DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] A car steering knuckle with a self-lubricating mechanism comprises a steering knuckle 1 and a self-lubricating mechanism 2 mounted on the steering knuckle 1. The steering knuckle 1 is provided with a central mounting hole 1-1 and a lubricating through hole 1-2. The central mounting hole 1-1 is used for mounting a rotating shaft of a vehicle. The lubricating through hole 1-2 is connected to the central mounting hole 1-1. The self-lubricating mechanism 2 is connected to the lubricating through hole 1-2. To facilitate the self-lubricating mechanism 2 to lubricate the neutral mounting hole 1-1, a pushing piece 3 is provided in the self-lubricating mechanism 2. The grease in the self-lubricating mechanism 2 is transported to the central mounting hole 1-1 through the pushing piece 3, thereby facilitating the grease to lubricate the central mounting hole 1-1.

[0025] The lubrication through hole 1-2 and the connection part (the part used to connect the tie rod, swing arm and other parts) on the steering knuckle are staggered to prevent the through hole from affecting the strength of the connection part, thereby ensuring that the steering knuckle has good strength.

[0026] The axis of the lubricating through hole 1-2 is inclined relative to the radial line of the central mounting hole 1-1, thereby increasing the opening area of ​​the lubricating through hole 1-2 in the central mounting hole 1-1, so that the lubricating through hole 1-2 can better lubricate the components in the central mounting hole 1-1.

[0027] There is only one lubrication hole 1-2 on the steering knuckle 1. Since the circumference of the lubrication hole 1-2 is inclined relative to the diameter of the center mounting hole 1-1, when the component in the center mounting hole 1-1 rotates toward the inclined direction of the axis of the lubrication hole 1-2, the lubrication hole 1-2 can better lubricate the component. When the component in the center mounting hole 1-1 rotates away from the inclined direction of the axis of the lubrication hole 1-2, the lubrication effect of the lubrication hole 1-2 on the component is poor. In order to ensure that the component has a good lubrication effect in both forward and reverse rotations in the lubrication hole 1-2, two lubrication holes 1-2 are provided on the steering knuckle 1, and the axes of the two lubrication holes 1-2 are arranged vertically.

[0028] A lubrication groove 1-3 is provided in the center mounting hole 1-1, and the lubrication groove 1-3 is connected to the lubrication through hole 1-2. The lubrication groove 1-3 is annular. Through the setting of the lubrication groove 1-3, the lubricating oil / grease can better contact the internal parts of the center mounting hole 1-1, thereby improving the lubrication effect.

[0029] An oil storage chamber 2 - 1 is provided in the self-lubricating mechanism 2 , and a push piece 3 is slidably installed in the oil storage chamber 2 - 1 , and the grease in the oil storage chamber 2 - 1 is transported to the lubricating through hole 1 - 2 through the push piece 3 .

[0030] The self-lubricating mechanism 2 includes a fixed seat 2-2 and a disassembly seat 2-3 installed on the fixed seat 2-2. A first oil storage tank 2-4 is provided in the fixed seat 2-2, and a second oil storage tank 2-5 is provided in the disassembly seat 2-3. The pushing member 3 is slidably installed in the second oil storage tank 2-5. The first oil storage tank 2-4 and the second oil storage tank 2-5 are connected to form an oil storage chamber 2-1. The disassembly seat 2-3 is disassembled to replenish the lubricating oil / grease to the disassembly seat 2-3, thereby replenishing the oil in the oil storage chamber.

[0031] The push piece 3 includes a guide rod 3-1 and a piston 3-2 installed at the end of the guide rod 3-1. The piston 3-2 is slidably installed in the disassembly seat 2-3. A push spring 4 is provided between the piston 3-2 and the inner wall of the second oil storage tank 2-5. The piston 3-2 is driven to move by the push spring 4, so that the oil in the oil storage chamber 2-1 is transported to the lubricating through hole 1-2. The disassembly seat 2-3 is provided with a guide through hole 2-6, and the guide rod 3-1 is movably installed in the guide through hole 2-6. The push piece 3 in this embodiment is driven by a spring, which greatly simplifies the structure of the self-lubricating mechanism 2 and reduces the production cost of the steering knuckle.

[0032] A mounting platform 1 - 4 is provided on the side wall of the steering knuckle 1 . The mounting platform 1 - 4 is staggered with respect to a connecting portion on the steering knuckle. The self-lubricating mechanism 2 is fixedly mounted on the mounting platform 1 - 4 via a sealing gasket 5 .
