Abstract: In a multiratio transmission providing a low ratio drive and a plurality of higher ratio drives having a manual selector control to select the low ratio drive or automatic control of the plurality of higher automatically controlled ratio drives. On manual selection of automatic control, a plurality of automatic shift valves operate under the control of an output speed governor pressure and a torque demand pressure for automatic shifting between the low and high automatically controlled ratios in response to speed and torque demand. On manual selection of the lowest ratio drive, after the automatic control is in the lower or first automatic ratio drive, a selector valve pressure will be supplied by a low signal valve, if both the inverted modulator pressure is high, indicating less than 15% throttle advance and the governor pressure is low indicating low vehicle speed. The predetermined low throttle advance and low speed at which a manual shift to low may be made is independently controlled and adjusted by independently adjustable springs.
Abstract translation: 在提供低比率驱动的多速传动和具有手动选择器控制的多个较高比例的驱动器中,选择多个较高自动控制比率驱动器的低比率驱动或自动控制。 在手动选择自动控制时,多个自动换档阀在输出调速器压力和扭矩需求压力的控制下操作,用于响应于速度和扭矩需求在低和高自动控制的比率之间自动换档。 在手动选择最低比率驱动时,自动控制在较低或第一自动比率驱动中后,如果两个反相调节器压力高,则显示小于15%的选择阀压力将由低信号阀提供, 节气门推进,调速器压力低,表示车速低。 可以通过独立调节的弹簧来独立地控制和调节手动换档到低速的预定低油门前进和低速。
