摘要： An apparatus for controlling the brake of a vehicle, which easily brings the vehicle to a halt, or starts it, only by the action of the accelerator without operating the brake pedal. Brakes (4, 5) are applied when the vehicle speed detected by a speed detector (9) becomes smaller than a predetermined threshold value. The operation of the brakes (4, 5) is turned off when a load detected by a load detector (10) becomes larger than a load operated by a load computer (11, 14).

摘要： This invention relates to a clutch switching circuit which can be utilized suitably for a multi-stage static hydraulic mechanical nonstage transmission. If pressure regulating valves having good override characteristics are used, slip or breakage of a clutch will occur. Therefore, this invention provides a clutch switching circuit which provides communicating throttle passages (311, 321, 331, 341) in the valve body of the pressure regulating valves (211, 221, 231, 241) so that a working fluid flows towards the clutch when the valves are closed. When the clutch is switched, the working fluid flows in a quantity equivalent at least to the oil leakage flow quantity so that the slip or breakage of the clutch can be prevented while pressure regulating valves having good override characteristics are used. The invention provides also a clutch switching circuit wherein common oil passages (301, 302) leading to a plurality of clutches corresponding to the gears which are not adjacent to one another are provided, and the pressure regulating valves (411, 421) and pressure reducing valves (412, 422) used commonly for a plurality of gears are installed in the common oil passages. Thus, the invention halves the number of valves of prior art apparatuses and simplifies the circuit construction.
摘要翻译：本发明涉及一种可以适用于多级静态液压机械非级变速器的离合器开关电路。如果使用具有良好超驰特性的压力调节阀，则会发生离合器的滑动或断裂。因此，本发明提供了一种离合器切换电路，其在压力调节阀（211,221,231,241）的阀体中提供连通节流通道（311,321,331,341），使得工作流体朝离合器流动当阀门关闭时。当切换离合器时，工作流体的流量至少等于漏油量，从而在使用具有良好超越特性的压力调节阀的情况下可以防止离合器的滑动或断裂。本发明还提供了一种离合器切换电路，其中设置有通向与彼此不相邻的齿轮相对应的多个离合器的通用油路（301,302），并且压力调节阀（411,421）和减压通常用于多个齿轮的阀（412,422）安装在公共油路中。因此，本发明将现有技术装置的阀门数量减半，并简化了电路结构。

摘要： A control device in a hydrostatic-mechanical transmitting machine constructed such that, to be driven through an input shaft coupled to a power source, a mechanical transmitting section and a hydrostatic transmitting section in which an angle of a discharge flowrate setting swash-plate of at least one of a pump and a motor is variable, are provided, and a differential section for coupling an output shaft to both the mechanical transmitting section and the hydrostatic transmitting section are provided for driving. An object of the invention is to cause the number of revolutions (nE) of the power source to quickly follow a target number of revolutions (NE) in accordance with changes in a throttle position (X). A target motor speed ratio (Em) involving a ratio (em) of the number of revolutions (nm) of the motor in the hydrostatic transmitting section to the number of revolutions (nE) of the power source is set based on the throttle position (X), and a control value (A), a sum of a feedforward value (KEm; where K: feedforward coefficient) being porportional to a target motor speed ratio (Em) and both a proportional element and an integrating element of a deviation (=Em-em) between an actual motor speed ration (em) and a target motor speed ratio (Em), is determined, whereby an angle of the discharge flowrate setting swash-plate is controlled.

摘要： A mechanical-hydraulic type transmission for crawler type vehicles which has a small size in the width direction orthogonal to input/output shaft and enables a combination with an existent crawler steering device to be selected arbitrarily. In the transmission, three parts divided longitudinally, i.e., a power input shaft (1) being directly in connection with a prime mover, an intermediate shaft (9) and an output shaft (19) are aligned. Planetary gears (5, 6) for forward and reverse rotation, having clutches (7, 8) on their peripheries respectively, are mounted on the power input shaft (1) connected to a variable capacity hydraulic pump (2). A plurality of planetary gear trains (11, 12), having clutch means (10, 13, 14) on their peripheries respectively, and a planetary differential gear (15) are mounted on the intermediate shaft (9). The output side of a variable capacity hydraulic motor unit (20) driven by the hydraulic pump (2), and the output shaft (19) are together in connection with the planetary differential gear (15).
