Definitions

  • the invention relates to a pedal force simulation arrangement comprising a cylinder, at least one piston arranged axially displaceably therein, and a force storage arrangement for generating a restoring force on the at least one piston, wherein the energy storage arrangement has at least two force storage units which engage laterally on the piston.
  • a clutch pedal is present in which the pedal is no longer connected to a master cylinder, but the actuation of the clutch takes place by means of an actuator.
  • the clutch pedal is in contrast to a pure automated manual transmission but still available to capture the clutch request of the driver can.
  • the position of the clutch pedal can be detected with a sensor.
  • the pedal must be followed by a pedal force simulation assembly that simulates the force curve that provides the hydraulic link to the pedal.
  • Such a pedal force simulation arrangement is based on the DE 10 2015 202 875 A1 out.
  • This includes a piston-cylinder unit, wherein a complicated spring system engages the piston in order to simulate the desired counterforce on the pedal can.
  • the force accumulation units acting laterally on the piston are arranged asymmetrically.
  • the energy storage of the side attacking springs opposite and symmetrical stored are the energy storage of the side attacking springs opposite and symmetrical stored.
  • the essence of the invention is now to form at least one of the laterally acting springs to the other asymmetric. This makes it possible to produce the same characteristics with fewer energy storage units, as when you can force storage units attack symmetrically.
  • the pedal force simulation arrangement has exactly one piston, which is axially displaceable in the cylinder.
  • the points of attack of the energy storage units on the piston in the axial direction may be at least partially offset from each other. This is a first way to create an asymmetry.
  • the energy storage units may have different lengths. Then the cylinder-side bearing points can be axially at the same height.
  • the cylinder-side bearing points can also be offset axially against one another. Then the energy storage units can be the same length or different.
  • the engagement points can be formed on opposite sides of the piston. In this arrangement, a force acting on the front side spring or acting on the front side of energy storage can be avoided.
  • the force storage unit can be designed as a spring arrangement.
  • Spring assemblies are inexpensive to manufacture and the force characteristics can be safely predict.
  • the force storage arrangement can have exactly two energy storage units, both of which engage laterally on the piston.
  • the side means at the side or the sides and not at the end faces.
  • a can be provided on the front side of the piston attacking spring.
  • the pedal force simulation arrangement preferably only has force storage units which engage laterally on the piston.
  • the energy storage units can each have at least one bearing point or point on the piston, wherein the bearing point is located in a recess of the piston.
  • the bearing point is located in a recess of the piston.
  • the bearing points or points of attack on the piston can be arranged in the axial direction in the central region of the piston.
  • In the middle is basically the whole area of the piston apart from the end areas.
  • the energy storage units attack laterally.
  • two force storage units are provided, which are arranged on opposite sides of the piston or the cylinder. If the first power storage unit in the installed position above, the second is arranged below. As a result, lateral forces can be avoided.
  • exactly one of the laterally acting force storage units can be arranged as an over-center power storage, in particular over-center spring.
  • an energy storage unit is an over dead center power storage depends on the axial point of attack and the piston movement within the cylinder. Accordingly, it can be achieved by the axial offset of the laterally acting energy storage units that only one of the energy storage units acts as Studentstot Vietnamese hearts.
  • the desired characteristic can be achieved with a minimum number of energy storage units.
  • the force storage arrangement can have exactly two energy storage units. These then attack both sides of the piston.
  • the force storage arrangement may comprise at least one force storage unit which is mounted relative to the cylinder at at least one bearing point, wherein the at least one bearing point is arranged on a side surface of the force storage unit.
  • the at least one bearing point may be formed on a housing portion.
  • the pedal force simulation arrangement has further housing sections which are connected to the cylinder. The storage of the energy storage unit accordingly takes place with respect to the cylinder.
  • two bearing points may be formed at opposite locations of the force storage unit.
  • the force storage unit can then be rotatably mounted. Due to the rotatable mounting, it is possible to form the force storage unit as Kochtot Vietnamese Grande Grande maybe. As a result, the characteristics to be generated can be achieved.
  • an energy storage unit can have at least one joint housing and / or one joint shoe and the at least one bearing point can be formed on the joint housing and / or joint shoe.
  • the spring assembly comprises a joint shoe and a joint housing, wherein the joint shoe and the joint housing are arranged at each one end of the spring.
  • the spring arrangement is preferably designed as a helical spring.
  • a joint housing differs from a joint shoe in that the joint housing has a wall on the outside. This surrounds the energy storage assembly on the outside.
  • the wall can embrace the foot of a spring, and thus a wire thickness.
  • the wall can engage around at least one turn of a coil spring.
  • the bearing point is advantageously arranged on a joint housing, since more space is available for the realization.
  • the at least one or the at least two energy storage units at each end of a joint ie a joint shoe or a joint housing
  • the joint housing with which the force storage unit is mounted relative to the cylinder is preferably double-cup shaped.
  • the designed as a spiral spring energy storage is performed particularly well and in addition the joint shoe or a second joint housing can be axially movably connected to the double-headed joint housing.
  • the joint housing or joint housing and joint shoe are axially movably connected to one another.
  • the second joint housing must not be designed as a double pot, however, resulting from the shape as described several advantages.
  • the bearing point may be formed as a bearing pin. This then engages in a recess on a housing portion of the pedal force simulation force assembly.
  • the connecting axis is perpendicular to the longitudinal axis of the cylinder. This allows a stable storage.
  • the storage can be done on the cylinder. This can be done as already described on housing sections which are connected to the housing.
  • the invention relates to a motor vehicle with a pedal force simulation arrangement.
  • the motor vehicle is characterized in that the pedal force simulation arrangement is designed as described.
  • FIG. 1 shows a motor vehicle 1 with a drive unit 2, a clutch 3, a clutch actuator 4 and a transmission 5.
  • the clutch 3 is actuated by means of the clutch actuator 4.
  • the drive unit 2 can be designed as an internal combustion engine and / or electric motor.
  • a pedal 6 in the motor vehicle which is mounted on a pedal block 7 and is connected to a pedal force simulation arrangement 8.
  • the pedal force simulation arrangement 8 simulates the counterforce of a hydraulic path on the pedal 6, as it finds, for example. In motor vehicles with manual transmissions. Since this route is no longer present in a motor vehicle 1 with eclutch it is provided by the pedal force simulation arrangement 8.
  • FIG. 2 shows the pedal force simulation arrangement 8 in a perspective view.
  • the plunger 10 serves to connect to the pedal 6.
  • the plunger 10 is connected to a piston 12 which is arranged axially movable in a cylinder 14.
  • On the piston 12 acts a force storage device 16 comprising two force storage units 18 and 20.
  • the force storage units 18 and 20 are on the cylinder side respectively mounted on housing sections 22 and 24.
  • the housing sections 22 and 24 are firmly connected to the cylinder 14, which is why a bearing on the housing sections 22 and 24 corresponds to a storage relative to the cylinder 14.
  • the construction of the force storage unit 18 essentially corresponds to that of the force storage unit 20; differences are only in the bearing points on the piston 12 or the housing sections.
  • the force storage units 18 and 20 each have a joint shoe 26 for piston-side mounting, which is mounted on the piston 12.
  • the energy storage units 18 and 20 each comprise a coil spring 28 and a joint housing 30.
  • the joint housing 30 are configured double-cup-shaped, d. H. that in a pot with a larger diameter, a pot with smaller diameter is used.
  • a bolt 32 of the joint shoe 26 can engage in the inner pot, so that the joint shoe 26 and the joint housing 30 are guided axially movably against one another.
  • the coil spring 28 engages in the outer pot. Through the two pots, the coil spring 28 is particularly well managed.
  • the bearing points 34 of the joint housing 30 are not on the end face 36, but on the side 38. Since the joint housing 30 has a cylindrical basic shape to the outside, can also be spoken of the lateral surface at which the bearing points 34 are located.
  • the storage of the joint housing 30 on the side allows a reduction of the installation space, since the housing portion 22 no longer has to extend beyond the latter in the axial direction of the force storage unit 18. This means that no housing needs to be present above the end face 36 any more. This also applies to the force storage unit 20. As a result, the space of the pedal force simulation assembly 8 can be at least reduced.
  • a second measure further reduces the installation space. That is, the articulated shoe 26 may be supported inside the piston 12. That is, the bearing point 40 of the Joint housing 26 is disposed in a recess of the piston 12 and thus within the cylindrical piston volume. As a result, space can be saved on both sides of the energy storage units 18 and 20.
  • FIG. 4 shows the pedal force simulation arrangement in a second perspective view.
  • the bearing points 34 as a bearing pin 42, which engage in recesses of the housing portion 22. This also applies to the housing section 24.
