Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub technology, and in particular to a safe and durable automotive wheel hub. Background Technology

[0002] Car wheel hubs are a crucial structural component of automobiles. Existing car wheel hubs use arc-shaped connecting ribs between the inner and outer rings to ensure overall strength. However, this requires mold forming during production, resulting in relatively low processing efficiency. Furthermore, the inner ring cannot be reinforced with additional components. For some double-ring wheel hubs, a reinforcing inner ring or structural component needs to be installed inside the hub. However, during overall installation, the mating positions between different components cannot be precisely isolated, making it difficult to guarantee internal installation accuracy during use. Additionally, the heat resistance of the mating areas is relatively poor. Utility Model Content

[0003] The purpose of this utility model is to provide a safe and durable automobile wheel hub. It features higher overall molding efficiency during production and is connected to the inner and outer sides using a flat structural surface. The flat structural surface is reinforced with circumferentially distributed reinforcing support bosses, which not only effectively ensures the overall structural strength but also reduces the difficulty of mold fitting during production and provides better heat dissipation during use. The reinforced structure on the inner side not only ensures internal structural strength but also meets the precise fitting requirements when installing a double-ring wheel hub. The reinforced support bosses on the inner side ensure reliable isolation space between the assembled components, thus ensuring better airflow between the inner and outer sides during use. Overall, it offers more reliable heat resistance and durability, and a longer service life.

[0004] The technical solution of this utility model is as follows: A safe and durable automobile wheel hub includes a cylindrical wheel hub body structure with its central axis pointing left and right. The outer side of the wheel hub body structure has an outer ring mounting post, and the left side of the wheel hub body structure has a cylindrical inner ring groove. The wheel hub body structure and the right side of the inner ring groove each have correspondingly distributed arc-shaped reinforcing support bosses. These reinforcing support bosses are composed of evenly distributed circumferentially distributed bosses. A set of symmetrically distributed reinforcing groups is located at the front and rear positions of the inner cylindrical face of the inner ring groove. The reinforcing combination limiting post consists of two upper and lower limiting mating posts, forming a reinforcing combination connecting groove between the two upper and lower limiting mating posts. An arc-shaped mounting auxiliary locking plate is provided at the upper and lower positions inside the inner ring groove of the wheel hub. A cylindrical central mounting mating connecting hole that penetrates the right side of the entire inner ring groove is provided at the center position of the right side of the wheel hub inner ring groove. Six circumferentially distributed integral locking and fixing holes are provided on the right end face of the inner ring groove of the wheel hub. A ventilation and safety mating hole that penetrates the right side of the entire inner ring groove is provided.

[0005] Furthermore, the ventilation safety mating hole consists of two cylindrical mating holes distributed front and rear.

[0006] Furthermore, the installation auxiliary mounting plate is connected to the reinforcing support boss at a similar location.

[0007] Furthermore, the side of the mounting auxiliary positioning plate near the cylindrical surface of the inner groove of the wheel hub has a hollow structure.

[0008] Furthermore, the mounting auxiliary positioning plate is made of metal and is connected to the inner cylindrical surface of the inner ring groove of the wheel hub by welding.

[0009] The beneficial effects of this utility model are: This invention offers higher overall molding efficiency during production and processing. The inner and outer sides are connected by a flat structural surface, and the flat structural surface is reinforced with circumferentially distributed reinforcing support bosses. This not only effectively ensures the overall structural strength but also reduces the difficulty of mold fitting during production and processing. It also provides better heat dissipation during use. The reinforced structure on the inner side not only ensures the internal structural strength but also meets the precise fitting requirements when installing double-ring hubs. The reinforced support bosses on the inner side ensure reliable isolation space between the assembled components, thereby ensuring better air circulation between the inner and outer sides during use. The overall heat resistance and durability are more reliable, and the service life is longer. Attached Figure Description

It boasts higher overall molding efficiency during production. The inner and outer sides are connected by a flat structural surface, with circumferentially distributed reinforcing support bosses on the flat structural surface. This not only effectively ensures the overall structural strength but also reduces the difficulty of mold fitting during production, and provides better heat dissipation during use. The reinforced structure on the inner side not only ensures internal structural strength but also meets the precise fitting requirements during double-ring wheel hub installation. The reinforcing support bosses on the inner side ensure reliable isolation space between the assembled components, thus ensuring better airflow between the inner and outer sides during use, resulting in more reliable heat resistance and durability, and a longer service life.

[0012] Preferably, the ventilation safety fitting hole 10 consists of two cylindrical fitting holes distributed front and back, which can ensure the ventilation volume during use and also ensure the strength of the main structure is relatively reliable.

[0013] Preferably, the installation auxiliary mounting plate 7 is connected to the reinforcing support boss 4 at a similar position, which improves the strength of the connection position, makes production and processing more convenient, and provides more space for the connection position.

[0014] Preferably, the side of the mounting auxiliary positioning plate 7 near the inner cylindrical surface of the inner ring groove 3 of the wheel hub has a hollow structure, which can provide reliable deformation space during auxiliary engagement and make the combination of auxiliary positions during engagement smoother.
