Description
Technical field
It is espespecially a kind of to provide unidirectional delivery torque applied to dynamic power machine the invention relates to a kind of swing brake
One-way rotating brake structural improvement, the frictional resistance when reducing rotation brake.
Background technique
At present one-way rotating brake mainly have ratchet-type 60, elastic-friction formula 70 with frictional 80 3 kinds of magnetic:
As shown in Figure 1, its for a ratchet-type 60 be using setting multiple springs 62 in a mandrel 61, will be same with those normalities
Multiple ratchets 63 of quantity push a ratchet 64 to, and 63 blocking ratchet 64 of ratchet drives when 61 1 direction of mandrel being enable to rotate, another
The spring of 63 compressed spring 62 of ratchet is dallied in each ratchet 64 when direction rotates；Above-mentioned ratchet-type 60 each 63 quilt of ratchet when idle running
A spring 62 pushes the resistance that ratchet 64 generates many bounces to.
As shown in Fig. 2, its elastic-friction formula 70 be used on a bearer ring 71 multiple 72 normalities of spring are set will be same
Multiple friction members 73 of quantity push a mandrel 74 to, make 73 displacement compression spring 72 of friction member when the rotation of a direction and cooperate mandrel
74 rotate and dally, and the cooperation of friction member 73 is reversed when other direction rotates is released by spring 72, and then is blocked simultaneously with friction member 73
Gu bearer ring 71 and mandrel 74 generate drive；When idle running between friction member 73 and mandrel 74, this respectively rubs above-mentioned elastic-friction formula 70
Part 73 is wiped between by each spring 72 promotion center roller 74 and bearer ring 71 and generates many elastic resistances.
The resistance of resistance and rolling that above-mentioned each spring 62,72 is beated designs, and will increase one-way rotating brake idle running
Resistance, such as: when being installed in bicycle, coasting distance when bicycle does not tread on can be greatly decreased in the resistance of the idle running, therefore
It such as can be reduced the resistance of the bounce or the resistance of rolling, when riding bicycle, identical distance will be more labor-saving.
For another shown in Fig. 3,4 figures and Fig. 5, magnetic frictional 80 is the multiple clips of upper setting for being used in a bearer ring 81
A magnet 83 is arranged in slot 82, each 82 bottom of clamping groove, and a friction member 84 is arranged in each clamping groove 82 and supplies the magnet 83
83 normality of multiple magnet of magnetic positioning, the above-mentioned setting attracts each friction member 84 toward a mandrel 85；As 81 side of a bearer ring
It is slid on magnet 83 to friction member 84 when rotation and cooperates mandrel 85 to rotate and dally；When bearer ring 81 is rotated toward other direction
When friction member 84 returned with rotation direction by 83 magnetic of magnet, and then bearer ring 81 and mandrel 85 are fixed simultaneously with friction member 84 and produced
Green tape is dynamic；The above-mentioned meeting of friction member 84 center roller 85 generates a resistance when idle running, which is that each magnet 83 attracts each friction member 84
Magnetic resistance.
By foregoing embodiments it is found that each ratchet 63 that the mandrel 61 of ratchet-type 60 interlocks ratchet 64 is required to identical number
The spring 62 of amount；Each friction member 73 that the mandrel 74 of elastic-friction formula 70 interlocks bearer ring 71 is required to the spring of identical quantity
72；Each friction member 84 that the mandrel 85 of magnetic frictional 80 interlocks bearer ring 81 is required to the magnet 83 of identical quantity；This is every
One spring 62,72 and each magnet 83 are generating a resistance for idling conditions Shi Junhui center roller 61,74,85, which can subtract
Coasting distance when few bicycle does not tread on, it may thus be appreciated that the fewer resistance of quantity that the spring 62,72 or magnet 83 are arranged is smaller,
And spring 62,72 or magnet 83 are the ratchet 63 or friction member 73,84 for cooperating identical quantity, ratchet 63 or friction member 73,84
Quantity is again related with torsion, and more multipotency generation torsion is stronger, must just sacrifice part torsion to reduce the frictional resistance of idle running,
Therefore the present invention the frictional resistance for reducing idle running with but can increase the torsion of gearing.Ratchet design torsion deficiency meeting structure collapses
Bad, friction member design torsion deficiency can generate skidding.
Summary of the invention
In view of prior art one-way rotating brake, have the frictional resistance of idle running big, is collapsed with torsion deficiency meeting structure
Bad or torsion deficiency can generate the shortcomings that skidding can not be interlocked normally, be inquired into many ways with being the idea thought and created
After studying sampling test, and multiple amendment improvement, release eventually of the invention.
The present invention provides a kind of one-way rotating brake of low friction resistance, includes: a swing brake ontology, multiple rollings
Column, two gearing ring plates and an at least playback means；The swing brake ontology has an inner ring surface and two sides, the inner ring
The multiple tanks for cooperating each roller of face interval circular row, and the tank has a fastening end and a disengaging end, the card of the fastening end
Depth processed is less than the disengaging depth at the disengaging end；The two sides of the another swing brake ontology are respectively equipped with an annular groove；It is multiple
Rolling member is placed in each tank of the swing brake ontology, can be displaced between the fastening end and the disengaging end, the rolling member
There is a diameter for column, which is greater than the blocking depth of the fastening end of the swing brake ontology tank, is less than the rotation system
The disengaging depth at the disengaging end of dynamic device ontology tank, and the rolling member opposite end is respectively provided with a spacing projection；This two gearings
Ring plate is respectively arranged at the annular groove of the two sides of the swing brake ontology, this two gearing ring plates simultaneously can produce an angle
Rotation, the interlock ring on piece are equipped with multiple gearing holes, which is greater than the spacing projection and is less than the diameter of the rolling member, and
Spacing projection is arranged in the gearing hole, and when the gearing ring plate being made to generate angular turn, which is synchronized to drive.
The quantity of the playback means be less than multiple roller quantity, for by this two gearing ring plate normalities by the disengaging end
It pushes away toward the fastening end, with a small number of playback means by most rolling member synchronously controls.
The one-way rotating brake main purpose of low friction resistance of the present invention drives two interlock rings with a playback means
Piece, then interlock multiple rolling members with two gearing ring plates and reach synchronization action, but it is without the use of with increasing the quantity of the rolling member
The spring or magnet of other equal amounts, can be greatly reduced the frictional resistance of idle running, but can increase rolling member quantity and set
Set increase torsion.
