Automobile clutch driven piece

The invention discloses an automobile clutch driven piece which comprises a driven piece body, wherein a long groove is formed in the driven piece; the side of the long groove is formed by non-tangentconnection of a first straight side, a second straight side and an arc-shaped side; two ends of the arc-shaped side are respectively connected with ends in a same direction, of the first straight side and the second straight side; and the diameter of the arc-shaped side is greater than the distance between the first straight side and the second straight side. By adopting the automobile clutch driven piece, the stress and the weight of the driven piece self are reduced, a processing process is improved, in addition, the driven piece is high in strength and small in rotational inertia, torque can be reliably and effectively transmitted, and the operation performance of driving shifting can be improved by virtue of the characteristic of small rotational inertia of the driven piece. 本发明公开了种汽车离合器用从动片，包括从动片本体，从动片上设有长槽，
