Description

Technical Field

[0001] The utility model relates to the field of low-noise hydraulic couplers, in particular to a low-noise hydraulic coupler. Background Art

[0002] A hydraulic coupling is a hydraulic transmission device that connects the power source of a generator or motor with a working machine and transmits torque by the change of the liquid momentum. The hydraulic coupling was used in early automotive semi-automatic transmissions and automatic transmissions. The pump wheel of the hydraulic coupling is connected to the flywheel of the engine, and the power is transmitted by the engine crankshaft. Sometimes, the coupling is strictly speaking a part of the flywheel. In this case, the hydraulic coupling is also called a hydraulic flywheel.

[0003] For example, a low-noise hydraulic coupler disclosed in the utility model with authorization announcement number CN219692171U is provided with an oil pipe, an oil dripping hole and a guide plate that cooperate with each other. The lubricating oil is transported into the oil dripping hole through the oil pipe by an automatic oil dripper, so that the lubricating oil drips onto the surface of the guide plate through the oil dripping hole, and the lubricating oil flows through the guide plate to the connection between the bearing and the input shaft and the output shaft, which can play a role in lubricating the bearing. However, during the operation of the current hydraulic coupler, due to its own vibration, the entire coupler will generate a lot of noise during operation, thereby polluting the surrounding environment. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a low-noise hydraulic coupler, which can solve the current hydraulic coupler. The oil pipe, the oil dripping hole and the guide plate cooperate with each other, and the lubricating oil is transported into the oil dripping hole through the oil pipe by an automatic oil dripper, so that the lubricating oil drips onto the surface of the guide plate through the oil dripping hole, and the lubricating oil flows through the guide plate to the connection between the bearing and the input shaft and the output shaft, which can play a role in lubricating the bearing. However, during the operation of the current hydraulic coupler, due to its own vibration, the entire coupler will generate a large noise during operation, thereby causing pollution to the surrounding environment. Technical problem.

[0006] As a preferred technical solution of the utility model, the buffer structure includes a damper and a buffer spring, the bottom of the buffer seat is fixedly connected with the damper, and the surface of the damper is sleeved with a buffer spring.

[0007] As a preferred technical solution of the utility model, a bearing is distributed at the front end of the outer shell, and a dustproof net is distributed on one side of the heat dissipation groove.

[0008] As a preferred technical solution of the utility model, the heat dissipation grooves and the outer shell form an integrated structure, and the heat dissipation grooves are symmetrically distributed along the vertical center line of the outer shell.

[0009] As a preferred technical solution of the present utility model, the grooves are equidistantly distributed along the surface of the sound insulation board, and the grooves and the sound insulation board form an integrated structure.

[0010] As a preferred technical solution of the utility model, the buffer seat is slidably connected to the outer shell through the damper, and the buffer seat is equidistantly distributed along the center point of the outer shell.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. By using the sound insulation board, the groove and the wave sound-absorbing cotton in combination, it is convenient to effectively silence the noise generated by the coupler body when it is working, so as to prevent the noise from affecting the surrounding environment. When the noise diffuses inside the outer shell, the wave sound-absorbing cotton can be used to simply silence the noise, and the sound insulation board can achieve sufficient sound insulation, and the groove can achieve the effect of silencing.

[0013] 2. The combined use of the damper, buffer spring and buffer seat can improve the stability of the coupler body during operation and prevent it from shaking to a large extent during operation, thereby causing more noise. When the damper is subjected to a longitudinal force, it will deform, which can drive the buffer spring to deform as well. Then, the reverse force generated by the deformation of the damper and buffer spring can achieve the purpose of buffering, thereby improving the stability of the coupler body during operation.
