[0037] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0038] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0039] See also Figures 1 to 3 The embodiment of the present application provides a connection tool for a steering gear input shaft, which includes: a tool body 100, a clamping member 200 and an adjusting member 300.

[0040] The tool body 100 has a first end and a second end which are arranged opposite to each other along its own axial direction Z. A connecting slot 101 is arranged on the first end of the tool body 100, and the connecting slot 101 extends from the first end to the second end;

[0041] The clamping member 200 is movably disposed in the connecting slot 101; and

[0042] The adjusting member 300 is movably disposed on the first end of the tool body 100 and abuts against the outer peripheral side of the clamping member 200 to adjust the radial X dimension of the clamping member 200 .

[0043] In this embodiment, the radial X dimension of the first end of the connecting tool used to connect the steering gear input shaft is set to an adjustable mode, so that the connecting tool can be adapted to the steering gear input shafts of different sizes by directly adjusting the embracing dimension of the first end, thereby shortening the assembly time of the connecting tool, shortening the test time, and improving the test efficiency. When the radial X dimension of the steering gear input shaft is different, the position of the adjusting member 300 extending into the connecting slot 101 is directly adjusted to push the clamping member 200 to a predetermined radial X dimension, thereby adjusting the radial X dimension for clamping the input shaft, avoiding the complicated operation of first disassembling the connecting tool of an inappropriate size and then replacing the connecting tool of an appropriate size in the traditional operation, reducing the test assembly time, reducing the labor intensity of the test operator, and improving the test efficiency.

[0044] Specifically, the connecting tool is configured as a combined component including at least a tool body 100, a clamping member 200 and an adjusting member 300. The tool body 100 may be a long rod structure. The first end of the tool body 100 is used to connect the input shaft of the steering gear, and the second end of the tool body 100 is used to connect the torque plate of the test equipment. A connecting slot 101 is provided on the first end. The connecting slot 101 may be a cylindrical slot structure to match the shape of the input shaft of the steering gear. The clamping member 200 may be an arc-shaped clip. The clamping member 200 is movably arranged in the connecting slot 101 and can reciprocate along the radial direction X of the tool body 100 to enclose with the corresponding clamping member 200 or the inner wall of the connecting slot 101 to form a clamping space, and the input shaft of the steering gear is inserted in the clamping space. The adjusting member 300 can be an adjusting rod, which is movably inserted into the connecting slot 101 at the first end. The inner end of the adjusting member 300 abuts against the outer wall of the clamping member 200. In this way, the clamping member 200 can maintain a fixed radial X position, so that the clamping space is stable, the clamping member 200 has strong clamping stability for the input shaft, and the connection between the tooling body 100 and the steering gear input shaft is strong.

[0045] The use process of the connection tool is as follows: insert the input shaft into the clamping space, adjust the position of the adjusting member 300 so that it continues to extend into the connection slot 101 and presses against the clamping member 200, and the clamping member 200 holds the input shaft tightly to complete the connection on the steering gear side. When the input shaft size of the next steering gear is small, directly insert the input shaft of the next steering gear into the clamping space, continue to adjust the adjusting member 300 in the same direction so that it continues to extend into the connection slot 101 and presses against the clamping member 200, and the clamping member 200 holds the input shaft tightly to complete the connection of the steering gear with a smaller input shaft size. When the input shaft size of the next steering gear is large, first adjust the adjusting member 300 in the reverse direction so that the adjusting member 300 extends out of the connection slot 101, and then insert the input shaft of the next steering gear into the clamping space, adjust the adjusting member 300 so that the adjusting member 300 extends into the connection slot 101 and presses against the clamping member 200, and the clamping member 200 holds the input shaft tightly to complete the connection of the steering gear with a larger input shaft size.

[0046] In a possible implementation, a movable groove 102 extending along the radial direction X of the tool body 100 is provided at the bottom of the connection slot 101, and the clamping member 200 is movably connected to the connection slot 101 through the movable groove 102. Such a configuration can simplify the internal structure of the connection tool, reduce the cost of the connection tool, make the entire connection tool layout compact, and facilitate the realization of a miniaturized layout.

[0047] like Figure 2 As shown, the movable groove 102 may be a strip-shaped groove body extending along the radial direction X of the tool body 100, which is arranged at the bottom of the connecting slot 101 to form an active area at the bottom. One end of the clamping member 200 is inserted into the movable groove 102, and the other end extends toward the opening of the connecting slot 101 along the axial direction Z of the tool body 100, so as to form a clamping length area for clamping the input shaft in the axial direction Z of the tool body 100, thereby increasing the clamping length of the clamping member 200 on the input shaft and improving the clamping stability of the clamping member 200 on the input shaft.

[0048] Of course, in other embodiments, the clamping member 200 can also be flexibly connected through a pulley-slide rail structure. The connecting end of the clamping member 200 is provided with a pulley structure, and the bottom of the connecting slot 101 is provided with a slide rail structure, which can extend along the radial direction X of the tooling body 100.

[0049] In a possible implementation, the clamping member 200 includes a T-shaped connecting portion 210 and an arc-shaped clamping portion 220 connected to each other, the T-shaped connecting portion 210 is movably arranged in the movable groove 102, the inner side of the arc-shaped clamping portion 220 is used to clamp the input shaft of the steering gear, and the adjusting member 300 abuts against the outer side of the arc-shaped clamping portion 220. In this arrangement, while realizing the movable connection of the clamping member 200, the stable clamping of the input shaft by the clamping member 200 can be improved, and the connection tightness between the connecting tool and the steering gear can be improved.

[0050] like Figure 3 As shown, in the axial direction Z of the tooling body 100, the cross-sectional shape of the movable groove 102 is T-shaped to match the T-shaped connecting portion 210 of the clamping piece 200. In this way, the T-shaped connecting portion 210 can be movably connected in the movable groove 102 to achieve free movement along the radial direction X of the tooling body 100; and can be firmly inserted in the movable groove 102 without falling off from the movable groove 102 under the T-zone limit of the T-shaped movable groove 102, thereby improving the connection tightness between the clamping piece 200 and the tooling body 100. The adjusting member 300 abuts against the outer wall of the arc-shaped clamping portion 220 of the clamping member 200, so that the adjusting member 300 can limit the clamping member 200 from moving toward the inner wall of the connecting slot 101, so that the clamping member 200 is kept at a fixed radial X position; and the inner side of the clamping member 200 is used to clamp the input shaft, so that the adjusting member 300 and the clamping member 200 can provide a stable clamping space for insertion for the input shaft, reduce the connection gap between the clamping member 200 and the input shaft, enable the clamping member 200 to clamp the input shaft, and improve the connection tightness between the connecting tooling and the steering gear.

[0051] In one example, the T-shaped connecting portion 210 and the arc-shaped clamping portion 220 of the clamping member 200 are sequentially arranged along the axial direction Z of the tooling body 100 . The horizontal T area of ​​the T-shaped connecting portion 210 is spaced apart from the arc-shaped clamping portion 220 , and the vertical connecting area of ​​the T-shaped connecting portion 210 is connected to the arc-shaped clamping portion 220 .

[0052] In a possible implementation, a buffer member (not shown) is further included, and the buffer member is arranged inside the arc-shaped clamping portion 220. Such an arrangement can prevent the clamping member 200 from damaging the input shaft when clamping the input shaft. At the same time, the buffer member can also increase the friction between the clamping member 200 and the input shaft, and enhance the connection reliability between the clamping member 200 and the input shaft. For example, but not limited to, the buffer member can be a rubber pad, and its shape is the same as that of the arc-shaped clamping portion 220.

[0053] In a possible embodiment, an adjustment hole extending along the radial direction X of the tooling body 100 is provided on the first end of the tooling body 100, the adjustment hole is connected to the connecting slot 101, an internal thread is provided in the adjustment hole, an external thread is provided on the adjusting member 300, and the adjusting member 300 is adjustably connected to the adjustment hole through the external thread and the internal thread.

[0054] In this embodiment, the connection mode between the adjusting member 300 and the tool body 100 is optimized. Specifically, an adjusting hole with an internal thread is arranged on the first end of the tool body 100, and an external thread matching the internal thread is arranged on the adjusting member 300, so that the adjusting member 300 can be rotatably connected to the first end of the tool body 100 through the threaded connection between the external thread and the internal thread. The adjusting hole can be a cylindrical long hole, which is transversely arranged at the first end of the tool body 100 and connects the external environment and the connection slot 101; the adjusting member 300 can be a long screw, which is inserted into the connection slot 101 through one end of the adjusting hole, and the other end extends out of the outer wall of the tool body 100. In this way, the end of the adjusting member 300 that is exposed by rotating the tool body 100 can be adjusted to adjust the depth of the adjusting member 300 extending into the connecting slot 101, thereby adjusting the radial X position of the clamping member 200 and adjusting the clamping size of the clamping member 200, so that the connecting tool can meet the connection requirements of steering gears with different input shaft sizes, thereby improving the application range and flexibility of the connecting tool.

[0055] In a possible implementation, a plurality of clamping members 200 are provided, and the plurality of clamping members 200 are spaced apart and distributed on the inner circumference of the connecting slot 101 . A plurality of adjusting members 300 are provided, and at least one adjusting member 300 is provided corresponding to a clamping member 200 .

[0056] like Figure 1 and Figure 2 As shown, in order to improve the clamping accuracy of the input shaft, a plurality of clamping members 200 and a plurality of adjusting members 300 are provided, so as to improve the adjustment accuracy and clamping stability of the connecting tooling to the input shaft through the configuration between the plurality of components.

[0057] For example but not limited to, four clamping members 200 and four adjusting members 300 are provided. At this time, a movable groove 102 with a cross-shaped structure is provided at the bottom of the connecting slot 101, and the four clamping members 200 are respectively inserted into the four branch grooves of the movable groove 102; four adjusting holes are provided, and the four adjusting holes are respectively arranged below each end of the movable groove 102, and an adjusting member 300 is movably inserted into one of the adjusting holes. At this time, the four clamping members 200 and the adjusting members 300 are respectively located in four directions of the first end of the tooling body 100. By adjusting the insertion depth of the adjusting member 300 in one direction, the radial X position of the clamping member 200 in this direction can be adjusted, and the clamping member 200 in this direction can be tightly fitted on the outer wall of the input shaft, thereby improving the connection tightness between the clamping member 200 in this direction and the input shaft. The adjustment mechanisms in other directions are the same as above, and will not be repeated here. In this way, by adjusting the clamping member 200 in different directions, precise adjustment of the connection between the connecting tool and the input shaft can be achieved, thereby improving the stability of the connection between the connecting tool and the input shaft.

[0058] In a possible embodiment, the tooling body 100 includes a first connecting member 110 and a second connecting member 120 connected to each other, the radial X dimension of the first connecting member 110 is greater than the radial X dimension of the second connecting member 120, the first connecting member 110 is used to connect the input shaft of the steering gear, and the second connecting member 120 is used to connect the torque disk of the test equipment.

[0059] In this embodiment, the specific configuration of the tooling body 100 is optimized. Specifically, the tooling body 100 is configured as a composite component including at least a first connector 110 and a second connector 120, wherein the first connector 110 can be a short connecting rod, and the second connector 120 can be a long connecting rod, and the second connector 120 is coaxially connected to the first connector 110. The radial X dimension of the first connector 110 is larger than the radial X dimension of the second connector 120, so as to reserve a sufficiently wide moving space for the clamping member 200, realize the clamping of input shafts of more sizes, and improve the adaptability range of the connecting tooling. In addition, the axial Z dimension of the first connector 110 is smaller than the axial Z dimension of the second connector 120, so as to reduce the space occupied by the first connector 110 and realize the miniaturization and sophisticated layout of the connecting tooling.

[0060] In a possible embodiment, the second connecting member 120 is provided with adjacent spline segments 121 and limit segments 122, wherein the spline segment 121 is located on the side of the limit segment 122 away from the first connecting member 110, and is used to connect with the mounting hole on the torque plate, and the limit segment 122 is used to limit the torque plate from continuing to move toward the first connecting member 110.

[0061] In this embodiment, the specific configuration of the second connecting member 120 is optimized. Specifically, the second connecting member 120 is configured as a combined component including at least a spline segment 121 and a limiting segment 122. The outer wall of the spline segment 121 is provided with a spline that matches the mounting hole of the torque disc, so as to prevent the torque disc from rotating in the circumferential direction of the tooling body 100, thereby improving the connection stability between the spline segment 121 and the torque disc; the outer wall of the limiting segment 122 is an arc-shaped conical surface with a certain slope, and the large-size end of the arc-shaped conical surface faces the first connecting member 110, so as to prevent the torque disc from continuing to move in the direction close to the first connecting member 110, thereby improving the axial Z position stability of the torque disc and ensuring a safe distance between the torque disc and the steering gear.

[0062] In one example, the second connecting member 120 is further provided with a connecting section 123, which can be a cylindrical structure with a smooth outer wall, and is arranged between the limiting section 122 and the first connecting member 110 to ensure a safe distance between the torque plate and the steering input shaft.

[0063] In one example, the axial Z length of the connecting segment 123 is greater than the axial Z length of the limiting segment 122 , and the axial Z length of the limiting segment 122 is not much different from the axial Z length of the spline segment 121 .

[0064] In a possible embodiment, a threaded section 124 is further provided on the second connecting member 120, and the threaded section 124 is arranged on the side of the spline section 121 away from the limiting section 122. The connecting tool also includes a locking piece (not shown in the figure), which is connected to the threaded section 124 to lock the torque plate and the second connecting member 120.

[0065] In this embodiment, the specific configuration of the first connecting member 110 is further optimized. Specifically, the second connecting member 120 is configured as a composite member including at least a spline section 121, a limit section 122 and a threaded section 124, and an external thread is provided on the outer wall of the threaded section 124. At the same time, a locking member that cooperates with the threaded section 124 is provided, and the locking member can be a nut, on which an internal thread that matches the external thread is provided. In this way, the connection and tightening of the locking member and the threaded section 124 can be achieved through the threaded connection between the external thread and the internal thread, preventing the torque disk from moving along the axial direction Z of the tooling body 100, improving the connection stability of the torque disk, and ensuring the stability of the working environment of the torque disk.

[0066] In the second aspect, the present application also provides a steering test bench, including the connection fixture as described above. The specific structure of the connection fixture refers to the above embodiment. Since the present steering test bench adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0067] In this embodiment, the connecting tool as described above is configured on the steering test bench. When facing input shafts of different sizes, the radial X position of the clamping member 200 of the connecting tool can be directly adjusted by the adjusting member 300, so as to adjust the clamping size of the clamped input shaft, thereby avoiding the problems of long test time and low detection efficiency caused by re-changing the connecting tool, and improving the detection efficiency of the steering test bench.
