Embodiment Construction

[0027] The present invention as Figure 1-3 shown.

[0028] A wheel hub with a self-contained tire burst emergency device, including a car wheel hub, the car wheel hub also includes a rim 1 and a spoke 2, the spoke 2 supports the rim 1, and the rim 1 is provided with a bead seat 4 through the rim 3, The bottom of the rim 1 also includes an annular groove ring 5, on which a plurality of uniform protrusions 6 are directly arranged, and the plurality of protrusions 6 form a tire burst emergency safety device on the annular groove ring 5. device.

[0029] The plurality of protrusions 6 form a tooth structure and are arranged in a staggered manner.

[0030] The plurality of protrusions 6 may be in the form of a rectangle, and are arranged axially on the annular groove ring 5 to form a staggered layout.

[0031] The plurality of protrusions 6 are made by rolling, spinning or stamping on the annular groove ring 5, and grooves 7 are correspondingly formed on the other side of the a...

Abstract

The invention discloses a hub with a tire burst emergency device which comprises an automobile hub body, the automobile hub body further comprises a rim, spokes and a spoke supporting rim, a tire beadseat is arranged in the rim through a wheel flange, an annular groove ring is further arranged at the bottom of the rim, a plurality of protrusions are evenly arranged on the annular groove ring, anda plurality of grooves is formed in the periphery of the annular groove ring. The plurality of bulges forms a tire burst emergency safety device on the annular groove ring; protrusions are formed byrolling or spinning or stamping on the annular groove ring, grooves are correspondingly formed in the other face of the annular groove ring, and therefore the protrusions and the annular groove ring form the integrated hub with the tire burst emergency device. The structure of an existing hub is changed, and the tire burst emergency safety device and the hub are combined into an integrated structure; the improved wheel hub can be engaged with a flat tire after tire burst in a grading manner, so that the flat tire cannot slide laterally, and the technical requirements that the flat tire cannotbe separated from the wheel hub after tire burst, the ground and the wheel hub are effectively isolated, and the control friction force is kept are met.

Description

technical field [0001] The invention relates to an automobile wheel hub, in particular to a wheel hub with a tire blowout emergency device. Background technique [0002] In order to ensure smooth transportation and maintain the personal and property safety of drivers and passengers, the state has continuously improved vehicle safety standards and continuously issued mandatory standards, such as GB / T7258-2017, JT / T1178.1-2018, JT / T1178.2-2019 etc., requiring the steering wheels of some vehicles to be equipped with emergency safety devices for automobile tire blowouts. [0003] There are two mature technical routes for tire burst emergency safety devices developed internationally and domestically, which have been industrialized. One is the groove filling type: the U-shaped groove in the wheel hub designed for dismounting the tire is filled with a ring structure to prevent the tire from slipping into the U-shaped groove after the bead bursts, and the principle of tire removal ...
