Abstract
The utility model belongs to the technical field of automobile components, and particularly relates to a transmission shaft assembly applied to yoke type and rope wheel type manual glass lifters. The transmission shaft assembly is characterized in that the drive end at the lower side of a transmission shaft is provided with a lower shaft sleeve matched with the drive end, the lower shaft sleeve is fixed to a brake cover and made of polyformaldehyde, the positioning end on the upper side of the transmission shaft is provided with an upper shaft sleeve matched with the positioning end, and the upper shaft sleeve is fixed to an installing plate and made of polyformaldehyde. Thus, the transmission shaft assembly has the advantages of being reasonable in structure, small in friction loss, free of noise and capable of prolonging the service life of the glass lifters.
Description
Technical field:
The utility model belongs to technical field of automobile parts, is specifically related to a kind of transmission shaft component being applied on fork arm type equal, cable pulley type Manual glass lifter.
Background technology:
At present, the transmission shaft component of existing Manual glass lifter is all steel contact structures, the drive end diameter of axle of power transmission shaft directly coordinates with the axis hole of going out on brake cover, the positioning end diameter of axle also directly coordinates with the positioning shaft hole of going out on installing plate, between power transmission shaft and axis hole, produce direct metal rotation friction, the circularity of the flange axis hole of punching press on brake cover and installing plate, aperture size is difficult to control, the burr at punching edge is also uncontrollable, the burr easy damaged transmission diameter of axle, and between metal and metal, spin friction loss is larger, application life is short, also easily produce friction noise, if for a long time need not, easily produce corrosion, while re-using, corrosion point more aggravates frictional dissipation, cause frictional force excessive, thereby increase the rotation torque of controlling handgrip, reduce the application life of glass-frame riser.
Summary of the invention:
The purpose of this utility model is to provide a kind of rational in infrastructure, and frictional dissipation is few, and noiselessness can improve the transmission shaft component in the application life of glass-frame riser.
The technical solution of the utility model is: a kind of transmission shaft component, be provided with driven wheel, be provided with at brake cover inner chamber the tripping spring matching with brake block and linkage board and form by the drive block being provided with in the middle of power transmission shaft, power transmission shaft, the linkage board, the linkage board that match with drive block, it is characterized in that: be provided with the Lower shaft sleeve that the material on brake cover is polyformaldehyde that is fixed on matching with it at the drive end of power transmission shaft downside, be provided with the Upper shaft sleeve that the material on installing plate is polyformaldehyde that is fixed on matching with it at the positioning end of power transmission shaft upside.
Owing to adopting technique scheme, Upper shaft sleeve and the Lower shaft sleeve of the injection mo(u)lding that to have increased material on power transmission shaft be polyformaldehyde, the loss of spin friction and the noise of generation between metal and metal are avoided, and the axis hole circularity of Upper shaft sleeve and Lower shaft sleeve and size are easy to control, thereby have ensured coordinating between axle sleeve and power transmission shaft, reduce the rotation torque of controlling handgrip, thereby have rational in infrastructure, frictional dissipation is few, and noiselessness can improve the advantage in the application life of glass-frame riser.
Brief description of the drawings:
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further details.
Accompanying drawing is structural representation of the present utility model.
Detailed description of the invention:
With reference to accompanying drawing, a kind of transmission shaft component, be provided with driven wheel 4, be provided with at brake cover 6 inner chambers the tripping spring 7 matching with brake block and linkage board and form by the drive block 2 being provided with in the middle of power transmission shaft 1, power transmission shaft, the linkage board 3, the linkage board that match with drive block, be provided with the Lower shaft sleeve 8 that the material on brake cover 6 is polyformaldehyde that is fixed on matching with it at the drive end of power transmission shaft 1 downside, be provided with the Upper shaft sleeve 9 that the material on installing plate 5 is polyformaldehyde that is fixed on matching with it at the positioning end of power transmission shaft 1 upside.
