Embodiment 1

[0039] A clutch normally closed dual gear gearbox includes: input shaft 1, gear I 2, synchronizer I 3, gear II 4, dual gear A (left teeth 5, right teeth 6), synchronizer II 7, gear III 8, output shaft 9 , duplex gear B (10 right teeth, 11 left teeth), synchronizer III 12, duplex gear C (13 right teeth, 14 left teeth), gear Ⅳ 15, clutch friction plate 16 and clutch pressure plate 17, transmission power from Input shaft 1 enters, and output shaft 9 outputs.

[0040] According to the order of clutch friction plate 16, gear I2, gear II4, double gear A (left tooth 5, right tooth 6) and gear III8, they are placed on the input shaft 1 sequentially along the direction of power transmission, and the clutch pressure plate 17 is connected to input axis 1. Duplex gear B (right tooth 10, left tooth 11), duplex gear C (right tooth 13, left tooth 14) is empty sleeve on the output shaft 9, and gear IV 15 is connected on the output shaft 9. Gear III 8 meshes with right tooth 10 of dual gear ...

Abstract

The invention provides a normally-closed duplex gear transmission for a clutch and a shifting process control method of the normally-closed duplex gear transmission. The two-shaft type design is adopted. The transmission comprises an input shaft, a first gear, a first synchronizer, a second gear, a duplex gear A, a second synchronizer, a third gear, an output shaft, a duplex gear B, a third synchronizer, a duplex gear C, a fourth gear, a clutch friction plate and a clutch pressure plate. According to the normally-closed duplex gear transmission, four effective gears and three boosting gears can be provided; in the working gear, the clutch is in the normally-closed state, the clutch is meshed only when the gear is shifted, the system control difficulty of the clutch is lowered, and the service life of the clutch is prolonged; it is guaranteed that power is not interrupted in the shifting process, the adjacent speed ratio gears are adopted for boosting, the sliding wear loss of the clutch can be reduced, and the energy loss is reduced; and vehicle starting and power-failure-free gear shifting can be achieved only through one clutch, the number of parts is small, and cost is low.

Description

technical field [0001] The invention belongs to the field of automobile transmission, and in particular relates to a clutch normally closed dual gear transmission and a shift process control method thereof. Background technique [0002] Automatic mechanical transmission (AMT) is based on manual transmission, and realizes automatic gear shifting by adding gear selection and clutch actuators and corresponding sensors and control units. The mechanical automatic transmission effectively solves the problems that the manual transmission cannot automatically shift gears and the transmission efficiency of the automatic transmission is low. It has a simple structure, low cost and high transmission efficiency. However, the inherent defect of power interruption during the shifting process has not been fundamentally resolved, and it has brought about the shifting shock during the shifting process and the problem of uneven starting, which affects the power of the vehicle and the comfort ...
