A wheeled vehicle is disclosed. The wheel of the vehicle may be a powered wheeled vehicle with an engine and a transmission system. The transmission system may be used to select a gear ratio to a powered wheel of the wheeled vehicle, such as a single wheel.

A gearbox for a motor vehicle, includes multiple gears, a housing, an interior space enclosed by the housing, a gearshift clutch located in the interior space, through which a gear can be shifted, and a shifting device for transmitting an external actuating force acting outside the housing for shifting to the gearshift clutch, the shifting device having an inner shifting part in the interior space, a first introduction element which engages through a first opening provided in the housing for guiding the external actuating force to shift the gear to the inner shifting part, a shifting mass arranged outside the housing which is moved during gear shifting, and a connecting element different from the first introduction element with which the shifting mass is connected to the inner shifting part, the connecting element engaging through a second opening different from the first opening in the housing into the interior space.

A transmission case 210 supports a shift shaft 222 that constitutes a part of a speed change operation mechanism 220, and which receives an operating input and transmits a speed change motion of a transmission 201. A part of a transmission holder 162M in which part the shift shaft 222 is disposed includes a shaft insertion opening portion 162g that the shift shaft 222 is disposed so as to pass through.

A shifting operation detecting apparatus includes a gearbox and a shift change apparatus. The shift change apparatus includes a shifting operation unit, a shifting operation receiving section, a swing lever and a connecting member. A shift operation detector is disposed between the swing lever in an outer shaft section of the shifting operation receiving section and a gearbox case to directly detect a pivoted state of the shifting operation receiving section, and the connecting member is connected to the swing lever from the gearbox case side.

Described herein is a gearbox for a motor vehicle including a plurality of forward gear ratios and a reverse gear ratio, the gearbox further including: a control device (configured for controlling the selection and the engagement of said forward gear ratios and of said reverse gear ratio; and a plurality of engagement devices that can be controlled by means of said control device for engaging the forward gear ratios or reverse gear ratio (RM) of the gearbox that are operatively associated to said devices. The gearbox includes a locking device, which is electrically controlled and configured for preventing actuation of the engagement device associated to a predetermined forward gear ratio, said locking device being configured for being actuated above a threshold speed of the motor vehicle on which said gearbox is installed.

Disclosed herein is a gear actuator for a double clutch transmission, which includes a power module (100), including odd and even-numbered stage select solenoids and shift motors, a controller directly connected to them, and select levers connected to select rods of the select solenoids, shift modules (200) for transmitting the rotational forces of the shift motors to a control shaft assembly (300), the control shaft assembly (300) for transmitting the operating force of the power module (100) to a shift lug, and a body housing (400) having the power module (100), the shift modules (200), and the control shaft assembly (300) installed therein. Accordingly, the gear actuator can have a more compact structure and be easily assembled by modularization.

A transmission assembly for a powertrain of a vehicle, includes, a control device and a transmission housing for housing a transmission, the control device mountable to the transmission housing and including a transmission mounting surface adapted to face the transmission housing, the transmission housing including a control device mounting surface adapted to face the control device, one of the transmission mounting surface and the control device mounting surface including a groove including at least a first and a second step deeper than the first step, and the other of the transmission mounting surface and the control device mounting surface including an outwardly extending guiding member configured to be received in the groove, configured so that the outwardly extending guiding member can slide in the first step until it reaches the second step, whereafter the transmission mounting surface can be moved towards the control device mounting surface or vice versa.

A medical device drive system can include a rotational input, a coupling member engaged with the rotational input, a first gear having an engagement feature sized and shaped to engage with the coupling member, and a second gear coupled with the first gear, the second gear coupled to a movable element. The system can have a first system state and a second system state. In the first system state the coupling member is not engaged with the engagement feature and the first gear rotates without moving the coupling member. In the second system state the coupling member is engaged with the engagement feature of the first gear and rotation of the rotational input turns the coupling member, the first gear, and the second gear to move the movable element.

A rolling bearing arrangement is provided for a switching device for switching a manual transmission. The rolling bearing arrangement includes at least one rolling bearing having an outer shell, a cage axially displaceable in the outer shell, and a plurality of rolling elements guided by the cage and radially supported on the outer shell. A rod having a switch axis is supported rotatably and axially displaceably by the rolling elements. The rod has an axial stop for securing the cage in a form-fitting manner with vertically aligned rod in an upper position against a downward axial displacement.

A bushing assembly is configured for a vehicle transmission shift shaft, the shift shaft having a first diameter, a shift lever fixedly mounted to an end thereof, and a step defining a second diameter smaller than the first diameter along a length thereof. The bushing assembly includes a seal, a spacer, such as a spacer sleeve, and a bushing. The seal is positioned on the shaft abutting the shift lever, the spacer is positioned on the shaft abutting the seal, and the bushing is positioned over the spacer. A kit for replacement of an OE bushing and a method to replace a bushing are also disclosed.
