Abstract: A motor vehicle has a motor, an inverter, a first power storage device, with a large-capacity characteristic, a second power storage device, with a high-power characteristic, a power converter and a circuit. The power converter has a voltage step down function during power driving. In the circuit, the power converter is connected to the first power storage device and the second power storage device. Thus, the first power storage device and the second power storage device are parallel to each other. During the power driving of the motor, the power converter steps down an output voltage of the first power storage device to supply energy from the first power storage device and the second power storage device to the inverter.

Abstract: Provided is a clutch device configured so that close contactability between a cam surface of a center clutch and a cam surface of a pressure clutch can be improved and torque transmission can be stabilized accordingly. The clutch device (100) includes a center clutch (105) and a pressure clutch (112). The center clutch (105) includes center-side cam portions (107), a pressure clutch slide portion (106), and a lifter plate slide portion (110). The pressure clutch (112) includes pressure-side cam portions (114), a lifter plate (116), and a second center clutch slide portion (113). The lifter plate (116) includes first center clutch slide portions (120). A clearance (C2) between the second center clutch slide portion (113) and the pressure clutch slide portion (106) is set greater than a clearance (C1) between the first center clutch slide portion (120) and the lifter plate slide portion (110).

A clutch apparatus 100 includes a center clutch 105 and a pressure clutch 112, which hold clutch plates 104 placed facing friction plates 103 that are rotationally driven by a driving shaft. The center clutch 105 includes a center-side mating portion 108 mating with internal teeth of the clutch plate 104. In addition, the center-side mating portion 108 includes a protruding tooth 110. The pressure clutch 112 includes a pressure-side mating portion 116 mating with internal teeth of the clutch plate 104. In addition, the pressure-side mating portion 116 includes a run-off 117. The protruding tooth 110 extends over the run-off 117 of the pressure-side mating portion 116, as one of spline teeth forming the center-side mating portion 108.

Abstract: A torque damper apparatus includes an input-side plate having a pair of side plates and rotatably driven in response to drive force from a motor, a center plate coupled to an output shaft and arranged between the pair of side plates, and an elastic transmission body provided between the input-side plate and the center plate to transmit rotary drive force of the input-side plate to the center plate. The input-side plate has, at a plate surface of at least one side plate, multiple weight attachment holes for attaching a balance weight. Each weight attachment hole is formed in a long hole shape extending along a circumferential direction at an outer edge portion of the side plate.

Abstract: A power transmission device has a back torque transmission cam that brings driving clutch plates 6 and driven clutch plates 7 into press contact with each other. This occurs by moving a second clutch member 4b when a rotational force is input to a first clutch member 4a, via the output shaft 3. A pressure member 5 is located at a non-actuation position. A back torque transmission cam can hold abutment between an interlocking member 9 and weight member 8 by moving the second clutch member 4b in a direction of being brought into proximity to the interlocking member 9.

Abstract: Provided are a wet friction plate and a wet multiplate clutch device including the wet friction plates capable of improving the performance for discharging lubricant oil adhering to surfaces of friction members. A wet friction plate 200 includes oil grooves 203 and friction members 210 on a flat plate annular core metal 201. At a surface of a porous layer 211 of the friction member 210, a friction slide surface 213 and lubricant oil recessed portions 214 are formed. The lubricant oil recessed portion 214 has no sharp portion in a pointed shape, such as a corner portion, and is formed with a smooth continuous surface. The multiple lubricant oil recessed portions 214 depressed in a recessed shape with respect to the friction slide surface 213 are formed. In the porous layer 211, hollow portions 212 are formed to have the same formation rate between a portion forming the friction slide surface 213 and a portion forming the lubricant oil recessed portion 214.

Abstract: Provided is a centrifugal clutch configured so that assist thrust can be maintained constant or can be decreased even when a clutch shoe is abraded. The centrifugal clutch 200 includes a drive plate 210 to be rotatably driven by drive force of an engine. The drive plate 210 includes each of swing support pins 214 and the plate-side cam bodies 218. The swing support pin 214 is fitted in a long-hole-shaped pin slide hole 231 formed at a clutch weight 230 to swingably support the clutch weight 230. The plate-side cam body 218 includes a cylindrical roller, and a weight-side cam body 235 of the clutch weight 230 contacts the plate-side cam body 218. The weight-side cam body 235 is formed as such a curved surface that a cam angle when a clutch shoe 233 contacts a cylindrical surface of a clutch outer 240 is the same between before and after abrasion of the clutch shoe 233 progresses.

Abstract: A centrifugal clutch that can suppress the inclination of a clutch weight, realize smooth oscillation, and suppress the uneven wear of a clutch shoe is provided. A drive plate (210) slidably supports a clutch weight (230) and also supports a projection body (218) via a projection body support pin (216). The clutch weight (230) includes a first spring attachment part (231) and a second spring attachment part (234) to which two clutch springs (235) are attached formed, and a driven part (238) that comes into contact with the projection body (218) formed. The projection body (218) and the driven part (238) are formed in a manner that a projection body range (TE) where the projection body (218) and the driven part (238) come into contact overlaps action positions (FP1) and (FP2) of forces (F1) and (F2) of the clutch spring (235) acting on the clutch weight (230) in the thickness direction of the clutch weight (230).
