Definitions

  • the invention relates to a power tool with a mounted in a gear housing, multi-stage transmission and with a switching device for switching the transmission of a gear stage in another gear, the one spring-loaded, in several Switching stages can be brought slide switch and one, actuated by this, on an axial having displaceable ratchet wheel acting, resiliently formed switch bracket.
  • Power tools of the above type have, stored in a gear housing, Multi-stage transmission and a switching device for switching the transmission of a gear stage in another gear stage to the speed of one for the application reaching tool, such as a screwdriver bit or drill to the conditions adapt.
  • a power tool with a, mounted in a gear housing, multi-stage transmission and with a switching device for switching the transmission from one gear stage to another gear stage.
  • the transmission has a spring-loaded, can be brought into several stages shift slide and a, from this actuated resiliently acting on an axially displaceable ratchet wheel Switch bracket on.
  • a disadvantage of the known solution is that in a transmission with more than two gears several slide valves are necessary.
  • the present invention is based on the object, an economically producible and to create a handy multi-speed transmission.
  • the object is achieved in that the transmission has a plurality of axially displaceable Has switching wheels, each ratchet interacts with a shift bracket and the switch bracket can be actuated by means of the slide switch.
  • the gearbox has more than two courses. Furthermore, all switching elements can be actuated by the operation of the slide switch and thereby ensures a high degree of handiness.
  • By an axial displacement of the Shift valve is a switching of the transmission from one gear stage to another Gear stage safely ensured.
  • the spring-trained switch bracket ensure a Safe switching, especially when switching the gearbox at standstill, as the Shift bracket engage the corresponding parts of the transmission, at the latest at one Drive of the gearbox.
  • the switch brackets preferably each have one, fixedly arranged on the transmission housing, Swivel axis on to a defined switching position of the switching wheels and thus a reliable To ensure switching.
  • the transmission housing for leadership arranged the shift bracket bearing parts, in particular through holes, the area wise Recording the switch bracket.
  • each switch bracket each has at least one engagement part and at least a switching part for switching the corresponding switching wheel, wherein the engaging part interacts with the corresponding ratchet and the switching part as a transmission means the actuating force from the slide switch to the engaging part is used.
  • the slide switch preferably has at least one recess for supporting the switching part on, and thus ensures a compact design of the transmission. Moreover a recess is economical to produce and facilitates the final assembly of the transmission.
  • the recess is preferably transverse to the longitudinal axis of the transmission and substantially tangentially formed to the switching wheels through to a simple final assembly and ensure safe guidance of the switching part in the slide switch.
  • the recess advantageously has a control link for pivoting in the longitudinal direction the switch bracket to the pivot pocket on to a structurally simple and to ensure economic control of the switch bracket by the slide switch.
  • the Control link pivots depending on the position of the slide switch individual control arms and thereby shifts the corresponding to the respective switch bracket ratchet.
  • the switch bracket pass through the recess advantageously with their respective switching part, which acts as a connecting part.
  • the recess transverse to the longitudinal axis of the transmission preferably has a height which essentially corresponds to the diameter of the switching part with a game to an optimal To ensure switching.
  • the game allows in the manufacture of the transmission a higher tolerance and thereby has a positive economic effect on the production costs out.
  • the control link advantageously has two switching stages, wherein different and mutually corresponding switching stages are connected to each other by a ramp.
  • a transmission 1 of an inventive power tool is shown to the working direction A a tool holder 11 for receiving a tool holder, For example, a ringerb itfact connects.
  • the transmission 1 has a substantially cylindrical transmission housing 6, for example is made of plastic or the like, and a switching device for switching of the transmission 1 from one gear stage to another gear stage.
  • the Transmission 1 a spring-loaded, in three, in particular in Fig. 1a to 3a shown, Switching stages can be brought on switch slide 3 and a first and second switch bracket 5a, 5b, each acting on a corresponding axially displaceable ratchet wheel 4a, 4b.
  • a U-shaped switching bracket 5a, 5b is shown, which is a switching part 15 and two engagement members 14, wherein the two engagement members 14 each have free ends 14a of the switching bracket 5a, 5b form and the switching part 15, the two engaging parts 14 with each other combines.
  • the free end 14a of the engaging parts 14 is about 90 ° relative to the rest Angled engaging member 14, so that the free ends 14a of the switch bracket 5a, 5b against each other are directed and in each case a corresponding recess in the form of a Ring groove 4c on which the switching bracket 5a, 5b associated switching wheel 4a, 4b can be brought.
  • the two engagement parts 14 pass through the transmission housing 6 with their free ends 14a by respectively corresponding, diametrically arranged and axially extending Longitudinal holes 18.
  • the switching bracket 5a, 5b are resilient, for example made of spring steel or similar.
  • For pivotable mounting of the switching bracket 5a, 5b has the Transmission housing 6 two, provided with through holes, bearing elements 19a, 19b on which the switch bracket 5a, 5b pivotable about a pivot axis S on the transmission housing 6 store.
  • the switching bracket 5a, 5b pass through the switching part 15, respectively, the two corresponding through holes next to the slide switch 3rd
  • Fig. 6 substantially having a cuboid outer contour
  • Slide switch 3 is mounted axially displaceable on the transmission housing 6 and has a, transverse to the longitudinal axis L of the transmission 1 and substantially tangential to the switching wheels 4a, 4b continuously formed recess, in particular a control link 20.
  • the Control link 20 extends axially to the gear 1 and has at the two longitudinal ends respectively a taper 21 for storage on the transmission housing 6.
  • the switching bracket 5a, 5b pass through the control link 20 each with the switching member 15 and are in the control link 20th mounted pivotably relative to the pivot axis S.
  • control link 20 has two switching stages 22, 23, wherein different and mutually corresponding switching stages 22a, 23a by a Ramp 24a are interconnected.
  • the slide switch 3 at the of Gear housing 6 side facing away from an actuator 25 for the placement of the Slide valve 3 on.
  • the slide switch 3 By the slide switch 3, the transmission 1 between three different gears switchable.
  • the slide switch 3 is shown with the control slide 20, wherein the switching parts 15 are shown in cross-section to their positions in the control link 20 clearly in the three different courses.
  • the transmission 1 in first gear and the two shift yokes 5a, 5b are perpendicular to the longitudinal axis L. of the transmission 1, as can be seen in particular from Fig. 1b.
  • Fig. 2b is the Shift slide 3 in contrast to those in Fig. 1a and 1b in the direction of A moved shown and the transmission 1 in second gear.
  • transmission 1 has two, in the longitudinal direction L of the transmission 1, successively arranged planetary gear, as is known from the prior Technics are well known.
