Abstract

This utility model discloses a front suspension control arm for automobiles, including a ball joint pin connected to the control arm and an oil reservoir cavity inside the control arm. A ball bearing is disposed between the ball joint pin and the oil reservoir cavity. A rotating shaft is rotatably fitted around the inner ring of the ball bearing. The end of the rotating shaft is fixedly connected to the inner wall of the control arm. The ball bearing abuts against the ball joint pin and has several oil delivery grooves. An oil supply channel communicating with the oil reservoir cavity is provided on the outer side of the control arm. A partition plate is fixedly connected inside the oil supply channel, and a piston rod is movably fitted around the inner ring of the partition plate. When the ball joint pin rotates within the ball seat of the control arm, the contact with the ball bearing causes it to rotate around the rotating shaft. During rotation, the rotating shaft carries lubricating oil from inside the oil reservoir cavity to the outer surface of the ball joint pin through the oil delivery grooves, ensuring that the outer surface of the ball joint pin always retains a sufficient amount of lubricating oil, thereby reducing wear and increasing service life.

Description

Technical Field

[0001] This utility model belongs to the field of suspension control arm technology, and particularly relates to the front suspension control arm of automobiles. Background Technology

[0002] The control arm is an indispensable component of the automotive suspension system. In the steering and suspension systems of cars, tractors, and construction machinery, the ball joint assembly is an important technical indicator in control arm technology.

[0003] In existing technology, the ball seat is directly vulcanized and fixed in the ball head pin mounting cavity, resulting in the ball seat and the vehicle suspension control arm body being integrated and inseparable. When the lubricating oil ages, it will increase the wear rate between the ball seat and the ball head pin, accelerate the replacement cycle of the vehicle suspension control arm, and increase maintenance costs. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] The front suspension control arm of an automobile includes a ball joint pin connected to the control arm and an oil reservoir cavity opened inside the control arm. A ball is provided between the ball joint pin and the oil reservoir cavity. The inner ring of the ball is rotatably fitted with a rotating shaft. The end of the rotating shaft is fixedly connected to the inner wall of the control arm. The ball abuts against the ball joint pin and has several oil delivery grooves.

[0006] As a preferred embodiment of the above technical solution, an oil delivery channel communicating with an oil storage chamber is provided on the outer side of the control arm. A partition is fixedly connected inside the oil delivery channel. A piston rod is movably fitted on the inner ring of the partition. A sealing gasket is fixedly fitted on the piston rod. The sealing gasket abuts against the partition. An oil delivery groove is provided on the outer wall of the piston rod.

[0007] As a preferred embodiment of the above technical solution, a second partition plate is fixedly installed inside the oil delivery channel. The second partition plate has several through holes, and one end of the piston rod is movably sleeved in the inner ring of the second partition plate.

[0008] As a preferred embodiment of the above technical solution, an elastic element is fixedly connected to one side of the sealing gasket, and the end of the elastic element away from the sealing gasket is fixedly connected to the partition plate.

[0009] As a preferred embodiment of the above technical solution, a sealing gasket 2 is fixedly connected to the end of the piston rod away from the second partition plate. The sealing gasket 2 cooperates with the piston of the oil delivery channel. A limiting ring that abuts against the sealing gasket 2 is fixedly connected to the oil delivery channel. The limiting ring is located on the side of the sealing gasket 2 away from the piston rod. A transition groove is provided on the side wall of the oil delivery channel. The transition groove is located between the limiting ring and the first partition plate.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. When the ball head pin rotates in the ball seat of the control arm, it will rotate around the axis of rotation due to the contact with the ball. During the rotation, the axis of rotation will bring the lubricating oil in the oil storage chamber into the outer surface of the ball head pin through the oil delivery groove, so that the outer surface of the ball head pin always has a good quality and quantity of lubricating oil, thereby reducing wear and improving service life.

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the front suspension control arm of the car includes a ball joint pin 10 connected to the control arm and an oil reservoir 11 opened inside the control arm. A ball bearing 20 is provided between the ball joint pin 10 and the oil reservoir 11. The inner ring of the ball bearing 20 is rotatably fitted with a rotating shaft 21. The end of the rotating shaft 21 is fixedly connected to the inner wall of the control arm. The ball bearing 20 abuts against the ball joint pin 10 and has several oil delivery grooves 22.

[0020] Specifically, when the ball pin 10 rotates in the ball seat of the control arm, it will cause the ball 20 to rotate around the shaft 21 through the contact with the ball ball 20. During the rotation, the shaft 21 will bring the lubricating oil in the oil storage chamber 11 through the oil delivery groove 22 to the outer surface of the ball pin 10, so that the outer surface of the ball pin 10 always has a good quality and quantity of lubricating oil, thereby reducing wear and improving service life.

[0021] like Figure 2 and Figure 3 As shown, an oil delivery channel 12 communicating with the oil storage chamber 11 is provided on the outer side of the control arm. A partition 30 is fixedly connected inside the oil delivery channel 12. A piston rod 31 is movably sleeved on the inner ring of the partition 30. A sealing gasket 33 is fixedly sleeved on the piston rod 31. The sealing gasket 33 abuts against the partition 30. An oil delivery groove 32 is provided on the outer wall of the piston rod 31.

[0022] Specifically, by setting up the oil delivery channel 12, it is convenient to replenish the oil storage chamber 11 with lubricating oil. When the sealing gasket 33 is away from the partition 30, lubricating oil can be poured in. The lubricating oil enters the oil storage chamber 11 from the oil delivery groove 32 through the partition 30. When the sealing gasket 33 is in contact with the partition 30, it will be impossible to pour lubricating oil into the oil storage chamber 11, and the lubricating oil inside the oil storage chamber 11 will also be unable to flow out.

[0023] like Figure 2 and Figure 3 As shown, a partition plate 35 is fixedly installed inside the oil delivery channel 12. The partition plate 35 has several through holes 36. One end of the piston rod 31 is movably sleeved in the inner ring of the partition plate 35.

[0024] Specifically, by setting the second partition 35, the piston rod 31 can move more smoothly during the movement, preventing it from shifting during the movement. At the same time, lubricating oil will pass through the through hole 36 to both sides of the second partition 35.

[0025] like Figure 3 As shown, an elastic element 37 is fixedly connected to one side of the sealing gasket 33, and the end of the elastic element 37 away from the sealing gasket 33 is fixedly connected to the partition plate 35.

[0026] Specifically, the elastic element 37 uses, but is not limited to, a spring. Through the force of the elastic element 37, the sealing gasket 33 and the partition 30 are kept in contact without any external interference, so as to prevent the lubricating oil inside the oil reservoir 11 from leaking.

[0027] like Figure 3 As shown, a sealing gasket 34 is fixedly connected to the end of the piston rod 31 away from the second partition 35. The sealing gasket 34 cooperates with the piston of the oil delivery channel 12. A limiting ring 13 that abuts against the sealing gasket 34 is fixedly connected to the oil delivery channel 12. The limiting ring 13 is located on the side of the sealing gasket 34 away from the piston rod 31. A transition groove 14 is opened on the side wall of the oil delivery channel 12. The transition groove 14 is located between the limiting ring 13 and the first partition 30.

[0028] Specifically, when the second sealing gasket 34 abuts against the oil delivery channel 12, the first sealing gasket 33 will also abut against the first partition 30, so that the oil delivery channel 12 remains sealed. After the second sealing gasket 34 is pushed to the position of the transition groove 14, the external lubricating oil will pass through the transition groove 14, the oil delivery groove 32, the first partition 30 and the through hole 36 in sequence, and finally enter the interior of the oil storage chamber 11.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
