Automotive actuators are small components of intelligent electronic control systems that can convert control signals from ECU (automotive electronic control unit) into mechanical or electrical movements to complete control functions and achieve required movements and actions. For example, the shift actuator of an automatic transmission can drive the transmission shift fork to rotate according to electrical signal instructions to achieve shifting actions by attaching a shift actuator to the transmission. There are more and more actuators on cars, such as rearview mirror folding and electric seat adjustment, which are becoming more and more intelligent and humanized. As an action element and execution unit of the electronic control system, the actuator reflects the unstoppable development of automobile intelligence and electrification from a tiny point.

[0003] In the use of existing actuators and controllers, the core reduction mechanism usually uses a motor to directly drive the gear assembly, and then drives the sun gear in the planetary gear assembly to move. The reduction ratio is relatively small, and the motor power requirement is high, which limits the selection of the motor. At the same time, there are few reports on the market about the integration of the actuator controller for double fork shifting.

[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0034] See also Figure 1-Figure 8 In this embodiment, a double-shift fork gear selection and shifting execution transmission device for an automobile transmission relates to the technical field of automobile actuators. Two planetary gear parts 20 are relatively installed on two inner rings 11 of a planetary gear ring support 10, and the two driving parts 21 are synchronously turned through a transmission component 22, so that the two driving parts 21 are arranged side by side on the same side of the planetary gear ring support 10 perpendicular to the axial direction, so as to realize the double-shift fork gear shifting of the automobile transmission while improving the compactness of the structure and achieving a better reduction ratio performance.

[0035] like Figure 1-Figure 4As shown, the automobile transmission double shift fork gear selection and shifting execution transmission device includes a planetary gear ring support 10 and two planetary gear parts 20. The planetary gear ring support 10 is recessed inward on opposite sides to form two inner gear rings 11. The two planetary gear parts 20 correspond to the two inner gear rings 11 and are movably arranged on the corresponding inner gear rings 11.

[0036] See also Figure 7 The planetary gear unit 20 includes a driving member 21, a transmission assembly 22 and a planetary gear train 23. The planetary gear train 23 is arranged in the inner gear ring 11. The planetary gear train 23 includes a planet carrier 231, at least one planetary gear 232 and a sun gear 233. The planet carrier 231 is provided with a lever 2311 and is coaxially arranged with the inner gear ring 11. The planetary gear 232 is rotatably mounted on the planet carrier 231. Both sides of the planetary gear 232 are respectively meshed with the inner gear ring 11 and the sun gear 233. The driving member 21 is connected to the corresponding sun gear 233 through the corresponding transmission assembly 22 to drive the corresponding sun gear 233 to rotate. The transmission assembly 22 is used to increase the reduction ratio. The two driving members 21 are arranged side by side on the same side of the planetary gear ring support 10 perpendicular to the axial direction.

[0037] The utility model is a transmission device for executing gear selection and shifting of a double shift fork of an automobile gearbox. Two inner gear rings 11 are formed on opposite sides of a planetary gear ring support 10. Two planetary gear parts 20 correspond to the two inner gear rings 11 and are movably arranged on the corresponding inner gear rings 11. A driving member 21 is connected to a corresponding sun gear 233 via a corresponding transmission assembly 22 to drive the corresponding sun gear 233 to rotate. The transmission assembly 22 can adopt a meshing worm wheel 221 and a worm 222 to improve the reduction ratio. The above-mentioned structural layout mode realizes that the two driving members 21 are arranged side by side on the same side of the planetary gear ring support 10 to optimize the spatial layout and further improve the compactness of the structure. Two sets of structures can be arranged at the same time. The transmission device cooperates with the two shift forks of the gearbox to realize the separate or combined action of the two shift forks of the gearbox.

[0038] In this embodiment, the transmission assembly 22 includes a meshing worm wheel 221 and a worm 222, the driving member 21 is a motor, the driving end of the motor is fixedly connected to the worm 222, and one side of the sun gear 233 is fixedly connected to the worm wheel 221. As a preferred embodiment, the worm wheel 221 is a fan-shaped worm wheel 221, and the sun gear 233 is integrally formed at the rotating shaft end of the worm wheel 221. This transmission method can improve the reduction ratio, and at the same time, two motors are arranged side by side on the same side of the planetary gear ring support 10 perpendicular to the axial direction, which can reduce the space occupation compared to other transmission methods arranged on the opposite side. As a preferred embodiment, the worm gears 222 fixedly connected to the driving ends of the two motors are arranged in parallel, and the two fan-shaped worm wheels 221 are correspondingly arranged above the two worm gears 222, and the axes of the two are perpendicular to each other, so as to realize steering transmission. Since the fan-shaped worm wheel 221 reduces the material usage and volume size compared with the circular worm wheel 221, the corresponding fan-shaped size can be set based on the rotation stroke requirement of the fan-shaped worm wheel 221, thereby reducing the volume of the overall structure of the automobile transmission double-shift fork gear selection and shifting execution transmission device and realizing a compact internal structure.

[0039] It can be understood that the planetary gear ring support 10 is fixed with a fixed shaft 12 corresponding to the axis of the inner gear ring 11, and the planetary carrier 231 and the lever 2311 are integrally formed, which improves the stability of the lever 2311 and avoids the risk of breakage of the rear connection. Figure 4 The planet carrier 231 includes a rotating disk 2312 and a rotating shaft 2313. The fixed shaft 12 is rotatably connected to the rotating disk 2312 and the sun gear 233. The rotating shaft 2313 is eccentrically arranged relative to the fixed shaft 12 and is fixedly connected to the rotating disk 2312. The rotating shaft 2313 is rotatably connected to the planet gear 232. The fixed shaft 12 is used to connect to the external housing 30. In some embodiments, fixed seats 31 are arranged at intervals on opposite sides of the mounting cavity at the top of the housing 30. The fixed seats 31 are detachably connected to the ends of the fixed shaft 12 so that two planetary gear units 20 can be cantilevered and mounted in the mounting cavity. Among them, compared with the existing technology, in which the fixed shaft 12 is fixedly connected to the planet carrier 231, which will cause the fixed shaft 12 and the planet carrier 231 to rotate synchronously, and an external structure needs to be added to fix the relative position of the planetary gear ring support 10 and the housing 30, the present application adopts a fixed shaft 12 and the rotating disk 2312 and the sun gear 233 to be rotatably connected, so that the fixed shaft 12 can be fixed to the housing 30. Compared with the connection method of the existing technology in which the fixed shaft 12 is rotatably connected to the housing 30, it is easy to disassemble, simplifies the structure, and reduces the volume of the structure. The above structure drives the worm 222 through the driving member 21, drives the worm wheel 221, thereby realizing the rotation of the sun wheel 233, and the sun wheel 233 then drives the planetary wheel 232 to rotate, thereby driving the rotating disk 2312 to rotate as a whole, and the lever 2311 is fixed to the outer ring of the rotating disk 2312 to complete the transmission of power.

[0040] Furthermore, the inner gear ring 11 is provided with a notch 111, and the lever 2311 is movably disposed in the notch 111 and partially extends out of the notch 111. This arrangement, on the one hand, allows the notch 111 to facilitate the extension of the lever 2311 to cooperate with the shift fork of the external gearbox, and avoids the extension of the lever 2311 by increasing the thickness of the rotating disk 2312. In other words, the notch 111 can reduce the volume of the structure, and on the other hand, the notch can limit the movement of the lever 2311, thereby improving safety.

[0041] In this embodiment, the axis of the worm wheel 221 is arranged perpendicular to the axis of the worm 222, which can reduce the volume, optimize the structural layout, and facilitate maintenance. In practical applications, the two planetary gear parts 20 are symmetrically arranged in the corresponding inner gear ring 11.

[0042] See also Figure 1-Figure 8 The present invention also provides a dual-shift fork gear selection and shift execution controller for an automobile transmission, including a dual-shift fork gear selection and shift execution transmission device for an automobile transmission, and also includes:

[0044] The two induction magnets 40 are fixed on the planet carrier 231 .

[0045] Two Hall sensors 50 are disposed in the housing 30 and are arranged opposite to the corresponding induction magnets 40.

[0047] The housing 30 is provided with an installation cavity for installing the automobile gearbox double shift fork gear selection and shift execution transmission device at the top, so as to realize the assembly of the double shift fork gear selection and shift execution transmission device. The two drive member 21 installation openings realize that the drive ends of the two drive members 21 can extend to the installation cavity through the drive member 21 installation openings, and the drive ends of the drive members 21 and the sun gear 233 can cooperate with each other in the installation cavity through the transmission device. Based on the synchronous rotation of the planet carrier 231 and the induction magnet 40, the position of the shift rod 2311 is changed, so that it is sensed by the Hall sensor 50, and the controller on the PCBA mainboard 60 obtains the position of the induction magnet 40 to identify the magnetic field information of each position of the shift rod 2311 and the shift fork.

[0048] Furthermore, it also includes a side cover 33 and a bottom cover 34, the side cover is arranged corresponding to the contour of the driver 21 extending out of the installation opening of the driver 21, and is detachably connected to the housing 30 to fasten the two drivers 21. The above structure protects the driver 21 and reduces the noise generated by the driver 21. The bottom cover 34 is detachably connected to the housing 30 and forms an installation space for the PCBA mainboard 60 between the housing 30. The installation space is spaced apart from the installation cavity, so that the installation space and the installation cavity are not connected to each other and are not contaminated by grease, impurities, etc. of the transmission system.

[0049] For practical applications, please refer to Figure 3 The planetary gear ring support 10 is provided with a positioning groove in the middle of the bottom surface, and the installation cavity of the housing 30 is formed with a positioning column 301 corresponding to the positioning groove, so that the planetary gear ring support 10 can be assembled with the housing 30 along the direction of the positioning column to achieve rapid installation of the two. The planetary gear ring support 10 is also provided with bosses 101 at opposite ends along the axial direction, and the installation cavity is formed with a seating groove 302 corresponding to the boss 101. When the boss contacts the seating groove 302, it is locked by bolts to achieve a detachable connection between the planetary gear ring support 10 and the housing 30.

[0050] Workflow: Assemble the planet carrier onto the fixed shaft 12, then install the planetary gear 232, then assemble the sun gear 233 and the worm gear 221, assemble this transmission with the inner gear ring into an assembly and then assemble it into the housing, finally assemble the motor and the worm, and the worm automatically meshes with the worm gear during the assembly process. Specifically, the sun gear 233 is integrally formed with the worm gear 221 or the worm gear 221 fastened to the sun gear 233, the corresponding induction magnet 40 is pre-installed on the turntable 2312, the planet carrier is assembled to the fixed shaft 12, and then the various components of the planetary gear system 23 are assembled in sequence, the planet carrier 231 is located in the inner gear ring 11, each planetary gear 232 is rotatably mounted on the planet carrier 231 and meshes with the corresponding sun gear 233 and the inner gear ring 11 respectively, the sun gear 233 is located at the center of the inner gear ring 11, and multiple planetary gears 232 are arranged at intervals along the circumference of the sun gear 233, so that each set of sun gears 233 and planetary gears 232 mesh with each other and can transmit to each other, at this time, the planetary gear system and the planetary gear ring support 10 are assembled into an assembly. The worm and the motor are assembled, and the two motors are installed from the installation openings of the two drive members 21, so that the driving ends of the two drive members 21 can extend to the installation cavity through the installation openings of the drive member 21, and the worm automatically meshes with the worm during the assembly process. The sun gear 233 moves synchronously with the worm gear 221, and the axis of the worm gear 221 is arranged perpendicular to the axis of the worm 222, and then the planetary gear ring support 10 and the housing 30 are fixed. Since one end of the lever 2311 is integrally formed with the planetary carrier 231, the end that exceeds the inner gear ring 11 is assembled and connected with the gearbox shift fork. The motor drives the worm gear 221 assembly and the planetary gear train 23 in turn, thereby driving the planetary carrier 231 to rotate. The planetary carrier 231 turns forward or reverse with the forward and reverse rotation of the motor, and the lever 2311 integrated with the planetary carrier 231 drives the shift fork to move to select and shift gears.

It can be seen that the driving end of the driving member 21 and the sun gear 233 can cooperate with each other in the installation cavity through the transmission device, thereby driving the lever 2311 to rotate to drive the gear shift fork of the gearbox to perform gear switching, so as to realize the separate or combined action of the two gear shift forks of the gearbox. Based on the synchronous rotation of the planet carrier 231 and the induction magnet 40, the position of the lever 2311 is changed, so that it is sensed by the Hall sensor 50, and the controller on the PCBA mainboard 60 obtains the position of the induction magnet 40 to identify the magnetic field information of each position of the lever 2311 and the gear shift fork 70.
