Description

Technical Field

[0001] This utility model relates to the field of automotive shift fork technology, specifically an adjustable adaptive shift fork assembly. Background Technology

[0002] In the field of automotive transmissions, the shift fork, as a key component for achieving gear shifting, directly impacts the driving experience and power transmission efficiency. Currently, traditional automotive shift forks are widely used in various vehicle models, enabling shifting between different gears to a certain extent.

[0003] However, existing automotive shift forks have revealed numerous problems in practical use. Their mechanical structures are often quite complex, containing many interoperating mechanical parts. This not only increases the difficulty of manufacturing and assembly and raises production costs, but also makes the shift forks prone to failure during operation. Due to the large number of mechanical parts, the adjustment process is cumbersome and the precision is difficult to guarantee. For example, when shifting gears, it is necessary to precisely control the displacement and force of the shift fork to ensure accurate gear engagement, but the existing adjustment mechanism of the shift fork cannot meet this high precision requirement, often resulting in shift delays and jerking, which seriously affects the smoothness and comfort of driving.

[0004] Furthermore, traditional shift forks are poorly adaptable to different operating conditions. Vehicle driving conditions are complex and varied, including urban congestion, highway cruising, and mountain climbing, with significant differences in the demand for different gears. Existing shift forks cannot automatically and quickly adjust their state according to actual operating conditions; they can only rely on manual operation by the driver or simple preset logic for gear shifting, making it difficult to fully utilize the engine's performance advantages and achieve optimal fuel economy.

[0005] Therefore, we propose an adjustable adaptive shift fork assembly to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the shortcomings of the prior art, this utility model provides an adjustable adaptive shift fork assembly to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: an adjustable adaptive shift fork assembly, including a main shell plate, on which a sliding groove is provided, a main adjustment cavity is fixedly connected to one side of the main shell plate, and an air pipe is fixedly connected to the main adjustment cavity.

[0010] Preferably, the main shell plate is fixedly connected to an inner adjustment cavity inside the main adjustment cavity away from the main adjustment cavity. A spring is fixedly connected inside the inner adjustment cavity. A push plate is fixedly connected to the end of the spring that is fixed away from the inner adjustment cavity. The push plate is slidably connected inside the inner adjustment cavity.

[0011] Preferably, a transmission rod is fixedly connected to one side of the push plate, and a piston is fixedly connected to the end of the transmission rod away from the push plate. The piston is slidably connected in the main adjustment cavity.

[0012] Preferably, the inner cavity of the main shell plate is fixedly connected to an adjusting component via a motor, the adjusting component has an elongated groove, and a sliding block is slidably connected within the elongated groove.

[0013] Preferably, a connecting rod is vertically fixedly connected to the sliding block, and an N-shaped component is fixedly connected to the upper end of the connecting rod, with the N-shaped component slidably connected in the sliding channel.

[0014] Preferably, a flat connecting strip is fixedly connected to one side of the N-shaped component, and a shift fork is fixedly connected to the end of the flat connecting strip away from the N-shaped component.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an adjustable adaptive shift fork assembly, which has the following advantages:

[0017] 1. This utility model uses the change of the amount of gas inside the assembly to achieve adjustment, which is simpler and faster than the traditional adjustment method. There is no need for complicated mechanical adjustment process. The working state of the shift fork can be quickly changed by a simple gas control device. For example, when the vehicle is in motion and the driving mode needs to be switched due to different road conditions, the amount of gas in the main adjustment chamber can be quickly adjusted so that the shift fork can adapt to the new gear requirements in time, which greatly improves the shifting response speed and brings a smoother driving experience to the driver.

[0018] Meanwhile, it can have precise shift control; the gas regulation has good controllability and can accurately control the displacement and force of the shift fork; during the shifting process, the internal gas volume is precisely adjusted according to the real-time operating conditions of the vehicle and the engine status, thereby precisely controlling the action of the shift fork to drive the gear; this makes the gear meshing more accurate and smooth, effectively avoiding shifting delay and jerking, and significantly improving the smoothness and comfort of driving.

[0019] Furthermore, it possesses excellent adaptive capabilities, automatically adjusting to different driving conditions. In congested urban traffic, frequent starts and stops require rapid gear shifting. In this case, the amount of gas inside the main regulating chamber is reduced, allowing the shift fork to respond quickly to switching between lower gears. During high-speed cruising, the amount of gas is increased, allowing the shift fork to stably maintain a suitable higher gear, ensuring efficient engine operation. This adaptive capability fully leverages the engine's performance advantages, rationally distributing power according to actual needs to achieve optimal fuel economy and reduce vehicle energy consumption and operating costs.

[0020] 2. This utility model, through its overall component design, differs from existing automotive shift fork technology, which typically relies on numerous complex mechanical parts to achieve adjustment and shifting functions. This design abandons the traditional complex mechanical transmission system, primarily achieving shift fork adjustment through changes in the internal gas volume. Its core structure revolves around a gas control unit and a shift fork actuator connected to the gas, significantly reducing the number and types of parts. This offers the following advantages:

[0021] Reduced manufacturing costs; simplification of structural components means fewer raw materials are required during manufacturing, and the production process is also simplified; there is no need to manufacture a large number of high-precision, complex-shaped mechanical parts, thereby reducing mold development costs and processing difficulty;

[0022] Improved assembly efficiency: Fewer parts make the assembly process simpler and clearer; the assembly of traditional shift fork assemblies requires professional technicians to spend a lot of time and effort on precise component positioning and installation and debugging, while the new shift fork assembly only requires assembling a few main components according to a simple process and then connecting the gas control pipeline; this greatly shortens the assembly time, reduces the probability of assembly errors, and improves the efficiency and quality of vehicle production.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0032] Example

[0033] Please refer to Figures 1 to 5 As shown:

[0034] An adjustable adaptive shift fork assembly includes a main housing plate 1 with a sliding groove 2. A main adjustment cavity 3 is fixedly connected to one side of the main housing plate 1, and an air pipe 4 is fixedly connected to the main adjustment cavity 3. An inner adjustment cavity 5 is fixedly connected to the main housing plate 1 away from the main adjustment cavity 3. A spring 6 is fixedly connected to the inner adjustment cavity 5. A push plate 7 is fixedly connected to the end of the spring 6 away from the inner adjustment cavity 5. The push plate 7 is slidably connected within the inner adjustment cavity 5. A transmission rod 8 is fixedly connected to one side of the push plate 7. A piston 9 is fixedly connected to one end of plate 7. The piston 9 is slidably connected in the main adjustment cavity 3. An adjustment component 10 is fixedly connected to the inner cavity of the main shell plate 1 via a motor. An elongated groove 11 is provided on the adjustment component 10. A sliding block 12 is slidably connected in the elongated groove 11. A connecting rod 13 is vertically fixedly connected to the sliding block 12. An N-shaped component 14 is fixedly connected to the upper end of the connecting rod 13. The N-shaped component 14 is slidably connected in the sliding channel 2. A flat connecting strip 15 is fixedly connected to one side of the N-shaped component 14. A shift fork 16 is fixedly connected to the end of the flat connecting strip 15 away from the N-shaped component 14.

[0035] in:

[0036] N-shaped part 14 is slidably adapted to sliding channel 2.

[0037] The air tube 4 is connected to an external air pump, which mainly controls the amount of gas in the main regulating chamber 3 through the air tube 4.

[0038] Spring 6 is mainly used to push plate 7 to reset.

[0039] The elongated groove 11 and the sliding block 12 are slidably adapted.

[0040] The shift fork 16 is used to move the synchronizer or gear, so that it engages or disengages with the gear on the corresponding shaft.

[0041] Working principle:

[0042] When adjusting the shift fork 16, an external air pump is used to pump gas into the main adjustment chamber 3 through the air pipe 4. As the gas is pumped in, the piston 9 in the main adjustment chamber 3 will move away from the air pipe 4 under the action of the gas. During this process, the piston 9 will cause the push plate 7 in the inner adjustment chamber 5 to move through the transmission rod 8. During the movement of the push plate 7, the spring 6 is gradually compressed.

[0043] Furthermore, during the movement of the transmission rod 8, the sliding block 12 fixedly connected to the transmission rod 8 will cause the adjusting member 10 to swing under the action of the elongated groove 11 on the adjusting member 10. During the swing of the adjusting member 10, the connecting rod 13 on the sliding block 12 will slide with the N-shaped member 14 on it under the assistance of the sliding groove 2. As the N-shaped member 14 slides, the flat connecting strip 15 fixedly connected to the N-shaped member 14 will slide with the shift fork 16 on it for a corresponding distance, thereby realizing the shift fork 16 to move the synchronizer or gear.

[0044] Furthermore, this design uses the change of the amount of gas inside the assembly to achieve adjustment, which is simpler and faster than the traditional adjustment method. There is no need for a complicated mechanical adjustment process. The working state of the shift fork 16 can be quickly changed through a simple gas control device. For example, when the vehicle is in motion and the driving mode needs to be switched due to different road conditions, the amount of gas in the main adjustment chamber 3 can be quickly adjusted so that the shift fork 16 can adapt to the new gear requirements in time, which greatly improves the shifting response speed and brings a smoother driving experience to the driver.

[0045] Meanwhile, it can have precise shift control; the gas regulation has good controllability, which can accurately control the displacement and force of the shift fork 16; during the shifting process, the internal gas volume is precisely adjusted according to the real-time operating conditions of the vehicle and the engine status, thereby precisely controlling the action of the shift fork 16 to push the gear; this makes the gear meshing more accurate and smooth, effectively avoiding shift delay and jerking, and significantly improving the smoothness and comfort of driving.

[0046] Furthermore, it possesses excellent adaptive capabilities, automatically adjusting to different driving conditions. In congested urban traffic, frequent starts and stops require rapid gear shifting. In this case, the amount of gas inside the main regulating chamber 3 can be reduced, allowing the shift fork 16 to quickly respond to switching between lower gears. During high-speed cruising, the amount of gas is increased, allowing the shift fork 16 to stably maintain a suitable high gear, ensuring efficient engine operation. This adaptive capability can fully utilize the engine's performance advantages, rationally distribute power according to actual needs, achieve optimal fuel economy, and reduce vehicle energy consumption and operating costs.

[0047] Furthermore, through the overall component design, this design differs from existing automotive shift fork 16 technology, which typically relies on numerous complex mechanical parts to achieve adjustment and shifting functions. It abandons the traditional complex mechanical transmission system, primarily achieving shift fork 16 adjustment through changes in internal gas volume. Its core structure revolves around the gas control unit and the shift fork 16 actuator connected to the gas, significantly reducing the number and types of parts. This offers the following advantages:

[0048] Reduced manufacturing costs; simplification of structural components means fewer raw materials are required during manufacturing, and the production process is also simplified; there is no need to manufacture a large number of high-precision, complex-shaped mechanical parts, thereby reducing mold development costs and processing difficulty;

[0049] Improved assembly efficiency: Fewer parts make the assembly process simpler and clearer; the assembly of the traditional shift fork 16 assembly requires professional technicians to spend a lot of time and effort on precise component positioning and installation and debugging, while the new shift fork 16 assembly only requires assembling a few main components according to a simple process and then connecting the gas control pipeline; this greatly shortens the assembly time, reduces the probability of assembly errors, and improves the efficiency and quality of vehicle production.
