Description

Technical Field

[0001] The utility model relates to the technical field of the fixing of the shift cable, in particular to a pipe clamp bracket. Background Art

[0002] In commercial vehicles, the mechanical transmission is a key transmission component, and the design of its control system directly affects the driving performance of the vehicle and the operation experience of the driver. At present, the shift control of the mechanical transmission of commercial vehicles generally adopts a flexible cable structure. Specifically, one end of the shift cable is connected to the transmission soft shift mechanism on the vehicle chassis, and the other end is connected to the controller inside the vehicle body, enabling the driver to complete the shift operation in the cab.

[0003] In the transmission path from the transmission to the controller, the shift cable needs to be turned over and pass through the front stabilizer bar assembly of the body mount. At present, the shift cable is usually simply tied to the front stabilizer bar of the body mount with a pull strap, or not tied at all and directly leaned against the stabilizer bar. Since the fixing between the flexible cable and the front stabilizer bar of the body mount is not firm, it is easy to deform, squeeze and rub during the operation of the vehicle, resulting in damage to the flexible cable and wear of the stabilizer bar, and further causing jamming during the shift operation, affecting the smoothness and efficiency of the shift control. In addition, due to the random orientation of the flexible cable, the pipeline layout at the front end of the vehicle body is messy, which not only affects the aesthetics of the vehicle, but also may interfere with other components. Once it is necessary to repair or replace the flexible cable, the operation process will become complex and time-consuming. Summary of the Invention

For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0024] The following will describe in detail the embodiments of the present invention in conjunction with the drawings. It should be clear that the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] As Figures 1-3 shown, in some illustrative embodiments, a pipe clamp bracket is provided for supporting and guiding the shift control cable in a vehicle to ensure that it can correctly extend from the transmission end to the body controller, and specifically includes: an upper pipe clamp 10, a lower pipe clamp 20, a rotating shaft 30, and a bracket 40.

[0026] The upper pipe clamp 10 can rotate freely around the rotating shaft 30 to facilitate the opening and closing of the pipe clamp bracket, thereby realizing clamping the pipe clamp bracket on the cylindrical stabilizer bar or removing the pipe clamp bracket from the cylindrical stabilizer bar. The upper pipe clamp 10 specifically includes: an upper semi-circular hoop 11 and an upper rubber gasket 14. The upper semi-circular hoop 11 has a semi-circular cross-section and forms a complete circular ring shape in combination with the lower pipe clamp 20 for clamping the cylindrical stabilizer bar. The semi-circular design enables the pipe clamp to closely fit the surface of the stabilizer bar, providing a good contact area and supporting force.

[0027] One end of the upper semi-circular hoop 11 is provided with a single ear 12, and the other end is provided with an upper flat plate body 13. The single ear 12 is arc-shaped and tangent to and smoothly connected with the upper semi-circular hoop 11. The function of the single ear 12 is to provide a connection point to realize the rotation function of the upper pipe clamp 10 through the rotating shaft 30, that is, when installing or disassembling the pipe clamp bracket, the upper pipe clamp 10 can be rotated to open or close the pipe clamp.

[0028] The lower pipe clamp 20 is used in cooperation with the upper pipe clamp 10 to jointly achieve the clamping function. Among them, the lower pipe clamp 20 includes: a lower semi-circular hoop 21 and a lower rubber gasket 24. The lower semi-circular hoop 21 has a semi-circular cross-section and forms a complete circular ring shape when combined with the upper pipe clamp 10, and the clamping purpose can be achieved when the upper and lower pipe clamps are closed. This fixing method ensures the stability of the pipe clamp bracket on the stabilizer bar.

[0029] One end of the lower semi-circular hoop 21 is provided with double ear rings 22, and the other end is provided with a lower flat plate body 23. The double ear rings 22 are arc-shaped and tangent to and smoothly connected with the lower semi-circular hoop 21, and the double ear rings 22 are connected to the rotating shaft 30. Specifically, the rotating shaft 30 is welded to the two outer end points of the double ear rings 22. The function of the double ear rings 22 is to provide a connection point, and the connection and relative rotation functions of the upper and lower pipe clamps are realized through the rotating shaft 30.

[0030] The single ear ring 12 and the double ear rings 22 are both sleeved on the rotating shaft 30. Empty slots 15 are symmetrically arranged on both sides of the single ear ring 12, and the empty slots 15 are used to accommodate the double ear rings 22. A U-shaped groove 25 for accommodating the single ear ring 12 is opened on the double ear rings 22, so that the single ear ring 12 is located in the middle of the double ear rings 22, and the lower double ear rings 22 are at both ends. The rotating shaft 30 penetrates and connects the upper pipe clamp 10 and the lower pipe clamp 20. This design not only ensures the stability of the pipe clamp bracket, but also improves the flexibility of installation and use. By designing the single ear ring 12 and the double ear rings 22 as an interlocking structure and connecting them through the rotating shaft 30, the reliability of the pipe clamp bracket when bearing a load is ensured.

[0031] The single ear ring 12 and the upper semi-circular hoop 11 form a first S-shaped structural member, and the double ear rings 22 and the lower semi-circular hoop 21 form a second S-shaped structural member. The first S-shaped structural member and the second S-shaped structural member are symmetrical. The single ear ring 12 is arc-shaped and tangent to and smoothly connected with the upper semi-circular hoop 11, forming an S-shaped structure as a whole. The double ear rings 22 are arc-shaped and tangent to and smoothly connected with the lower semi-circular hoop 21, also forming an S-shaped structure as a whole. The design of the above structure increases the stability of the structure, makes the stress distribution more uniform, reduces the stress concentration points, improves the overall strength and durability, and enables the pipe clamp bracket to achieve a compact installation in a limited space, saving space.

[0032] The upper planar plate body 13 is smoothly and transitionally connected to the upper semi-circular hoop 11, and the lower planar plate body 23 is smoothly and transitionally connected to the lower semi-circular hoop 21; through holes 16 are provided on both the upper planar plate body 13 and the lower planar plate body 23. After the through holes 16 on the upper planar plate body 13 and the lower planar plate body 23 are aligned, they are fixed by bolts and nuts to tightly connect the upper and lower pipe clamps together. The design of the through holes 16 enables the pipe clamp bracket to be fixed on the cylindrical stabilizing rod and can be axially adjusted along the stabilizing rod. The smooth and transitional connection between the planar plate body and the semi-circular hoop enhances the stability of the overall structure, avoids stress concentration points, and improves the durability of the structure.

[0033] The upper rubber gasket 14 is disposed on the inner surface of the upper semi-circular hoop 11 and vulcanized into one body with the upper semi-circular hoop 11. The lower rubber gasket 24 is disposed on the inner surface of the lower semi-circular hoop 21 and vulcanized into one body with the lower semi-circular hoop 21. The vulcanization process ensures a firm bond between the rubber gasket and the metal hoop, forming an integral whole, enhancing the stability and durability of the structure. The rubber gasket is used to increase the friction with the stabilizing rod, and the rubber gasket can absorb vibrations and impacts, reducing the vibrations and transmission of the stabilizing rod and the pipe clamp bracket, protecting the surface paint film quality of the stabilizing rod, and extending the service life of the stabilizing rod, the pipe clamp bracket, and other related components.

[0034] The bracket 40 is disposed on the outer side of the upper planar plate body 13. The bracket 40 is in an L shape, and the design of this shape can effectively guide and support the shift soft shaft. The bracket 40 is smoothly and transitionally connected to the upper planar plate body 13. An installation hole 41 for fixing the shift soft shaft is provided on the bracket 40, and the installation hole 41 is used to fix the shift soft shaft. The soft shaft is fixed on the bracket 40 by using a single pipe clamp and bolts and nuts.

[0035] The single ear 12, the double ear 22, and the rotating shaft 30 are on the same axis, achieving coaxial cooperation. This design ensures that the upper and lower pipe clamps can maintain good alignment when rotating, improving the overall stability of the pipe clamp bracket. The shaft diameter of the rotating shaft 30 is the same as the hole diameters of the single ear 12 and the double ear 22, and it is a clearance fit. A clearance fit means that although the diameters are the same, during actual assembly, the hole diameters of the single ear 12 and the double ear 22 are slightly larger than the shaft diameter of the rotating shaft 30 to ensure that the upper pipe clamp 10 can freely rotate around the rotating shaft 30, ensuring the smoothness of the rotation.

[0036] The length of the rotating shaft 30 is the same as the widths of the upper semi-circular hoop 11 and the lower semi-circular hoop 21. The length of the rotating shaft 30 exactly matches the width of the hoop, ensuring that the rotating shaft can penetrate the entire width of the hoop, thereby realizing a stable connection between the upper pipe clamp 10 and the lower pipe clamp 20.

[0037] The upper semi-circular hoop 11, the lower semi-circular hoop 21 and the bracket 40 have the same thickness. This design ensures the structural consistency among the components of the pipe clamp bracket, making the overall structure of the pipe clamp bracket more stable and avoiding problems such as uneven stress or insufficient local strength caused by different thicknesses. The design of the same thickness simplifies the manufacturing process, allows the use of the same materials and processing parameters, and reduces the production cost.

[0038] Installation principle of the pipe clamp bracket:

[0039] Pipe clamp opening: As Figures 1-3 shown, the upper pipe clamp 10 rotates freely around the rotating shaft 30, and the upper pipe clamp 10 and the lower pipe clamp 20 can be opened to facilitate the insertion or removal of the cylindrical stabilizer bar.

[0040] Coaxial fit: The pipe clamp bracket is coaxially fitted with the cylindrical stabilizer bar of the vehicle body suspension, that is, the central axis of the pipe clamp bracket coincides with the central axis of the stabilizer bar.

[0041] Fixing method: The pipe clamp bracket is fixed on the cylindrical stabilizer bar by using bolts and nuts through the first through holes 16 on the upper planar plate body 13 and the lower planar plate body 23. Due to the axial adjustability of the stabilizer bar, the pipe clamp bracket can move axially on the stabilizer bar to adjust to the most suitable installation position. The pipe clamp bracket can also rotate freely around the axial direction of the stabilizer bar to adjust the position as needed.

[0042] Fixing of the shift control shift cable: The shift control shift cable extends from the chassis transmission end to the body controller and passes through the stabilizer bar on the way. The L-shaped bracket 40 is used to guide the cable, and the cable is fixed to the pipe clamp bracket by using a single pipe clamp and bolts and nuts through the second through hole 41.

[0043] Advantages of the pipe clamp bracket:

[0044] Firstly, the pipe clamp bracket can effectively fix the mechanical shift control shift cable on the front stabilizer bar of the body suspension and provide guidance for it, which can avoid extrusion, jamming and wear between the cable and the stabilizer bar, and improve the service life of the cable.

[0045] Secondly, it solves the problems in the prior art such as the random and unfixed routing when the shift control shift cable is connected to the body controller, reduces the mess of the pipelines at the front end of the body, and makes the pipeline layout more orderly.

[0046] Moreover, the ability of the pipe clamp bracket to freely adjust axially along the stabilizer bar and the function of freely rotating 360 degrees around the axial direction of the stabilizer bar make the routing of the shift control cable more smooth and conforming, which helps to improve the efficiency of shift control and makes the driver's operation more smooth and accurate.

[0047] Finally, through the adjustability of the pipe clamp bracket, different installation positions and routing requirements can be accommodated. This design improves the applicable range of the pipe clamp bracket, enabling it to be applicable to a variety of vehicle models and different body layouts.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
