To efficiently assemble or manufacture a belt by fastening a plurality of elements in a circular manner using a ring. A belt assembling device is adapted to assemble a belt by fastening a plurality of plate-like elements juxtaposed in a same orientation and in a circular manner using a ring. The belt assembling device includes a holding member. The holding member holds the ring to which the elements are attached sequentially, in a manner to keep a curvature radius of the ring partially larger than that of the remaining portion. Therefore, the portion of the ring at which the curvature radius is thus kept larger can be twisted and deformed easily so that the element can be attached to the ring at the portion.

A power transmission unit for a vehicle including a first clutch device that selectively allows a torque transmitting route from an input shaft to an output shaft via a first gear train to transmit torque therethrough, a dog clutch that switches the torque transmitting route from the input shaft to the output shaft between a continuously variable speed change route in which the torque is transmitted through a continuously variable transmission and a reverse route in which the torque is transmitted through a second gear train, and a second clutch device that connects and disconnects both of the continuously variable speed change route and the reverse route to/from at least any one of the input shaft and the output shaft.

摘要:
A power transmission unit for a vehicle is provided. In the power transmission unit, torque is transmitted between an input shaft and an output shaft through a continuously variable transmission and a gear train having an intermediate shaft. The continuously variable transmission adapted to alter a speed ratio continuously is disposed between the input shaft to which a torque of a prime mover is inputted and the output shaft that outputs the torque. The gear train is adapted to establish a speed ratio that cannot be established by the continuously variable transmission, and arranged at a different site from positions of the input shaft and the output shaft. The power transmission unit comprises: a torque reversing device that is adapted to perform a differential action among an input element, an output element and a reaction element adapted to rotate the input element and the output element in opposite directions when rotation thereof is halted, and that is disposed coaxially with the output shaft or the intermediate shaft; a first clutch device that connects at least any of two rotary elements of the torque reversing device; and a brake device that halts rotation of the reaction element. The input shaft is connected with the output shaft through the continuously variable transmission, and a second clutch device is disposed on a torque transmitting route from the input shaft to the output shaft via the continuously variable transmission to allow and interrupt torque transmission therethrough. The input shaft is connected with the output shaft through the gear train and the torque reversing device.

A power transmission unit for a vehicle is provided. In the power transmission unit, a continuously variable transmission to alter a speed ratio continuously is disposed between an input shaft to which a torque of a prime mover is inputted and an output shaft rotated by the torque transmitted from the input shaft. A first gear train that transmits the torque to propel the vehicle in the forward direction is arranged parallel to a second gear train that transmits the torque to propelling the vehicle backwardly. The power transmission unit is comprised of: a first clutch device that selectively allows a torque transmitting route from the input shaft to the output shaft via the first gear train to transmit the torque therethrough; a dog clutch that switches the torque transmitting route from the input shaft to the output shaft between a continuously variable speed change route in which the torque is transmitted through the continuously variable transmission and a reverse route in which the torque is transmitted through the second gear train; and a second clutch device that connects and disconnects both of the continuously variable speed change route and the reverse route to/from at least any one of the input shaft and the output shaft.

An processing apparatus comprises a laser oscillator, an overall control device which controls an operation of the laser oscillator, and a plurality of processing units. The processing unit comprises a holding part which movably holds a processed object, an optical system which guides the laser beam, oscillated from the laser oscillator, toward the processed object, a shutter which selectively prevents the laser beam from reaching the processed object, and an individual control device which controls an operation of the holding part, and transmits a laser request signal to the overall control device. When at least one of the plurality of individual control devices transmits the request signal, the overall control device controls the shutter of the processing unit, which has transmitted the laser request signal, to enable the laser beam to reach the processed object, and drives the laser oscillator to allow the laser oscillator to oscillate the laser beam.

Disclosed is a structure such that when pad clips are to be mounted, it is possible to handle return springs and the pad clips as integral articles, thereby facilitating mounting work. Constraining sections are provided at both axial ends of each of the pad clips. Furthermore, the return springs are composed of inner spring elements and outer spring elements. These two types of spring elements are helical torsion springs provided with helical sections. Abutting sections are provided on the spring elements, respectively. The abutting sections are pressed against the inner surfaces of the constraining sections by elastic restoring forces. Moreover, the central axes of the coil sections are substantially oriented in the rotational direction of the rotor.
