Definitions
- the present invention relates to an electromechanical actuating arrangement for at least one switching element of a vehicle transmission according to the closer defined in the preamble of claim 1.
- Clutch actuator z. B. includes a solenoid valve with which a pressure equalization channel between two piston chambers is closed and opened to control the positioning movements. This results in these arrangements, a complicated structure that requires a considerable amount of space.
- the present invention is based on the object to improve an electromechanical actuator assembly of the type described above such that the most compact design is realized.
- an electromechanical actuating arrangement for at least one switching element, for example for a power shift element of an automatic transmission of a vehicle with at least one drive device, which has a spindle operation of an actuating device for actuating the switching element drives, wherein the adjusting device comprises a lever mechanism operated via the spindle mechanism and wherein the adjusting device is arranged approximately coaxially with a transmission shaft of the vehicle transmission and radially inwardly or radially outwardly provided by the switching element.
- the proposed actuator assembly a high translation is applied by means of the toggle mechanism.
- the electromechanical actuating arrangement can achieve a power saving compared to hydraulic drives by reducing the required hydraulic power.
- expensive channels and hydraulic components that are required for a hydraulic drive can be omitted.
- Another advantage is that with the actuator assembly according to the invention, a start-stop function of an internal combustion engine and a hybrid drive can be realized.
- the toggle mechanism comprises a toggle which is actuated via an axially movable from the spindle drive ramp contour or the like, that the toggle is spread radially, so that coupled to the toggle lever the switching element or can operate the multi-plate clutch.
- a possible embodiment of the invention can provide that the toggle is spread radially outward by means of the ramp contour when the actuator is disposed radially within a disc carrier of the switching element designed as a multi-disc clutch, so that the lever presses the plates of the multi-plate clutch with the applied force to each other or the multi-plate clutch closes. If the adjusting device is arranged radially outside of the disk carrier of the multi-plate clutch, the toggle lever can be spread inwards by means of the ramp contour, so that the lever closes the multi-plate clutch.
- the toggle lever can be spread inwards by means of the ramp contour, so that the lever closes the multi-plate clutch.
- the toggle lever of the toggle mechanism is designed as at least one rotationally symmetrical, bendable sheet metal or the like.
- a multi-part component can be used as a toggle lever, in which then the parts are connected to each other, for example via joints.
- the knee lever is designed so that it has an infinitely large holding function in its dead center.
- the lever of the lever mechanism for actuating the disk set of the multi-plate clutch is arranged coaxially to this and preferably designed as an annular, bendable sheet metal.
- the lever can be operated in the simplest manner on the likewise coaxially arranged toggle.
- a first end of the lever may be coupled to the toggle lever and a second end of the lever may be associated with the multi-plate clutch, the lever being supported fixedly between its ends in order to enable the lever function.
- the toggle mechanism is coupled via the ramp contour with the spindle drive.
- the ramp contour can be formed by a ball ramp or the like
- the first ring half are coupled with the spindle drive and the second ring half via a wedge-shaped element or the like with the toggle lever.
- the two ring halves can, for example, be rotatably supported on one another via at least one rolling element, so that the wedge-shaped element is moved accordingly by an axial adjustment of the spindle drive, so that a radially directed force can be transmitted to the knee lever for spreading.
- the proposed electromechanical actuator assembly may be used to actuate power shift elements in automatic transmissions.
- the proposed electromechanical actuator assembly may be used to actuate power shift elements in automatic transmissions.
- Figure 1 is a schematic representation of the general principle of action of an actuating arrangement according to the invention.
- Figure 2 is a partial sectional view of a first possible embodiment of the actuator assembly according to the invention in a transmission housing of a vehicle;
- Figure 3 is a sectional partial view of a second possible embodiment of the actuator assembly according to the invention in the transmission housing of a vehicle.
- FIG. 1 the general operating principle of the proposed electromechanical actuator assembly is outlined. From this illustration it follows that the actuating arrangement with a drive device designed as an electric motor 1 drives a spindle drive 2 of an actuating device for actuating a switching element, which is exemplified in the drawings as a multi-disc clutch 3.
- the adjusting device further comprises an actuated via the spindle drive 2 toggle mechanism 4.
- the toggle mechanism 4 is a ramp contour of the Spindle drive 2 radially spread to act on the multi-plate clutch 3 with a predetermined force (F La m e ii e ).
- the adjusting device in the actuator assembly according to the invention, can be arranged approximately coaxially with a transmission shaft 5 of the vehicle transmission, wherein the adjusting device is provided radially inside or radially outside relative to the multi-plate clutch 3. In this way, a space-reduced arrangement and at the same time results due to the toggle mechanism used a large translation for actuating the multi-plate clutch. 3
- FIG. 2 shows a first possible embodiment of the proposed actuating arrangement is shown, in which the adjusting device is arranged radially within the disk carrier 5 of the multi-plate clutch 3.
- a second embodiment variant is shown in Figure 3, in which the entire actuator assembly is disposed radially outside of the disk carrier 5 of the multi-plate clutch 3.
- the toggle mechanism 4 includes a toggle lever 6 which is actuated by a spindle drive 2 axially movable ramp contour such that the toggle lever 6 is spread radially, so that coupled to the toggle lever 6 lever 7, the multi-plate clutch 3 is actuated.
- the toggle 6 is designed as a rotationally symmetrical, bendable sheet metal.
- the lever 7 is provided as an annular bendable sheet. Both the lever 7 and the knee lever 6 are each arranged coaxially with the multi-plate clutch 3.
- the ramp contour is formed by a ball lamp 8, the first ring half 9 is coupled to the spindle drive 2 and the second ring half 10 via a wedge-shaped element 1 1 with the toggle lever 6.
- the two ring halves 9,10 are rotatably mounted on each other via rolling elements 12.
- the toggle mechanism 4 is integrated into the space between the plate carrier 13 and the transmission shaft 5, there is a small required space.
- the entire actuator assembly can be arranged radially outside, so as to save space in the interior of the transmission.
