[0032] A shift actuator 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] like Figure 1-Figure 5 As shown, the shift actuator 1 according to the embodiment of the present utility model includes a shift rocker arm 100 , an actuator base 200 , a hollow bolt 300 and a nut 400 .

[0034] The shift rocker arm 100. The shift rocker arm 100 is mounted on the manipulator base 200. A through hole 310 is formed at the radial center of the hollow bolt 300, and an external thread 320 is configured on the outer peripheral surface of the hollow bolt 300. The hollow bolt 300 is penetrated through the manipulator base 200. The inner peripheral surface of the nut 400 is configured with an internal thread 410 to be connected with the external thread 320 of the hollow bolt 300. Among them, the through hole 310 is suitable for penetrating a fastener (not shown in the figure) to enable the manipulator base 200 to be installed on the cab floor (not shown in the figure).

[0035] For example, the hollow bolt 300 is a steel sleeve bolt, the nut 400 is a steel sleeve nut, and the thread performance level of the external thread 320 and the internal thread 410 of the hollow bolt 300 and the nut 400 reaches 10.9. During the vehicle assembly process, the shift actuator 1 is connected to the interior of the cab by fasteners. Among them, the hollow bolt 300 passes through the actuator base 200, the external thread 320 of the hollow bolt 300 and the internal thread 410 of the nut 400 are threadedly connected to form an integrated structure, and a through hole 310 is formed at the center of the hollow bolt 300, and the fastener passes through the through hole 310 to connect the actuator base 200 with the cab floor.

[0036] According to the shift actuator 1 of the embodiment of the utility model, through the threaded integrated structure connection between the hollow bolt 300 and the nut 400, the shift actuator 1 can be simply and conveniently installed on the cab floor by inserting fasteners, and the hollow bolt 300 and the nut 400 will not fall out during the assembly process, thereby saving assembly time and improving assembly efficiency. At the same time, the connection between the outer thread 320 and the inner thread 410 of the hollow bolt 300 and the nut 400 has a more firm and stable fixing effect. Through the tight connection between the outer thread 320 and the inner thread 410, the connection strength of the hollow bolt 300 and the nut 400 can be effectively improved, and the hollow bolt 300 and the nut 400 will not fall off, and it is ensured that the actuator base 200 does not loosen or shift, providing sufficient support force for the inserted fasteners, and improving the reliability of the shift actuator 1 during use. Moreover, the hollow bolt 300 and the nut 400 can maintain structural stability under long-term use and various environmental conditions. The hollow bolt 300 and the nut 400 are both hard parts, and are less susceptible to wear than rubber parts in related technologies, thereby increasing the reliability between the hollow bolt 300 and the nut 400 and increasing their service life.

[0037] Therefore, the shift actuator 1 according to the embodiment of the utility model has the advantages of improved assembly efficiency, low risk of falling off, and long service life.

[0038] In addition, the inner circumference of the through hole 310 of the hollow bolt 300 can also adopt an internal thread structure to cooperate with threaded fasteners to be installed with the cab floor, so that the connection between the hollow bolt 300 and the fastener at the center is more firmly established.

[0039] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the hollow bolt 300 includes a nut 301 and a screw rod 302. The nut 301 abuts against one side surface of the manipulator base 200. The screw rod 302 is connected to the nut 301 and penetrates to the other side surface of the manipulator base 200. The outer contours of the nut 301 and the nut 400 are both configured as regular polygons.

[0040] For example, the middle portion of the bolt 302 is a cylindrical hollow structure, which can reduce the amount of material used and thus reduce the overall weight of the shift actuator 1. At the same time, fasteners can be inserted through the hollow structure to fix the gearbox and the vehicle chassis, and transmit the force and vibration of the actuator base 1 to the vehicle chassis. The outer contours of the nut 301 and the nut 400 are both constructed as regular polygons, which can be regular hexagons, which are convenient for tightening with operating tools such as wrenches, making the hollow bolt 300 and the nut 400 easier to adjust and rotate, convenient for operation and installation, and saving installation time. The hollow bolt 300 and the nut 400 are easier to tighten, thereby increasing the connection strength between the hollow bolt 300 and the nut 400, thereby improving the stability of the connection of the shift actuator 1, such as Figure 2 As shown, the nut 301 abuts against the bottom surface of the manipulator base 200, and the nut 400 abuts against the top surface of the manipulator base 200. The nut 301 and the nut 400 abut against the bottom surface and the top surface of the manipulator base 200, respectively, can limit and control the movement of the manipulator base 1 in the vertical direction, ensure that the hollow bolt 300 and the nut 400 are in firm contact with the manipulator base 200, ensure that the shift manipulator 1 is kept in a predetermined position, and prevent it from loosening or falling off during use.

[0041] In some specific embodiments of the present invention, Figure 2 As shown, the end face of the nut 400 is flush with the end face of the hollow bolt 300. The structure of keeping the two end faces flush can ensure the alignment of the nut 400 and the hollow bolt 300, avoid the offset and misalignment of the nut 400 and the hollow bolt 300, and ensure the smoothness and stability of the shifting operation. At the same time, the end face of the nut 400 and the end face of the hollow bolt 300 are kept flush, which can ensure that the tightening force between the nut 400 and the hollow bolt 300 is uniform, improve the tightening force, and avoid the loosening of the hollow bolt 300.

[0042] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, a spacer 330 is formed between the external thread 320 of the hollow bolt 300 and the nut 301 along the axial direction. Since no thread mechanism is provided in the spacer 330, there is a distance between the external thread 320 and the nut 301, and the hollow bolt 300 will not be over-tightened during the connection between the nut 400 and the hollow bolt 300, thus avoiding stress concentration and improving the service life of the shift actuator 1.

[0043] In some specific embodiments of the present invention, Figure 2As shown, the outer contour of the nut 301 of the hollow bolt 300 is the same as the outer contour of the nut 400 in shape and size, for example, both are external hexagonal structures. The nut 301 and the nut 400 with the same contour can be installed and removed more easily, and the operator can use the same tool to tighten the nut 301 and the nut 400 without switching different types of tools, which improves the convenience and simplicity of operation and saves operation time. By using the nut 301 and the nut 400 with the same contour, a more unified design and manufacturing process can be achieved, and the components such as the nut 301 and the nut 400 can be produced through standardized production lines and processes, thereby improving production efficiency.

[0044] In some specific embodiments of the present invention, Figure 4 As shown in d, the dimension of the external thread 320 of the hollow bolt 300 along the axial direction of the hollow bolt 300 is not less than 6 mm and is greater than the thickness of the nut 400. By limiting the dimension of the external thread 320, the connection between the hollow bolt 300 and the nut 400 can be ensured to be stable and reliable, and will not loosen or fall off due to too small a dimension. The shift actuator 1 needs to withstand large vibration and impact during use. If the dimension of the external thread 320 is too small, it may affect the connection and affect the working effect of the shift actuator 1.

[0045] At the same time, the width of the external thread 320 is greater than the width of the nut 400, which can provide sufficient contact area to ensure that the nut 400 is fully movable within the range of the external thread 320, thereby increasing the stability and reliability of the connection between the hollow bolt 300 and the nut 400.

[0046] In some specific embodiments of the present invention, Figure 1 As shown, the hollow bolts 300 and nuts 400 are arranged in pairs, and the pairs of hollow bolts 300 and nuts 400 are arranged at intervals on both sides of the manipulator base 200. The hollow bolts 300 and nuts 400 arranged in pairs can increase the stability and balance of the shift manipulator 1. By arranging the hollow bolts 300 and nuts 400 on both sides of the manipulator base 200, the balance state of the shift manipulator 1 during use can be ensured to avoid tilting or instability. And by rotating the nut 400, the hollow bolts 300 and the nuts 400 can be easily connected or separated, thereby achieving rapid installation and disassembly, and convenient maintenance and replacement.

[0047] In some specific embodiments of the present invention, the hollow bolt 300 and the nut 400 are both alloy steel parts. The alloy steel parts have high strength and hardness, can withstand greater force and pressure, and improve the strength and durability of the shift actuator 1. At the same time, the alloy steel parts have good corrosion resistance and are not easy to rust or corrode when working in a humid, dusty and harsh environment. In addition, the hollow bolt 300 and the nut 400 constructed of alloy steel parts can reduce the overall weight of the shift actuator 1 structure under the condition of providing sufficient strength, which helps to improve the economic efficiency of the shift actuator 1.
