Description

A emergent safe pendulum unit of tire burst for on wheel hub

Technical Field

The utility model relates to an automobile wheel hub specifically is an emergent safe pendulum unit of tire burst for on wheel hub.

Background

In order to guarantee smooth transportation, maintain personal and property safety of drivers and passengers, continuously improve vehicle safety standards and continuously obtain mandatory standards, such as GB/T7258-2017, JT/T1178.1-2018, JT/T1178.2-2019 and the like, the state requires that automobile tire burst emergency safety devices are required to be installed on part of vehicle steering wheels.

The tire burst emergency safety device developed internationally and domestically has two mature technical routes, and the industrialization is realized. One is groove filling type: the U-shaped groove for dismounting and mounting the tire is designed in the hub and is filled with the annular structural member, so that the situation that after a tire bead bursts, the tire sideslips fall into the U-shaped groove and is separated from the hub according to the tire dismounting principle, the hub directly contacts the ground, the ground friction force required by vehicle control is lost, and the tragedy of vehicle damage and people death is caused.

The other scheme is a lateral blocking scheme, a steel belt is assembled in an annular groove ring, N groups of pendulum assemblies are arranged on the steel belt, the pendulum assemblies are opened due to centrifugal force when a vehicle runs, when a tire bursts, a tire lip slides laterally, the pendulum assemblies are blocked by the opened pendulum assemblies and cannot fall into the annular groove ring, and the effect of preventing the burst tire from being separated from a hub is achieved.

The first groove filling type technical route is simple in structure, different products can be matched according to different U-shaped groove section sizes, the universality is poor, and the assembly requirements of diversified hub varieties on the market can not be met. And because the annular groove ring filled by the scheme is originally designed to be a structure special for assembling the tire, the assembly process is complicated after the annular groove ring is filled.

The second side direction blocks formula scheme, does not have the size requirement to wheel hub U type ring channel, fine solution market commonality problem to because only occupy local concave groove, still can adopt the original vapour of society to protect the instrument dismouting.

The two schemes have technical and cost advantages, and well solve the problems of economic loss and casualties caused by tire burst in the developed and busy logistics traffic of the modern society, and make positive contribution to the safe and orderly operation of the economic society.

Above two kinds of schemes, all are with independent product assembly, install in wheel hub, have following defect:

1. and resetting the resources. Because the tire burst emergency safety device is an independent assembly, more than 40% of structures are only used for connecting parts into a whole, the structure and the abundant strength of the wheel hub are not utilized, and the tire burst emergency safety device belongs to resource resetting.

2. Heavy weight and high oil consumption. When the automobile runs and the wheels move at high speed, the generated centrifugal force and the self weight greatly consume the oil consumption of the running of the automobile.

3. The cost is high. Because the products are supplied in independent assemblies, the production and manufacturing process cost is not intensified with the hub, and the product cost is higher.

The scheme that patent number is ZL 201821451984.5 and provides does not have the size requirement to wheel hub U type ring groove, fine solution market commonality problem to because only occupy local concave groove, still can adopt original vapour of society to protect the instrument dismouting.

However, the solution has the following improvements:

1. the structure is complicated, and the reliability guarantee requirement is high.

2. The processing technology is complex, various molding technologies such as casting, heat treatment, mechanical processing, stamping, welding and the like are designed, and the requirement links for the quality control capability of the technology are more.

3. The appearance is rough, and the sharp angle protrudes more.

Disclosure of Invention

The utility model discloses a solve resource resetting, the heavy, oil consumption height of the background art that provide, with high costs technical problem, provide a special emergent safe pendulum unit that blows out that is used for on the wheel hub.

Therefore, the technical scheme of the utility model is, an emergent safe pendulum unit of tire burst for on wheel hub, including automobile wheel hub, automobile wheel hub in still include rim, spoke, the spoke supports the rim, and is equipped with the bead seat through the rim in the rim, the rim bottom still includes annular groove circle, its characterized in that: the pendulum bob units are uniformly arranged on the annular groove ring, are fixed on the annular groove ring and are finally combined with the hub into a whole;

two side edges of the vertical side surface of the pendulum bob base are respectively provided with a first hinge hole and a second hinge hole, the vertical side surface is hollowed in the middle of the first hinge hole and the second hinge hole, and a silicone tube is arranged at the hollowed-out position;

the lower part of the pendulum is provided with an opening to form a pendulum left ear and a pendulum right ear, and the vertical side surface of the pendulum base is embedded between the pendulum left ear and the pendulum right ear;

at the moment, the rotating shaft rivet pin sequentially penetrates through the pendulum mass left lug, the hinge hole I, the silicone tube and the hinge hole II, finally penetrates out through the pendulum mass right lug, and is riveted through a riveting machine to form a pendulum mass unit after being sleeved with the flat gasket.

The further improvement lies in that: the rotating shaft rivet pin penetrates through the pendulum bob right lug, the hinge hole II, the silicone tube and the hinge hole I in sequence or penetrates out of the pendulum bob left lug in sequence, and is riveted through a riveting machine to form a pendulum bob unit after being sleeved with the flat gasket.

The further improvement lies in that: the outer diameter of the silicone tube forms an extrusion state at the hollow part and the vertical side surface of the pendulum bob base.

The further improvement lies in that: the pivot rivet round pin tip become the C type, pendulum left side ear or pendulum right side ear still be equipped with the lug outward, the C type and the lug cooperation of pivot rivet round pin tip form the location, wherein pivot rivet round pin riveting back is fixed state relatively, pendulum this moment along pivot rivet round pin axial motion, the pendulum opens the location promptly after the C type and the lug location of pivot rivet round pin tip, reaches the emergent safe pendulum unit's of blowing out function.

The further improvement lies in that: and the pendulum bob units are fixed on the annular groove ring in various fixing modes including bonding, welding and riveting.

Has the advantages that:

the utility model discloses pendulum unit utilizes the frictional resistance of silicone tube, realizes the closure of pendulum and opens the location, and the structure is simpler, and the subassembly can be installed or the welding/bond on wheel hub or annular steel band, realizes the function of the emergent safe pendulum unit of blowing out.

Because the silicone tube external diameter is extruded by pendulum base, through the diameter or the elasticity of adjusting the silicone tube, can obtain required speed of a motor vehicle of opening. The silicone tube generates friction force on the rotating shaft rivet pin, and the pendulum bob can be opened only under the action of certain external force (centrifugal force is suitable for a tire burst emergency safety device); and the pendulum bob is limited by the limit structure of the pendulum bob base and then stays at a specific position.

The pivot rivet pin becomes fixed state relatively the pendulum after riveting, just in order to make it have the function of location.

The structure and the processing technology of the utility model are simpler; the cost is lower, the hub is suitable for mass production and manufacture, and the hub is very convenient to mount for the formed hub or the hub in use.
