Technical Field

[0001] The invention relates to the field of mechanical transmission control, and in particular to a transmission shifting device and a vehicle. Background Art

[0002] In order to meet the engine power and gear shifting comfort, manual commercial vehicle transmissions reduce the speed ratio difference between gears and increase the speed ratio of low gears to meet the vehicle's climbing and power performance. Therefore, multi-speed will be the development direction of manual transmissions. The current commercial vehicle transmissions are generally 5-speed or 6-speed structures. The corresponding relationship between the gears and the gear slots is as follows: Figure 1 and Figure 2 As shown, when there are 8 or more gears, the existing structure will have overlapping gear arrangements, or even if the gears are overlapping, there will be insufficient gears, and the chaotic gear sequence will easily affect the accuracy of the driver's gear selection and shifting. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention is to provide a transmission shifting device.

[0005] To this end, a second aspect of the present invention is to provide a vehicle.

[0006] In view of this, the first aspect of the present invention proposes a transmission shift device, including: a shell, a plurality of gear slots are arranged on the shell, each gear slot corresponds to two gears; a shift shaft, installed on the shell and capable of axially moving relative to the shell, the shift shaft being provided with a protrusion structure along the circumferential direction; a shift head, connected to the shift shaft and driving the shift shaft to switch gears; an elastic positioning seat, installed on the shell, arranged opposite to the protrusion structure and capable of abutting against the protrusion structure; a limit assembly, arranged on the shell and the shift shaft, the limit assembly limits the shift shaft and the shell; wherein the shift head drives the shift shaft to move axially, and the relative position of the protrusion structure and the elastic positioning seat is limited by the elastic positioning seat and the limit assembly, thereby adjusting the shift head to correspond to the plurality of gear slots for shifting.

[0007] The transmission shift device provided by the present invention comprises a housing, a shift shaft, a shift dial head, an elastic positioning seat and a limit assembly. The housing is provided with a plurality of gear slots, each gear slot corresponds to two gears, the shift shaft and the elastic positioning seat are installed on the housing, the shift shaft is circumferentially provided with a protrusion structure that can abut against the elastic positioning seat, and the limit assembly is arranged on the housing and the shift shaft, and the shift dial head drives the shift shaft to move axially relative to the housing, and the relative position of the protrusion structure and the elastic positioning seat is limited by the elastic positioning seat and the limit assembly, so as to adjust the shift dial head to correspond to the plurality of gear slots and make the shift shaft and the housing limit multiple times for shifting, thereby avoiding the situation that the existing structure sets multiple gears and there are insufficient gears, and at the same time avoiding the problem that the gears are unclear and the gear sequence is chaotic due to the overlapping arrangement of gears in the existing structure, effectively improving the accuracy of the driver's gear selection, and improving the gear shifting efficiency and the accuracy of the gear shifting, thereby improving the user's driving experience and improving the market competitiveness of the product.

[0008] Furthermore, by arranging multiple gear slots on the housing, each gear slot corresponds to two gears, so that the shift head drives the shift shaft to move axially relative to the housing, and the relative position of the protruding structure and the elastic positioning seat is limited by the elastic positioning seat and the limiting assembly, so that the shift shaft is limited with the housing multiple times, and then the shift head corresponds to the multiple gear slots in sequence, thereby realizing the multi-speed function of the transmission, and each gear slot corresponds to two gears, avoiding the overlapping arrangement of gears in the prior art so that one gear slot corresponds to more than two gears and the gear sequence is confused. Each gear slot corresponds to two gears, which effectively ensures a reasonable gear sequence and a clear gear number, and facilitates the driver to quickly, conveniently and accurately complete the gear selection and shifting actions, thereby improving the user's driving experience, and at the same time avoiding safety accidents or damage to transmission components caused by incorrect gear selection and gear shifting operations, effectively improving the safety and reliability of the product, and improving the market competitiveness of the product. It can be understood that the two gears in each gear slot are arranged relative to each other in a direction perpendicular to the direction of the movement trajectory of the shift head when the shift head drives the shift shaft to move axially. For example, if the shift head moves in the horizontal direction to limit the shift shaft and the housing, the two gears in each gear slot are arranged in the vertical direction, and then after the shift head moves in the horizontal direction to limit the shift shaft and the housing, the shift is completed by adjusting the shift head in the vertical direction to correspond to a gear in the gear slot. It can also be understood that the two gears in each gear slot can be arranged in other ways as long as they meet the requirements.

[0009] Furthermore, the number of gear slots can be reasonably set according to the needs to meet the needs of different numbers of gears, and the application range is wide. It can be understood that 5 gear slots can be set, of which 4 gear slots are respectively set for the first and second gears, the third and fourth gears, the fifth and sixth gears, the seventh and eighth gears, and the remaining gear slot is set for the R gear, which can realize the arrangement of the eight gears of the transmission, and the gears are clear and orderly, and there is only one or two gears in each gear slot, which is convenient for users to accurately select and shift gears, and improve the shifting quality of the transmission.

[0010] Furthermore, by arranging a protruding structure on the circumference of the shift shaft and arranging a limit assembly on the housing and the shift shaft, the shift head drives the shift shaft to move axially relative to the housing, and the relative position of the protruding structure and the elastic positioning seat is limited by being installed on the elastic positioning seat and the limit assembly, the shift head is adjusted to correspond to multiple gear slots and the shift shaft and the housing are limited multiple times for shifting, so that a multi-gear arrangement of the transmission can be achieved through a simple structure, and the structure is reasonable and easy to implement, which effectively improves the market competitiveness of the product.

[0013] In this technical solution, the raised structure includes a first side surface and a second side surface distributed along the axial direction of the shift shaft. The axial distance of the shift shaft moving from the first side surface abutting against the elastic positioning seat to the second side surface abutting against the elastic positioning seat is d1, and the distance between the center lines of the two gear slots located in the middle is d2. By d1=d2, the gears corresponding to the number of gears located in the middle part are respectively abutted by the first side surface and the elastic positioning seat, thereby distinguishing between high gear and low gear, that is, the shift shaft continues to move in the direction of the second side surface from the first side surface abutting against the elastic positioning seat and the shift shaft continues to move in the direction of the first side surface from the second side surface abutting against the elastic positioning seat, respectively, which can select low gear and high gear, and plays a certain prompting role, which is conducive to users to quickly and accurately select low gear and high gear, improve the user's shifting efficiency and accuracy, and enhance the user's usage experience.

At the same time, it avoids the problem of unclear gears and chaotic gear sequence caused by the overlapping arrangement of gears in the existing structure, effectively improving the accuracy of the driver's gear selection, and improving the gear shifting efficiency and accuracy.

[0018] In the above technical solution, preferably, the guide part includes: two spacers; an elastic member, which is sleeved on the outside of the shift shaft, and both ends of the elastic member are respectively abutted against the shift shaft through a spacer; wherein the axial movement of the shift shaft makes the two spacers respectively adapt to the multiple positioning parts for limiting.

[0019] In this technical solution, the guide portion includes two spacers and an elastic member, which is sleeved on the outside of the shift shaft. Both ends of the elastic member are respectively in contact with the shift shaft through a spacer. The two spacers are respectively matched with multiple positioning portions for limiting through axial movement of the shift shaft, so that multiple limiting of the shift shaft and the housing and gear selection and shifting can be achieved through a simple structure. The cost is low and it is easy to implement, which effectively expands the scope of application. The two spacers and the elastic member are small in size, which can meet the limited internal space requirements of the transmission, further improving the scope of application of the product.

[0020] Furthermore, the guide part includes an elastic member and a spacer, and the axial movement of the shift shaft makes the two spacers respectively match with the multiple positioning parts for limiting, so that the elastic force of the elastic member and the elastic positioning seat are used to ensure the axial balance of the shift shaft during shifting, thereby improving the reliability of the product. The elastic member can be a spring or other elastic structure that meets the requirements.

[0021] In the above technical solution, preferably, the plurality of positioning portions include a hole retaining ring provided on the shell and adapted to the spacer.

[0023] Furthermore, the positioning portion is a retaining ring for a hole arranged on the shell, which has a simple structure, low processing cost, is easy to implement, and is conducive to reducing the manufacturing cost of the product.

[0024] In the above technical solution, preferably, the plurality of positioning portions further include a boss structure arranged inside the housing, and the boss structure is arranged along the circumferential direction of the shift shaft.

[0025] In this technical solution, multiple positioning parts include a boss structure arranged inside the shell, and the boss structure is arranged along the circumference of the shift shaft, so that the boss structure is adapted to the spacer, and the elastic force of the elastic member and the elastic positioning seat are used to ensure the axial balance of the shift shaft during gear shifting, thereby ensuring that the shift shaft and the shell are firmly limited when shifting gears, thereby improving the reliability of the product.

[0026] Furthermore, the positioning portion is a boss structure arranged on the shell, which has a simple structure, low processing cost, and is easy to implement, which is beneficial to reducing the manufacturing cost of the product. The boss structure is arranged along the circumference of the shift shaft, which effectively improves the reliability of the limiting of the guide portion and the positioning portion, ensuring that the shift shaft and the shell are stably limited when shifting gears, thereby improving the reliability of the product and improving the market competitiveness of the product.

[0027] In the above technical solution, preferably, the plurality of positioning parts include a boss structure and two hole retaining rings, and the boss structure is adjacent to the elastic positioning seat.

[0028] In this technical solution, multiple positioning parts include a boss structure and two hole retaining rings, and the boss structure is adjacent to the elastic positioning seat, so that multi-gear selection and shifting of the transmission can be achieved by matching the spacer with a boss structure and two hole retaining rings for limiting and cooperating with the elastic positioning seat and the raised structure for limiting. The structure is simple and easy to implement.

[0029] It is understandable that the number of boss structures and hole retaining rings can be set according to the different numbers of gear positions, and can be set according to the different structures of the housing and the different structures of the shift shaft, as long as the requirements are met.

[0030] In the above technical solution, preferably, the guide part also includes a shaft retaining ring installed on the shift shaft; the shift shaft is provided with a first step; one end of the elastic member abuts against the shaft retaining ring through a spacer, and the other end of the elastic member abuts against the first step through a spacer.

[0031] In this technical solution, the guide part also includes a shaft retaining ring installed on the shift shaft, the shift shaft is provided with a first step, one end of the elastic member is in contact with the shaft retaining ring through a spacer, and the other end of the elastic member is in contact with the first step through a spacer, so that the elastic member limits the two spacers between the shaft retaining ring and the first step, effectively increasing the telescopic stroke of the elastic member, thereby facilitating the spacers to adapt to the multiple positioning parts for limiting when the shift shaft moves, and facilitating the realization of the multi-gear function of the transmission. At the same time, the spacers are limited at both ends of the elastic member by the shaft retaining ring and the first step, which is simple in structure, easy to implement, low in cost, and conducive to product promotion.

[0032] In the above technical solution, preferably, the shift shaft is further provided with a second step, and the second step and the first step are respectively located on both sides of the protruding structure; wherein the axial movement of the shift shaft causes the elastic positioning seat to abut against the second step.

[0033] In this technical solution, the shift shaft is provided with a second step, and the second step and the first step are respectively located on both sides of the raised structure. The elastic positioning seat is abutted against the second step by the axial movement of the shift shaft, which further increases the number of times the shift shaft and the housing are limited, which is conducive to setting a larger number of gears in the transmission, and is conducive to realizing a multi-gear arrangement of the transmission, thereby improving the market competitiveness of the product. Furthermore, by increasing the number of times the shift shaft and the housing are limited by abutting against the second step provided on the shift shaft and the elastic positioning seat, the structure of the shift shaft itself is effectively utilized, the product structure is simplified, the manufacturing cost is reduced, and the market competitiveness of the product is improved.

[0034] In the above technical solution, preferably, the second step is a chamfered structure; and the first side surface and the second side surface are inclined surfaces.

[0035] In this technical solution, the second step is a chamfered structure, so that when the shift shaft is subjected to a preset axial force during movement, the elastic positioning seat passes over the second step along the chamfered structure, avoiding the shift shaft from getting stuck when the side of the second step is a plane, effectively improving the flexibility of the shift shaft in shifting, thereby enhancing the user's driving experience.

[0036] The first side surface and the second side surface are inclined surfaces, so that when the shift shaft is subjected to a preset axial force during movement, the elastic positioning seat passes over the raised structure along the inclined surface, thereby avoiding the shift shaft from getting stuck when the first side surface and the second side surface are flat surfaces, effectively improving the flexibility of the shift shaft in shifting, thereby enhancing the user's driving experience.

[0037] Furthermore, the chamfered structure, the first side surface and the second side surface have relatively large slope angles, which can further enhance the axial force and facilitate the flexible and stable movement of the shift shaft, thereby improving the sensitivity and accuracy of the shift.

[0038] In the above technical solution, preferably, there are two elastic positioning seats, and the two elastic positioning seats are symmetrically arranged on the housing along the circumference of the shift shaft.

[0039] In this technical solution, there are two elastic positioning seats, which are symmetrically arranged on the housing along the circumference of the shift shaft. The shift shaft is limited by the two elastic positioning seats, which effectively improves the stability of the shift shaft and the housing when limited, thereby improving the reliability of the product.

[0040] In the above technical solution, preferably, the elastic positioning seat includes a positioning ball head, and the shift shaft moves axially so that the positioning ball head abuts against the protruding structure and the second step respectively.

[0041] In this technical solution, the elastic positioning seat includes a positioning ball head, and the axial movement of the shift shaft causes the positioning ball head to abut against the raised structure and the second step respectively. Since the positioning ball head is a smooth spherical structure, when the shift shaft is subjected to a preset axial force during movement, it can pass through the raised structure and the second step quickly and smoothly, thereby improving the sensitivity of gear selection and shifting, and thereby enhancing the user's driving experience.

[0042] A second aspect of the present invention provides a vehicle, comprising a transmission shifting device as described in any technical solution of the first aspect.

[0043] The vehicle provided by the present invention includes a transmission shifting device as described in any one of the first aspects, and therefore has all the beneficial effects of the above-mentioned transmission shifting devices, which will not be described one by one here.

[0044] In a specific embodiment, a transmission shift device includes a shift, a shift shaft, a housing, an elastic positioning seat, a first spacer, a second spacer, a spring, a shaft retaining ring, a first hole retaining ring, and a second hole retaining ring. The shift dial is rigidly connected to the shift shaft, the housing supports the shift shaft, and the shift shaft can slide axially. The elastic positioning seat is installed on the housing, and the first spacer and the second spacer are arranged at both ends of the spring. Under the action of the spring force, the first spacer is compressed to the first step of the shift shaft, and the second spacer is compressed to the shaft washer of the shift shaft. When the shift shaft slides to the left, the first spacer is limited by the housing and cannot continue to move, compressing the spring so that the shift shaft is subjected to the spring force to the right. At this time, the raised structure of the shift shaft passes over the elastic positioning seat. The shift seat makes the second side face act on the positioning ball head. Under the elastic force of the elastic positioning seat, the shift shaft is subjected to an axial force to the left. In the absence of other external forces, the shift shaft can be balanced in axial force to ensure that the shift head corresponds to the 5 / 6 gear slot of the transmission, and the 5 / 6 gear shift operation can be performed; when the shift shaft continues to move left, the second spacer and the first hole on the inner side of the housing are limited by a retaining ring. At this time, the shift head moves to the gear slot corresponding to the 7 / 8 gear of the transmission, and the 7 / 8 gear shift operation can be performed. Similarly, if Figure 2 As shown, the shift shaft moves to the right, and the second spacer and the second hole are limited by the retaining ring to generate an axial force to the left, and the elastic locating seat acts on the first side of the shift shaft to generate an axial force to the right. At this time, the axial force of the shift shaft is balanced, and the shift head stays in the 3 / 4 gear slot, and the 3 / 4 gear shift operation can be performed; the shift shaft continues to move to the right, and the locating ball head of the elastic locating seat contacts the second step of the shift shaft, and the axial force will increase significantly. Here, the shift head corresponds to the 1 / 2 gear slot; the shift shaft continues to move to the right, and the locating ball head passes over the second step, and the first spacer contacts the first hole on the inner side of the shell and is limited by the retaining ring. At this time, the shift head stays in the R gear slot, and the R gear operation can be performed.

[0045] Furthermore, the transmission shift device allows the shift shaft to be freely positioned in the 3rd / 4th gear or the 5th / 6th gear, and can be axially limited in the 7th / 8th gear or the R gear. In the 1st / 2nd gear, the axial force increases significantly when moving to the R gear, which plays a certain prompting role, thereby improving the accuracy of gear selection and shifting, and enhancing the driving experience of the user. At the same time, during the movement of the shift shaft, under the action of the compression force of the elastic positioning seat and the axial force of the spring, the shift shaft is limited and balanced with the housing on the first side and the second side of the convex structure, and the gear is divided into two sections. The second side and its right side can be arranged with 5th, 6th, 7th, and 8th gears, and the first side and its left side can be arranged with 1st, 2nd, 3rd, 4th, and R gears; when the positioning seat ball head is positioned on the second side, it is ensured that the shift dial head can work in the 5th / 6th gear slot, and when the positioning seat ball head is positioned on the first side, it is ensured that the shift dial head can work in the 3rd / 4th gear slot; when the shift shaft moves to the left or right, the spacers at both ends will be limited with the middle hole by the retaining ring, thereby realizing the shifting of other gear slots. The transmission shifting device of the present invention is conducive to the driver to select and shift gears accurately and clearly, and the gear selection limit is reliable, which effectively improves the shifting quality of the transmission and further improves the user's driving experience.

[0061] The transmission shift device 100 provided by the present invention includes a housing 12, a shift shaft 14, a shift head 18, an elastic positioning seat 16 and a limit assembly. The housing 12 is provided with a plurality of gear slots, each gear slot corresponds to two gears, the shift shaft 14 and the elastic positioning seat 16 are installed on the housing 12, the shift shaft 14 is provided with a convex structure 142 that can abut against the elastic positioning seat 16 along the circumferential direction, the limit assembly is arranged on the housing 12 and the shift shaft 14, the shift head 18 drives the shift shaft 14 to move axially relative to the housing 12, and the elastic positioning seat 16 is used to prevent the gear shaft 14 from moving axially. The seat 16 and the limit assembly define the relative position of the protruding structure 142 and the elastic positioning seat 16, thereby adjusting the shift knob 18 to correspond to multiple gear slots and limiting the shift shaft 14 and the housing 12 for multiple shifting, thereby avoiding the problem of insufficient gears due to multiple gears in the existing structure, and at the same time avoiding the problem of unclear gears and chaotic gear sequence due to overlapping gear arrangements in the existing structure, effectively improving the accuracy of the driver's gear selection, and improving the gear shifting efficiency and accuracy, thereby enhancing the user's driving experience and improving the market competitiveness of the product.

[0062] Furthermore, by providing a plurality of gear slots on the housing 12, each gear slot corresponds to two gears, so that the shift head 18 drives the shift shaft 14 to move axially relative to the housing 12, and the relative position of the protruding structure 142 and the elastic positioning seat 16 is limited by the elastic positioning seat 16 and the limiting assembly, so that the shift shaft 14 is limited by the housing 12 multiple times, and then the shift head 18 corresponds to the plurality of gear slots in sequence, thereby realizing the multi-speed function of the transmission, and each gear slot corresponds to two gears, avoiding the overlapping arrangement of gears in the prior art so that one gear slot corresponds to more than two gears and the gear sequence is confused, and each gear slot corresponds to two gears, which effectively ensures a reasonable gear sequence and a clear gear number, and facilitates the driver to quickly, conveniently and accurately complete the gear selection and shifting actions, thereby improving the user's driving experience, and at the same time avoiding safety accidents or damage to transmission components caused by incorrect gear selection operations and gear shifting errors, thereby effectively improving the safety and reliability of the product and improving the market competitiveness of the product. It can be understood that the two gears in each gear slot are arranged relative to each other in a direction perpendicular to the direction of the movement trajectory of the shift head when the shift head drives the shift shaft 14 to move axially. For example, if the shift head moves in the horizontal direction to limit the shift shaft 14 and the housing 12, the two gears in each gear slot are arranged in the vertical direction, and then the shift head moves in the horizontal direction to limit the shift shaft 14 and the housing 12, and the shifting is completed by adjusting the shift head in the vertical direction to correspond to a gear in the gear slot. It can also be understood that the two gears in each gear slot can be arranged in other ways as long as they meet the requirements.

[0063] Furthermore, the number of gear slots can be reasonably set according to the needs to meet the needs of different numbers of gears, and the application range is wide. It can be understood that 5 gear slots can be set, of which 4 gear slots are respectively set for the first and second gears, the third and fourth gears, the fifth and sixth gears, the seventh and eighth gears, and the remaining gear slot is set for the R gear, which can realize the arrangement of the eight gears of the transmission, and the gears are clear and orderly, and there is only one or two gears in each gear slot, which is convenient for users to accurately select and shift gears, and improve the shifting quality of the transmission.

[0064] Furthermore, by arranging a protruding structure 142 on the circumference of the shift shaft 14 and arranging a limiting assembly on the housing 12 and the shift shaft 14, the shift head 18 drives the shift shaft 14 to move axially relative to the housing 12, and the relative position of the protruding structure 142 and the elastic positioning seat 16 is limited by being installed on the elastic positioning seat 16 and the limiting assembly, so that the shift head 18 is adjusted to correspond to multiple gear slots and the shift shaft 14 and the housing 12 are limited multiple times for shifting, so that a multi-gear arrangement of the transmission can be achieved through a simple structure, and the structure is reasonable and easy to implement, which effectively improves the market competitiveness of the product.

[0065] like Figure 3 and Figure 5 As shown, in one embodiment of the present invention, preferably, the protruding structure 142 includes a first side surface 1422 and a second side surface 1424 distributed along the axial direction of the shift shaft 14; the axial distance of the shift shaft 14 moving from the first side surface 1422 abutting against the elastic positioning seat 16 to the second side surface 1424 abutting against the elastic positioning seat 16 is d1; the distance between the center lines of the two gear slots located in the middle is d2; wherein, d1=d2.

[0066] In this embodiment, the protruding structure 142 includes a first side surface 1422 and a second side surface 1424 distributed along the axial direction of the shift shaft 14.

By d1=d2, the first side surface 1422 abutting against the elastic positioning seat 16 and the second side surface 1424 abutting against the elastic positioning seat 16 correspond to the gear slots located in the middle. The gear positions of the number of gears can be distinguished from the high gear and the low gear, that is, the shift shaft 14 continues to move along the direction of the second side 1424 by abutting the first side 1422 with the elastic positioning seat 16 and the shift shaft 14 continues to move along the direction of the first side 1422 by abutting the second side 1424 with the elastic positioning seat 16, which can respectively select the low gear and the high gear, which plays a certain prompting role, is conducive to the user to quickly and accurately select the low gear and the high gear, improve the user's shifting efficiency and accuracy, and enhance the user's usage experience.

The plurality of positioning portions are axially arranged on the housing 12 along the shift shaft 14 and are located on one side of the elastic positioning seat 16. The guiding portion is arranged on the shift shaft 14 and corresponds to the plurality of positioning portions. The shift shaft 14 is axially moved so that the guiding portion is respectively matched with the plurality of positioning portions for limiting. The multi-gear function of the transmission can be realized, and each gear slot corresponds to two gears, thereby avoiding the situation in which the existing structure sets multiple gears and there are insufficient gears. At the same time, the problem in the existing structure that the gears are arranged in an overlapping manner, resulting in unclear gears and chaotic gear sequences, is avoided, thereby effectively improving the accuracy of the driver's gear selection, and improving the gear shifting efficiency and accuracy.

[0071] like Figure 3 and Figure 5 As shown, in one embodiment of the present invention, preferably, the guide portion includes: two spacers; an elastic member 24, which is sleeved on the outer side of the shift shaft 14, and both ends of the elastic member 24 are respectively abutted against the shift shaft 14 through a spacer; wherein the axial movement of the shift shaft 14 enables the two spacers to respectively adapt to the multiple positioning portions for limiting.

[0072] In this embodiment, the guide portion includes two spacers and an elastic member 24. The elastic member 24 is sleeved on the outside of the shift shaft 14. The two ends of the elastic member 24 are respectively abutted against the shift shaft 14 through a spacer. The two spacers are respectively matched with multiple positioning portions for limiting through the axial movement of the shift shaft 14, so that multiple limiting of the shift shaft 14 and the housing 12 and gear selection and shifting can be achieved through a simple structure. The cost is low and it is easy to implement, which effectively expands the scope of application. In addition, the two spacers and the elastic member 24 are small in size, which can meet the limited internal space requirements of the transmission, further improving the scope of application of the product.

[0073] Furthermore, the guide part includes an elastic member 24 and a spacer, and the shift shaft 14 moves axially so that the two spacers are respectively matched with the multiple positioning parts for limiting, so that the elastic force of the elastic member 24 and the elastic positioning seat 16 are used to ensure the axial balance of the shift shaft 14 during shifting, thereby improving the reliability of the product. The elastic member 24 can be a spring or other elastic structure that meets the requirements.

[0074] In one embodiment of the present invention, preferably, the plurality of positioning portions include a hole retaining ring disposed on the housing 12 and adapted to the spacer.

[0075] In this embodiment, multiple positioning parts include a hole retaining ring arranged on the shell 12 and adapted to the spacer, so that the hole retaining ring is adapted to the spacer, and the elastic force of the elastic member 24 and the elastic positioning seat 16 are used to ensure the axial balance of the shift shaft 14 during gear shifting, thereby ensuring that the shift shaft 14 and the shell 12 are firmly limited when shifting gears, thereby improving the reliability of the product.

[0076] Furthermore, the positioning portion is a retaining ring for a hole provided on the housing 12, which has a simple structure, low processing cost, and is easy to implement, thus helping to reduce the manufacturing cost of the product.

[0077] like Figure 3 and Figure 5 As shown, in one embodiment of the present invention, preferably, the plurality of positioning portions further include a boss structure disposed inside the housing 12 , and the boss structure is disposed along the circumference of the shift shaft 14 .

[0078] In this embodiment, the plurality of positioning portions include a boss structure disposed inside the housing 12, and the boss structure is disposed along the circumference of the shift shaft 14 so as to be matched with the spacer, and the elastic force of the elastic member 24 and the elastic positioning seat 16 are utilized to ensure the axial balance of the shift shaft 14 during gear shifting, thereby ensuring that the shift shaft 14 and the housing 12 are firmly limited during gear shifting, thereby improving the reliability of the product.

[0079] Furthermore, the positioning portion is a boss structure arranged on the shell 12, which has a simple structure, low processing cost, and is easy to implement, which is beneficial to reducing the manufacturing cost of the product. The boss structure is arranged along the circumference of the shift shaft 14, which effectively improves the reliability of the limiting of the guide portion and the positioning portion, and ensures that the shift shaft 14 and the shell 12 are stably limited when shifting gears, thereby improving the reliability of the product and improving the market competitiveness of the product.

[0080] In one embodiment of the present invention, preferably, the plurality of positioning portions include a boss structure and two hole retaining rings, and the boss structure is adjacent to the elastic positioning seat 16 .

[0081] In this embodiment, the multiple positioning parts include a boss structure and two hole retaining rings, and the boss structure is adjacent to the elastic positioning seat 16, so that multi-gear selection and shifting of the transmission can be achieved by matching the spacer with a boss structure and two hole retaining rings for limiting and cooperating with the elastic positioning seat 16 and the raised structure 142 for limiting. The structure is simple and easy to implement.

[0082] It is understandable that the number of boss structures and hole retaining rings can be set according to the different numbers of gear positions and can be set according to the different structures of the housing 12 and the different structures of the shift shaft 14 as long as the requirements are met.

[0083] like Figure 3 and Figure 5 As shown, in one embodiment of the present invention, preferably, the guide portion also includes a shaft retaining ring 28 installed on the shift shaft 14; the shift shaft 14 is provided with a first step 144; one end of the elastic member 24 abuts against the shaft retaining ring 28 through a spacer, and the other end of the elastic member 24 abuts against the first step 144 through a spacer.

[0084] In this embodiment, the guide part also includes a shaft retaining ring 28 installed on the shift shaft 14, the shift shaft 14 is provided with a first step 144, one end of the elastic member 24 abuts against the shaft retaining ring 28 through a spacer, and the other end of the elastic member 24 abuts against the first step 144 through a spacer, so that the elastic member 24 limits the two spacers between the shaft retaining ring 28 and the first step 144, effectively increasing the telescopic stroke of the elastic member 24, thereby facilitating the spacers to adapt to the multiple positioning parts for limiting when the shift shaft 14 moves, and facilitating the realization of the multi-gear function of the transmission. At the same time, the spacers are limited at both ends of the elastic member 24 by the shaft retaining ring 28 and the first step 144, which is simple in structure, easy to implement, low in cost, and conducive to product promotion.

[0085] like Figure 3 and Figure 5As shown, in one embodiment of the present invention, preferably, the shift shaft 14 is further provided with a second step 146 , and the second step 146 and the first step 144 are respectively located on both sides of the protruding structure 142 ; wherein the axial movement of the shift shaft 14 causes the elastic positioning seat 16 to abut against the second step 146 .

[0086] In this embodiment, the shift shaft 14 is provided with a second step 146, and the second step 146 and the first step 144 are respectively located on both sides of the protruding structure 142. The elastic positioning seat 16 is abutted against the second step 146 by the axial movement of the shift shaft 14, which further increases the number of times the shift shaft 14 and the housing 12 are limited, which is conducive to setting a larger number of gears for the transmission, and is conducive to realizing a multi-gear arrangement of the transmission, thereby improving the market competitiveness of the product. Furthermore, by increasing the number of times the shift shaft 14 and the housing 12 are limited by the second step 146 provided on the shift shaft 14 abutting against the elastic positioning seat 16, the structure of the shift shaft 14 itself is effectively utilized, the product structure is simplified, the manufacturing cost is reduced, and the market competitiveness of the product is improved.

[0087] In one embodiment of the present invention, preferably, the second step 146 is a chamfered structure; the first side surface 1422 and the second side surface 1424 are inclined surfaces.

[0088] In this embodiment, the second step 146 is a chamfered structure, so that when the shift shaft 14 is subjected to a preset axial force during movement, the elastic positioning seat 16 passes over the second step 146 along the chamfered structure, thereby preventing the shift shaft 14 from getting stuck when the side of the second step 146 is a plane, effectively improving the flexibility of the shift shaft 14 in shifting gears, thereby enhancing the user's driving experience.

[0089] The first side surface 1422 and the second side surface 1424 are inclined surfaces, so that when the shift shaft 14 is subjected to a preset axial force during movement, the elastic positioning seat 16 passes over the protruding structure 142 along the inclined surface, thereby preventing the shift shaft 14 from getting stuck when the first side surface 1422 and the second side surface 1424 are flat surfaces, effectively improving the flexibility of the shift shaft 14 in shifting gears, thereby enhancing the user's driving experience.

[0090] Furthermore, the chamfered structure, the first side surface 1422 and the second side surface 1424 have relatively large slope angles, which can further increase the axial force and facilitate the flexible and stable movement of the shift shaft 14, thereby improving the sensitivity and accuracy of the shift.

[0091] In one embodiment of the present invention, preferably, there are two elastic positioning seats 16 , and the two elastic positioning seats 16 are symmetrically arranged on the housing 12 along the circumference of the shift shaft 14 .

[0092] In this embodiment, there are two elastic positioning seats 16, and the two elastic positioning seats 16 are symmetrically arranged in the housing 12 along the circumference of the shift shaft 14. The shift shaft 14 is limited by the two elastic positioning seats 16, which effectively improves the stability of the shift shaft 14 and the housing 12 when limited, thereby improving the reliability of the product.

[0093] In one embodiment of the present invention, preferably, the elastic positioning seat 16 includes a positioning ball head, and the shift shaft 14 moves axially so that the positioning ball head abuts against the protruding structure 142 and the second step 146 respectively.

[0094] In this embodiment, the elastic positioning seat 16 includes a positioning ball head, and the axial movement of the shift shaft 14 causes the positioning ball head to abut against the protruding structure 142 and the second step 146 respectively. Since the positioning ball head is a smooth spherical structure, when the shift shaft 14 is subjected to a preset axial force during movement, it can quickly and smoothly pass through the protruding structure 142 and the second step 146, thereby improving the sensitivity of gear selection and shifting, thereby enhancing the user's driving experience.

[0095] A second aspect of the present invention provides a vehicle, comprising a transmission shifting device 100 as described in any technical solution of the first aspect.

[0096] The vehicle provided by the present invention includes the transmission shift device 100 as described in any one of the first aspects, and thus has all the beneficial effects of the above-mentioned transmission shift device 100, which will not be described one by one here.

[0097] In a specific embodiment, the vehicle is a manual transmission vehicle, such as Figure 3 and Figure 5 As shown, the transmission shift device 100 includes a shifting shaft 14, a housing 12, an elastic positioning seat 16, a first spacer 222, a second spacer 224, a spring, a shaft retaining ring 28, a first hole retaining ring 262, and a second hole retaining ring 264. The shifting head 18 is rigidly connected to the shifting shaft 14, the housing 12 supports the shifting shaft 14, and the shifting shaft 14 can slide axially, the elastic positioning seat 16 is installed on the housing 12, and the first spacer 222 and the second spacer 224 are arranged at both ends of the spring. Under the action of the spring force, the first spacer 222 is compressed onto the first step 144 of the shifting shaft 14, and the second spacer 224 is compressed onto the shaft washer of the shifting shaft 14. Figure 3 and Figure 4As shown, after the shift shaft 14 slides to the left, the first spacer 222 is limited by the housing 12 and cannot move further, compressing the spring so that the shift shaft 14 is subjected to a spring force to the right. At this time, the protruding structure 142 of the shift shaft 14 passes over the elastic positioning seat 16, so that the second side surface 1424 acts on the positioning ball head. Under the elastic force of the elastic positioning seat 16, the shift shaft 14 is subjected to an axial force to the left. In the absence of other external forces, the shift shaft 14 can be subjected to axial force balance at this time, ensuring that the shift head 18 corresponds to the 5 / 6 gear slot of the transmission, and the 5 / 6 gear shift operation can be performed; when the shift shaft 14 continues to move to the left, the second spacer 224 and the first hole on the inner side of the housing 12 are limited by the retaining ring 262. At this time, the shift head 18 moves to the gear slot corresponding to the 7 / 8 gear of the transmission, and the 7 / 8 gear shift operation can be performed. Similarly, Figure 5 and Figure 6 As shown, the shift shaft 14 moves to the right, and the second spacer 224 and the second hole are limited by the retaining ring 264 to generate a left axial force, and the elastic positioning seat 16 acts on the first side surface 1422 of the shift shaft 14 to generate a right axial force. At this time, the axial force of the shift shaft 14 is balanced, and the shift head 18 stays in the gear slot of the 3 / 4 gear, and the 3 / 4 gear shift operation can be performed; the shift shaft 14 continues to move to the right, and the positioning ball head of the elastic positioning seat 16 contacts the second step 146 of the shift shaft 14, and the axial force will be significantly increased. Here, the shift head 18 corresponds to the gear slot of the 1 / 2 gear; the shift shaft 14 continues to move to the right, and the positioning ball head passes over the second step 146, and the first spacer 222 contacts the first hole on the inner side of the shell 12 with the retaining ring 262 and is limited. At this time, the shift head 18 stays in the gear slot of the R gear, and the R gear operation can be performed, thereby realizing the double H type shift operation.

[0098] Furthermore, if Figures 3 to 7As shown, the transmission shift device 100 allows the shift shaft 14 to be freely positioned in 3rd / 4th gear or 5th / 6th gear, and can be axially limited in 7th / 8th gear or R gear. The axial force is significantly increased when moving from 1st / 2nd gear to R gear, which plays a certain prompting role, thereby improving the accuracy of gear selection and shifting, and enhancing the user's driving experience. At the same time, during the movement of the shift shaft 14, under the action of the compression force of the elastic positioning seat 16 and the axial force of the spring, the shift shaft 14 is limited and balanced with the housing 12 on the first side 1422 and the second side 1424 of the protruding structure 142, and the gear is divided into two sections. The second side 1424 and its right side can be arranged with 5, 6, 7, and 8 gears, and the first side 1422 and its left side can be arranged with 1, 2, 3, 4, and R gears; when the positioning seat ball head is positioned on the second side 1424, it is ensured that the shift dial head 18 can work in the 5 / 6 gear slot, and when the positioning seat ball head is positioned on the first side 1422, it is ensured that the shift dial head 18 can work in the 3 / 4 gear slot; when the shift shaft 14 moves to the left or right, the spacers at both ends will be limited with the retaining rings in the middle hole, thereby realizing the shifting of other gear slots.

[0099] It can be understood that the transmission shift device 100 of the present invention can be arranged with multiple gears, such as 8 gears, 9 gears, 16 gears (8 gears in a duplicate arrangement), which is conducive to the driver to select and shift gears accurately and clearly, and the gear selection limit is reliable, which effectively improves the shifting quality of the transmission and thus improves the user's driving experience.
