Description

Technical Field

[0001] This utility model relates to the field of brake technology, and more specifically, to an integrated through-shaft hydraulic motor brake. Background Technology

[0002] The conventional MS11 internal curve radial piston motor uses a segmented shaft brake, which is cumbersome to install and cannot guarantee the coaxiality of the output shaft and brake shaft. During use, the poor coaxiality of the segmented shaft brake easily leads to accelerated wear of the friction plates, reducing the brake's service life and causing oil leakage, resulting in poor overall performance. Therefore, this invention proposes an integrated through-shaft hydraulic motor brake. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an integrated through-shaft hydraulic motor brake, which has the characteristics of compact structure and complete functionality.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The utility model relates to an integrated through-shaft hydraulic motor brake, including a brake seat, an integrated brake shaft rotatably connected to the brake seat, a dynamic friction plate on the integrated brake shaft and a static friction plate on the brake seat between the integrated brake shaft and the brake seat, a piston chamber with one end connected to the outside and the other end into which the integrated brake shaft extends, a brake rear cover provided at the opening of the piston chamber, a brake piston slidably connected inside the piston chamber, a disc spring with one end abutting against the brake piston and the other end abutting against the brake rear cover between the brake piston and the brake rear cover, and a braking element for abutting against the dynamic friction plate or the static friction plate on the brake piston.

[0005] The present invention is further configured such that a buffer chamber filled with liquid is provided between the brake piston and the brake seat.

[0006] The present invention is further configured such that a sealing ring is provided on the brake piston between the brake piston and the brake seat.

[0007] The present invention is further configured such that: a double sealing ring is provided between the brake piston and the brake seat, which is provided on the brake seat.

[0008] The present invention is further configured such that a vent plug is provided on the brake cover.

[0009] The present invention is further configured such that the number of disc springs is one.

[0010] In summary, this utility model has the following beneficial effects:

[0011] 1. By optimizing the motor brake shaft structure, a compact, integrated through-shaft hydraulic motor brake is designed, which can effectively increase the service life of the friction pads, reduce brake oil leakage, and improve brake performance during use.

[0012] 2. A specially designed brake piston module can achieve braking function while retaining a fluid-filled buffer chamber between the brake piston and the brake seat. At the same time, it achieves double sealing between the brake piston and the brake seat, making the brake structure compact and its functionality complete.

[0013] 3. It has been widely used in mining engineering vehicles, with broad applications and strong adaptability. Attached Figure Description

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] Example 1

[0018] See Figure 1 As shown, the integrated through-shaft hydraulic motor brake involved in this embodiment includes a brake seat 1, an integrated brake shaft 2 rotatably connected to the brake seat 1, a dynamic friction plate 3 provided on the integrated brake shaft 2 and the brake seat 1, and a static friction plate 4 provided on the brake seat 1. The brake seat 1 has a piston chamber 5 with one end connected to the outside and the other end for the integrated brake shaft to extend into. The opening of the piston chamber 5 is provided with a brake rear cover 6. A brake piston 7 is slidably connected in the piston chamber 5. A disc spring 8 is provided between the brake piston 7 and the brake rear cover 6, with one end abutting against the brake piston and the other end abutting against the brake rear cover. The brake piston 7 is provided with a brake element 9 for abutting against the dynamic friction plate or the static friction plate.

[0019] Furthermore, the brake cover 6 is provided with a vent plug 13.

[0020] In this embodiment, the integrated brake shaft can be installed inside the motor brake to achieve the braking function, while ensuring the coaxiality of the motor output shaft and the brake shaft, making the motor structure compact.

[0021] The brake rear cover 6 is designed to work in conjunction with the brake piston 9, so that the disc spring 8 is pressed between the brake rear cover 6 and the brake piston 9.

[0022] Example 2

[0023] See Figure 1 As shown, the integrated through-shaft hydraulic motor brake involved in this embodiment is further configured, based on embodiment 1, to have a buffer chamber 10 filled with liquid between the brake piston 7 and the brake seat 1.

[0024] In this embodiment, by opening the buffer chamber 10 and filling it with oil, the brake piston 7 does not directly contact the brake seat 1, and can be used as a buffer when subjected to axial force.

[0025] Example 3

[0026] See Figure 1 As shown, the integrated through-shaft hydraulic motor brake involved in this embodiment is further configured, based on embodiments 1 and 2, to have a first sealing ring 11 provided on the brake piston and a second sealing ring 12 provided on the brake seat between the brake piston 7 and the brake seat 1.

[0027] In this embodiment, the combination of a primary sealing ring 11 and a secondary sealing ring 12 enhances the sealing effect.

[0028] The integrated through-shaft hydraulic motor brake involved in this utility model optimizes the internal structure of the motor brake, resulting in a compact integrated through-shaft hydraulic motor brake that can effectively brake during use, reduce abnormal wear of the friction pads, and improve the service life of the friction pads. A specially designed brake piston achieves braking while retaining a fluid-filled buffer chamber between the brake piston and the brake seat, making the motor structure compact and functionally complete. It has been widely used in mining engineering vehicles, demonstrating broad application, strong adaptability, comprehensive overall functionality, and high practicality.
