Problems solved by technology

However, when the gear that needs to be switched is not in the ready state, the shift time is relatively long, which is the so-called "shift hesitation phenomenon", and in some cases even exceeds 1 second, which makes the shift quality and driving experience reduced comfort
In addition, the jitter, frustration and even transmission protection of the dual-clutch automatic transmission may occur due to the fact that the vehicle often stops and starts due to road congestion, so that the clutch is often in a semi-linkage state, causing premature wear of the clutch plate and semi-linkage. caused by high temperature

Embodiment Construction

[0012] Embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0013] Such as figure 1 Shown, a kind of three-clutch automatic transmission, has: clutch (1), transmission output shaft (2), transmission gear (3), coupling device (4) and coupling body (5), it is characterized in that: described clutch ( 1) There are three clutches, that is, the first clutch (8), the second clutch (9), and the third clutch (10). The shafts corresponding to the above three clutches include the first clutch shaft (11), the second clutch shaft The shaft (12), the third clutch shaft (13), the first clutch shaft (11) and the second clutch shaft (12) are hollow shafts, and the second clutch shaft (12) is sleeved between the third clutch shaft (13) Outside, the first clutch shaft (11) is sleeved outside the second clutch shaft (12), and transmissions are distributed on the first clutch shaft (11), the second clutch shaft (12) and the third clu...

Abstract

A three-clutch automatic speed changer comprises a clutch, a transmission output shaft, transmission gears, a linkage device and a linkage body. The three-clutch automatic speed changer is characterized in that the clutch is composed of three clutch bodies including the first clutch body, the second clutch body and the third clutch body; according to the distribution character of the various gearsof transmission gears on three clutch shafts, except the lowest gear, the highest gear and the reverse gear, each work gear of each clutch shaft is provided with two preparing gears arranged on the other two clutch shafts correspondingly, wherein one preparing gear is higher than the work gear by one level, and the other preparing gear is lower than the work gear by one level. The three-clutch automatic speed changer has the beneficial effects that the phenomenon of gear shifting delaying like double-clutch speed changers cannot happen; and when the road jams, the high temperature and abrasion of the clutch can be relieved.

Description

Technical field [0001] The invention relates to a three-clutch automatic transmission, which belongs to the technical field of mechanical transmission, in particular to a three-clutch automatic transmission for road vehicles. Background technique [0002] Compared with the traditional planetary gear automatic transmission, the current dual-clutch automatic transmission is more conducive to improving fuel economy, and the fuel consumption can be reduced by about 15%. There is virtually no loss of torque during gear changes, and upshifts are astonishingly fast at a staggering 8 milliseconds when the upper gear is already in reserve. However, when the gear that needs to be switched is not in the ready state, the shift time is relatively long, which is the so-called "shift hesitation phenomenon", and in some cases even exceeds 1 second, which makes the shift quality and driving experience Comfort is reduced. In addition, the jitter, frustration and even transmission protection...
