(1) The method and the principle for judging the gear by the device are as follows:
as shown in fig. 1 and 2. A shaft sensor 4 is mounted to the housing 6, the shaft sensor 4 being aligned with the speed gear 5 on the intermediate shaft 2, the two being collinear in a direction perpendicular to the intermediate shaft 2, but with a distance between the shaft sensor 4 and the test gear 5. The output shaft sensor 7 is arranged on a bearing cover of the transmission and is aligned with the odometer rotor 8, and the odometer rotor 8 is sleeved on the output shaft 3. The invention utilizes any transmission gear 9 on the intermediate shaft 2 of the existing main box 61 as the speed measuring gear 5, and does not need to add an additional speed measuring gear 5, preferably, the sixth gear 16 is selected as the speed measuring gear 5.
The rotating speed directly measured by the shaft sensor 4 is the rotating speed W of the speed measuring gear 53The speed measuring gear 5 and the second gear 12 are on the same intermediate shaft 2, so that the rotating speed of the speed measuring gear 5 is the rotating speed of the second gear 12, and the second gear 12 and the first gear 11 are constant mesh gears, so that the rotating speed W of the shaft 1 can be calculated through the gear ratio1。
In particular, the method comprises the following steps of,
W1＝W3·I1； (1)
wherein I1 is a constant mesh gear ratio,
I1＝Z12/Z11 (2)
combining the formula (1) and the formula (2), the speed ratio C of the speed changer is as follows:
C＝W2/W1 (3)
wherein W2The actual gear of the gearbox can be obtained by measuring the rotating speed of the output shaft by an output shaft sensor 7 and comparing C with the calculated speed ratio of each gear.
When the engine drives a shaft 1 of the transmission to rotate, the shaft 1 drives an intermediate shaft 2 to rotate, a shaft sensor 4 is triggered, and the rotating speed of the shaft 1 is measured. When the speed changer is connected with a certain gear, the speed changer output shaft 3 is driven to rotate, the output shaft sensor 7 measures the rotating speed of the output shaft 3, and according to the rotating speed of the shaft 1 and the rotating speed of the output shaft 3 and the formula (3), the speed ratio C of the speed changer can be calculated to be W2/W1。
Since the transmission gear ratios can be calculated by the number of gear teeth engaged, the following equation (4) is used:
and through | C-inJudging if I is less than or equal to 0.3, and judging if the theoretical speed ratio of C to the speed changer is inIf the difference satisfies the formula (4), it can be determined that the transmission is actually in the n gear, n is 1, 2 … M gear, and M is the gear that can be engaged.
For example, when three gears are engaged, the theoretical gear is calculated by the following equation (5):
when i3 calculated by the following formula is compared with the measured C, and the difference is less than or equal to 0.3, it is determined that the third gear is engaged.
According to the transmission route diagram 4, the speed ratio calculation method of each gear of the gearbox comprises the following steps:
take 4 steps as an example: the gears participating in the transmission include a first gear 11, a second gear 12, a sixth gear 16, a fifth gear 15, a sixteenth gear 26, a seventeenth gear 27, a nineteenth gear 29, and an eighteenth gear 28.
4-gear speed ratio:
(2) the process of gear engaging prompt through the device is as follows:
taking the 12-gear asynchronous device transmission as an example, when the transmission is shifted up from 3-gear to 4-gear, the rotation speed W of the first sliding sleeve 30, the second sliding sleeve 31 and the third sliding sleeve 32 on the second shaft 9 can be calculated through the gear ratio of the tachometer gear 5 and the fifth gear 1530、W31、W32；
When the gear is engaged, the gear is shifted to neutral, the second sliding sleeve 31 is disengaged from the seventh gear 17, the rotating speed of the second sliding sleeve 31 is determined by the output shaft 3, and the second sliding sleeve W31And the rotational speed W of the seventh gear 1717The same can be obtained by the same method,
at this time, the rotational speed W of the fifth gear 1515Is a shaft rotating speed, therefore, the calculation method is as follows:
measuring the speed W from a sensor3、W2The rotational speeds of the shift sleeve 31 and the synchronized fifth gear 15 can be obtained from the expressions (7) and (8), since W is31、W15And the difference of the rotating speeds exists, and if the gear engagement time is not correct, gear engagement difficulty or gear engagement failure is inevitably generated.
When | W31-W15| ≦ 85 (9)
At this time, 4 gears are engaged, and gear beating cannot occur.
The optimal rotating speed difference for synchronizing the sliding sleeve and the synchronized gear is calculated in the gear-up operation through the formula (9), so that the optimal gear-shifting time can be found, the operation of a driver is facilitated, and the gear can be shifted easily.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
