Problems solved by technology

[0018] The present invention provides a planetary gear support for an automatic transmission with an improved structure in order to solve the above-mentioned problems. A plurality of bridges that can be brazed and joined to the hub are arranged at intervals, thereby replacing the conventional deep drawing used for forming a cup shape and for joining the hub when it is suitable for sintering and brazing. Expensive processes such as electron beam welding used with the flange can be expected to save costs. By improving the structure of the welded part, the problem of deformation in conventional electron beam welding can be eliminated.

Embodiment Construction

[0031] The present invention will be described in detail below with reference to the accompanying drawings.

[0032] The present invention relates to a bracket for a planetary gear of an automatic transmission. In the bracket for a planetary gear of an automatic transmission, the hub part is not in the shape of a conventional cup but in the shape of a disk. A bridge is formed by brazing the lower surface of the hub portion to the upper surface of the bridge of the flange portion.

Abstract

The present invention relates to a carrier of a planetary gear set of an automatic transmission. In a carrier of a planetary gear set of an automatic transmission that includes a boss part having a spline in an inner surface of the center, and a flange part coupled with the boss part and supporting a pinion, there is provided a carrier of a planetary gear set of an automatic transmission that is characterized in that the portions of the boss part except for a center portion in which the spline is formed are formed in a circular plate shape, and a plurality of bridges are formed on an upper surface of the flange portion at regular intervals, and a lower surface of the boss part is blazing-coupled with an upper surface of the bridge of the flange part, and a pinion installation space is formed between the neighboring bridges.

Description

technical field [0001] The present invention relates to a bracket for a planetary gear of an automatic transmission, and more particularly relates to a bracket for a planetary gear of an automatic transmission whose structure has been improved. A plurality of bridges capable of brazing connection with the hub portion are installed at intervals. Background technique [0002] The power train of an automatic transmission vehicle is generally composed of a torque converter part that transmits the power of the engine to the transmission and a transmission used to obtain an appropriate rotational force. A damping clutch is installed in the torque converter part to Reduces power loss due to slippage of the torque converter unit. [0003] Here, the function of the transmission is to transmit the power from the engine to the drive shaft through the torque converter, and it consists of two or three sets of multi-plate clutches, a set of multi-plate brakes, a hand brake, a one-way clu...
