Problems solved by technology

As for the independent shift lever mechanism (ISR), because it needs to change the traditional gearbox structure, its cost is 5-10 times that of ordinary gearboxes, and it cannot form an industrial scale in China.

Embodiment 1

[0039] see Figure 6 , 7 , when the gearbox is idling (neutral), assuming that the rotational speed of the input shaft 100 (and the first gear input gear) is 1000 revolutions, according to the first gear ratio, the rotational speed of the first gear output gear is 200 revolutions, and the output shaft does not rotate. When starting in first gear, the first and second gear rings move to the left under the control of the shifting mechanism, and the first and second gear rings press against the first gear synchronizer, so that the first gear synchronizer (target gear synchronizer) starts the synchronization process. , the speed of the input shaft (and first gear input gear, first gear output gear) gradually decreases. In order to make the input shaft speed decrease faster, we use the third-gear synchronizer (or fourth-gear synchronizer), fifth-gear synchronizer, and reverse-gear synchronizer as participating gear synchronizers, so that the third-gear synchronizer (or fourth-gear...

Embodiment 2

[0045] see Figure 10 , 11 , when the car is moving forward, the gearbox is engaged in the fifth gear, assuming that the rotational speed of the input shaft 100 is 2000 rpm, according to the fifth gear ratio, the rotational speed of the fifth gear output gear and the output shaft is 2000 rpm, the fifth gear ring and The speed of the fifth gear input gear is also 2000 rpm. The speed of the fourth gear output gear is the same (2000 revolutions) as the output shaft, the speed of the fourth gear input gear is 4000 revolutions, and the speed of the third and fourth gear rings is the same (2000 revolutions) as the input shaft. When it is necessary to change from fifth gear (current gear) to fourth gear (target gear), refer to Figure 10 , the fifth gear ring moves to the right under the control of the shift operating mechanism (disengages the fifth gear), and the third and fourth gear rings move right under the control of the shift operating mechanism to press the fourth gear sync...

Abstract

The invention provides a quickly synchronized shifting method of a gearbox, which can effectively shorten the synchronous time and improve the shifting speed. According to the method, in the synchronous process of a target gear synchronizer and in order to change the rotating speed of an input shaft, at least one participative gear synchronizer carries out the synchronous process so as to participate in the synchronous process of the target gear synchronizer; after the target gear synchronizer completes the synchronous process, the participative gear synchronizer exits the synchronous process; the participative gear synchronizer simultaneously satisfies the following two conditions: the synchronization of the participative gear synchronizer enables the speed of the input shaft to change as expected; and the participative gear synchronizer can simultaneously work with the target gear synchronizer.

Description

technical field [0001] The invention relates to a gear shifting method of a gearbox, in particular to a fast synchronous gear shifting method of a gearbox. Background technique [0002] In the general shifting process of the existing automobile gearbox, the active part and the driven part of the gearbox are synchronized through a synchronizer of a single gear. Refer below Figure 1-5 To be specific. [0003] Figure 1-5 The gearbox shown is a 5-speed ordinary gearbox, and a gear input gear 11, a second gear input gear 21, a third and fourth gear seat 34, a fifth gear tooth seat 54, and a reverse gear input gear 61 are fixed on the input shaft 100. A third gear input gear 31, a fourth gear input gear 41, and a fifth gear input gear 51 are provided. There is a gear output gear 12, a second gear output gear 22, and a reverse gear output gear 62 on the output shaft 200, and a second gear tooth seat 14, a third gear output gear 32, a fourth gear output gear 42, and a fifth gear...
