摘要： A power steering device for a vehicle includes an input shaft (1) linked to a steering wheel, an output shaft (2) linked to a vehicle wheel, a torsion bar (3) that connects the input shaft (1) to the output shaft (2), and a cylindrical member (13) supported by a housing (12) that is fastened to a vehicle body. The input shaft (1) includes a first input shaft (4) that is inserted into the cylindrical member (13), supported rotatably by the cylindrical member (13), and linked to the steering wheel, and a second input shaft (5) that connects the first input shaft (4) to the torsion bar (3). A connection portion between the first input shaft (4) and the second input shaft (5) is constituted such that a rotation of the first input shaft (4) is transmitted to the second input shaft (5) and the first input shaft (4) is free to move in an axial direction relative to the second input shaft (5).

摘要： A forklift has a frame and a rear axle, which is pivotally joined to the frame about a center pivot axis. Front and rear supporting members support the frame on the axle. A damper is located between the frame and the axle. The damper has an upper end connected to the frame and a lower end connected to the axle. A bracket for joining the upper end of the damper to the frame is located no further forward than the front end of the front support member and no further rearward than the rear support member. This structure suppresses torsion and bending force applied to the damper.

摘要： A structure for supporting a hydraulic cylinder that controls pivoting of a rear axle in a forklift. The rear axle is supported pivotally to the body. The hydraulic cylinder connects the rear axle to the body. Two hydraulic oil chambers are defined in the hydraulic cylinder. Movement of hydraulic oil between the oil chambers is selectively permitted and prohibited to selectively permit and prohibit pivoting of the rear axle. The body includes a pair of side frame members located on the sides of the body and a pair of cross frame members connected to the side frame members. The rear axle is located under the cross frame members. One end of the hydraulic cylinder is pivotally connected to the cross frame members by an upper joint. An upper pin, which is part of the upper joint, is directly supported by the cross frame members. Accordingly, an exclusive bracket for coupling the hydraulic cylinder to the body is not necessary. This simplifies the structure for coupling the hydraulic cylinder to the body.

摘要翻译： 一种用于支撑液压缸的结构，其控制叉车中的后桥的枢转。 后轴可枢转地支撑在车身上。 液压缸将后轴连接到车身。 在液压缸中定义了两个液压油室。 选择性地允许油室之间的液压油的移动，并禁止选择性地允许和禁止后轴的枢转。 主体包括位于主体侧面的一对侧框架构件和连接到侧框架构件的一对横框架构件。 后轴位于十字框架下方。 液压缸的一端通过上接头枢转地连接到十字框架构件。 作为上接头的一部分的上销由十字架构件直接支撑。 因此，不需要用于将液压缸联接到主体的专用支架。 这简化了将液压缸联接到车身上的结构。

摘要： The improved small current detector circuit and locator device each include a first and a second capacitor, a pulse drive circuit which drives one terminal of each capacitor by a pulse signal and charges and discharges the capacitors in synchronism with the rise and fall of the applied pulse so as to generate a first and a second detection signal at the other terminal of each capacitor. A current generator circuit receives the first and second detection signals and generates a current representing the difference between the levels of said signals. An integrator circuit integrates the output current from the current generator circuit. At least one of the first capacitor or second capacitor is provided in a detection portion of the detector circuit or locator device.
