Improved structure of vehicle balance bar bracket joint

The present invention relates to a balance bar bracket joint, and in particular to an improved structure of a vehicle balance bar bracket joint.

Cars are an indispensable and important way of moving in modern people's lives. Whether it is commuting, transporting goods or going out to play, it is one of the preferred mobile means. The more people choose a car, the more time it takes for the person to be in the car. At this time, the feeling of riding, or the safety of the items to be transported, the importance of the stability of the vehicle is increasing.

Vehicles use suspension systems to increase stability when seeking greater stability. Suspension system refers to the buffering ability between the chassis and the wheel of the vehicle through the balance bar, connecting rod, pneumatic valve, spring, etc., which absorbs the vibration caused by the unevenness of the wheel, so that the vibration transmitted to the chassis is minimized. Structure. When the vibration transmitted to the chassis is reduced, the sway of the person or thing in the vehicle is reduced, and the effect of improving the riding feeling is achieved.

In the various components of the suspension system, including anti-roll bars, tripods, shock absorbers, etc., it is necessary to connect components to stabilize the structure, enhance the stability effect, and maintain stability.

Reduce the effectiveness of manufacturing time.

Based on the above purposes, the present invention provides an improved structure of a vehicle balance bar bracket joint, which comprises a ball sleeve, a spherical shell, a ball screw, a balance bar bracket, and a plurality of fixed columns. The ball sleeve constitutes an accommodation space and has a pair of grooves to form a claw type structure. The spherical shell is sleeved on the outer side of the spherical sleeve, and the bottom of the spherical shell has a plurality of fixing holes penetrating the spherical shell. The ball screw system has a spherical portion rotatably accommodated in the accommodating space of the ball sleeve. The balance bar bracket is attached to the side of the spherical shell. The plurality of fixed columns have a fixed end and a welded end, and the diameter of the fixed end is larger than the diameter of the fixed hole, and the welded end of the plurality of fixed columns abuts the ball sleeve through the plurality of fixing holes, and is ultrasonically welded to the bottom of the sleeve .

Preferably, the contact surface of the ball sleeve and the spherical shell has a corresponding snap structure to increase the pulling force of the spherical shell to the spherical sleeve.

Preferably, the accommodating space of the ball sleeve further comprises an oil storage tank for storing lubricating oil to reduce friction.

Preferably, the ball sleeve is made of plastic steel or nylon.

Preferably, the number of fixing holes is 4 to 6.

Preferably, the spherical shell is made of iron.

Preferably, the width of the groove of the sleeve is 1.9 to 2 mm.

In order to understand the technical features, contents and advantages of the creation and the effects that can be achieved, the present invention will be described in conjunction with the drawings and will be described in detail in the following examples, and the drawings used therein only have the subject matter. For the purpose of indicating and supporting the manual, it is not necessarily the true proportion and precise configuration after the implementation of the original creation. Therefore, the scope and configuration relationship of the attached drawings should not be interpreted or limited. Narration.

The embodiment of the improved structure of the vehicle balance bar bracket joint according to the present invention will be described below with reference to the related drawings. For ease of understanding, the same components in the following embodiments are denoted by the same reference numerals.
