Abstract

The utility model discloses a traction device used for a haulage truck. An upright column extended downwards is arranged at the bottom part of a towing supporting plate of the traction device and is movably inserted in an axle hole of an intermediate plate, the upright column of the towing supporting plate is movably inserted in the axle hole of the intermediate plate to form a 360 degree revolute pair, the towing supporting plate and the intermediate plate are locked through an inserting pin to limit the relative rotation between the towing supporting plate and the intermediate plate and avoid tail wagging during the reversing process, both sides of the bottom part of the intermediate plate are pivotally connected with both sides of a connecting plate below through pins, the intermediate plate can reciprocate relatively to the connecting plate by taking the pins as the axle center, and the connecting plate is fixed on the truck body through a bolt. The utility model can cause one truck to tow a plurality of trucks, therefore, the efficiency of the haulage truck is improved, the economic efficiency is improved, the two trucks can relatively rotate for 360 degrees, even if a plurality of trucks are towed, and the turning is still flexible; and a plurality of trucks are locked linearly during the reversing process, and the phenomenon of tail wagging due to reversing cannot occur.

Description

The draw gear that a kind of haulage truck is used

Technical field

The utility model relates to a kind of draw gear, the draw gear that particularly a kind of haulage truck is used.

Background technology

At present, the transportation of commercial automobile, the for example transportation of commodity truck (be commonly called as and send car) generally is the negative truck A of the vehicle body overriding of a truck A, as shown in Figure 5, this kind transportation mode is subjected to the limitation in height in the traffic law, once only can transport two trucies, conveying efficiency is low, has increased traffic cost virtually.

Summary of the invention

The purpose of this utility model provides the draw gear that a kind of haulage truck is used, this draw gear is used for the transportation traction of truck, use this draw gear can make many trucies of a truck traction, improved the conveying efficiency of truck, reduced traffic cost, and this draw gear can make between two trucies and freely rotate, and turns flexibly.

The utility model is by the fixing traction supporting plate of truck propons, intermediate plate, connecting panel constitutes, the bottom of this traction supporting plate is extended with a column downwards, the centre of intermediate plate offers an axis hole, the column activity of traction supporting plate is plugged on and forms 360 ° revolute pair in the axis hole of intermediate plate, traction supporting plate bottom is extended with flange to the side, offer through hole on this flange, lead to the hole site with respect to flange on the plate face of intermediate plate also offers through hole, latch can mortise lock in two through holes, relatively rotating of restriction traction supporting plate and intermediate plate, the two bottom sides of intermediate plate is extended with two lugs respectively downwards, this two lug is provided with the horizontal vertical of direction and intermediate plate, two lugs offer axis hole, plate face two sides of connecting panel extend upward the lug with axis hole with respect to the position of lug, two side lugs of this connecting panel are plugged on respectively in the middle of two lugs of two sides of intermediate plate, and intert in axis hole with bearing pin, so, intermediate plate can be that rotate with respect to the connecting panel front and back in the axle center with this bearing pin, and connecting panel is by on the vehicle body that is bolted to truck.

When the utility model uses, connecting panel is fixed on the vehicle body of truck rear portion, then, the propons of back truck is placed on the traction supporting plate of the present utility model of front truck arrangement, and with this propons with the traction supporting plate be fixed together, the front-wheel of back truck is positioned on the vehicle body of front truck, the trailing wheel of back truck lands and can unpoweredly freely rotate, this back truck mode according to this continues to draw the truck of back, and the quantity of traction can be according to the regulation of the power size of needs, foremost tow truck and traffic law and decided.

The beneficial effects of the utility model are as follows:

1, a truck can draw many trucies, has improved the efficient of haulage truck, has increased economic benefit;

2, because of intermediate plate and connecting panel can before and after rotate, therefore can make the truck of back tilt to put, and trailing wheel lands and freely rotates, can 360 ° relatively rotate because of traction supporting plate and intermediate plate again, and can make between two trucies 360 ° to relatively rotate, even many trucies of traction, it is still flexible to turn;

3, because of can using latch locking between traction supporting plate and the intermediate plate, restriction relatively rotating between the two, can many trucies lockings when reversing linearly, the phenomenon of wagging the tail of moveing backward can not take place; When front haulage is advanced, extract latch and unlock.
