摘要： The invention relates to a hand-held working tool, comprising a first unit, powered by a vibration on operation and a second unit (2) which may be displaced relative to the first unit (1). A vibration isolation device (3) is arranged between the first and second unit, comprising an actuator (4), for generation of a control force, by means of which the operational force acting in the working direction (A) between the first (1) and the second unit (2) may be at least partly compensated. The actuator (4) is pneumatically operated and comprises an air spring (11) for vibration isolation. A working piston (7) in an air spring percussion device on the working tool serves to supply compressed air for the air spring (11). Alternatively, the compressed air can be supplied by the oscillating relative movement between the first unit (1) and the second unit (2).

摘要： The invention relates to a demolition hammer and/or hammer drill comprising a percussion generating device having a percussion piston moving axially back and forth. In a main percussion mode, the percussion piston impinges upon a tool (18) which can move along a limited axial path straight into a main percussion direction. In a free percussion mode, said percussion piston indirectly impinges upon a percussion changing device (54), and by means thereof upon the tool (18), in a free percussion direction opposite to the main percussion direction. The impact surface of a tool shaft (16) and the impact surface of a free percussion ram (38) are placed opposite an impact surface of the percussion piston in such a way that the free percussion ram (38) is removed from the effective area of the percussion piston by a return spring (74) in the main percussion position. Under the effect of the return spring (74), said percussion ram is simultaneously supported on a gear member (64) of the percussion changing device (54), which projects with an extension (72) into the motion path of a stop surface (30) provided in the tool (18). The stop surface (30) reaches the extension (72) when it has moved away from the effective area of the percussion piston in an idle running state of the tool shaft (16). If said movement of the tool (18) is continued, the stop surface (30) impinges upon the gear member (64) against the effect of the return spring (74) and relocates the free percussion ram (38) in the effective area of the percussion piston by overcoming the spring force.

摘要： Disclosed is a safety coupling in a percussion hammer and/or drill hammer, comprising a basic sleeve (20), a driven toothed wheel (21) that is rotatably mounted on the basic sleeve (20) and can be driven by a drive unit, a closing ring (27) which is fastened to the basic sleeve (20), and a locking ring (28) located between the driven toothed wheel (21) and the closing ring (27). Said locking ring (28) is fixed in a torsion-proof manner relative to the closing ring (27) while being movable relative to the closing ring (27) in an axial direction, counter to the effect of a spring mechanism (29). The locking ring (28) is axially displaced while the driven toothed wheel (21) remains in the axial position thereof when a threshold torque is exceeded.

摘要： The invention relates to a wobble drive, in which a shaft (1) supports a wobble ring (8) by means of a pivot bearing (5), a finger (12) extending from said ring. To reduce vibrations caused by the movement of the finger (12), at least one balancing mass (20, 21) is configured on the shaft (1). Alternatively or in addition, at least one balancing mass (22, 23) can be provided on the wobble ring (8). This allows the vibrations that are caused naturally by the movement of the finger (12) to be compensated.

摘要： A percussion hammer drill and/or percussion hammer that can be guided by a handgrip (2) comprises a pneumatic spring striking mechanism with a reciprocating drive piston (11) and with a percussion piston (12) that can be operated by the drive piston. A cavity (13) for accommodating a pneumatic spring is provided between the drive piston (11) and the percussion piston (12). The cavity (13) can be connected to the surrounding area via a no-load operation channel (23, 24, 25) in order to achieve a no-load operation. To this end, a valve (19) is situated inside the no-load operation channel and can be controlled according to an application force that can be applied to the handgrip (2) by the operator.

摘要： A percussive mechanism, which is provided in the form of an, e.g. pneumatic spring percussive mechanism, comprises an electrodynamic linear drive, a drive piston (1), which can be reciprocally moved inside a percussive mechanism housing (9) by the linear drive, and a percussive piston (3). An additional hollow space (14, 17) is provided in front of and/or behind the drive piston (1) and can be isolated at least in part from the surrounding area so that a pneumatic spring can be created in the additional hollow space (14, 17). The pneumatic spring slows the drive piston (1) at its returning points and facilitates a returning motion without loading the electrodynamic linear drive.
