发明名称 REDUCING DEVICE FOR SPEED CHANGE SHOCK OF AUTOMATIC SPEED CHANGE GEAR
摘要 PURPOSE:To reduce a shock caused by speed change by closing a response valve to torque fluctuation in the case of quick fluctuation in shaft torque. CONSTITUTION:A torque pressure PT corresponding to the shaft torque of an automatic speed change gear is directly supplied to the chamber 20d of a response valve 20 to torque fluctuation through a circuit 21, and also supplied to a chamber 20e from a circuit 22 through a orifice 28 with an accumulator 24 being at work. In this case, pressure in the chamber 20e becomes lower than that in the chamber 20d on account of the existence of the first delaying elements 23, 24 as the torque pressure rises more speedily, or the shaft torque increases more quickly. Accordingly the valve 20 moves from a position shown in the drawing to the left in the case of a quick increase in the shaft torque to cut off a bypass circuit 19. Thus working oil pressure PO is supplied to a frictional element 15 only through the orifice 17, and a shock caused by speed change can be reduced.
