A drive member selection mechanism is described, including at least one drive member and at least two selector members, wherein the drive member includes a first and second face, and further includes, on each face, at least one projection, and the selector members include, on at least one face thereof, at least one complementary projection arranged to selectively engage with a projection of a drive member, the arrangement being such that the projection(s) of a selector member and the projection(s) of the first face of a drive member may be drivingly engaged in a first torque connection and the projection(s) of a selector member and the projection(s) of the second face of a drive member may be drivingly engaged in a second torque connection, wherein the second torque connection is opposed to the first torque connection.
A drive member selection mechanism comprising at least one drive member and at least two selector members, wherein the drive member comprises a first and second face, and further comprises, on each face, at least one projection, and the selector members comprise, on at least one face thereof, at least one complementary projection arranged to selectively engage with a projection of a drive member, the arrangement being such that the projection(s) of a selector member and the projection(s) of the first face of a drive member may be drivingly engaged in a first torque connection and the projection(s) of a selector member and the projection(s) of the second face of a drive member may be drivingly engaged in a second torque connection, wherein the second torque connection is opposed to the first torque connection.
A selector member for selecting a drive member comprising a substantially annular body having a first face and a second face, wherein at least one projection is arranged on each face, the projection comprising a ramped form having a base in contact with the annular body, sloping surface and a mating surface, and arranged such that the sloping surface on the first face inclines in the opposite direction to the sloping surface on the second face.
A gearbox comprising at least two gears mounted on a shaft and at least three selector members slidably mounted on the shaft, and rotatively coupled thereto, wherein the gears are substantially annular and comprise a first and second face, and further comprise, on each face, at least one projection, and the selector members are substantially annular and comprise, on at least one face thereof, at least one complementary projection arranged to selectively engage with a projection of a gear, the arrangement being such that projections of a selector member and of the first face of a gear may be drivingly engaged in a positive torque connection and the projections of a selector member and of the second face of a gear may be drivingly engaged in a negative torque connection.
