The invention discloses a straight ball base of a V-type track bar assembly. The straight ball base comprises a straight ball base body which is formed through forging and finish machining, and a spherical pin columnar through hole is formed in the center of the straight ball base body. A protruding ring used for stopping a spherical pin is machined in the inner end of one side of the columnar through hole of the straight ball base body. A groove used for embedding a retainer ring so as to position and fix the spherical pin is machined in the inner end of the other side of the columnar through hole of the straight ball base body. A cylindrical connecting end which is integrally formed in a circular arc transition manner is forged at the outer side wall end of the straight ball base body. A necking-down columnar connecting section is machined at the cylindrical connecting end and sleeved with a connecting pipe. The necking-down columnar connecting section and the connecting pipe are integrated in a friction welding mode. The thickness of the straight ball base body is greater than the diameter of the cylindrical connecting end. The outer circle wall surface of the straight ball base body is an inclined circular ring surface with the center being in an outwards protruding circular ring shape and the two ends being gradually retracted. The straight ball base of the V-type track bar assembly has the characteristics of being reasonable in structure composition, convenient to machine and manufacture, high in connecting fastness of a tubular bar body, high in manufacturing efficiency, safe and reliable to use and the like.
