Abstract

A gantry type bracket knuckle comprises a platy knuckle body, a bent upper lug seat with a dip angle alpha, a bearing seat, a bent gantry type supporting seat with a dip angle beta, a left stand column and a right stand column, wherein the upper lug seat is located at the upper end of the knuckle body backwards, the bearing seat is arranged in the middle of the knuckle body and protrudes forwards, the gantry type supporting seat is located at the lower end of the knuckle body backwards, the left stand column is arranged on the left of the lower portion of the knuckle body, and the right stand column is arranged on the right of the lower portion of the knuckle body; an upper lug seat hole is formed in the upper lug seat, and a ball pin supporting hole is formed in the middle of the gantry type supporting seat. The gantry type bracket knuckle has the advantages that a driver can easily and conveniently rotate a steering wheel to better feel road conditions, fatigue of the driver driving on an uneven road is relieved, the direction is more stable on a bumpy and rugged road, controllability is better, the acting force between wheels and the road is transmitted to the steering wheel as little as possible, hand hit is prevented, and the driver can control the steering wheel more easily.

Description

A kind of gantry type bracket knuckle

Technical field

The invention belongs to automobile component structure technology, especially relate to the steering knuckle structure of car of a kind of gantry type bracket.

Technical background

Knuckle is one of major part on steering axle of automobile, although it is of a great variety for existing knuckle, different, especially in the selection of material, all has nothing in common with each other in processing technique and on heat treatment method.But structurally still there is the defect affecting deflecting roller location parameter, such as: it is all monaural formula that the ball pin of the knuckle of independent suspension props up bearing, the installation site deflection vehicle interior side of ball pin, causes kingpin inclination big or kingpin offset is big, affect motor turning performance.

Summary of the invention

For the deficiency that above-mentioned prior art exists, the invention provides a kind of compact conformation, the rational knuckle of caster.

It is an object of the invention to realize by following technical solution.

A kind of gantry type bracket knuckle, the invention is characterised in that, including: in plate-like knuckle body, it is positioned at knuckle body upper end and has a bending and the upper ear seat with inclination alpha backward, it is opened in the middle part of knuckle body and the bearing block highlighted forward, it is positioned at knuckle body lower end and has a bending and the planer-type with angle of inclination beta to prop up bearing backward, being set to left column on the left side of knuckle body bottom, the right side is set to right column；Upper ear seat offers upper ear seat hole, props up at planer-type and in the middle part of bearing, offer ball stud support holes.

The invention has the beneficial effects as follows: can adjust deflecting roller kingpin inclination is suitable angle, reduce kingpin offset and make deflecting roller location parameter tend to reasonable.The advantage being reacted to driver's practical operation aspect is: the control stability of vehicle is good.Driver can rotate steering wheel easily, feels road conditions；Rugged road surface can prevent road surface to the recoil of steering wheel, hired roughneck jolting, alleviate the fatigue of driver when travelling on uneven road surface.
