[0015] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-4 A drive axle half-shaft connecting frame structure for easy installation includes a connecting frame body 1. A first connector 2 is provided on one side of the connecting frame body 1, and a positioning bolt 9 is provided on one side of the first connector 2, with the positioning bolt 9 threadedly connected to one side of the first connector 2. An angle adjuster 6 is provided on one side of the connecting frame body 1, and the angle adjuster 6 is movably connected to one side of the connecting frame body 1. An elastic buffer pad 7 is provided on one side of the angle adjuster 6, and the interior of the elastic buffer pad 7 is positioned connected to the angle adjuster 6. A mounting groove 8 is provided on one side of the angle adjuster 6, and the mounting groove 8 is welded to one side of the angle adjuster 6. A fastening bolt 10 is provided on one side of the angle adjuster 6, and the fastening bolt 10 is threadedly connected to one side of the angle adjuster 6. An arc groove 11 is installed on one side of the connecting frame body 1, and the side of the arc groove 11 is rounded. A second connector 3, a third connector 4, and a fourth connector 5 are provided on one side of the connecting frame body 1. A positioning bolt 9 is provided on one side of the first connector 2. An angle adjuster 6 is provided inside the first connector 2. A fastening bolt 10 is provided on one side of the angle adjuster 6. An elastic buffer pad 7 is provided on one side of the angle adjuster 6. The addition of the elastic buffer pad 7 absorbs vibration and reduces transmission noise. The first connector 2, the second connector 3, the third connector 4, and the fourth connector 5 are respectively provided on both sides of the connecting frame body 1, and all of them are threaded to both sides of the connecting frame body 1. This allows the angle adjuster 6 to compensate and correct for minor manufacturing or installation deviations between the drive axle and the half shaft, ensuring the reliability of the connection. At the same time, it allows the half shaft to maintain a certain dynamic angle compensation during vehicle movement, extending the service life of the half shaft and the connector. Meanwhile, the elastic buffer pad 7 can effectively isolate and absorb high-frequency and low-frequency vibrations from the half shaft, transmission system, or road surface, reducing direct impact and friction between rigid connecting parts, thereby significantly reducing the transmission of transmission noise to the vehicle body and improving the quietness of the device. Specific Implementation Example 2: Reference Figure 1-4Based on the basic structure in Specific Embodiment 1, a ratchet locking mechanism is adopted at the threaded connection of the fastening bolt 10.

The connecting frame body 1 has a first connector 2, a second connector 3, a third connector 4, and a fourth connector 5 on both sides, all threaded to the sides of the connecting frame body 1. This allows the angle adjuster 6 to compensate and correct for minor manufacturing or installation deviations between the drive axle and the half-shaft, ensuring connection reliability. It also allows the half-shaft to maintain a certain dynamic angle compensation during vehicle movement, extending the service life of the half-shaft and connectors. Simultaneously, the elastic buffer pad 7 effectively isolates and absorbs high-frequency and low-frequency vibrations from the half-shaft, transmission system, or road surface, reducing direct impact and friction between rigid connecting parts, thereby significantly reducing the transmission of transmission noise to the vehicle body and improving the device's quietness.
