Technical Field

[0001] The utility model relates to a reverse sliding shaft caliper assembly. Background Art

[0002] At present, with the development trend, the volume of the power source in the traveling and parking brakes gradually increases, and the caliper assembly and the brake disc are axially installed relative to each other. In the existing caliper structure, the sliding shaft is installed in the sliding shaft mounting hole on the bracket, which results in large sliding resistance and large drag torque of the caliper assembly during the working process. Summary of the Utility Model

[0003] In view of the technical problems existing in the background art, the utility model aims to provide a reverse sliding shaft caliper assembly to improve the centroid distribution and effectively reduce the sliding resistance and the drag torque.

[0004] To solve the above technical problems, the utility model adopts the following technical solution: the reverse-mounted brake caliper assembly includes a caliper body and a bracket. Among them, the main sliding shaft and the auxiliary sliding shaft are respectively fixedly connected to both sides of the bracket. The axes of the main sliding shaft and the auxiliary sliding shaft are both parallel to the installation axis of the caliper body. Main installation holes and auxiliary installation holes are respectively provided on both sides of the caliper body. The main installation hole is for the main sliding shaft to pass through, and the auxiliary installation hole is for the auxiliary sliding shaft to pass through. During work, the caliper body slides axially along the main sliding shaft and the auxiliary sliding shaft.

[0005] In this solution, the main sliding shaft and the auxiliary sliding shaft are fixedly connected to the bracket, and as an extension of the bracket, they support both sides of the caliper body, improving the centroid distribution. The axes of the main sliding shaft and the auxiliary sliding shaft are parallel to the installation axis of the caliper body, corresponding to the axial installation relationship between the caliper assembly and the brake disc.

[0006] Preferably, main connection holes and auxiliary connection holes are respectively provided on both sides of the bracket. The main connection holes and the auxiliary connection holes both have a threaded portion and a limiting portion. The threaded portion is used for threaded connection.

[0007] In this solution, the threaded connection ensures the reliability of the connection between the corresponding sliding shaft and the bracket, and the cooperation between the limiting portion and the limiting ring ensures the stability of the corresponding sliding shaft during the working process and the accuracy during the connection process.

[0008] Preferably, both the main installation hole and the auxiliary installation hole are through holes, and dust covers and dust caps are respectively provided at both ends of the main installation hole and both ends of the auxiliary installation hole.

[0009] In this solution, the through-hole design enables the corresponding sliding shaft to fully support the caliper body during the sliding process of the caliper body, and the dust cover and the dust cap cooperate to reliably seal the corresponding installation hole from both ends.

[0010] Preferably, the main sliding shaft is sequentially provided with a first connection head, a first installation groove, and a first axial exhaust groove along the axial direction. The first connection head has a thread. The first installation groove is used for installing a dust cover, and the first installation groove is arranged circumferentially along the main sliding shaft.

[0011] In this solution, the first connection head is used for threaded connection with the threaded part. The dust cover installed in the first installation groove can seal the corresponding installation hole from the inside. The first axial exhaust groove can lead out the air in the corresponding connection hole, reducing the insertion resistance.

[0012] Preferably, the secondary sliding shaft is sequentially provided with a second connection head, a second installation groove, a second axial exhaust groove, and a third installation groove along the axial direction. The second connection head has a thread. The second installation groove is used for installing a dust cover, and the third installation groove is used for installing a rubber sleeve.

[0013] In this solution, the second connection head is used for threaded connection with the threaded part. The dust cover installed in the second installation groove can seal the corresponding installation hole from the inside. The second axial exhaust groove can lead out the air in the corresponding connection hole, reducing the insertion resistance. The rubber ring can increase the overall impact resistance and vibration absorption, thereby improving the performance and reliability of the secondary sliding shaft.

[0014] The beneficial effect of the present utility model is that the centroid distribution of the caliper body remains unchanged during the dynamic process and is consistent with the static centroid distribution, improving the centroid distribution position problem of the caliper assembly. Furthermore, it effectively reduces the sliding resistance and the drag torque, thereby improving the working efficiency and service life of the caliper assembly.

[0026] Reverse installation means that the main sliding shaft and the auxiliary sliding shaft are fixedly connected to the bracket, and forward installation means that the main sliding shaft and the auxiliary sliding shaft are fixedly connected to the pliers body.

[0027] See the appendix Figures 1-3 In the embodiments of this implementation manner, a reverse sliding shaft caliper assembly includes a pliers body 1 and a bracket 2.

[0028] Among them, the main sliding shaft 3 and the auxiliary sliding shaft 4 are respectively fixedly connected to both sides of the bracket 2. The axes of the main sliding shaft 3 and the auxiliary sliding shaft 4 are both parallel to the installation axis of the pliers body 1. Main installation holes and auxiliary installation holes are respectively provided on both sides of the pliers body 1. The main installation holes and the auxiliary installation holes are both through holes. Dust covers 8 and dust caps 9 are respectively provided at both ends of the main installation holes and both ends of the auxiliary installation holes. The main installation hole is for the main sliding shaft 3 to pass through, and the auxiliary installation hole is for the auxiliary sliding shaft 4 to pass through. During operation, the pliers body 1 slides axially along the main sliding shaft 3 and the auxiliary sliding shaft 4.

[0029] In this embodiment, during operation, the clamp body 1 slides circumferentially along the main sliding shaft 3 and the auxiliary sliding shaft 4, which can better fit the brake disc during braking and can adapt to the thermal expansion and contraction of the brake disc. Among them, the through-hole design makes the support area between the clamp body 1 and the corresponding sliding shaft unchanged during the sliding process, so that the centroid distribution of the clamp body 1 remains unchanged during the dynamic process and is consistent with the centroid distribution in the static state.

[0030] See the appendix Figures 3-6 , main connection holes and auxiliary connection holes are correspondingly provided on both sides of the bracket 2. Both the main connection hole and the auxiliary connection hole have a threaded portion 5 and a limiting portion 6. The threaded portion 5 is used for threaded connection. Limiting rings 7 are provided on both the main sliding shaft 3 and the auxiliary sliding shaft 4, and the limiting rings 7 cooperate with the limiting portions 6.

[0031] In this embodiment, the limiting portion 6 can also support the corresponding sliding shaft during the dynamic process. Cooperating with the threaded portion 5, it ensures the stability of the corresponding sliding shaft during the dynamic process.

[0032] See the appendix Figures 5-6 , the main sliding shaft 3 is sequentially provided with a first connection head 10, a first installation groove 11 and a first axial exhaust groove 12 along the axial direction. The first connection head 10 has a thread. The first installation groove 11 is used for installing a dust cover 8. The first installation groove 11 is arranged circumferentially along the main sliding shaft 3. The auxiliary sliding shaft 4 is sequentially provided with a second connection head 13, a second installation groove 14, a second axial exhaust groove 15 and a third installation groove 16 along the axial direction. The second connection head 13 has a thread. The second installation groove 14 is used for installing a dust cover 8. The third installation groove 16 is used for installing a rubber sleeve 17. Both the second installation groove 14 and the third installation groove 16 are arranged circumferentially along the auxiliary sliding shaft 4.

[0033] In this embodiment, in the working state, the auxiliary sliding shaft 4 is in the cutting-out direction. When braking suddenly, it will be affected by inertia and have a reverse acceleration. At this time, the rubber sleeve 17 plays a role in shock absorption and impact reduction. The main sliding shaft 3 is in the cutting-in direction. Since the auxiliary sliding shaft 4 is installed with a rubber sleeve 17, the main sliding shaft 3 does not need to be installed.

[0034] The above is the preferred embodiment of the present invention. It should be noted that the protection scope of the present invention is not limited thereto. For those skilled in the art of this technology, without departing from the technical scope disclosed by the present invention and on the premise of the same inventive concept, several improvements, refinements or equivalent replacements can also be made, which are also regarded as the protection scope of the present invention.
