摘要:
The invention relates to a hand machine tool (2), particularly a percussion drill and/or percussion hammer, comprising a housing (4) having two parallel appendages (20, 22), a hollow, U-shaped, rounded handle (10) with a yoke (24) and two parallel legs (26, 28), said handle being movably supported on springs in relation to the housing (4) for the purpose of damping vibration. The appendages (20, 22) of the housing (4) extend into both hollow legs (26, 28) of the rounded handle (10). The invention also comprises two coupling elements (34, 36) situated in the hollow yoke (24) of the rounded handle (10) which serve to synchronize the movements of both legs (26, 28). The external end faces of the coupling elements (34, 36) are flexibly connected to the appendages (20, 22). The coupling elements (34, 36) are connected on the other end faces thereof to the rounded handle (10), and cross each other, and are flexibly connected to each other at the crossing point.

A hand-operated power tool (10), in particular a drill hammer and/or jackhammer, has a housing (11) which has a drive mechanism for driving a tool (12) that is receivable in a tool receptacle (13) and, in the rear region (14), remote from the tool receptacle (13), has a handle assembly (20) for grasping and handling that engages the housing (11). The handle assembly (20) is vibration-damped with respect to the housing (11), with the components contained in it, at least and substantially in the axial direction, by means of a vibration-damping device (FIG. 1).
摘要:
The invention is based on a hammer drill and/or chisel hammer, having an impact mechanism unit, an impact mechanism housing and at least one damping unit. The invention proposes that the damping unit is arranged on the impact mechanism housing along a main extension direction of the impact mechanism unit.
摘要:
The invention is a striking mechanism for a handheld power tools in particular electric hammer. A piston is arranged in an axially bidirectionally movable manner in a guide tube. A striker is provided which acts on a striking pin and which is held in a movable manner in the guide tube. A compression space is delimited by the piston and the striker such that an air cushion is enclosed therein. It is proposed that at least one spring element is provided between the striker and the striking pin.

The invention relates to a machine tool comprising an electric motor (2) which serves to drive a tool and which has an adjustable, electric brush arrangement (3), and comprising a mode selector switch (6) having various switch positions. Provision is made for an adjusting device (8) to displace the brush arrangement (3) as a function of the switch position of the mode selector switch (6). Furthermore, the invention relates to a corresponding method.
摘要:
The invention relates to a machine tool (2), in particular a hammer drill and/or percussion hammer, comprising a housing (4) and an at least partially hollow U-shaped bow-type handle (10) with a yoke part (24) and two parallel leg parts (26, 28), which are movably and resiliently supported with respect to the housing (4) for vibration damping, and also at least one coupling element (34, 36) for synchronizing movements of the two leg parts (26, 28), which is entirely or partially accommodated in the interior of the bow-type handle (10). It is provided that, in the vicinity of the coupling element (34), the bow-type handle (10) is provided with a switch (18), and that the coupling element (34) has a recess (58) for receiving a switch housing (64) of the switch (18) that protrudes into the interior of the bow-type handle (10).
