Abstract

The invention relates to the technical field of vehicle driving shafts, and provides a transmission shaft structure. The transmission shaft structure comprises a bearing, a spline sleeve and a spline shaft, wherein a vibration reducing support device is arranged on an outer ring of the bearing, and can be fixedly supported on a vehicle body; the spline sleeve is assembled in the inner ring of the bearing through a spline structure; and the spline shaft is assembled in the spline sleeve through a key slot structure, and can axially extend. The transmission shaft structure prominently reduces or solves such vibration noise problems as unbalanced rotation caused by nonuniform mass distribution of the transmission shaft, is excellent in energy absorption and vibration isolation effects, and improves the NVH performance of a transmission system.

Description

technical field [0001] The invention relates to the technical field of vehicle transmission shafts, in particular to a transmission shaft structure and a transmission shaft with such a transmission shaft structure. Background technique [0002] As people's requirements for vehicle driving system and NVH performance are getting higher and higher, the performance design of various parts of the vehicle is also continuously improved. As is known, propshafts are essential components in vehicle powertrains. At present, with the increasing number of front-wheel drive and timely four-wheel drive or front-rear drive vehicles, the longitudinal transmission shaft has become one of the indispensable components in the process of torque transmission. [0003] In an existing vertical transmission shaft structure, that is, in the design of a transmission shaft with a shaft tube length greater than 1.5 m, the transmission shaft is provided with an intermediate support structure. In this ki...
