Abstract
The invention provides a damp self-regulating front damper of a motorcycle and a manufacturing method thereof in order to solve the problems that the damping force of a front damper of a motorcycle can not be automatically regulated with the variation of the vibration force acting on the motorcycle in the prior art, the damping effect is limited and the like. In the damp self-regulating front damper of a motorcycle, a locating pipe has no throttling orifice, the throttling orifice comprises a diameter-variable structure, that is, the outer diameter of the locating pipe is gradually reduced from the upper end of an oil through hole to the upper part of the locating pipe, so that the size of the throttling orifice composed of the locating pipe and a lower piston of a branch pipe assembly is variable in the axial direction of the locating pipe. The damping force of the damp self-regulating front damper of a motorcycle can be automatically regulated with the vibration degree of the damping spring. The higher the vibration degree is, the larger the damping force is; and the lower the vibration degree is, the smaller the damping force is. Besides, the damping force can be continuously variable. The damp self-regulating front damper of a motorcycle effectively enhances the damping effect of the front motorcycle damper and improves the driving comfort and safety of the motorcycle.

Technical field
The present invention relates to a kind of motorcycle vibration absorber damper and preparation method thereof, specially refer to a kind of motorcycle and become damping front shock absorber damper and preparation method thereof automatically.
Background technique
Along with motorcycle technology development, the travelling comfort that motorcycle is driven, the requirement of Security are more and more higher.At present, most of motorcycles have all disposed forward and backward vibration damper, to reduce vibrations that Uneven road the causes influence to motorcycle and driver and passenger.The mode that the vibration damper of prior art motorcycle mostly adopts spring to combine with hydraulic damping, the vibration energy in absorption and the consumption motorcycle driving process is to reduce the influence of vibrations to motorcycle and driver and passenger.The basic functional principle of prior art front damper of motorcycle is: in the motorcycle driving process, if when running into the ground of projection, motorcycle front-wheel compressing damping spring shrinks, behind the ground of crossing projection, spring resets again, the vibration energy reciprocal according to this, that absorption and consumption Uneven road bring.Usually, damping spring has bigger compression strength, after damping spring is compressed, can not allow it freely reset, otherwise resetting suddenly of damping spring will cause the secondary vibrations.For slowing down the reset speed of damping spring, be provided with damping mechanism in the front damper of motorcycle of prior art.In the compressed while of the damping spring of front damper of motorcycle, also be injected into hydraulic oil in the hydraulic damping chamber, when damping spring resets, hydraulic oil in the hydraulic damping chamber refluxes with specific speed, make damping spring to reset immediately, but reset along with the backflow of hydraulic oil in the hydraulic damping chamber.The effect of this decay spring vibration of vibration damper is commonly called damping, and and slows down the strength that damping spring resets and be called as damping force.
The back-flow velocity of the hydraulic oil in the prior art front damper of motorcycle hydraulic damping chamber is fixed, and promptly no matter damping spring is subjected to great pressure, what has been compressed, and the reset speed of damping spring is all fixed.Need to prove that the back-flow velocity of described hydraulic oil is not meant the speed that hydraulic oil flows, and is meant that hydraulic oil flows back to the speed of oil cylinder from the hydraulic damping chamber.And the jarring forces that motorcycle is run in the actual travel process is ever-changing, and the compressed degree of damping spring also has nothing in common with each other.In the compressed degree of damping spring hour, should allow damping spring reset to recover the situation of smooth-ride as early as possible with fast speeds; When the compressed degree of damping spring is big, should allow damping spring reset to avoid causing the secondary vibrations with slower speed.Obviously, the prior art front damper of motorcycle can not satisfy above-mentioned requirements, and the damping force of vibration damper can not be regulated automatically with the jarring forces that motorcycle is subjected to, and its damping effect is limited, directly has influence on travelling comfort and Security that motorcycle is driven.
Summary of the invention
Can not regulate automatically with the jarring forces that motorcycle is subjected to for solving the damping force that the prior art front damper of motorcycle exists, problem such as damping effect is limited, the present invention proposes a kind of motorcycle and becomes damping front shock absorber damper and preparation method thereof automatically.Motorcycle of the present invention becomes damping front shock absorber damper automatically throttle orifice is not set on positioning pipe, adopt variable-diameter structure to form throttle orifice, be that the positioning pipe external diameter diminishes until positioning pipe top gradually from the oil through upper end, make of the axial variation of the throttle orifice size of circle composition in positioning pipe cylindrical and the breeches pipe assembly lower piston along positioning pipe.
It is that the positioning pipe external diameter is diminished until positioning pipe top gradually from the oil through upper end that motorcycle of the present invention becomes damping front shock absorber damper making method automatically, makes the axial variation of the throttle orifice size of circle composition in positioning pipe cylindrical and the breeches pipe assembly lower piston along positioning pipe.
The useful technique effect that motorcycle of the present invention becomes damping front shock absorber damper automatically is: the damping force of vibration damper can be regulated automatically along with the degree of damping spring vibration, and extent of vibration is big more, and damping force is also just big more; Otherwise, then more little, and be continuous variation.Motorcycle of the present invention becomes the damping that damping front shock absorber damper has effectively improved front damper of motorcycle automatically, has improved the travelling comfort and the Security of motorcycle driving.

Accompanying drawing 1 is the generalized section of prior art front damper of motorcycle;
Accompanying drawing 2 is generalized sections that motorcycle of the present invention becomes damping front shock absorber damper automatically;
Accompanying drawing 3 is that motorcycle of the present invention becomes the generalized section that damping front shock absorber damper positioning pipe external diameter changes vertically automatically;
Accompanying drawing 4 is cross-sectional schematic that motorcycle of the present invention becomes damping front shock absorber damper positioning pipe and breeches pipe assembly lower piston composition throttle orifice automatically.
Below in conjunction with the drawings and specific embodiments motorcycle of the present invention being become damping front shock absorber damper and preparation method thereof automatically is further described.
Embodiment
Accompanying drawing 2 is generalized sections that motorcycle of the present invention becomes damping front shock absorber damper automatically, among the figure, and the 1st, end tube, the 2nd, breeches pipe assembly, the 3rd, damping spring, the 4th, positioning pipe, the 5th, one-way valve, the 7th, oil through, the 8th, the lower piston of breeches pipe assembly, the 9th, the positioning pipe external diameter is changing unit vertically.As seen from the figure, motorcycle of the present invention becomes damping front shock absorber damper automatically and compares with the prior art front damper of motorcycle, throttle orifice 6 is not set on positioning pipe 4, and adopt variable-diameter structure to form throttle orifice, be that the positioning pipe external diameter diminishes until positioning pipe top gradually from the oil through upper end, make of the axial variation of the throttle orifice size of positioning pipe and breeches pipe assembly lower piston composition along positioning pipe.
Accompanying drawing 3 is that motorcycle of the present invention becomes the generalized section that damping front shock absorber damper positioning pipe external diameter changes vertically automatically, among the figure, and the 4th, positioning pipe, the 9th, the positioning pipe external diameter is changing unit vertically.As seen from the figure, the motorcycle of the present invention positioning pipe external diameter that becomes damping front shock absorber damper automatically diminishes until positioning pipe top gradually from the oil through upper end.Accompanying drawing 4 is cross-sectional schematic that motorcycle of the present invention becomes damping front shock absorber damper positioning pipe and breeches pipe assembly lower piston composition throttle orifice automatically, the 4th, and positioning pipe, the 8th, the lower piston of breeches pipe assembly, the 9th, the positioning pipe external diameter is changing unit vertically.As seen from the figure, throttle orifice that motorcycle of the present invention becomes damping front shock absorber damper automatically is actually by positioning pipe 4 and breeches pipe assembly lower piston 8 to be formed, and promptly is made up of the gap between the interior circle of the cylindrical of positioning pipe and breeches pipe assembly lower piston.Because the external diameter of positioning pipe is provided with changing unit 9 vertically, and this variation is to diminish gradually until positioning pipe top from the oil through upper end, therefore, the size that motorcycle of the present invention becomes the throttle orifice of damping front shock absorber damper automatically is along axially the gradually changing of positioning pipe, and becomes big from bottom to top gradually.When the compressed degree of damping spring bigger, when breeches pipe assembly 2 drive lower pistons 8 move to the lower position of positioning pipe 4, less by the throttle orifice that positioning pipe 4 and breeches pipe assembly lower piston 8 are formed, when damping spring resets, the back-flow velocity of hydraulic oil is less in the hydraulic damping chamber, also be that damping force is bigger, damping spring will reset slowly.Otherwise, when the compressed degree of damping spring less, when breeches pipe assembly 2 will drive lower piston 8 and move to positioning pipe 4 tops, the throttle orifice of being made up of positioning pipe 4 and breeches pipe assembly lower piston 8 is bigger, when damping spring resets, the back-flow velocity of hydraulic oil is bigger in the hydraulic damping chamber, also is that damping force is less, and damping spring will reset faster.When preventing that breeches pipe assembly lower piston 8 from moving to positioning pipe 4 tops because trembling of may causing of the unexpected sealing of throttle orifice (becoming flow suddenly from peak rate of flow is zero) or shake, be provided with the positioning pipe external diameter at the minimum place of positioning pipe external diameter (being the throttle orifice biggest place) and become big excessive section gradually, avoided issuable and trembled or shake, guaranteed the smooth-ride of motorcycle.Because the process of the axial variation of positioning pipe external diameter is continuous, therefore, the size variation of throttle orifice also is continuous, and the variation of damping force also will be continuous.By accompanying drawing 2 also as can be known, the axial motion of breeches pipe assembly lower piston is led by circle in the cylindrical of breeches pipe assembly and the end tube, the axial variation of positioning pipe outside diameter can not influence the axial motion of breeches pipe assembly lower piston, the interior circle of breeches pipe assembly lower piston and the gap between the positioning pipe cylindrical can not cause the infringement of breeches pipe assembly lower piston to the positioning pipe cylindrical, do not wave or rock in the time of can not causing the axial motion of breeches pipe assembly lower piston yet.
Making motorcycle of the present invention becomes damping front shock absorber damper automatically and does not need to increase special equipment, the common machine working machine tool, all can as equipment such as lathe, external cylindrical grinding machines, its basic making method is that the positioning pipe external diameter is diminished until positioning pipe top gradually from the oil through upper end, makes the axial variation of the throttle orifice size of circle composition in positioning pipe cylindrical and the breeches pipe assembly lower piston along positioning pipe.
The damping force that motorcycle of the present invention becomes damping front shock absorber damper automatically can change automatically along with the compressed degree of damping spring, and compression degree is big more, and damping force is also just big more; Otherwise, then more little; And be to change continuously.Motorcycle of the present invention becomes the damping that damping front shock absorber damper has effectively improved front damper of motorcycle automatically, has improved the travelling comfort and the Security of motorcycle driving.
