Embodiment Construction

[0015] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0016] Figure 1 is a schematic structural diagram of an electromechanical automatic transmission with five gears and an auxiliary clutch. It is equipped with an auxiliary clutch 9 at the rear end of the input shaft 3 of the traditional electromechanical automatic transmission, and has corresponding auxiliary clutches. Clutch control mechanism 1, auxiliary clutch 9 is connected with the high gear transmission, and is combined or separated under the control of auxiliary clutch control mechanism 1, auxiliary clutch control mechanism 1 is electrically connected with TCU, and other structures are the same as the traditional AMT (including the The gear position control mechanism 2 that controls the gear position through the fork lever extending into the box outside the body, the input shaft speed sensor 6 installed on the box body co...

Abstract

The invention relates to an AMT transmission with assisted clutch, comprising manual gearbox, shift control mechanism, starting clutch and the control mechanism, speed sensor of inputting shaft, speed sensor of outputting shaft, shifting position sensor and control cell TCU. It is characterized in that assisted clutch and the control mechanism are set on the inputting shaft and the assisted clutch combines with high-shift gear. By the invention the problem that in shifting process the power of engine can not be transferred to wheels so that power is off is solved. There is no distinct deceleration in shifting and shifting comfort is improved. Good power property and shifting stability of vehicles are guaranteed while oil economy is improved and oil consumption in shifting is decreased.

Description

technical field [0001] The invention relates to a power transmission speed change device of a walking machine, in particular to a mechanical automatic transmission (AMT) device suitable for automobiles. Background technique [0002] Among the existing automobile transmissions, the traditional manual transmission (MT) mainly relies on gear transmission, which has high transmission efficiency and low cost, but it must rely on the driver to judge the shift point and manually shift the gear. The shift operation is due to the driver's shift technology The discrepancy may result in inaccuracy, sluggishness, etc., and increases the driver's workload. Electromechanical automatic transmission (AMT) is a traditional manual transmission with an electronic control system and an electronically controlled actuator. It is also a gear transmission, so the transmission efficiency is high, and automatic gear shifting is achieved. Therefore, the operation is simple and the structure is simple....
