trac. transportation unit travels, realize the purpose of safety traffic.
