Description
Technical field
The utility model relates to tractor-truck, is specifically related to a kind of light-weight tractor saddle.
Background technology
Along with the fast development of highway in China transport undertaking and automobile trail-mobile universal, superimposed trailer has become the main conveyance of road freight.Tractor-truck is equipped with special device for drawing the commercial vehicle of superimposed trailer, comprises the tractor truck with power-handling capability and be pulled the trailer without power-handling capability that car walks in tow.The connection mode of tractor truck and trailer has two kinds, is semi-mounted respectively and complete hangs, and wherein semi-mounted is that the front portion of trailer rides on the tractor truck saddle of tractor truck back segment, and tractor truck bridge below bears a part of weight of trailer.Above-mentioned tractor truck saddle is the vitals on superimposed trailer, not only play a part traction superimposed trailer and bear superimposed trailer load, also should be able to stand to start to walk simultaneously, accelerate, slow down, turn to, the operating condition such as braking and mounting superimposed trailer time impact, therefore the intensity of traction seat and reliability will directly affect the driving safety of superimposed trailer.
Tractor truck saddle is formed with the supporting seat being arranged on saddle bottom primarily of the saddle of band V-arrangement open slot.At present, often there is following problem in tractor truck saddle: 1. because most tractor truck saddle all adopts Plate Welding to form, heavier mass, the weight of traction seat and the weight of trailer be all by tractor truck after bridge bear, and the bearing capacity of tractor truck car bridge is below by greatest extent, therefore, heavier tractor truck saddle, will certainly affect the carrying capacity of trailer.2. when using, the position that tractor truck saddle contacts with trailer needs charging-up lubricant oil fat to lubricate usually, in order to avoid wearing and tearing.3. the hanging structure of existing tractor truck saddle comprises the U-shaped fixture block be rotatably connected on supporting seat, the connecting rod that can offset with U-shaped fixture block lateral surface, with the crank of rod hinge connection, drive the control lever of crank-operated, wherein crank is located in bar hole that supporting seat is arranged and is led by bar hole, during trailer mounting, pull joystick, control lever is retreated, control lever drives crank to move along bar hole, crank handle turns link work, connecting rod and U-shaped fixture block depart from, U-shaped fixture block rotates an angle, its opening and V-arrangement open slot basically identical, now tractor truck retreats, until the V-arrangement open slot of the bearing pin of trailer in the middle part of saddle is connected in above-mentioned U-shaped fixture block, under the effect of bearing pin impulsive force, U-shaped fixture block is by return, now promote control lever, connecting rod is made to prop up U-shaped fixture block.Above-mentioned hanging structure have employed brace and connecting rod framework, and in order to make crank stable when moving, also bar hole structure need be set especially on supporting seat, there is baroque problem, and after U-shaped fixture block return, need manually to promote control lever and could realize again offseting of connecting rod and U-shaped fixture block, operation is inconvenient.
Utility model content
The utility model provides a kind of light-weight tractor saddle, and to solve existing tractor truck saddle Heavy Weight, hanging structure is complicated, unhandy problem.
This programme is as follows: a kind of light-weight tractor saddle, comprise saddle and the supporting seat being arranged on saddle bottom, the side direction of saddle is provided with the open slot of V-arrangement, open slot makes saddle form two with the block flap of open slot symmetry, below supporting seat being positioned at saddle is provided with hanging structure, described hanging structure comprises the U-shaped fixture block be connected by axis of rotation with described supporting seat, saddle is the pedestal that integral type aluminum magnesium alloy is made, described hanging structure also comprises and can move and the push rod pinned along perpendicular to mounting direction, the side of push rod can offset with the lateral surface of described U-shaped fixture block, described push rod has bar hole along the direction vertical with mounting, supporting seat is provided with guide pillar, described guide pillar is positioned at described bar hole.
This programme principle of work is as follows: when mounting trailer, direct pull-out push rod, the side of push rod and the lateral surface of U-shaped fixture block depart from, and U-shaped fixture block rotates an angle, its opening and V-arrangement open slot basically identical, now tractor truck retreats, until the V-arrangement open slot of the bearing pin of trailer in the middle part of saddle is connected in above-mentioned U-shaped fixture block, under the effect of bearing pin impulsive force, U-shaped fixture block resets, now push push rod, make the side of push rod again prop up the lateral surface of U-shaped fixture block.Under coordinate of guide pillar with bar hole, guide pillar plays the effect of guiding to push rod.
The pedestal that the utility model saddle adopts integral type aluminum magnesium alloy to make, lightweight, make trailer have higher load-carrying; And eliminate brace and connecting rod framework in hanging structure, structure is simple, and cost is low.
Further, the position that the upper surface of saddle contacts with trailer is provided with one deck nylon layer.Nylon material has the high feature of intensity, not easy to wear, so just without the need to using lubricating oil at saddle and trailer contact site again, cost-saving.
Further, the side direction of push rod is provided with the draw-in groove that push rod can be made to pin, and draw-in groove can be connected on supporting seat.Draw-in groove is set, when after pull-out push rod, by draw-in groove is connected to locking tappet rod on supporting seat, conveniently carries out the mounting operation of lower step.
Further, between guide pillar and the inwall of bar hole end, spring is provided with.Spring has makes the automatically reset effect of push rod, like this when manually being pulled out by push rod, when trailer mounting is complete, directly unclamps push rod, and the push rod side that automatically resets under the action of the spring props up the lateral surface of U-shaped fixture block, easy to operate.
Further, the utility model block flap bends downwards.
