Definitions
- the invention relates to an actuator for a parking locking system of a vehicle gearbox, in particular a motor vehicle equipped with an automatic gearbox, for example a hybrid vehicle.
- the invention also applies to a parking locking system for a reduction gear associated with an electric vehicle motor. This locking system is better known by its English term “park-lock” or “parking lock”.
- Such an actuator allows the gearbox to be locked in park by means of a lever engaging with teeth on the gearbox.
- the present invention proposes an actuator for a parking locking system of a vehicle gearbox, said actuator comprising a housing having a first volume in which is housed an electric motor having a front face and a rear face and a second volume in which are housed a reduction mechanism in kinematic connection with the electric motor and a torque output element, the first volume is separated from the second volume by a wall in which there is a circular opening allowing an output shaft of the electric motor to pass through, the opening comprises at least one flat disposed at its periphery and the front face of the electric motor comes into contact lodge in the opening in order to be in contact with the at least one flat.
- This arrangement has the advantage of limiting as much as possible the contact(s) of the front face of the electric motor in the housing while ensuring reliable and functional mounting of the electric motor in the housing allowing minimum wear of the wheel gear system and endless screw.
- This arrangement also has the advantage of perfectly immobilizing the front face of the electric motor in the housing without creating play at the level of the bearing or internal bearing of the front face which can lead to defects in the electric motor during vibrations due to a poor immobilization.
- the front face of the engine is cylindrical.
- the front face of the motor is the part of the motor receiving the bearing or the bearing used to guide the rotation of the motor shaft.
- three flats are arranged at the periphery of the circular opening and two of these flats are arranged on a side opposite the reduction mechanism relative to the output shaft of the electric motor. This three-flat arrangement ensures even more reliable and functional mounting of the electric motor in the housing.
- two flats are arranged on a side opposite the reduction mechanism relative to the output shaft of the electric motor. This arrangement makes it possible to be in opposition to the forces generated by the reducing mechanism.
- a recess is located in the wall facing a flat in order to allow bending of the material of the wall between the flat and the recess.
- the material distance between the flat and the wall recess is between 1 and 3mm.
- each flat is angularly spaced by approximately 120°, which allows optimal arrangement on the periphery of the circular opening. A tolerance of plus or minus 10% may be applied.
- the wall comprises at least one passage for at least one power supply spindle of the electric motor.
- the first volume extends partially into the second volume.
- the case is one-piece and made of plastic. These characteristics make it possible to obtain an actuator that is compact, light and simple to produce.
- the first volume is closed by means of a first cover which ensures centering of the rear face of the electric motor and allows the front face of the electric motor to be maintained in position in the circular opening.
- Figure 1 represents an actuator 1 of the parking locking system of a gearbox according to the invention.
- the term gearbox also designates a reduction gear associated with an electric motor in the case of an electric vehicle. More precisely, this actuator 1 comprises a one-piece housing 10 composed of a first volume V1 and a second volume V2.
- the first volume V1 of tubular shape there is an electric motor 20 of the brushless direct current type, this electric motor comprises an output shaft 23. Any other type of electric motor falls within the scope of this invention, such as for example a DC motor with brushes.
- the second volume V2 of parallelepiped shape there are mainly a reduction mechanism 70 in kinematic connection with the electric motor 20 and two electronic cards.
- the first volume V1 is closed by means of a first cover 12 and the second volume V2 is closed by means of a second cover.
- the first cover 12 is fixed to the housing 10 via metal clips 13.
- the second cover is fixed to the housing 10 by any conventional fixing means, for example screws.
- the reduction mechanism 70 comprises a endless screw 22 positioned on the output shaft 23 of the electric motor 20 and meshes with a toothed wheel 30 on which the torque output element 80 is located.
- This output element of couple 80 is produced in the form of a shaft concentric with the toothed wheel 30, the end of which has the shape of a female star socket in which an actuating rod (not shown) of a system is able to come locking so as to lock or unlock a tooth of the gearbox (not shown) via an actuating lever or latch (not shown).
- the torque output element 80 can be made in the form of a male plug.
- This torque output element 80 is guided in rotation by a barrel of the housing 10.
- a sealing means is positioned in this barrel in order to ensure that external pollutants do not enter inside the actuator 1.
- a sealing means is provided between the cover 14 and the housing 10 and between the cover 12 and the housing 10.
- Figure 1 also shows that the first volume V1 is separated from the second volume V2 by a wall 19 in which there is a circular opening 100 allowing the output shaft 23 of the electric motor 20 to pass.
- this opening comprises three flats 100a, 100b, 100c arranged at its periphery and the front face 20a of the electric motor 20 is housed in the opening 100 in order to be in contact with the flats 100a, 100b, 100c.
- This circular opening 100 will be detailed with reference to Figure 3.
- the wall 19 also includes three passages 120, 130, 140 for the three power supply pins of the electric motor 20.
- Housing 10 is in one piece and made of plastic.
- the first volume V1 extends partially into the second volume V2.
- the housing 10 also includes an electrical connector 15 making it possible to electrically connect the internal components to the actuator 1.
- Fixing means 11 in the form of metal inserts are arranged in several locations of the housing 10 in order to be able to fix it to the gearbox of the vehicle. In the present case, three inserts 11 are provided.
- a reference mark X, Y, Z is illustrated.
- the direction or axis X corresponds to a longitudinal direction.
- the transverse Y direction or axis is defined as being perpendicular to the longitudinal direction X.
- the Z direction or axis corresponds to a vertical direction.
- FIG. 2 shows more precisely the integration of the electric motor 20 in the housing 10.
- the electric motor 20 of the brushless direct current type is provided with stator coils, a rotor and an output shaft 23 linked to the rotor and extending along an axis X.
- the stator coils forming the stator of the electric motor are three in number.
- the electric motor has a front face 20a and a rear face 20b, the front face 20a of the electric motor 20 is housed in the opening 100.
- a multi-pole magnet 21 is fixed on the output shaft 23 of the electric motor 20.
- the magnet 21 is annular in shape and is coaxial with the output shaft 23.
- the magnet 21 has four poles. Of course, magnet 21 can have a different number of poles.
- the reduction mechanism 70 comprises a worm screw 22 positioned on the output shaft 23 of the electric motor 20 and meshes with a toothed wheel 30 on which the torque output element 80 is located.
- the output element of torque 80 extends along a Z axis.
- the output shaft 23 of the electric motor 20 is guided in rotation by three bearings and/or bearings.
- a first bearing 18 and a bearing 17 are housed at both ends of the carcass of the electric motor and a bearing 16 is housed in the housing 10 to guide the end of the shaft 23 of outlet opposite the rotor. More precisely, the bearing 17 is housed in the front face 20a and the bearing 18 is housed in the rear face 20b of the electric motor 20.
- the first volume V1 is closed by means of the first cover 12 which ensures centering of the rear face 20b of the electric motor 20 and allows the front face 20a of the electric motor 20 to be maintained in position in the circular opening 100.
- the first cover 12 has an annular shape allowing it to cooperate with the rear face 20b of the electric motor.
