DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In the description of the embodiments of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the embodiments of the present invention.

[0021] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0022] See also Figure 1-5 As shown, the utility model embodiment is a lightweight automobile steering knuckle, comprising a steering knuckle body 1, a mounting ear 2 is fixedly mounted on one side of the steering knuckle body 1, an oil filling port 21 is provided at the upper end of the mounting ear 2, an oil storage chamber 22 is provided at the lower end of the oil filling port 21, an oil delivery groove 23 is penetrated and connected to the bottom of the oil storage chamber 22, and oil delivery grooves 23 are provided inside the lower end of the mounting ear 2, a flow port 203 is penetrated and opened on one side of the two oil delivery grooves 23, a flow channel 24 is fixedly connected to one side of the lower end of the oil delivery groove 23, a bearing 51 is fixedly connected to the inner surface of the oil delivery groove 23, and a ball 5 is provided on the inner surface of the bearing 51.

[0023] A connecting plate 3 is fixedly connected to the middle of the inner surface of the oil filling port 21, and a plurality of telescopic rods 32 distributed in a circle array are fixedly connected to the lower surface of the connecting plate 3, and a pushing block 42 is fixedly connected to the lower end of the plurality of telescopic rods 32, and a spring 31 is fixedly connected between the top of the pushing block 42 and the connecting plate 3, and a rubber ring 43 is fixedly connected to the outer surface of the pushing block 42, and a push rod 4 is fixedly connected to the top of the pushing block 42.

[0024] The inner surface of the oil storage chamber 22 is arranged in an inclined shape. When the lubricating oil penetrates into the inner wall of the oil storage chamber 22 , the inclined shape will cause the lubricating oil to flow to the outer surface of the ball 5 .

[0025] The outer surface of the upper end of the push rod 4 is provided with a plurality of oil filling grooves 41 arranged in an arc shape, and a certain amount of lubricating oil can be carried into the oil storage cavity 22 through the oil filling grooves 41.

[0026] The top surface of the push block 42 is arranged in an arc shape, and when the lubricating oil falls onto the push block 42, the lubricating oil can slide down faster.

[0027] The outer diameter of the ball 5 matches the inner diameter of the flow opening 203 , and the flow opening 203 allows the ball 5 to contact the connecting piece.

[0028] When the embodiment of the utility model is used, the connecting piece is first inserted into the through hole of the mounting ear 2. When the gap between the mounting ear 2 and the connecting piece needs to be lubricated with lubricating oil, the lubricating oil is injected into the oil storage chamber 21. When the push rod 4 is pushed downward, the lubricating oil will flow into the oil filling groove 41. When the oil filling groove 41 moves to the lower end of the connecting plate 3, the push rod 4 will drive the pushing block 42 to slide downward. During this process, the pushing block 42 will stretch the spring 31. The arc shape inside the oil filling groove 41 allows the lubricating oil to slide to the outer surface of the ball 5. When the connecting piece and the mounting ear 2 rotate, the ball 5 will be driven to rotate through the bearing 51, so that the oil delivery groove 23 can continue to contact different outer surfaces of the ball 5, and thus the gap between the connecting piece and the mounting ear 2 can be continuously supplied with oil. When the push rod 4 is released, the rubber ring 43 can be driven to slide upward through the pushing block 42 through the reset effect of the spring 31, so that the oil filling port 21 can be in a closed state.

[0029] The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
