Problems solved by technology

However, this technical solution still has some defects in use, such as the unreasonable cross-sectional shape of the safety device, and the force is too concentrated; the friction between the inner and outer rings of the safety device heats up during use, and it is very easy to damage

Embodiment Construction

[0011] The technical solutions of the present invention will be further described below in conjunction with the embodiments in the accompanying drawings.

[0012] Such as figure 1 , 2 As shown, the safety device of the present invention is composed of an inner ring 2 installed on the outside of the hub 6 and an outer ring 1 sleeved outside the inner ring 2 . The outer ring is composed of two semi-circular rings 1.1 and 1.2, and the semi-circular rings 1.1 and 1.2 are locked on the inner ring 2 through special bolts 3 and nuts 4 . The inner surface of the inner ring 2 matches the shape of the outer surface of the hub 6 and can be firmly in contact with the hub. The inner ring is made of modified engineering plastics, which has a certain degree of elasticity, so that the outer ring and the hub are more firmly connected.

[0013] Figure 4 Represented is the schematic diagram of the I-shaped cross-sectional shape of the attached wheel in the prior art. Depend on figure 2 A...

Abstract

The present invention relates to a car type safety device for preventing danger from taking place when the tyre is blown out. Said device includes an inner ring and an outer ring, inner side of the inner ring is matched with the form of outer side of hub, the outer ring formed from two semi-rings is cover-mounted on outer side of inner ring, the described two semi-rings are connected and locked by using belt and nut to form close contact with inner ring. The cross-section of outerring is made into the H form, between its upper portion, lower portion and vertical portion there is an arc transition, the inner side of outer ring is equipped with an U-shaped groove whose interior is filled up with lubricating liquid.

Description

technical field [0001] The invention relates to a safety device for avoiding the danger of tire bursting, in particular to the improvement of the structure of the attached wheel made of high-strength material installed in the tubeless tire. Background technique [0002] At present, the safety device to prevent tire blowout is to install the attached wheel on the hub in the tubeless tire, so that the attached wheel plays the role of the tire when a sudden tire blowout occurs during driving, avoiding greater dangers and accidents, and ensuring that the vehicle can continue to run. Drive a certain distance away from the dangerous road section. The applicant has also designed a tire safety device made of high-strength engineering plastics for this reason, and has applied for a Chinese patent (application number 96219610.X). However, this technical solution still has some defects found in use, such as the unreasonable cross-sectional shape of the safety device, and the force is ...
