摘要： In order to prevent sudden fluctuations in the supply of hydraulic fluid fed to a power steering or like servo mechanism and to enable the downshifting of a transmission used to drive the pump and an ancillary device such as an alternator, at speeds suited to the specifications of the alternator, a "flow-down" valve induces first and second flow reductions which are separated by an engine speed range which enables the higher downshift speed to be selected at an engine speed suited to the specifications of the alternator. The first flow reduction or flow-down occurs within a relatively narrow engine speed range. This facilitates the above mentioned selection and additionally enables a change from a high power steering assist at low speed to an intermediate one. The second "flow-down" enables a more gradual change from the intermediate assist to a low level one suitable for high speed driving. In the embodiment of the invention, the engine speeds at which the transmission is downshifted are selected to correspond to the pump speed just before and just after the first flow reduction occurs in the upshift and downshift conditions of the transmission, respectively. Shifting of the transmission due to sharp changes in load is inhibited when the engine is operating between the first and second speeds.
摘要翻译： 为了防止供应到动力转向或类似伺服机构的液压流体的供应的突然波动，并且使得用于驱动泵的变速器和诸如交流发电机的辅助装置的换档速度适合于 交流发电机，“下降”阀引起第一和第二流量减小，其通过发动机转速范围分开，这使得能够以适合于交流发电机规格的发动机转速来选择较高的降档速度。 第一流量减少或流量下降发生在较窄的发动机转速范围内。 这有助于上述选择，并且还能够从低速度的高功率转向辅助转变为中间转向辅助。 第二个“下降”使得能够从中间辅助向下一个适应于高速驾驶的较低水平的逐渐变化。 在本发明的实施例中，变速器降档的发动机速度被选择为分别对应于在变速器的升档和降档条件下发生第一次流量减少之前和之后的泵速。 当发动机在第一和第二速度之间操作时，由于负载的急剧变化而导致的变速器的变速被抑制。

摘要： A torque sensor for use in automotive transmissions includes first and second sets of grooves define first and second sets of elongate projections which are respectively subject to compression and elongation when the shaft in which they are defined, is subject to torque. Two yoked coils which are excited with an alternating current, are each disposed close to a set of projections. The compression and elongation of the projections changes the amount of magnetic flux which flows along the projections and therefore the inductance of the coils. The coils form part of a bridge circuit which is sensitive to the change in inductance in a manner which enables the amount of torque to be measured.

摘要： A constant velocity universal joint comprises an outer joint element having grooves on its spherical inner surface. An inner joint element is positioned within the outer joint element and is provided with grooves on its spherical outer surface to form pairs of opposed grooves with the grooves on the outer joint element. A ball is positioned in every pair of opposed grooves and a cage disposed between the two joint elements retains the balls in a plane perpendicular to the axis of the cage. The cage is guided within the outer joint element by a spherical surface on the outer face of the cage and is guided with respect to the inner joint element by a spherical surface on the inner face of the cage. To facilitate assembly in the joint without weakening structural strength of the cage, the cage is provided with transverse notches or grooves in two diagonal positions. Each groove is formed at a ball aperture and has a width and a depth so as to be capable of receiving a ridge between adjacent grooves on the outer joint element.
