    • In a handheld machine tool having a tool housing, in which a drive motor is situated for driving a drive element equipped with at least one clamping surface, to which a spindle-locking device equipped with a blocking element and at least one spindle cylinder is assigned, the at least one spindle cylinder being able to be clamped in a spindle-lock operation of the spindle-locking device between the at least one clamping surface and the blocking element n order to prevent the drive element from rotating relative to the tool housing, the spindle-locking device has an impingement element, which is developed to impinge on the at least one spindle cylinder with a specified force in the direction of the at least one clamping surface.
    • 在具有工具壳体的手持式机床中,驱动电动机位于其中,用于驱动配备有至少一个夹紧表面的驱动元件,配备有具有阻挡元件和至少一个主轴缸的主轴锁定装置 所述至少一个主轴缸能够被夹紧在所述主轴锁定装置的所述至少一个夹紧表面和所述阻挡元件n之间的主轴锁定操作中,以防止所述驱动元件相对于所述工具壳体旋转, 主轴锁定装置具有冲击元件,冲击元件被开发成以至少一个夹紧表面的方向上以特定的力撞击在至少一个主轴缸上。

    • In a handheld power tool having a planetary gear set which is at least switchable between a first and a second gear and which is assigned a switching annulus gear which is at least shiftable between a first and a second switching position and which has the first switching position in the first gear and the second switching position in the second gear, the switching annulus gear is assigned a synchronization unit which is designed to enable a synchronization of the switching annulus gear with a planet carrier or with a blocking element of the planetary gear set when the switching annulus gear is shifted between the first and the second switching position to switch over the planetary gear set.
    • 在具有行星齿轮组的手持式动力工具中,所述行星齿轮组至少可在第一和第二齿轮之间切换并且被分配有切换环形齿轮,所述切换环形齿轮至少在第一和第二切换位置之间可移动,并且具有第一切换位置 在第二齿轮中的第一档位和第二切换位置中,切换环形齿轮被分配一个同步单元,该同步单元被设计成能够使切换环形齿轮与行星架或与行星齿轮组的阻挡元件同步, 切换环形齿轮在第一和第二切换位置之间移动以切换行星齿轮组。
