The invention also relates to a clutch system with the actuator.
Description
Technical Field
The present invention relates to an actuator for actuating a motor vehicle clutch, i.e. a motor vehicle clutch, for example a passenger car, a truck, a bus or other commercial vehicles, having an electric servomotor and a wire system electrically connected to the servomotor. The invention also relates to a clutch system for a motor vehicle drive train, comprising a clutch and the actuator.
Background
Actuators for clutch actuation are well known in the art. In this respect, DE 10 2015 206 786 A1, for example, discloses an actuator, called an actuator system, in particular for actuating a clutch system or a brake system of a motor vehicle. However, details for forming the wire system connected to the servomotor are not disclosed in this respect.
In the known actuators, it has also proven to be disadvantageous that the respective connection areas of the cables of the wire system on the servo motor are often not adequately sealed. However, it should be ensured that no gap occurs between the cable and the sheath when the inserted sheath of the connection region is manufactured, through which gap liquid can penetrate into the connection region during operation, thereby promoting corrosion of the connection region. The connection region is thus reliably protected against liquids, such as spray water, oil, lubricants, fuels and other acids, around the servomotor during as long a period of operation as possible. It should also be ensured that the components surrounding these connection areas are as low flammable as possible.
The prior art is also known from EP 2 245 705 A1. A plug connector element having a sealing mechanism in a cable connection region is disclosed. However, the embodiments herein converted are relatively unsuitable for the environmental conditions prevailing in the automotive field, wherein significantly higher demands are placed on corrosion resistance and defined installation space conditions.
Disclosure of Invention
The object of the present invention is therefore to eliminate the disadvantages known from the prior art and in particular to provide an actuator which on the one hand is reliably protected against corrosion damage and on the other hand has a configuration which is as compact as possible.
This object is achieved by the actuator according to the invention for actuating a motor vehicle clutch, wherein the actuator according to the invention for actuating a motor vehicle clutch has an electric servomotor and a wire system electrically coupled to the servomotor, wherein at least one wire of the wire system further comprises an insulating housing made of plastic material and a stripped conductor section connected to the servomotor (in the connection region), and wherein the wire is surrounded not only in the region of the conductor section but also in a longitudinal section of the insulating housing next to the conductor section by a jacket which together serves as a seal, which is formed from a plastic material which is thermoset or thermoplastic and which is different from the plastic material of the insulating housing, and wherein a sleeve is placed in a form-fitting and/or force-fitting manner on a longitudinal section of the insulating housing such that the sleeve forms at least partially a wave-shaped outer contour, which is in direct contact with the jacket.
With such a jacket according to the invention of the respective connection region of the cable on the servomotor side, it is possible to construct the sealing distance along the cable ensured by the jacket as short as possible. By means of the additional sleeve, an element is provided which, on the one hand, secures the sleeve as strongly as possible and, on the other hand, prevents undesirable gaps and thus leaks from forming during the production process when the cable is encapsulated by means of encapsulation. In this way, a particularly stable sealing of the cable connection region is achieved.
Other advantageous embodiments are described in more detail below.
If the insulating housing is made of a thermoplastic material, the insulating housing is particularly stable with respect to the usual working media of motor vehicles.
In this respect, it is particularly advantageous if the insulating sheath consists of a polyolefin.
The device according to the invention is particularly effective to implement if the sleeve consists of a thermosetting plastic material.
The sleeve is more firmly realized if the sleeve is composed of a nonferrous metal alloy, for example a nonferrous metal alloy containing copper, for example brass, bronze or the like.
It is also advantageous if the sleeve is pushed over its entire length onto the longitudinal section of the insulating housing. Thus, the sleeve does not protrude beyond the insulating housing along the cable. Thereby, the sleeve serves only as a connecting element for fixing the sheath to the cable/insulating housing. Thereby achieving a reliable seal.
It is also advantageous for the sleeve to be fastened to the insulating housing by means of a crimped connection.
The sheath is particularly firmly connected further to the cable if the sleeve is contacted/surrounded by the sheath over its entire length. Alternatively, it is also advantageous if the sleeve protrudes from the sheath.
In this context, it is also advantageous if the sleeve forms an end-side flange which protrudes from the insulating housing in the radial direction, wherein the flange is in direct contact with the jacket on its sides facing away from one another in the axial direction, i.e. as seen in the longitudinal direction of the cable. The fixing of the sheath to the sleeve and thus to the cable is thereby further reinforced.
Furthermore, it is expedient if a plurality of wave parts of the sleeve are connected to the flange in the axial direction of the cable, wherein the jacket bears against the sleeve over the entire longitudinal extension of the wave parts. Thereby further improving the retention of the wrap on the sleeve side.
Furthermore, it is advantageous if the plurality of cables each surrounded by the sleeve are surrounded together by a (same) jacket not only on their conductor sections but also on the longitudinal sections of their insulating housing directly adjacent to the conductor sections. Thereby, the manufacturing cost is further reduced.
With regard to the sheath, it is further preferred that it is formed directly as an injection-molded encapsulation/casting, whereby the sheath is applied directly around the cable while still in the liquid state during the forming process (urformvorg). After hardening of the material constituting the sheath, an effective sealing of the respective connection region of the cable is achieved.
Furthermore, according to at least one of the above embodiments, the invention relates to a clutch system for a drive train of a motor vehicle, having a clutch and an actuator according to the invention acting on the clutch in an adjustable manner.
In other words, a waterproof injection-molded encapsulation or casting of the transition (connection region) of the line (cable) in the thermoset or thermoplastic component (jacket) is thus achieved. Each wire has a sheath (insulating housing) which is crimped with a metal sleeve (sleeve), respectively. All wires are then preferably enclosed/cast together in a thermosetting plastic (jacket). The sleeve has a labyrinth type (undulating outer contour) or a corresponding profiling of this function. In addition, attention is paid to the materials used, for example thermosetting injection-molded packages (jackets). The load capacity and the length of the sealing distance can thus be effectively extended, since by selecting the materials (polyolefin for the wire jacket (insulating housing) and thermosetting plastic for the injection-molded encapsulation (jacket)) a particularly good connection is achieved also in view of the elevated temperatures at the time of manufacture. The material of the sleeve is preferably a copper alloy, so that the sleeve reliably avoids the formation of a gap between the insulating housing and the jacket during the manufacturing process. In principle, a sealing mechanism for cables (wires) with multiple crimped sleeves is therefore proposed.

Detailed Description
These figures are merely schematic and are only intended to provide an understanding of the present invention. Like elements have like reference numerals.
The actuator 1 according to the invention is in principle an electric actuator 1 for actuating a clutch of a motor vehicle powertrain. The actuator 1 is thus a component of the clutch system during its operation and acts in a regulated manner on a clutch of the clutch system, for example a friction clutch.
The actuator 1 typically has an electric servomotor 2 (also referred to as an electric motor). The servomotor 2 in turn has a stator 14 and a rotor 13 rotatable relative to the stator 14. The stator 14 is accommodated in a housing 15 of the actuator 1. The rotor 13 is arranged radially outside (with respect to its axis of rotation) the stator 14. By means of the transmission 16, the rotational movement of the rotor 13 is converted in a typical manner into an axial adjusting movement on the release bearing 17 side when the servomotor 2 is activated, in order to disengage the clutch. In this case, it should be noted that the actuator 1 is constructed in its other construction according to the actuator system disclosed in DE 10 2015 206 786 A1. The implementation details described in additional detail in relation to the actuator system by means of DE 10 2015 206 786 A1 are therefore applicable to the actuator 1 according to the invention integrated therein.
In addition to the servomotor 2, the actuator 1 also has a wire system 3, which can be seen in fig. 1. The wire system 3 has a plurality of wires 4a to 4d (also called current wires) extending from the plug 12 towards the servomotor 2. Three of these cables, namely, the first cable 4a, the second cable 4b and the third cable 4c, are connected to the servomotor 2 during operation for controlling the servomotor 2. For this purpose, it is shown in detail in fig. 5 how the corresponding connection areas 22 of the first to third cables 4a to 4c on the side of the plurality of contacts 18a to 18c of the servomotor 2 are formed. The sheath 8, which is described in more detail below, is omitted in fig. 5. The first to third cables 4a to 4c are each constructed in the same manner and are connected to one of the contacts 18a, 18b or 18c, so that only the construction and connection of the first cable 4a on the first contact 18a will be described below for the sake of brevity to represent the construction and connection of the other (second and third) cables 4b,4c at the (second and third) contacts 18b,18 c.
The first cable 4a is connected to the first contact 18 a. The first cable 4a is formed as a single-core cable. The first cable 4a does not have its insulating housing 5 at one end/is stripped, wherein the end of the stripped/exposed conductor 19 of the first cable 4a is hereinafter referred to as conductor section 6. The conductor section 6 is directly connected/fixed to the first contact 18a to form a connection region 22. The insulating housing 5 starts after the conductor section 6 and extends continuously to the plug 12 (fig. 3), as seen along the cable 4a from the connection region 22. The insulating housing 5 is in this embodiment made of polyolefin.
As can also be seen in detail in fig. 4 and 5 and in general in fig. 2, the sleeve 9 is fixed to the insulating housing 5 in a form-fitting and force-fitting manner. Sleeve 9 is composed of a crimpable metal, i.e. a crimpable nonferrous metal alloy. The sleeve 9 is designed as a buckling sleeve and is thus fixed to the insulating housing 5 by means of a crimped connection from the radially outer part (seen with respect to the longitudinal extension of the first cable 4 a). As can be seen in the longitudinal section of the sleeve 9 according to fig. 4, the sleeve 9 has a wavy outer contour 10 due to the crimping. The crimping is implemented as a multiple crimping such that the outer contour 10 of the sleeve 9 has a plurality of wave-shaped portions. In general, four valleys 20 and three peaks 21 are formed. The sleeve 9 is thereby crimped and is pressed onto the insulating housing 5 in the radial direction continuously from the outside by plastic deformation on account of the crimping, so that the insulating housing 5 is compressed in the radial direction by the sleeve 9 by a certain amount. The crimping is furthermore carried out in such a way that the sleeve 9 forms, on its end region facing the conductor section 6, a flange 11 protruding radially outwards from the insulating housing 5. According to a further embodiment, such a flange 11 is also formed in principle on the end region of the sleeve 9 opposite the conductor section 6.
It is also known from fig. 4 that the sleeve 9 is selected and positioned in its length such that it is arranged only on the longitudinal section 7 of the insulating housing 5. The sleeve 9 thus ends towards the conductor section 6 before the end of the insulating housing 5 and does not protrude beyond the insulating housing 5 in the axial direction as seen along the first cable 4 a.
As shown in fig. 2 to 4, a sheath 8 is provided around the first cable 4 a. The jacket 8 is realized as an injection/casting jacket and forms the jacket 8 which is in contact with the connection region 22 completely surrounding the first cable 4 a. The sheath 8 thus serves to seal the conductor section 6 in the connection region 22 at the first contact 18 a. In the assembled state, the sheath 8 is thus arranged completely surrounding the conductor section 6 and the first contact 18a in order to seal them from the environment. In addition, the sheath 8 extends as far as, seen along the first cable 4a, so that the sheath completely encloses the sleeve 9 in its longitudinal direction. The sleeve 9 is thus completely embedded in the envelope 8. The jacket 8 thus also encloses the longitudinal section 7 of the first cable 4a from the outside. In addition, it can be seen in fig. 4 that the sheath 8 is also arranged on the mutually opposite axial sides of the flange 11 and is thus firmly supported on the flange 11. Thereby causing the sheath 8 (via the sleeve 9) to be additionally axially fixed to the respective first to third cables 4a,4b,4 c.
The envelope 8 is made of a thermosetting plastic material, but in other embodiments is also made of a thermoplastic plastic material. The envelope 8 is therefore particularly resistant to corrosion-promoting environmental conditions that occur during operation of the vehicle.
As is also apparent from fig. 4, the second cable 4b and the third cable 4c are surrounded by the same sheath 8 at their (second and third) contacts 18b,18c in the same manner as the first cable 4 a. The fourth cable 4d has a sheath, which is separate from the sheath 8 and is not further described.
In other words, according to the invention, the sleeve 9 is applied to the wire housing (insulating housing 5) by means of a tool, for example a crimping tool, said sleeve thereby being connected in a form-fitting manner to the wire housing 5. Compression is created between the outer cover 5 and the sleeve 9, which provides a seal. The plastic (jacket 8) bonds better at the sleeve 9 than on the various wire casing materials and thus provides a higher tightness over a shorter distance, as well as a higher thermal and mechanical stability. Due to the curled profile (see figure), the sealing distance along the sleeve 9 is prolonged (compared to a labyrinth seal) in addition to a better connection. The sleeve 9 additionally increases the mechanical load capacity of the system. The tensile force of the wires (wires 4a,4b,4 c) is significantly greater than without the sleeve 9. During the injection molding process, the cable jacket (insulating housing 5) encounters relatively high temperatures (up to 180 ℃) and thus expands accordingly. After cooling the wires 4a,4b,4c and the injection-molded encapsulation 8 in the subsequent injection-molding process, a gap may occur between the wire jacket 5 and the thermosetting plastic (jacket 8) without the sleeve 9 due to the different expansion coefficients; however, the sleeve 9 prevents gaps from forming during injection molding.
