摘要： A suspension for a steerable driving wheel in a vehicle, in which a wheel supported by a wheel carrier rotatable around a steering axis is driven by a drive shaft and braked by a brake caliper, includes a hub and a brake disk. The hub has a supported portion rotatably supported by the wheel carrier through a bearing and is unrotatably connected to the drive shaft. The hub attaches the wheel to a portion located more laterally outward of a vehicle body than the supported portion. On the other hand, the brake disk for generating a braking force in cooperation with the brake caliper is provided on the hub and disposed more laterally inward of the vehicle body than said supported portion.

摘要： A constant velocity universal joint wherein its outer race has a larger radius of curvature than its inner race at the transverse sectional surface of the ball rolling groove at the point of contact between the ball and the ball rolling groove. Concave and convex surface portions of a ball rolling groove have a characteristic such that when the inner and outer races have the same radius of curvature at the transverse sectional surface of the ball rolling groove, the contact stress of the ball rolling groove of the outer race becomes lower than that of the inner race. By varying the radius of curvature on the transverse sectional surface of the ball rolling groove of the outer race from that of the inner race to render the contact stresses of the two grooves equal to each other, it is possible to facilitate working of the grooves and yet to achieve the same degree of precision finishes as has hitherto been achieved.
摘要翻译：一种等速万向接头，其中，在球和球滚动槽之间的接触点处，其外圈在球滚动槽的横截面处具有比其内圈更大的曲率半径。滚珠滚动槽的凹凸面部具有这样的特性，即当内圈和外圈在滚珠槽的横截面具有相同的曲率半径时，外圈的滚珠滚动槽的接触应力变得比内圈的低。通过使外圈的滚珠滚动槽的横截面上的曲率半径与内圈的曲率半径相等，使两槽的接触应力相等，能够有利于槽的加工，尚未达到迄今为止所完成的相同程度的精加工。

摘要： A broaching method for finishing an outer peripheral surface of a resin layer of a resin-coated lobe-type rotor for a rotary fluid machine of a Roots type, which includes the steps of forming, with a leading grooving cutter, at least one chip-breaker groove in the outer peripheral surface of the resin layer, such that the chip-breaker groove extends in a broaching direction parallel to an axis of rotation of the rotor. The method further includes the steps of finishing at least a portion of the outer peripheral surface of the resin layer with a trailing finish cutter having a cutting edge contour corresponding to the portion of the outer peripheral surface of the resin layer, which is finished by the finish cutter after the chip-breaker groove is formed therein by the grooving cutter. A composite broach or formed broach having the grooving and finish cutters is fed such that the grooving cutter leads the finish cutter in the broaching direction.

摘要： A hydraulic power steering system includes a pump, a flow control valve, and a bypass control valve. The flow control valve responds to a pressure drop across a metering orifice disposed in a fluid supply passage so as to control the flow rate of operational fluid by bypassing part of the operational fluid to a reservoir. A spring chamber of the flow control valve is connected to the supply passage through a control orifice. The bypass control valve is disposed between the spring chamber and the reservoir so as to increase the amount of bypassed fluid by controlling the pressure in the spring chamber. The bypass control valve has a control spool, a load pressure introduction port connected to the upstream side of the control orifice for leading the load pressure to a first end of the control spool and a pilot port connected to the downstream side of the control orifice for leading the pressure in the spring chamber of the flow control valve to a second end of the control spool. Moreover, a pressure receiving area of the second end of the control spool is smaller than that of the first end of the control spool. Accordingly, a spring having a small spring constant can be used in the bypass control valve, even when the control spool is controlled within a short stroke.
摘要翻译：液压动力转向系统包括泵，流量控制阀和旁通控制阀。流量控制阀响应设置在流体供应通道中的计量孔的压降，以便通过将部分操作流体旁路到储存器来控制操作流体的流速。流量控制阀的弹簧室通过控制孔连接到供给通道。旁通控制阀设置在弹簧室和储存器之间，以通过控制弹簧室中的压力来增加旁路流体的量。旁通控制阀具有控制阀芯，连接到控制孔的上游侧的负载压力引入口，用于将负载压力引导到控制阀芯的第一端，以及连接到控制孔的下游侧的先导端口，将流量控制阀的弹簧室中的压力引导到控制阀芯的第二端。此外，控制阀芯的第二端的受压面积小于控制阀芯的第一端的受压面积。因此，即使控制阀芯在短行程内被控制，也可以在旁通控制阀中使用弹簧常数小的弹簧。
