Description

The front damper of motorcycle of adjustable damping and soft or hard
Technical field
The utility model relates to a kind of front damper of motorcycle that can adjust damping and soft or hard.
Background technique
The damping of common front damper of motorcycle and pre-pressure of the spring are just determined at the beginning of design, damping force is the size decision by damping hole, the soft or hard of vibration damper is the rigidity decision of spring own, determine damping characteristic and spring rate by testing, damping characteristic and spring rate directly have influence on travelling comfort, because damping hole, spring rate, length etc. immobilize, its damping characteristic and spring rate, pre-pressure of the spring is also just determined, because vehicle difference, passenger's difference, be difficult to satisfy different automobile types and different requirement of client, therefore, the adaptability of original vibration damper is very poor, and prior art can be carried out the adjusting of damping force and pre-pressure of the spring respectively in addition, and applying to vehicle such as go-anywhere vehicle substantially, common knight's car is utilization not.Both combinations be yet there are no report to the device of damping force and pre-pressure of the spring adjusting simultaneously.
Summary of the invention
For solving above technical problem, the utility model provides the device that a kind of while can regulate the damping and the soft or hard of front damper of motorcycle.It can easily regulate damping force and pre-pressure of the spring, so that make the adaptability of vibration damper stronger, more meets different requirement of client.
The front damper of motorcycle of a kind of adjustable damping and soft or hard, it is characterized in that this front damper of motorcycle comprises adjusting screw rod 1, nut 2, push rod 3, box type piston bar 4, O type circle 5, valve core spring 6, damping spring 7, hollow screw 8, piston assembly 9, valve block 10, spring sheet 11, piston seat 12, main spring 13, handle bar 17, floating piston 18, O type circle 19, adjusting screw 20, bolt 21 silently, seal ring 23, back-up ring 22 and hole are with back-up ring 24;
Adjusting screw rod 1 withstands push rod 3, push rod 3 places box type piston bar 4 endoporus, O type circle 5 and valve core spring 6 are placed on the push rod 3, push rod 3 conical surfaces are over against the taper hole face of hollow screw 8, the damping hole of box type piston bar 4 is between hollow screw 8 and push rod 3, and damping spring 7 is through on the box type piston bar 4; Main spring 13 withstands on the floating piston 18, and O type circle 19 is placed on the floating piston 18, and the other end of floating piston 18 withstands on the adjusting screw 20, and main spring 13, floating piston 18, O type circle 19, adjusting screw 20 all place handle bar 17 endoporus.
Above-mentioned silently bolt 21 is threaded onto handle bar 17 tapped holes, and adjusting screw 20 is threaded onto silently bolt 21 tapped holes.
Above-mentioned valve block 10, spring sheet 11 and piston seat 12 are loaded on piston assembly 9 inboards, are screwed into box type piston bar 4 heads with hollow screw 8, and seal ring 23 and back-up ring 22 are fitted in the handle bar 17, and seal ring 23 is blocked with back-up ring 24 in the hole.
