Abstract
The utility model relates to a front shock absorber for three-wheel motorcycle, comprising a lever handle (1), a lower cylinder (2) and a jogger rod (3), wherein the jogger (3) is mounted in the lower cylinder (2); the lever handle (1) is provided with a spring (4). The utility model is characterized in that lower end of the lever handle (1) in the lower cylinder (2) is additionally provided with a piston (5). By equipping a piston at lower end of the lever handle, the utility model thoroughly solves the oil leakage problem in present three-wheel motorcycle shock absorbers. Besides, the antirust ability of the entire equipment is strengthened since prior electroplating iron material for lever handle and lower cylinder production is substituted with stainless steel. In addition, the prior aluminum material for lower cylinder is substituted with lower cylinder, which greatly strengthens the bearing ability thereof.
Description
Technical field
The utility model relates to a kind of vibration damper, specifically a kind of positive three-wheel front shock absorber.
Background technique
Vibration damper is the important component part of driving system, not only support car body but also play buffer function, vibration damper has variform, but its mechanism is roughly the same, promptly utilize spring, hydraulic oil and gas that vibrations are absorbed and discharge, thereby mechanical energy is converted into heat energy, reaches the purpose that makes the impact shock decay.At present, the vibration damper of installing on two-wheeled or tricycle has two kinds of front shock absorber and rear shock absorbers, and the rear shock absorber structure is relatively simple, generally be made up of damping spring and damper, elastic force is bigger, mostly is non-dismountable formula, what have has a controlling device, is used for the rigidity of Regulation spring.The structure of front shock absorber is relatively complicated, and is also bigger to the integrity influence of car body, not only cushions the vibrations of front-wheel, also plays a part to transmit steering force.Many uses of the front shock absorber of existing positive three-wheel and two-wheeled motor vehicle and so on same front shock absorber; but positive tricycle needs loading usually; so just make the force intensity that is subjected to of front shock absorber increase greatly; with regard to regular meeting the vibration damper oil leakage phenomenon takes place like this; and the support shank bar of existing vibration damper mostly is iron electrodeposition-type; end tube then is an aluminum, and tube of this end ruptures when being subjected to big external force easily, and the handle bar has been grown service time or electrodeposited coating will get rusty after impaired.
Summary of the invention
The purpose of this utility model is exactly the deficiency at existing positive three-wheel front shock absorber, provide that a kind of support strength is big, antirust ability by force and the positive three-wheel vibration damper of not easy oil leakage.
The purpose of this utility model can realize by following measure:
A kind of positive three-wheel front shock absorber comprises handle bar 1, end tube 2, push rod 3, and handle bar 1, push rod 3 are installed in the end tube 2, and spring 4 is installed in the handle bar 1, it is characterized in that also being provided with piston 5 in the bottom of handle bar 1 in end tube 2.
Described handle bar 1 and end tube 2 adopt stainless steel.
Between the slit of the opening of end tube 2 and handle bar 1, oil sealing 6 is housed.
2 in push rod 3 and end tube form trapped fuel chamber 7, in the trapped fuel chamber 7 hydraulic oil are housed.
Between the slit of the opening of end tube 2 and handle bar 1, be provided with wear-resistant sleeve 9.
Described push rod 3 usefulness bolts 10 are fixed in the end tube 2 from end tube 2 bottoms.
The utility model is provided with piston in the bottom of handle bar, fully solved the leakage of oil problem of existing positive three-wheel vibration damper, and because the material of handle bar and end tube adopts stainless steel to replace original iron plating, whole device antirust ability has been strengthened, the material of end tube replaces with stainless steel, more makes load intensity strengthen greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in the figure, a part of handle bar 1 of the present utility model is installed in end tube 2 inside, push rod 3 is seen from the side and is "T"-shaped, its "T"-shaped upward horizontal edge is a disc, this disc is in handle bar 1 inside, the vertical bars part of push rod 3 is then passed the bottom of handle bar 1 and from the bottom of end tube 2 push rod 3 is fixed on end tube 2 inside with bolt 10, is trapped fuel chamber 7 below handle bar 1 bottom, in the trapped fuel chamber 7 hydraulic oil is housed.The bottom of handle bar 1 can partly move up and down along the vertical bar of push rod 3, is provided with some vertical shape spill ports 8 on the bottom of handle bar 1, and spill port 8 tops are empty oil pocket 11, and the bottom is trapped fuel chamber 7.On top, push rod 3 upper ends spring 4 is arranged, be sealed and installed with oil sealing 6 in the slit of push rod 3 and end tube 2 openings, oil sealing 6 plays a part to prevent that hydraulic oil from overflowing.Wear-resistant sleeve 9 is arranged below oil sealing 6, also can play certain seal action.In order to prevent that the sealed hydraulic oil spill from going out, the utility model not only is provided with oil sealing 6, also is provided with piston 5 in the bottom of handle bar 1, makes whole device that hydraulic oil is had multiple-sealed effect like this, even hydraulic oil also is difficult for taking place oil leakage phenomenon under squeezing action repeatedly.
Working procedure of the present utility model is: when handle bar 1 is subjected to downward impact force, whole handle bar 1 is to pressing down, handle bar 1 continues to move downward when the hydraulic oil liquid level in the bottom end arrival trapped fuel chamber 7 of handle bar 1, because the bottom of handle bar 1 is provided with spill port 8, empty oil pocket 11 is UNICOM's state with trapped fuel chamber 7, and the hydraulic oil in the trapped fuel chamber 7 just enters in the sky oil pocket 11 in spill port 8 under the pressure effect of the bottom of handle bar 1 like this.Handle bar 1 continues to press down, and runs into up to its bottom that the bottom surface in trapped fuel chamber 7 or handle bar 1 suffered impact force disappear or offsets with the elastic force of spring 4.When the impact force that is subjected to when handle bar 1 disappeared, handle bar 1 moved up under the elastic force effect of spring 4 up to replying original state, and hydraulic oil flows back in the trapped fuel chamber 7 from empty oil pocket 11 via spill port 8 again, and a working procedure is promptly finished.
