INVENTOR fa/VEGA" i L LYNDON STEERING KNUCKLE F ed Oct.
May 5, i925.
Patented May 5, 1925.
UNITED STATES LAMAR LYNDON, OF NEW YORK, N. Y.
STEERING KNUCKLE.
AppIication filed October 17, 1821. Serial No. 508,236.
To all whom it may concern Be it known that I, LAMAR LYNDON, a citizen of the United States, and resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Steering Knuckle-s, of which the following is a specification.
My invention relates to steering knuckles for light weight motor vehicles.
In the construction of many types of motor cars, particularly where the cars are comparatively light in weight, the axle is made either of thin tubing, or of thin steel having a section of different shape. The steering knuckle must have an ample bearing area for the knuckle pin, and it has been customary, up to this time, to provide a casting for this purpose, having a cup, or pocket, into which the end of the axle is accurately fitted and brazed. This standard construction requires the use of a comparatively heavy and expensive casting, because experience has shown that the depth of the cup, or pocket, must be approximately twice the diameter or greatest cross sectional dimension of the axle in order to insure ample contact and brazing surface between the two parts which are to be united. At the cup end, the casting is spread out in the form of a yoke for the reception of the knuckle pin. Not only does this construction involve a casting of considerable length, with correspondingly great weight and cost, but there is, besides, always the danger that the joint between the casting and the axle may lead to serious troubles if the brazing is defective in any way.
My invention provides means for producing a steering knuckle that is light in weight, cheap of construction, and reliable in its adjustment to the axle ends. It isparticularly adapted for motor vehicles of comparatively light weight, wherein the axle is made of thin metal, such as tubing or thin steel stamped sections. Other novel and use ful features of my invention will appear from the specification which follows.
Referring to the drawings:
Figure 1 is a side elevation, partly in section, of the attachment which I provide for the steering knuckle, together with wheel spindle and steering knuckle spindle in place. Figure 2 is a sectional view of my attachment along the line 2-2 of Figure 1.
In these figures, 1 is a casting similar in form to the ordinary cast-iron T pipe-fitting. Through one arm of this T shaped casting is passed the end of the axle 3, which fits tightl in the opening and is brazed thereto. it an angle to the axle 3, shown in the drawings as a right angle, is the other arm of the T casting, 4. Into the opening of this arm 4:, is driven a bushing 5, which passes through holes in the axle 8 registering with the opening of the arm 4 of the casting. The bushing 5 is bored to receive the knuckle spindle 6.
Clearly, this construction not only reduces. the length, weight and cost of the casting, as compared with the standard construction of today, but its reliability and efiiciency are not dependent on the character or quality of the joint between the axle and the casting, since the casting can not be separated from the axle, except by complete rupture of the end of the axle itself.
My invention is not limited to the particular form 01": construction shown in the drawings, the form of knuckle pin and of wheel spindle, as illustrated, being merely indicative of how my attachment may be used for the purposes herein described. My invention is equally applicable for the well known forms of spindles having double bearing yoke ends, instead of the type shown. Other modifications may be made in my invention without departing from its spirit, by those familiar with the art.
I claim:
1. In a connection between an axle and a spindle, a member surrounding said axle and co-operating therewith to provide a bearing for said spindle, said spindle passing through both, said axle and said member.
2. The combination with an axle, of means for. connecting a spindle thereto, which means comprise a bearing for said spindle through said axle, and a member completely surrounding said axle and providing extensions for said bearing.
3. In a joint between an axle and a spindle, said axle being provided with a trans verse hole, a member surrounding said axle and having a hole registering with said first mentioned hole, and a bushing fitting into said two holes and adapted to receive said spindle.
4E. The combination with an axle and a spindle rotatably connected therewith, of a member surrounding said axle, said axle and said member being provided with a hole adapted to receive said spindle.
5. The combination With an axle made of metal and having a comparatively small area of cross-section, of a reinforcing mem ber fitted around said axle, a hole being pro- 5 vided through said axle and said reinforcing member, and a bushing fitting into said hole. 6. The combination with an axle made of hollow tubing and having a transverse hole therethrough, of a T-shaped jacket, one arm of said jacket surrounding said axle, the 10 LAMAR LYN DON.
