Description

The motorcycle one-way gear clutch

The utility model belongs to the motorcycle parts, specifically is a kind of motorcycle one-way gear clutch.

Now; problem of stepless speed-change motorcycle ubiquity of the various models that people use; motor still runs up when vehicle idling travels exactly; drive each parts running of vehicle; increase the load of motor; vehicle can't normally be slided; it is particularly outstanding that this phenomenon shows in the process of running at high speed; this just causes engine fuel consumption big; component wear is serious; thereby influence the working life of motor; at these problems; the designer make a big improvement to the motor output transmission; so that vehicle can effectively reduce the load to motor when sliding; reduce each machine members of motor; to play the purpose that prolongs engine life; as Chinese patent disclosed overrunning clutch on August 16th, 95; its ratchet is positioned at the inner ring of clutch; pawl disk is positioned at the outer ring of clutch; ratchet is installed on the pawl disk; and be pressed on the ratchet in advance by spring; 2 ratchets are set on the ratchet cover plate at least; 2 ratchets are set on the ratchet at least, and the angle a of ratchet and ratchet binding site should be leaning angle, and the precompression of spring should be greater than the gravity of ratchet; centrifugal force during less than 600 rev/mins of rotating speeds; simpler on this overrunning clutch structure, preferably resolving the stepless speed-change motorcycle sprocket transmission device can not independently slide, serious to engine scuffing; working life is short; carry out the defective of difficulty, but still there is ratchet serious wear in the using process in it, relies on centrifugal force to realize the separation of clutch; make clutch not thorough easily; not exclusively, increase the deficiency of rate of fault.

The purpose of this utility model is not change any structure of former car, vehicle can be slided when idling and do not increase the load of motor, provide a kind of simple in structure, compact, clutch fully, running steadily, rate of fault is low, prolongs the motor motorcycle one-way gear clutch in working life.

The utility model is achieved through the following technical solutions:

It is a kind of motorcycle one-way gear clutch, comprise external gear, internal gear, ball and ring washer, the outer rim symmetry processing ratchet of internal gear, in ratchet, connect the tooth that rises with pin, between tooth and the internal gear stage clip is installed rising, inner gear housing is contained in the inner ring of external gear, on the inner ring of external gear, have ratchet, be processed with ball slideway in ratchet root both sides, along the uniform ball of slideway, between the inside and outside gear in the ball outside retaining row is installed, the slideway on the external gear vertically imbeds in the wheel body, and the degree of depth is 1/5～1/4 of institute's installation code ball.

Slideway on the described external gear vertically imbeds in the wheel body, and the degree of depth is 1/4 of institute's installation code ball.

Described retaining is arranged peripheral section and is wedge, is one with the riveted joint of internal gear edge.

Be symmetrily processed with 3～5 ratchets on the described internal gear.

Be symmetrily processed with 3 ratchets on the described internal gear.

Be processed with 26～28 ratchets on the inner ring of described external gear.

Be processed with 28 ratchets on the inner ring of described external gear.

The form that each tooth that rises of ratchet on the described outer rim and symmetry tapers off links.

The helix angle of described external gear external tooth be 20 ° 39 '.

Descend the ratchet on the external gear inner ring asynchronous in working order with the interior tooth of installing that rises of internal gear ratchet, ratchet on the external gear has a top to be pressed together on the rise top of tooth of one of them internal gear all the time, in running order, and the tooth that rises on two other internal gear is in half stitching state, do not work structure that axle sleeve, retaining are arranged and internal gear is fixed as one.

The utility model is compared with prior art owing to descend the ratchet on the external gear inner ring asynchronous with the interior tooth of installing that rises of internal gear ratchet in working order, ratchet on the external gear has a top to be pressed together on the rise top of tooth of one of them internal gear all the time, in running order, and the tooth that rises on two other internal gear is in half stitching state, do not work, structure that axle sleeve, retaining are arranged and internal gear is fixed as one, so have the following advantages:

1, simple in structure, compact, rate of fault is low.

2, clutch is complete, running is steady.

Describe in further detail below in conjunction with accompanying drawing:

Fig. 1: the utility model embodiment cross-sectional view.

Fig. 2: the utility model embodiment cross-sectional view.

Fig. 3: the utility model embodiment inner gear structure schematic representation.

Fig. 4: the utility model embodiment ball slideway cross-sectional view.

Among the figure: 1 external gear, 2 retaining rows, 3 internal gears, 4 ratchets, 5 ball slideways, 6 balls, 7 rise tooth 8 stage clips, 9 ratchets

In use, this is taken turns on the final stage transmission shaft that is installed in motor, chain is mounted on the external tooth of external gear 1, when high engine speeds turns round, the tooth 7 that rises on the internal gear 3 ejects under the effect of stage clip 8, block the ratchet 4 chamfering end faces on external gear 1 inner ring, drive external gear 1 high speed rotating, thereby make chain drive vehicle to overtake, ratchet 4 is the profile of tooth at the certain inclination angle of band of prior art, when sliding when slowing down in the cruising process of vehicle, the inertia of vehicle driving makes chain drive external gear 1 and turns round in the same way with internal gear 3, when rotating speed is higher than the rotating speed of motor, 28 ratchets 4 on external gear 1 inner ring are successively along on the ratchet 7 in the ratchet 9 that presses to internal gear 3 symmetrical distributions along the angular direction, when the top of a ratchet 4 on the external gear 1 presses to the top of one of them tooth 7 that rises on the internal gear 3, these tooth 7 work of rising, two other tooth 7 that rises is by the ratchet on the external gear 14 step-like the depressing that taper off successively, be in half working state, in external gear 1 rotation process, to enter working state at any time, simultaneously, rotate with retaining row 2 and the ball slideway 5 that internal gear 3 is fixed as one on ball 6 edges that are inlaid in the ball slideway 5, when decomposing external gear 1 and rotating to the heavy load of internal gear 3, but do not drive engine rotation, thereby realize sliding of motorcycle transmission device, reduced each machine members of motor, because of the degree of depth of ball slideway 5 recessed embeddings with 1/5～1/4 of the standard ball diameter size of being laid, with 1/4 is best, like this, in about 1/4 of ball 6 imbeds for gear mass, its load that is born when rotating is just mainly born by external gear 1, thereby reduced 6 couples of retaining rows' 2 of ball extruding force, strengthened the location of 2 pairs of balls 6 of retaining row, fixation, and external gear 1 can be according to the difference of vehicle, its external tooth helix angle be processed into corresponding 20 ° 39 of former skiving wheel helix angle ', 6 °, 8 ° or other angle, wearing and tearing have so also been reduced to the couple gear chain, each is zero to have improved former car, the working life of parts, make prolong 50% the working life of stepless speed-change motorcycle, its fuel consumption reduces about 40%/hundred kilometer, also makes the normal implementation of vehicle more laborsaving.
