Description

Technical Field

[0001] This utility model belongs to the field of steering knuckle technology, and relates to a steering knuckle, particularly a steering knuckle with lubrication function. Background Technology

[0002] As an essential component, the steering knuckle plays a crucial role in the steering system. The existing steering knuckle is connected to the vehicle's steering knuckle arm via a pin and to the vehicle's steering wheel via a journal. The steering transmission mechanism is connected to the steering knuckle, and the rotation of the steering transmission mechanism will cause the steering knuckle to rotate at an angle relative to the steering knuckle arm. The rotation of the steering knuckle will cause the vehicle's tires to rotate, thereby realizing the steering of the vehicle.

[0003] After a period of use, existing steering knuckles require lubrication of the steering components by manually spraying lubricating oil, but this operation is time-consuming, labor-intensive, and quite troublesome. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a steering knuckle with a lubrication function.

[0005] The objective of this utility model can be achieved through the following technical solution: A steering knuckle with lubrication function, comprising a steering knuckle body and a steering knuckle fork, characterized in that a shaft is provided on the steering knuckle body and the steering knuckle fork, and the steering knuckle body and the steering knuckle fork are movable on the steering knuckle fork; a flange and a positioning rod are provided at the lower end of the shaft; a slot is provided at the upper end of the shaft; a sealing cover assembly for sealing and movable up and down is provided inside the shaft and relative to the slot; the sealing cover assembly includes a first sealing element, a second sealing element, a baffle, a connecting rod and a return spring; a fixing part is provided in the slot, and the fixing part divides the internal space of the slot into an oil storage chamber and an oil inlet chamber; a plurality of oil passage holes for oil passage are provided on the fixing part; the connecting rod passes through the fixing part; the baffle is provided at the lower end of the connecting rod; and an oil passage channel communicating with the oil inlet chamber is provided inside the shaft.

[0006] In the aforementioned steering knuckle with lubrication function, the second seal is located at the upper end of the fixed part, and several oil passages are sealed by controlling the up and down movement of the connecting rod. The first seal is located at the opening of the shaft groove, and the internal oil storage chamber is sealed by controlling the up and down movement of the connecting rod.

[0007] In the aforementioned steering knuckle with lubrication function, one end of the return spring is connected to the baffle, and the other end of the return spring is connected to the lower end of the fixing part.

[0008] Compared with existing technologies, this steering knuckle with lubrication function has an oil inlet chamber and an oil reservoir inside the shaft, as well as an oil passage, which can lubricate the connection between the steering knuckle body and the steering knuckle fork, thereby improving the service life of the steering knuckle.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, this lubrication-enabled steering knuckle includes a steering knuckle body 1 and a steering knuckle fork 2. A shaft 3 is provided on both the steering knuckle body 1 and the steering knuckle fork 2, and the steering knuckle body 1 and steering knuckle fork 2 are movable. A flange and a positioning rod are provided at the lower end of the shaft 3, and a slot 4 is provided at the upper end of the shaft 3. A sealing cover assembly 5, which is movable up and down and is used for sealing, is provided inside the shaft 3 and relative to the slot 4. The sealing cover assembly 5 includes a first seal 6, a second seal 7, a baffle 8, a connecting rod 9, and a return spring 10. A fixing part 11 is provided inside the slot 4, and the fixing part 11 divides the internal space of the slot 4 into an oil storage chamber and an oil inlet chamber. Several oil passage holes 12 for oil passage are provided on the fixing part 11. The connecting rod 9 passes through the fixing part 11, and the baffle 8 is provided at the lower end of the connecting rod 9. An oil passage 13 communicating with the oil inlet chamber is provided inside the shaft 3.

[0014] To elaborate further, when it is necessary to add lubricating oil to the inside, pull the connecting rod 9 to move the seal 6 upward, adding lubricating oil into the oil storage space. At the same time, the seal 7 moves upward, compressing the return spring 10, and some lubricating oil enters the oil inlet space and enters the space between the shaft 3 and the steering knuckle fork 2 through the oil passage 13. Release the connecting rod 9, and the return spring 10 rebounds, resealing the oil passage 12 and the slot 4 to prevent dust from entering the shaft 3.

[0015] To elaborate further, the second seal 7 is located at the upper end of the fixed part 11, and the sealing of several oil passage holes 12 is controlled by the up and down movement of the connecting rod 9. The first seal 6 is located at the opening of the groove 4 of the shaft 3, and the sealing of the internal oil storage cavity is controlled by the up and down movement of the connecting rod 9.

[0016] To elaborate further, one end of the return spring 10 is connected to the baffle 8, and the other end of the return spring 10 is connected to the lower end of the fixing part 11.

[0017] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0018] Although this document frequently uses terms such as steering knuckle body 1, steering knuckle fork 2, shaft 3, slot 4, sealing cover assembly 5, seal 1 6, seal 2 7, baffle 8, connecting rod, return spring 10, fixing part 11, oil passage hole 12, and oil passage 13, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
