摘要： A steering shaft assembly has a tubular main body and a shaft, with a spring and a sleeve disposed at least partially therebetween. The shaft is disposed at least partially in the tubular main body and the sleeve is disposed at least partially between the spring and the main body. The sleeve acts to urge the spring into frictional contact with the shaft to impart an axial resistance force supporting the shaft against axial displacement in response to application of an axial force on the shaft less than the axial resistance force. The sleeve enables axial displacement of the shaft in response to application of an axial collapsing force exceeding the axial resistance force. In another construction of a steering shaft assembly, a shaft is disposed at least partially in the tubular main body and the spring is disposed at least partially in the tubular main body between the tubular main body and the shaft. The spring acts to impart a radial load between the shaft and the tubular main body. The spring has at least one undulation that provides for linear frictional contact between the spring and the shaft in a circumferential direction about the shaft to resist torsional rotation of the shaft relative to the tubular main body.
