A dog clutch control apparatus for an automated transmission includes a dog clutch transmission mechanism including a clutch ring, a clutch hub, a sleeve, an axial driving device, a dog clutch portion, a stroke position sensor, and a spline of the sleeve including high teeth and a low tooth, the dog clutch portion including clutch front teeth and clutch rear teeth, wherein in a rotation adjustment range, a control apparatus controls a thrust load of the axial driving device so that a first thrust load is applied to the sleeve, and the first thrust load generates a relative rotation between the sleeve and the dog clutch portion against a frictional force generated by contact between an end surface of each of the high teeth and a front end surface of each of the clutch rear teeth.

Dog clutch control apparatus for automated transmission

An automatic shift device for an automated transmission for a vehicle includes a rotation shaft, a clutch ring, a clutch hub, a sleeve, a dog clutch portion, a shaft moving apparatus, and a control portion. The control portion includes a push force reduction control portion performing a push force reduction control reducing a push force of the sleeve that the shaft moving apparatus applies on the clutch rear teeth in response to a back and forth movement of the sleeve after the sleeve reaches an end surface of the clutch rear tooth. The control portion includes a retry control portion performing a retry control that re-applies the push force of the sleeve in response to a predetermined retry condition after the push force reduction control is performed.

Automatic shift device for automated transmission for vehicle

A dog clutch control apparatus for an automated transmission includes a rotary shaft, a dog clutch transmission mechanism including a clutch ring, a clutch hub, a sleeve including a spline, an axial driving device, a dog clutch portion provided at the clutch ring, a rotation speed detection sensor, the spline including high teeth and a low tooth, clutch rear teeth and clutch front teeth formed at the dog clutch portion, and a control unit controlling an operation of the axial driving device based on a deceleration gradient of a rotation speed of either one of the sleeve and the clutch ring detected by the rotation speed detection sensor and controlling the axial driving device so that a decreased thrust load is applied to the clutch rear teeth from the sleeve in a case where the deceleration gradient is smaller than a first predetermined value.

An air intake control valve includes a body extending to divide an inner portion of a surge tank of a multi-cylinder internal combustion engine into two portions, the body serving as a divided surface to divide the inner portion of the surge tank into the two portions, a valve element operated to rotate for opening and closing a fluid passage formed at the body, and a seal member sealing between a sealed surface of the surge tank and an outer periphery of the body, the seal member including a seal portion constituted by two contact portions that make contact with the sealed surface in a state where the two contact portions extend in directions opposite from each other relative to the divided surface.

Air intake control valve

A fluid control valve, which includes a body forming a fluid passage and including a sealing surface positioned in the fluid passage, a valve body configured to rotate between an open position and closed position within the fluid passage, an elastic sealing member provided at a rim portion of the valve body, and a lip portion extended from the elastic sealing member to be directed towards a center portion of the valve body. The lip portion contacts the sealing surface and a surface of the lip portion facing the sealing surface is exposed to the fluid passage.
