Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 7, the phaser actuator 100 includes a housing 101, a main shaft 103, a shift structure 105, a first power mechanism (i.e., an auxiliary power mechanism) 107, a second power mechanism (i.e., a main power mechanism) 109, helical gears 1130a to 1130j, gears 113a to 113j, and output units 111a, 111b, 111c, 111d, 111e, 111f, 111g, 111h, 111i, and 111j, wherein the gears 113a to 113j are respectively connected to the helical gears 1130a to 1130j through transmission shafts (not shown), and each output unit is provided with a rack engaged with a corresponding worm of the gears 113a to 113j, such that the gears 113a to 113j can drive the corresponding output unit to move when rotating, thereby driving the corresponding phaser to generate motion. Wherein the housing 101 includes a sub-housing 101a and a sub-housing 101b adapted to the sub-housing 101a, the main shaft 103 is disposed in the sub-housing 101b (it should be understood that the main shaft 103 may also be disposed on the sub-housing 101 a).
As shown in fig. 2, 3a and 7, the main shaft 103 is provided with worms 104a and 104b movable in the axial direction of the main shaft 103. Here, the provision of the two worms 104a and 104b is merely exemplary and not restrictive, and one or more worms may be provided as necessary. The main shaft 103 is further provided with a worm gear 103g, and it should be understood by those skilled in the art that the main shaft 103 and the worm gear 103g are generally fixedly connected, i.e., do not rotate relatively. The shift structure 105 is movably (e.g., in a direction perpendicular to an axial direction of the main shaft 103) disposed within the housing 101. It should be understood that although two worms are provided on the main shaft 103 in the embodiment shown in the figures, in other embodiments only one worm or more than three worms are provided on the main shaft 103.
As further shown in fig. 3a and 7, the gear shift structure 105 is provided with a rack 105a arranged in a direction parallel to the axial direction of the main shaft 103. When the gear shift structure 105 is in the first position, the worm 104a and the worm 104b are engaged with the rack 105a, and at this time, the driving by the second power mechanism 109 will cause the worm 104a to change the positions of the worms 104a and 104b on the main shaft 103 by means of the rack 105a, thereby enabling the selection of different output units 111a, 111b, 111c, 111d, 111e, 111f, 111g, 111h, 111i, 111j, and thus the selection of different phase shifters. At this time, the worm wheel 104a and the worm wheel 104b do not mesh with the helical gears 1130a to 1130j above them. Accordingly, when the shift structure 105 is in a second position different from the first position, the worm 104a and the worm 104b are not meshed with the rack 105a but are meshed with the bevel gears 1130a to 1130j above the worm, and the worm 104a is meshed with the corresponding output units 111a, 111b, 111c, 111d, 111e, 111f, 111g, 111h, 111i, 111j by the bevel gears 1130a to 1130j above the worm through the driving of the second power mechanism 109, so that the corresponding phasers are driven.
In addition, the shifting structure 105 is further provided with a shifting rack 105B arranged along the direction perpendicular to the axis of the main shaft 103, and the shifting rack 105B on the shifting structure 105 has a limit a and a limit B (as shown in fig. 7). In this way, the shifting arrangement 105 can be shifted between the first and second positions described above by means of the shifting rack 105B with limit a and limit B.
Furthermore, as shown in fig. 3a to 7, the first power mechanism 107 is disposed on the sub-housing 101b, the first power mechanism 107 includes a motor 107a, a transmission shaft 107b and a worm 107c connected to the motor 107a through the transmission shaft 107b, the worm 107c is engaged with the switching rack 105b, the second power mechanism 109 is also disposed on the sub-housing 101b and coupled to the main shaft 103, and specifically, the second power mechanism 109 includes a motor 109a, a transmission shaft 109b, a driving gear 109c, a driven gear 109d, a transmission shaft 109e and a worm 109 f.
When the phase shifter transmission 100 is operated, the motor 107a drives the worm 107c to rotate through the transmission shaft 107B so that the worm 107c moves between the limit a and the limit B of the switching rack 105B. When the worm 107c is located at the limit B, the gear shifting structure 105 enables the worms 104a and 104B to be in the operating state of the gear shifting and position selecting mode, at this time, the worms 104a and 104B are meshed with the rack 105a, the motor 109a drives the driving gear 109c to rotate through the transmission shaft 109B, and the driven gear 109d follows the driving gear 109c to rotate. Further, the driven gear 109d drives the worm 109f to rotate through the transmission shaft 109e, so as to drive the worm wheel 103g to rotate, and further drive the main shaft 103 to rotate, and the worms 104a and 104b can move to a target gear (i.e. a gear where the target output unit is located) along with the rotation of the main shaft 103.
When the worm 107c is located at the limit a, the gear shifting structure 105 enables the worms 104a and 104b to be in the driving mode, at this time, the worms 104a and 104b are respectively separated from the rack 105a and respectively meshed with, for example, the bevel gears 1130a and 1130f, and the worms 104a and 104b move along with the rotation of the main shaft 103 (it is understood that the moving direction depends on the main shaft rotation direction and the worm rotation direction), so as to drive the bevel gears 1130a and 1130f to rotate. Accordingly, the gears 113a and 113f are driven to rotate, and further, the gears 113a and 113f drive the corresponding output units 111a and 111f to move through the racks engaged with the gears, so as to drive the phase shifters connected with the output units 111a and 111f to move. Further, the shift structure 105 is provided with a number of stopper portions (e.g., stopper grooves 105c) corresponding to the number of gear positions, and restricts the degrees of freedom of the worms 104a and 104b in the axial direction, that is, prevents the worms 104a and 104b from moving in the axial direction of the main shaft 103 while rotating with the rotation of the main shaft 103.
In another embodiment, the first power mechanism 107 and the shift structure 105 are provided with an electromagnetic relay, wherein an electromagnet of the electromagnetic relay is arranged on the first power mechanism, and an armature of the electromagnetic relay is arranged on the shift structure, so that the first worm can be switched between the driving mode and the shift mode through the electromagnetic relay.
It should be understood that although the number of the output units 111a, 111b, 111c, 111d, 111e, 111f, 111g, 111h, 111i, 111j is 10 in the above embodiment, there may be any number of the output units 111a, 111b, 111c, 111d, 111e, 111f, 111g, 111h, 111i, 111j in another embodiment. Further, it should be appreciated that in another embodiment, the first power structure 107 and the second power structure 109 may not be limited to being disposed at an intermediate position of the phaser actuator, and the first power structure 107 and the second power structure 109 may be disposed at any suitable location.
In the embodiment shown in fig. 1 to 7, the second power mechanism 109, such as a main motor, transmits power through a combination of a spur gear and a worm gear. In the embodiment shown in fig. 8 and 9, the difference from the embodiment shown in fig. 1 to 7 is that the rack gear of the shifter transmission 200 that meshes with the first power mechanism 207 is disposed in a direction parallel to the axial direction of the main shaft. Accordingly, the direction of the gear driven by the first power mechanism 207 through the transmission shaft is adjusted accordingly. The second power mechanism 209 omits a transmission structure of a straight rack and a worm gear, and the motor rotates to directly drive the helical gear to rotate so as to drive the output unit to move. In another embodiment, the second power mechanism 209 may also transmit power via bevel gear engagement to drive the output unit.
In the embodiment shown in fig. 10, a plurality of elastic auxiliary elements (e.g., springs) 301 may also be provided on the shift structure 105 to prevent the rack 105a on the shift structure from interfering with the worms 104a, 104 b. It should be understood that in another embodiment, the main shaft 103 may also be disposed on the sub-housing 101 a. In another embodiment, the sub-housing 101a and the sub-housing 101b may be integrally formed.
