[0036] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0037] The speed shift operating mechanism 1 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0038] like Figure 1-Figure 5 As shown, the speed shift operating mechanism 1 according to the embodiment of the utility model includes a manipulator 100 and a flexible shaft mechanism 200 .

[0039] The manipulator 100 is mounted on the powertrain 20 and is suitable for passing through the cab floor 10. The flexible shaft mechanism 200 includes a gear selection flexible shaft 210 and a gear shift flexible shaft 220, one end of the gear selection flexible shaft 210 and the gear shift flexible shaft 220 are connected to the manipulator 100, the gear selection flexible shaft 210 and the gear shift flexible shaft 220 extend to the rear of the manipulator 100, and the other end of the gear selection flexible shaft 210 and the gear shift flexible shaft 220 are connected to the powertrain 20.

[0040] For example, during the assembly process, the speed shift control mechanism 1 can be first passed through the cab floor 10 and assembled to the cab floor 10 by bolts, and then the flexible shaft pipe clamps are respectively clamped to the color codes of the gear selection flexible shaft 210 and the gear shift flexible shaft 220, and the gear selection flexible shaft 210 and the gear shift flexible shaft 220 are respectively fixed to the powertrain 20 by bolts.

[0041] According to the speed control mechanism 1 of the embodiment of the utility model, the manipulator 100 passes through the cab floor 10. When the cab is flipped, only the cab floor 10 flips, and the manipulator 100 and the powertrain 20 remain fixed. At the same time, the gear selection flexible shaft 210 and the shift flexible shaft 220 extend to the rear of the manipulator 100. Compared with the speed control mechanism in the related art in which the flexible shaft mechanism passes through the gap between the intercooler and the body accessories for many times, the speed control mechanism 1 of this embodiment can make better use of the space at the rear of the vehicle body, reduce the complicated arrangement of pipe harnesses and the interference with important components at the bottom of the vehicle, further optimize the space layout, and improve space utilization.

[0042] In addition, the gear selection flexible shaft 210 and the gear shift flexible shaft 220 extend from the manipulator 100 to the rear of the powertrain 20. The connection method makes the direction of the flexible shaft mechanism 200 smoother, reduces the bending angle and bending radius, helps to reduce the stress concentration generated by the flexible shaft mechanism 200 during the bending process, and improves the reliability and stability of the flexible shaft mechanism 200.

[0043] Therefore, the speed shift operating mechanism 1 according to the embodiment of the utility model has the advantages of improving space utilization and the bending radius of the flexible shaft mechanism.

[0044] In some specific embodiments of the present invention, Figure 1 and Figure 4 As shown, the speed control mechanism 1 also includes a first flexible shaft bracket 300. The first flexible shaft bracket 300 is suitable for being installed on the longitudinal beam 30, and the gear selection flexible shaft 210 and the gear shift flexible shaft 220 are both installed on the first flexible shaft bracket 300. The first flexible shaft bracket 300 is installed on the longitudinal beam 30 of the vehicle, providing a stable support point for the gear selection flexible shaft 210 and the gear shift flexible shaft 220, ensuring that the flexible shaft mechanism 200 maintains the correct installation position during the operation of the vehicle, avoiding the misalignment or damage of the flexible shaft mechanism 200 due to vibration or movement, and ensuring the accuracy and reliability of the speed control mechanism 1. At the same time, by integrating the flexible shaft mechanism 200 on the first flexible shaft bracket 300, the wiring and pipeline layout of the vehicle bottom can be optimized, avoiding interference between the flexible shaft mechanism 200 and other components, especially in the interior of the vehicle with limited space, making rational use of space, making maintenance and inspection more convenient.

[0045] In some specific embodiments of the present invention, Figure 4As shown, the first flexible shaft bracket 300 includes a mounting arm 310 and a mounting block 320. The mounting arm 310 is suitable for mounting on the longitudinal beam 30. The gear shift flexible shaft 210 and the gear selection flexible shaft 220 are passed through the mounting block 320 and fixed by the mounting block 320. A mounting hole is configured in the middle of the mounting block 320, and the flexible shaft 210 and the gear selection flexible shaft 220 are respectively passed through the mounting holes and fixed to the first flexible shaft bracket 300, and the fasteners are sequentially passed through the top of the mounting block 320 and the mounting arm 310 to be fixedly connected with the longitudinal beam 30.

[0046] In general, the mounting arm 310 is installed on the longitudinal beam 30, and the mounting arm 310 provides a stable support platform, which can effectively fix the position of the first flexible shaft bracket 300, ensure that the flexible shaft mechanism 200 does not shake or loosen during operation, and maintain its stability and reliability. The mounting block 320 is a component through which the shift flexible shaft 210 and the gear selection flexible shaft 220 pass and are fixed. The position of the flexible shaft mechanism 200 is fixed by the mounting block 320, ensuring that the flexible shaft mechanism 200 does not move or deviate during the transmission process, ensuring the normal working state of the flexible shaft mechanism 200, and avoiding transmission failure or damage.

[0047] In some specific embodiments of the present invention, Figure 4 As shown, the mounting arm 310 includes a vertical plate portion 311 and a horizontal plate portion 312. The vertical plate portion 311 is suitable for being mounted on the outer side of the longitudinal beam 30. The horizontal plate portion 312 is connected to the top of the vertical plate portion 311 and extends to the inner side of the longitudinal beam 30, and the mounting block 320 is mounted on the horizontal plate portion 312. The vertical plate portion 311 can be in an "L" shape, providing a vertical mounting surface, which can increase the contact area with the longitudinal beam 30, and can ensure that the mounting arm 310 is firmly connected to the longitudinal beam 30 and provide the necessary supporting force. By combining the vertical plate portion 311 with the longitudinal beam 30, the structural stability of the entire mounting arm 310 is enhanced, ensuring that the mounting arm 310 will not easily be displaced or deformed under the vibration and impact during the vehicle driving process, thereby ensuring the stability and reliability of the speed control mechanism 1. The horizontal plate portion 312 extends from the top of the vertical plate portion 311 to the inner side of the longitudinal beam 30, providing a horizontal mounting platform for the mounting block 320. Such a structure can keep the mounting block 320 away from the vibration source of the vehicle, reduce the direct vibration impact on the speed shift operating mechanism 1, and improve the smoothness of operation.

[0048] In some specific embodiments of the present invention, Figure 4 As shown, the mounting block 320 includes a lower mounting block 321 and an upper mounting block 322. The lower mounting block 321 is mounted on the mounting arm 310. The upper mounting block 322 is fixed to the lower mounting block 321 by passing fasteners, and the gear shift flexible shaft 220 and the gear selection flexible shaft 210 are clamped by the upper mounting block 322 and the lower mounting block 321.

[0049] By matching the upper mounting block 322 and the lower mounting block 321, the shift flexible shaft 220 and the gear selection flexible shaft 210 can be firmly clamped, ensuring that the flexible shaft mechanism 200 can remain stable under any driving conditions, avoiding displacement due to vibration or external force, and ensuring the accuracy and reliability of the speed control mechanism 1.

[0050] In some specific embodiments of the present invention, Figure 5 As shown, the speed control mechanism 1 further includes a second flexible shaft bracket 400. The second flexible shaft bracket 400 is mounted on the power assembly 20, and the second flexible shaft bracket 400 includes an upper wing plate 410 and a side wing plate 420. The gear selection flexible shaft 210 is mounted on the upper wing plate 410 through a pipe clamp, and the gear shift flexible shaft 220 is mounted on the side wing plate 420 through a pipe clamp. The second flexible shaft bracket 400 is connected to the power assembly 20 by a fastener on one side of the upper wing plate 410 and the side wing plate 420. The second flexible shaft bracket 400 is used as a mounting bracket of the flexible shaft mechanism 200. By being mounted on the power assembly 20, the second flexible shaft bracket 400 provides fixed support for the gear shift flexible shaft 220 and the gear selection flexible shaft 210. The second flexible shaft bracket 400 is respectively mounted on the upper wing plate 410 and the side wing plate 420 through a pipe clamp, ensuring that the flexible shaft mechanism 200 maintains a stable position during operation, reducing the shaking and friction of the flexible shaft mechanism 200 during the transmission process, and improving the working efficiency and reliability of the speed control mechanism 1.

[0051] In some specific embodiments of the present invention, Figure 1 and Figure 3 As shown, the gear shift flexible shaft 220 and the gear selection flexible shaft 210 are both bent and extended toward the rear and downward of the manipulator 100, and the bending radius of the gear shift flexible shaft 220 and the gear selection flexible shaft 210 is not less than 250 mm.

[0052] The shift flexible shaft 220 and the gear selection flexible shaft 210 bend and extend backward and downward, making full use of the longitudinal and vertical space of the vehicle, avoiding the complex pipes and lines that may be encountered when the shift flexible shaft 220 and the gear selection flexible shaft 210 directly pass through the bottom of the cab floor 10, which helps to optimize the spatial layout of the cab and leave more space for other systems and components. Setting the bending radius to be not less than 250mm can effectively reduce the stress concentration of the flexible shaft mechanism 200 at the bend and avoid material fatigue and wear caused by excessive bending. A larger bending radius helps to extend the service life of the flexible shaft mechanism 200, reduce the frequency of maintenance and replacement, and improve the overall operating efficiency of the vehicle.

[0053] In some specific embodiments of the present invention, Figure 1As shown, the power assembly 20 includes an engine 21 and a gearbox 22. The gearbox 22 is installed at the rear side of the engine 21, and is configured with a gear selection rocker arm 201 and a gear shift rocker arm 202. The gear shift rocker arm 202 is rotatable in the transverse direction, and the gear selection rocker arm 201 is rotatable in the longitudinal direction. The gear selection flexible shaft 210 is connected to the gear selection rocker arm 201, and the gear shift flexible shaft 220 is connected to the gear shift rocker arm 202.

[0054] By connecting the gear selection rocker arm 201 and the gear shift rocker arm 202 to the gear selection flexible shaft 210 and the gear shift flexible shaft 220, the gear shift rocker arm 201 and the gear selection rocker arm 202 are driven to rotate, so as to realize the gear shifting and gear selection of the gears in the gearbox 22, thereby controlling the transmission ratio of the vehicle, so that the output torque and speed of the engine 21 can adapt to different driving speeds and load conditions. And by setting the gear shift rocker arm 201 and the gear selection rocker arm 202 to rotate in the horizontal direction and the longitudinal direction respectively, the independent control of the gear shifting and gear selection is realized. This structure allows the driver to perform the gear shifting and gear selection operations more accurately, improves the accuracy and response speed of the speed change operation, and thus improves the driving experience and the handling performance of the vehicle.

[0055] In some specific embodiments of the present invention, Figure 1 As shown, the engine 21 is configured with a gear bracket 203, and the manipulator 100 includes a manipulation handle 110 and a base 120. The manipulation handle 110 is suitable for passing through the cab floor 10. The base 120 is installed on the gear bracket 203, and the base 120 is configured with a flexible shaft channel extending backward, and the gear selection flexible shaft 210 and the gear shifting flexible shaft 220 are penetrated in the flexible shaft channel.

[0056] The base 120 is installed on the gear bracket 203, and the operating handle 110 passes through the cab floor 10, so that the manipulator 100 is fixed, which can ensure that the manipulator 100 will not shake or shift during driving, thereby improving the stability and reliability of the operation. At the same time, the structure of the flexible shaft channel extending to the rear optimizes the layout of the gear selection flexible shaft 210 and the gear shift flexible shaft 220, fully utilizes the longitudinal space of the vehicle, avoids the interference between the gear selection flexible shaft 210 and the gear shift flexible shaft 220 and other components in the cab, saves precious space in the vehicle, and helps to improve the spaciousness and comfort of the cab.
