Description

[0001] The invention relates to a parking lock mechanism for parking a vehicle and a vehicle having the parking lock mechanism.

[0002] DE 10 2020 203 033 A1 discloses a conventional electromechanical actuator for a parking lock system having a ratchet (also referred to as a “parking lock wheel”) and a pawl. The parking lock system includes an adjusting mechanism that works in a manner similar to the ballpoint pen mechanism of a push-button ballpoint pen (also referred to as a “ballpoint pen mechanism”). The adjusting mechanism constitutes a bistable locking mechanism that locks or locks a bolt in an extended position of the bolt and a retracted position of the bolt, wherein the adjusting mechanism moves between these positions in a translational and rotational manner as in a ballpoint pen. The bolt that is moved and locked by the adjusting mechanism acts together with a crank lever on a pawl that is movable about a pawl axis, thereby causing the pawl to move and be locked between a position in which it is engaged in the teeth of the ratchet wheel and a position in which it is not engaged in the teeth of the ratchet wheel (see in particular the above-mentioned document). Figure 5 .1 and Figure 5 .2).

[0003] Furthermore, conventional parking lock systems are known in which a bistable locking mechanism is formed by means of permanent magnets, for example by means of a BLDC (brushless direct current motor).

[0004] However, these parking lock systems have the disadvantage that the bolt in its extended position causes the engagement of the pawl by means of a toggle lever. In the aforementioned adjustment mechanism (as also in a ballpoint pen), in the phase between the retracted state and reaching the locked extended state ("actuated position"), an overextension must occur, i.e., an extension beyond the extended state (also referred to as "overcoming the dead center"). This, in conjunction with the toggle lever, causes the pawl to be pressed into the ratchet with increased pressure and increased engagement depth, which can damage the ratchet and / or the pawl and increase their wear.

[0005] The object of the present invention is to overcome the above-mentioned disadvantages of conventional parking lock systems and parking lock mechanisms. In particular, the object of the present invention is to provide a parking lock mechanism which has lower wear and less damage to the parking lock wheel. In addition, the object of the present invention is to provide a vehicle having these advantages.

[0006] This object is achieved by the features of the independent claims. The dependent claims contain advantageous embodiments of the invention.

[0007] This object is achieved in particular by the subject matter of claim 1. Here, a parking lock mechanism for parking lock in a vehicle has an actuator and a pawl. The actuator is operatively connected to a push rod that can be lifted and lowered in a lifting direction. The pawl is rotatably supported about a pawl axis, is coupled to the push rod, and is configured to engage in a parking lock wheel of the vehicle. Here, the pawl extends when the push rod is retracted and retracts when the push rod is extended.

[0008] In other words, the pawl engages in the parking lock wheel in the retracted state of the push rod and is free, i.e. not engaged in the parking lock wheel, in the extended state of the push rod. For example, the retracted state of the push rod corresponds to the basic state and / or the de-energized state of the actuator, while the extended state of the push rod corresponds to the activated state and / or the energized state of the actuator, so that the pawl is engaged in the basic state of the actuator.

[0009] It can be achieved that a possibly damaging engagement of the pawl is prevented. In particular, when a dead point is overcome, the pawl is prevented from being pressed into the parking lock wheel with excessive pressure and / or lifting (distance) by the present invention.

[0010] In an advantageous embodiment, the pawl is retracted in the lifting direction and free when the extension stroke of the push rod is at its maximum. In other words, the pawl is not engaged in the parking lock wheel while the push rod is extended to its maximum extent. Preferably, the pawl is retracted to its maximum extent when the extension stroke of the push rod is at its maximum, i.e., is furthest from the engagement position or is turned furthest away from the parking lock wheel.

[0011] Further advantageously, the pawl has an elongated hole in which a pin connected to the push rod is movably received.

[0012] Advantageously, the pin passes through the elongated hole substantially perpendicularly to the lifting direction, wherein the pin is guided along the longitudinal extension of the elongated hole.

[0013] Advantageously, the longitudinal extension of the long hole has an angle with reference to the lifting direction, which is not equal to 0° and not equal to 90°. Preferably, the above angle is between 20° and 70°, further preferably between 30° and 60°, and further preferably between 40° and 50°. Preferably, the angle is 45°.

[0014] The elongated hole advantageously serves as a guide rail for the pin. The elongated hole and the pin form a simple and low-wear connection between the pawl and the actuator.

[0015] In an advantageous embodiment, the pawl has a pawl head and a pawl body, the pawl head being configured to engage in the parking lock wheel. The pawl body has two legs connected to each other in an L-shaped manner. The pawl head is arranged at the end of the first of the two legs. Advantageously, the distance between the pawl head and the parking lock wheel is greatest during the state in which the pawl is maximally retracted. This shape of the pawl body creates a geometry of the pawl that is easy to manufacture and highly efficient and low-wear.

[0016] Advantageously, the pawl body has exactly two legs as described above.

[0017] It is further advantageous that the angle between the two legs is equal to or greater than 90°. The angle is advantageously defined as the angle between the basic longitudinal axes of the legs, as can be seen from the embodiments below. The angle is advantageously between 90° and 120°, preferably between 110° and 115°. The setting of the angle is advantageously adapted to the parking lock mechanism of the vehicle, more precisely the distance between the pawl and the parking lock wheel. The above-mentioned angle can also be equal to or less than 90° in some embodiments, for example. By the above-mentioned adaptation of the angle, the squeezing force of the pawl on the ratchet wheel is advantageously set. In combination with other features of the present invention, the angle does not need to be adapted to the above-mentioned dead point of attack, because the dead point of attack is carried out when the pawl is retracted.

[0018] Preferably, the pawl axis of the pawl is arranged at the connection region of the two legs. The connection region is advantageously defined as the region of the pawl body at which the projections of the legs coincide along their longitudinal axes.

[0019] In other words, advantageously, a through hole for the pawl shaft is arranged at the connection area. It is thus particularly easy to set the pressing force or the lifting / rotation distance of the pawl, because the angle thus substantially corresponds to the lifting / rotation distance of the pawl.

[0020] In an advantageous embodiment, the first leg has a concave side surface which extends from the pawl shaft to the pawl head. Thus, a particularly compact structure of the pawl and thus the parking lock mechanism is achieved, because the pawl can be arranged closer to the parking lock wheel by means of its concave side surface.

[0021] The parking lock mechanism advantageously has a bistable locking mechanism. In an advantageous embodiment, the locking mechanism has a permanent magnet, such as a BLDC (brushless direct current motor). The permanent magnet advantageously is a component of the actuator or forms the actuator.

[0022] In another advantageous design of a parking lock mechanism with a bistable locking mechanism, the actuator has a pin that can be lifted and lowered, which is connected to the locking mechanism. Here, the locking mechanism has the above-mentioned push rod. Advantageously, the above-mentioned operative connection between the actuator and the push rod is formed by the locking mechanism. The locking mechanism is configured to convert the lifting and lowering movement of the pin into the lifting and lowering movement of the push rod, and lock the push rod in a retracted position and an extended position in the lifting direction. By means of this locking mechanism, it is possible to save expensive permanent magnets, which also require more complex control electronics. Instead, the actuator can have a simple magnet coil and an armature that can be lifted and lowered, which can move back and forth in the lifting direction by means of the magnet coil. It is also advantageous that the actuator is energized for each of the two states (engaged and not engaged) or for the actual state change, without the need for permanent energization. These states are maintained by the bistable locking mechanism here, without the need for continued energization (except for state changes).

[0023] Advantageously, the locking mechanism comprises a pressure element connected to the pin, a propulsion element connected to the push rod, and an inner sleeve. Here, the pressure element and the propulsion element are received in the inner sleeve and can move relative to the inner sleeve. In addition, the propulsion element is preloaded and can be moved between at least two positions in the lifting direction by the preload force, and can be rotated in the circumferential direction of the inner sleeve. The first position of these positions corresponds to a state in which the propulsion element is extended in the lifting direction, and the second position of these positions corresponds to a state in which the propulsion element is retracted in the lifting direction.

[0024] Preferably, the inner sleeve has at least one radial protrusion on its inner circumference. The profile of the pressure element has a first inclined section and at least one groove extending in the lifting direction, wherein the protrusion is arranged in the groove of the pressure element, so that the pressure element is arranged in the inner sleeve in a rotationally fixed and lifting and lowering manner. The profile of the propulsion element has a second inclined section, which constitutes a stop surface in the lifting direction and converts the preload force into a torque of the propulsion element. The above-mentioned propulsion element profile also has a protrusion and a groove extending in the lifting direction. When the propulsion element is extended, the protrusion abuts against the second inclined section in the lifting direction and abuts against the protrusion of the propulsion element profile in the circumferential direction. When the propulsion element is retracted, the protrusion is arranged in the groove of the propulsion element profile.

[0025] In an advantageous embodiment, the locking mechanism has a ball, wherein the ball is arranged between the push rod and the thrust element in the lifting direction and converts the movement of the thrust element into a lifting movement of the push rod without a rotational movement. As a result, the rotational movement of the thrust element (the aforementioned torque) which can lock the mechanism in different positions is converted into a pure lifting movement of the push rod, so that overall the lifting movement of the pin is converted into a lifting movement of the push rod.

[0026] Advantageously, the inner sleeve has an inner circumferential stop surface which forms a lower stop for the pressure element in the lifting direction. Here, the locking mechanism has a first compression spring which is arranged between the flange of the pressure element and the stop surface of the inner sleeve in the lifting direction and preloads the pressure element against the pin. This makes it possible for the pressure element to be preloaded back to a basic state in the lifting direction or to be transferable to this state without requiring a pulling force / pulling of the actuator, thereby further simplifying the control and construction of the actuator.

[0027] In another embodiment, the parking lock mechanism has an outer sleeve and an intermediate sleeve, the outer sleeve jointly receiving the actuator and the locking mechanism, and the intermediate sleeve is arranged between the outer sleeve and the inner sleeve in a radial direction. The intermediate sleeve is fixedly connected to the inner sleeve, wherein the intermediate sleeve and the inner sleeve can move relative to the outer sleeve and inside it in a lifting direction.

[0028] The intermediate sleeve advantageously surrounds the end of the thrust element opposite to the pressure element (in the lifting direction).Preferably, the intermediate sleeve surrounds the flange of the push rod.

[0029] Preferably, the parking lock mechanism has a second compression spring which is arranged radially between the intermediate sleeve and the outer sleeve and which preloads the intermediate sleeve and the inner sleeve (jointly) relative to the outer sleeve.

[0030] In an advantageous embodiment, in which the intermediate sleeve as described above surrounds the flange of the thrust element and / or the push rod and the parking lock mechanism has a second compression spring, the push rod and / or the thrust element, in particular together with the ball, is preloaded against the pressure element in the lifting direction. This enables a particularly simple, low-wear and reliable locking.

[0031] The invention also relates to a vehicle, in particular a motor vehicle, having a parking lock mechanism and a parking lock wheel according to one of the preceding embodiments.

[0032] Further details, advantages and features of the invention will be apparent from the following description of exemplary embodiments with the aid of the accompanying drawings. In the drawings:

[0038] Figure 6 A schematic diagram of a vehicle according to the invention is shown.

[0039] First, with the help of Figure 1 The basic structure of a parking lock mechanism for parking lock in a vehicle according to an embodiment of the present invention is described. Figure 1 A schematic cross-sectional view showing a parking lock mechanism according to an embodiment of the present invention.

[0040] The parking lock mechanism 1 has an actuator 20. The actuator 20 has a yoke 2, a coil frame 5 with a winding 6, an armature 7 and a pole core 8. The armature 7 is received in a manner movable back and forth relative to the pole core 8 along the lifting direction 3 by energizing the winding 6. The actuator 20 also has a housing 4, which receives the yoke 2, the armature 7, the pole core 8 and the coil frame 5.

[0041] The actuator 20 is in operative connection with the push rod 14 which is movable in a lifting direction 3. In other words, the lifting movement of the actuator 20 (more precisely, the armature 7) causes the lifting movement of the push rod 14. Figure 1 and Figure 2 To illustrate this point.

[0042] The parking lock mechanism 1 also has a pawl 19 which is rotatably supported about a pawl shaft 22. The pawl 19 is coupled to the push rod 14 and is configured to engage with the vehicle (see Figure 6 )'s parking lock wheel (not shown).

[0043] Here, with particular reference to Figure 3 and Figure 4 As explained, the pawl 19 extends when the push rod 14 is retracted and retracts when the push rod 14 is extended.

[0044] It can be achieved that the maximum lifting / rotation distance of the pawl 19 is determined by the basic position of the armature 7 ( Figure 1 The highest possible position in the vehicle is limited and defined, thereby preventing the pawl 19 from exerting excessive pressure on the parking lock wheel.

[0045] exist Figure 3 and Figure 4 This is demonstrated in Figure 3 2 is a perspective view of a parking lock mechanism 1 according to an embodiment of the present invention in an unlocked state. Figure 3In particular, the push rod 14 is shown in its most extended state, in which the pawl 19 is free (not engaged in the parking lock wheel).

[0046] Here, in Figure 4 2 is a perspective view of a parking lock mechanism 1 in a locked state according to an embodiment of the present invention. Figure 4 In particular, the push rod 14 is shown in its most retracted state, in which the pawl 19 is locked (engaged in the parking lock wheel).

[0047] The pawl 19 has an elongated hole 23 in which the pin 18 connected to the push rod 14 is movably received. Here, the pin 18 passes through the elongated hole 23 substantially perpendicularly to the lifting direction 3. Figure 1 , Figure 3 and Figure 4 It can be seen that the pin 18 is guided along the longitudinal extension 24 of the elongated hole 23 .

[0048] The lifting / rotating movement of the pawl 19 can be limited by the maximum lifting distance of the actuator 20 , in particular the armature 7 of the actuator 20 , and / or the longitudinal extension 24 of the elongated hole 23 .

[0049] The pawl 19 also has a pawl head 25 which is configured for engagement in a parking lock wheel and a pawl body 26 .

[0050] The pawl body 26 has two legs 27 and 28 (a first leg 27 and a second leg 28 ) connected to each other in an L-shape. The pawl head 25 is arranged at the end of the first leg 27 .

[0051] Here, "L-shaped" does not necessarily mean a 90° connection. The angle 29 between the two legs 27, 28 is advantageously greater than or equal to 90°, preferably approximately 110°. The angle 29 is advantageously defined as the angle between the substantially longitudinal axes 30 of the legs 27, 28, such as Figure 1 shown.

[0052] The pawl shaft 22 is arranged at the connection area 31 of the two legs 27, 28. The connection area 31 is advantageously defined as the area of ​​the pawl body 26 where the projections of the legs 27, 28 (projections of the outer boundaries of these legs) coincide along their longitudinal axis 30. In the present embodiment, the two legs 27, 28 are integrally formed or integrally connected to each other. In particular, the two legs 27, 28 are designed to be integral with each other.

[0053] In addition Figure 1 It can be seen in FIG. 2 that the first leg 27 has a concave side surface 32 which extends from the pawl shaft 22 to the pawl head 25 .

[0054] The pawl 19 is thus mounted rotatably about the pawl shaft 22 , so that a lifting and lowering movement of the push rod 14 causes a rotational / lifting movement of the pawl head 25 to engage it in the parking lock wheel.

[0055] If with the help of Figure 1 , Figure 2 and Figure 5 As can be seen, the parking lock mechanism 1 also has a bistable locking mechanism 21. The locking mechanism 21 allows the push rod 14 or the pawl 19 to be locked in different positions, especially the unlocked position of the pawl 19 (see Figure 3 ) and the locked position of the pawl 19 (see Figure 4 ).

[0056] As described above, the actuator 20 is in operative connection with the push rod 14. In the present embodiment, the actuator 20 has a pin 43 that can be moved up and down, which is connected to the locking mechanism 21. The locking mechanism 21 has the push rod 14 and is configured to convert the lifting movement of the pin 43 by means of the actuator 20 into the lifting movement of the push rod 14 and lock the push rod 14 in a retracted position in the lifting direction 3 ( Figure 4 ) and the extended position ( Figure 3 ).

[0057] The locking mechanism 21 has a pressure element 11 connected to the pin 43, a thrust element 12 connected to the push rod 14, and an inner sleeve 9. Here, the pressure element 11 and the thrust element 12 are received in the inner sleeve 9 and can move relative to the inner sleeve in the lifting direction 3.

[0058] Furthermore, the propulsion element 12 is preloaded here and can be moved between at least two positions in the lifting direction 3 by the preload force and can be rotated in the circumferential direction 33 of the inner sleeve 9. The first of these positions corresponds to a state of the propulsion element 12 extended in the lifting direction 3, and the second of these positions corresponds to a state of the propulsion element retracted in the lifting direction 3.

[0059] The inner sleeve 9 has an inner circumferential stop surface 34 which forms a lower stop for the pressure element 11 in the lifting direction 3 (see Figure 1 ). The locking mechanism 21 has a first compression spring 16 which is arranged in the lifting direction 3 between a collar 35 of the pressure element 11 and a stop surface 34 of the inner sleeve 9 and preloads the pressure element 11 against the pin 43 .

[0060] In this embodiment, if Figure 5 As can be seen in FIG. 1 , the inner sleeve 9 has at least one radial projection 36 on its inner circumference. Figure 5 The inner sleeve 9 is shown in schematic detail and cross-sectional views.

[0061] exist Figure 2 In order to simplify the display and explanation, the inner sleeve 9 is omitted.

[0062] refer to Figure 2 The contour of the pressure element 11 has a first inclined section 37 and a groove 38 extending in the lifting direction 3, wherein the protrusion 36 of the inner sleeve 9 is arranged in the groove 38 of the pressure element 11, so that the pressure element 11 is arranged in the inner sleeve 9 in a rotationally fixed and liftable manner.

[0063] The contour of the propulsion element 12 has second inclined sections 39 which form stop surfaces in the lifting direction 3 and convert the preload force into a torque of the propulsion element 12. The above-mentioned contour of the propulsion element 12 also has a protrusion 40 and a groove 41 extending in the lifting direction 3. In the extended state of the propulsion element 12 (in Figure 2 In the state shown in FIG. 1 , the projection 36 of the inner sleeve 9 abuts against one of the second inclined sections 39 in the lifting direction 3 and against the protrusion 40 of the thrust element profile in the circumferential direction 33. In the state in which the thrust element 12 is retracted, the projection 36 is arranged in the groove 41 of the thrust element 12.

[0064] In order to transfer the propulsion element 12 between the retracted state in which the projection 36 is arranged in the groove 41 of the propulsion element 12 and the extended state in which the projection 36 abuts against the inclined section 39 (whose highest point in the circumferential direction 33 is next to the groove 41 and is farthest from the projection 40), the propulsion element 12 must be pressed in the lifting direction 3 to such an extent that the projection 36 can abut against the inclined section 39. This is also referred to as "overcoming the dead point" or "overextension" because at this stage the propulsion element 12 and the push rod 14 are extended further than in the stable, locked extended state (state in which the pawl 19 is free).

[0065] The parking lock mechanism 1 according to the present embodiment has the advantage that the pawl 19 is in a retracted state under such over-extension. In other words, the pawl 19 is retracted and free in the lifting direction 3 when the extension stroke of the push rod 14 is maximum, thereby avoiding excessive extrusion force on the parking lock wheel.

[0066] The locking mechanism 21 further comprises a ball 13, wherein the ball 13 is arranged between the push rod 14 and the advancing element 12 in the lifting direction 3 and converts the movement of the advancing element 12 into a lifting movement without a rotational movement of the push rod 14. Thus, the rotational movement of the advancing element 12, which can lock the mechanism 21 in different positions, is converted into a pure lifting movement of the push rod 14, so that the lifting movement of the pin 43 is converted into a lifting movement of the push rod 14 as a whole.

[0067] The parking lock mechanism 1 comprises an outer sleeve 10 and an intermediate sleeve 15, which jointly accommodates an actuator 20 and a locking mechanism 21, and is arranged radially between the outer sleeve 10 and the inner sleeve 9. The intermediate sleeve 15 is fixedly connected to the inner sleeve 9, wherein the intermediate sleeve 15 and the inner sleeve 9 can move together in the lifting direction 3 relative to the outer sleeve 10 and in it.

[0068] The intermediate sleeve 15 surrounds the end of the advancing element 12 opposite the pressure element 11 (in the lifting direction 3 ). In this case, the intermediate sleeve 15 surrounds the collar 42 of the push rod 14 .

[0069] Here, the parking lock mechanism 1 has a second compression spring 17, which is arranged radially between the intermediate sleeve 15 and the outer sleeve 10 and preloads the intermediate sleeve 15 and the inner sleeve 9 (jointly) relative to the outer sleeve 10. Here, the push rod 14 and the advancing element 12 are preloaded in particular jointly with the ball 13 in the lifting direction 3 relative to the pressure element 11.

[0070] This design of the parking lock mechanism 1 makes it possible to prevent a potentially damaging engagement of the pawl 19. In particular, when overcoming the dead center / overextension, the invention prevents the pawl 19 from being pressed into the parking lock wheel with excessive pressure and / or lifting (distance). In addition, this design has the advantage that the actuator 20 is energized only for the state change between retracted and extended. Since these states are maintained by the locking mechanism 21, the actuator 20 does not need to be permanently energized.

[0071] Figure 6 A schematic diagram of a vehicle 100 according to the present invention is shown. The vehicle 100 has the parking lock mechanism 1 according to the above-described embodiment and a parking lock wheel (not shown).
