Problems solved by technology

Because AMT realizes the automatic shift function by integrating the shift control system and electronic control unit on the basis of manual transmission, it has a good inheritance, but the existing AMT adopts integrated control, so it cannot Excluded in time, the cost is high, the adaptability is poor, and they are all used in transmissions with fewer gears, which cannot meet the needs of the market and the requirements of vehicles for automatic transmissions

Abstract

The invention provides a twelve-gear electronic control mechanical type automatic transmission which comprises a six-gear main box, a two-gear subsidiary box, a clutch and an electronic control unit. By the adoption of a main and subsidiary box structure, electronic control gas drive structures are adopted in a gear shift execution mechanism of the main box and a gear shift execution mechanism of the subsidiary box, a gas source of a vehicle is fully utilized, increase of the cost is reduced, and meanwhile the reliability of a system can be improved; meanwhile, an electronic control pneumatic clutch control system is adopted, and therefore power transmission is controlled by fully utilizing the gas source of the vehicle and the character of large separating force of the clutch; in the whole electronic control pneumatic arrangement and connection processes, the modularization arrangement is adopted, different execution mechanisms and electronic control equipment are arranged nearby, signals are collected, fed back and sent to the different parts through lines, and corresponding operation is finished through control over a gas channel; the ability to adapt to and match with transmissions of different mechanical design structures is improved, repair and maintenance can be carried out specifically, the structure is simple, the cost is low, and controlling is convenient and direct to carry out.

Description

technical field [0001] The invention belongs to the technical field of transmissions, in particular to a twelve-speed electronically controlled mechanical automatic transmission. Background technique [0002] At present, there are many kinds of automobile transmissions, but they are mainly divided into two categories: manual transmission and automatic transmission. Although the structure of the manual transmission is simple and the price is relatively low, the driver's driving and manipulation are labor-intensive, which can easily lead to fatigue driving and affect driving safety. Automatic transmission simplifies driving operation, can improve driving safety, and also eliminates differences in fuel economy, power performance, emission performance and transmission system life caused by drivers of different levels. Therefore, automatic transmissions are very important to the current automotive market Urgent needs. Existing transmission basically comprises manual transmissio...
