Abstract:
A saddle-type vehicle can be driven by finer control by judging the driver's demand based on operation of the driver relative to the vehicle when the engine is started from the idle-stop state. A saddle-type vehicle can include bar handle mounted on its opposite tip ends a grasping grip grasped by the driver and a throttle grip for an accelerator operation; an engine controller for automatically stopping an engine and making the engine an idle-stop state: and a clutch. The saddle-type vehicle can include a judgment controller for judging a driver's demand based on operation conditions of the driver relative to the vehicle and a clutch controller for selecting a travel state and a stopped state.
Abstract:
A pressed component is formed by pressing a preform having a tapered tubular portion and a sloping portion provided at an end of the tubular portion and curved in a circular arc. Pressing is performed by a forming die apparatus including a holding body, a piercing punch, and a piercing die. When the tubular portion of the preform is held by an outer fixing and supporting portion of the holding body and an inner fixing and supporting portion of the piercing die, the forming die apparatus cuts off a portion of the sloping portion using an outer cutting edge of the piercing punch and an inner cutting edge of the piercing die and then causes a pressing portion of the piercing punch to bend and press the remaining portion of the sloping portion within a forming space to form a corner portion.

Abstract:
A saddle-type vehicle can be configured to perform idle-stop during deceleration corresponding to a driver's demand. In some embodiments, the vehicle comprises a bar handle mounted on its opposite tip ends with a grasping grip grasped by the driver and a throttle grip for accelerator operation; two operation controls for performing braking operation, at least one of which being a first brake and a second brake mounted on tip ends of the bar handle; and an engine controller for automatically stopping an engine and making the engine an idle-stop state. In some cases, the saddle-type vehicle further comprises a judgment controller for judging whether a simultaneous operation of the first and second brakes has been achieved; and the engine controller performs the idle-stop during deceleration of the vehicle when the judgment controller judges that the simultaneous operation of the first and second brakes has been performed.
Abstract:
A saddled vehicle configured to be driven by a driver sitting on a saddle seat and steering with a handlebar can include a grasping grip to be grasped by a driver and a throttle grip for an accelerator operation respectively, two brakes for braking a front wheel and a rear wheel of the vehicle, each having a different braking operation target, and a cruise control for performing automatic propulsion control of the vehicle wherein the control by the cruise control is performed by changing a control degree in accordance with operation conditions of the first brake and the second brake.
Abstract:
A power transmitting apparatus comprising a switching device for switching an urging device between an urging force applying position wherein an abutment between the other end of the urging device and the pressure member is kept to apply the urging force of urging device to the pressure member when the intermediate member is moved toward the pressure member, and an urging force cutting-off position wherein the other end of the urging device is separated from the pressure member to cut-off the urging force of urging device to the pressure member when the intermediate member is moved toward the pressure member. In some embodiments, the urging device is set at the urging force applying position while the intermediate member is stopped when the vehicle is stopped and the urging device is set at the urging force cutting-off position while the intermediate member is rotated when the vehicle is running.
Abstract:
An integrated member can comprise different members each formed of materials having different mechanical characteristics. A method for manufacturing such an integrated member can comprise an electric resistance welding step in which the first member is press-fit into the second member and the press-fit portion can be electrically energized to achieve the electric resistance welding so as to integrate the first member and the second member. The method can further comprise a carburized layer forming step in which carburizing-quenching and tempering, or carbonitriding-quenching and tempering, is performed on the integrated member obtained in the electric resistance welding step to form carburized layers therein in accordance with the mechanical characteristics of the first member and the second member.
Abstract:
Provided are a surface modification apparatus for an alloy steel component, a surface modification method for an alloy steel component, and a method for manufacturing an alloy steel component, which can provide a deep and homogeneous hard layer for a steel component with a wide shape or a large amount of such steel components. A surface modification apparatus 100 includes a process furnace 101, and the process furnace 101 performs a surface modification process on an alloy steel component 90 including an alloy steel material to which at least one kind of nitride formation element such as chromium, molybdenum, or aluminum is added. The surface modification apparatus 100 forms a compound layer on a surface of the alloy steel component 90 by exposing the alloy steel component 90 for at least 180 minutes to an atmosphere in the process furnace 101 maintained to have an ammonia gas concentration of 80% or more and a temperature of 620° C.
Abstract:
In some embodiments, a torque damper apparatus can achieve reduced stiffness as well as sufficient vibration absorbing property while increasing the dampening ratio of the torque variation. In some embodiments, a torque damper apparatus comprises an input member to which an engine torque is inputted; damper springs able to absorb variation of torque inputted from the input member; and/or a driving power of the engine configured to be transmitted to an output shaft of a vehicle via the input member and the damper springs. The damper springs can comprise a plurality of coil springs arranged along the circumference of the input member. The torque damper apparatus can further comprise a plurality of separate members interposed between the damper springs and configured to be independently rotated with respect to each other when the engine torque is transmitted thereto.
Abstract:
A power transmitting apparatus for transmitting or cutting-off the rotational driving power inputted to an input member to or from an output member by press-contacting or releasing the press-contacting force between driving-side clutch discs and driven-side clutch discs, wherein the power transmitting apparatus comprises interlocking members (e.g., a first member and second member) interlocking with the motion of the weight members from their radially inward positions to radially outward positions and movable toward a direction approaching to the pressure member; and elastic members interposed between the interlocking members and the pressure member and able to move the pressure member toward a direction for press-contacting the driving-side clutch discs and the driven-side clutch discs by urging the pressure member according to the movement of the interlocking members and also able to absorb the urging force of the pressure member applied to interlocking members when the actuating member is operated.
