摘要:
A friction plate for a wet-type multiplate clutch is provided with a core plate and friction linings bonded on opposite sides of the core plate, respectively. Each of the friction linings is composed of plural segment pieces each having at least one first oil groove and at least one second oil groove. The first oil groove opens to a radially-inner side of the friction plate and has a closed end portion located in a radially-intermediate part of the friction lining, and the second oil groove opens to a radially-outer side of the friction plate and has a closed end portion located in another radially-intermediate part of the friction lining. The second oil groove has a shape that its angular width becomes narrower from its open end portion toward its closed end portion thereof, and at the open end portion, the angular width of the second oil groove is reduced. The first oil groove may be provided with an oil pocket at its closed end portion.

A friction plate for a wet-type multiplate clutch is provided with a core plate and friction linings bonded on opposite sides of the core plate, respectively. Each of the friction linings is composed of plural segment pieces bonded at angular intervals on the corresponding one of said opposite side. The segment pieces each have at least one first oil groove and at least one second oil groove. The first oil groove opens to a radially-inner side of its corresponding segment piece and has a closed end portion located in a radially-intermediate part of the corresponding segment piece. The second oil groove opens to a radially-outer side of the corresponding segment piece and has a closed end portion located in another radially-intermediate part of the corresponding segment piece. Each two adjacent ones of the segment pieces are provided, in radially-middle parts of opposing side walls thereof, with angularly-extending recessed portions, respectively.

In a torque converter equipped with a lock-up clutch device, a friction member is put on either one of a front cover and a lock-up piston which are to be brought into contact. On the front cover, coupling members are welded for coupling with an engine. Owing to welding distortion, convex portions are generated on a friction face. Thus, when the friction member is put on either side of the front cover and clutch piston, if relative rotation slippage occurs therebetween, a positive pressure and a negative pressure are produced in front of and behind each convex portion, which leads to the stick/slip. This invention gives grooves 71 each exceeding the range of a welding portion 61 of the coupling member 6 which are formed on the friction face of the friction member 7, which realizes balancing in a change in pressure.

A friction plate for a wet-type multiplate clutch provided with a core plate and friction linings fixed on opposite sides of the core plate, respectively. Each of the friction linings is formed such that at a section thereof located on a side radially inner than a radial center line thereof, the friction lining has a thickness that gradually increases from an inner circumferential portion of the section toward an outer circumferential portion of the section.

A boost chopper circuit converts AC power to DC voltage and supplies the DC voltage to a load. The boost chopper circuit includes a switching element and a reactor. A controller ON/OFF controls the switching element based on a comparison result in an interval of the former half of a half cycle of the AC power between a detected input current by a input current detector and a current instruction value of a modeling waveform obtained by reducing a harmonic component of a predetermined order from the current waveform.
