Rear shock damping system of separate motorcycle
Technical field
A shock mitigation system after motor bike discrete, a technical field of the genus vehicle.
Background technology
The adaptive capacity of two-wheeled motor vehicle road pavement is all eager to excel compared with 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 district, it is a kind of ideal vehicle.Shock mitigation system independently separately before and after the motor bike of prior art has adopted.Because carrying person on motorcycle or loading all concentrate on trailing wheel, 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 match, reach an equilibrium point, many or lacked and all can not obtain desirable effect.The heavy duty of motor bike is too large with the ratio of the weight of unloaded (not same under cargo or passenger), and prior art rear wheel shock-absorbing system cannot both can be taken into account at all.Look after unloaded shock-proof effect when better, can not load-carrying.When the fully loaded shock-proof effect for the treatment of is better, zero load is shock-proof effect extreme difference.In the routine use of motor bike, the unloaded and fully loaded time respectively accounts for half substantially, so take into account both, seems extremely important.
Summary of the invention
In order to make the rear shock mitigation system of motor bike can adapt to better two kinds of different requirements unloaded and heavy duty, this programme by motor bike for load-carrying or to take out objective part independent by the mode being flexibly connected, and supported by the independently Shock absorber increasing, be equivalent in other words the rear shock mitigation system of motor bike to be divided into two essentially independent parts weight when supporting is unloaded respectively and loading, weight when manned.The concrete structure of this shock mitigation system is that the vehicle frame of motor bike is divided into front vehicle frame and rear vehicle frame, and rear vehicle frame is movably connected on front vehicle frame or rear wheel support, and front vehicle frame and rear vehicle frame are hinged on rear wheel support by the Shock absorber of installing separately respectively.Here said flexible connection is with respect to being fixedly connected with face speech, and it refers to that rear vehicle frame can do relative motion with respect to front vehicle frame, has certain degree of freedom but unseparated connection.The connection mode that can meet this requirement is a lot.For example front vehicle frame, rear vehicle frame and rear wheel support are hinged on same axle, rear vehicle frame is hinged on rear wheel support, and rear wheel support is hinged in front vehicle frame, rear vehicle frame is hinged in front vehicle frame, and it is first-class that rear wheel support is hinged on front vehicle frame.
The benefit of doing is like this to be equivalent to rear shock mitigation system to be divided into essentially independent two parts separately, and first is original, during for zero load, uses, and original the first Shock absorber can and be chosen by unloaded condition design.Second portion is independent, during for load-carrying or carrying, uses, and increasing the second Shock absorber getting on can or take out objective weight condition design and choose by load-carrying for this reason.Because two parts are not fixedly connected with, so whether second portion has, carry and the how many shock-proof effects of first that can not affect of load-carrying.Namely concerning driver, no matter motor bike whether have carry or load-carrying how many, driver can obtain best intrinsic shock-proof effect, thereby has greatly improved the level of comfort of motor bike.

The specific embodiment
Example 1, want on motor bike for load-carrying or to take out objective part independent, first will realize being flexibly connected of rear vehicle frame 2 and front vehicle frame 1.The mode that this example adopts is that front vehicle frame 1, rear vehicle frame 2 and rear wheel support 6 are hinged on same hinge 3 as shown in Figure 1.Because three is hinged on same axle, so have certain degree of freedom round hinge 3 between three.Front vehicle frame 1, by original the first Shock absorber 4, be connected on rear wheel support 6.Rear vehicle frame 2 is connected on rear wheel support 6 by the second Shock absorber 5 newly increasing.Load like this on vehicle frame 2 only can be added on rear wheel support 6 and trailing wheel by the second Shock absorber 5.Its load-carrying whether and load-carrying how much can not keep away device to original first and exert an influence, ensure that the shock-proof effect of original the first Shock absorber can not change with the load-carrying of motor bike.
The structure difference of example 2, this example and a upper example is, it is hinged on rear wheel support 6 by rear vehicle frame 2, and rear wheel support 6 is hinged in front vehicle frame 1 as shown in Figure 2.By this mode, realize being flexibly connected of rear vehicle frame 2 and front vehicle frame 1.Other structure is the same with a upper example, and the effect of gained is also substantially the same with a upper example.
Example 3, this example are hinged on mode in front vehicle frame 1 by rear vehicle frame 2 and realize being flexibly connected of rear vehicle frame 2 and front vehicle frame 1.In addition other structure is the same with a upper example, and the effect of gained is also substantially the same with a upper example.
