The transmission can produce different speed ratios between engine and wheel during automobile driving, realizes the transmission of different gear rotating speeds, and is divided into manual and automatic types. The manual transmission is mainly composed of gear and rotating shaft, and produces speed change and torque change through different gear combinations. The automatic transmission AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, and achieves the purpose of speed change and torque change through hydraulic transmission and gear combination.
[0003] According to the planetary carrier disclosed in patent application No. CN201910145759.1, the planetary carrier includes a main planetary carrier and a planetary carrier end cover formed in two parts. The planetary carrier end cover includes an end cover body and a tooth portion located on the outer periphery of the end cover body. The axial thickness of the tooth portion is greater than the axial thickness of the end cover body. The tooth portion protrudes only in the axial direction of the end cover body towards the end face of the main planetary carrier. The planetary carrier end cover is connected with the main planetary carrier in a manner of interference fit, spline connection and / or welding to prevent relative rotation. The material strength of the planetary carrier end cover is higher than that of the main planetary carrier. The main planetary carrier is a cast part, and the planetary carrier end cover is a forged part. The main planetary carrier is composed of ductile cast iron, and the planetary carrier end cover is composed of low carbon steel.
[0004] The above technical solution has some defects in actual use.
