Description

Technical Field

[0001] The utility model relates to the technical field of brakes, and particularly to a main shaft applied to a brake expansion ring. Background Art

[0002] In the prior art, a brake system that cooperates with a main shaft and a brake expansion ring is widely used in various mechanical devices to provide a reliable braking function. However, there are some technical defects in the traditional main shaft during actual use, which affect its performance and reliability.

[0003] First of all, during braking, the main shaft and the brake expansion ring will squeeze and lock each other, and cause shrinkage and torsional deformation. This kind of deformation often causes slight torsion of the main shaft, resulting in unstable braking performance. Due to the tight fit between the main shaft and the brake expansion ring, this torsional deformation is inevitable, thus affecting the stability and accuracy of the entire brake system.

[0004] Secondly, the existing main shafts are usually designed without considering the space for torsional deformation. The fit between the main shaft and the brake expansion ring is often too tight, without providing enough space to accommodate these deformations. This leads to excessive wear and damage of the main shaft and the brake expansion ring under high load or frequent use, further reducing the service life of the brake system.

[0005] In addition, the main shaft and the brake expansion ring in the prior art have unsatisfactory effects when facing complex stress conditions. The main shaft and the brake expansion ring have limitations in providing the necessary frictional force. Especially when the main shaft and the brake expansion ring are locked, they cannot effectively control and disperse stress concentration, resulting in local deformation and fatigue damage.

[0006] In summary, the main shafts in the prior art have technical defects such as torsion caused by torsional deformation, lack of design space for accommodating deformation, and uneven stress dispersion. These problems seriously affect the stability and durability of the brake system. Therefore, an improved design is urgently needed to solve these problems and improve the stability and reliability of the main shaft. Summary of the Invention

[0007] The main object of the utility model is to provide an improved brake main shaft, which can effectively reduce the torsional deformation of the main shaft during the locking process of the brake block. To achieve this purpose, the utility model provides a brake block having a plurality of annular grooves and at least one vertical groove. These grooves are provided on the outer surface of the brake block, wherein the annular grooves are used to enhance the stability of the brake expansion ring, and the vertical grooves provide the necessary space to accommodate the deformation of the brake expansion ring, thereby improving the stability and durability of the brake system, effectively controlling and dispersing stress concentration, and avoiding problems of local deformation and fatigue damage.

[0008] According to the above object, the present utility model provides an improved brake spindle, comprising: a rod body and a brake block. The brake block is annularly arranged on the surface of the rod body and has an inner side and an outer surface, and the inner side is connected to the rod body. The brake block includes: a plurality of first grooves and at least one second groove. The plurality of first grooves are annularly arranged on the outer surface. At least one second groove is arranged on the outer surface, and at least one second groove intersects with each first groove.

[0009] Wherein, each of the first grooves is equally spaced on the outer surface of the brake block.

[0010] Wherein, the depth and width of each of the first grooves are equal.

[0011] Wherein, the annular arrangement direction of each of the first grooves is parallel to the circumferential direction of the brake block.

[0012] Wherein, when there are multiple second grooves, each of the second grooves is equally spaced on the outer surface. And further, the depth and width of each of the second grooves are equal.

[0013] Wherein, at least one second groove is perpendicular to each first groove.

[0014] Wherein, in each of the first grooves, at least one of the first grooves is arc-shaped.

[0015] Wherein, in each of the second grooves, at least one of the second grooves is arc-shaped.

[0016] As described above, when the vehicle actuates the improved brake spindle of the present utility model with a brake expansion ring, the following effects can be achieved:

[0017] (1) Improve stability: Due to the design of the annular grooves and vertical grooves, the stability between the spindle and the brake expansion ring is improved, and the distortion of the spindle during the locking process is reduced.

[0018] (2) Prolong service life: The vertical grooves provide additional space to accommodate the deformation of the spindle, thereby prolonging the service life of the spindle.

[0019] (3) Control stress concentration: The annular grooves and vertical grooves work together to effectively control and disperse stress concentration, avoiding local deformation and fatigue damage.

[0020] (4) Improve durability and reliability: The design of the annular grooves and vertical grooves on the brake block improves the durability and reliability of the spindle under high load or frequent use conditions.

[0021] (5) Reduce wear: The design of the vertical grooves and annular grooves avoids the problem of excessive wear caused by distortion in the traditional brake block design.

[0022] (6) Improve operation efficiency: The design of the annular groove and the vertical groove improves the installation and maintenance convenience of the spindle, and enhances the overall operation efficiency.

[0028] Please refer to Figures 1-2 , Figure 1 It is a side view schematic diagram of the improved brake spindle according to the embodiment provided by the present utility model; Figure 2 It is a three-dimensional schematic diagram of the improved brake spindle according to the embodiment provided by the present utility model. This embodiment provides a spindle 100 that cooperates with a brake expansion ring to complete the braking action. The spindle 100 includes: a rod body 110 and a brake block 120. The brake block 120 is annularly arranged on the surface of the rod body 110 and has an inner side and an outer surface. The inner side is connected to the rod body 110. The brake block 120 further includes: a plurality of first grooves 122 and at least one second groove 124. The plurality of first grooves 122 are annularly arranged on the outer surface of the brake block 120. At least one second groove 124 is arranged on the outer surface of the brake block 120, and at least one second groove 124 intersects with each first groove 122.

[0029] According to another embodiment, each first groove 122 is equally spaced on the outer surface of the brake block 120. In this embodiment, the uniform spacing arrangement of each first groove 122 helps to evenly distribute stress and improve the stability and durability of the spindle 100.

[0030] According to another embodiment, the depth and width of each first groove 122 are equal. In this embodiment, the equal depth and width of each first groove 122 can contribute to stabilizing the stress distribution and improving the structural integrity of the main shaft 100.

[0031] According to yet another embodiment, the circumferential direction of the annular arrangement of each first groove 122 is parallel to the circumferential direction of the brake block 120. In this embodiment, arranging each first groove 122 along the circumferential direction of the brake block 120 helps to maintain the uniform structure of the main shaft 100, improving its stability and durability.

[0032] According to another embodiment, when there are multiple second grooves 124, each second groove 124 is arranged on the outer surface at equal intervals, and the depth and width of each second groove 124 can also be made equal. In this embodiment, the multiple and structurally consistent second grooves 124 contribute to the uniform distribution of stress, improving the stability and durability of the main shaft 100.

[0033] According to yet another embodiment, at least one second groove 124 is arranged perpendicular to each first groove 122. In this embodiment, the perpendicular arrangement helps to provide a better stress dispersion effect, thereby enhancing the structural stability of the main shaft 100 and effectively preventing local deformation and damage caused by stress concentration. In addition, the second groove 124 can also be arranged non-perpendicularly to the first groove 122, for example, intersecting at a certain angle, to meet different stress distribution requirements and structural design requirements.

[0034] According to another embodiment, in each first groove 122, at least one or all of the first grooves 122 have a specific geometric shape, and the geometric shape can be, for example, arc-shaped, V-shaped, U-shaped or trapezoidal. In this embodiment, using the first groove 122 with an arc-shaped groove helps to smooth the stress distribution, reduce the stress concentration phenomenon, thereby enhancing the overall structural stability and durability of the main shaft 100. The arc-shaped groove can provide a more gentle transition, avoiding local stress concentration caused by sharp edges, and thus reducing the risk of fatigue damage. In addition, the arc-shaped groove can also improve the performance of the main shaft 100 under dynamic loads and reduce damage caused by frequent operations. In addition, the arc-shaped groove of the first groove 122 can also be replaced by grooves with other geometric shapes to achieve similar functional effects, such as the V-shaped, U-shaped or trapezoidal grooves mentioned above.

[0035] According to another embodiment, in each of the second grooves 124, at least one or all of the second grooves 124 are arc-shaped. In this embodiment, the second grooves 124 and the first grooves 122 are perpendicular to each other, so that a multi-directional stress dispersion effect can be provided when the brake block 120 is locked. Among them, the second grooves 124 that are arc-shaped grooves can further smooth the stress transition and reduce local stress concentration, thereby improving the stability and durability of the entire main shaft 100. Similarly, the arc-shaped grooves of the second grooves 124 can also be replaced by grooves of other geometric shapes to achieve similar functional effects, such as V-shaped, U-shaped or trapezoidal.

[0036] The rod body 110 and the brake block 120 of the present utility model can be made of corresponding materials according to actual requirements or cost considerations, such as high-strength steel, aluminum alloy or composite materials; or a hardening treatment or an anti-corrosion coating is performed on the outer surface of the brake block 120. However, regardless of any material or processing treatment, the structural features of the main shaft 100 related to the present utility model fall within the scope of the patent application of the present utility model.

[0037] The above is only an example to illustrate the preferred embodiments of the present utility model, and is not intended to limit the scope of implementation. Any simple substitution and equivalent change made according to the scope of the patent application of the present utility model and the content of the patent specification fall within the scope of the patent application of the present utility model.
