Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Referring to Fig. 1, a kind of reach truck shock absorption device, comprise drive wheel 8 and the actuating unit that drives this drive wheel 8 to rotate, actuating unit is connected with vehicle frame by four-bar mechanism, four-bar mechanism comprises hinged successively connecting rod 1, connecting rod 23, connecting rod 45 and connecting rod 34, connecting rod 34 and connecting rod 1 are hinged, as shown in Figure 2.
Actuating unit is fixedly connected with connecting rod 34, and vehicle frame is fixedly connected with connecting rod 23.Actuating unit is drive motor 1, and drive motor 1 is fixedly mounted on the motor attachment point 41 of connecting rod 34.
Reach truck shock absorption device also comprises balance wheel 7; The hinged one end of connecting rod 45 and connecting rod 23 is provided with outward extending extension 51, and balance wheel 7 is connected with extension 51 by spring.Connecting rod 45 forms a leverage taking the hinge-point that is connected with connecting rod 23 as fulcrum, the two ends of leverage are respectively the balance wheels 7 of connecting rod 34 and extension 51.As shown in Figure 5, the support of balance wheel 7 is provided with connecting panel one, is fixed with connecting panel two on extension 51, spring one end is connected with connecting panel one, the other end is connected with connecting panel two, and one end of connecting panel one is hinged in rotating shaft, prevents that balance wheel 7 and connecting panel one from departing from from mechanism.
In the time of parallel motion, the hinge-point upward movement of drivening rod 45 and connecting rod 34, because the hinge-point that connecting rod 45 is connected with connecting rod 23, connecting rod 23 and vehicle frame are all fixed, transports merit downwards so the extension 51 of the connecting rod 45 of right-hand member is understood.Because balance wheel 7 is connected by spring with extension 51, so can compress the spring on balance wheel 7, make it stress balance, can play good buffer action.Otherwise in the time that running into protruding or recessed road surface, balance wheel 7 also can drive parallel motion, like this when vehicle can reach good damping effect in the situation that running into certain scraggly road surface.
More excellent, as shown in Figure 3, four hinge-points of connecting rod 1, connecting rod 23, connecting rod 34 and connecting rod 45 form a parallelogram, and connecting rod 23 and connecting rod 34 are one group of opposite side of parallelogram.Connecting rod 23 and Frame Welding, this connecting rod is fixed, is equivalent to tetragonal b limit for maintaining static, other three limits all can freely be rotated around bearing pin.The opposite side of parallelogram is parallel all the time, under the changeless condition of connecting rod 23, the angle and direction of connecting rod 34 also can not change, thereby can run-off the straight, can run-off the straight with the drive motor 1 of connecting rod 34 welding yet, realize and prevent the object that drive wheel 8 tilts.Suppose the now initial condition for car load, when drive wheel 8 in the process at Vehicle Driving Cycle has run into a protruding road surface, drive wheel 8 will upward movement, i.e. motor attachment point 41 upward movements in figure, drivening rod 34 upward movements, and connecting rod 34 thus can run-off the straight.
Fig. 4 is the variable condition figure of four-bar mechanism, simulated motion is as shown in the figure: the high Xmm of projection that supposes road surface, now drive wheel 8 Xmm that risen, connecting rod 34 Xmm that also risen, because connecting rod 23 is fixed, so connecting rod 1 and connecting rod 45 can rotate around bearing pin, rise to the place shown in the figure on Fig. 5 the right, be equivalent to parallelogram by " flattening ", but connecting rod 34 can the run-off the straight along with the rising of position, so drive wheel 8 can remain vertical state.
More excellent, reach truck shock absorption device also comprises damping spring 6, and damping spring 6 one end are connected with connecting rod 23, and the other end is connected with connecting rod 45.As shown in Figure 6, connecting rod 1, connecting rod 23, connecting rod 34 and connecting rod 45 all have two groups, two connecting rods 23 connect by pipe link, two connecting rods 45 connect by base, pipe link is provided with the baffle plate being bolted, damping spring 6 is arranged between baffle plate and base, one end is connected with baffle plate, the other end is connected with base, is also provided with guide rod on baffle plate, and damping spring 6 is sleeved on guide rod, play the effect that damping spring 6 is led, base is provided with the through hole suitable with guide rod, and in damping spring 6 compression processs, guide rod can pass this through hole.
Can there is deformation along with the rising of connecting rod 1 in damping spring 6 in whole process, play damping, buffering effect, and the vertical position of connecting rod 23 can not change in whole process, because connecting rod 23 and vehicle frame are can not being subjected to displacement of welding, so car load is very stable in this process, vice versa.Therefore can in whole process, can play the effect of good damping.
More excellent, connecting rod 45 is straight-bar, connecting rod 23 is " Z " font, the stage casing of the equal vertical links 23 of two end portions of connecting rod 23, the two ends of connecting rod 23 are hinged with connecting rod 1 and connecting rod 45 respectively, the stage casing vertical links 45 of connecting rod 23, damping spring 6 vertical links 45.Object is better fixing for the damping spring 6 middle and connecting rod 45, and damping spring 6 vertical links 45 make mechanism's damping spring 6 in deformation process vertically stressed, and damping effect is better.
More excellent, connecting rod 34 is " C " font, and connecting rod 34 two ends are hinged with connecting rod 1 and connecting rod 45 respectively, and the inner side of connecting rod 34 bendings forms the space that holds drive wheel 8, and compact conformation, takes up room little.
In practical application, the elasticity modulus of each spring can carry out type selecting according to the quality of car load and load-carrying, and subsidiary control apparatus that can regulating spring initial length on each spring, reaches best damping effect with this.
The utility model also provides a kind of reach truck with above-mentioned reach truck shock absorption device.
Adopt after above-mentioned structure, be hinged by the four-bar linkage being parallel to each other, ensure that driver element is merely able to vertical moving up and down, the situation that there will not be driver element to tilt.On connecting rod 45, be also provided with balance wheel 7 and spring, when driver element is during with road surface convexo concave vertical tremor, reduce the vibration influence to car load.The vibrations of car load are reduced in a very little number range, very little to the vibration feeling of steerman in the time of reply general depot road surface, also can be good at protecting the part on car load to avoid the damage being shaken and affect service life.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
