  • Publication number: 20200282946
    Abstract: Provided is an airbag configured so that, in the inflated state thereof, a recess is formed in a chest restraint area in the passenger facing surface of the airbag, and the portion of the airbag other than the recess has a large inflation thickness. A driver-side airbag 1 is formed by sewing a front panel 2 and a rear panel 3 together. The rear panel 3 is provided with a left tuck portion 12 which extends from the upper left to the lower left, and a right tuck portion 11 which extends from the upper right to the lower right. The tuck portions 11 and 12 increase the inflation thickness of the driver-side airbag 1. A recess 6 is formed in a passenger chest restraint area in the driver-side airbag 1 by a tether 20.

  • Patent number: 10738886
    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.

  • Patent number: 10711895
    Abstract: A control apparatus for a vehicle transmission that includes: transmission gears disposed on a shaft; a switching mechanism which is to be switched between a connecting state in which one of the transmission gears is rotatable integrally with the shaft and a disconnecting state in which the one of the transmission gears is rotatable relative to the shaft; a shift fork for axially moving the switching mechanism; and a shift barrel to be rotated to position the shift fork. The switching mechanism includes first and second rings and an elastic member which is disposed between the first and second rings in the axial direction and connects the first and second rings. The control apparatus determines that a failure occurs in the vehicle transmission, when a value related to a reaction force that acts on the shift barrel during rotation of the shift barrel is deviated from a predetermined range.

  • Publication number: 20190301605
    Abstract: A control apparatus for a vehicle transmission that includes: transmission gears disposed on a shaft; a switching mechanism which is to be switched between a connecting state in which one of the transmission gears is rotatable integrally with the shaft and a disconnecting state in which the one of the transmission gears is rotatable relative to the shaft; a shift fork for axially moving the switching mechanism; and a shift barrel to be rotated to position the shift fork. The switching mechanism includes first and second rings and an elastic member which is disposed between the first and second rings in the axial direction and connects the first and second rings.

  • Publication number: 20190242442
    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.

  • Publication number: 20190235474
    Abstract: A method for generating a numerical control program includes first-fourth steps. In the first step, elements related to the shape of a material are created on the basis of information related to the shape of the material. In the second step, processing is executed in which the elements related to the shape of the material which were created in the first step are read into areas to be subjected to processing in the third step. In the third step, a tool path is generated for each element read in the second step. In the fourth step, the tool paths generated for each element in the third step are connected.

  • Patent number: 8382640
    Abstract: This apparatus is provided with a clutch mechanism 14. The clutch mechanism 14 is interposed between an engine 11 and a transmission 15, and is coupled to a clutch pedal 28. An operating mode of the clutch mechanism 14 changes in conjunction with a change of an operating position of the clutch pedal 28. In the case that an execution condition is met, the apparatus lowers a maximum operating speed of the clutch mechanism 14 in comparison with a state in which an execution condition is not met. The execution condition includes the following execution start condition that “the operating position of the clutch pedal 28 is a position setting the clutch mechanism 14 to a disengaged state, and a changing speed of the operating position of the clutch pedal 28 in an engaging direction at a time of setting the clutch mechanism 14 to an engaged state from the disengaged state is equal to or higher than a predetermined starting speed”.
