Problems solved by technology

Therefore, for example, if the thickness of the element is increased to ensure sufficient strength of this part, then the efficiency of power transmission will be reduced, or noise will be generated
In addition, for example, if the above method (disclosed in Japanese Utility Model Patent Publication No. H05(1993)-14028) is applied to the portion where the innermost part of the lower side of the ear intersects the upper side end of the neck, then, in manufacturing The polishing process must be added to the work, which will increase the manufacturing cost of the component

Embodiment Construction

[0022] Now, preferred embodiments of the present invention will be described with reference to the accompanying drawings. figure 2 A belt constituting a continuously variable transmission according to the invention is shown. The belt 1 comprises two endless sheet-shaped endless belts 2 and a plurality of elements 3 arranged slidingly between the endless belts 2 adjacent to each other. Each endless belt 2 comprises a stacked plurality of sheet metal rings 21, which are annular and flexible.

[0023] Such as figure 1 As shown, element 3 includes an integrally formed body portion 31, head 32, and neck 33, which are punched from sheet metal (not shown). The body 31 is in contact with a pulley (not shown) of the continuously variable transmission, the head 32 is located above the body 31 , and the neck 33 connects the body 31 and the head 32 . The width of the neck 33 is smaller than the widths of the head 32 and the body 31 . In addition, a pair of saddles 34 are symmetrical...

Abstract

The invention provides a belt applied to a stepless speed changing transmission device, which comprises two girdle bands and a plurality of plate-like elements; wherein, a plurality of elements are arranged on the girdle bands and are able to slide; each element comprises a body by which the element contacts the pulley of a stepless speed changing transmission device, a head positioned on the top of the body, a neck with a width smaller than that of the body and the head and connecting the body to the head, two saddles respectively provided with the left-right upper ends of the body and two ears respectively provided with the left-right sides of the head and opposite to the saddles; the girdle bands are respectively held in the left-right accommodation spaces for girdle bands; each accommodation space for girdle bands is defined by the upper ends of the saddles, the side end of the neck and the bottom ends of the ears; each girdle band is provided with the saddles; a first concave is arranged at the innermost of the upper side of each saddle so that the first concave continues with the corresponding lower side of the neck; a second concave is arranged at the innermost of the lower side of each ear so that the second concave continues with the corresponding upper side of the neck.

Description

technical field [0001] This invention relates to belts for use in continuously variable transmissions for vehicles, and more particularly to the structure for the plurality of elements used to form such belts. Background technique [0002] Currently, various belt type continuously variable transmissions have been used for the transmission of vehicles such as automobiles. Typically, a conventional continuously variable transmission consists of two pulleys and a belt. Each pulley has a V-shaped cross-sectional groove extending circumferentially, one pulley is arranged on a rotating shaft and the other pulley is arranged on the other rotating shaft, and a belt having a V-shaped cross-section is arranged around these two pulleys, used to transmit power. The width of the circumferential grooves of the two pulleys is continuously inversely proportionally controlled to vary as the variable rate of the transmission is adjusted as power is being transmitted from one rotating shaft ...
