Embodiment Construction

[0026] The following description is of an exemplary nature only and is in no way intended to limit the invention, its application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0027] First, for a better understanding of the present invention, a conventional automatic transmission including a one-way clutch will be briefly described.

[0028] Such as Figure 6 As shown, the existing automatic transmission includes a plurality of planetary gear sets 1 to transmit power supplied from a vehicle drive source. The existing automatic transmission includes a one-way clutch 3 that prevents rotation in either direction of the planetary gear set 1 a of the plurality of planetary gear sets 1 , which is connected to the transmission input shaft 2 .

[0029] The one-way clutch 3 can prevent the planetary gear set 1a from rotating in either direction to prevent reverse power transmission ...

Abstract

The invention provides a gear support device of automatic transmission. The gear support device of automatic transmission reduces vibration and noise that are generated in a planetary gear set when power is transmitted from a vehicle driving source. In particular, the gear support device includes a gear support which is disposed on an outer peripheral surface of a hub retainer coupled to a planetary gear set directly connected to an input shaft of a transmission. The gear support rotatably supports the hub retainer by contacting with the outer peripheral surface of the hub retainer at every predetermined interval in a circumferential direction of the hub retainer.

Description

technical field [0001] The invention mainly relates to a gear supporting device of an automatic transmission. More particularly, the present invention relates to a gear support device of an automatic transmission that reduces vibration and noise generated in a planetary gear set when power is transmitted from a vehicle drive source. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] A transmission is a device that transmits power generated by a vehicle drive source such as an engine by appropriately converting the power into required torque according to a running state. An automatic transmission is a transmission in which the gears operate automatically according to the driving speed without manual operation by the driver. [0004] Generally, an automatic transmission includes a plurality of planetary gear sets to transmit power supplied from a vehic...
