Definitions

  • the invention relates to a freewheel ratchet device, in particular a ratchet wrench according to the preamble of claim 1, such as for actuating screw parts or - tools e.g. using a screw or screw socket place.
  • Such a ratchet device is described in WO 86/04008. It essentially consists of one at the same time serving as a handle part, in the interior a freewheel with inner and outer ring is provided.
  • the Freewheel outer ring is immovably fixed in the housing, while a shaft in the freewheel inner ring is torsion-proof, however is axially displaceable.
  • the shaft can have two outer Take up switching positions, where he then on one or other end of the housing with an output pin e.g. a hexagon nut is attachable, protrudes from the front. By shifting the shaft and Moving the entire tool becomes left-handed or right-handed Ratchet tool achieved. Switching this ratchet tool, without having to move the tool through 180 ° is not possible. A non-ratcheting, position not functioning as a normal screwdriver can be set.
  • the object of the invention is therefore a freewheel ratchet device specify the simple structure and simpler Handling switching the facility to at least two Operating positions (left and right active), three if possible Positions (additional blocking position) allowed.
  • the Driving section of the shaft is when switching with a of the two freewheels can be brought into engagement, depending on whether the Ratchet device should be left or right active.
  • the driving section is to achieve good power transmission to be interpreted in length so that it is almost, but at most the height of the freewheel is. So the switching path is at least equal to the length of the one-way clutches used to prevent unwanted jamming. This makes it switchable Ratchet mechanism achieved that is simple in construction and handling and switching to the opposite Active direction allows without having to implement the tool got to.
  • the switching movement can either by axial Moving the shaft between those in the ratchet body over their outer rings fixed freewheels or by axial Holding the shaft in the ratchet body and axial, common Moving the freewheels in relation to the shaft made be, so that if necessary one or the other Freewheel engages with the drive portion of the shaft brought.
  • Customary freewheels usually have one each Outer and an inner ring.
  • the Inner rings of the two freewheels and the driving section of the To coordinate formally in such a way that a non-rotatable but axially shiftable connection between them is obtained.
  • a particularly small, simple embodiment is obtained according to the invention by using freewheels, which do not have an inner ring, the driving section then the role of the inner ring takes over by a corresponding Profiling its outer surface.
  • the idler rollers are therefore based directly on the lateral surface of the driving section functionally.
  • a particularly cost-effective one in terms of manufacture and construction extremely simple embodiment is also obtained when as a driving section on the advice, a freewheel inner ring in a known manner e.g. by shrinking, pressing on or by radial pinning.
  • a commercial part in a simple manner on the corresponding smooth-cylindrical part of the shaft arranged without having to make a customized bearing profiling of the shaft must be carried out.
  • At least two switching positions can be assumed a left and a right active position.
  • three switching positions can also be implemented a left and a right active position and, in addition, an overall blockade of the ratchet movement Fixing position in which an inventive ratchet screwdriver then like a rigid, simple screwdriver works and is operated.
  • the switchover can be carried out by shifting the shaft at least two, preferably three, axial positions with the freewheels fixed in position in the housing.
  • the drive-side pin of the shaft protrudes in different lengths from the drive-side end face of the ratchet body.
  • either the pin on the output side can be gripped and pulled or pushed, or it can be on one on the drive side the shifting and sliding movements of the shaft projecting from the housing.
  • the definition of the switching positions is also in itself known indexing or blocking devices between the switching sleeve and ratchet body jacket easily realized. Since the Operating forces on this embodiment directly on the Switching sleeve must be applied are either for this a receiving opening in the center on the drive end provided for a corresponding tool, and / or the outer surface is by corrugation, plastic coating, etc. for direct Hand control equipped with good grip.
  • the drive side Cones in e.g. the square plug-in opening for the Tool operation must be kept accordingly.
  • the position fixing or switching can be done radially or secant through the ratchet body Linkage, such as spring-loaded slides, directly in shape or through interposed locking balls on the shaft or its elements act.
  • the shift linkage could also be below the lower, output side Be arranged freewheel and with the output pin, or corresponding grooves in this, cooperate. This is the considerable extension of the ratchet body no longer necessary on his drive-side body part, whereby a lower construction is achieved. adversely however, is that by introducing the two or three Switching grooves the cross-section of the output pin, the torque has to transmit, is weakened and thereby something is to be interpreted more vigorously.
  • the shift linkage or the shift slide can be in another Execution also leading radially between the two freewheels, interact directly with the shaft. It is e.g. a spacing over a washer of the two freewheels and in this space to pass the slide.
  • the shaft is then in a relatively short version, only with driving section and output side pin available, the slide for the two active positions in front of or behind the driver section and for a central blocking position in a central one Driving section groove engages.
  • the slider itself can via a spring-loaded, in the ratchet body on the long side recessed rocker arm with actuating pin, in each Position are held. A slight radial pressure on the actuating button moves the slide radially outwards, so that the shaft is released and axially into another position can be moved.
  • the blocking position with central position linkage not through central fixation the middle section, but by short, axial pushing be made towards the drive side so that the shaft with its corresponding end with the bottom wall the drive side of the ratchet body engages positively.
  • This can be achieved in that in the end face the shaft or a short upper pin of the shaft and in the corresponding wall of the ratchet body with each other corresponding gears are provided.
  • This can respective spur gears or on the pin and in the corresponding recess provided in the ratchet body wall Circumferential gears or grooves, which ensure a high, direct Torque transmission are to be interpreted.
  • a long drive side can be on the shaft Be provided, the length of which is designed so that the pin from the drive end of the ratchet body protrudes. This gives the opportunity to the drive end of the shaft with a tool directly act to transmit momentum. However, it can also be used with impacted on the face of the shaft without damaging the ratchet, which is great often becomes necessary.
  • the embodiment with immovable is particularly advantageous To view shaft and sliding freewheels.
  • the pin on the output side remains always at the same level, so that despite switching to left- or clockwise or blocked position always the same There is a feeling of work without the use of the tool Adjust yourself to a different tool length got to.
  • the switchover is also very easy to construct to execute and also to handle, since only a radial through a longitudinal slot and with the free-running rings connected sliding pin is to be arranged. Then this sliding pin on the output-side jacket end the lower or common freewheel outer ring, can be a very compact and easy to grip, at the same time simple switchable tool, especially if in addition, locking arrangements interacting with the sliding pin for the three switch positions.
  • each Slide part can be held pressed in an end position. If the locking device is released, then it is under spring pressure the ratchet is always pressed into the same active position. Against spring force must then in a first or second Position can be shifted to a blocking or counter-rotating Get asset position.
  • Ratchet mechanism is achieved when the Ratchet body made of two essentially identical sleeve or pot-shaped body parts in a mirror-image arrangement with the openings facing each other, forming the cylindrical interior between them. Are there the two parts of the body can be rotated and shifted together connected, practically a one-piece cylindrical-drisch hollow Forming ratchet body.
  • the ratchet body can advantageously be made from two Mirror-shaped, sleeve-shaped parts only from a sleeve-shaped part with attached to this on the front Be designed cover plate.
  • a ratchet body 1 which in axial Direction is divided approximately in the middle and thus from one upper, drive-side, sleeve-shaped body part 2 and one lower, output-side, also sleeve-shaped body part 3 is composed.
  • the two body parts 2 and 3 are essentially at least in relation to their outer shape identical in that they have a smooth cylindrical surface 4 and have two smooth, outer end faces 5 and 6, respectively.
  • In the inner space 9 thus formed are two freewheels 10 axially aligned, these freewheels 10 reversed are effective, i.e. one is left-handed and the other neurologicalratschend.
  • the freewheels 10 have corresponding Outer rings 11 on and on these supporting freewheel rollers 12, but no inner ring.
  • Coaxial, centric is one Shaft 15 arranged, the slightly thicker driving section 16 has, with its outer surface with the freewheel rollers 12 cooperates.
  • the driving section shows 16 has a profile 17 on its lateral surface that of a corresponding freewheel inner ring.
  • the shaft 15 has on both sides of its driving section 16 each a pin, namely an output side Pin 8 and a drive-side pin 18th
  • a switching and drive sleeve 19 is located above the body part 2 axially displaceable and rotatably attached at the same time, the the pin 18 of the shaft 15 fixed and at the same time holds rotatable.
  • Indexing devices not shown allow three switching positions of the switching and drive sleeve 19 or the shaft 15 with its driving section 16 e.g. an upper position for left turning, a lower one Right turn position and a central position to lock or blocking the ratchet.
  • a central square plug opening 7 is provided in from the outside the square pin of an actuator, e.g. a socket wrench can be inserted, to help apply greater torsional forces or an actuation extension to enable.
  • the drive-side pin with its outer end and is rotatable therein, but axially immovable attached.
  • this is drive-side housing part 2 formed axially enlarged so that despite a relatively long drive-side pin 18, this not out of the ratchet body even in the uppermost switch position protrudes from the front.
  • Via a radially guided shift linkage 20 the shift and position indexing is realized.
  • This shift linkage acts with corresponding grooves 21 on the pin 18 together.
  • the shaft 15 only has one driving section 16 here on that at one end the output side out of the ratchet body outstanding pin 8 has. In addition, they are two facing end faces of the body parts 2 and 3 axially spaced by an intermediate ring 22.
  • Shift linkage 20 a radial slide 23 is provided here, which has the driving section 16 with its inner end engages behind or engages in the central groove 21 blocking.
  • the slider 23 is on a rocker arm 24 with opposite operating button 25 moves, which in turn has a spring 26 from the surface of the body is kept slightly pushed out, thereby simultaneously the slider 23 remains in the engaged position. By pressing the operating button 25 against the force of Spring 26, the slide 23 is pulled out radially, the shaft releasing for an axial shift-slide movement.
  • Fig. 4 it can be seen that in one embodiment Similar to Fig. 3, the blocking positioning is not like in the previous embodiments by a central Position of the driving section 16, with simultaneous Intervention in both freewheels is realized, but through positive engagement of the drive shaft end in the bottom wall of the drive-side body part 2. For this are on the corresponding end face of the shaft 15 and in Teeth 27 introduced inside the bottom wall. To take the blocking position is thus the shaft 15 from its to move the upper active position further inwards, until the teeth 27 engage in each other accordingly. From the arrangement of those interacting with the shift linkage 20 Grooves 21 in the driving section 16 can be seen very well. Instead of the front teeth, however axially aligned sliding clutch teeth are also provided be on a corresponding drive-side pin, the in an end recess in the lateral surface recessed clutch toothing interacts, as from one recognizable further embodiment described below is.
  • FIG. 5 is the execution of the switching device or Shift linkage 20 as a spring-loaded slide 23 with an operating button 25 shown with a ball indexing ring 28 with indexing ball 29, a recess 30 in the slide 23 and of course the ring grooves 21 in the driving section 16 (see Fig. 4) interact.
  • the slide 23 is so moved that he with the recess 30 at the level of the ball 29th comes to a standstill. This allows the ball, which was previously in a the grooves 21 has clamped, radially into the recess 30 moved and so the shaft 15 released and axially be moved.
  • Fig. 6 shows a special external design of the embodiment 3 or 4 as a switchable ratchet wrench with square pin 14 on the shaft pin 8 and upper Square plug opening 7 in the housing or handle part 34.
  • One with dashed T-screwdriver 40 is inserted into the plug opening 7 via its square pin 14, thereby applying a higher torque can.
  • the shaft 15 has a driving section 16 has, on the outer surface of a freewheel profile 17 is introduced. It also has an output side Pin 8 and a drive-side pin 18.
  • Fig. 8 also allows the formation of the shaft 15 in relation on the surface profile 17 of its driver 16 and recognize the central arrangement of the output-side pin 8.
  • the shaft 15 is also axially displaceable in one piece here sleeve-shaped ratchet body 1 arranged. It's closed recognize that the ratchet body 1 overall significantly longer is designed than in the previous exemplary embodiments, it can be seen that in addition to the interior 9 for the Another interior 32 is provided to accommodate the two freewheels which is for receiving the driving section 16 in third, blocking position. So there are three Switching displacement paths of approximately the same length through the shaft 15 or its driving section 16 carried out.
  • the shaft 15 has a relatively long pin 18 on the drive side can be pushed axially through a through hole 33, with the outer end of the Pin 18 far over the drive end face 6 of the Ratchet body 1 protrudes, as by interrupted, thin Lines shown.
  • This Gears 27 are relatively long, so that a relatively high in the blocking position over the ratchet body 1 Torque can be applied to the shaft.
  • Figures 10 and 11 show another basic one Embodiment with switchable freewheels 10 and axially fixed shaft 15.
  • the ratchet body is 1 trained by a switching stroke longer than in the previously described embodiments.
