摘要： Line pressure is adjusted by one valve for supplying the pressure to control the engagement of a clutch in normal and abnormal operating conditions. In the normal operating condition, the valve control pressure which is controlled by a starting clutch control valve 41 is used for the control of a clutch pressure control valve 42, so the line pressure from a line 61b is adjusted to control the engagement of the starting clutch 5. If there is a breakdown, two electrically controlled valves 41 and 45 are turned off, and the line pressure is applied through another line 64. As a result, the spool of a shift restriction valve 43 is shifted to the left, so the hydraulic oil is supplied to a pitot flange 51. In this condition, the pressure (correspondent pressure) which corresponds to the rotational speed of the engine is supplied as a signal pressure from a pitot pipe 53 through lines 66 and 67 to the shift restriction valve 43. This hydraulic controller adjusts the line pressure in the line 61b by using this correspondent pressure for controlling the engagement of the starting clutch 5.

摘要： A lubrication pressure controller comprises a lubrication pressure regulating valve 41, which is provided in a lubrication oil passage 36 directing hydraulic oil to lubricated parts, and a cooler pressure regulating valve 42, which is provided in a discharge oil passage 51b of the lubrication pressure regulating valve 41. The lubrication pressure regulating valve 41 adjusts the pressure in the lubrication oil passage 36, and the cooler pressure regulating valve 42 adjusts the pressure supplied to an oil cooler 55. The hydraulic oil discharged from the cooler pressure regulating valve 42 is returned through a recirculation line 52 to a suction oil passage 31 of a pump. In this construction, an adequate supply of lubrication oil is maintained even if one of the valves experiences locking of a valve spool on an open side. Moreover, by providing signal pressure generating means 60, which applies a signal pressure to these two valves in correspondence with a driving condition, the lubrication pressure controller can be set to acquire a desired balance in the lubrication, cooling and recirculation for the hydraulic oil in response to a driving condition.

摘要： Leak oil from a regulator 24 for regulating the pressure of oil supplied to a lubricating system (the lubricating pressure) is supplied to an oil cooler 23. An electromagnetic valve 25 is connected to a pressure controlling and regulating oil chamber 24a of the regulator 24 so that the lubricating pressure can be controlled to be increased or decreased. The lubricating pressure is decreased while an engine is running in a low load state during a high-speed running to thereby increase the volume of oil to be supplied to the oil cooler 23.

摘要： In a chamber R1 which accommodates a transmission device comprising a drive pulley 8, a driven pulley 9 and a belt 10, a cover 51 is provided to cover the lower peripheral portion of the drive pulley 8 along the periphery. The drive pulley is positioned below the driven pulley, and raised portions 52 which are used for the detection of the rotational speed of the drive pulley are provided on the periphery of the drive pulley. The end surface 51bs of the cover facing the inner wall 54 of the pulley chamber is positioned away from the inner wall with a clearance V therebetween. In a vehicular transmission which is constructed in this arrangement, the amount of lubrication oil that flows near to the periphery of the pulley which is positioned lower is comparatively small. Thus, this arrangement restricts agitation of the lubrication oil, which may be caused by the raised portions of the rotating pulley. Therefore, loss in the rotation of the pulley and oxidation and degradation of the lubrication oil are effectively prevented.

摘要： An inlet opening 41 for a discharge oil passage 76 is provided in a chamber R1 which accommodates a transmission device comprising a drive pulley 8, a driven pulley 9 and a belt 10. This inlet opening is positioned at a location where the inner wall of the chamber is met by a line drawn tangentially to the pitch circle of the drive pulley whose pitch radius is at a maximum and to that of the driven pulley whose pitch radius is at a minimum . This inlet opening 41 for the discharge oil passage 76 is positioned also at a location where the inner wall is met by a line drawn on the upper side of the pulleys tangent to the peripheries of the drive and driven pulleys 8 and 9. By providing an inlet opening for the discharge oil passage in this arrangement, the lubrication oil which is being thrown from the belt 10 is efficiently discharged through the inlet opening 41 directly to the outside of the chamber. This lubrication oil is then led through the discharge oil passage 76 to the oil pan 26. As a result, while the amount of the oil in the oil pan located below the chamber is maintained at a certain amount, the amount of the lubrication oil which flows down along the inner walls of the chamber is kept to a substantially small amount. In this way, the rotational loss which may be caused from agitation of the oil by the drive pulley is substantially reduced.

摘要： In a power transmission system in a vehicle including a continuously variable gear path and a multi-stage gear path, a difference between gear ratios at the start of forward travel and at the start of backward travel is minimized, while using a single-pinion type planetary gear mechanism. The continuously variable gear path includes a forward/backward travel switching mechanism comprising a single-pinion type planetary gear mechanism, and a belt-type continuously variable transmission. A multi-stage gear path comprising gears is set at a gear ratio closer to a LOW side from that of the belt-type continuously variable transmission. Thus, when the forward traveling and the backward traveling are switched over from one to another, it is unnecessary to suddenly change the gear ratio of the belt-type continuously variable transmission, which can contribute to an improvement in durability of belt-type continuously variable transmission.
