Abstract: A continuously variable transmission has a continuously variable unit in the form of a variable belt drive and a pair of interconnected planetary gear sets arranged in differential drive relation between the transmission input shaft and the transmission output shaft. One of the planetary gear sets is connected with the input shaft, the output shaft and the output shaft of the belt drive. The other planetary gear set is connected with the input shaft, the output shaft and the input shaft of the belt drive. The overall transmission ratio is controlled between limits established in the continuously variable unit. The ratio is varied within a continuously variable range by varying the belt ratio.

Abstract: A pulley and "V" belt drive arrangement has a flexible belt disposed to transmit drive forces between two spaced "V" groove pulleys. The flexible belt is constructed from a single fan-folded metal strip which is maintained in a continuous loop by one or more continuous metal bands. The bands are disposed in a U-shaped saddle or slot area formed in the fan-folded belt. The sidewalls of the saddle prevent lateral migration of the bands. The band length is sized to provide a compression load on the fan-folded belt to prevent longitudinal separation of the ends of the belt during torque transmission between the pulleys.

Abstract: A V-belt (11) formed from a successive series of novel link elements (10). Each link element (10) has a body portion (20) which presents laterally spaced, beveled side wall (21 and 22). The body portion (20) includes first and second plate-like portions (28 and 29). Each plate-like portion (28 and 29) has first and second end surfaces (30,31 and 32,33, respectively). The second plate-like portion (29) overlies the first plate-like portion (28) and is longitudinally disposed with respect thereto such that the first end surface (32) of the second plate-like portion (29) is disposed in general proximity to the second end surface (31) of the first plate-like portion (28). A hook (35) extends vertically upwardly from the first plate-like portion (28) in proximity to the first end surface (30) thereof. An aperture (46) penetrates the second plate-like portion (29) to define a draw bar (48) in proximity to the second end surface (33) of the second plate-like portion (29).

Abstract: A multi-speed power transmission has an input shaft and a coaxially aligned output shaft. Each shaft has gearing members connected thereto. The input gearing drives an idler gear which, in turn, drives a ratio gear. A plurality of meshing ratio and idler gears rotatably supported on parallel shafts are serially driven from the input gearing. The shaft supporting each ratio gear has a selectively engageable clutch mechanism for selectively connecting the respective ratio gear shaft with an output gear member. The respective output gear members are in constant mesh with the output gearing member.

Abstract: A push-type metal V-belt for use with V-grooved pulleys is produced with a single formed and fan-folded strip of sheet metal. The folded strip has alternately tight-folded and open-folded portions having less height when viewed edgewise of the open-folded portions. During the forming of the strip, adjacent drive edges are formed so that when folded, these edges are aligned so as to become drive surfaces of the belt. When viewed in a lateral section, the drive surfaces are the outer edges of a substantially trapezoidal surface. Also, during the forming of the strip, a plurality of lateral slots are formed to provide an area or space for housing a plurality of metal bands which maintain the fan-folded strip in a continuous belt or loop configuration.

Abstract: A push-type metal V-belt is formed from a single strip of sheet metal. The strip is formed and folded such that the lateral faces between the converging outer drive edges are tapered to have a reduced thickness at the inner fold. The formed strip also has lateral slots in which, after folding, continuous metal bands are disposed for maintaining the belt in a continuous loop configuration.

Abstract: A friction drive chain for use with V-groove pulleys has a plurality of drive blocks mounted on a core strand. The core strand is comprised of a plurality of pivotally connected cylindrical core members. The drive blocks are secured to respective core members by centrally located retention clips which are disposed in an inner groove in each block and an outer groove in each core member. The clips also provide the drive connection between respective drive blocks and the core members.

Abstract: A flexible drive belt is comprised of a plurality of drive blocks which are assembled in a continuous loop by a plurality of tension bands extending between adjacent blocks. Each drive block has a pair of linear drive surfaces for transmitting drive forces along the straight span of the loop while being maintained in compression loading and a pair of rotary drive surfaces which frictionally engage conical surfaces of pulley members for converting the linear drive force to a rotary drive force by traversing the curved portion of the loop. Adjacent drive blocks are maintained in contact by the tension bands which operate through convex surface blocks disposed in concave surfaces formed on the drive blocks. These cooperating surfaces allow relative movement between respective drive blocks and convex surface blocks to permit the drive blocks to remain in abutment while traversing the curved portion of the continuous loop.

Abstract: The drive belt has one or more continuous metal bands which slidably support a plurality of drive blocks. Each drive block has a transverse arcuate surface having a radius dimension substantially equal to or 1% less than a transverse radius formed in the metal band. Each drive block also has an opening which facilitates band assembly. The opening is outwardly diverging and terminates inwardly in a slot at the transverse arcuate surface. The opening permits flexing of the metal bands during assembly of the metal bands and the drive blocks without exceeding the yield stress of the metal bands. The inner slot provides a retaining mechanism for the metal bands after assembly.
