Summary of the invention
The object of the present invention is to provide transmission component work, that have the mechanical stepless transmission of middle flexible element under a kind of dry type state, it is stepless change transmission dry type composite metal band assembly, it is a characteristic with the pushing-type transmission, have higher transmission capacity and can be under the oil-free lubrication state characteristics such as proper functioning.
Technological scheme of the present invention is as follows:
A kind of stepless change transmission dry type composite metal band assembly, it has the both sides trough of belt by several (normally hundreds of) and the friction plate of the combination that overlaps each other and be pressed into two associative rings that in its groove the friction plate of overlapping combination are connected in series and form, described associative ring is to be combined by interior ring, outer shroud and middle multilayer closed loop metal tape, and outer shroud, interior ring contact with the upper and lower internal surface of friction film trap respectively.
Multilayer closed loop metal tape of the present invention is made by Maraging steel, is that " the no gap " of closely contact cooperates between each layer, and metal tape thickness is 0.18～0.2mm, and the metal tape number of plies is 3～12 layers.
The composite wear-resisting, low coefficient of friction of ring and outer shroud employing dry-type working is made in of the present invention, as engineering plastics etc.
Friction plate of the present invention has coaxial projection and groove along overlapping combinations of directions both sides, the projection and the groove of adjacent friction plate match, join end to end, locate each other, the Position Design of projection and groove is in the near place of trying one's best from oscillation center, with the loss of reducing friction, friction plate is made by material wear-resisting, high coefficient of friction, as the material that adopts technologies such as powder metallurgy to make.
The gearing principle of the dry type composite metal band assembly that stepless change transmission of the present invention is adopted is: dry type composite metal band assembly of the present invention is clipped in the middle of two pairs of awl dishes, frictional force between friction plate and the awl dish promotes to be passed to by the mantle dish by the initiative taper dish by friction plate successively, with this transmitting torque and motion, open with closing by the opening and closing of every pair of awl dish of mobile realization of the Moving plate of two pairs of awl dishes, finish continuously changing the friction radius of clean-up and change velocity ratio, thereby realize the stepless change transmission.
Adopt said structure, the present invention had the following advantages:
1, dry type stepless change transmission of the present invention adopts the composite of low coefficient of friction that metal tape and friction plate are separated with composite metal band assembly, reduces friction therebetween; And friction plate is made by the high material of friction factor, friction transferring power by friction plate and awl dish, frictional force between friction plate and the awl dish, promote successively to pass to by the mantle dish by friction plate by the initiative taper dish, therefore it is compared with the V-type adhesive tape that is used for dry type stepless change transmission at present, has higher transmission capacity and efficient; Compare with the metal tape assembly that is used for wet type (oil lubrication state) stepless change transmission at present and to have higher friction factor, it is much smaller to transmit the required axial force of same moment of torsion, thereby the moment of torsion with transmission is big, efficient is high, the life-span is long, the advantage that designs simplification, cost reduce.
2, the present invention is a characteristic with the pushing-type transmission, have higher transmission capacity and can be under the oil-free lubrication state characteristics such as proper functioning, be used for stepless change transmission (CVT) system of automobile, have tangible price advantage; Stepless change transmission (CVT) system that is used for motorcycle has the advantage of tangible transmission capacity and efficient.
