Definitions
- the invention relates to a one-way braking device according to the preamble of claim 1.
- Rotary attenuators usually have a braking rotor which is rotatably supported in a casing. There is a viscous fluid in the housing, e.g. silicone oil. When the rotor rotates a respective resistance is produced which makes itself felt as a braking torque. An interaction with a toothed rod or toothed segment which is mounted on the component to be braked becomes possible via a shaft led out of the housing. The shaft has mostly seated thereon a pinion.
- Such rotary attenuators exist in most varied embodiments. They are employed, above all, in automobiles, electronic devices and the like. They have relatively small dimensions.
- the freewheel is formed between the housing of the rotary braking device and another housing which receives the first housing.
- the first housing is floatingly received in the chamber of the second housing and the circumference of the first housing and a portion of the wall of the second chamber are formed such that a positive interengagement takes place between these portions if they are moved against each other because of a linear force component acting between these portions.
- a force acting on the pinion of the braking device is braked by means of the braking rotor.
- the first and second housings are acted on in a way that they get under a force opposed to the first force component the first housing can freely rotate in the second chamber of the second housing. Freewheeling is established for this case.
- the positive interengagement between the first and second housings allows to transmit a large torque. In contrast, the torque is approximately zero in the freewheel direction.
- a circumference of the first housing has a toothing and the second chamber has a toothed segment, the toothing and the toothed segment getting in engagement with each other in a braking operation and getting out of engagement in a freewheeling operation.
- the locking portion is defined by spaced locking edges which cooperate with the preferably cup-shaped or grooveshaped recesses at the circular circumference of the first casing.
- the circumference of the first housing is a polygon in section and the locking portion is shaped as a complementary polygonal portion.
- a positive interengagement is obtained also here when the first and second housings are pulled towards each other in such a way that the first housing gets into engagement with the locking portion of the second housing.
- the attenuator of the invention is symmetric freewheeling may be obtained in either direction in different mounting situations.
- a braking device is provided which is independent on the direction in which a braking torque or freewheeling is to be produced.
- only one series of tools needs to be manufactured to produce the parts of the inventive braking device which are preferably made of a plastic material.
- Another advantage is that the assembly of the braking device may be fully automatic. This makes unnecessary any manual preassembly as has been required for former one-way rotary brakes.
- the size of construction of the inventive braking device is random and, in particular, may be built to be very small.
- the material for the braking rotor and casing may be the same and preferably is a plastic. This also reduces the expenditure for the inventive braking device.
- FIG. 1 schematically shows a first embodiment of a braking device according to the invention.
- FIG. 2 schematically shows a second embodiment of a braking device according to the invention.
- FIG. 3 Schematically shows a third embodiment of a braking device according to the invention.
- FIG. 4 shows a section through the representation of FIG. 3 along line 4 - 4 .
- FIGS. 5 - 8 show the braking device of FIG. 4 at different stages of assembly.
- FIGS. 1 through 3 schematically show three rotary attenuators which respectively have a housing 10 a , 10 b , 10 c with diametrically opposed flanges 12 , 14 to be fixed to a substrate.
- the housings 10 a through 10 c respectively have an internal chamber 16 a , 16 b , 16 c .
- the chamber respectively has disposed therein a second housing 18 a , 18 b , 18 c.
- the outer circumference of the casing 18 a is configured as a polygon.
- the outer circumference of the casing 18 b is circular and is formed with groove-shaped indentations 20 at the circumference.
- the circumference of the casing 18 c is circular and is provided with a toothing 22 .
- the wall of the chamber 16 a is formed with a complementary polygon of the casing 18 a over a certain area at 24 .
- the chamber 16 b has an extension 26 by which two locking edges 28 and 30 are defined at the ends of the extension 26 , as viewed in a circumferential direction.
- the wall of the chamber 16 c has a toothed portion 32 .
- FIG. 4 is intended to be a section through the representation of FIG. 3, but could also represent a section through FIGS. 1 and 2.
- the flange portions 12 , 14 form part of a component 34 of the housing 10 c which has a lower plate 36 and an annular portion 38 .
- Plate 36 and annular portion 38 define the chamber 16 c .
- the annular portion 38 has put thereon a cap 40 which forms a snapping connection along with the outer side of the annular portion as can be seen at 42 .
- the top wall of the cap 40 has a central aperture 44 .
- the housing 18 c has a first portion 46 and a second portion 48 which are introduced into each other and are appropriately connected to each other.
- the housing 18 c has formed therein a chamber 48 which accommodates a braking rotor 50 which is rotatably and sealedly supported by a shaft butt end 52 in the housing portion 46 .
- the shaft butt end extends to the outside of the housing 10 c through an opening 44 and the outer portion of the shaft butt end 52 has seated thereon a pinion 54 .
- a braking action appears if the chamber 38 is filled with a viscous liquid, e.g. silicone oil. This action is generally known for rotary attenuators up to this point.
- FIGS. 1 through 3 It is evident from FIGS. 1 through 3 that a positive interengagement can be established, for instance, between the housings 10 a and 18 a in FIG. 1 and prevents a relative rotation between the housings when the housing 18 a is moved towards portion 24 . In this case, a torque applied to the pinion 54 is braked in a known manner. On the contrary, if the housing 18 a is moved to the opposite direction a free rotation may occur between casings 10 a and 18 a , which results in freewheeling if a torque is applied to the pinion 54 .
- the rotary attenuator of FIG. 2 reacts similarly.
- the positive interengagement is established with the indentations 16 b by the locking edges 28 and 30 .
- the positive interengagement is established between the toothing 22 of the housing 18 c and the toothed portion 32 of the housing 10 c.
- the effect described presupposes that, apart from a torque applied to the pinion, a linear force component will act on the housing 18 a to 18 c which either establishes or eliminates the positive interengagement described. This is the case, for instance, if a toothed rod engages the pinion 54 as is described in the context of FIGS. 5 through 8. It further presupposes that the housing 18 a , 18 b , and 18 c is floatingly received each in the chamber 18 a , 18 b , and 18 c of the housing 10 a , 10 b , 10 c , respectively.
- FIGS. 5 through 8 illustrate the rotary brake 30 d in a way approximately similar to that of FIG. 2 in different positions.
- a toothed rod 22 a is disposed below a pinion 40 d and a braking effect will result when the toothed rod 22 d moves to the right, and a freewheeling effect will result when it moves to the left.
- the housing of FIG. 6 is disposed as that of FIG. 5, but the toothed rod 22 d is disposed above the pinion 40 d .
- a rightward movement of the toothed rod 22 d again results in braking and a leftward movement results in freewheeling.
- the housing 32 d is turned through 180°.
- a rightward movement of the toothed rod 22 d of FIG. 7 which is disposed above results in freewheeling and a leftward movement results in braking.
- the toothed rod 22 d of FIG. 8 which is disposed below causes a freewheeling effect when moved to the right and causes braking when moved to the left.
