804,328. Ball and socket joints. THOMPSON PRODUCTS, Inc. July 16,1956 [July 21, 1955], No. 21952/56. Class 65(2) [Also in Group XXXII] In a tandem axle suspension for a vehicle (see Group XXXII) a radius rod 18a is pivotally connected to an axle by a ball joint comprising a stud 33 having a central ball portion 35 and semi-spherical bearing members 38, 39. The stud 33 is secured by bolts 45 to yoke arms 30, 30, which extend on either side of the radius rod, and are rigid with the axle. The stud 33 and bearing members 38, 39 are retained in a bore 43 by the bearing members 38, 39 being located in a further bore formed axially in the end of the radius rod 18a and at right angles to the bore 43, and retained by a screw plug 45 against the action of a coiled spring 40. The effective lengths of the radius rod 18a may be adjusted by the insertion of shims 41 between the bearing member 38 and the coiled spring 40. The plug 45 is retained by a cotter pin, Fig. 5 (not shown), and carries an eccentrically disposed grease nipple 45c, which connects with a grease reservoir 45a, and a lubricant groove 36 in the ball portion 35 of the stud 33. |
