摘要:
An automatic transmission has an automatic shift mode and a manual shift mode. When an opposite manual operation is performed, during an automatic shift based on a shift map in the automatic shift mode, in an opposite direction opposite to the automatic shift or when the opposite manual operation is performed, during a forced shift performed regardless of the manual operation in the manual shift mode, in the opposite direction opposite to the forced shift, a control apparatus forbids a shift based on a first manual operation and permits a shift based on a second or subsequent manual operation in the opposite direction opposite to the automatic shift or the forced shift.

A two-wheeled motor vehicle highly durable and having a large space under a seat. A cover member (11) has an inner space (11a), at least a part of which is positioned between an engine unit (20) and the seat (14). The engine unit (20) is rockably supported by a vehicle body frame (10). The center axis (38a) of a cylinder (38) extends obliquely upward and forward from a crankcase (32). Oil sumps (99a, 99b) are respectively formed at the bottom of a crank chamber (35) and the bottom of that portion of a transmission chamber (51) which is on the front side of a transmission case (50). The oil sumps (99a, 99b) are connected to each other by a communication route (24). That bottom surface of the transmission chamber (51) at which the oil sump (99) is formed is located below the bottom surface of that portion of the transmission chamber (51) which is located behind the oil sump (99).

A dual clutch transmission includes a group of odd-numbered speed drive trains, including at least a first speed drive train to be driven for setting a first speed serving as the lowest speed; a first clutch to be engaged for driving any one of the odd-numbered speed drive trains including the first speed drive train; a group of even-numbered speed drive trains, including at least a second speed drive train to be driven for setting a second speed serving as the second lowest speed; a second clutch to be engaged for driving any one of the even-numbered speed drive trains including the second speed drive train; an automatic speed control system for selecting one of all the odd-and-even numbered speed drive trains to be driven, and for selecting either the first or second clutch to be engaged for driving the selected speed drive train, in correspondence to a traveling speed of a vehicle equipped with the dual clutch transmission; and a manual selection device for selecting any one of all the odd-and-even numbered speed drive trains, including the second speed drive train and excluding the first speed drive train, as a starting-and-stopping speed drive train to be driven when the vehicle starts and immediately before the vehicle stops.
摘要:
A gear position in an automotive gearbox is detected on the basis of measuring a value indicative of the speed of a rotating shaft between an engine (11) and the gearbox (4), and a value indicative of the speed of an output shaft (9) from the gearbox, and calculating a quotient of these two speeds. If for a predetermined period of time the quotient is between upper and lower limits about a quotient value pertaining to the respective gear position, it is decided that a gear position obtains. Information about a selected split position of a split gear is used to rule out as possible gear positions all gear positions which do not correspond to the selected split position, thereby enabling said upper and lower limits to be raised and lowered respectively for the remaining gear positions which correspond to the selected split position.

Die vorliegende Erfindung betrifft eine Getriebeschaltstelle (10) zum Herstellen einer drehfesten Verbindung zwischen mindestens einem Zahnrad (16, 18) und einer Welle (12). Die Getriebeschaltstelle (10) umfasst eine Welle (12), eine Schaltmuffe (14) und zwei Zahnräder (16, 18). Die zwei Zahnräder (16, 18) sind jeweils drehbar relativ zur Welle (12) gelagert. Die Schaltmuffe (14) ist auf der Welle (12) verdrehsicher gelagert. Die Schaltmuffe (14) und die Zahnräder (16, 18) sind derart ausgebildet, dass zwischen der Schaltmuffe (14) und jeweils einem Zahnrad (16, 18) eine formschlüssige drehfeste Verbindung herstellbar ist. Um Probleme hinsichtlich eines Schaltlochs bzw. einer Verblockung des Getriebes zu verbessern, wird vorgeschlagen, dass die Schaltmuffe (14) derart mit den zwei Zahnrädern (16, 18) zusammenwirkt, dass stets zumindest eine formschlüssige drehfeste Verbindung zwischen der Schaltmuffe (14) und einem der Zahnräder (16, 18) hergestellt ist.
摘要:
A derailleur control apparatus (110) comprises a control unit (130) that receives shift control signals. The control unit (130) provides a first signal to operate the derailleur a first distance from a first sprocket to a second sprocket in response to a first shift control signal received while operating in a riding mode, and the control unit provides a second signal to operate the derailleur a second distance less than the first distance in response to a second shift control signal received while operating in the riding mode.
