Abstract
The utility model discloses a damper for a pipeline of a hydraulic clutch system of a motor vehicle. The damper comprises a damper casing with an oil inlet and an oil outlet, an elastic body with inverted-U-shaped structural longitudinal section is hermetically pressed to fit into the damper casing by a damper cover through a damper plate with an oil hole, and the top of the elastic body is in clearance fit with the inner wall of the damper casing. The damper has the advantages of simple structure, low cost and capabilities of reducing vibration noise effectively and suppressing severe vibration generated from a clutch pipeline. The damper casing, the damper cover and a positioning rod can be made of PA66 materials, the elastic body can be made of EPDM (ethylene-propylene-diene monomer) materials, and the damper plate can be made of DC01 materials. During use, the pipeline damper is connected to the pipeline of the clutch system, vibration and impact energy are absorbed and attenuated by volume change of an inner cavity of the elastic body, and dynamic response of components is decreased.
Description
Technical field
The utility model relates to the automobile clutch system, especially relates to a kind of hydraulic pressure of motor vehicle formula clutch system pipeline damper.
Background technique
The automobile clutch control system is solenoidoperated cluthes combination and the device that separates, and it originates in clutch pedal, ends at the release bearing (or concentric wheel cylinder) in the clutch housing, is divided into mechanical pull rod control and hydraulic type control dual mode.Mechanical pull rod control artis is many, and frictional loss is large, arranges and handle relatively difficulty at automobile, seldom adopts at present.The hydraulic type operating mechanism is comprised of master cylinder, clutch release slave cylinder and pipe-line system, has that surface friction drag is little, an advantage such as arrangement convenience, joint are mild, and is not subjected to the impact of body distortion.But hydraulic system can be subject to the impact of air in master cylinder performance and the pipe-line system in use, affects the thorough separation of clutch, causes the clutch pedal vibration, causes the different sound of clutch control system, affects the run smoothness of Motor Vehicle.
Summary of the invention
It is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, hydraulic pressure of motor vehicle formula clutch system pipeline damper that can the attenuation vibration noise.
For achieving the above object, the utility model can be taked following technical proposals:
Hydraulic pressure of motor vehicle formula clutch system pipeline damper described in the utility model, it comprises the damper housing with filler opening and oil outlet, and the elastomer that the longitudinal section is inverted U-shaped is combined in the described damper housing by the damped device lid of the damper dish that offers oil-through hole sealing pressing; Described elastomeric top and damper inner walls Spielpassung.
The central position of described damper dish is fixed with positioning rod, and described positioning rod extends in the described elastomer inner chamber; This positioning rod can guarantee damper dish and elastomeric relative fixed position, guarantees passing through smoothly of hydraulic oil.
Be provided with bulge loop near on the elastomer inwall of damper dish; Can slow down oil pressure to elastomeric impact, prolong the elastomeric life-span, play good throttling action.
The utility model has the advantage of simple in structure, with low cost, but the effective attenuation vibrating noise is controlled the larger vibration that clutch pipeline produces.Damper housing, damper cover and positioning rod can adopt the PA66 material, and elastomer can select to use the EPDM material, and the damper dish can adopt the DC01 material.During use, it is serially connected on the clutch system pipeline, by the variation of elastomer cavity volume, attenuation by absorption vibration and the energy that impacts reduce the dynamic response of constituting parts.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, hydraulic pressure of motor vehicle formula clutch system pipeline damper described in the utility model, it comprises the damper housing 3 with filler opening 1 and oil outlet 2, and the elastomer 4 that the longitudinal section is inverted U-shaped covers 6 sealing pressings by the damper dish 5 damped devices that offer oil-through hole and is combined in the damper housing 3; The top of elastomer 4 and damper housing 3 inwall Spielpassung; Be fixed with positioning rod 7 in the central position of damper dish 5, positioning rod 7 extends in elastomer 4 inner chambers; Be provided with bulge loop 8 near on the elastomer inwall of damper dish 5.
The utility model connects on the pipeline between vehicular clutch master cylinder and the concentric clutch slave cylinder by the quick inserting joint, under normal circumstances, the oil pressure that clutch master cylinder provides is in the 3-55bar scope, along with hydraulic oil temperature from low to high, volume can occur elastomer 4 increases, the volume that increases can be from 0.1 cubic centimetre to 0.9 cubic centimetre, Volume Changes by elastomer 4, suppress the impact of cyclic load and impulsive load: in the normal running process, the pipeline normal heat expands, hydraulic oil is entered in the damper housing 3 by filler opening 1, flow through the gap between elastomer 4 tops and damper housing 3 inwalls, almost do not have hydraulic oil to enter elastomer 4 inner chambers from the oil-through hole of damper dish 5, almost do not have damping force this moment; When the load transition, hydraulic fluid pressure increase sharply (when generally being increased to 20bar), elastomer 4 will be activated, hydraulic oil enters the inner chamber of elastomer 4 from the oil-through hole of damper dish 5, the cavity volume of elastomer 4 is increased sharply, produce the reverse resistance identical with extraneous vibration power size, control clutch pipeline and produce larger vibration.Can measure by test, in the clutch system pipeline, behind serial connection the utility model damper, can reduce 12 microns of clutch pedal amplitudes, effectively reduce the different sound of clutch control system, guarantee the smoothness that travels.
