Technical Field

[0001] The utility model relates to the technical field of automobile parts, and specifically relates to an efficient steering transmission mechanism for automobiles. Background Art

[0002] During the driving process of an automobile, the steering transmission mechanism plays a very important role. It can transmit the force and motion output by the steering gear to the steering knuckles on both sides of the steering axle, so that the steering wheels on both sides deflect. In this way, the steering transmission mechanism can ensure that when the automobile steers, the relative sliding between the wheels and the ground is as small as possible. There is a transmission structure installed in the efficient steering transmission mechanism for automobiles, which requires workers to manually lubricate it regularly to ensure smooth meshing and make the steering more flexible. By manually lubricating, the labor intensity is increased, and the disassembly and assembly structure of the transmission mechanism and the steering wheel is cumbersome, resulting in inconvenient maintenance. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model

[0003] The purpose of the utility model is to provide an efficient steering transmission mechanism for automobiles, so as to solve the problems that the existing efficient steering transmission mechanism for automobiles does not have a self-lubricating function and is not convenient for quick disassembly and assembly mentioned in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An efficient steering transmission mechanism for automobiles, including a chassis, a ram rod and a second return spring. Both sides of the top of the chassis are movably connected with steering parts through rotating shafts, and moving wheels are connected to one side of each steering part. One end of each steering part is movably connected with a movable rod, and one end of each movable rod is movably connected with a moving plate through a rotating shaft. A rack is installed on the outer wall of one end of the moving plate, and a gear is meshed and installed at one end of the rack. A rotating rod is connected above the gear, and a steering wheel is installed inside the upper part of the rotating rod. A locking sleeve is installed on the outer wall of the upper part of the rotating rod. A ram rod is installed on the outer wall of the lower part of the rotating rod, and an oil box is connected to the outer wall of the chassis above the ram rod. An oil hole is provided at the bottom end of the oil box, and an oil plug is installed inside the oil hole.

[0005] Preferably, a limiting groove is provided on the outer wall of the chassis at one end of the moving plate, and both sides of the outer wall of one end of the moving plate are movably connected with the limiting groove through limiting wheels.

[0006] Preferably, a sealing gasket is installed on the outer wall above the oil plug, and a top plate is connected to the top end of the oil plug.

[0007] Preferably, damping devices are connected to both sides of the bottom end of the top plate, and first return springs are installed on the outer walls of the damping devices.

[0008] Preferably, an internal thread is provided on the inner wall below the locking sleeve, and an external thread is provided on the outer wall above the rotating rod. A threaded connection structure is formed between the locking sleeve and the rotating rod.

[0009] Preferably, moving rods are movably connected to the outer walls on both sides of the rotating rod, and locking blocks are connected to one ends of the moving rods. Locking grooves matching the locking blocks are provided on the outer wall of the steering wheel.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1 - 4 , an efficient steering transmission mechanism for an automobile, including a chassis 7, a ramming rod 12 and a second return spring 22. Both sides of the top end of the chassis 7 are movably connected with a steering member 1 through a rotating shaft, and a moving wheel 6 is connected to one side of each steering member 1. One end of each steering member 1 is movably connected with a movable rod 2, and one end of each movable rod 2 is movably connected with a moving plate 4 through a rotating shaft. A rack 5 is installed on the outer wall of one end of the moving plate 4, and a gear 3 is meshed and installed at one end of the rack 5. A rotating rod 9 is connected above the gear 3, and a steering wheel 8 is installed inside the upper part of the rotating rod 9. A locking sleeve 18 is installed on the outer wall of the upper part of the rotating rod 9, and a ramming rod 12 is installed on the outer wall of the lower part of the rotating rod 9. The outer wall of the chassis 7 above the ramming rod 12 is connected with an oil box 10. An oil hole 14 is arranged at the bottom end of the oil box 10, and an oil plug 13 is installed inside the oil hole 14;

[0021] A limiting groove is arranged on the outer wall of the chassis 7 at one end of the moving plate 4, and both sides of the outer wall of one end of the moving plate 4 are movably connected with the limiting groove through limiting wheels;

[0022] A gasket 16 is installed on the outer wall above the oil plug 13, and a top plate 17 is connected to the top end of the oil plug 13;

[0023] Both sides of the bottom end of the top plate 17 are connected with dampers 11, and first return springs 15 are installed on the outer walls of the dampers 11;

[0024] Specifically, as Figure 2 and Figure 3As shown, when using this structure, the rotating rod 9 rotates to drive the ramming rod 12 to rotate simultaneously. After the ramming rod 12 rotates below the oil plug 13, the ramming rod 12 presses the oil plug 13 upward, and at the same time, the gasket 16 moves upward, so that the lubricating oil in the oil box 10 flows downward through the gap between the oil plug 13 and the oil hole 14. The lubricating oil falls downward on the gear 3, and through the meshing of the gear 3 and the rack 5, the lubricating oil contacts the rack 5, realizing the self-lubrication function.

[0025] Embodiment 2: The inner wall below the locking sleeve 18 is provided with internal threads, and the outer wall above the rotating rod 9 is provided with external threads, forming a threaded connection structure between the locking sleeve 18 and the rotating rod 9;

[0026] The outer walls on both sides of the rotating rod 9 are both movably connected with moving rods 19, and one end of each moving rod 19 is connected with a lock block 20. The outer wall of the steering wheel 8 is provided with lock grooves 21 that cooperate with the lock blocks 20;

[0027] The outer walls of the other ends of the moving rods 19 are all installed with second return springs 22, and one end of each second return spring 22 is fixedly connected to the outer wall of the rotating rod 9;

[0028] Specifically, as Figure 2 and Figure 4 shown, when using this structure, by positioning the steering wheel 8 in the rotating rod 9 and rotating the locking sleeve 18, with threaded cooperation, the locking sleeve 18 moves upward so that the second return spring 22 is compressed inside, and at the same time, the moving rod 19 drives the lock block 20 to engage in the lock groove 21, facilitating the quick connection and installation of the transmission structure and the steering wheel 8. By rotating the locking sleeve 18 downward in the reverse direction, the second return spring 22 disengages from the inside of the locking sleeve 18, and the second return spring 22 resets to make the lock block 20 move away from the lock groove 21, facilitating the quick disassembly of the transmission structure and the steering wheel 8 and facilitating the quick disassembly and assembly work.

[0029] Working principle: When using this device, first rotate the steering wheel 8 to drive the rotating rod 9 to rotate the gear 3. Through the meshing of the gear 3 and the rack 5, the rack 5 drives the moving plate 4 to move to one side. By the movement of the moving plate 4, the moving rod 2 on one side pushes the steering member 1 to rotate an angle, thereby rotating the moving wheel 6 by an angle. By the movement of the moving plate 4, the moving rod 2 on the other side pulls the steering member 1 to rotate an angle, causing the moving wheel 6 to rotate by an angle, and the moving wheels 6 on both sides rotate in the same direction, realizing the steering work of the vehicle;

[0030] Implementation steps of the first innovation point:

[0031] The rotation of the rotating rod 9 drives the ram rod 12 to rotate simultaneously. After the ram rod 12 rotates below the oil plug 13, the ram rod 12 presses the oil plug 13 upward, and at the same time, the gasket 16 moves upward, so that the lubricating oil in the oil box 10 flows downward through the gap between the oil plug 13 and the oil hole 14. The lubricating oil falls downward onto the gear 3, and through the meshing of the gear 3 and the rack 5, the lubricating oil contacts the rack 5, making the meshing smoother.

[0032] Implementation steps of the second innovation point:

[0033] First step: By positioning the steering wheel 8 inside the rotating rod 9 and rotating the locking sleeve 18, with a threaded fit, the locking sleeve 18 moves upward, squeezing the second return spring 22 inside. At the same time, the moving rod 19 drives the lock block 20 to snap into the lock groove 21, facilitating the quick connection and installation of the transmission structure and the steering wheel 8.

[0034] Second step: By rotating the locking sleeve 18 downward in the reverse direction, the second return spring 22 disengages from inside the locking sleeve 18, and the second return spring 22 resets, causing the lock block 20 to move away from the lock groove 21, facilitating the quick disassembly of the transmission structure and the steering wheel 8.

[0035] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
