Abstract: A magnetic load sensor unit is provided which can detect a load with a minute movement of its part, and which is durable and less likely to be influenced by temperature. The sensor unit includes a flange member (1) deflectable when an axial load is applied, a support member (2) supporting the flange member (1), a magnetic target (3) which generates a magnetic field, and a magnetic sensor (4) for detecting the magnetic field generated by the magnetic target (3). The magnetic target (3) and the magnetic sensor (4) are fixed to the flange member (1) and the support member (2), respectively, such that when the flange member (1) is deflected, the magnetic target (3) and the magnetic sensor (4) move relative to each other, whereby magnitude of the load can be detected based on the magnetic field detected by the magnetic sensor (4).

Abstract: An electric linear motion actuator includes planetary rollers mounted between the radially inner surface of an outer ring member and the radially outer surface of a rotary shaft, and a carrier rotatable about the rotary shaft and including radially movable roller shafts rotatably supporting the respective planetary rollers. Elastic rings each having circumferentially separate ends are each wrapped around the roller shafts to radially inwardly bias the roller shafts, thereby bringing the respective planetary rollers into elastic contact with the radially outer surface of the rotary shaft. Each elastic ring is prevented from rotating relative to the roller shafts, thereby preventing one of the roller shafts from being axially aligned with the gap between the circumferential separate ends, causing the elastic ring to be radially compressed and thus making it impossible for the elastic rings to radially bias the roller shafts.

Abstract: A rotation transmission device is mounted in a drive train of a four-wheel drive vehicle to selectively distribute driving force to selected vehicle wheels according to the travel condition of the vehicle. This device includes an outer ring and an input shaft. A cylindrical face is formed on one of the opposed surfaces of the outer ring and the input shaft, while cam faces are formed on the other opposed surface to define a wedge-shaped space between the cylindrical face and each cam face. Rollers are mounted in pockets formed in a retainer mounted between the input shaft and the outer ring. An electromagnetic clutch is coupled to the retainer. A switch spring is mounted between the retainer and the input shaft. A two-way clutch is provided between the outer ring and the input shaft. A control unit controls the two-way clutch by adjusting the amount of current fed through a coil of the electromagnetic clutch according to the travel condition of the vehicle, thus selectively distributing driving force to selected vehicle wheels. A method of controlling the rotation transmission device is also proposed. Also, another transmission device is proposed which is mounted in the transfer of a vehicle.

Abstract: A control system for a 4WD vehicle has a rotation transmission device which can prevent a two-way clutch of the rotation transmission device from vibrating by repeatedly locking and unlocking when the vehicle is started in a cold environment. The rotation transmission device is mounted in the transfer. The transfer is provided with a temperature sensor for measuring the temperature of oil in the transfer. If the oil temperature as measured by the temperature sensor is below a predetermined value when the vehicle is started with the drive mode set at the 2WD position, the hub clutches are engaged to reduce the idling speed of the two-way clutch and thus to prevent the two-way clutch from locking.

Abstract: An auto-tensioner for a belt has a cylindrical body having a bottom. A nut formed with female threads on its inner periphery and having a rod integrally formed at one end is slidably mounted in the body. A bolt is mounted in the body so that its male threads will engage the female threads on the nut. A belt loading spring is mounted between the nut and the bottom of the body to urge the nut in such a direction as to increase the tension to the belt. A bolt turning spring is mounted between the nut and the bolt to urge and turn the bolt in such a direction as to be pressed against the bottom of the body or in a direction away from the nut. Thus the nut and the bolt are moved either toward or away from each other according to the load from the belt which acts on the rod so as to automatically adjust the tension to the belt.

Abstract: The magnetic attraction force of an electromagnetic coil in an electromagnetic clutch is increased in a limited installation space, thereby improving reliability of operation. The dimensions of a field core housing the electromagnetic coil and a rotor are optimized to increase the magnetic attraction force. The thicknesses of cylindrical portions on the inner-diameter side of the field core and the rotor have larger thicknesses than those of cylindrical portions on its outer-diameter side so that the sectional areas of both cylindrical portions will be equal to each other. Also, a rotation transmission device provided with an electromagnetic clutch is proposed which can avoid deterioration of its sealing property and damage to its bearing and avoid cost increase.
