To provide a power transmission belt and a method of producing the same that allows lightweight elements to be produced at low cost and allows the durability to be sufficiently ensured, the power transmission belt (10) includes a plurality of elements (12A) each having both side end surface portions, a rocking edge portion (21) rockably engaged with either one of a pair of other elements (12P, 12F) neighboring the element, and a concave-convex engagement portion (22) engageable with the pair of other elements (12P, 12F), in which each of the elements (12A) has a plate-like portion (23), a first convex portion (24) projecting from one surface (23c) of the plate-like portion, and a second convex portion (25) projecting from the one surface (23c) of the plate-like portion (23) in a spaced relationship with the first convex portion (24) to constitute the rocking edge portion (21), and each of the elements (12A) is engaged with the pair of other elements (12P, 12F) so as to press against one another by the first convex portion (24) and the second convex portion (25).

Drive belt (3) provided with a band set (31) and with a number of transverse elements (32), each transverse element (32) being provided with a cut-out (33) for accommodating the band set (31), with a base part (34) in height direction extending below the cut-out (33), with a head part (36) in height direction extending above the cut-out (33) and with a neck part (35) connecting the base part (34) to the head part (36), the cut-out (33) being delimited in part by a saddle surface (42) of the base part (34). The saddle surface (42) is provided with at least one groove (50) between two, higher lying parts (p1; p2; p3) of the saddle surface (42).

A push belt (6) for a continuously variable transmission comprises transverse elements (10) of at least two different types, wherein the differences between the transverse elements (10) reside in a profile (24) which is present at pulley sheave contact surfaces (18) of the transverse elements (10). On the basis of the use of at least two different types of transverse elements (10) as mentioned, many advantages are achieved, including improved traction, reduction of wear, and noise reduction. The design of the profile (24) can be such that a pattern of voids (28) is created at a contact side of the push belt (6), which voids (28) are used for receiving oil. The pattern of voids (28) can be random, or not. In the latter case, it is possible to have a path (28) for discharging oil, extending along the contact side of the push belt (6).
摘要:
The invention concerns a drive belt comprising steel transverse elements, each transverse element provided with a recess accommodating a part of an endless carrier (31) of the drive belt, which endless carrier (31) is composed of a laminated set of radially stacked, steel rings (32), each ring (32) including a nitrided surface layer (50). At least the nitride layer (50) at the radially outwardly oriented surface (51) of the radially outermost ring (32-0) of the endless carrier (31) and/or at least the nitride layer (50) at the radially inwardly oriented surface (52) of the radially innermost ring (32-I) of the endless carrier (31) is thicker than the nitride layer (50) of the in-between rings (32-B) of the endless carrier (31).
摘要:
The invention provides for a drive belt (3) provided with an endless tensile means (31) and a multitude of relatively thin transverse elements (32) that are slideably mounted on the tensile means (31) oriented predominantly transversely thereto, that have a front main face (40) and a rear main face (41) mutually separated over a thickness of the element (32) and predominantly facing in the longitudinal direction of the drive belt (3) and that have two side faces (36) one provided on each lateral side of the element (32), whereby between each side face (36) and the said front main face (40) a respective front transition surface (42) is provided and whereby between each side face (36) and the rear main face (41) a respective rear transition surface (43) is provided, which front and rear transition surfaces (42, 43) are provided with a mutually different dimension.
摘要:
The invention provides for a method for manufacturing a push belt for a continuously variable transmission composed of a multitude of relatively thin transverse metal elements that are slidably incorporated on one or more laminated endless tensile means (5) that are each composed of a set of mutually nested flat metal rings (4). The method according to the invention comprises a step (VII*) of assembling the endless tensile means (5) from a number of previously calibrated metal rings (4) and a subsequent step (VIII-N) of nitriding the endless tensile means (5) as a whole.

The invention relates to a hybrid V-belt (4) having at least one traction support (2) and a plurality of blocks (6) arranged thereon and serving as support elements. The at least one traction support (2) is made of elastomer material and is reinforced with a cord ply (12). The surfaces of the traction support (2) are crossribbed or corrugated and are provided with a cover layer (14, 16). In order to enhance the fatigue strength of said hybrid V-belt, the die cord ply (12) is arranged directly in the 'lower' radially inner cover layer (14). This provides for direct contact between the cord ply (12) and the radially inner cover layer (14) in the area of the zeniths (6a, ...) of the 'lower' block slot flanks.
