Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problem that the existing AMT requires the process of shifting gear-governing-gear, so that there is no power output when the gear is in neutral. The gear shifting method, on the basis of maintaining the advantages of the existing double countershaft gearbox, can achieve the effect of uninterrupted torque when shifting gears

Embodiment Construction

[0038] In order to illustrate the technical solution of the present invention more clearly, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] The present invention proposes a new type of gearbox structure for commercial vehicles. By changing the structure of the output shaft assembly, the existing synchronizer or sliding sleeve structure is changed to a multi-plate friction plate structure, and a clamping assembly and a cylinder are added. Take the 4-speed gearbox as an example, such as figure 1 As shown, the gearbox includes input shaft 1, gearbox case 2, intermediate shaft 3, cylinder 4, clamping assembly 5, output shaft 6, 1st gear 7, friction plate 8, 2nd gear 9, dual plates 10, 3 Speed ​​gear 11, 4th speed gear 12 and cylindrical roller bearing 13. Wherein, the shaft end on the right side of the input shaft 1 has a blind hole, and the output shaft 6 is inserted into the blind hole of t...

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...
