[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-3 As shown, a sound insulation component for preventing wheel misalignment in automobiles includes a fixing layer 1, an upper sound insulation layer 2, and a lower sound insulation layer 3. The upper sound insulation layer 2 is fixedly installed above the fixing layer 1, and the lower sound insulation layer 3 is fixedly installed below the fixing layer 1. To ensure the stability of the device, the fixing layer 1 is made of a rigid material, such as a steel plate or an aluminum alloy plate. The fixing layer 1 is arc-shaped, and several sets of slots 8 are formed on the fixing layer 1. Limiting plates 4 are fixedly installed at both ends of the fixing layer 1, and several threaded holes 5 are formed on the limiting plates 4.

[0021] As one embodiment of this example, the upper sound insulation layer 2 is arc-shaped and fits against the outer side of the fixing layer 1. The upper sound insulation layer 2 is made of polyester fiber and is used to absorb noise and vibration. Several first clips 9 are fixedly installed on the side of the upper sound insulation layer 2 that is close to the fixing layer 1. The fixing layer 1 and the upper sound insulation layer 2 are fixedly connected by the first clips 9 and the clips 8. A tooth 6 is fixedly installed on the side of the upper sound insulation layer 2 that is away from the fixing layer 1. The tooth 6 is a semi-circular protruding tooth that contacts the inner side of the car tire during installation to ensure that the upper sound insulation layer 2 fits the tire and prevents displacement.

[0022] In one embodiment of this invention, the lower sound insulation layer 3 is arc-shaped and fits against the inner side of the fixing layer 1. The lower sound insulation layer 3 is made of vibration-absorbing material, such as rubber. Several second locking blocks 10 are fixedly installed on the side of the lower sound insulation layer 3 that is close to the fixing layer 1. The fixing layer 1 and the lower sound insulation layer 3 are fixedly connected by the locking of the second locking blocks 10 with the locking groove 8 below the fixing layer 1. The side of the lower sound insulation layer 3 away from the fixing layer 1 has a concave tooth 7. The concave tooth 7 matches the shape of the protrusion inside the car wheel hub. The locking of the concave tooth 7 with the wheel hub increases the stability of the device and prevents the device from shifting. The entire device is used in pairs and is symmetrically arranged between the car wheel hub and the tire. The device is installed with the wheel hub by locking the concave tooth 7 with the wheel hub. Then, several bolts are threaded onto the symmetrically arranged threaded holes 5. The two pairs of limiting plates 4 are fixedly connected by the bolts, thereby realizing the fixed installation of the device.

[0023] Working principle:

[0024] In use, the devices are installed in pairs on both sides of the car wheel hub, symmetrically positioned between the wheel hub and the tire. The devices are installed on the wheel hub by engaging with the protruding part inside the wheel hub through the concave teeth 7. Then, several bolts are threaded onto the symmetrically arranged threaded holes 5, and the two pairs of limiting plates 4 are fixedly connected by the bolts, thereby achieving the fixed installation of the devices.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
