The invention discloses a vehicle suspension assembly, a composite structure buffer device and a vehicle. The vehicle suspension assembly comprises an integral rear axle and a buffer device. The integral rear axle is arranged behind a body longitudinal beam; the integral rear axle and the body longitudinal beam are arranged at an interval in the vertical direction, and the distance between the body longitudinal beam and the integral rear axle is adjustable; the buffer device is arranged on the body longitudinal beam, and the lower end surface of the buffer device is spaced with the integral rear axle; the buffer device comprises a polyurethane buffer block and a flexible limit block; the horizontal height of the lower end surface of the polyurethane buffer block is lower than that of the lower end surface of the flexible limit block, and the horizontal height of the lower end surface of the polyurethane buffer block is higher than that of the lower end surface of the flexible limit block in maximum deformation. The vehicle suspension assembly has enough compression stroke, thus a suspension has enough jumping stroke, the buffer time is extended, so that the buffer device has smaller and gentle stiffness change during contact, and riding comfort is guaranteed.
