Abstract

This application relates to an integrated molded automotive stabilizer bar, belonging to the field of automotive parts technology. It includes a crossbar and connecting rods. Two connecting rods are provided, each located at one end of the crossbar, forming an integrated structure. Each connecting rod has a mounting sleeve b on one side, and a ball seat is fixedly connected to the end of the mounting sleeve b furthest from the connecting rod.

Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an integrated molded automotive stabilizer bar. Background Technology

[0002] In a car's suspension system, the stabilizer bar is a key component for suppressing vehicle roll. Its core function is to generate anti-roll drag to prevent the bar from twisting when the left and right wheels of the vehicle experience a difference in horizontal height due to road undulations or cornering, thereby stabilizing the vehicle's posture. When the left and right suspensions move in sync, the stabilizer bar is in a non-functional state.

[0003] A typical automotive stabilizer bar structure includes a bar body and ball joint assemblies connecting both ends of the bar body. The ball joint assemblies are movably connected to the suspension components via ball seats to achieve multi-angle transmission during steering. However, during frequent steering operations, continuous friction occurs between the ball joints and ball seats, which can easily lead to wear and tear on the components over long-term use.

[0004] Currently, the lubrication method of stabilizer bar ball joint assembly has obvious limitations. It cannot achieve continuous lubrication during vehicle operation. As the usage time increases, the lubrication of the ball joint assembly gradually becomes insufficient. This not only produces obvious noise when turning, affecting the driving experience, but also aggravates the mechanical wear of the components, causing the ball joint assembly to fail prematurely and severely shortening the overall service life of the stabilizer bar. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of this application is to provide an integrated molded automotive stabilizer bar.

[0006] The technical solution of this application is as follows: an integrated automotive balance bar includes a crossbar and connecting rods. Two connecting rods are provided, each located at one end of the crossbar and forming an integrated structure. Each connecting rod has a mounting sleeve b on one side. A ball seat is fixedly connected to the end of each mounting sleeve b away from the connecting rod. A pressure chamber is fixedly mounted on the top of the ball seat. A piston plate is slidably connected inside the pressure chamber. An outlet pipe and an inlet pipe are fixedly connected to one side of the pressure chamber. A storage tank is fixedly connected to the top of each mounting sleeve b. The end of the inlet pipe away from the pressure chamber extends into the storage tank. A flow channel is formed inside the ball seat, and the end of the outlet pipe away from the pressure chamber extends into the flow channel.

[0007] In a preferred embodiment, mounting sleeve a is provided on the side of mounting sleeve b away from the ball seat. A threaded post is threadedly connected between mounting sleeve a and mounting sleeve b. A locking nut is threadedly connected to the outer side of the threaded post. Iron parts are fitted on the outer periphery of the threaded post and on the side of the locking nut.

[0008] In a preferred embodiment, a protective sleeve is provided around the outer periphery of the locking nut, and a magnetic piece for attracting iron parts is embedded in one side of the protective sleeve, with the iron parts abutting between the mounting sleeve a and the locking nut.

[0009] In a preferred embodiment, the ball seat has a swaying groove inside, a ball head is installed inside the swaying groove, and a plurality of liquid inlet holes are provided between the liquid flow channel and the swaying groove.

[0010] In a preferred embodiment, an electric telescopic rod is fixedly installed on the outside of the pressure chamber, and the piston rod of the electric telescopic rod extends into the interior of the pressure chamber and is fixedly connected to the piston plate.

[0011] In a preferred embodiment, the connecting rod is engaged between mounting sleeve a and mounting sleeve b, and the top of the storage tank is fixedly connected to a liquid inlet.

[0012] In a preferred embodiment, both the outlet pipe and the inlet pipe are fixedly equipped with one-way valves.

[0013] In a preferred embodiment, a clamp is installed on the outer side of the connecting rod and on the side of the mounting sleeve a.

[0014] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0015] 1. In this application, when the vehicle is in motion, the retraction of the piston rod of the electric telescopic rod can drive the piston plate to draw the lubricant in the storage tank into the pressurization tank through the inlet pipe. Then, through the extension of the piston rod of the electric telescopic rod, the lubricant can be delivered to the friction surface between the ball head and the swaying groove through the outlet pipe, so as to achieve timely lubrication titration. This structure reduces the situation where the existing lubrication method cannot supply oil in time, effectively reduces the friction and wear between the ball head and the ball seat, eliminates steering noise, and significantly extends the service life of the ball head assembly.

[0016] 2. In this application, the setting of threaded post and locking nut can provide basic fastening force, while the iron part abutting between the mounting sleeve a and the locking nut can prevent the thread from loosening. Furthermore, the magnetic sheet of the protective sleeve attracts the iron part to further prevent the component from shifting. At the same time, the protective sleeve can isolate dust and moisture, reduce the risk of thread corrosion, and greatly improve the long-term stability of the connection between the connecting rod and the ball seat assembly.

Furthermore, the magnetic plate 5 of the protective sleeve 4 attracts the iron parts 15, further preventing... To prevent component displacement, the protective sleeve 4 isolates dust and moisture, reducing the risk of thread corrosion and significantly improving the long-term stability of the connection between the connecting rod 2 and the ball seat assembly. The outer periphery of the locking nut 14 is fitted with a protective sleeve 4, and a magnetic piece 5 that attracts the iron part 15 is embedded in one side of the protective sleeve 4.

The one-way valve 20 in the outlet pipe 10... This structure prevents the lubricating oil in the flow tank 16 from flowing back into the pressure tank 13, thus enabling timely lubrication titration. This structure reduces the situation where existing lubrication methods cannot supply oil in time, effectively reducing friction and wear between the ball head 12 and the ball seat. The threaded connection between the threaded column 7 and the locking nut 14 provides basic fastening force, while the iron part 15 abuts against the mounting sleeve a3 and the locking nut 14 to prevent the threads from loosening.
