    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 power plant for a front engine front drive type automotive vehicle. The power plant is comprised of a forward and transversely mounted engine having a cylinder block with which a transaxle is joined through a plurality of joining points with bolts. The final drive unit of the transaxle includes a differential and projects laterally from the transmission. The center axis of the differential is offset low relative to the center axis of a crankshaft of the engine. The engine is disposed to incline rearward relative to the vehicle such that the inclination of the bottom face of the cylinder block relative to a horizontal plane is larger than the inclination of a line connecting the differential center axis and the differential center axis relative to the horizontal plane, thereby rigidly supporting the final drive unit.

    摘要： In a method of manufacturing a rack for a variable ratio rack and pinion steering gear, having a preforming process for preparing a rack blank having a plurality of teeth which are formed to a shape corresponding approximately to the shape desired in the finished rack and a finishing process for converting the teeth to the finished shape by cold forming in a die having a shape which is the exact counterpart of the finished shape, the preformed rack teeth are shaped to have top lands which are level with those in the finished shape and bottom lands that are deeper than those of same. The rack teeth in the preformed shape are all wider at the top areas than in the finished shape, and the ratio of the widths at the root areas of the rack teeth in the preformed shape to those in the finished shape varies in proportion to the variation of the steering ratio such that a rack tooth for a higher steering ratio is given the above-mentioned ratio that is larger.

    摘要： A reduction gear device with a differential gear mechanism 4 for an electric vehicle, has a planetary gear type reduction gear mechanism 3 for transmitting a power from an electric motor 2 to right and left wheels 6, 6 of the vehicle through the differential gear mechanism 4. The reduction gear mechanism 3 is contained in a casing 1, while either of output shafts 4a, 4b of the differential gear mechanism 4 penetrates an output shaft 2c of the electric motor 2. The reduction gear mechanism 3 comprises a plural of complex pinions P each formed by integrating a first pinion P1 and a second pinion P2 having a less number of teeth than that of the first pinion P1, a planetary carrier C3 connected to the output shaft 2c of the electric motor 2 and rotatably supporting each of the complex pinions P at certain positions on a common circle, a first ring gear R1 fixed onto the casing 1 and engaged with the first pinion P1 of each of the complex pinions P, and a second ring gear R2 engaged with the second pinion P2 of each of the complex pinions P and serving to transmit the power from the electric motor 2 to the differential gear mechanism 4. When utilizing a small size motor of high speed type as the electric motor 2, the reduction gear device can reduce a size of the device and simplify a construction of the device, while increasing a reduction ratio thereof.
