Abstract

The invention provides a steering knuckle component used for an independent suspension system. A steering knuckle body extends towards the same side to form brake installation bases used for avoiding a main pin hole. The steering knuckle can be provided with an oil brake of the corresponding tonnage. Front wheel positioning parameters are set on the steering knuckle, and the driving stability, handling stability and tire returning performance of an automobile can be well ensured. A lightweight design concept is added to the steering knuckle, and the steering knuckle component is simple in structure and convenient to machine. The steering knuckle is applicable to a 2.8 T independent suspension front axle.

Description

A kind of steering knuckle member for independent suspension system
Technical field
The present invention relates to automotive steering structure, be specially a kind of steering knuckle member for independent suspension system.
Background technology
Along with the development of Independent Suspension, from car to medium bus to such an extent as to motor omnibus, all constantly use independent suspension, independent suspension has larger change to passenger vehicle traveling comfort.But the safety component of most critical is steering swivel in independent suspension, steering swivel is also along with different suspension property claimed structures is varied.
Independent suspension steering knuckle member and dependent suspension steering knuckle member have the difference of essence, and independent suspension steering knuckle member mainly connects upper lower cross arm respectively, and dependent suspension steering knuckle member is then connect vehicle bridge by a stub, and half shaft portion is connected with wheel.Certainly upper lower cross arm and steering swivel is also had to be connected by intermediate structure.Because wheel and steering swivel only relatively rotate, turning to of automobile acts on track arm by steering track rod, and wheel angle is changed, so the major part in steering swivel or automotive steering structure.But current independent suspension steering knuckle member generally can only be equipped with gas and stop, this have impact on the application of independent suspension on medium bus.
Summary of the invention
The object of the present invention is to provide a kind of steering knuckle member for independent suspension system that can be equipped with oil and stop.
The invention provides a kind of steering knuckle member for independent suspension system, comprise the mounting seat of brake being extended to form to avoid kingpin bore by steering swivel body towards the same side.
Preferably, steering swivel is provided with sensor mounting hole, and sensor mounting hole axis and semiaxis axis formed plane are perpendicular to the projection of stub at semiaxis Normal plane.
Preferably, steering swivel is integrally formed with track arm.
Preferably, track arm lower planes is vertical in the projection of semiaxis Normal plane with stub, and vertical with drg side profile face.
Preferably, stub becomes 11.5 ° with semiaxis normal plane, and namely Kingpin inclination angle is 11 ° of camber angles is 0.5 °, and kingpin caster angle is 3 °.
Beneficial effect:
1, the present invention can be equipped with oil and stops, and can be adapted to the steering knuckle member of 2.8T independent suspension, actv. solves the application problem of this tonnage medium bus independent suspension, and oil is stopped the outfit on this steering swivel, this steering swivel is used more extensive;
2, the Front wheel Alignment Parameters this steering swivel set well ensures the stationarity of running car, road-holding property and tire return performance;
3, this steering swivel carries track arm, ensure that the positional precision of steering ball end;
4, adopt weight-saving structure design, and structure design is simpler, is convenient to processing, its manufacturing cost is effectively reduced.

Detailed description of the invention
In order to make the present invention be easy to understand on 26S Proteasome Structure and Function, below in conjunction with concrete diagram, set forth the present invention further.
See shown in Fig. 1 to Fig. 4, taper hole 1 tapering installed by stub is 1: 10, and large footpath is 31.9mm, and path is 28.9mm.Stub and semiaxis normal plane are 11.5 °, and namely Kingpin inclination angle is 11 °, and camber angle is 0.5 °, and kingpin caster angle is 3 °.The stationarity of running car, road-holding property and tire return performance can be ensured so well.Fig. 1 only show Kingpin inclination angle and camber angle sum is 11.5 °, and kingpin caster angle will assemble up could embody in integral structure with upper lower cross arm, therefore does not indicate in Fig. 1.
Shown in Figure 2, mounting seat of brake 3,4 is extended to form towards the same side by steering swivel body, is formed and supports separately, avoid kingpin bore, thus can install gas and stop, can install again oil and stop, can meet the needs of medium bus independent suspension.Steering swivel loads after in suspension, and the plane formed by the axis of the mounting hole on mounting seat of brake 3,4 is perpendicular to the ground, and at this moment angle formed by this plane and stub line is kingpin caster angle.Axis and the semiaxis axis formed plane of sensor mounting hole 6 are parallel to horizontal surface, namely vertical in the projection of semiaxis Normal plane with stub.This steering swivel is integrally formed with track arm 2, does not need just directly to install steering track rod additionally by track arm.Track arm 2 lower planes is vertical in the projection of semiaxis Normal plane with stub, and vertical with drg side profile face 5, thus simplifies the structure of this steering swivel.Therefore, a vertical surface reference corresponding with it can both be found in these faces above-mentioned, while simplifying its structure, also simplify processing technology.Steering swivel, owing to being important safety parts, need adopt the processing mode of forging, and in forging, Simplified flowsheet can reduce manufacturing cost significantly.
More than show and describe framework of the present invention and advantage functionally.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
