    • The invention relates to a clutch arrangement (2) comprising a shift piston (3) and a piston housing (4). The shift piston (3) is arranged to be displaced in an axial direction relative to the piston housing (4) between at least one gear position and a neutral position. The clutch arrangement (2) also comprises a spring element (14) for forcing the shift piston (3) towards said neutral position. The clutch arrangement (2) comprises a first return piston (15) and a second return piston (16) arranged on opposite sides of said spring element (14), and said spring element (14) is accommodated within a recess (17) of said shift piston (3) and is pretensioned between the first return piston (15) and the second return piston (16). In said neutral position the first return piston (15) is forced by the spring element (14) against a first stop element (18) of the shift piston (3), defining an end position for the first return piston (15) relative to the shift piston (3), and the second return piston (16) is forced by the spring element (14) against a second stop element (19) of the shift piston (3), defining an end position for the second return piston (16) relative to the shift piston (3).
    • 本发明涉及一种包括变速活塞(3)和活塞壳体(4)的离合器装置(2)。 变速活塞(3)被布置成在至少一个档位和中立位置之间相对于活塞壳体(4)在轴向方向上移位。 离合器装置(2)还包括用于迫使变速活塞(3)朝向所述中立位置的弹簧元件(14)。 离合器装置(2)包括布置在所述弹簧元件(14)的相对侧上的第一返回活塞(15)和第二返回活塞(16),并且所述弹簧元件(14)容纳在 所述变速活塞(3)并且在所述第一回转活塞(15)和所述第二回转活塞(16)之间预张紧。 在所述中立位置,所述第一返回活塞(15)被所述弹簧元件(14)压靠在所述换档活塞(3)的第一止动元件(18)上,限定所述第一回转活塞(15)相对于 变速活塞(3)和第二返回活塞(16)被弹簧元件(14)压靠在变速活塞(3)的第二止动元件(19)上,限定了第二回转活塞的终止位置 16)相对于变速活塞(3)。
