A clutch control system for a transmission for detecting if hydraulic control during shifting is not executed. A first clutch and a second clutch are switched from a disengagement state to an engagement state by receiving a predetermined pressure generated by a hydraulic pump. A transmission executes shifting to an adjacent gear step by operation of switching the engagement state of the first clutch and of the second clutch from one side to the other side. If an elapse time t from the start of clutch switching operation reaches a predetermined time and an input-output speed ratio which is a ratio between engine speed and counter shaft rotational number falls within a predetermined range corresponding to a gear step before shifting, the transmission control unit discontinues the clutch switching operation by stopping the supply of hydraulic pressure to the other side clutch to bring it into the disengagement state.

Clutch control system for transmission

A wheel is provided with a motor having a stator and a rotor and has with a fixed-side member supporting the stator and a rotative-side member receiving rotation transmitted from the rotor. The wheel is supported between a pair of arms with a wheel axle. An axle rotatively supports the rotor and the rotative-side member. An engaging part is provided for engagement with the fixed-side member to position the center of rotation of the rotative-side member with respect to the fixed-side member. The fixed-side member and the rotative-side member are integrated by engagement of the engaging part with the fixed-side member. This configuration allows the axle to be positioned with respect to the fixed-side member, such that the centers of holes in the axle and the fixed-side member for insertion of the wheel axle will be in alignment. The unit U is then incorporated in between the pair of arms.

A vibration damping apparatus for a saddle riding type vehicle that easily secures stiffness of a vehicle body frame, simplifies structure, and improves a degree of freedom in layout. The vibration damping apparatus includes at least a pair of mutually facing surfaces disposed on the vehicle body frame, the surfaces not being relatively displaceable while the vehicle is stationary, and being relatively displaceable while the vehicle is running. A damping member is fixed to each of the surfaces and is disposed therebetween. The damping member is not subject to load while the vehicle is stationary. One of the surfaces is disposed on a side of a first main frame of a pair of left and right main frames and the other of the surfaces is disposed on a side of a second main frame.

Vibration damping apparatus for saddle riding type vehicle

A saddle-type vehicle has an engine-fastening structure which stabilizes a seating face contact between a collar and a vehicle body frame on one side, and between the collar and an engine on the other side. The vehicle includes a vehicle body frame having an engine-supporting portion, and an engine block having a female threaded portion formed therein for alignment with the engine-supporting portion. The collar is interposed between the engine-supporting portion and the engine block. The engine-supporting portion of the frame, the collar and the engine side female threaded portion are fastened together by a bolt. A gap is provided at least at locations between the collar and the bolt which oppose a boundary between the collar and the engine-supporting portion, and another boundary between the collar and the engine side female threaded portion.
