Description
Technical Field
The utility model belongs to the technical field of the knuckle technique that is used for the commercial car of vehicle especially and specifically relates to a knuckle of lightweight high strength.
Background
The steering knuckle is one of main parts on an automobile steering axle, can enable an automobile to stably run and sensitively transmit the running direction, has the functions of bearing the front load of the automobile, supporting and driving a front wheel to rotate around a main pin so as to enable the automobile to steer, and bears variable impact loads in the running state of the automobile, so that the steering knuckle is required to have high strength, meanwhile, unsprung mass has great significance on the stability and the controllability of the automobile, the effect of lightening 1 kilogram of unsprung mass is equivalent to lightening 15 kilograms of sprung mass, and under the condition that the sprung mass is not changed, lightening the unsprung mass can effectively improve the acceleration, the stability and the maneuverability of the automobile, and therefore a light-weight and high-strength steering knuckle is developed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome current defect, provide a knuckle of lightweight high strength, when having guaranteed knuckle structural strength, reduced the weight of knuckle, reached the purpose that makes its lightweight high strength.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a knuckle of lightweight high strength, includes integrated into one piece's axle journal, mounting disc and king pin installation ear, king pin installation ear opposition sets up the both ends at the mounting disc, is provided with the king pin hole on the king pin installation ear, and the top of one of them king pin installation ear is provided with steering connection hole, be provided with the braking mounting hole on the mounting disc, the end that the axle journal is located king pin installation ear is provided with the lightening hole.
As a preferred technical scheme of the utility model, the lightening hole is cylindrical, and the axis of lightening hole coincides with the axis of axle journal.
As a preferred technical scheme of the utility model, the outside end of king-pin hole is provided with the reinforced pipe, and the mouth of pipe department of reinforced pipe is slope form.
As an optimal technical scheme of the utility model, the tip that turns to the connecting hole is provided with slope form chamfer.
As an optimized technical scheme of the utility model, axle journal, mounting disc and swizzle installation ear are made by high strength impact-resistant material.
As an optimized technical scheme of the utility model, the tip opening part of lightening hole is provided with sealed apron.
Compared with the prior art, the beneficial effects of the utility model are that: this knuckle of lightweight high strength when having guaranteed knuckle structural strength, has reduced the weight of knuckle, has reached the purpose that makes its lightweight high strength, has alleviateed the unsprung mass, has effectively promoted the acceleration nature, the stability and the nature controlled of car.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1 journal, 2 mounting discs, 3 main pin mounting lugs, 4 main pin holes, 5 lightening holes, 6 steering connecting holes, 7 reinforcing pipes and 8 brake mounting holes.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a lightweight high-strength steering knuckle comprises an integrally formed shaft journal 1, a mounting disc 2 and a main pin mounting lug 3, wherein the shaft journal 1, the mounting disc 2 and the main pin mounting lug 3 are made of high-strength impact-resistant materials so as to ensure the strength of the steering knuckle after weight reduction, the main pin mounting lugs 3 are oppositely arranged at two ends of the mounting disc 2, a main pin hole 4 is formed in each main pin mounting lug 3, the steering knuckle is rotatably mounted on a front axle of an automobile through the main pin hole 4 in a manner of matching with the main pin, so that a front wheel can deflect a certain angle around the main pin to steer the automobile, a reinforcing pipe 7 is arranged at the outer side end of each main pin hole 4, the contact area between each main pin hole 4 and the main pin is prolonged, the anti-shearing performance of the main pin is improved, the pipe orifice of each reinforcing pipe 7 is in a slope shape, a bushing is convenient to mount, a steering connecting hole 6 is formed in the top of one main pin mounting lug 3 so that the steering energy is saved, the bearing bush is convenient to mount, the mounting disc 2 is provided with a brake mounting hole 8 for mounting a brake system of an automobile, the end part of the shaft neck 1, which is positioned on the main pin mounting lug 3, is provided with lightening holes 5, the lightening holes 5 are cylindrical, the central axis of the lightening holes 5 coincides with the central axis of the shaft neck 1, so that the dynamic balance of the shaft neck 1 is realized, the lightening holes 5 can greatly reduce the weight of a steering knuckle on the premise of ensuring the structural strength of the shaft neck 1, the unsprung mass of the automobile is reduced, and the end opening part of the lightening holes 5 is provided with a sealing cover plate so as to prevent sundries from being accumulated in the lightening holes.
