发明名称 Clutch arrangement comprising a shift piston and a piston housing
摘要 A clutch arrangement includes a shift piston and a piston housing. The shift piston is arranged to be displaced in an axial direction relative to the piston housing between at least one gear position and a neutral position. The clutch arrangement also includes a spring element for forcing the shift piston towards the neutral position. The clutch arrangement includes a first return piston and a second return piston arranged on opposite sides of the spring element, and the spring element is accommodated within a recess of the shift piston and is pretensioned between the first return piston and the second return piston. In the neutral position the first return piston is forced by the spring element against a first stop element of the shift piston, defining an end position for the first return piston relative to the shift piston, and the second return piston is forced by the spring element against a second stop element of the shift piston, defining an end position for the second return piston relative to the shift piston.

主权项 1. A clutch arrangement comprising a shift piston and a piston housing, the shift piston being arranged to be displaced in an axial direction relative to the piston housing between at least one gear position and a neutral position, the clutch arrangement further comprising a spring element for forcing the shift piston towards the neutral position, wherein the clutch arrangement comprises a first return piston and a second return piston arranged on opposite sides of the spring element, and the spring element is accommodated within a recess of the shift piston, wherein in the neutral position the first return piston is forced by the spring element against a first stop element of the shift piston, defining an end position for the first return piston relative to the shift piston, and the second return piston is forced by the spring element against a second stop element of the shift piston, defining an end position for the second return piston relative to the shift piston, wherein the spring element is pretensioned between the first return piston and the second return piston such that the shift piston will not be displaced from the neutral position until a three acting upon the shift piston exceeds a pretensioning force of the spring element.
