[0026] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the drawings.
[0027] The present application provides a low-resistance automobile steering ball socket lining structure as shown in Figures 1-4 The present application provides a low-resistance automobile steering ball socket lining structure as shown in
[0028] Specifically, the inner lining assembly 3 includes a spherical shell 31, the spherical shell 31 is fixed on the outer surface of the steering ball head 1, the outer surface of the spherical shell 31 is provided with a plurality of installation ring grooves 32, a plurality of balls 33 are installed in the plurality of installation ring grooves 32, and the groove body of the installation ring groove 32 is further provided with an oil storage groove 34, and the ball 33 is attached to the inner wall of the steering ball socket 2.
[0029] In this embodiment, the spherical shell 31 is tightly fixed on the outer surface of the steering ball head 1 by a suitable method, so as to ensure that the spherical shell 31 and the steering ball head 1 do not move relative to each other during vehicle driving.
[0030] Specifically, the plurality of balls 33 are respectively installed into the plurality of installation ring grooves 32 on the outer surface of the spherical shell 31. Since the groove section shape of the installation ring groove 32 is arc-shaped and the overall size exceeds half a circular arc, the ball 33 can be well wrapped, so that the ball 33 can be kept in a relatively stable position in the installation ring groove 32 and is not easy to fall off.
[0031] Specifically, the oil storage grooves 34 are arranged on both sides of the groove body of the installation ring groove 32, the overall shape of the oil storage groove 34 is annular, the two sides of the opening extend to the center position, and the inside is arc-shaped. During installation, it is ensured that the arrangement direction of the oil storage groove 34 on both sides of each group of installation ring grooves 32 is consistent with the installation direction of the ball 33, so that the lubricant can better act on the ball 33 and the inner wall of the steering ball socket 2 when the steering ball head 1 rotates.
[0032] Referring to Figures 2-4 , the plurality of installation ring grooves 32 are installed on the outer wall of the spherical shell 31 and are uniformly arranged from top to bottom, and the overall shape is annular. The groove section shape of the installation ring groove 32 is arc-shaped, and the overall size exceeds half a circular arc, that is, it is wrapped above the center point of the ball 33. The oil storage groove 34 is arranged on both sides of the installation ring groove 32, and the overall shape is also annular.
[0033] Specifically, the two sides of the opening of the oil storage groove 34 extend to the center position, that is, the opening is smaller than the internal size, and the inside is arc-shaped. The arrangement direction of the oil storage groove 34 on both sides of each group of installation ring grooves 32 is consistent with the installation direction of the ball 33.
[0034] Specifically, the steering ball socket 2 is provided with a ball head mounting port 21 at one end and an extension connector 22 at the other end. The dust cover 4 is installed at the ball head mounting port 21 of the end of the steering ball socket 2, and the handle portion of the steering ball head 1 is arranged inside the dust cover 4.
[0035] Specifically, the dust cover 4 is provided with openings at both ends, and the overall shape is a multi-pleated rubber cover.
[0036] In this embodiment, the steering ball head 1 with the installed lining assembly 3 is placed into the steering ball socket 2, so that the ball 33 is attached to the inner wall of the steering ball socket 2. The ball head mounting port 21 at one end of the steering ball socket 2 is used to accommodate the steering ball head 1, and the extension connector 22 at the other end is used to connect with other parts of the vehicle steering system.
[0037] Specifically, the dust cover 4 is installed at the ball head mounting port 21 of the end of the steering ball socket 2, so that the handle portion of the steering ball head 1 is arranged inside the dust cover 4. The dust cover 4 is provided with openings at both ends, and the overall shape is a multi-pleated rubber cover. During installation, it is ensured that the dust cover 4 is tightly attached to the handle portion of the steering ball head 1 and the ball head mounting port 21 of the steering ball socket 2, so as to prevent dust, impurities and the like from entering the inside of the steering ball socket 2.
[0038] Specifically, the mounting ring groove 32 and the oil storage groove 34 are both made of elastic rubber, and the bottom of the mounting ring groove 32 does not contact the outer surface of the spherical shell 31.
[0039] In this embodiment, during the steering process of the vehicle, when the steering ball head 1 rotates relative to the steering ball socket 2, the ball 33 rolls between them, converting traditional sliding friction into rolling friction. The friction coefficient of rolling friction is much smaller than that of sliding friction, thereby effectively reducing the resistance during steering, making it easier for the driver to operate the steering wheel.
[0040] Specifically, the lubricant stored in the oil storage groove 34 will gradually release onto the contact surface between the ball 33 and the inner wall of the steering ball socket 2 during the rotation of the steering ball head 1, forming a uniform lubricating film. This not only further reduces the friction coefficient and friction, but also prevents excessive wear of the ball 33 and the inner wall of the steering ball socket 2 due to friction, prolonging the service life of the components.
[0041] In this embodiment, multiple mounting ring grooves 32 are evenly arranged on the outer wall of the spherical shell 31 from top to bottom, and the balls 33 are evenly distributed around the steering ball head 1. When the steering ball head 1 rotates in the steering ball socket 2, it can be uniformly supported, avoiding steering deviation or shaking due to uneven force, improving the stability and accuracy of steering. Especially in high-speed driving or emergency avoidance situations, it can ensure that the vehicle steers accurately according to the driver's intention, enhancing the safety of driving.
[0042] Specifically, the special design of the mounting ring groove 32 can ensure the stability of the ball 33 in the mounting ring groove 32, preventing the ball 33 from shifting or falling off during steering, further ensuring the reliability and stability of the steering system.
[0043] In this embodiment, the dust cover 4 can effectively block dust, moisture and other impurities from entering the inside of the steering ball socket 2. During vehicle driving, especially in harsh road conditions or environments, such as muddy roads, dusty weather, etc., the dust cover 4 can protect the surface of the ball 33, the steering ball head 1 and the steering ball socket 2 from being contaminated and eroded by impurities, maintain the normal operation of the steering system, and prolong its service life.
[0044] Specifically, the design of the oil storage groove 34 extending from both sides of the opening to the center position makes the opening smaller than the internal size, which can prevent impurities from entering the oil storage groove 34 to some extent, ensuring the cleanliness and effectiveness of the lubricant, thereby ensuring the durability of the lubrication effect.
[0045] In the embodiment, the mounting ring groove 32 and the oil storage groove 34 are made of elastic rubber material, and the bottom of the mounting ring groove 32 is not in contact with the outer surface of the spherical shell 31. When the vehicle runs on a bumpy road, the steering system will be subjected to a large impact force, at this time, the elastic rubber material of the mounting ring groove 32 and the oil storage groove 34 can produce a certain elastic deformation, absorb and disperse part of the impact force, and play a buffering role. This not only protects the steering ball head 1, the ball 33 and the steering ball socket 2 and other components from being damaged, but also improves the driving comfort.
[0046] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for those skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
