Description

Technical Field

[0001] The utility model belongs to the technical field of split-type hydraulic release bearings, in particular to a high-precision split-type hydraulic release bearing. Background Art

[0002] The hydraulic release bearing is an important component in the automobile clutch. It enables the transmission to shift into gear smoothly. When the driver steps on the clutch pedal, power is transmitted to the clutch master cylinder. The master cylinder outputs oil pressure directly to the hydraulic release bearing. The hydraulic release bearing pushes the active and passive friction plates of the clutch to separate, cutting off the power output of the engine, thereby realizing the clutch function.

[0003] The existing split hydraulic release bearing is composed of components such as a pump body, a cylinder sleeve, a spring, a piston and a bearing. The pump body drives the piston to move through the hydraulic pressure, so that the bearing can push the friction plate of the clutch. However, the current split hydraulic release bearing does not have a bearing dustproof function. During use, external dust will enter the inside of the bearing, causing it to wear or rust, generate noise during rotation, and reduce its rotation accuracy, which is not conducive to people's use.

[0004] To this end, we provide a high-precision split hydraulic release bearing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-precision split hydraulic release bearing. Through the coordinated arrangement of a dustproof component and an automatic oil replenishing component, the problem that the split hydraulic release bearing in the prior art has no bearing dustproof function and external dust can easily enter the interior of the bearing, causing it to wear and affecting its rotation accuracy is solved.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a high-precision split hydraulic release bearing, comprising a pump body, a dustproof component and an automatic oil replenishing component. The inner cavity of the pump body is provided with a piston, the surface of the piston is provided with a spring, the top of the piston is fixedly connected to the inner ring of the bearing, the surface of the inner ring of the bearing is provided with an outer ring of the bearing, a ball is provided between the inner ring of the bearing and the outer ring of the bearing, and the inner cavity of the piston is provided with a cylinder sleeve;

[0008] The dustproof assembly is arranged on the top of the pump body, and includes a fixing ring, the top of which is fixedly connected to a corrugated rubber sleeve, the inner wall of the corrugated rubber sleeve is fixedly connected to the inner ring of the bearing via a fixing rod, and the surface of the outer ring of the bearing is fixedly connected to the impeller;

[0009] The automatic oil replenishing assembly is arranged on the left side of the top of the pump body, and includes an oil storage cylinder. The inner cavity of the oil storage cylinder is provided with a movable plate, and the bottom of the movable plate is provided with a delivery pipe. The top of the delivery pipe passes through the top of the inner ring of the bearing. A sealing ring is fixedly connected to the bottom between the two sides of the inner cavity of the oil storage cylinder, and a sealing plate is provided on the top of the sealing ring.

[0010] The utility model is further configured such that both sides of the top of the sealing ring are fixedly connected with sliding rods, the surfaces of the sliding rods are sleeved with sliding sleeves, and opposite sides of the two sliding sleeves are fixedly connected to the sealing plate.

[0011] The utility model is further configured such that the bottom of the left side of the oil storage cylinder is connected with an oil filling pipe, the left end of the oil filling pipe passes through the outside of the fixing ring, and a one-way valve is sleeved on the surface of the oil filling pipe.

[0012] The utility model is further configured such that a rubber pad is fixedly connected to the bottom of the sealing plate, and the diameter of the rubber pad is larger than the diameter of the hole of the sealing ring.

[0013] The utility model is further configured such that the right side of the pump body is connected to an oil nozzle, and the bottom of the piston is fixedly connected to a rubber ring.

[0016] The utility model is further configured such that the movable plate is made of a composite of a rubber sheet and a steel sheet, and a through hole for use with a delivery pipe is opened on the top of the oil storage cylinder.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model is provided with a dustproof component, which can drive the impeller to rotate when the outer ring of the bearing rotates, and the air inside the corrugated rubber sleeve is discharged through the impeller. The external air enters the corrugated rubber sleeve through the dust filter mesh holes opened on the surface of the fixed ring. By continuously discharging the air inside the corrugated rubber sleeve, a fast-flowing airflow is formed on the surface of the outer ring of the bearing. The airflow can prevent external dust from falling on the surface of the outer ring of the bearing, and avoid dust from contacting the ball and causing wear.

[0019] 2. The utility model is provided with an automatic oil replenishing component. After the pump body drives the piston to move and reset, the inner ring of the bearing drives the delivery pipe and the movable plate to move. The movement of the movable plate allows the lubricating oil inside the oil storage cylinder to pass through the sealing ring and the sealing plate and enter the delivery pipe. The delivery pipe then discharges the lubricating oil to the surface of the ball, thereby realizing automatic oil replenishment to lubricate the ball and prevent it from being worn due to lack of oil.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
