The extrusion-formed INPUT input shaft for the automobile comprises a hollow pipe, a pipe expanding structure is integrally formed at one end of the hollow pipe, a connector is integrally formed on the pipe expanding structure, an outer spline is integrally formed on the outer wall of the other end of the hollow pipe, and an inner spline is integrally formed on the outer wall of the other end of the hollow pipe. Spline teeth are integrally formed in the position, located on the outer side of the outer spline, of the end of the hollow pipe, a clamping groove is formed in the connector, a reinforced protective shell is integrally formed on the outer surface of the hollow pipe, and an inner protective piece is integrally formed on the surface of the inner wall of the hollow pipe. According to the extrusion-formed INPUT input shaft for the automobile and the preparation method of the extrusion-formed INPUT input shaft, the hollow pipe cold extrusion forming process is adopted, the product size precision is higher than the precision of a forged product, meanwhile, the product weight is greatly reduced compared with that of solid forging, the cost is also reduced, and meanwhile the productivity efficiency of the cold extrusion process is far higher than that of the forged product.
