Intelligent AMT gearbox

Abstract

The invention discloses an intelligent AMT gearbox which mainly utilizes the prior AMT gearbox and arranges a planetary gear transmission system between a friction clutch and an engine crankshaft. The planetary gear transmission system mainly comprises a central gear, a planetary pinion carrier and a gear ring, wherein the central gear is coaxially connected with a driving friction plate, the planetary pinion carrier is coaxially connected with the crankshaft, the gear ring is meshed with a planetary gear, an a motor is arranged on the outer side of the gear ring, the motor shaft is provided with a motor gear meshed with the gear ring, and the rotating shaft of the central gear is provided with a locking mechanism. The gearbox also comprises a gearbox control unit TCU, an engine control unit (ECU), a motor control device, an engine speed sensor and a clutch speed sensor. While starting the gearbox, the motor is utilized to directly start the engine, thus omitting the traditional starter; and while in gear-shifting, the rotating speed of the motor is controlled to finally enable the rotating speed of the driving friction plate to be consistent with the rotating speed of the driven friction plate, thereby achieving the goal of stable gear shifting. The invention is suitable for high-grade and medium-grade sedans.

Description

technical field [0001] The invention relates to an automobile transmission, in particular to an automatic mechanical AMT transmission. Background technique [0002] At present, with the development of automobile manufacturing technology, many automobile transmissions with different performances have appeared, such as: fully mechanical transmission MT transmission, continuously variable CVT transmission, automatic mechanical AMT transmission and manual transmission, etc., while automatic The mechanical AMT transmission can best take into account cost, power and economy, but the impact problem of the AMT transmission when shifting gears cannot be effectively solved. The fundamental reason is that the friction clutch connected with the transmission The rotational speeds of its active friction plate and driven friction plate are inconsistent, and the defective that can produce impact during above-mentioned shifting has restricted the development of AMT speed changer.
