Because Chev is the senior proud car of a kind of high speed, the design of its steering ball end is at high class pavement, and domestic road surface road conditions are bad, is not fit to this vehicle '.Because, when road conditions were bad, automobile bumpiness was serious, added this chassis and weighed, the suffered impact of steering ball end, vibration are very serious, and its frequency that shakes is very high, very easily anti-wearing liner is damaged, after anti-wearing liner damages, bulb then can directly impact the very thin bulb housing of wall thickness, and because the free gap becomes big its impact, swing is more serious, and cause the distortion and the severe wear of bulb housing very soon, cause bulb to extract and cause the pernicious burst accident of wheel out.

In addition because the violent vibration of jolting, serious wigwag motion, the going up of bulb visit section with bulb mutually the weakness of transition will soon reach fatigue fracture and cause unpredictable major accident.

The generation of above accident, not only unpredictable, and car crash often, because bulb is in the small space place under the car, can't observe at all, hard to guard against, therefore, nobody dares present this car to take, major part is in shut down condition, causes very big loss for national wealth and personal safety, though claim damages to vehicle exported country, but thousands of cars can not normally use, and have caused great waste.The whole steering ball end of frequent replacing that also can only lean on that minority is used moves reluctantly, has caused the rising of using service expenditure, because its bulb and housing are non-disconnectable.

The purpose of this utility model just is to overcome existing above-mentioned shortcoming and defect in the prior art, and provide a kind of have relief bracket and double end bulb fixing, safety, reliable, the double end dual-hooking front suspension steering ball end being convenient to change.

The purpose of this utility model is to realize by following technical scheme: in existing car base space, do not changing under the preceding topic of other any parts, steering ball end is designed to have the new construction of two bulbs up and down, bulb is still hung with steering swivel and is connected on it, bulb is visited and is loaded in the hole of relief bracket bottom under it, the relief bracket top and the steering swivel of handbag shape are connected, its underpart one side has linked watt and the support of steering ball end lower surface has been caught, in case going up bulb splits off, relief bracket still can constitute a supporting construction with front suspension the steering ball end support is caught, and continue normally to use, in addition, strengthen with original lining cancellation and with bulb and removable housing, prevented deviating from of bulb, improved its intensity.

Therefore effect of the present utility model is significant:

The effect of double insurance has been played in the increase of relief bracket, not only can prevent the pernicious generation of falling wheel, the car accident of lying prone, and, can guarantee the cruising of vehicle.

The cancellation of bulb lining not only simplifies the structure, and the increase of bulb diameter is achieved, and shell thickness is increased, and has both increased contact bearing surface in both, has improved both impact strengths again, has prevented deviating from of bulb especially effectively.

Owing to other adjacent component is not done any change, therefore, has kept the integraty and the existing structure performance of existing vehicle, and, simple and easy to do, be convenient to change, a collection of car has been brought back to life in this key improvements design of particularly two-way bulb and relief bracket, has bigger economic benefit and realistic meaning.
