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, which can be reciprocally moved inside a percussive mechanism housing by the linear drive, and a percussive piston. An additional hollow space is provided in front of and/or behind the drive piston 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. The pneumatic spring slows the drive piston at its returning points and facilitates a returning motion without loading the electrodynamic linear drive.

摘要： A boring and/or percussion hammer comprises an electrodynamic linear drive and a pneumatically damped percussion mechanism which is provided with a drive piston driven by the linear drive during the reciprocating movement thereof, an impact piston and a pneumatic spring arranged between the drive and impact pistons. An air-supply device comprises a pumping element, which is linearly forth and back movable for generating airflow. The pumping element is connected to the drive piston in such a way that the movement thereof is transmitted to said pumping element, thereby the cooling air is transported by an air channel for cooling heat generated elements.

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

摘要： A handle for a drill- and/or chisel hammer has a mount which can be fixed to the hammer. A radial grip is fixed to said mount, the grip axis of said radial grip crossing a tool axis which is defined by the position of a tool received by the hammer. A tangential grip is also fixed to the mount. Said tangential grip has a first grip section whose grip axis is tangential to the tool axis and a second grip section whose grip axis is tangential to the tool axis and essentially perpendicular to the grip axis of the first grip section.

摘要： The invention relates to a guiding cart for a manually guided tool, for example an abrasive cut-off machine, which comprises a movable frame on which a first and a second locating recess for inserting the abrasive cut-off machine are provided. A locking device is assigned to the first recess by means of which forces can be applied to the abrasive cut-off machine in the direction of the first locating recess and the second locating recess. In this way the abrasive cut-off machine can be reliably and rapidly fixed to the guiding cart after it has been inserted into the locating recesses. The insertion of the abrasive cut-off machine is facilitated by inclined inserting elements situated in the locating recesses.

摘要： A drilling and/or percussive hammer comprises a handle (10) and a hammer housing (1), which can move relative to the handle (10) and inside of which, among other things, a pneumatic spring percussive mechanism (4) is housed. The pneumatic spring of the pneumatic spring percussive mechanism (4) can be ventilated via a no-load operation duct (13, 15, 17, 26, 27) that is opened and closed by a valve (16, 17, 25). The valve (16, 17, 25) can be opened and closed according to a pressing force acting upon the handle (10). A delay device (18, 20, 21, 29, 30) controls the valve (16, 17, 25) during closing so that the valve reaches the position corresponding to the detected pressing force only with a time delay. This causes a smooth transition from the no-load operation to the percussive operation.

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

摘要： The invention relates to a pneumatic percussive tool for a paving breaker and/or a hammer drill comprising a drive piston which is displaceable both backwards and forwards by a crankshaft and arranged in a percussion piston which is displaceable both backwards and forwards. A hollow chamber is connected to a compensating chamber by an idling air channel and embodied between the drive piston and the percussion piston in order to receive a pneumatic spring. A valve is arranged in the idling air channel, the opening and closing position thereof depending on the rotational speed of the crankshaft. If the rotational speed of the crankshaft falls below a predetermined value, the valve opens the connection between the hollow chamber and the compensating chamber so that a pneumatic spring can no longer be to embodied in the hollow chamber and the pneumatic percussion tool is placed in a idling position.

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 which can move along a limited axial path straight into a main percussion direction. In a free percussion mode, the percussion piston indirectly impinges upon a percussion changing device, and by means thereof upon the tool, in a free percussion direction opposite to the main percussion direction. The impact surface of a tool shaft and the impact surface of a free percussion ram are placed opposite an impact surface of the percussion piston in such a way that the free percussion ram is removed from the effective area of the percussion piston by a return spring in the main percussion position. Under the effect of the return spring, the percussion ram is simultaneously supported on a gear member of the percussion changing device, which projects with an extension into the motion path of a stop surface provided in the tool. The stop surface reaches the extension when it has moved away from the effective area of the percussion piston in an idle running state of the tool shaft. If the movement of the tool is continued, the stop surface impinges upon the gear member against the effect of the return spring and relocates the free percussion ram in the effective area of the percussion piston by overcoming the spring force.
摘要翻译：本发明涉及一种爆破锤和/或锤钻，其包括具有冲击活塞轴向前后运动的冲击产生装置。在主打击方式中，冲击活塞撞击可以沿有限的轴向路径直线移动到主打击方向的工具。在自由敲击模式中，冲击活塞以与主打击方向相反的自由冲击方向间接撞击打击乐器改变装置，并且借助于该打击乐器在工具上。工具轴的冲击表面和自由冲击冲击器的冲击表面与冲击活塞的冲击表面相对放置，使得自由冲击冲头由打击乐活塞的有效区域通过复位弹簧移除主打打击乐的地位。在复位弹簧的作用下，冲击锤同时支撑在冲击更换装置的齿轮构件上，该冲击装置延伸延伸到设置在工具中的止动表面的运动路径中。当其在工具轴的怠速运行状态下已经移动离开冲击活塞的有效区域时，止挡表面到达延伸部。如果工具的移动继续，则止动表面抵抗复位弹簧的作用撞击在齿轮构件上，并通过克服弹簧力将自由冲击冲头重新定位在冲击活塞的有效区域中。
