摘要： PURPOSE:To prevent both durability and efficiency-as-a-whole of a continuously variable transmission mechanism from being worsened, by temporarily elevating the line pressure, compared with the normal time, when the change gear is suddenly switched to the up-shift side. CONSTITUTION:A V-belt 32 is wound round both a driving pulley 24 and a driven pulley 34, in both of which the distance between the V-shaped grooves is variable in accordance with the oil pressure in a pulley cylinder chamber, so that the power can be transfered. When the change gear is suddenly switched to the up-shift side, the line pressure becomes higher than usual. As a result, a sufficient force acts on the V-belt. Therefore, in spite of large moment of inertia of the pulley, it is possible that the speed change in the direction of up-shift can be carried out without causing a slip to the V-belt. The elevation of the line pressure is a temporary phenomenon, although it is necessary for a sudden speed-change. Therefore, the line pressure returns to a normal state at the completion of the speed change. Thus, the trouble, which is caused by constantly outputting the oil pressure higher than necessary, can be prevented from occurring.

摘要： PURPOSE:To reduce space and decrease a load in a speed change motor, by separating a rod, actuated by the speed change motor, from a spool in a control pressure selector valve and pressing the spool as necessary. CONSTITUTION:A rod 182, actuated by a speed change motor 110, controls speed change ratio in no relation to a control pressure selector valve 108. If, for instance, the rod 182 is moved in the left direction by a predetermined distance, a lever 178 turns in the counterclockwise direction about a pin 183 serving as a supporting point moving a spool 174, connected with the lever 178, of a speed change control valve 106 in the left direction. In this way, the speed change ratio decreases by increasing a V-shaped pulley groove space. Thus a transmission, actuating the rod 182 being separated from a spool 983 in the control pressure selector valve 108, enables the dimension in the axial direction of the spool 983 to be reduced by decreasing its moving distance.

摘要： PURPOSE:To prevent the simultaneous occurrence of torque fluctuation of an engine and speed change of a transmission by providing a means for setting a predetermined time lag between the resumption of fuel supply and the release of down-shift condition. CONSTITUTION:When a fuel cut apparatus stops fuel supply to an engine and a down-shift means changes the speed of a transmission to the down-shift side, and when the resumption of fuel supply and the release of condition of speed change to the down-shift side are simultaneously commanded, a time lag setting means for setting a predetermined time lag between the resumption of fuel supply and the release of speed change condition to the down-shift side is provided. Thus, the torque variation of the engine and the speed change of the transmission are prevented from simultaneous occurrence.

摘要： PURPOSE:To eliminate an expensive electronic control device, etc. to greatly reduce the cost of a stepless speed change unit, by controlling the gear ratio of the stepless speed change unit with the use of a spool in a gear ratio determining valve which is in turn controlled by a hydraulic pressure corresponding to the load and rotational speed of an engine. CONSTITUTION:A link 178 from a gear shift control device is coupled to a gear ratio determining valve 110 in which the position of a spool 182 is determined by hydraulic pressure corresponding tothe load and rotational speed of an engine. Further, the gear ratio determining valve 110 shifts the position of the link 178 toward the increased gear ratio side when the hydraulic pressure corresponding to the load of the engine varies in the direction in which the load of the engine is increased. Further, the position of the link 178 is shifted toward the decreased gear ratio side when the hydraulic pressure corresponding to the rotational speed of the engine varies in the direction in which the rotational speed of the engine is increased. With this arrangement, the control of the stepless speed change unit may be satisfactory carried out with no use of an electronic control device, sensors, a variable speed motor, etc. which are expensive, thereby it is possible to greatly reduce the cost of the stepless speed change unit.
