Abstract
The utility model relates to an improvement to a vehicle suspension system shock damper. Two shock damping cylinders are made into double-layer structure. Oil guide holes are uniformly distributed on the wall of an inner cavity, and the outer wall of an outer cavity is provided with a nozzle tip which makes the two shock damping cylinders communicated with each other by an oil pipe. The side wall arranged at the lower part of a guide post is provided with oil guide holes, which makes the inner cavity of the guide post communicated with the outer cavity of the shock damping cylinder through the oil guide holes arranged at the wall of the inner cavity of the shock damping cylinder. The utility model has the advantages of favorable shock damping effect, equal pressure and strong balanced capacity. The utility model is suitable for used in the shock damper of a motor vehicle.
Description
The utility model relates to a kind of improvement to the vehicle suspension system vibration damper.
The vibration damper that uses is commonly a kind of single layer structure at present, a little less than fluid pressure damping stroke weak point and the fluid pressure, when vibration damper becomes two the use, left and right sides damp liquid oil can cause damping liquid pressure not wait because of the reasons such as difference of how many generations of capacity, damping force is different, thereby influence the balance of vehicle, the big or wheel power that is hit is especially obvious when strong to load, thereby influences the cruising of vehicle.
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of damping shock absorption effective, when vibration damper becomes two the use about damp liquid can produce with equal pressure and the strong pressure damping shock absorption device of balanced capacity.
The purpose of this utility model is achieved in that by damper cylinder, the directional post that in damper cylinder, moves, the bolt of fixed guide post, connecting plate, play the nut of position-limiting action on the damper cylinder, oil sealing on the nut, oil seal cover, be arranged on damper cylinder top and play the last guide sleeve that the restricted guidance post moves, the following guide sleeve of directional post lower end is set, playing the jump ring and the hydraulic oil in the damper cylinder of the motion of restricted guidance cover forms, damper cylinder is made double layer construction, be divided into inner chamber and exocoel, on internal chamber wall, evenly be furnished with oil guiding hole, have oil nozzle on the cavity outer wall outside, oil nozzle gangs up two damper cylinders by oil pipe mutually, on the lower sides of directional post, have oil guiding hole, the directional post inner chamber is communicated with the exocoel of damper cylinder by the oil guiding hole of evenly arranging on the damper cylinder internal chamber wall.
It is effective to the utlity model has damping shock absorption.Can produce with equal pressure and the strong advantage of balanced capacity, when vehicle is subjected to impacting, directional post impacts hydraulic oil downwards, because of directional post lower end area bigger than the area sum of damper cylinder internal chamber wall oil guiding hole, therefore form hydraulic damping, when impact stroke continues when descending, oil guiding hole on the damper cylinder internal chamber wall is few more, the hydraulic oil that passes through is also few more, and hydraulic damping power is big more, and the hydraulic oil in the inner chamber can enter exocoel by oil guiding hole simultaneously, can enter the inner chamber of directional post again by the oil guiding hole of directional post lower end, make the pressure of hydraulic oil in two vibration dampers identical by the oil nozzle on the outer chamber wall simultaneously, therefore damping stroke of the present utility model is long, and anti seismic efficiency is good.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, the utility model is by damper cylinder 7, the directional post 2 of motion in damper cylinder 7, the bolt 1 of fixed guide post, connecting plate 12, play the nut 5 of position-limiting action on the damper cylinder, oil sealing 4 on the nut 5, oil seal cover 3, be arranged on damper cylinder top and play the last guide sleeve 6 that the restricted guidance post moves, the following guide sleeve 8 of directional post lower end is set, playing the jump ring 9 and the hydraulic oil in the damper cylinder 10 of 8 motions of restricted guidance cover forms, damper cylinder 7 is made double layer construction, be divided into inner chamber and exocoel, on internal chamber wall, evenly be furnished with oil guiding hole, this oil guiding hole can be made into the oil guiding hole of different-diameter, by being arranged on the internal chamber wall equably down to following, have oil nozzle on the cavity outer wall outside, oil nozzle gangs up two damper cylinders by oil pipe 14 mutually, the switch 13 that on oil pipe 14, is provided with, can add or extraction hydraulic oil to this device by this switch, on the lower sides of directional post, have oil guiding hole, the directional post inner chamber is communicated with the exocoel of damper cylinder by the oil guiding hole of evenly arranging on the damper cylinder internal chamber wall.
When vehicle was subjected to impacting, directional post impacted hydraulic oil downwards, because of directional post lower end area bigger than the area sum of damper cylinder internal chamber wall oil guiding hole.Therefore form hydraulic damping, when impact stroke continues when descending, the oil guiding hole on the damper cylinder internal chamber wall more less, the hydraulic oil that passes through is also few more, and hydraulic damping power is big more.Hydraulic oil in the inner chamber can enter exocoel by oil guiding hole simultaneously, can enter the inner chamber of directional post again by the oil guiding hole of directional post lower end, make the pressure of hydraulic oil in two vibration dampers identical by the oil nozzle on the outer chamber wall simultaneously, therefore damping stroke of the present utility model is long, and anti seismic efficiency is good.When directional post impacts downwards when ending upwards backhaul, hydraulic oil oppositely flows back to along original oil circuit again, and plays the hydraulic damping effect.
