Description

Technical Field

[0001] This utility model belongs to the field of steering gear technology, and specifically relates to a steering gear inclined bracket with a buffer function. Background Technology

[0002] With the development of automotive technology, steering gear brackets are now required to have EA (Emergency Amplification) functionality, which means absorbing side impacts. Therefore, steering gear brackets with buffering capabilities are needed.

[0003] Currently, Chinese utility model patent CN218662006U discloses a car steering gear angle bracket with a buffer function. This patent uses a spring to buffer the lateral movement of the bracket. However, because the spring has a rounded head that contacts the sleeve surface, when the bracket moves laterally, the rotating rod compresses one side of the spring while the other side springs back. Since the rounded head lacks a limiting structure, it easily slides to the sides rather than up and down on the sleeve surface, causing the rounded head to shift position and affecting the buffering effect. Furthermore, direct installation is cumbersome. This patent has multiple mounting holes for bolts, but it cannot install multiple bolts at once; each bolt must be installed individually, resulting in low installation efficiency and making it inconvenient for quick installation of the steering gear angle bracket. Utility Model Content

[0004] The purpose of this utility model is to provide a steering gear inclined bracket with a buffer function. Its advantages are that it limits the sliding of the round head of the spring, prevents it from shifting to both sides on the sleeve surface, and facilitates the synchronous installation of multiple bolts, thereby improving installation efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steering gear inclined bracket with a buffer function, including an upper support and a lower support, wherein rolling balls are rotatably connected inside the upper support and the lower support, and rotating rods are welded to the ends of the two rolling balls that are close to each other. Spring plates are respectively welded to the interior of the upper support and the lower support on both sides of the two rotating rods. A ball head is welded to the end of the spring plate that is close to the rotating rod. Extension plates are welded to the surface of the two rotating rods, and an arc-shaped groove that is slidably connected to the ball head is opened between the two extension plates.

[0006] Using the above technical solution, when lateral vibration is generated by the support, the ball joint slides on the surface of the rotating rod using the arc groove. Simultaneously, the extension plate limits the two sides of the ball joint, ensuring it slides vertically on the rotating rod surface. This prevents lateral sliding and positional displacement, guaranteeing effective lateral vibration damping for the steering gear. By rotating the ring gear on the rotating ring surface, all gears mesh simultaneously, causing the bolts on the upper and lower supports to rotate uniformly and engage with the threaded holes for installation. This eliminates the need to rotate each bolt individually, improving the installation efficiency of the steering gear's inclined support.

[0007] The present invention is further configured such that: a bolt rod is rotatably connected through the ends of the upper support and the lower support that are far apart from each other; a gear is welded to the end of the bolt rod near the rotating rod; a rotating ring is rotatably connected inside the upper support and the lower support; and a ring gear meshing with the gear is fixedly sleeved on the surface of the rotating ring.

[0008] By adopting the above technical solution, the bolt rods on the upper and lower supports are rotated in unison and engaged with the screw holes for installation, eliminating the need to rotate the bolt rods one by one, thus improving the installation efficiency of the steering gear inclined bracket.

[0009] The present invention is further configured such that a rubber pad is fixedly connected to the side of the spring sheet away from the rotating rod.

[0010] By adopting the above technical solution, one end of the spring sheet is in contact with the upper or lower support through a rubber pad, thereby further improving the damping and buffering effect of the spring sheet on lateral vibration force.

[0011] The present invention is further configured such that: a dust cover is fixedly sleeved at one end of the upper support and the lower support that are close to each other, and a pressure balancing valve is fixedly connected to one side of the surface of the dust cover.

[0012] By adopting the above technical solution, dust covers can be installed to protect the interior of the upper and lower supports, preventing dust and moisture from entering. Simultaneously, a pressure balancing valve is installed to discharge internal air and re-draw air in after deformation between the upper and lower supports, thus balancing the internal air pressure of the two supports.

[0013] The present invention is further configured such that: a spring damper is bolted to one end of the two rotating rods that are close to each other, and a plastic sleeve is fitted on the surface of the spring damper and fixedly connected to the rotating rod.

[0014] By adopting the above technical solution, the vertical vibration force between the upper and lower supports is transmitted to the spring damper through the rotating rod, thereby using the spring damper to dampen and buffer the vertical vibration of the steering gear.

[0015] The present invention is further configured such that: both the upper support and the lower support are rotatably connected to ball bearings that are slidably connected to the inner surface of the rotating ring.

[0016] By adopting the above technical solution, the friction of the rotating ring is reduced and the rotational stability of the rotating ring is improved by the rotation of the balls inside the upper and lower supports.

[0017] The present invention is further configured such that: the upper support and the lower support are rotatably connected to a hexagonal screw head welded with a gear on the side of each other.

[0018] Using the above technical solution, the bolt rod is installed synchronously by rotating the hexagonal screw head to drive the gear to rotate.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. When lateral vibration is generated by the support, the ball joint slides on the surface of the rotating rod using the arc groove, while the extension plate limits the two sides of the ball joint, so that the ball joint slides vertically on the surface of the rotating rod. This prevents the ball joint from sliding to the sides on the surface of the rotating rod and causing positional displacement, thus ensuring the buffering effect on the lateral vibration of the steering gear;

[0021] 2. By rotating the ring gear on the surface of the rotating ring, all gears mesh simultaneously, thereby driving the bolt rods on the upper and lower supports to rotate uniformly and engage with the threaded holes for installation. This eliminates the need to rotate the bolt rods one by one, improving the installation efficiency of the steering gear inclined bracket. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 , Figure 3 A steering gear inclined bracket with a buffer function includes an upper support 1 and a lower support 2. Rolling balls 3 are rotatably connected inside both the upper support 1 and the lower support 2. Rotating rods 4 are welded to the ends of the two rolling balls 3 that are close to each other. Spring plates 7, respectively welded to the interior of the upper support 1 and the lower support 2, are provided on both sides of the two rotating rods 4. Ball heads 8 are welded to the ends of the spring plates 7 near the rotating rods 4. Extension plates 9 are welded to the surfaces of both rotating rods 4. An arc-shaped groove 10, which slides between the two extension plates 9, is provided to slidably connect with the ball heads 8. When lateral vibration occurs through the support, the ball heads 8 slide on the surface of the rotating rods 4 using the arc-shaped groove 10. Simultaneously, the extension plates 9 limit the movement of the ball heads 8 on both sides, ensuring that the ball heads 8 slide vertically on the surface of the rotating rods 4. This prevents lateral sliding on the surface of the rotating rods 4 from causing positional displacement, thus ensuring a buffering effect against lateral vibration of the steering gear.

[0030] refer to Figure 2 A rubber pad 15 is fixedly connected to the side of the spring plate 7 away from the rotating rod 4. The rubber pad 15 contacts one end of the spring plate 7 with the upper support 1 or the lower support 2, thereby further improving the damping and buffering effect of the spring plate 7 on lateral vibration force.

[0031] refer to Figure 1 , Figure 2 A dust cover 16 is fixedly fitted onto one end of the upper support 1 and the lower support 2 that are close to each other. A pressure balancing valve 17 is fixedly connected to one side of the surface of the dust cover 16. By installing the dust cover 16, the interior of the upper support 1 and the lower support 2 can be protected to prevent dust and moisture from entering. At the same time, the pressure balancing valve 17 can discharge internal air after deformation between the upper support 1 and the lower support 2 and can also draw in air again to balance the internal air pressure of the upper support 1 and the lower support 2.

[0032] refer to Figure 2 Two rotating rods 4 are bolted to one end of each other with a spring damper 5. A plastic sleeve 6 is fitted onto the surface of the spring damper 5 and is fixedly connected to the rotating rod 4. The vertical vibration force between the upper support 1 and the lower support 2 is transmitted to the spring damper 5 through the rotating rod 4, so that the spring damper 5 can be used to dampen and buffer the vertical vibration of the steering gear.

[0033] Brief description of the usage process: By installing the upper support 1 on the steering gear and the lower support 2 on the vehicle structure, when vertical vibration forces are generated between the upper support 1 and the lower support 2, the vibration force can be buffered by the spring damper 5. Then, when lateral vibration forces are generated between the upper support 1 and the lower support 2, one end of the rotating rod 4 rotates inside the upper support 1 or the lower support 2 via the rolling ball 3, thereby pushing the ball head 8 to slide on the surface of the rotating rod 4, and using the spring plate 7 to buffer the lateral vibration force. At the same time, the ball head 8 slides on the surface of the rotating rod 4 through the arc groove 10, and the extension plate 9 limits the two sides of the ball head 8, so that the ball head 8 slides vertically on the surface of the rotating rod 4, preventing the ball head 8 from sliding to the sides on the surface of the rotating rod 4 and causing positional displacement when the rotating rod 4 compresses the spring plate 7.

[0034] Example 2:

[0035] refer to Figure 1 , Figure 2 , Figure 4 A steering gear slant bracket with a buffer function is disclosed. Bolt rods 11 are rotatably connected to the ends of upper support 1 and lower support 2, which are located away from each other. A gear 12 is welded to the end of the bolt rod 11 near the rotating rod 4. A rotating ring 13 is rotatably connected inside the upper support 1 and lower support 2. A ring gear 14, meshing with the gear 12, is fixedly sleeved on the surface of the rotating ring 13. By rotating the ring gear 14 on the surface of the rotating ring 13, all gears 12 mesh simultaneously, thereby driving the bolt rods 11 on the upper support 1 and lower support 2 to rotate uniformly and engage with the threaded holes for installation. This eliminates the need to rotate each bolt rod 11 individually, improving the installation efficiency of the steering gear slant bracket.

[0036] refer to Figure 2 Both the upper support 1 and the lower support 2 are rotatably connected to ball bearings 18 that are slidably connected to the inner surface of the rotating ring 13. The ball bearings 18 rotate inside the upper support 1 and the lower support 2, thereby reducing the frictional force of the rotating ring 13 and improving the rotational stability of the rotating ring 13.

[0037] refer to Figure 1 , Figure 2 Both the upper support 1 and the lower support 2 have hexagonal screw heads 19 welded to the gear 12 rotatably connected to their respective sides. By rotating the hexagonal screw heads 19, the gear 12 is rotated, thereby synchronously installing the bolt rod 11.

[0038] Brief description of the usage process: By rotating gear 12 and engaging ring gear 14, the rotating ring 13 is driven to rotate inside the upper support 1 or lower support 2. Then, the rotating ring 13, through the synchronous engagement of ring gear 14 and all gears 12 of the upper support 1 or lower support 2, drives the bolt rods 11 on the upper support 1 and lower support 2 to rotate uniformly. When the bolt rods 11 are inserted into the corresponding screw holes of the steering gear or automotive structure, they can be simultaneously threaded into the screw holes without having to rotate each bolt rod 11 individually.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
