Technical field

The utility model relates to a kind of automotive safety safety device, relates in particular to a kind of short crown three-clove style inner supporting body of safety tyre.

Background technology

At present; In order to prevent that the motor tire back of blowing out from taking place out of control and even safety device that topple is the wheel that different materials processing is installed on the vehicle hub steel ring; Purpose is to make vehicle when blowing out generation; Its wheel plays the effect of support tire, avoids bigger danger and accident take place as far as possible, and makes vehicle can continue to exercise a segment distance.This safety device is also referred to as tire inner supporting body technology.Several kinds of tire safety devices that adopt high-strength engineering plastic to constitute are disclosed in the existing patent; Disclose a kind of wheel of being processed by high-strength engineering plastics that is installed in the vacuum automobile tire like Chinese patent ZL96219610.X " automobile flat tire safety device ", wheel supports car body and continues to slide to guarantee safety when blowing out.It comprises the cover keep lever in vacuum tire and the vacuum tyre, and cover keep lever is an annular arrangement, and the ring heart is sleeved on the tire wheel hub, and the external diameter of annulus is less than the diameter of tire, and the width of annulus is less than the width of tire; Cover keep lever is processed by high-strength engineering plastics.

Existing tire inner supporting body technology is because its inner supporting body annulus be whole, and in the process of implementing, during particularly to the short crown tire of civil car, existing inner supporting body is unfavorable for installation.Inner supporting body receives impact and can deform when blowing out, inner supporting body can not freely roll on the wheel hub steel ring, and when slight, automobile generation lateral deviation when serious, will cause great personnel casualty accidents.

Summary of the invention

The purpose of the utility model provides a kind of being beneficial to and installs and the short crown three-clove style inner supporting body of safe and reliable safety tyre.

In order to realize above purpose, the utility model has adopted following technical scheme: a kind of short crown three-clove style inner supporting body of safety tyre, ring and outer shroud in comprising; On the anchor ring of the ring outside, the interior side ring surface of interior ring was provided with wheel hub steel ring rim line and cooperates lines in outer shroud rotated and is located at, and the interior side ring surface obvolvent of interior ring is on the wheel hub steel ring; In be equipped with a fracture, interior ring outside anchor ring is provided with annular boss, outer shroud is a three-clove style; Each outer shroud lobe two ends is provided with negative and positive and connects the position; Three outer shroud lobes connect the position through negative and positive and lock into ring by attaching parts, and each outer shroud lobe is made up of becket and buffering ring, and the side ring surface is provided with and the interior groove that encircles the annular boss coupling of outside anchor ring in the becket; Side ring surface obvolvent is on the anchor ring of the interior ring outside in it; Becket outside anchor ring is provided with annular groove, and the side ring surface is provided with the annular protrusion that the annular groove with becket outside anchor ring is complementary in the buffering ring, and the side ring surface is entrenched on the anchor ring of the becket outside in the buffering ring.Utilize inner supporting body to be made up of interior ring and outer shroud, outer shroud is the structure of three-clove style, and the structure be made up of becket and buffering ring of each outer shroud lobe, makes inner supporting body be easy to install, because becket, has strengthened when blowing out, the withstand shocks ability of load of inner supporting body.

Be provided with positive stop lug boss in the annular groove of said becket outside anchor ring, the annular protrusion of the interior side ring surface of said buffering ring is provided with the limited impression with the positive stop lug boss coupling of becket outside anchor ring.

The negative and positive at said outer shroud lobe two ends connect negative and positive that the position comprises becket and connect the position and is connected the position with the negative and positive of buffering ring, and the negative and positive of becket connect the position one section convexity that stretches out, anchor ring formation continuous circular shape face outside its convex surfaces and the buffering ring.This kind structure has improved the buffer capacity of inner supporting body, has strengthened the ability of bearing instantaneous load simultaneously.

Said becket two sides are provided with shrinkage pool.In inner supporting body when work,, high-speed friction can produce a large amount of heats, this kind structure can make inner supporting body can be when work quick heat radiating.

The utility model adopts above technical scheme, utilizes it to be made up of interior ring and outer shroud, and outer shroud is a three-clove style; And the structure that each outer shroud lobe is made up of becket and buffering ring, when motor tire was blown out, the inside face of tire was fitted on the outer shroud of being made up of buffering ring and becket; The impact loading that receives is on outer shroud; Outer shroud is rotating on interior ring under the effect of impact load, makes the momentum of impact load change into the rotation momentum of outer shroud, thereby lets impact load effectively dissolved; The outer shroud of short crown three-clove style inner supporting body lands simultaneously; Do not allow the automobile occurrence of tilting to cause great personnel casualty accidents, realized being easy to installing, strengthened the ability and the rapid heat dissipation of the load that when blowing out, withstands shocks.
