DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Such as Figures 1 to 7As shown in the figure, a heat-resistant combined component of a wheel hub unit includes a cylindrical main body combined connecting column 1. At the center position of the right end face of the main body combined connecting column 1, there is an integrally formed cylindrical reinforcement combined connecting column 7, which can be combined with the mating hole at the wheel hub installation position during mating, ensuring better tightness and higher mating strength at the combined connecting position. At the center position on the left side of the main body combined connecting column 1, there is a cylindrical central assembly connecting hole 2 that completely penetrates the whole right side, and it is mated with the combined column at the center position during installation. At the connection position between the front of the reinforcement combined connecting column 7 and the main body combined connecting column 1, there is an anti-loosening fastening mating groove 8 that communicates with the central assembly connecting hole 2, which can be mated and connected from the side. On the left end face of the main body combined connecting column 1, there are fan-shaped heat insulation safety mating grooves 3 evenly distributed in a circumferential manner, which can play a reliable heat insulation role during use. At the middle position of the heat insulation safety mating groove 3, there is a fan-shaped ventilation safety mating groove 4 that penetrates the whole in the left-right direction, which can better ventilate and dissipate heat in cooperation with the space at the installation position, ensuring better heat resistance at the installation position. At the outer side position of the heat insulation safety mating groove 3, there is an arc-shaped associated locking connecting groove 5, which can be tightly mated with the associated component, ensuring better connection firmness at the fastening position, having a reliable anti-loosening effect, and ensuring stronger durability at the fastening position. At both ends of the associated locking connecting groove 5, there is a fastening mating connecting hole 6 respectively, which is used for overall fastening connection with fastening bolts. It can be mated and connected with the installation position of the wheel hub unit during use, playing a role of transitional connection. During use, it can play a role of associating and fastening the combination at the fastening position. And through the setting of heat insulation grooves on the main body structure, it has reliable heat resistance during use, making the wheel hub unit safer during use and more durable. During later maintenance, this component can replace the main body of the wheel hub unit for wear, and only this component needs to be replaced, which can effectively improve the convenience during maintenance and make the service life of the wheel hub unit longer.

[0021] Preferably, the outer side surface of the ventilation safety mating groove 4 is parallel to the side surface at the corresponding position on the outside of the heat insulation safety mating groove 3, making the stability of the main body structure better and more convenient for production and processing.

[0022] Preferably, the depth of the associated locking connecting groove 5 is the same as the depth of the ventilation safety mating groove 4, making the strength of the main body structure better and further improving the structural stability during use.

[0023] Preferably, the depth of the ventilation safety mating groove 4 is less than half of the thickness of the main body combined connecting column 1, which can further ensure the strength of the overall structure and better mating safety during use. If the depth is too large, it will affect the durability of the whole during use.

[0024] Preferably, an installation combination convenient chamfer structure is provided at the outer edge position of the central assembly connection hole 2, which is more convenient during assembly combination, has the function of cooperation guidance, and can improve the cooperation efficiency during combination.

[0025] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements or replacements can be made, and these improvements or replacements should also be regarded as the protection scope of the present invention.
