Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] With reference to Figures 1-4 The utility model provides an embodiment: half trailer tire burst emergency locking safety protection device, including wheel hub main part 1 and spoke 2, spoke 2 sets up in wheel hub main part 1 inside center front, the first support ring 3 is equipped in wheel hub main part 1 outside center upper reaches, the second support ring 4 is equipped in wheel hub main part 1 outside center lower reaches, the first support ring 3 and the second support ring 4 outside wall center place is circularly arranged and is equipped with multiple fixer 5, the first support ring 3 one end part is equipped with shaft pin 6, the first support ring 3 other end part is equipped with connecting adjustment device 7, through connecting adjustment device 7 makes it satisfy the staff and can adjust locking nut 703 according to the different size of wheel hub main part 1 adjustment adaptation, thereby improved the versatility and adaptability of device, the shape of first support ring 3 and second support ring 4 is semicircle ring respectively, through the semicircle ring design of first support ring 3 and second support ring 4 makes the support ring when unfolding can form a complete circular structure, provides uniform support force, the other end of shaft pin 6 and the second support ring 4 between connection, through shaft pin 6 makes it ensure the stable connection between the first support ring 3 and the second support ring 4, forms a linkage structure.

[0029] As Figure 4 Shown, the first support ring 3 and the second support ring 4 outside center front and rear are circularly arranged and are equipped with multiple self-lubricating devices 8, and the self-lubricating device 8 includes a microporous groove 801, the microporous groove 801 is arranged on the outer wall of the first support ring 3, and a self-lubricating material 802 is filled in the inner center of the microporous groove 801. When the first support ring 3 and the second support ring 4 move relative to the wheel hub or other components, the self-lubricating material 802 in the microporous groove 801 is continuously released, ensuring stable lubrication during the entire working process, effectively reducing the friction and wear between the support ring and the wheel hub or other components, and improving the reliability and service life of the device. The self-lubricating material 802 is graphite, which has a very low friction coefficient and can form a thin lubricating film on the friction interface, effectively reducing friction and maintaining its lubricating properties in high-temperature environments without decomposition or failure.

[0030] As Figure 3As shown, the connection adjusting device 7 comprises two square grooves 701, which are respectively arranged at one end of the first support ring 3 and the second support ring 4 outside the center, and an arc-shaped screw 702 is arranged between the one end of the first support ring 3 and the second support ring 4. The two ends of the arc-shaped screw 702 respectively penetrate the two square grooves 701 and reach the inner wall of the two square grooves 701. A locking nut 703 is threadedly connected to the outer side of the two ends of the arc-shaped screw 702. The first support ring 3 and the second support ring 4 are connected through the arc-shaped screw 702, and the locking nut 703 is limited, so that the staff can adjust the locking nut 703 according to the different sizes of the hub body 1 to adjust and adapt, thereby improving the versatility and adaptability of the device.

[0031] A tooth-shaped washer 704 is arranged at the center of the lower end surface of the upper two locking nuts 703 and the upper end surface of the lower two locking nuts 703. A tooth-shaped sleeve groove 705 is arranged at the center of the lower inner wall of the upper square groove 701 and the upper inner wall of the lower square groove 701. The two tooth-shaped sleeve grooves 705 are respectively connected with the two tooth-shaped washers 704. When the locking nut 703 is tightened, the tooth-shaped washer 704 is subjected to pressure, and the tooth-shaped structure begins to be embedded in the inside of the tooth-shaped sleeve groove 705, so that additional friction is generated. The locking performance of the locking nut 703 is significantly improved, the loosening of the locking nut 703 is avoided, the normal use of the locking nut 703 is affected, and the stability is improved.

[0032] Working principle: when the semi-trailer tire burst emergency locking safety protection device is used, the first support ring 3 and the second support ring 4 are designed as semicircular rings, so that the support ring can form a complete circular structure when it is unfolded, and uniform support force is provided. The shaft pin 6 ensures the stable connection between the first support ring 3 and the second support ring 4, forms a linkage structure, connects the first support ring 3 and the second support ring 4 through the arc-shaped screw 702, and limits the locking nut 703, so that the staff can adjust the locking nut 703 according to the different sizes of the hub body 1 to adjust and adapt, thereby improving the versatility and adaptability of the device.

[0033] When the locking nut 703 is tightened, the tooth-shaped washer 704 is subjected to pressure, and the tooth-shaped structure begins to be embedded in the inside of the tooth-shaped sleeve groove 705, so that additional friction is generated. The locking performance of the locking nut 703 is significantly improved, the loosening of the locking nut 703 is avoided, the normal use of the locking nut 703 is affected, and the stability is improved.

[0034] When the first support ring 3 and the second support ring 4 and the wheel hub or other components will produce relative movement and friction, the continuous release of the self-lubricating material 802 in the micro-hole groove 801 ensures that a stable lubricating effect is provided throughout the working process, which meets the requirements of effectively reducing the friction and wear between the support ring and the wheel hub or other components, thereby improving the reliability and service life of the device, and finally when the semi-trailer vehicle has a tire burst, the first support ring 3 and the second support ring 4 form a solid support structure, preventing the wheel hub from directly contacting the ground, ensuring the stability of the vehicle after the tire burst, and reducing the occurrence of serious traffic accidents.

[0035] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
