Definitions

  • the invention concerns a device for actuating a gearwheel designed as a loose wheel of a transmission device.
  • shift elements such as synchronizers, claw or frictional elements are actuated by means of shift forks or shift rockers which, in relation to the shaft carrying the loose wheel or a plurality of loose wheels, act upon the shift elements from the outside.
  • shift forks or shift rockers which, in relation to the shaft carrying the loose wheel or a plurality of loose wheels, act upon the shift elements from the outside.
  • a minimum distance between two loose wheels arranged next to one another, which can be actuated by a common shift element is determined among other things by the width of a shift sleeve and in addition by the shift path that the shift sleeve has to cover in order to engage the two loose wheels.
  • step-down transmissions in which shift elements are actuated from outside take up a lot of space in the radial direction, such space being of only limited availability especially in automobiles.
  • the purpose of the present invention is to provide a device for actuating a component mounted to rotate on a shaft, preferably a gearwheel designed to be a loose wheel of a transmission device, which can be produced simply and inexpensively, takes up little structural space and has low component weight, and whose use enables a transmission to be operated with good efficiency.
  • the at least one electric actuator is arranged at least partially inside the first shaft.
  • the use of the electric actuator and the arrangement of the actuator on the inside of the shaft carrying the loose wheel to be actuated makes it possible in a simple manner to do without any external shifting means known from the prior art, and thus to save structural space in the circumferential area of the shaft. Furthermore, thanks to the structurally more simple design of the engaging device compared with conventional transmission devices, the overall weight of the transmission device is also reduced. In addition, compared with shift systems known from the prior art frictional losses during the actuation of a loose wheel are reduced, due to the smaller diameter range within which an actuation or a transmission of the loose wheel actuating force required for engagement or disengagement of the wheel takes place.
  • the electric actuator is connected in a rotationally fixed manner to a housing of the transmission device, whereby energy exchange and data transfer between the electric actuator and components of a transmission device or of another system comprising the device according to the invention, which are fixed on the housing and which co-operate with the actuator, such as a wedge brake system, can be effected in a simple manner.
  • the electric actuator is connected in a rotationally fixed manner to the shaft carrying the rotating component, and therefore rotates at the speed of the shaft during operation.
  • the electric actuator can be inserted into the shaft before the shaft is fitted into a housing, forming a pre-assembled module with the shaft which, during final assembly of a transmission device or other system, can be fitted into a housing in a single assembly step.
  • the correct operation of the device can be tested using appropriate testing means outside the housing of the transmission device or other system.
  • Another advantageous embodiment of the device for actuating a component mounted to rotate on a shaft is characterized by a drive converter device of the engagement device arranged between the actuator and the component, by means of which a rotary drive of the actuator can be converted into a translational drive movement inside the shaft in a manner advantageous in terms of structural space.
  • the drive converter device is made as a spindle-nut arrangement with or without self-locking, by which the rotary drive of the actuator can be converted by simply designed means and in an inexpensive manner into a translational drive movement for producing the actuation force needed to engage or disengage the component.
  • an advantageous embodiment of the device according to the invention is made with a transmission, preferably a planetary transmission 22 ( FIG. 1 ), between the actuator and the drive converter device, by means of which the drive power of the electric actuator can be transformed to a value necessary for actuating the component.
  • the electric actuator is made as an electric motor by means of which, preferably, an existing shift status of the component can be maintained, so that there is no need for additional structural elements to maintain the shift status of the component.
  • an electrically controlled brake is associated with the actuator to maintain the shift status of the component, this brake preventing any change of the component's shift status when it is not energized.
  • the actuator can be controlled and/or regulated as a function of an existing shift status of the component and/or of a currently necessary drive power. For example, if driving the actuator actuates a shift claw that engages a loose wheel of a transmission device, then the actuator's operation is controlled and/or regulated depending on the current position of the shift claw. If a frictional disk-type shift element of a transmission is controlled by the actuator, then the drive power of the actuator is adjusted under control and/or regulation since the torque that can be transmitted by a disk-type shift element depends on the actuating force applied to its frictional elements.
  • FIG. 1 A schematic partial longitudinal section view of a first example embodiment of a device according to the invention, arranged in a step-down transmission;
  • FIG. 2 Representation corresponding to that of FIG. 1 , of a second example embodiment of the device according to the invention, used for engaging and disengaging loose wheels of a step-down transmission.
  • FIG. 1 shows part of a transmission device 1 made as a step-down transmission, seen in a longitudinal section view, which comprises a main transmission shaft 2 and arranged parallel to it, a countershaft 3 .
  • a transmission shaft 2 On the main transmission shaft 2 are arranged a plurality of gearwheels 2 A to 2 D made as fixed wheels, which mesh with a plurality of gearwheels 3 A to 3 D mounted to rotate on the countershaft and made as loose wheels.
  • the loose wheels 3 A and 3 B can be engaged by means of a first engaging device 4 A of a device 4 for actuating the gearwheels 3 A to 3 D, whereas the loose wheels 3 C and 3 D can be engaged and thus connected in a rotationally fixed manner to the countershaft 3 by means of a second engaging device 4 B of the device 4 .
  • the engaging devices 4 A and 4 B of the device 4 have basically the same structure, so in the description of FIG. 1 below, essentially only the engaging device 4 A will be described.
  • the engaging device 4 A is made with an electric actuator 5 in this case consisting of an electric motor and, associated with the electric actuator 5 , a control and power electronic unit 6 , both of which are connected in a rotationally fixed manner to a housing component 7 of the housing of the transmission device 1 .
  • a motor output shaft (not shown) of the electric actuator 5 is connected in a rotationally fixed manner to a spindle 8 A of a spindle-nut arrangement 8 , so that when the actuator drives the spindle 8 A it rotates and a nut 8 B engaged with the spindle, which is prevented from rotating by anti-rotation means (also not shown), is moved in the axial direction of the countershaft 3 away from the electric actuator 5 or toward it.
  • the nut 8 B is actively connected to two pins 9 A and 9 B that pass through the countershaft 3 in such manner that the pins 9 A and 9 B are pushed by the nut 8 B in the axial direction of the countershaft 3 along slots 10 A, 10 B of the countershaft 3 .
  • the pins 9 A and 9 B rotate at the speed of the countershaft 3 about the rotation axis of the countershaft 3 , whereas the nut 8 B cannot rotate. This means that in the area between the pins 9 A and 9 B and the nut 8 B for actuating the loose wheels 3 A and 3 B, speed decoupling means are provided.
  • the pins 9 A and 9 B are connected at their end remote from the nut 8 B to a sleeve element 11 that surrounds the countershaft 3 and which is connected in a rotationally fixed manner to the countershaft 3 by a form-locking connection but which can move along the countershaft 3 in the axial direction of the countershaft 3 .
  • the sleeve element 11 is has a toothed profile 11 A which, depending on its axial position, engages with a toothed profile 12 connected fixed to the loose wheel 3 A, or with a toothed profile 13 connected fixed to the loose wheel 3 B, or is in a neutral, intermediate position between the two toothed profiles 12 and 13 and engages with neither of them, so that neither the loose wheel 3 A nor the loose wheel 3 B is connected in a rotationally fixed manner to the countershaft 3 .
  • the spindle-nut arrangement 8 and the spindle-nut arrangement 14 in each case constitute a drive conversion device by means of which rotary drive of an electric actuator can be converted to translational drive movement for engaging or disengaging the loose wheels 3 A to 3 D.
  • the spindle-nut arrangements 8 and 14 are of self-locking design so that without being driven by the actuator the nut 8 B of the spindle-nut arrangement 8 or the nut 14 B of the spindle-nut arrangement 14 will hold their position.
  • the device for actuating a component mounted to rotate on a shaft or a gearwheel of a transmission device made as a loose wheel
  • a shift status of the component can be maintained by appropriate control of the electric actuator of the engaging device by means of a retaining torque produced by the actuator.
  • an electrically controlled brake is associated with the actuator, which prevents a change of the component's shift status when it is not energized.
  • the electric actuator is made as an electric motor the brake 24 is connected to the motor output shaft, so that rotary movement of a spindle of a spindle-nut arrangement is prevented when the electric motor is not energized.
  • an energy accumulator 7 7A for the storage of electrical energy is also provided, which in the present case is in the form of a capacitor by means of which a voltage supplied to the electric actuator is smoothed.
  • the energy accumulator 7 7A preferably in the form of a capacitor can also be used for the interim storage of electrical energy needed for operating the electric actuator 5 .
  • the structural unit constituting a module and containing the energy accumulator 7 7A, the control and power electronic unit 6 and the electric actuator 5 is also provided with oil ducts 20 through which, inside the countershaft 3 , hydraulic fluid for lubrication, cooling or actuating various components of the transmission device 1 is passed to the components concerned.
  • the device 4 for actuating the loose wheels 3 A to 3 D which comprises the engaging devices 4 A and 4 B, is formed in the area between the electric actuator 5 and the spindle-nut arrangement 8 and an electric actuator 17 and the spindle-nut arrangement 14 , in a manner not illustrated, in each case with a transmission device in order to be able to transform the drive power of the electric actuator 5 by the necessary amount and to be able to drive the spindle 8 A and a spindle 14 A, respectively, with the torque required for the axial displacement of the spindle nuts 8 B and 14 B.
  • FIG. 2 shows a second example embodiment of a transmission device 1 , which is different essentially only in the design of the device 4 for actuating the gearwheels 3 A to 3 D, so that in the description below essentially only the differences will be described.
  • the electric actuators 5 of the device 4 for actuating the loose wheels 3 A to 3 D are connected in a fixed manner to the countershaft 3 and therefore, during the operation of the transmission device 1 , they rotate at the speed of the countershaft 3 . Accordingly, no longer is any mechanical speed decoupling needed in the area between the spindle nuts 8 B and 14 B and the bolts 9 A, 9 B and 16 A, 16 B.
  • Energy and/or control signal transmission between components 26 provided outside the countershaft 3 and fixed on the housing and the actuators 5 and 17 connected in a rotationally fixed manner to the countershaft 3 is in this case carried out by a rotary transmitter 15 that works on the induction principle.
  • a rotary transmitter 15 that works on the induction principle.
  • the inductive rotary transmitter 15 both the drive energy needed for driving the electric actuators 5 and 17 , and also the necessary two-directional control signals 28 , i.e. nominal and actual values, are exchanged with no contact.
  • these can also be transferred by an appropriate sliding contact system 30.
  • Both of the engaging devices 4 A and 4 B are parts of a module which can be inserted in its entirety into the inside of the countershaft 3 during assembly.
  • a rotation of the module preferably by 900 90 degrees to its axial end position is provided for, in order to form a connection between the spindle nuts 8 B and 14 B and the pins 9 A, 9 B and 16 A, 16 B respectively.
  • the module is connected in a rotationally fixed manner to the countershaft 3 by suitable means such as a clip connection, a screw connection, a pin connection, a bonding connection or by wedging.
  • the device is made with only one electric actuator for applying the actuation force for the engagement or disengagement of a component or gearwheel, this being a so-termed dedicated selection actuator.
  • the selection actuator By means of the selection actuator a choice can be made between the various components or gearwheels to be actuated, so that by means of the selection actuator a selected gearwheel or component, or the shift element associated with it, is acted upon by the actuation energy produced by the electric actuator.
  • the selection actuator is in this case preferably made as a shift magnet, which produces the connection between the electric actuator of the device and the component or gearwheel to be actuated by the device that is necessary for the component or gearwheel, or the shift element associated with it, to be actuated.
  • the device described above is also suitable for other self-reinforcing systems such as wedge brakes or wedge clutches, so that the system provided for actuating the elements can simply be made as a module and fitted in an appropriate position.
