Abstract
An improved structure of a car front axle steering knuckle arm and a steering knuckle is formed by connecting the steering knuckle arm and the steering knuckle, the steering knuckle arm adopts a slant straight arm structure, a straight arm part is provided with connecting holes, cleat parts on the steering knuckle are provided with two positioning surfaces with positioning connecting holes, and the steering knuckle arm and the steering knuckle are positioned and connected by adopting studs, spring washers and nuts via the positioning surfaces and the positioning connecting holes. The improved structure of the car front axle steering knuckle arm and the steering knuckle is reasonable in structure, simpler in processing and assembly processes, low in manufacturing cost, easy to remodel and serialize, and capable of fast responding changeable market requirements.
Description
Technical field
The utility model relates to a kind of automobile front axle track arm and steering swivel improves structure, belongs to automobile component manufacturing technology field.
Background technology
The effect of automobile front axle track arm is to be connected with steering wheel, and the handling maneuver of steering wheel is directly delivered to the propons left and right wheels, completes motor turning.During running car, need frequently turn to, track arm need bear complicated reverse stress in this process.At present, track arm in existing model HG1060FD propons adopts space curved boom form, and adopt semi-round key location and taper hole connection mode between steering swivel, this connection mode need to be processed taper hole and the positioning spline at goat's horn position on steering swivel, simultaneously due to the track arm complicated structure, when processing circular cone positioning section and keyway, need to adopt special tooling, all make processing inconvenience, and the reject rate hinge is high, efficiency is lower.Track arm is vehicle key spare, needs after processing to detect a flaw, and by flaw detection, also finds track arm due to fault of construction, and off gauge is more.
Summary of the invention
The purpose of this utility model is, the defect that exists in order to solve former HG1060FD front axle steering knuckle arm and slewing journal structure, provide a kind of automobile front axle track arm and steering swivel to improve structure, and the original structure form is changed, improve its manufacturability, enhance productivity and economic benefit.
For achieving the above object, the utility model adopts following proposal:
Front axle steering knuckle arm described in the utility model and slewing journal structure, connected to form by track arm and steering swivel, wherein said track arm adopts oblique straight-arm structure, the straight-arm position is provided with connecting bore, on described steering swivel, the goat's horn position is provided with two locating surfaces, two locating surfaces are provided with the hole that is located by connecting, and adopt thru-bolt, spring washer and nut by above-mentioned locating surface and the hole that is located by connecting, track arm and steering swivel to be located by connecting.
By intensity calculate, the test of three-dimensional modeling optimization and vehicle bridge shows, the utility model performance is good, can meet operating needs fully, time-to-market length and the high problem of mold developing cost that original structure form defect causes have effectively been solved, reduce the materials'use amount, and be easy to remodeling and form seriation, can fast responding market conversion demand, obtained good economic and social benefit in actual production.
Description of drawings
Fig. 1 is that front axle steering knuckle arm described in the utility model and steering swivel improve structural representation.
Fig. 2 is that in the utility model, track arm improves schematic diagram.
Fig. 3 is that in the utility model, steering swivel improves schematic diagram.
In figure: 1-steering swivel, 2-thru-bolt, 3-spring washer, 4-nut, 5-track arm.
The specific embodiment
As shown in the figure, the utility model is the improvement of HG1060FD front-axle structure, change its track arm and the original taper hole of steering swivel location and connection mode into thru-bolt location and connection mode, wherein said track arm 5 adopts oblique straight-arm structure, the straight-arm position is provided with connecting bore, on described steering swivel 1, the goat's horn position is provided with two locating surfaces, the hole that is located by connecting is set on two locating surfaces, adopts thru-bolt 2, spring washer 3 and nut 4 by above-mentioned locating surface and the hole that is located by connecting, track arm 5 and steering swivel 1 to be located by connecting.
On steering swivel of the present utility model, the comformability change is carried out at the goat's horn position, guaranteeing under working strength and the hands-off condition of each parts, the scheme of optimizing structure, suitably strengthen upper goat's horn position, and at upper goat's horn position processing locating surface, and on locating surface drilling two hole that is located by connecting, avoid processing taper hole and positioning spline, the processing of simplifying steering swivel and track arm be connected technique, improved product design and productivity effect.
Improvement structure job operation described in the utility model:
1, steering swivel: adopt die-forged part, goat's horn carries out corresponding adaptive improvement on the steering swivel of original model HG1060FD propons, cancels taper hole, changes milling plane of orientation and the processing hole that is located by connecting into, and all the other processing technologys are with original model.
2, track arm: adopt die-forged part, make oblique straight-arm structure, straight-arm partly processes plane of orientation and the hole that is located by connecting.
3, above-mentioned part is connected with nut with thru-bolt, spring washer.
The utility model is with the steering swivel in the HG1060FD propons and track arm is located and type of attachment changes thru-bolt location and the form that is threaded into.Reasonable in design, processing and assembly technology are simpler, and low cost of manufacture is easy to remodeling and forms seriation, can change demand by fast responding market.
Be more than preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model, when the function that produces fails to exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
