It usually includes components such as the wheel hub, bearings, seals, and brake discs (in some designs).

[0003] In order to maintain and extend the service life of the existing automobile wheel hub unit, lubricating oil is injected into the interior. However, due to the shape of the automobile wheel hub unit, the automobile wheel hub unit needs to be disassembled and then the lubricating oil is added each time. Therefore, the whole process is very cumbersome, making it inconvenient to quickly lubricate the interior of the automobile wheel hub unit. Utility Model Content

[0004] The purpose of the utility model is to provide an automobile wheel hub unit with end face teeth riveted, so as to solve the problem in the above background art that the automobile wheel hub units currently used are inconvenient to add lubricating oil to the interior.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 3 The utility model provides a technical solution: an end-face-tooth-riveted automobile wheel hub unit, comprising: a main shaft 1 and a spline groove 8; an automobile wheel hub unit body 2 is sleeved on the outer side of the main shaft 1; an inner ring 3 is arranged inside the automobile wheel hub unit body 2; an outer ring 4 is arranged on the outer side of the inner ring 3; a retainer 5 is arranged between the grooves of the inner ring 3 and the outer ring 4; a steel ball 6 is installed on one side of the retainer 5; a wheel hub flange 7 is connected to one side of the automobile wheel hub unit body 2; and a spline groove 8 is provided on the left end face of the outer ring 4;

[0025] An oil storage tank 9 is installed on the outside of the outer ring 4. The bottom of the oil storage tank 9 passes through the outer ring 4 and is connected to an oil outlet pipe 10. A piston 11 is installed inside the oil outlet pipe 10. Oil outlet holes 12 are opened on both sides of the oil outlet pipe 10. A connecting rod 13 passing through the oil storage tank 9 is installed on the top of the piston 11. A protrusion 14 is installed on one side of the connecting rod 13. A wedge block 15 is provided on one side of the protrusion 14. A fixed block 16 is installed on one side of the wedge block 15. A movable spring 17 is connected between the wedge block 15 and the groove of the fixed block 16. The fixed block 16 is installed on the top of the oil storage tank 9. The wedge block 15 forms a telescopic structure between the movable spring 17 and the groove of the fixed block 16.

[0026] In a specific implementation, when the steel balls 6 need to be lubricated, the connecting rod 13 can be pulled toward the outside of the oil tank 9. The movement of the connecting rod 13 will drive the piston 11 in the oil outlet pipe 10 to move upward, so that the position of the piston 11 is higher than the height of the oil outlet hole 12 on the side of the oil outlet pipe 10. Without the obstruction of the piston 11, the lubricating oil inside the oil tank 9 will flow through the oil outlet hole 12 and the oil outlet pipe 10 to the steel balls in the grooves of the inner ring 3 and the outer ring 4, thereby lubricating the steel balls.

[0027] At the same time, the upward movement of the connecting rod 13 causes the protrusion 14 on one side to squeeze the wedge block 15, thereby squeezing the wedge block 15 into the groove of the fixing block 16. When the height of the protrusion 14 exceeds the wedge block 15, the wedge block 15 will return to its original position, thereby fixing the position of the connecting rod 13 and facilitating the rapid lubrication of the inner ring 3 and the outer ring 4.

[0028] On the contrary, it is only necessary to pull the wedge block 15 toward the inside of the fixed block 16 again, without the wedge block 15 limiting the protrusion 14 on one side of the connecting rod 13, and then the piston 11 can be pushed downward through the connecting rod 13, so that the piston 11 moves to the bottom of the oil outlet hole 12. At this time, the oil outlet pipe 10 can be sealed by the piston 11.

[0029] See Figure 2 and Figure 4 It can be seen that when in use, the connecting rod 13 can be pulled according to the use requirements, so that the connecting rod 13 drives the piston 11 to move upward. The upward movement of the piston 11 does not block the oil outlet hole 12, and then the lubricating oil inside the oil storage tank 9 will flow into the inner ring 3 and the outer ring 4 through the oil outlet hole 12 and the oil outlet pipe 10, thereby facilitating the lubrication of the automobile hub unit.

[0030] One end of the outer ring 4 is connected to a dust cover 18, one end of the dust cover 18 is installed with an insert block 19, one end of the insert block 19 is installed with a limit block 20, the outer side of the insert block 19 is sleeved with a mounting block 21, the outer side of the limit block 20 is sleeved with a movable block 22, the top of the movable block 22 is installed with a movable rod 23 passing through the mounting block 21, one end of the movable rod 23 is sleeved with a connecting block 24, one side of the connecting block 24 is connected to a telescopic block 25, the inside of the telescopic block 25 is installed with a telescopic spring 26, and the mounting block 21 is installed on the outside of the outer ring 4.

[0031] During specific implementation, when the dust cover 18 of the end face tooth riveted automobile hub unit needs to be installed on one side of the outer ring 4, it is only necessary to pull the telescopic block 25 upward so that the telescopic block 25 drives the connecting block 24 on one side to move upward. At this time, the connecting block 24 does not limit the movable rod 23, and then the movable rod 23 can be pushed to one side. When the movable rod 23 is pushed to one end of the mounting block 21, the internal groove of the mounting block 21 is larger, and the movable block 22 can be pulled into the groove of the mounting block 21 by the movable rod 23. Then, the plug-in block 19 on one side of the dust cover 18 is plugged into the mounting block 21;

[0032] When the insert block 19 is fully inserted into the groove of the mounting block 21, push the movable rod 23 downward so that the movable rod 23 pushes the movable block 22 out of the groove of the mounting block 21, and then push the movable rod 23 horizontally. At this time, the movable block 22 will be sleeved onto the outside of the limit block 20. At this time, release the telescopic block 25. Under the reset action of the telescopic spring 26, the connecting block 24 will move downward and sleeve onto the outside of the movable rod 23, so that the position of the movable rod 23 can be limited. The insert block 19 can be fixed in the mounting block 21 through the limit block 20 and the movable block 22, so that the dust cover 18 can be fixed on one side of the outer ring 4. The dust cover 18 can increase the dustproof effect of the entire automobile hub unit, making it difficult for dust to enter the automobile hub unit.

[0033] See Figure 2 、 Figure 5 and Figure 6 It can be seen that when in use, the plug block 19 at one end of the dust cover 18 can be inserted into the mounting block 21 according to the use requirements, and then the limit block 20 at one end of the plug block 19 can be fixed by the movable rod 23 and the movable block 22, so that the plug block 19 cannot move out of the groove of the mounting block 21, and then the dust cover 18 can be stably installed on one side of the automobile hub unit, thereby playing a dust-proof role for the automobile hub unit.

[0034] To sum up: when the end face tooth riveted automobile wheel hub unit is in use, the main shaft 1 can be inserted into the inner ring 3 of the automobile wheel hub unit body 2, and the main shaft 1 and the automobile wheel hub unit body 2 are connected through the spline groove 8, and then the automobile wheel hub unit body 2 and the wheel hub are connected through the hub flange 7. When the main shaft 1 rotates, it will drive the wheel hub to rotate through the spline groove 8 and the automobile wheel hub unit body 2. This is the usage feature of the end face tooth riveted automobile wheel hub unit. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
