Description

Technical Field

[0001] This utility model relates to the field of hydraulic release bearing technology, and more specifically, to a controllable pressure hydraulic release bearing. Background Technology

[0002] Hydraulic release bearings are key components in modern mechanical transmission systems, especially automotive clutch systems. Their basic principle is to drive the internal actuator of the bearing through externally input hydraulic pressure, generating axial thrust to control the disengagement and engagement of the clutch. Compared with traditional mechanical cable or lever mechanisms, hydraulic release bearings have significant advantages such as easy operation, flexible arrangement, and high transmission efficiency. They are widely used in the clutch control systems of manual transmissions, dual-clutch transmissions, and some automatic transmissions.

[0003] However, the working pressure of existing conventional hydraulic release bearings is mainly provided and determined by the external hydraulic master cylinder and pipeline system connected to them during application. The bearing itself does not have the ability to adjust the working pressure. When it is necessary to adjust the thrust applied to the clutch release mechanism according to different working conditions, it is usually necessary to depressurize the entire external hydraulic system, disassemble the pipeline joints, replace the master cylinder of different sizes, and then reassemble and add oil, bleed air, etc. This process consumes a lot of time and effort, and cannot guarantee the adjustment accuracy and response speed.

[0004] In view of this, we propose a controllable pressure hydraulic release bearing. Utility Model Content

[0005] 1. Technical problems to be solved

[0016] Preferably, eight locking grooves are provided on the fixed frame, and the eight locking grooves are arranged in an equiangular array along the circumference of the drive rod. The locking grooves are used to lock the adjusting plates at different angles inside the oil pipeline.

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1. This utility model realizes the direct adjustment of the working pressure of the hydraulic release bearing by means of the adjustment component set on the oil supply pipe. The user only needs to operate the drive rod to drive the adjustment plate to rotate, so as to change the oil circuit opening and adjust the input oil pressure. There is no need to disassemble the hydraulic pipeline or drain the oil, which simplifies the cumbersome disassembly and assembly process required for the traditional hydraulic release bearing pressure adjustment, and improves the convenience of operation and maintenance efficiency.

[0020] 2. This utility model provides a reliable gear locking function after adjustment by setting a locking component. When the adjustment plate is rotated to the target angle, the locking rod automatically engages with the locking groove under the action of the spring, forming a mechanical stop, which effectively resists accidental displacement caused by vibration or external force, and ensures the long-term stability of the set pressure parameters under complex working conditions.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] A controllable pressure hydraulic release bearing includes a hydraulic release bearing body 1. Multiple mounting seats 12 are fixedly connected to the bottom of the hydraulic release bearing body 1. Each mounting seat 12 has a mounting groove 13. A connecting channel 14 is fixedly connected to the hydraulic release bearing body 1, penetrating the inner cavity of the hydraulic release bearing body 1, and is used to transmit oil pressure to an actuator. An exhaust port 15 and an oil inlet 16, both connected to the hydraulic release bearing body 1, are fixedly connected to the connecting channel 14. An oil supply pipe 17 is connected to the oil inlet 16, and an adjusting component 2 is provided on the oil supply pipe 17 for adjustment. Component 2 is equipped with a locking component 3; the adjusting component 2 is used to adjust the oil delivery of the oil supply pipe 17; the locking component 3 is used to lock the adjusting component 2 after adjustment. In this way, the pressure regulating mechanism and locking device are directly integrated into the oil supply pipe 17 of the oil inlet 16 near the hydraulic release bearing body 1, which ensures that the pressure regulating function is an inherent and easy-to-operate component of the bearing system itself, without the need to modify or disassemble the main circuit of the external hydraulic system. This solves the problem that the pressure regulation of traditional hydraulic release bearings requires disassembling the pipeline or replacing the main cylinder components, and realizes the rapid adjustment of the bearing hydraulic pressure.

[0031] Specifically, the regulating component 2 includes a rotating rod 22 rotatably connected to the oil supply pipe 17 and an regulating plate 23 fixedly connected to the rotating rod 22. The size of the regulating plate 23 is adapted to the size of the inner wall of the oil supply pipe 17. With this configuration, the rotating rod 22 drives the regulating plate 23 to rotate within the oil supply pipe 17, so that the opening formed with the pipe wall when it rotates to different angles can precisely control the flow rate, thereby realizing the adjustment of the oil pressure input to the bearing.

[0032] Secondly, a sealing ring 24 is fixedly connected to the oil supply pipe 17 at the rotational connection between the rotating rod 22 and the oil supply pipe 17. The sealing ring 24 can ensure the pressure stability and sealing of the hydraulic system, prevent pressure loss and functional failure caused by oil leakage, and improve the stability of the device operation.

[0033] Furthermore, a mounting bracket 21 is fixedly connected to the oil pipeline 17, and a rotating rod 22 is rotatably connected to the mounting bracket 21. A drive rod 26 is rotatably connected to the mounting bracket 21. A first bevel gear 27 and a second bevel gear 28 are fixedly connected to the rotating rod 22 and the drive rod 26, respectively. The first bevel gear 27 and the second bevel gear 28 are meshed together. This arrangement makes the mounting bracket 21 a stable support base. The rotational motion of the drive rod 26 is converted into the rotational motion of the rotating rod 22 through the bevel gear set, making the rotation of the adjusting plate 23 easier to adjust.

[0034] In addition, a fixed bracket 25 is fixedly connected to the mounting bracket 21, and a drive rod 26 is rotatably connected to the fixed bracket 25. An adjustment plate 29 is fixedly connected to the drive rod 26. The adjustment plate 29 is used to install the locking component 3. The setting of the adjustment plate 29 makes the rotation of the drive rod 26 more convenient, and can also cooperate with the fixed bracket 25 to provide an installation position for the locking component 3.

[0035] The locking assembly 3 includes a locking rod 31 elastically connected to the adjusting disc 29 by a spring 33 and multiple locking slots 32 formed on the fixing frame 25. The dimensions of the multiple locking slots 32 are adapted to the dimensions of the locking rod 31. This arrangement allows the locking rod 31, pre-tightened by the spring 33, and the locking slots 32 on the fixing frame 25 to form a positioning mechanism with a self-locking function. When the user rotates the drive rod 26 to the required locking angle, they only need to overcome the force of the spring 33 to pull the locking rod 31. After rotating to the target position, the user releases the locking rod 31, and the force of the spring 33 will push the locking rod 31 to automatically engage with the nearest matching locking slot 32. This arrangement can effectively resist the displacement caused by vibration during vehicle operation, ensuring that the pressure adjustment state will not change easily and guaranteeing the stability of the pressure setting.

[0036] Furthermore, eight locking slots 32 are provided on the fixed frame 25, and the eight locking slots 32 are arranged in an equiangular array along the circumference of the drive rod 26. The locking slots 32 are used to lock the adjusting plate 23 at different angles in the oil pipe 17. The eight evenly distributed locking slots 32 on the fixed frame 25 divide the rotation space into eight 45° intervals, providing sufficient adjustment accuracy to meet the pressure adjustment requirements under most working conditions. Each locking slot 32 precisely corresponds to a specific angular position of the drive rod 26, realizing reliable fixation of the pressure adjustment state, preventing the adjusting plate 23 from rotating on its own during operation, and ensuring that the final pressure output is stable at the set value.

[0037] Working principle:

[0038] When the working pressure of the hydraulic release bearing needs to be adjusted, the operator holds the adjusting plate 29 at the end of the drive rod 26 and rotates it. The rotation of the drive rod 26 is transmitted to the first bevel gear 27 through the second bevel gear 28 fixed to it, which drives the rotating rod 22 to rotate inside the oil pipe 17. The adjusting plate 23 fixed on the rotating rod 22 rotates synchronously with the rotating rod 22. The size of the gap formed between the adjusting plate 23 and the inner wall of the oil pipe 17 changes accordingly. When the angle is increased, the flow gap becomes larger, the oil flow resistance decreases, and the pressure of the input bearing decreases. When the angle is decreased, the flow gap becomes smaller, the oil flow resistance increases, and the pressure of the input bearing increases. After adjusting to the target pressure, the operator releases the locking rod 31. Under the action of the spring 33, the locking rod 31 automatically embeds into the corresponding locking groove 32 on the fixing frame 25, reliably locking the opening of the drive rod 26 and the internal adjusting plate 23.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
