摘要： The improved design of a closed toroidal circuit enabling various arrangements of bladed converter members or elements, with many of them standardized for the economical manufacture of various types of converters. The shapes of the outer and inner walls of the toroidal circuit in a radial converter plane are determined by a construction trapezoid and construction rectangle, respectively, that are specified by a system of rectangular coordinates and which have their corners rounded by arcs of specified radii. The outer and inner walls are tangent to an infinite number of circles the diameter of each of which is formulated in relation to the distance of the circle center from the converter axis and the maximum radius of the circuit.

摘要： A torque converter and a planetary gear set therefor, said planetary gear set having two sets of clutches wherein one element among a sun gear, a ring gear and a planetary carrier is connected directly to an input shaft, another element is connected directly to an impeller of said torque converter and the other element is connected to an output shaft via one of said clutches. A power absorption capability of the torque converter may be varied in two stages in order to meet separate demands for engine power which occur during various operating phases of vehicle operation.

摘要： A control system for an engine driven power train having a variable torque absorption transmission mechanism typically including a torque converter, in conjunction with a hydraulic control circuit for the implement of an excavating-loading vehicle such as a loader. The control circuit comprises lift and tilt cylinder means connected via respective control valves to a pump driven by the vehicle engine. The pump also communicates with the transmission mechanism via a variable pressure regulator valve which functions to condition the transmission mechanism for a relatively high torque absorption characteristic during vehicle propelling operation so that engine torque may be efficiently transmitted to the drive wheels of the vehicle. When either of the control valves is actuated for raising or tilting back the bucket of the loader, the transmission mechanism is automatically conditioned for a relatively low torque absorption characteristic so that the pump may be driven without any substantial decrease in engine speed.
摘要翻译：一种用于发动机驱动的动力传动系的控制系统，其具有通常包括变矩器的可变转矩吸收传动机构，结合用于诸如装载机的挖掘装载车辆的实施的液压控制回路。控制电路包括通过相应的控制阀连接到由车辆发动机驱动的泵的升降液压缸装置。泵还经由可变压力调节阀与传动机构连通，该可变压力调节阀用于在车辆推进操作期间调节传动机构以获得相对高的扭矩吸收特性，使得发动机转矩可以有效地传递到车辆的驱动轮。当任一个控制阀被致动以升高或倾斜装载机的铲斗时，传动机构被自动调节以获得相对较低的扭矩吸收特性，使得可以驱动泵而不会显着降低发动机转速。
