    摘要： In a steering mechanism wherein the turning angle of a steering wheel is transmitted to a wheel via a link mechanism employing a tire rod (3) and a knuckle arm (4), the link mechanism and the wheel (1) are coupled by a multiplying gear (2). Individual drive mechanisms are mounted independently on each wheel, and each wheel is driven independently to enable front-wheel independent drive, rear-wheel independent drive and four-wheel independent drive. Drive of an inner rear wheel is changed over at a steering angle in the vicinity of 90.degree. to effect control of steering. A steering angle multiplied twofold or more can be obtained in simple fashion via the multiplying gear (2) even for a steering angle of about 45.degree. using the conventional link mechanism. In the drive of each wheel, drive of the inner rear wheel is halted in the vicinity of the 90.degree. steering angle, so that locking of the inner front wheel can be avoided. Further, only the inner rear wheel is driven in the reverse direction when a large steering angle is obtained. This makes smooth vehicle travel possible even at large steering angles.

    摘要： A failsafe hydraulic circuit designed to avoid simultaneous engagement of two friction engagement elements (e.g., clutches, brakes, etc.) incorporated in a speed change apparatus of a motor vehicle or the like. If a first failsafe valve is in the open position state and a first engaging pressure is supplied to a first hydraulic servo via the first failsafe valve, the first engaging pressure is also input to a first oil pressure switch via a second failsafe valve being in the closed position state. Therefore, using the first oil pressure switch, it can be detected that the first engaging pressure is supplied to the first hydraulic servo. Furthermore, if the first engaging pressure is, for example, greater than the set pressure of the first oil pressure switch, this situation can also be detected. Such detections provide confirmation of normal operation of the first failsafe valve and the second failsafe valve.

    摘要翻译： 一种故障安全液压回路，设计用于避免同时接合装在机动车辆等的变速装置中的两个摩擦接合元件（例如离合器，制动器等）。 如果第一故障保护阀处于打开位置状态，并且第一接合压力经​​由第一故障保护阀供应到第一液压伺服系统，则第一接合压力也经由第二故障保护阀输入到第一油压开关 关闭位置状态。 因此，使用第一油压开关，可以检测到第一接合压力被供给到第一液压伺服机构。 此外，如果第一接合压力例如大于第一油压开关的设定压力，则也可以检测到这种情况。 这种检测提供对第一故障安全阀和第二故障保护阀的正常操作的确认。
