Abstract
The utility model discloses a Hy-Vo silent chain for a transfer case. The Hy-Vo silent chain comprises an outer meshing working chain plate, an inner-outer composite meshing working chain plate and a guide plate which are connected through a hinge pin, wherein each of the outer meshing working chain plate and the inner-outer composite meshing working chain plate is provided with two teeth, the outer tooth profile of each tooth is straight, the inner tooth profile of each tooth is arc, and the curvature of each inner tooth profile arc of the inner-outer composite meshing working chain plate is larger than that of the outer meshing working chain plate. According to the Hy-Vo silent chain for the transfer case, advantages of both an outer meshing silent chain and an inner-outer composite meshing silent chain are combined, to be specific, the positioning is stable, the polygon effect is reduced, impact, vibration and noise are reduced, and the transmission efficiency is improved.
Description
Technical field
The utility model belongs to the Transmitted chains technical field, is specifically related to a kind of transfer case Hy-Vo silent chain of novel outer gearing+interior-outer compound engagement mesh mechanism.
Background technique
Silent chain just more and more widely be applied to engine art such as automobile, motorcycle, using more silent chain at present is round pin formula outer gearing silent chain and interior-outer compound engaging tooth shape chain, these two kinds of silent chains are to carry out engagement driving by the work carrier bar of silent chain and the involute of sprocket teeth, and are all littler than roller chain and bushing chain noise.The outer gearing silent chain is the silent chain with outside flank profil and the sprocket teeth Contact Transmission of carrier bar, and characteristics are positioning stablities of outside flank profil and sprocket teeth, but owing to finish instantaneous the engagement location, thereby polygon effect is serious, impact greatly, noise is big, and wearing and tearing are big; Interior-outer compound engaging tooth shape chain is that with outer gearing silent chain difference the inboard evagination flank profil of its work carrier bar at first contacts with the gear teeth in the sprocket engagement process, along with constantly engaging-in with the gear teeth, transferring outside straight-side profile to by inboard evagination flank profil gradually contacts with the gear teeth, until last realization outer gearing location, interior-outer compound mesh mechanism more is applicable to the high speed transmission than outer gearing mechanism, reduced polygon effect, and impact, noise etc.
Summary of the invention
In order to overcome the above-mentioned technical problem that the prior art field exists, the purpose of this utility model is, a kind of transfer case Hy-Vo silent chain is provided, and impact shock is little, and noise is low, has effectively improved wear-resisting property and transmission efficiency.
The transfer case that the utility model provides Hy-Vo silent chain, it comprises outer gearing work carrier bar, interior-outer compound joggleword carrier bar and guide plate, the three links together by bearing pin; Described outer gearing work carrier bar and interior-outer compound joggleword carrier bar all have 2 teeth, and the outside flank profil of 2 teeth is straight line, and inboard flank profil is circular arc; In described-curvature of the inboard flank profil circular arc of outer compound joggleword carrier bar is greater than the curvature of the wide circular arc of outer gearing work carrier bar inner tines; Transfer case comprises in some groups of outer gearing work carrier bars and some groups-outer compound joggleword carrier bars with the Hy-Vo silent chain, in every outer gearing work carrier bar and every-be equipped with mounting hole on the outer compound joggleword carrier bar; Described guide plate is provided with the guide plate hole, and the profile in guide plate hole is identical with the cross section profile of bearing pin.
The transfer case that the utility model provides Hy-Vo silent chain, its beneficial effect is, arrange assembling in certain sequence by the carrier bar of outer gearing mechanism and the carrier bar of interior-outer compound mesh mechanism, characteristics with outer gearing silent chain positioning stablity, in having simultaneously-outer compound engaging tooth shape chain impact shock is little, the characteristics that noise is low, realized the transmission of silent chain ekaconjugation, reduce shock and vibration, reduced noise, improved its wear-resisting property and transmission efficiency.

Embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the transfer case that the utility model is provided is described in detail with the Hy-Vo silent chain.
Embodiment
With reference to Fig. 1-Fig. 6, the transfer case of present embodiment Hy-Vo silent chain, it comprises outer gearing work carrier bar 1, interior-outer compound joggleword carrier bar 2 and guide plate 3, the three links together by bearing pin 4; It is straight line that described outer gearing work carrier bar 1 and interior-outer compound joggleword carrier bar 2 all have the outside flank profil of 8,2 teeth 8 of 2 teeth, and inboard flank profil is circular arc; In described-curvature of the inboard flank profil circular arc of outer compound joggleword carrier bar is greater than the curvature of the wide circular arc of outer gearing work carrier bar inner tines; Transfer case comprises in some groups of outer gearing work carrier bars 1 and some groups-outer compound joggleword carrier bars 2 with the Hy-Vo silent chain, in every outer gearing work carrier bar 1 and every-be equipped with mounting hole 6 on the outer compound joggleword carrier bar 2; Described guide plate 3 is provided with guide plate hole 7, and the profile in guide plate hole 7 is identical with the cross section profile of bearing pin 4.
With total joint number be 74 the joint silent chains be that example is described in detail, the total joint number of silent chain is 74 joints, namely formed by 74 chain links, the permutation and combination form of these 74 chain links is: in an exclusive joggleword carrier bar+three rows-and outer compound joggleword carrier bar, so carry out after 18 circulations, add 2 again and arrange interior-outer compound joggleword carrier bar, by bearing pin and guide plate, these 74 carrier bars are fitted together; During the transfer case running, outer gearing work carrier bar 1 and interior-outer compound joggleword carrier bar 2 alternately carry out engagement driving with sprocket wheel 5.
Use the utility model transfer case to have the advantage of outer gearing silent chain and interior-outer compound engaging tooth shape chain concurrently with the Hy-Vo silent chain: positioning stablity, reduced polygon effect, reduced shock and vibration, reduced noise, improved transmission efficiency.Transfer case Hy-Vo silent chain, the permutation and combination of all right conversion outer gearing work carrier bar and interior-outer compound joggleword carrier bar, satisfy the performance requirement of different transfer cases under different operating modes and client's individual demand, thus realize efficient under the transmission of variable load speed change, steadily, the function of low noise and high abrasion.
