A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets controls the shift actuator with actuating and opposing pulses, and interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

A power train component such as a gearbox includes driving and driven, coaxially arranged cooperating gears which engage each other via teeth. The engaging end surfaces of the teeth are provided with a first chamfer and a second chamfer, in which the chamfer edge is offset from bisecting the tooth. Preferably the offset chamfer edges are provided on both a driving gear (shifter), axially positionable using a shifting fork on a shift drum, and a driven low gear. In one preferred driving gear (shifter) design, the offset chamfer edges are only provided for the side engaged when the shifting fork moves against a spring force. The invention facilitates smoother and less binding movement between the non-engaged and the engaged axial positions, such that the gear can be more easily shifted by the shifting fork in at least one direction.

A locking system for a narrow package differential with a locking collar, a ring gear and a side output gear is provided. The locking collar has at least one locking tab. The ring gear has at least one ring gear slot and an opening section in each ring gear slot. The at least one ring gear slot receives the at least one locking tab of the locking collar. The side output gear has at least one side gear slot. The side output gear is positioned such that the at least one side gear slot can be accessed through the opening section in the ring gear slot. The at least one locking tab of the locking collar in the ring gear slot is selectively received within the side output gear slot to selectively place the differential in a locking configuration.

The invention relates to a motor-vehicle accessory, comprising a moveable first part and a vehicle-fixed second part, wherein the first part is guided on the second part by a guide (43), wherein the guide (43) comprises at least one rack (22a, 22b, 24a, 24b) in engagement with a gear (21a, 21b, 23a, 23b), wherein the rack (22a, 22b, 24a, 24b) is on one of the parts, and the gear (21a, 21b, 23a, 23b) is on the other part.

The particular feature consists in that the guide additionally comprises a tolerance compensation that comprises at least one running rail (26a, 26b, 28a, 28b) on one of the parts and engages a running wheel (25a, 25b, 27a, 27b) on the other one of the parts, wherein the running wheel (25a, 25b, 27a, 27b) and/or the running rail (26a, 26b, 28a, 28b) is elastically deformable, and a press-fit is formed between the running rail and the running wheel, so that the meshing teeth of the first part and of the second part are urged into a defined position.

A linkage-based shifting assembly comprises first and second arms, having a first wheel rotatably coupled to a proximal end of the first arm and a second wheel rotatably coupled to a proximal end of the second arm. A shifting assembly is configured to couple to a chassis, wherein the shifting assembly is coupled to distal ends of the first and second arms and configured to cause a relative shifting motion between the chassis and the first and second wheels. The linkage-based shifting assembly can form part of a vehicle. The vehicle can be a two-wheeled vehicle. The vehicle can be a mobile carrier. The mobile carrier can be a two-wheeled vehicle.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.
