Abstract
The utility model discloses a double security bidirectional shock absorber, which comprises a connecting unit, a shock absorbing cylinder, a guiding sleeve, an oil seal, a flattened wire, a dustproof seal, an upper spring socket, a lower spring socket, a nut, an oil plug and a shock absorbing pillar. Wherein, bifarious guiding sleeve structures are arranged between the shock absorbing pillar, the shock absorbing cylinder and the shock absorbing pillar in series. The guiding sleeves are limited by an elastic clamping ring arranged on the shock absorbing pillar. The spring is arranged between the upper sleeve and the guiding sleeve. The springs are also arranged between the upper sleeves and guiding sleeves, and between the shocking absorbing cylinder and the end face of the shock absorbing pillar. The two springs and the main spring between the upper spring socket and the lower spring socket can jointly complete the function of bidirectional shock absorption. The two guiding sleeves connected in series with the shock absorbing pillar can display the function of double security, increase the guiding length and improve the stability on the work of the shock absorber. The utility model is suitable for an agricultural tricycle, a motorbike and a tricycle motorbike.
Description
Technical field
The utility model relates to a kind of shockproof, dual fail-safe double-acting shock absorber that damping is used.
Background technique
Be provided with vibration damper between the front-wheel wheel shaft of agricultural tricycle, motorcycle and motor tricycle and handlebar, the vibrations that produce when reducing on rough road walking.Now form by main part such as damper cylinder, shock structure, guide sleeve, collar, spring, spring seat and nut with vibration damper; Guide sleeve is loaded on the shock structure, and its outer end is spacing with elastic collar by axle; When the car walking was on ups and downs road, by the compressive strain damping of spring, shock structure moved up and down in damper cylinder simultaneously; But, influence the proper functioning of vibration damper because axle gets loose easily with elastic collar.
The model utility content
The purpose of this utility model is to provide a kind of dual fail-safe double-acting shock absorber for overcoming above-mentioned deficiency, is positioned at the inside and outside spring energy twocouese damping of damper cylinder, and two groups of guide sleeves that are connected on the shock structure are compared reliable operation with used vibration damper.
The purpose of this utility model is achieved in that
A kind of dual fail-safe double-acting shock absorber, comprise link, damper cylinder, spring, guide sleeve, oil sealing, silk pressing, dust sealing, upper spring seat, lower spring cup, nut, plug cock and shock structure, between shock structure and damper cylinder, be provided with double guide sleeve structure, two guide sleeve structures are connected on the shock structure, guide sleeve is spacing by the elastic collar that is loaded on the shock structure, is provided with spring between last cover and guide sleeve.
Further, the described restricted guidance elastic collar that overlaps axial position also can be to be provided with the guide sleeve axial limiting reached on shock structure increases the shoulder of effect with one heart.
Going up between cover and the guide sleeve of dual fail-safe double-acting shock absorber is provided with spring, also is provided with spring between the end face of damper cylinder and shock structure, and the main spring between this two spring and upper and lower spring seat can be realized two-way damping; Two groups of guide sleeves of contacting on the shock structure not only play the length that the double insurance effect has also strengthened guiding, have increased the stationarity of vibration damper work.
Description of drawings
Fig. 1 is the utility model schematic representation.
Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
The dual fail-safe double-acting shock absorber by link 1, damper cylinder 2, spring 3, elastic collar 4, lower spring cup 5, down guide sleeve 6, go up guide sleeve 7, spring 8, on overlap 9, main spring 10, combination oil seal 11, dust sealing 12, silk pressing 13, upper spring seat 14, nut 15, shock structure 16, oil stifled 17 and separation sleeve 18 form.Referring to Fig. 1.Be provided with shoulder hole in the damper cylinder, two guide sleeves are housed in the aperture of shoulder hole, the external diameter of guide sleeve and the aperture of shoulder hole match, and the hole and the shock structure of guide sleeve match; The combined seal be made up of separation sleeve and two single oil sealings or the unitized seal of lengthening are equipped with in the outer end of last cover, and guaranteeing not can leakage of oil; The outer end of combination oil seal dress silk pressing, silk pressing and damper cylinder are equipped with dust sealing 12 and enter with the dust outside preventing for being threaded in the silk pressing.Be welded with lower spring cup on the damper cylinder, the main spring that plays cushioning effect is loaded between the upper and lower spring seat, and by the degree of tightness that is loaded on the nut Regulation spring on the shock structure.Shock structure is the hollow-core construction with hole, and this hole is made as through hole; It is stifled that oil is housed in the outer end of through hole; Its effect is to load onto oil to block up after giving the vibration damper oiling, and oil sealing is closed.Hole on the link of vibration damper lower end is loaded on the wheel shaft of tricycle front-wheel, and its shock structure is loaded in the connecting plate hole on the handlebar and is fixing with nut 15.Owing to be provided with two guide sleeves in the damper cylinder of the present utility model, it is longer with the axial contact length of damper cylinder, and steering capability is good, is difficult for having produced wrapping phenomenon, has prolonged the life-span of vibration damper greatly.Between the end face of shock structure and damper cylinder, be provided with spring 3, last cover, on be provided with spring 8 between guide sleeve, aforementioned two springs can be realized two-way damping; The upper and lower guide sleeve that is loaded on the shock structure is respectively spacing by elastic collar, and after an elastic collar lost efficacy, another elastic collar still worked, and works on, and plays a part double insurance, has improved the reliability of work.
Claims (2)
1. dual fail-safe double-acting shock absorber, comprise link, damper cylinder, spring, guide sleeve, oil sealing, silk pressing, dust sealing, upper spring seat, lower spring cup, nut, plug cock and shock structure, it is characterized in that: between shock structure and damper cylinder, be provided with double guide sleeve structure, two guide sleeve structures are connected on the shock structure, guide sleeve is spacing by the elastic collar that is loaded on the shock structure, is provided with spring between last cover and guide sleeve.
2. dual fail-safe double-acting shock absorber as claimed in claim 1 is characterized in that: the elastic collar that described restricted guidance overlaps axial position also can be the shoulder of establishing guide sleeve axial limiting and the concentric effect of increase on shock structure.
