Abstract
The invention relates to a suspension device for a modular hydraulic flat car, which comprises hanging units and an axle, wherein the hanging units are connected with a flat car frame; the axle is connected with the hanging units; each hanging unit comprises a cantilever, a balance arm and a fuel tank, wherein the cantilever is directly connected with the flat car frame; the balance arm is respectively connected with the cantilever and the axle by connecting pieces; and the number of the hanging units is two and the two hanging units are simultaneously connected with one axle. According to the suspension device, required support force which is big enough can be provided for automobiles. Meanwhile, the function of integrally lifting and lowering the automobiles is reserved, and the manufacture cost of the hanging system is effectively lowered and assembling workload is reduced while each axis is guaranteed to bear even pressure.
Description
Technical field
The present invention relates to the extraordinary heavy die block formula hydraulic flat car of road transport, particularly relate to a kind of suspension gear of modular hydraulic flat truck.
Background technology
The flat truck suspension gear is one of important composition of vehicle, mainly flexibly couples together vehicle frame or vehicle body and wheel, is 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.
At present, the suspension of known module hydraulic flat car generally is by cantilever, the equilibrium arm that is connected with cantilever, is connected to parts such as oil cylinder and vehicle bridge on cantilever and the equilibrium arm and constitutes.Wherein, Cantilever generally is connected through swing bearing with vehicle frame or the bearing of cantilever indirectly-acting on projecting shaft connects; Swing bearing drives cantilever and can turn round to reach not only, and the function that can go up and down again is because cantilever need turn to; Be easy to cause torsional deflection, cantilever easy and vehicle frame generation interference when revolution simultaneously; Equilibrium arm then is connected through bulb with oil cylinder, and the lubricating system of oil cylinder ball head structure is bad, maintenance, maintenance difficulty, more easy abrasion; Last each cantilever, equilibrium arm only act on a vehicle bridge, and the impulsive force that each equilibrium arm bears is huge, damage easily.
Summary of the invention
The present invention provides a kind of suspension gear of modular hydraulic flat truck.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of suspension gear of modular hydraulic flat truck; It comprises the suspension unit that is connected with the flat truck vehicle frame, the vehicle bridge that is connected with described suspension unit; Described suspension unit comprises: cantilever, equilibrium arm and fuel tank, described cantilever and vehicle frame be direct connection mutually, and described equilibrium arm is connected with vehicle bridge with described cantilever respectively through attaching parts; Described suspension unit is provided with two, and two described suspension units are connected with a described vehicle bridge simultaneously.
Preferably, described oil cylinder comprises hanging oil cylinder and turns to oil cylinder.
Further preferably, described hanging oil cylinder is connected with equilibrium arm with described cantilever respectively through attaching parts.
Further preferably, the described oil cylinder that turns to is connected with vehicle bridge with described equilibrium arm respectively.
Preferably, described attaching parts is a bearing pin.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
The present invention can provide needed enough big bearing force for vehicle, has kept the whole liter of vehicle, whole function of falling simultaneously, guarantees every uniform while of axis pressure, effectively reduces the manufacturing cost and the work capacity that reduces assembling of suspension.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the structural representation of vehicle bridge part of the present invention.
Wherein: 1, suspension unit; 2, vehicle frame; 3, cantilever; 4, equilibrium arm; 5, vehicle bridge; 6, hanging oil cylinder; 7, turn to oil cylinder; 8, bearing pin.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Like the suspension gear of Fig. 1, a kind of modular hydraulic flat truck shown in 2, it comprises the suspension unit 1 that is connected with flat truck vehicle frame 2, the vehicle bridge 5 that is connected with suspension unit 1.Suspension unit 1 generally comprises: cantilever 3, equilibrium arm 4 and fuel tank.
In the present embodiment, cantilever 3 is arranged on vehicle frame 2 belows, and with vehicle frame 2 direct connection mutually, excessive swing bearing no longer is set, vehicle frame 2 is wholely set with suspension unit 1 mutually; One end of equilibrium arm 4 is connected with cantilever 3 bottoms through bearing pin 8, and the other end also is connected with vehicle bridge 5 through bearing pin 8, substitutes original equilibrium arm 4 and cooperates with the axis hole of vehicle bridge 5.Suspension unit 1 is provided with two altogether; I.e. two cantilevers 3 and equilibrium arm 4 acting on the same vehicle bridge 5 of symmetry simultaneously; Make cantilever 3 stressed even through complementation; Independent one group of cantilever 3, equilibrium arm 4 bear huge impact power before having avoided, and also can adjust the core wheel distance and the distance of shaft centers of two cantilevers 3 as required.Oil cylinder comprises with hanging oil cylinder 6 and turns to oil cylinder 7: hanging oil cylinder 6 is separately fixed on cantilever 3 and the equilibrium arm 4 through bearing pin 8; And turn to oil cylinder 7 to act on respectively on equilibrium arm 4 and the vehicle bridge 5, and turn to through turning to oil cylinder 7 to drive vehicle bridge, avoided traditional hanging oil cylinder 6 promptly need go up and down and need turn to and the influence that brings.
When work, when unidirectional or two-way horizontal wall inscription and uneven situation appearred in smooth running, cantilever 3 can be afforded redress by hanging oil cylinder 6 with vehicle bridge 5 at random, to adapt to the clear condition of ground-surface, keeps the car load smooth running to greatest extent, has slowed down the distortion of vehicle frame 2 greatly; When car need turn to; Turn to by turning to oil cylinder 7 to provide steering power directly to drive vehicle bridge 5; Drive the torsional deflection that cantilever 3 causes cantilever 3 through swing bearing before having solved, also need not consider that the center of gyration scope of cantilever 3 and vehicle frame 2 produce interference simultaneously.
Like this, can satisfy the transportation request that multiple situation is got down the highway and subtracted greatly, can also guarantee less, than the narrow lane general work; And easy to use, time and fund have been practiced thrift in assembling easily, maintenance, maintenance.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
