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 As shown, a three-clutch parallel shaft output automatic transmission is equipped with: a clutch (1), a transmission output shaft (2), a transmission gear (3), a coupling device (4) and a coupling body (5), and is characterized in that: The clutch (1) is composed of three clutches, namely the first clutch (8), the second clutch (9), and the third clutch (10), and the shaft corresponding to the above three clutches has the first clutch shaft (11) , the second clutch 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 on the third clutch shaft (13), the first clutch shaft (11) is sleeved outside the second clutch shaft (12), and the first clutch shaft (11), the second clutch shaft (12) and the third clutch shaft (13) Ther...

Abstract

A triple-clutch parallel-shaft-output automatic transmission comprises a clutch, a transmission output shaft, transmission gears, a coupling device and a coupler. The clutch includes three clutches, namely, first clutch, a second clutch and a third clutch; the distribution of the transmission gears on the three clutch shafts feature: in addition to a lowest gear, a highest gear and a reverse gear,each working gear of each clutch shaft having two a prepared gear ratio mounted on another two clutch shafts respectively, wherein the other prepared gear is one prepared gear lower than the workinggear. The triple-clutch parallel-shaft-output automatic transmission has the advantages that shift delay as in dual-clutch transmissions is avoided; in case of road jamming, high heat and abrasion ofthe clutches can be relieved; the transmission herein employing the parallel shaft output structural form has short length and can meet the requirement of front-engine automobiles for transmission length.

Description

Technical field [0001] The invention relates to a three-clutch parallel shaft output 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 t...
