Abstract

The invention relates to an automatic gearbox and an assembling method thereof. The automatic gearbox comprises a main shell and a torque converter shell, and a middle partition plate is arranged between the main shell and the torque converter shell. The entire gearbox is divided into a main shell assembly, a torque converter shell assembly and a middle partition plate assembly. The three assemblies can be assembled at the same time, so that the assembling efficiency is greatly improved, and batch production on an assembling line can be facilitated. A gear drive assembly is fixed in the middle partition plate, then the middle partition plate is fixed on the main shell, the middle partition plate achieves the transition supporting function of a connecting link, and the assembling stability of the gear drive assembly is greatly improved. Adjusting gaskets are additionally arranged at a uniaxial shaft system, a two-axis shaft system and a three-axis shaft system, and the assembling precision is improved; the gearbox with the structure is convenient to maintain.

Description

technical field [0001] The invention relates to a gearbox, which is suitable for multi-speed automatic gearboxes, especially eight-speed automatic gearboxes. Specifically, it relates to an automatic gearbox and its assembly method, which belongs to the field of mechanical technology. Background technique [0002] The gearbox is one of the core components of the car and an important power transmission part in the car powertrain. The performance of the car gearbox directly affects the power, handling, comfort, safety, reliability and fuel economy of the vehicle. Its quality also reflects the quality of the vehicle, and is a key component directly related to the performance of the vehicle. [0003] The gearbox includes the main casing and the front casing. At present, the gearbox adopts the method of direct assembly from the bottom layer to the top layer. All parts are directly installed from the bottom layer of the gearbox main casing to the top layer. After all parts are asse...
