Because of overheat and over wear, the distortion and invalidation will be produced easily in combining friction discs of wet clutch of heavy vehicle transmission system. So the paper studies the sliding friction force of a pair of steel and friction disc, calculates the heat flow density, obtains the heat exchange function with axial symmetry, and establishes the finite element model of temperature field. And then the transient heat field simulation is analyzed, and temperature field distribution curves of combining pairs are obtained. Thus the connection is found between time and temperature along radial and axial direction, and temperature field characteristics are obtained with touch press, relative speed, and sliding time.
