Problems solved by technology

However, preparing new pinions is an obstacle to suppressing costs
In addition, when a new pinion is prepared, there are various kinds of pinions with different rigidities, and there is a possibility that the pinion may be incorrectly attached to the carrier.

Abstract

The invention provides a planetary carrier capable of suppressing the cost of the planetary carrier and adjusting the rigidity of the planetary carrier in accordance with the rigidity of a pinion. Theplanetary carrier (4) includes first and second support hole parts (35) and (42) that support a pinion shaft on which a pinion gear is provided from both sides in an axial direction. The planetary carrier includes a first holding member (20) and a second holding member (21) . The first holding member includes a connection end (32a) that extends in an axial direction toward a second holding memberand that is connected to and faces the second holding member. The second holding member includes a fragile part (43) formed on an end part in a circumferential direction in a region to which the connection end is connected.

Description

technical field [0001] The present invention relates to planetary gear carriers. Background technique [0002] For example, a planetary gear mechanism is used in a transmission of a motor vehicle, and among the planetary gear mechanisms, there is a structure in which a planetary carrier is composed of a carrier base and a carrier plate. Legs (bridges) are arranged at intervals along the circumferential direction of the carrier disc. The connecting ends of the legs are inserted into the mounting holes of the wheel frame base, and the connecting ends inserted into the mounting holes are welded to the wheel frame base from the opposite side of the wheel frame plate. As a result, the carrier plate is joined to the carrier base to assemble the planetary carrier. In the circumferential direction of the planetary gear carrier, a storage opening is formed between the leg parts, and a pinion gear is arranged in the storage opening. The pinion is rotatably supported by the carrier ...
