Shock mitigation system behind the discrete motor bike
Technical field
Shock mitigation system after a kind of motor bike discrete, a technical field of the genus vehicle.
Background technology
The adaptive capacity of two-wheeled motor vehicle road pavement all is eager to excel than the automobile of motor-tricycle and four-wheel, and its not only economy but also environmental protection, thus in the not good enough vast rural area of road conditions with the district, it is a kind of very desirable vehicle.Shock mitigation system independently separately before and after the motor bike of prior art has adopted.Because motor bike is manned or loading all concentrates on the trailing wheel, the rear wheel shock-absorbing system just becomes and is difficult to adapt to like this.Because obtain desirable shock-proof effect, necessarily require the bearing capacity of pay load and Shock absorber to be complementary, reach an equilibrium point, many or lacked and all can not obtain desirable effect.The heavy duty of motor bike is too big with the ratio of the weight of unloaded (cargo or passenger are down not together), and prior art rear wheel shock-absorbing system can't both can both take into account at all.Look after unloaded shock-proof effect when better, can not load-carrying.When the fully loaded shock-proof effect of treatment was better, zero load is the shock-proof effect extreme difference then.In the daily use of motor bike, the unloaded and fully loaded time respectively accounts for half the basically, seems extremely important so take into account both.
Summary of the invention
For the back shock mitigation system that makes motor bike can adapt to unloaded and heavily stressed two kinds of demands of different better; This programme is independent through the mode that flexibly connects with the part that is used for load-carrying or year passenger on the motor bike; And support by the independently Shock absorber that increases; In other words be exactly to be equivalent to be divided into two essentially independent parts to the back shock mitigation system of motor bike, weight when supporting is unloaded respectively and loading, the weight when manned.The concrete structure of this shock mitigation system is to be divided into front vehicle frame and back vehicle frame to the vehicle frame of motor bike, and back vehicle frame is movably connected on front vehicle frame or the rear wheel support, and front vehicle frame is hinged on the rear wheel support through the Shock absorber of installing separately respectively with the back vehicle frame.Here said flexible connection is that vehicle frame can be done relative motion with respect to front vehicle frame after it was meant, had certain degree of freedom but unseparated connection with respect to captive joint face speech.The connection mode that can satisfy this requirement is a lot.For example front vehicle frame, back vehicle frame and rear wheel support are hinged on that same axle is gone up, the back vehicle frame is hinged on the rear wheel support, and rear wheel support is hinged on the front vehicle frame, the back vehicle frame is hinged on the front vehicle frame, and it is first-class that rear wheel support is hinged on front vehicle frame.
The benefit of doing like this is to be equivalent to the back shock mitigation system is divided into essentially independent separately two parts, and first is original, uses when being used for zero load, and original first Shock absorber can design by the condition of zero load and choose.Second portion is independent, uses when being used for load-carrying or carrying, and increasing by second Shock absorber that gets on can design by load-carrying or year passenger's weight condition and choose for this reason.Because two parts are not captive joints, carry the shock-proof effect that how much can not influence first with load-carrying so whether second portion has.Just concerning the driver, no matter motor bike whether have carry or load-carrying what, the driver can obtain best intrinsic shock-proof effect, thereby has improved the level of comfort of motor bike greatly.

Among the figure:1 front vehicle frame, 2 back vehicle frames, 3 hinges, 4 first Shock absorbers, 5 second Shock absorbers, 6 rear wheel supports.
The specific embodiment
Example 1, want to be used on the motor bike load-carrying or carry passenger's part independent, at first will realize the flexible connection of back vehicle frame 2 and front vehicle frame 1.The mode that this example adopts is to be hinged on front vehicle frame 1, back vehicle frame 2 and rear wheel support 6 on the same hinge 3 as shown in Figure 1.Because the three is hinged on the same axle, so round hinge 3 level of freedom is arranged between the three.Front vehicle frame 1, be connected on the rear wheel support 6 through original first Shock absorber 4.Back vehicle frame 2 is connected on the rear wheel support 6 through second Shock absorber 5 that increases newly.Load on the vehicle frame 2 of back only can be added on rear wheel support 6 and the trailing wheel through second Shock absorber 5 like this.Whether its load-carrying reaches load-carrying, and what can not kept away device to original first and exert an influence, and ensure that the shock-proof effect of original first Shock absorber can not change with the load-carrying of motor bike.
The structure difference of example 2, this example and a last example is that it is hinged on the rear wheel support 6 through back vehicle frame 2, and rear wheel support 6 is hinged on the front vehicle frame 1 as shown in Figure 2.Realize the flexible connection of back vehicle frame 2 and front vehicle frame 1 with this mode.Other structure is the same with a last example, and the effect of gained is also the same basically with a last example.
Example 3, this example realize the flexible connection of back vehicle frame 2 and front vehicle frame 1 through back vehicle frame 2 the mode on the front vehicle frame 1 of being hinged on.In addition other structure is the same with a last example, and the effect of gained is also the same basically with a last example.
