Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Fig. 2 to Fig. 4, the utility model provides the novel column foot of a kind of bicycle rear-hub, and it comprises flower-drum body 1, ratchet sheet 2 and ratchet 3.
Flower-drum body 1 comprises the left and right two parts 11,12 be oppositely arranged, and connects and run through two-part axis 13.Any one in the two parts of described left and right is provided with the receiving space 10 for accommodating fixing described ratchet sheet 2 and part ratchet 3.The present embodiment is positioned on right half 12 for receiving space 10, and in fact, also can be arranged on left half 11, namely described ratchet sheet 2 and ratchet 3 can be positioned at the left side of flower-drum body 1.
As shown in Figure 5, one end of described ratchet sheet 2 is provided with positive stopper 21, described in deviate from positive stopper 21 side be provided with from ratchet sheet 2 to away from the outstanding cross buckle 22 in positive stopper 21 direction.During assembling, described cross buckle 22 is towards the internal direction of described flower-drum body.Accordingly, be provided with in described flower-drum body multiple for accommodating the groove 101 fixing this cross buckle.Like this, described cross buckle 22 and groove 101 are fixed, thus ensure that the fixing of ratchet sheet 2 and flower-drum body 1.Because cross buckle 22 compares firmly with the engaging of groove 101, can ensure not affect ratchet sheet 2 and the connection of flower-drum body when ratchet 3 relatively rotates with ratchet sheet 2, ensure that the reliability of product.Certainly, this is only one preferably embodiment, in other embodiments selectable, also can be described pawl seat and ratchet sheet be fixed sturcture, relative motion between flower-drum body and ratchet sheet, namely described negative stopper is arranged in flower-drum body, and positive stopper is arranged on ratchet sheet towards on the surface inside flower-drum body, also can implement.
As shown in Fig. 5 to Fig. 7, the pawl seat 32 that described ratchet 3 comprises tubular and the negative stopper 31 be arranged on pawl seat 32.Described pawl seat is set on described axis 13, and being partially housed in receiving space 10 of pawl seat 32.Described negative stopper 31 and the corresponding setting of positive stopper 21, the number of teeth is identical, and engages each other.As shown in Figure 4, each tooth of described stopper comprises the first surface 211 and second surface 212 that connect adjacent two teeth respectively.The slope of described first surface is greater than the slope of second surface, or the area of first surface is greater than the area of second surface.Namely described stopper entirety is tilted to second surface direction by first surface.Preferably, the tooth of described stopper is also provided with the transition face 213 connecting first surface 211 and second surface 212 further.Wherein, described first surface 211 is active exposure face, and described second surface is passive exposure face, and described transition face 213 is auxiliary plane.The present embodiment illustrates for positive stopper, in fact, also can be negative stopper, also just stopper and negative stopper can all adopt this kind of structure, or wherein one adopts this kind of structure, another adopts common gear or only arranges first surface and second surface, transition face is not set, all can realizes the utility model object, all within design of the present utility model, namely the structure of positive and negative stopper can be identical, also can be different.When positive and negative stopper all adopts this kind of structure, the first surface of positive stopper and negative stopper is contrary with the direction of second surface, namely the first surface of positive and negative stopper is relative with first surface, second surface said structure relative to second surface, the realization of one-way non-return function between ratchet sheet and ratchet can be ensured, when ratchet sheet positive movement relative to ratchet, be fixed between the second surface in described two passive exposure faces, described ratchet drives ratchet sheet to rotate, and then drives flower-drum body to rotate.When the counter motion relative to ratchet of ratchet sheet, the Contact of the first surface in described two active exposure faces, because first surface slope is comparatively large, can not produce engaging effect, and meeting relative dislocation to next tooth, and then produces non-return effect.In addition, by arranging transition face, can when counter motion, produce a power obliquely, the dislocation being convenient to ratchet sheet and ratchet is moved.Preferably, the number of teeth of described positive stopper and negative stopper is 3 to 150, adopts so close toothing, can ensure driving efficiency further and improve the reliability of product.
In the utility model, described ratchet and described flower-drum body are combined by magnetic absorption.Concrete, in described ratchet and described flower-drum body, any one is made for magnetic material, such as magnet.Certainly, also can two be that the relative magnetic material of polarity is made, also can one of them make for magnetic material, another is made for metallic material, such as iron, nickel etc., as long as magnetic absorption effect can be produced, all can reach the purpose of this utility model, belong to the utility model design.In addition, described flower-drum body or ratchet can be partly only also magnetic material or metallic material, as long as realize the effect of magnetic absorption, all can realize the utility model object.
According to another kind of embodiment of the present utility model, the novel column foot of described bicycle rear-hub, also be provided with two flat thin magnets further, one of them is arranged in flower-drum body, another is arranged on ratchet, in the present embodiment, described ratchet and/or flower-drum body are that non-magnetic material is made, such as aluminium etc.Described flat thin magnet both can be embedded wherein, also can for being sticked on its surface, by attracting each other between two flat thin magnets, also can produce adsorption, certainly, this is only one preferably embodiment, can select in other embodiments, also only can arrange flat thin magnet in a place, another place is set to metal, also can implement.
Owing to being due to magnet adsorption effect, when ratchet and ratchet sheet relative direction are moved, mutually stagger between positive and negative stopper, two parts can be made to realize of short duration separation, subsequently due to magnetic absorption, can again be attached together again, like this, the function of traditional non-return structure can be realized, and the life-span of product can be ensured, decrease the parts such as spring, maximum possible reduces the aging speed of product.
The utility model adopts the stopper arranging close toothing, and realizes check function by magnetic absorption, changes the non-return mode that tradition is fixing, decreases number of parts, effectively reduce cost, improve driving efficiency and product reliability.
