The single-cantilever suspension mechanism comprises a suspension unit and wheel tires, wherein the suspension unit is connected with a vehicle frame, the wheel tires are connected with the suspension unit;the suspension unit comprises a suspension frame, a balance arm and a suspension oil cylinder, the suspension frame is connected with the vehicle frame, two end parts of the balance arm are respectively connected with the suspension frame and the wheel tires; the suspension oil cylinder comprises an oil cylinder body and a piston rod matched with the oil cylinder body, the end part of the oil cylinder body is connected with the suspension frame, the end part of the piston rod is connected with the balance arm, a suspension hanging plate is rotatablely connected onto the suspension frame, a hanging hole is formed in the suspension hanging plate, and a hanging buckle is connected onto the balance arm and can be clamped and arranged in the hanging hole. The single-cantilever suspension mechanism has the advantages that the suspension appearance size is small, the suspension lifting stroke is great, the size is small, the weight is light, the carrying capability is high, the integral structure is reasonable, the installation, the maintenance and the repair are convenient, and the like.
Description
Technical field
the utility model relates to a kind of flat truck that is applicable to the big part of carrying, particularly relates to a kind of flat truck single-arm suspension mechanism.
Background technology
suspension gear is one of important composition of engineering truck; Mainly flexibly couple together vehicle frame or vehicle body and wheel; Be used for a shear force and the moment of transfer function between wheel, vehicle frame, to relax the impact that uneven road surface passes to vehicle frame.
flat truck is a kind of common vehicle of road transport, because large-scale, the heavy goods of its more convenient loading and unloading, and than other kinds vehicle of same size, can load more goods, receives the favor of traffic unit deeply.At present, the used suspension of known flat truck mainly is non-cantilevered, and it mainly installs two or four tires, lays respectively at the hanger bracket both sides, the structure more complicated, and volume is also bigger.
Summary of the invention
The purpose of
the utility model provides a kind of flat truck single-cantilever hitch.
For achieving the above object, the technical scheme that the utility model adopts is:
a kind of flat truck single-cantilever hitch; It comprises the suspension unit that is connected with carriage frame, the wheel tyre that is connected with described suspension unit; Described suspension unit comprises: hanger bracket, equilibrium arm and hanging oil cylinder; Described hanger bracket is connected with described carriage frame, and the both ends of described equilibrium arm are connected with wheel tyre with described hanger bracket respectively; Described hanging oil cylinder comprises cylinder block, the piston rod that matches with described cylinder block; The end of described cylinder block is connected with described hanger bracket; The end of described piston rod is connected with described equilibrium arm; Be rotatably connected to suspension plate on the described hanger bracket, offer lifting hole(eyelet) on the described suspension plate; Be connected with on the described equilibrium arm and withhold, described withholding can be fastened in the described lifting hole(eyelet).
preferably, described each described suspension unit connects a wheel tyre.
further preferably, described suspension unit is arranged on a side of described wheel tyre.
preferably, described withholding is nut or nut.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
What the utility model adopted is the single-cantilever hitch, and whole suspension unit only cooperates a tire, and tire is positioned at a side of suspension unit, adds that each swivel point position dimension of suspension unit counts carefully repeatedly, and the swivel point location arrangements is reasonable, and it has the following advantages:
(1), the suspension oad is little;
(2), the suspension lifting stroke is big;
(3), volume is little in light weight;
(4), load-carrying capacity is big;
(5), reasonable integral structure is convenient to install, maintains, keeped in repair.
Description of drawings
accompanying drawing 1 is the structural representation of the utility model.
wherein: 1, hanger bracket; 2, hanging oil cylinder; 20, cylinder block; 21, piston rod; 3, suspension plate; 30, lifting hole(eyelet); 4, equilibrium arm; 40, withhold; 5, carriage frame.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
A kind of flat truck single-cantilever hitch that
are as shown in Figure 1, it comprises the suspension unit that is connected with carriage frame 5, the wheel tyre that is connected with suspension unit.
in the present embodiment: suspension unit comprises: hanger bracket 1, equilibrium arm 4 and hanging oil cylinder 2, and its annexation is: hanger bracket 1 is connected with carriage frame 5; The both ends of equilibrium arm 4 are connected with wheel tyre with hanger bracket 1 respectively.
hanging oil cylinder 2 comprises cylinder block 20, the piston rod 21 that matches with cylinder block 20, and the end of cylinder block 20 is connected with hanger bracket 1, and the end of piston rod 21 is connected with equilibrium arm 4.
in addition, are rotatably connected to suspension plate 3 on the hanger bracket 1, on suspension plate 3, offer lifting hole(eyelet) 30; Be connected with on the equilibrium arm 4 and withhold 40, withholding 40 can be to be spun on nut on the equilibrium arm 4, nut etc., fixed thereon also passable fixed block etc.Each suspension unit connects a wheel tyre, and wheel tyre is positioned at a side of suspension unit.
Below set forth the work engineering of present embodiment down:
vehicle is through roughness pavement the time; Oil circuit can inject hydraulic oil or make hydraulic oil get back to oil circuit from cylinder block 20 in cylinder block 20; Make piston rod 21 stretch, contract and drive the rotation up and down of equilibrium arm 4; The platform plane and the ground-surface height that guarantee vehicle remain unchanged, and to adapt to the ground-surface situation, reach the automatic compensation function of suspension unit.
When
are shunk or need do not used when suspension unit,, whole suspension unit is sling, dwindled the oad of whole suspension unit withholding in 40 lifting hole(eyelet)s 30 that are fastened on the suspension plate 3 on the equilibrium arm 4.
the foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
