The transmission shaft assembly comprises a spline, a transmission shaft and a cross joint unit, the spline, the transmission shaft and the cross joint unit are sequentially connected, the transmission shaft comprises an inner pipe and an outer pipe coaxially arranged on the outer side of the inner pipe in a sleeving mode, the inner pipe and the outer pipe form a containing space, the containing space is filled with noise reduction filler, and the cross joint unit is connected with the inner pipe in a sleeving mode. The whole containing space is filled with the noise reduction filler, and the inner pipe and/or the outer pipe are/is of a variable-diameter structure. The utility model provides a transmission shaft assembly and a vehicle and aims to solve the problems that vibration and noise generated in the working process of an automobile transmission system are large, and the effect is not ideal by arranging a vibration absorber between a transmission shaft and a transmission to relieve vibration and noise.
