Description
Technical field
The present invention relates to a kind of plastic casing and a kind of hydrostatic executor with this plastic casing, described plastic casing
It is encased in the closure member in described opening, wherein supersonic welding including the shell part with opening with by means of ultrasound wave in succession
Socket part is formed on the bonding land with the first cross section.
Background technology
It is known by means of ultrasonic bonding plastic components.Here, plastic components stacked on top of each other under stress by
Wave welding head of ultrasonic wave is loaded along direction of engagement, and wherein due to the ul-trasonic irradiation of wave welding head of ultrasonic wave, plastic components are at bonding land
Melted to thermoplasticity due to internal friction, and cold in bonding land in the case that plastic components are mobile along direction of engagement
But after, material fit ground connects each other.Here, welding can be overflow on bonding land is in contrast to the side of wave welding head of ultrasonic wave
Stream is discharged from bonding land, and described welding overflow can play damage effect in corresponding application.
Additionally, for example from list of references DE 10 2,010 047 800 A1, DE 10 2,010 047 801 A1, DE
Known hydrostatic executor in 102011 105 501 A1 and DE 10 2,014 201 791 A1.This hydrostatic execution utensil
There is electric drive, described electric drive makes master cylinder piston axially move.Master cylinder piston P-V gauge to master cylinder at this,
And it is contained in plastic casing.By the movement of master cylinder piston, manipulate via the hydrostatic pipeline being connected with plastic casing
Slave cylinder, described slave cylinder for example manipulates friction clutch.Here, plastic casing has at least one for stuffing pressure volume
Opening, to compensate the pressure medium being included in P-V and for being connected with hydrostatic pipeline by compensating container
Deng.One or more of described opening can constitute the ultrasonic bonding connection with closure member by means of ultrasonic welding method
Portion.
Content of the invention
The purpose of the present invention be by constitute between plastic casing and closure member improved ultrasonic bonding connection portion Lai
Advantageously improve plastic containers and hydrostatic executor.Especially, the purpose of the present invention is：It is provided with to have and less spill into week
The ultrasonic bonding connection portion of the welding overflow in collarette border.
Described purpose is by a kind of plastic casing and a kind of hydrostatic execution with electric drive and hydrostatic master cylinder
Device is realizing.Advantageous embodiment is described below.
The plastic casing being proposed preferably is made up of thermoplastic plastics.Plastic casing has shell part, described housing
Section has at least one opening, is wherein filled closure member in the case of constituting ultrasonic bonding connection portion by means of ultrasound wave
Enter at least one opening.Ultrasonic bonding connection portion is formed on the bonding land with the first cross section, wherein closure member
Composition turn up the soil with opening along the direction of engagement in ultrasonic bonding connection portion with bonding land axially spaced-apart for ultrasonic bonding connection
The transfer of the welding overflow in portion.This represents：Welding overflow is made to turn to so that described welding overflow by constituting transfer
The gap being not passed through between closure member and shell part reaches in the inside of plastic casing.In closure member and shell part or open
Gap between the inner circumference of mouth, such as annular gap, are particularly useful for compensating the component tolerance of closing thromboembolism and plastic casing.
According to an advantageous embodiment of plastic casing, transfer is formed by radial projection, described radial projection
There is the second cross section of opening and the Second bobbin diameter of closure member, described second cross section narrows with respect to the first cross section,
With respect to closure member, the first diameter at bonding land reduces described Second bobbin diameter.This represents：Between closure member and shell part
Gap move radially inwardly with regard to the axis of direction of engagement, and prevent the welding overflow at bonding land from directly axially passing through
Gap enters in the inside of plastic casing.More precisely, welding overflow radially turns in prominence.Welding overflow
The moment that can be formed at it be liquid and on the path to projection and its prominence steering during and after
Solidification is so that described welding overflow can be prevented from through gap by the size of the solid granulates being formed.
In order to accommodate welding overflow, axially can between this two diameters and side region of closure member of bonding land
It is provided with the recess of annular in closure member.Closure member can be by the seat of one's pants as moulding manufacture.Here, can not use
Instrument ground forms recess.As an alternative, recess can be constituted in the way of cutting.
Closure member can be configured to thromboembolism, and opening closed airtightly and in liquid-tight manner by described thromboembolism.In this regard, supersonic welding is in succession
Socket part is equally constituted airtightly and in liquid-tight manner.Can be configured to even in the opening that closure member is widened as an alternative or at least one
Fitting.This represents：Processing interface at closure member, such as screw thread or locking connect and/or the quick part connecting, such as with this
Closure member single type ground is constituted.
The hydrostatic executor being proposed comprises electric drive and hydrostatic master cylinder.Electric drive and master cylinder can accommodate
In common housing, such as in plastic casing.As an alternative, electric drive can have single housing, such as metal shell, wherein
Master cylinder has plastic casing, and described plastic casing is fixedly connected with the housing of electric drive.Electric drive is transported by means of by rotation
The changer actuating device of dynamic conversion linear movement linearly to drive the master cylinder piston of master cylinder, in other words, described master cylinder
Piston forward and moves back along manipulation axis.As an alternative, described electric drive overcomes the effect of energy storage device only along one
Individual direction makes master cylinder piston move, and wherein said master cylinder piston is moved back by energy storage device.Changer actuating device is simultaneously
Can act as gear.As an alternative, gear can be connected to downstream or the upstream of changer actuating device.Master cylinder
Piston changeably limits the volume of the pressure chamber of master cylinder, the pressure that described pressure chamber is e.g. formed by the plastic casing of master cylinder
Chamber so that building pressure when master cylinder piston is mobile in pressure chamber, and via the hydrostatic connecting tube being connected with pressure chamber
Road manipulates slave cylinder, and slave cylinder is for example used for manipulating friction clutch, and in other words, the slave cylinder piston of described slave cylinder is axially
Ground is mobile.Here, the plastic casing of master cylinder has at least one opening, the closure member being proposed is constituting ultrasonic bonding connection
Hermetically it is encased in described opening in the case of portion.
In order to consider the tolerance of closure member and opening, at the side section of closure member, such as it is provided with the region of side to opening
The gap of mouth.In order to avoid welding floods across and enters into pressure chamber and pollute the danger of the pressure medium existing wherein,
By welding overflow standoff at transfer, described pressure chamber keeps not thering is welding overflow by means of transfer.
Welding overflow can redirect in the recess of closure member after its deviation and remain there, for example, store there.
It should be understood that：Described purpose also by a kind of for using the transfer being proposed by the closure member being proposed
The method being encased in the opening of plastic casing is realizing.
Brief description
Embodiment according to Fig. 1 and 2 elaborates the present invention.It is shown in which：
Fig. 1 is shown in by means of run through the plastic casing with closure member before the engaging process of ultrasonic bonding one
