Trailing arm joint structure.

摘要

A trailing arm joint structure includes a knuckle (20) for supporting a wheel and a substantially plate-like trailing arm (10) lying in a vertical plane and having a front end adapted to be pivotally coupled to a vehicle frame and a rear end fastened by bolts to the knuckle (20). The knuckle (20) has a front bifurcated portion (21) composed of first upper and lower joint fingers (22, 22) extending forwardly and spaced vertically from each other, the knuckle having a link joint (25) positioned between the first upper and lower joint fingers (22, 22). The rear end of the trailing arm (10) has a rear bifurcated portion (11) composed of second upper and lower joint fingers (12, 12) extending rearwardly and spaced vertically from each other, the front and rear bifurcated portions (11, 21) being held against each other with said first and second upper and lower joint fingers (12, 12: 22, 22) being fastened together.
