Definitions
- the invention relates to an actuating device for a motor vehicle clutch according to the preamble of claim 1.
- the object of the invention is to provide a fastening device of the type characterized in the preamble of claim 1, which causes a steep increase in power assistance after the dead center position has been exceeded.
- the stored spring force from the tension spring acts as a support torque on the pedal, in particular when it is actuated.
- This support causes a steep response after passing through the dead center position, which is essentially achieved by the arrangement and mounting of the push rod and the tension spring. So the push rod can pivot around the bearing point on the lever arm of the pedal and the spring around its fixed point on the body with the push rod. Even with a small pivoting angle of the pedal, this advantageously has a leaping effect magnifying support moment.
- the actuating device achieves a quick response behavior with a steeply increasing support torque and good tunability when using a few simple components.
- the actuating device for a clutch consists essentially of a clutch pedal 1 with pedal plate 2, which is articulated about a pivot axis 3 on the vehicle body 4.
- the pedal 1 has a protruding lever arm 5 which is connected via a bearing point 6 formed by a pivot bearing to a push rod 7, on which a tension spring 10 articulated on the vehicle body 4 in a fixed point 9 is held in an opposite bearing 8.
- the push rod 7 consists of a U-shaped bracket, the legs 13, 14 of which each have the bearings 6 and 8.
- the spring 10 is arranged embedded between these legs 13, 14.
- the bearing 6 of the push rod 7 on the lever arm 5 is arranged with the smallest possible distance a from the fixed point 9 of the tension spring 10. As can be seen in more detail in FIG. 1, the distance a corresponds approximately to half the width b of the lever arm 5.
- the push rod 7 pivots with the pedal 1 in the direction of the arrow 15 around the bearing 6 and the tension spring 10 around the fixed point 9, which contracts during this process.
- position B of the push rod 7 the end position of the pedal 1 is reached, the support lever arm having reached its maximum value and an action line 16 extending at an acute angle ⁇ to the action line 11.
- FIG. 3 shows the course of the line of action between the pedal position when the clutch is engaged and the clutch is disengaged.
- the line of action 11 with the clutch disengaged causes a lever arm 17, by means of which a restoring moment of the pedal 1 for holding in the rest position is generated.
- the pedal 1 is actuated in the direction of the arrow 15, the line of action 11 passes through the bearing 3 of the pedal 1 and establishes a dead center position with a line of action 11a.
- an action line 16a After passing through this position, for example, an action line 16a generates a support moment for the pedal 1 via the lever arm 18, which increases depending on the pivoting angle of the pedal 1 in the direction of the arrow 15 and can reach its maximum value with the action line 16 and the lever arm 19.
- the course of the support torque over the pedal travel results from the coordination of the kinematics and the spring characteristics, so that, as described above, the maximum value can also be reached before the line of action and with the line of action 16 there is even a lower support torque.
