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.
- US 2006/0 278 489 A1 and DE 102 58 836 A1 disclose electromechanical clutch actuators for a vehicle clutch whose adjustments are controlled via an additional pneumatic or hydraulic system.
- the known from DE 102 58 836 A1 disclose electromechanical clutch actuators for a vehicle clutch whose adjustments are controlled via an additional pneumatic or hydraulic system. The known from DE 102 58 836 A1
- 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 and the lowest possible actuating forces are required.
- an electromechanical actuating arrangement for at least one shifting element or the like of a vehicle transmission is provided with proposed at least one drive device which is coupled to an actuating device for actuating the switching element, wherein the actuating device comprises a operated from a ramp contour or the like toggle mechanism.
- an actuator assembly with a small space requirement can be proposed because the adjusting device is realized by a few components.
- a high translation is applied even at low actuating forces using the actuated by the ramp contour knee lever mechanism.
- the electromechanical actuator assembly By the electromechanical actuator assembly, a power saving compared to hydraulic drives can be achieved 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 actuating arrangement for actuating a multi-plate clutch of a transmission is used, wherein the toggle mechanism is preferably arranged substantially coaxially with the transmission shaft.
- the adjusting device may comprise a spindle drive or the like driven by the drive device, which moves the ramp contour for actuating the toggle mechanism essentially axially.
- the required force can be transmitted to the toggle lever mechanism in the simplest way.
- the toggle mechanism comprises, for example, a toggle element operatively connected to the ramp contour or the like, and an actuating lever or the like operatively connected to the switching element to be actuated. With this operating lever toggle element combination only small actuating forces for actuating the switching element are required. In addition, this results in an advantageous manner, a zero-force holding area or dead center in the actuator assembly.
- an axial force can be applied to the toggle lever element by the ramp contour, so that the toggle lever element is moved radially outward, whereby the actuating lever against the switching element for actuating the same is pressed.
- a toggle element a rotationally symmetrical, bendable sheet metal or the like and the ramp contour can be formed by a ball ramp.
- the ramp contour can be formed by a ball ramp.
- one end of the actuating lever is mounted fixed to the housing via a joint with the toggle lever element and the other end of the actuating lever.
- other structural designs can be used to achieve the above-described operation.
- a preferred application of the actuator assembly according to the invention is the use in a transmission for actuating a multi-disc clutch designed as a switching element, wherein the drive means comprises an electric motor which drives a spindle drive for axially moving the ramp contour or the ball ramp.
- Figure 1 is a schematic representation of the general principle of action of an actuating arrangement according to the invention.
- Figure 2 is a sectional partial view of the actuator assembly according to the invention in a transmission housing of a vehicle.
- 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 actuates a spindle drive 9, a ramp contour and a toggle mechanism 3 comprehensive adjusting device, so that the toggle mechanism 3 is moved accordingly to act on a switching element to be actuated with a predetermined force.
- the adjusting device is formed only by a few components, so that the number of required components is considerably reduced compared to known actuating arrangements.
- FIG. 2 shows a possible variant of the proposed actuating arrangement in a transmission housing 1 of a motor vehicle.
- the electromechanical actuating arrangement comprises a drive device, which is coupled to an actuating device for actuating a switching element designed as a multi-disc clutch 2, wherein the actuating device comprises the toggle mechanism actuated by a ramp contour 3 to transmit a desired actuating force to the multi-plate clutch 2.
- the toggle mechanism 3 is arranged in the transmission housing 1 coaxial with a merely indicated transmission shaft 4. This results in a particularly space-saving arrangement.
- the toggle mechanism 3 comprises a toggle lever element 5 and an actuating lever 6, which are coupled together via a hinge 7.
- the toggle element 5 is z. B. designed as a rotationally symmetric and bendable sheet.
- a ball ramp 8 is provided, which is coupled on the one hand with a spindle drive 9, which is driven by an electric motor 10 of the drive means, and on the other hand with the toggle lever element 5.
- the ball ramp 8 can z. B. be formed as a split ring element or the like, wherein a first half 1 1 the Spi ⁇ deltrieb 9 and a second half 12 associated with the ramp contour of the toggle lever element 5.
- the two halves 1 1, 12 are for example mounted on a plurality of rolling elements 13 to each other. There are also other constructive designs for realizing the ramp or slope contour possible.
- the actuating lever 6 is a rotary member that is supported at the end facing away from the toggle lever element 5 on the transmission housing 1 or mounted in a housing-fixed lever bearing, so that by a spread of the toggle lever element 5, a displacement of the actuating lever 6 is made possible so that this on the slats the multi-plate clutch 2 is pressed.
- the displacement or rotation of the actuating lever 6 is indicated by an arrow in Figure 1.
- the spread of the toggle lever element 5 and also the axial movement of the ball ramp 8 and the spindle nut of the spindle drive 9 are indicated in Figure 1 by corresponding arrows.
- the toggle element 5 is moved by the actuated by the spindle drive 9 second half 12 of the ball ramp 8 in the axial direction, so that the toggle element 5 spreads radially outward.
- the arrangement of the two levers, that is, the actuating lever 6 and the toggle lever element 5, allows a high translation with low actuating force on the ball ramp 8.
- the actuator assembly at dead center of the toggle lever element 5 can remain without restoring force.
