  • Publication number: 20220227597
    Abstract: Provided is a wound body formed by winding a long sheet. The wound body is supportable by a support shaft. The support shaft includes a cylindrical outer peripheral part that includes a first projection located at a proximal end and a second projection located at a distal end, and includes an inner peripheral part that includes a first recess part located at the one end and recessing outward in the radial direction and a second recess part located to extend from the one end to the other end and recessing outward in the radial direction. A recessing amount of the second recess part is smaller than that of the first recess part. The support shaft and the core body are integrally rotatable around the central axis by engagement of the first projection with the first recess part in a state where the core body is mounted on the outer periphery of the support shaft.

  • Publication number: 20220219852
    Abstract: A support shaft capable of supporting a wound body with a long sheet wound therearound includes a first projection located at a proximal end of an outer peripheral part, and a second projection located at a distal end of the outer peripheral part. A core body of the wound body includes a one-end-side first recess part located at one end of an inner peripheral part, an other-end-side firsts recess part located at an other end of the inner peripheral part, and a second recess part located to extend from the one end to the other end. In a state where the core body is mounted on an outer periphery of the support shaft, the first projection engages the one-end-side first recess part or the other-end-side first recess part.

  • Patent number: 10883547
    Abstract: A dog clutch includes a gear (40) mounted on a power transmission shaft (30), first and second dog rings (10, 20), a fork (60), springs (65), and cam grooves (31). The cam grooves (31) each include a first slope surface (36) inclined from the axial direction toward the positive rotation direction as the first slope surface (36) approaches the gear (40) and a second parallel surface (37) parallel to the axial direction. The first dog ring (10) includes first cam protrusions (16) to be engaged with the respective first slope surfaces (36), and the second dog ring (20) includes second cam protrusions (26) to be engaged with the respective second parallel surfaces (37). This structure prevents the dog rings and the fork from coming into contact with each other, thereby avoiding generation of abrasion and increasing the transmission efficiency.

  • Patent number: 10859139
    Abstract: A vehicle transmission has a plurality of gear positions that are to be selectively established, and includes: an input shaft; a first shaft; a second shaft; an output shaft; at least one first drive gear disposed on the first shaft; at least one second drive gear disposed on the second shaft; at least one driven gear disposed on the output shaft; a dog clutch connecting and disconnecting between the input shaft and each of the first and second shafts; and a synchronous meshing apparatus. The synchronous meshing apparatus connects and disconnects between each of the first and second shafts and the output shaft, and, when connecting between each of the first and second shafts and the output shaft, establishes a power transmission path from each of the first and second shafts to the output shaft via a selected one of the at least one first or second drive gear.

  • Patent number: 10788125
    Abstract: A first dog ring and a second dog ring are biased toward each other by means of springs. When the first dog ring and the second dog ring are moved away from each other, bias force produced by the springs is applied to the second dog ring in a direction to draw the second dog ring toward the first dog ring. Accordingly, when the first dog ring is moved away from the second dog ring during shifting, the second dog ring is drawn toward the first dog ring under the bias force, and third engaging teeth of the second dog ring and meshing teeth of a first-speed gear are promptly disengaged from each other.
