Description
Technical Field
[0001] This utility model relates to the field of automotive steering technology, specifically a guide bushing lubrication mechanism for automotive steering systems. Background Technology
[0002] The automotive steering system, also known as the steering gear or steering transmission mechanism, is a core component that connects the driver's steering operations (such as turning the steering wheel) with the steering movements of the car wheels. Its core function is to amplify the relatively small force applied by the driver to the steering wheel and change the direction of force transmission, ultimately driving the steering wheels to deflect according to the driver's intention. This allows for precise control of the car's direction of travel, ensuring stable and controllable steering performance in various driving scenarios such as driving straight, turning, and changing lanes. It not only directly affects the car's handling precision, steering sensitivity, and driving stability but is also closely related to driving safety, serving as a core assembly that ensures the vehicle travels along the driver's intended trajectory.
[0003] Currently, automotive steering systems include I-beams and corresponding steering knuckle structures. In existing technology, workers install bushing structures inside the steering knuckle, align the kingpin hole of the steering knuckle with the kingpin hole of the I-beam, and then assemble the kingpin into the kingpin hole, so that the steering knuckle can rotate around the kingpin to achieve the steering function.
[0004] Traditional lubrication mechanisms have a fixed oil reservoir capacity, while steering gears of different displacements have significantly different lubricant requirements. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a guide bushing lubrication mechanism for automobile steering systems.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a lubrication mechanism for a guide bushing of an automobile steering gear, including a bushing, the bushing being provided with an adjustment mechanism, the adjustment mechanism including two handles, a screw head groove being opened above the handles, a threaded rod being fixedly connected below the handles, a limit ring being fixedly connected to the threaded rod near its upper outer wall, a threaded sleeve being threadedly connected to the outer wall of the threaded rod, a nut being threadedly connected to the upper outer wall of the threaded rod, and a semi-circular adjustment plate being fixedly connected below the threaded sleeve.
[0007] Preferably, the bushing includes two fixed sleeves, and inserts are fixedly connected to the left and right sides of the two fixed sleeves on the opposite side. An oil storage sleeve is fixedly connected to the inner wall of the fixed sleeve. Semi-circular grooves are opened on the upper part of the left and right sides of the inner wall of the oil storage sleeve. Several No. 1 oil outlet holes are opened on the lower part of the inner wall of the two semi-circular grooves on the side that is close to each other. A circular groove is opened in the middle of the upper part of the inner wall of the semi-circular groove. A cross-shaped circular hole is opened on the upper part of the inner wall of the circular groove.
[0008] Preferably, the inner wall of the oil storage sleeve is fixedly connected to a wear-resistant sleeve, and a second air outlet is opened at the position corresponding to the first oil outlet. The inner wall of the semi-circular groove is slidably connected to the outer wall of the semi-circular adjusting plate, the outer wall of the threaded sleeve is slidably connected to the inner wall of the circular groove, and the inner wall of the cross-shaped circular hole is rotatably connected to the threaded rod and the outer wall of the limiting ring.
[0009] Preferably, the inner wall of the wear-resistant sleeve is rotatably connected to a first spindle, the first spindle including a second spindle, the upper and lower sides of the second spindle are provided with sealing caps, and the upper and lower outer walls of the second spindle are rotatably connected to the inner walls of the two wear-resistant sleeves.
[0010] Preferably, the outer wall of the fixing sleeve has a first bushing, which includes two second bushings, and slots are provided on the left and right sides of the two second bushings that are far apart from each other.
[0011] Preferably, the inner wall of the slot is slidably connected to the outer wall of the insert, and the two opposite sides of the second bushings are fixedly connected to the opposite sides of the two sealing caps.
[0012] Preferably, a steering knuckle is fixedly connected to the rear of the two second bushings.
[0013] Preferably, an I-beam is fixedly connected to the front center of the second spindle.
[0014] The advantages of this utility model are: This invention allows the threaded rod and threaded sleeve to rotate by rotating the handle. The threaded sleeve slides against the circular groove and pushes the semi-circular adjusting plate. The semi-circular adjusting plate slides against the semi-circular groove to adjust the oil storage chamber capacity. Finally, the nut is rotated to fix it. A slidable semi-circular adjusting plate is set in the semi-circular groove of the middle oil storage sleeve. The position of the semi-circular adjusting plate is controlled by the threaded rod. The oil storage capacity can be accurately matched according to the displacement of the steering gear, adapting to steering gears of different displacements and avoiding the adaptation problem of using a large cavity for a small or small cavity for a large.
