An orifice and a one-way valve for permitting a flow of a liquid only in one direction from a primary master cylinder to an input port in a secondary master cylinder of a brake system are incorporated in parallel in an hydraulic pressure introduction passageway which connects the input port in the secondary master cylinder and an output port in the primary master cylinder. Thus, it is possible to moderate a kick-back phenomenon due to a back-flow of a pressure oil from a hydraulic pressure chamber in the secondary master cylinder via the input port toward the primary master cylinder, and to rapidly fill a brake oil in the secondary master cylinder from the side of the primary master cylinder.

A motorcycle braking system distributing liquid pressure to a first front brake, a second front brake and a rear brake includes a first master cylinder actuated by a front brake lever and a second master cylinder actuated by a back brake pedal. The first master cylinder is connected directly to the first front brake and the second front brake. The brake system also employs a pressure controller that distributes liquid pressure from the first and second master cylinders to the second front brake according to the liquid pressure from the second master cylinder. A secondary master cylinder supplies a secondary liquid pressure to the rear brake in response to actuation of the first front brake. The secondary liquid pressure supplied to the back brake is transformed by a pressure-transformer. Using these components, the braking system implements a braking control method that provides improved control of the motorcycle while braking.

A transmission for a vehicle for performing a shift manipulation at a desired time while ensuring a favorable operation feeling. A lost motion member is arranged in a shift drive force transmitting mechanism arranged between a shift spindle and a shift drum, and a rotary position of the shift drum is resiliently held by a shift stopper mechanism in a state where one of a plurality of sear trains is established or in a neutral state. A state which allows a changeover operation of an established state of a plurality of gear trains due to an action of a shift drive force which is temporarily accumulated by a lost motion means and a state which interrupts the changeover operation can be changed over by a shift restricting mechanism which is provided as a part separate from a shift stopper mechanism.

A clutch operation mechanism wherein when a clutch is disengaged and engaged by manual operation or by operation of an actuator the one operation does not affect the other operation. The clutch operation mechanism includes a lever side lost mechanism which is disposed between a clutch lever and a turn-operating force transmitting member for interrupting, from the clutch lever side, an operated-force applied from the turn-operating force transmitting member by driving the electric motor when the clutch lever is not operated. A motor side lost mechanism is disposed between the electric motor and the turn-operating force transmitting member and interrupts, from the side of the electric motor, the operated-force applied from the turn-operating force transmitting member by operating the clutch lever when the electric motor is not operated.

A protective guard member is provided in order to protect a high-voltage wire connected to a control unit in an electric vehicle, in which the control unit, for controlling a drive motor of the vehicle, is mounted to a rear swing arm thereof. The high-voltage wire protecting guard member may be provided as a guard arm of a main vehicle support stand, arranged to shield the external side of the high-voltage wire, when the support stand is in a stored position thereof. The guard arm may be configured to protectively shield a water supply pipe and a water discharge pipe for a cooling plate associated with the control unit, as well as protecting the high-voltage wire, when the support stand is in the stored position thereof.
摘要:
A device for introducing air into the exhaust system of a V-type motorcycle engine. The device includes an air manifold advantageously positioned within the V of the engine with passages extending to each exhaust passage adjacent each exhaust port. A control valve run by vacuum admits air to the manifold while reed valves control the passageways to each exhaust passage. The portion of the passage extending through the cylinder head in one embodiment includes a simple bore in tangential intersection with the exhaust passages. A pipe is positioned within the bore which has nozzles therethrough for proper introduction of air to the exhaust.

A clutch hydraulic system for a vehicle wherein it is possible to independently operate two systems, to increase the degree of freedom in designing, and to achieve a reduction in cost. A seesaw member for transmitting motive power is provided between a second release cylinder and a first master cylinder, the first master cylinder and a second hydraulic oil pipe communicate with each other through a large diameter hole and a small diameter hole provided as communicating passages through which oil flows. A reservoir tank is provided for reserving the oil for controlling the amounts of the oil in the hydraulic oil passage on the side of the first master cylinder and the amount of the oil in the hydraulic oil passage on the side of the second release cylinder is connected to a second master cylinder.
