Description
Technical field
The invention belongs to machinery fields, more particularly, to a kind of bicycle ratchet mechanism.
Background technique
Bicycle ratchet is cooperated using traditional pawl in existing technology, and pawl is inside by centrifugation
Power is cooperated, and pawl relies on external pressure to engage outside, but no matter it is any be all rigid cooperation be easy to produce it is larger
Abrasion, and pawl manufacture is difficult, while the junction of pawl will bear biggish shearing force, influence service life.
Summary of the invention
The object of the present invention is to provide a kind of structures ratchet mechanism simple, convenient and practical, securely, especially suitable pressure
The larger situation of power.
The technical scheme is that a kind of bicycle ratchet mechanism, including ratchet and pawl, the ratchet are cylinder
Through-hole is arranged in shape, ratchet center, and ratchet internal tooth is arranged in the side wall of ratchet through-hole, and one lateral tooth flank of ratchet internal tooth is inclined-plane, separately
One lateral tooth flank is cambered surface, one circle slideway of ratchet internal tooth middle position setting, ratchet surrounding setting threaded hole.
The pawl is a disk, and thickness is identical as ratchet, and a slide plate, the cunning is arranged in pawl side wall middle position
Plate thickness is identical as chute width, and through-hole is arranged in pawl center, and for pawl around setting pawl slot, the pawl slot is a rectangle
Groove, spring is provided in pawl slot, and pawl ball is arranged close to the position of pawl slot notch in spring.
The ratchet is made of two panels, and the threaded hole of two panels ratchet is bolted, and the slideway of ratchet passes through pawl
Slide plate slides connection, the spring are welded in pawl slot, and the spring other end and pawl ball are flexibly connected, the pawl ball and spine
Wheel rolls connection.
Further, the tooth of the ratchet internal tooth is continuously arranged.
Further, the groove size of each tooth of the ratchet internal tooth is identical as pawl ball size.
Further, the ratchet and pawl sideline parallel with axis is respectively provided with fillet.
The advantages and positive effects of the present invention are:
1, the pawl is set as a sphere, and manufacture is more easier, and can carry out to avoid rigid collision is generated
More firm and safety when cooperation, it is not easy to damage.
2, the pawl is cooperated by slideway and ratchet, is not needed tie point and is attached, and is effectively increased pair
The ability to bear of pressure.
3, the ratchet is two panels composition, facilitates and what maintenance install.
4, the pawl is made of multiple, is worked in coordination, even if there is partial destruction not influence function still.

Specific embodiment
It elaborates with reference to the accompanying drawing to the present invention.
As shown in figures 1 to 6.
The course of work of this example: a kind of bicycle ratchet mechanism, including ratchet 1 and pawl 2, the ratchet 1 are cylinder
Through-hole is arranged in shape, 1 center of ratchet, and ratchet internal tooth 6 is arranged in the side wall of 1 through-hole of ratchet, and 6 one lateral tooth flank of ratchet internal tooth is oblique
Face, another lateral tooth flank are cambered surface, 6 middle position of ratchet internal tooth setting, one circle slideway 7,1 surrounding of ratchet setting threaded hole 3.
The pawl 2 is a disk, and thickness is identical as ratchet 1, and a slide plate 9, institute is arranged in 2 side wall middle position of pawl
It states 9 thickness of slide plate and slideway 7 is of same size, through-hole is arranged in 2 center of pawl, and pawl 2 is around setting pawl slot 8, the pawl slot 8
For a rectangular recess, spring 7 is provided in pawl slot 8, pawl ball 4 is arranged close to the position of 8 notch of pawl slot in spring 7.
The ratchet 1 is made of two panels, and the threaded hole 3 of two panels ratchet 1 is bolted, and the slideway 7 of ratchet 1 passes through spine
The slide plate 9 of pawl 2 is slidably connected, and the spring 5 is welded in pawl slot 8, and 5 other end of spring and pawl ball 4 are flexibly connected, described
Pawl ball 4 and ratchet 1 roll connection.
The tooth of the ratchet internal tooth 6 is continuously arranged.
The groove size of each tooth of the ratchet internal tooth 6 is identical as 4 size of pawl ball.
The ratchet 1 and the sideline parallel with axis of pawl 2 are respectively provided with fillet.
Ratchet 1 and pawl 2 are installed when use, ratchet mechanism is installed on bicycle later, steps on foot pedal later
Pawl ball 4 will stick into ratchet internal tooth 6, so that it may drive bicycle to advance, pawl ball 4 and ratchet internal tooth 6 are to fix at this time
Connection, if opposite direction steps on foot pedal, pawl ball 4 will be deviate from from ratchet internal tooth 6, can not also be fixed later, at this time
Pawl ball 4 and ratchet internal tooth 6 are to roll connection.
One embodiment of the present invention has been described in detail above, but the content is only preferable implementation of the invention
Example, should not be considered as limiting the scope of the invention.It is all according to all the changes and improvements made by the present patent application range
Deng should still be within the scope of the patent of the present invention.
