Embodiment Construction

[0039] Hereinafter, the present invention will be described with reference to the drawings. First, Fig. 11 shows the situation in which the present invention is mounted on a V-belt type automatic transmission. The driven pulley mainly includes a movable pulley half body A, a fixed pulley half body 3 and a driven shaft 4 as shown in FIG. 11 . The movable sheave half A includes a hub member 1 and a movable sheave surface 2 .

[0040]As shown in FIGS. 3 and 4 , the hub member 1 includes a hub shaft portion 11 and a large-diameter cylindrical portion 12 formed on one end side of the hub shaft portion 11 in the axial direction. The large-diameter cylindrical portion 12 is formed in a substantially flat cylindrical shape, and is formed to have a larger diameter than the above-mentioned hub shaft portion 11 (see FIG. 4A ). Furthermore, the above-mentioned large-diameter cylindrical portion 12 is formed as a disc perpendicular to the axial direction of the above-mentioned hub member...

Abstract

A V-belt automatic shift pulley is provided, pulley surface can be mounted simply and quickly with respect to a hub shaft, and the combination is firm. Parts (1) forming the hub element comprise a hub shaft (11), a large-diameter circular cylinder part (12) disposed at one side terminal in the axial direction of the hub shaft (11), a step surface (14) formed between the hub shaft (11) and the large-diameter circular cylinder part (12), a groove formed in an axial direction at the peripheral lateral surface of the large-diameter circular cylinder part (12). A movable pulley surface (2) is formed, and a circular cylinder combination portion (22) is formed at the diameter center of the pulley surface (21). The circular cylinder combination portion (22) is inserted by the large-diameter circular cylinder part (12), and the wall shape of the circular cylinder combination portion (22) along said groove portion is riveted.

Description

technical field [0001] The present invention relates to a pulley of a V-belt automatic transmission. In the V-belt automatic transmission, the surface of the pulley can be easily and quickly installed relative to the hub shaft and the joint state can be made very firm. Background technique [0002] Patent Document 1 discloses that, in the manufacture of the pulley of the V-belt type automatic transmission, laser welding, plasma welding, etc. to integrate. Furthermore, Patent Document 2 discloses a structure in which a cylinder constituting a part of the oil chamber on the back side of the pulley is fixed to the back side of the movable pulley by caulking. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 10-103438 [0004] Patent Document 2: Japanese Unexamined Patent Publication No. 9-329208 [0005] First, in Patent Document 1, when manufacturing the pulley by welding the above-mentioned driven surface and the hub into one, in order to avoid deforma...
