The present invention relates to a seamless gearbox, particularly for motorcycles, which is mechanically operated e.g. by the rider's foot. The input shaft of the seamless gearbox of the present invention is split into two elements, each of them is connected to the “next” or “previous” gear, that are linked via the system to the torque input (e.g. clutch). The system according to a preferred embodiment of the present invention allows, via mechanical functionality only, to select only the appropriate of the two elements to transmit torque, based on relative speed between the two elements, and avoiding (for safety reasons) to have simultaneous torque transmission to both elements at the same time.

A pump system for supplying lubricant to components of a wind turbine comprises: a pump for pumping lubricant through a fluid circuit of the wind turbine; a drive means for driving the pump; and, a gearbox arrangement arranged to couple the drive means to the pump. The gearbox arrangement comprises a rotatable input shaft configured to be driven by the drive means and a rotatable output shaft configured to drive the pump. The input shaft is rotatable in a first direction of rotation and a second direction of rotation when driven by the drive means. The output shaft is rotatable in the first direction of rotation, and the speed of rotation of the output shaft is determined by an operational mode of the gearbox arrangement. In a first mode of operation, when the input shaft rotates in the first direction of rotation at a first speed of rotation, the gearbox arrangement is configured to drive the output shaft to rotate also in the first direction of rotation at the first speed of rotation. In a second mode of operation, when the input shaft rotates in the second direction of rotation at the first speed of rotation, the gearbox arrangement is configured to drive the output shaft to rotate in the first direction of rotation at a second speed of rotation.

A method of operating a dual bidirectional input to single bidirectional output transmission is disclosed. The method includes providing said transmission. The method includes activating a computer controller capable of receiving torque data signals from a first bidirectional torque input, a second bidirectional torque input, and a single bidirectional torque output. The method includes determining torque input from said first and second bidirectional torque input, and determining whether to transmit torque to said single bidirectional torque output. In cases where it is so determined, the method involves transmitting torque to said single bidirectional torque output.

A commercial vehicle includes at least one driven axle, a service brake, at least one propulsion engine, and wheels. A parking brake function of the vehicle is achieved by a bistable locking means that acts on both wheels. A first and second multi-speed gearbox having respective first and second gear stages are each activated by an actuator and coupled to the wheels. The parking brake function is achieved at least in-part by concurrently activating the first and second gear stages. A computing device is configured to activate the bistable locking means when the commercial vehicle is at a standstill and configured to send a brake request via an electronic signal to an electronic brake control unit to activate the service brake.
