Description
Technical field
The utility model relates to a kind of shock-proof car frame, relates in particular to a kind of motor bike shock-proof car frame that utilizes single rear shock absorber.
Background technology
Motor bike produce when driving vibration be one quite generally and very serious problem, the vibration source of motorcycle vibration mainly contains driving engine excitation and road excitation two classes.The driving engine excitation comprises cylinder-firing pressure, reciprocal inertia force and centrifugal inertia force.Cylinder-firing pressure mainly causes the vibratory response of parts such as cylinder body, and propagates to vehicle frame, so be one of reason that causes frame weaving.If the natural frequency of vehicle frame then may cause the generation of resonance effect in the scope of the rotational frequency of driving engine.In the driving engine reciprocal inertia force, the single order reciprocal inertia force plays a leading role, and it causes that whole motor bike is the vibration of fundamental frequency with the rotating speed.When motor bike travelled on uneven road surface, if wheel knocks stone, motor bike landed after may jumping up, though the vibration meeting of tire then is delivered on the vehicle frame through vibration damping, the vibration damping Frequency Response of shock absorber and the Frequency Response of vehicle frame are difficult to mate fully.This requires will consider the dynamic characteristics of frame of motorcycle and shock absorber design jointly when motor bike designs.
From the angle of vibrational energy, the size of vibration amplitude has embodied the size of energy, vibration spoke value evenly then embodied exergonic homogeneity.Vibration spoke value is even more then, and it is also minimum to the inside and outside destructiveness of system.From human body feeling to vibration, vibration amplitude, frequency, direction of vibration etc. are the principal elements of human body subjective assessment vibration, low (the most responsive frequency of human body is 4～8HZ) because human body is to the sensivity of high frequency, be difficult to feel that the interior spoke value difference of high-frequency vibration is different, so the homogeneity of high-frequency vibration spoke value is one of key factor that influences traveling comfort.
The method that solves motorcycle vibration at present and generally adopt is exactly to increase the anti-shake performance that rigidity of frame strengthens vehicle frame, but increased the weight and volume of vehicle frame, because the weight and volume of motor bike itself is less relatively, therefore gain in weight and volume can bring a lot of problems.
The utility model content
The purpose of this utility model is under the situation of the weight and volume that does not increase motorbike frame, weakens the vibration that produces when motor bike is driven significantly.
For achieving the above object, the utility model provides a kind of shock-proof car frame, comprise a tetragonal front vehicle frame, linear back vehicle frame and elastomeric element, one end on one side of described front vehicle frame flexibly connects with an end of back vehicle frame, and the other end on one side of described front vehicle frame utilizes described elastomeric element to be connected with vehicle frame middle part, back.
Described back vehicle frame is linear or broken line shape.One end of described back vehicle frame and the middle part of front vehicle frame are hinged by rotating shaft.Described elastomeric element is inflation hydra-shock absorber or polyamine fat rubber bodies.
Therefore, the utlity model has under the situation of the weight and volume that does not increase motorbike frame, weaken producing the advantage of ground vibration when motor bike is driven significantly.

The specific embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, structural representation for front vehicle frame of the present utility model, front vehicle frame 1 is a rhombus, is that the intersection point place on " rhombus " both sides is that an end points place on one side is first point of connection 11 at the middle part of front vehicle frame 1, and front vehicle frame 1 bottom i.e. another end points place on one side is second point of connection 12.As shown in Figure 2, be the structural representation of vehicle frame behind the utility model, back vehicle frame 2 is broken line shape (also can be linear), and the point of connection of front end is the 3rd point of connection 23, and the point of connection at middle part is the 4th point of connection 24.
As shown in Figure 3, be the structural representation of inflation hydra-shock absorber of the present utility model.When connecting rod 30 pressurizeds of inflation hydra-shock absorber 3 glided, fluid 32 that valve seat 31 interfaces are following and high pressure nitrogen 33 be pressurized simultaneously.Oil under pressure 32 is washed valve block 37 open by the folding hole 34 on the valve seat 31 and is entered epicoele.High pressure nitrogen 33 shrinks because of the characteristic that becomes the rigidity variable volume is arranged.When restoring stroke, valve block 37 has covered the folding hole 34 on the valve seat 31, refluxes in 32 normal open holes 39 on piston 38 of fluid, and dumping force increases greatly.And high pressure nitrogen 33 produces reverse dumping force because of fluid 32 pressure under valve seat 31 interfaces reduce to increase volume.The point of connection on inflation hydra-shock absorber 3 tops is the 5th point of connection 35, and the point of connection of bottom is the 6th point of connection 36.
As shown in Figure 4, be the structural representation of shock-proof car frame of the present utility model.In conjunction with Fig. 1 and 2, first point of connection 11 of front vehicle frame 1 is hinged with the 3rd point of connection 23 of back vehicle frame 2 by rotating shaft 4, second point of connection 12 of front vehicle frame 1 is connected with the 6th point of connection 36 of inflation hydra-shock absorber 3, the 4th point of connection 24 of back vehicle frame 2 is connected with the 5th point of connection 35 of inflation hydra-shock absorber 3, forms shock-proof car frame of the present utility model.The inflation hydra-shock absorber can be replaced by polyamine fat rubber bodies elastomeric material.Structural representation behind the utility model shock-proof car frame installation driving engine 5 as shown in Figure 5.

The vibrations that the driving engine crank motion produces when therefore, travelling can obviously be weakened.In like manner, motor bike passes to vehicle frame and driving engine because of the vibrations of jolting that Uneven road causes by the inflation hydra-shock absorber, because of it is rigid body,, the vibrations that jolt vibrations and engine piston crank motion that motor bike causes because of Uneven road produce also can obviously be weakened so in like manner can drawing the vibrations that the road surface produces by above-mentioned analysis.
Therefore, the utility model utilization inflation hydra-shock absorber or other shock-damping structure technology cooperate split type vehicle frame technology, be designed to a kind of vehicle frame that carries shock-damping structure, can obviously weaken two kinds of main factor: a that cause vibrations, the vibrations (launched machine mounting support is delivered to front vehicle frame) that the engine piston crank motion produces; B, jolt (being delivered to front vehicle frame) that cause because of Uneven road by the center rear shock absorber.These two classes vibrations are because in front vehicle frame, had only few part to be delivered to rider's buttocks and arm by " circle limit ".Greatly reduce the frequency and the amplitude of vehicle frame afterbody vertical tremor, improve the anti-shake performance of vehicle frame, make the rider obviously weaken impression vibrations.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
