Abstract

A lay-shaft assembly (10) for use in a vehicle transmission, comprising a lay-shaft (12) which is rotatable around a central axis (14), a first gearwheel (16) rotatable around the lay-shaft and the central axis, a second gearwheel (18) fixedly connected to the lay- shaft and rotatable with the lay-shaft around the central axis, and a clutching assembly (20) rotatable around the lay-shaft and the central axis. The clutching assembly (20) comprises a driven gearwheel (22) and clutching mechanism for selectively coupling the rotation of the driven gearwheel (22) to either the first gearwheel (16) or the second gearwheel (18). The clutching assembly (20) has a first axial end (24) and a second axial end (26) opposite the first axial end. The first gearwheel and the second gearwheel are arranged on a part of the lay-shaft extending from the first axial end (24) of the clutching assembly (20).

Description

technical field [0001] The present invention relates to a countershaft assembly for use in a vehicle transmission. Background technique [0002] Most vehicle transmissions in modern vehicles include synchronized gearboxes. Such synchronized gearboxes typically include an input shaft coupled to the engine crankshaft and an output shaft in line with the input shaft and coupled to the wheels of the vehicle. To rotationally couple the input shaft to the output shaft, a typical vehicle transmission includes one or more countershaft assemblies. Such countershaft assemblies include a countershaft rotatable about a central axis and provided with at least three gears. Typically, one of those gears is fixedly connected to the layshaft, while the other gear can be selectively coupled to the layshaft by means of a clutch mechanism. The clutch mechanism is usually located between the connectable gears so that they can be controlled by a single operating lever, such as a shift fork. G...
