Description
Technical field
The present invention relates to a kind of pressure-regulating valve that has integrated damper element in hydraulic part, particularly to the pressure-regulating valve of the Electromagnetically activatable in automotive field, used.
Background technology
A kind of device that is used for being adjusted in the pressure of hydraulic circuit is disclosed by DE 100 24 700 A1.Be provided with electronic controlled pressure-regulating valve, it has the magnetic portion that has electronic controlled coil, movingly Dao Xiang armature and the hydraulic part that is connected with magnetic portion.In hydraulic part inside, can connect by the pressure medium that the closure elements that the armature of magnetic portion promotes is controlled between at least one service aisle and the return flow line.Be provided with the device that is used for decaying in the pressure surge of service aisle, wherein this device is the integrated ingredient of pressure-regulating valve and interacts with its housing and to surround the pressure chamber with variable volume that at least one periphery is arranged.
According to the solution of DE 100 24 700 A1, at least one wall of this pressure chamber is made of the diaphragm of elastically deformable.This diaphragm is molded on the seal element of pressure-regulating valve integratedly.
The assurance of the function of the pressure-regulating valve of variable valve, particularly in question type and fatigue strength, the dynamic perfromance that requires in view of the high dynamic when the hydraulic system that will control enough stable about all working state.The damping that this causes the medium that is used to transmit pressure to get well.Verified in view of recyclability and lag behind inevitably that to amplify be problematic by the damping of using mechanical friction.The damping that produces with the electromagnetism approach is because very little hypomotility is enough effective.Under the situation of automatic transmission, based on pressure transmission medium, the particularly existence of transmission oil and at first suitable viscosity damping, in view of dynamic perfromance has shortcoming, reason is the dependence of its viscosity to pressure transmission medium.Flexible drawing pressed and the use of flexural spring has undesirable influence on the pressure/stream ratio of pressure-regulating valve.Being incorporated on the only limited installing space that provides and on the productibility of costliness of damping based on the flow state of eddy current failed.If in pressure-regulating valve, realize the volume of hydraulic pressure, it have or do not have rigidly in variable valve self and around variable valve as damper element, this needs very big installing space and shows as the parts of wanting consistent in view of the use of the pressure-regulating valve of such hydraulic shock-absorption.
Summary of the invention
The solution of the present invention of will giving chapter and verse below, i.e. the member of integrated compression elasticity in the hydraulic part of the pressure governor of Electromagnetically activatable, it preferably relates to the elastic body drip molding, with the hydraulic volume in the hydraulic part that influences pressure governor targetedly.The hydraulic shock-absorption element of decision design elastomer-forming drip molding can be constructed with pressure-regulating valve, wherein only alternatively has following possibility, and promptly the damper element that proposes according to the present invention uses as the member that separates.Preferred this damper element with the form of elastic body drip molding near near regulating element direct use in controlled plant.
Advise that according to the present invention the shock absorbing characteristics of preferably making the damper element of elastic body drip molding (dimension is logical) does not rely on the viscosity of the pressure medium of transmission.The function of the pressure-regulating valve of Electromagnetically activatable constructed according to the invention in addition every type the dirt of pressure medium relatively all is insensitive.If the pressure-regulating valve of suggestion uses on automatic transmission in order to gear shift according to the present invention, then guarantee it to what during the working time of automatic transmission, produce, the insensitivity of the dirt that in transmission oil, gathers in road vehicle application.
Because the damper element of suggestion is preferably produced as the elastic body drip molding according to the present invention, it can wherein will realize the easy associativity in the hydraulic pressure flange of damper element on the pressure-regulating valve of for example Electromagnetically activatable especially in view of shape and big or small with big degree of freedom manufacturing.Hydraulic volume and consequent shock absorbing characteristics can mate the zone of packing into of the pressure-regulating valve that improves according to the present invention especially simply, because the shock absorbing characteristics of damper element is by its composition of air and its moulding, its dynamic perfromance is determined in material and the connection on the hydraulic part of pressure-regulating valve.
Can be preferably has high elasticity for the dynamic of the pressure-regulating valve that influences Electromagnetically activatable, the pressure pulsation in the hydraulic pressure transfer passage of can obviously decaying thus as the damper element of elastic body drip molding production.This damper element is preferably made the FKM elastic body drip molding (dimension logical) of foaming and thus can be with multiple shape and big small-scale production.The material of using is because high medium and temperature tolerance and outstanding.The suggestion according to the present invention, the fatigue strength that preferably uses the damper element on the hydraulic pressure flange are on the one hand by its structure assurance by the trellis of the sealing of the shell encirclement of media-resistant.The damper element of suggestion has the composition of air until 30% according to the present invention, and wherein composition of air can fluctuate about 5% to 10%.Its shock absorbing characteristics of composition of air definition of the damper element of advising according to the present invention also can very mate simply to the different hydraulic environment that has wherein used the damper element of advising according to the present invention.
Except in motor vehicle, using the use on the pressure-regulating valve that on automatic transmission, is used for gear shift, this damper element can also be because its high medium and the temperature tolerance pressure transmission medium that offers other, brake fluid for example, hydraulic fluid, fuel, water or analog.The use of the damper element of suggestion on the parts different with the pressure-regulating valve of in question Electromagnetically activatable here also can be considered fully according to the present invention in addition.
