- Shift support device for a manually switchable manual shift transmission
- the present invention relates to a shift assistance device for a manually shiftable manual transmission according to the preamble of patent claim 1.
- Automated manual transmissions are known from the state of the art, which correspond to manually operated manual transmissions with regard to their main components, in which the shifting clutch and the selection and shifting process for the individual gears are effected by means of pneumatically or hydraulically actuatable actuators.
- the shift shaft is rotated by means of a Wählaktuators to Gassen inches and moved axially via a shift actuator for switching.
- the pneumatic piston is mounted on the shift arm and arranged in parallel in the power flow of the shift force, wherein the operation is performed by a dragged valve in the piston in response to the shift force.
- a pressure-regulating device for an actuating means preferably embodied as a piston-and-cylinder arrangement in such a transmission is described, for example, in the context of DE 102 49 341 of the Applicant. It comprises a pressure generating device, a Hauptdruckre ⁇ gelung with appropriate control pressure lines, a sensor for detecting the pressure in a control pressure line, at least one pressure-controlled actuator, switching valves for connecting the control pressure lines with Zuleitun ⁇ gene to pressure chambers of the actuating means and a pressure regulating means for adjusting the pressure level of the main pressure line to the control pressure veau for the actuating means.
- the pressure regulating means is designed as a clocked electromagnetic switching valve.
- the piston-cylinder assembly communicates with the shift shaft of the transmission, so that it is axially displaceable to make a gear selection.
- the circuits are pneumatically supported by a device, wherein the force exerted by a piston-cylinder arrangement for carrying out a shift or for axially displacing the shift shaft is constant; the support means is activated when the shift linkage travels a predetermined distance against the force of a spring.
- the object of the present invention is to provide a shift assistance device for a manually shiftable manual transmission, in which the shift operation on the part of the driver is assisted by a suitable device as a function of the driver's request.
- a suitable device as a function of the driver's request.

- a force sensor is provided in the power flow of the manual shift parts, beispielswei ⁇ se on the shift lever, the signals of which are evaluated by an electronic control, then an operable via valves cylinder-piston assembly which with the shift shaft or a shift fork to the axial movement is in operative connection to control.
- the actuation pressure of the cylinder-piston arrangement depends on the force exerted by the driver on the shift lever.
- At least one pressure regulating valve is actuated by the electronic control, which preferably controls switching valves designed as solenoid valves for the actuation of the cylinder-piston arrangement.
- the cylinder-piston arrangement can be designed to be pneumatically or hydraulically operable.
- Another embodiment of the invention provides that the func tionality of the switching valves in at least one pressure control venti I is integrated so that preferably two with the cylinder-piston assembly directly connected pressure control valves are provided for switching support, each with one side of the cylinder Piston arrangement are connected, wherein the separa ⁇ th switching valves omitted.
- the pressure to be set in the servo cylinder or in the cylinder-piston arrangement is adapted to the driver's request.
- each desired level of force can be adjusted, with harmful increases in force being prevented.
- components already present in automated manual transmissions such as, for example, the cylinders, can advantageously be provided.
- the piston arrangement, the pressure sensors and the pressure regulating and Druckven ⁇ be used.
- Fig. 1 is a schematic representation of the components of a first preferred embodiment of the erfindungsgemä ⁇ Shen switching support device for a manually switchable manual transmission and
- Fig. 2 is a schematic representation of the components of a second preferred embodiment of erfindungsge ⁇ MAESSEN switching support device.
- the inventive Heidelbergunterstweilungsein- device comprises a pressure control venti 1 1, which is preferably designed as a pulsed elektro ⁇ magnetic valve, which is connected via a control line 2 with an electronic control 3.
- the pressure control venti 1 1 is connected via a control pressure line 4 with two preferably designed as solenoid valves switching valves 5 and 6 respectively.
- the electronic control can be designed as a separate component; It is also possible that the shift assistance device is controlled by the transmission control or a higher-level control.
- Fig. 1 is behind the pressure control valve 1 in the control pressure line 4, a pressure sensor 8 arranged to detect the pressure prevailing in the control pressure line 4 pressure.
- the signals of the pressure sensor 8 are passed via a control line 11 to the electronic control 3 and evaluated there, such that in the control pressure line 4 via the operation of the pressure control valve 1, the desired pressure ge is adjustable.
