Gearbox with uninterrupted shifting torque and shifting method

Abstract

The present invention relates to a gearbox and a shifting method with uninterrupted shifting torque, aiming to solve the problem that the existing AMT needs to remove gears, adjust speed, and engage gears when shifting gears, so that there is no power output when the gear is in neutral. technical problem. The gearbox includes a gearbox case, an input shaft, an intermediate shaft, an output shaft, an input gear, N gear teeth sleeved on the output shaft, and N+1 intermediate gears arranged on the intermediate shaft, where N is greater than or equal to A positive integer of 1, and also includes N+1 shift mechanisms corresponding to the input gear and N gear gears one by one; The friction plate and multiple friction plates are arranged at intervals; the driving device pushes the clamping assembly to move, thereby pushing the friction plate to move axially, so that the friction plate and the counter plate are clamped or disengaged. The invention also proposes a gear shifting method of the gearbox, which utilizes the frictional state of the friction plate and the dual plate to realize uninterrupted torque when shifting gears.

Description

technical field [0001] The invention relates to a gearbox, in particular to a gearbox with uninterrupted shift torque and a shift method. Background technique [0002] Automated Mechanical Transmission (AMT) is improved on the basis of traditional manual transmission, which not only has the advantages of automatic transmission, but also retains the high transmission efficiency, low cost and structure of manual transmission gear. Simple and easy to manufacture features. Usually, a manual gearbox adopts a synchronizer structure. When a gearbox with a synchronizer is shifted, the synchronizer must first be taken back to neutral from the previous gear, and then the synchronizer will synchronize the speed difference between the previous gear and the target gear. Implement shifting. The AMT gearbox part adopts a sliding sleeve structure. When the sliding sleeve structure shifts gears, it needs to return to neutral gear first, and then the engine or electric motor must be used to...
