Description

Technical Field

[0001] The utility model belongs to the technical field of automotive steering knuckles, and relates to a steering knuckle, in particular to a novel steering knuckle. Background Art

[0002] The function of the steering knuckle is to transmit and bear the load at the front part of the vehicle, support and drive the front wheels to rotate around the kingpin to steer the vehicle. When the vehicle is running, it bears variable impact loads. Therefore, it is required to have high strength.

[0003] The automotive bearing is long-term on the inner wall of the installation groove, and the steering knuckle rotates for a long time, which causes friction between the automotive bearing and the inner wall of the installation groove of the steering knuckle, and then increases the wear of the steering knuckle and the automotive bearing, shortening their service life. The existing steering knuckle can only steer the vehicle tire and is not convenient for lubricating between the steering knuckle and the automotive bearing. Summary of the Invention

[0004] The purpose of the utility model is to provide a novel steering knuckle with automatic lubrication for the above problems existing in the prior art.

[0005] The purpose of the utility model can be realized by the following technical solutions: A novel steering knuckle, including a steering knuckle body and a steering shaft. Upper and lower fixing ears are respectively arranged at the upper and lower ends of the steering knuckle body. It is characterized in that through holes are opened on both the upper fixing ear and the lower fixing ear, bearings are arranged on the through holes, oil storage grooves are opened on both the upper fixing ear and the lower fixing ear, several oil outlet holes are opened on the inner wall of the through hole, and balls are arranged on several oil outlet holes.

[0006] In the above novel steering knuckle, oil injection pipes communicating with the oil storage grooves are arranged on both the upper fixing ear and the lower fixing ear, and plugs are arranged on the oil injection pipes.

[0007] In the above novel steering knuckle, the oil outlet holes communicate with the oil storage grooves.

[0008] Compared with the prior art, the oil storage grooves, oil outlet holes and balls arranged in the utility model can change the sliding friction between the bearing and the surface of the through hole into rolling friction during rotation to reduce the friction force. When the balls are moving, they can bring out the oil from the oil storage layer to form an automatic lubrication for the bearing surface and the balls. Brief Description of the Drawings

[0010] Figure 2 It is a sectional view structural schematic diagram of the utility model.

[0011] Figure 3 It is a schematic diagram of the partial enlarged structure at location A of the present utility model.

[0012] In the figure, 1 is the knuckle main body; 2 is the steering shaft; 3 is the upper fixing ear; 4 is the lower fixing ear; 5 is the through hole; 6 is the bearing; 7 is the oil storage groove; 8 is the oil outlet hole; 9 is the ball; 10 is the oil injection pipeline; 11 is the plug. Specific embodiments

[0013] The following are specific embodiments of the present utility model and in combination with the attached drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0014] As Figure 1 、 Figure 2 、 Figure 3 shown, the new type of knuckle includes a knuckle main body 1 and a steering shaft 2. Upper fixing ears 3 and lower fixing ears 4 are respectively arranged at the upper and lower ends of the knuckle main body 1. Through holes 5 are opened on both the upper fixing ear 3 and the lower fixing ear 4. Bearings 6 are arranged on the through holes 5. Oil storage grooves 7 are opened on both the upper fixing ear 3 and the lower fixing ear 4. A plurality of oil outlet holes 8 are opened on the inner wall of the through hole 5. Balls 9 are arranged on each of the plurality of oil outlet holes 8. The arranged oil storage grooves 7, oil outlet holes 8 and balls 9 can change the sliding friction between the bearing 6 and the surface of the through hole 5 into rolling friction during rotation to reduce the frictional force. When the balls 9 are moving, they can bring out the oil liquid from the oil storage layer to form an automatic lubrication for the surface of the bearing 6 and the balls 9.

[0015] Further elaborating, oil injection pipelines 10 communicating with the oil storage grooves 7 are arranged on both the upper fixing ear 3 and the lower fixing ear 4. Plugs 11 are arranged on the oil injection pipelines 10, and the oil storage grooves 7 can be refilled with oil after the oil liquid decreases.

[0016] Further elaborating, the oil outlet holes 8 communicate with the oil storage grooves 7.

[0017] The specific embodiments described herein are only illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0018] Although this text uses more terms such as 1. knuckle body 1; 2. steering shaft 2; 3. upper fixed ear 3; 4. lower fixed ear 4; 5. through hole 5; 6. bearing 6; 7. oil storage tank 7; 8. oil outlet hole 8; 9. ball 9; 10. oil injection pipeline 10; 11. plug 11, etc., it does not exclude the possibility of using other terms. The use of these terms is only to more conveniently describe and explain the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
