Abstract
The utility model relates to a hanging device of a module type hydraulic flat car, which comprises two hanging units connected with a frame of the flat car and an axle connected with the hanging units, wherein each hanging unit comprises a suspension arm, a balance arm and an oil tank, the suspension arm is directly connected with the frame, the balance arm is connected with the suspension arm and the axle through connecting pieces, the two hanging units are simultaneously connected with the axle. The hanging device can provide large enough needed support force for the car, maintain the functions of ascending and descending the car entirely, guarantee each axis to bear even pressure, and effectively lower manufacturing cost of a hanging system and assembling workload.
Description
Technical field
The utility model relates to the extraordinary heavy die block formula hydraulic flat car of road transport, particularly relates 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 vehicle frame or vehicle body and wheel is flexibly coupled together, and 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 on cantilever and the equilibrium arm and vehicle bridge and is constituted.Wherein, cantilever generally is connected by 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, function that again can lifting, 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 by bulb with oil cylinder, and the lubricating system of oil cylinder ball head structure is bad, maintenance, maintenance difficulty, easier wearing and tearing; 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 utility model provides a kind of suspension gear of modular hydraulic flat truck.
For achieving the above object, the technical solution adopted in the utility model 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, described equilibrium arm is connected with vehicle bridge with described cantilever respectively by 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 by 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 utility model compared with prior art has following advantage:
The utility model 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 of suspension and reduces the work capacity of assembling.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of the utility model vehicle bridge part.
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 drawings and Examples the utility model is further described:
The suspension gear of a kind of modular hydraulic flat truck as shown in Figure 1, 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 mutually with suspension unit 1; One end of equilibrium arm 4 is connected with cantilever 3 bottoms by bearing pin 8, and the other end also is connected with vehicle bridge 5 by 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 by 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 by 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 by turning to oil cylinder 7 to drive vehicle bridge, avoided traditional hanging oil cylinder 6 promptly to need lifting need turn to again and the influence that brings.
When work, when unidirectional or two-way horizontal wall inscription and uneven situation appearred in smooth running, cantilever 3 and vehicle bridge 5 can be afforded redress by hanging oil cylinder 6 at random, to adapt to the clear condition of ground-surface, keep the car load smooth running to greatest extent, have 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 by swing bearing before having solved, also do not need to 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 saved in assembling easily, maintenance, maintenance.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present 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 present utility model.
