Abstract
The utility model discloses a front axle assembly of a trailer. A front axle of the front axle assembly is a steering axle with a left-turning draw rod and a right-turning draw rod. A connecting lever capable of rotating around a vertical axis is hinged to the middle of a cross beam of the front axle, the rear end of the connecting lever is hinged to the left-turning draw rod and the right-turning draw rod respectively, a front arm capable of swinging vertically is hinged to the front end of the connecting lever, and a traction ring hook is arranged at the front end of the front arm. Compared with a rotating disc type trailer, the trailer has the advantages that the gravity is lower, stability is better and space occupied by a chassis is smaller.
Description
Technical field
The utility model relates to the front axle assemble of a kind of trailer.
Background technology
Trailer mainly by chassis and on the compartment that sets firmly form, because adopting tractor truck, draws by trailer, its chassis should have the function turning to tractor truck, in order to meet this requirement, traditional trailer is mostly rotating disc type trailer, and as Chinese patent CN201863916U discloses a kind of rotating-disc type trailer chassis, the front end bottom of chassis skeleton is provided with the rotating disk that can rotate around vertical axis, rotating disk bottom is installed with a rotating disk bracket, and rotating disk bracket can rotate with rotating disk like this; Front end at rotating disk bracket is connected with triangle posture forearm by bearing pin, and the nose angle position of forearm is installed with traction bail, eye hitch is hooked on the hook at tractor truck rear portion and can realizes trailer traction.The trailer of this structure has forward and backward bridge, wherein propons is installed on rotating disk bracket and forms front axle assemble, and when tractor truck turns to, forearm drives the corresponding rotation of rotating disk bracket like this, and then the front vehicle wheel on drive propons is corresponding turns to, met trailer and turned to requirement, but owing to adopting rotating disk to turn to, rotating disk is bulky, car load space availability ratio is low, and rotating disk weight is heavier, add top bottom-disc center of gravity higher, stability is bad.
Utility model content
The purpose of this utility model is to provide the front axle assemble of a kind of trailer, the problem that weight is heavier, stability is bad that adopts rotary-disk type structure to cause in order to solve existing trailer chassis.
The utility model adopts following technical scheme: axle assemble before a kind of trailer, the propons of this front axle assemble is the steeraxle with left and right steering track rod, the crossbeam middle part of propons is hinged with the connecting lever that can rotate around vertical axis, the rear end of connecting lever is hinged with left and right steering track rod respectively, the front end of connecting lever is hinged with the forearm that can swing up and down, and the front end of forearm is provided with traction bail.
Crossbeam the place ahead of described propons is provided with carries out left and right spacing corner locating device to connecting lever, this device comprise take on connecting lever jointed shaft axis a bit as the arc track in the center of circle and be arranged on connecting lever, rail-guidedly mobilely coordinate that forearm is transferred to the aptamers on the skeleton of chassis to the pulling force of propons with described.
Described track is chute, described aptamers be inlaid in chute, with the adaptive slide block of chute guiding bearing fit.
Described chute has two, and two chutes are arranged at respectively on the positioning plate of two upper and lower positioned opposite, described adaptive slide block by two respectively corresponding be installed in connecting lever upper and lower surface, slide and be flush-mounted in two arc shaped sliders in chute and form respectively.
Adopt the front axle assemble of trailer of said structure, due to be hinged on connecting lever on propons crossbeam can with tractor truck turn to and corresponding rotating, and then drive two front vehicle wheels to turn to accordingly by two steering track rods of propons, compare rotating disc type trailer, center of gravity reduces, good stability, has reduced chassis simultaneously and has taken up room.

The specific embodiment
The embodiment of axle assemble before the utility model trailer: as Figure 1-5, whole front axle assemble arranges on the chassis skeleton 1 of trailer chassis, its propons is steeraxle, by controlling the steering track rod 2 being connected respectively with two front vehicle wheels 3 of propons, can realize the left and right of two front vehicle wheels 3 and turn to.Crossbeam 4 middle parts at propons are installed with the first hinged seat 9, on the first hinged seat 9, by the first bearing pin 8 on it, that axis vertically extends, be hinged with connecting lever 10, the rear end of connecting lever 10 is hinged with two steering track rod 2 ends of propons respectively, when connecting lever 10 rotation, can drive two front vehicle wheels 3 to turn to accordingly by two steering track rods 2 like this; Front end at connecting lever 10 is installed with the second hinged seat 15, on the second hinged seat 15, by the second bearing pin 6 on it, that axis extends along left and right directions, be hinged with triangle posture forearm 12, the front end of forearm 12 can swing up and down like this, at the front end of forearm 12, is provided with traction bail 7.
As further optimization, crossbeam 4 the place aheads of propons are provided with carries out the spacing corner locating device in left and right to connecting lever 10, this device comprises and is arranged on the first positioning plates 14 hinged seat 9 the place aheads, two upper and lower positioned opposite, described connecting lever 10 is through the gap between two positioning plates 14, positioning plate 14 is steel plate, its two longeron 13Shang， lower floor positioning plates that positioning plate is welded in chassis skeleton 1 are at the middle and upper levels fixed together by the bolt connecting between the two.On two positioning plates 14, offer respectively the arc chute 5 of take on the axis of the first bearing pin 8 a bit as the center of circle, two chute corresponding settings Shang Xia 5, in the slip of two interior guiding respectively of chute 5, being embedded with 11, two slide block 11 bolts of an arc shaped slider is separately fixed in the upper and lower surface of connecting lever 10; In the present embodiment, two chutes 5 have formed a track, two slide blocks 11 have formed an adaptive slide block, simultaneously, adaptive slide block be again the aptamers coordinating with track, dependence aptamers coordinate with the action of track can carry out connecting lever 10 left and right spacing, meanwhile, the pulling force of 10 pairs of propons of connecting lever can be transferred on chassis skeleton 1 by aptamers and track, thereby it is stressed to reduce propons.
During application, whole trailer hangs on the hook at tractor truck rear portion by traction bail 7, at tractor truck, drive in trailer moving process, the pulling force major part that tractor truck applies trailer is transferred on chassis skeleton 1 by corner locating device, thereby it is stressed to have reduced propons, swinging up and down of forearm 12 can reduce the moment of torsion that drawbar frame is subject to when tractor truck uphill/downhill.When tractor truck right-hand turning to time, forearm 12 drives connecting lever 10 dextrorotation, and connecting lever 10 and then two steering track rods 2 by propons drive respectively two front vehicle wheel 3 right steerings, when adaptive slide block slides to the right-hand member of chute 5, front vehicle wheel 3 is in right steering maximum angle, as shown in Figure 4 state; When tractor truck left-handed turning to time, forearm 12 drives connecting levers 10 left-handed, connecting lever 10 and then two steering track rods 2 by propons drive respectively two front vehicle wheel 3 left steerings, when adaptive slide block slides to the left end of chute 5, front vehicle wheel 3 is in left steering maximum angle.
In above-described embodiment, track and aptamers adopt the fit form of chute slide block, and in other embodiments, track can be slide rail, and aptamers is the roller coordinating with slide rail accordingly.
Certainly in other embodiments, chute can be one, and corresponding slide block is also one.
