摘要： The disclosed is a deceleration device including a cylindrical brake member fixed to a rotary shaft, a plurality of permanent magnets arrayed in a circumferential direction of a circle around the rotary shaft, a cylindrical magnet holder holding the permanent magnets, and a switching mechanism that switches between a braking state and a non-braking state. The plurality of permanent magnets include primary magnets and secondary magnets that are arrayed alternatively in the circumferential direction. When viewed on a surface facing the brake member, north poles of the primary magnets are circumferentially adjacent to and in contact with north poles of the secondary magnets, and south poles of the primary magnets are circumferentially adjacent to and in contact with south poles of the secondary magnets. The magnetic holder is ferromagnetic.

摘要： A crankshaft includes journals serving as a central axis of rotation, crank pins decentered from the journals, and crank arms connecting the journals and the crank pins. Some or all of the crank arms have counterweights integrated therewith. At least one of the crank arms has a recess in a crank pin facing surface. The crank arm includes ribs formed respectively in two side portions of the recess along a periphery of the crank arm.

摘要： A braking actuator uses a single cylinder without using a spring to achieve a 3-position operation. A partition plate and an intermediate check plate are affixed within a cylinder at suitable intervals in the axial direction. Inserted movably in the axial direction of the cylinder are a first piston disposed between a pressing lid and the intermediate check plate, a second piston disposed between the intermediate check plate and the partition plate, and a third piston disposed between the partition plate and a pressing lid. A rod which is axially movable within the cylinder has a base end attached to the third piston and a tip end which extends outside from the cylinder through the partition plate, the second piston, the intermediate check plate, the first piston, and the pressing lid. A stopper affixed to a middle portion of the rod moves the first piston or the second piston.

摘要： An eddy current retarder includes a brake drum, a magnet retention ring, and a switch mechanism. The brake drum is fixed to a rotating shaft. The magnet retention ring is arranged inside the drum and retains magnets at regular intervals entirely in a circumferential direction such that the magnets face the inner peripheral surface of the drum. The switch mechanism includes switch plates that switch, during braking, to a state in which magnetic circuits develop between the magnets and the drum, and switch, during non-braking, to a state in which no magnetic circuits develop. Protrusions are provided on an end face of the drum at regular intervals entirely in the circumferential direction. Electricity generating coils are provided in a non-rotating part of a vehicle at regular intervals entirely in the circumferential direction such that the electricity generating coils face the regions of the end face of the drum.

摘要： A crankshaft includes: journals that define a central axis of rotation; crank pins that are eccentric with respect to the journals; and crank arms for connecting the journals and the crank pins, wherein each of the crank arms or at least one of the crank arms integrally includes a counterweight. The crank arms have a recess in a surface adjacent to a corresponding one of the journals, the recess disposed inward of a peripheral region along a periphery of the surface, the recess disposed along the peripheral region. With this configuration, it is possible to provide a crankshaft which has reduced weight and increased torsional rigidity in combination with increased flexural rigidity.

摘要： This fluid-type retarding device includes: a rotating disk provided to a rotating shaft; a rotating housing that includes paired disk portions and a cylinder portion connecting outer circumferential portions of the disk portions so as to surround the rotating disk, and is rotatably supported with the rotating shaft; and a friction brake that presses a friction member against the rotating housing at the time of braking to bring the rotating housing to a stop. On at least one surface of the rotating disk, a disk vane extending from an inner circumference of the surface toward an outer peripheral side is formed, and on an inner surface of each of the paired disk portions corresponding to the disk vane, a housing vane extending from an inner circumference to an outer periphery is formed. Furthermore, working fluid is accommodated within the rotating housing.
