Abstract: In this driving force transmission apparatus, with a simple constitution employing a one-way clutch 20 instead of an electromagnetic clutch, the driving force derived from the motor 33 can be transmitted to the rotating shaft 1 during engine stops, and the driving force of the engine can be transmitted to the rotating shaft 1 during engine operations. Also, the pulley 3 is held against the connecting portion 11 and the fixed-side member 26 by means of first and second two ball bearings 21, 30 disposed axially adjacent to first and second inner cylinder portions 6, 7, respectively, between which the opening portion 5 of the pulley 2 is interposed. This simple driving force transmission apparatus can switch between transmission and non-transmission of driving force from pulley to rotating shaft, and transmits the driving force of a motor directly to the rotating shaft in the non-transmission state.

Abstract: A gear change mechanism is provided which is intended for a gearbox in which changes of the gear ratio in the gearbox are made mechanically in response to actuating signals. The mechanical movements required are as for a conventional gearbox having a H type pattern. A gearbox selector (20) is mounted for movement about an axis and in the direction of the axis. The selector is operable by two actuators (16 and 18), one (16) to move the selector about its axis and the other (18) to move it in the axial direction. Each actuator can be similar having a cylinder and a shaft and annular pistons located about the shaft. For the rotational movement of the selector three positions are required, a neutral, a gear engaged position in one direction and a gear engaged position in the other direction. For movements in the direction of the axis two, three or four positions are required depending upon whether it is a two, three or four rail gearbox.

The shift actuator has an operation lever, with a base portion mounted on the shift lever support mechanism, and a pair of electromagnetic solenoids arranged facing each other, with the acting portion of the operation lever interposed therebetween. The solenoids are inclined with respect to the horizontal direction. A resilient urging member produces an urging force in the direction of operation of the electromagnetic solenoid which operates upward along the inclination.

Abstract: A gear shift device for vehicles with a mechanical, manually operable gearbox (9) for the vehicle (2). A gear level (1) is linked to the hydraulic master (55, 55?, 56, 56?) to respective slave cylinders (8, 18) for engagement or disengagement of gears during a manual mode of operation for the gear shift device.

Abstract: A gear made of a resin includes a substantially cylindrical rim having a plurality of teeth formed around an outer periphery thereof, a boss formed about a rotational center of the rim, and a web connecting the boss and the rim to each other. At least one groove is defined along outer surface of each tooth to divide the tooth in a widthwise direction of the tooth. As a result, a portion of the gear, in which the grooves are defined, is deformed in a reduced amount, leading to a reduced amount of deformation such as a warpage or sink in the entire gear, thereby providing an enhancement in tooth flank accuracy. Since the grooves are defined along the outer surfaces of the teeth, a lubricant such as grease can be supplied effectively to tooth flanks by previously applying the lubricant in the grooves.

Abstract: In a movable guide for transmission device in which a guide body is formed from a synthetic resin and comprises a chain-contacting shoe and a plate-receiving portion formed as a unit with the shoe on the back side thereof, the plate-receiving portion has plural, longitudinally extending slots, each receiving a reinforcing plate. The plural reinforcing plates improve the bending rigidity, toughness, strength and wear properties of the guide, prevent falling down of the guide and guide torsion, ensure stable travel of the chain, and prevent running of the chain off the guide in a widthwise direction. Improved compactness of the guide and of the overall mechanism, is made possible by the use of plural plates. The plates can be connected to one another by a tensioner-contacting portion, formed as a unit with the plates.

Abstract: Variable inertia flywheels are used in power generation apparatus to quickly release stored kinetic energy to meet transient power load demands. Such flywheels typically vary inertia by using either interconnected multiple flywheels having different inertia or by mechanically moving a mass connected with the flywheel radially with respect to the axis of rotation. A variable inertia flywheel according to the present invention comprises a body and a number of fluid movement devices disposed at equal angular intervals about the rotational axis of the body. Each device comprises at least first and second chambers axially aligned in a substantially radial direction and adapted to contain an electrolytic fluid. The first and second chambers are interconnected by a channel that permits transfer of the fluid between the chambers. The movement of the fluid between the chambers is facilitated by an electromagnetic pump.

The tension-adjusting unit includes a tension roller coming into pressure contact with the slack side of the belt from outside, a swing arm having an end rotatably supported on a transmission case, a link member having an end rotatably supporting a shaft of the tension roller and another end rotatably coupled with another end of the swing arm, and an urging member for swingingly urging the swing arm so that the tension roller presses the belt. A linkage structure having two degrees of freedom is used for supporting the tension roller, so that the tension roller can automatically move to a position where it does not interfere with either pulley at any transmission ratio.
