Abstract
The utility model relates to a transmission shaft for a test of an engine pedestal. The transmission shaft is characterized in that the transmission shaft comprises a pair of flange shafts (6, 10) and a damping rubber (7) connected between the flange shafts; one end of the flange shaft (6) is connected with a flywheel flange (3) of an engine; one end of the flange shaft (10) is connected with a constant-velocity inner rzeppa universal joint (11), and the other constant-velocity inner rzeppa universal joint (13) is connected with a dynamometer flange (14); a vehicle hollow half-axle (12) is connected between the two constant-velocity inner rzeppa universal joints. The transmission shaft has the advantages that due to the adoption of the inner rzeppa constant-velocity universal joints, the radial hop of the transmission shaft, which is brought to the median deviation, can be reduced; due to the adoption of the vulcanized damping rubber, the impact generated during the operation of the engine can be reduced.
