Embodiment 1

[0017] Embodiment 1 A description of the structure of a transmission system of a five-speed mechanical automatic transmission

[0018] Such as figure 1 , figure 2 As shown, a five-speed mechanical automatic transmission transmission system, the transmission includes a left box body 25, a right box body 11, a support body 4, an input shaft 1, an output shaft 26, an intermediate shaft 10, an intermediate shaft 14, an inverted Gear shaft 12, first gear driving gear 8, second gear driving gear 7, third gear driving gear 3, fourth gear driving gear 6, fifth gear driving gear 2, reverse gear driving gear 9, first gear passive gear 17, second gear passive gear 18. Third gear passive gear 22, fourth gear passive gear 20, fifth gear passive gear 24, reverse gear passive gear 15, reverse gear intermediate gear 13, input shaft constant meshing gear 28, middle one shaft constant meshing gear 5, output shaft constant Engagement gear 21, intermediate two-shaft constant mesh gear 27, firs...

Embodiment 2

[0027] Embodiment 2 A five-speed mechanical automatic transmission transmission system power transmission route and working principle

[0028] Neutral. The power is transmitted to the input shaft of the transmission system, and the transmission shift actuator controls each synchronizer not to mesh with any gear driving gear, the power cannot be transmitted to the output shaft of the transmission system, and the transmission is in the neutral position.

[0029] one block. The gear shift actuator of the transmission controls a reverse gear synchronizer 16 to mesh with a first gear driven gear 17, and all the other synchronizers do not mesh with any gear gears. At this time, the power from the input shaft 1 sequentially passes through the input shaft constant meshing gear 28, the middle shaft constant meshing gear 5, the middle shaft 10, the first gear driving gear 8, the first gear driven gear 17, the first reverse gear synchronizer 16, the middle gear The two shafts 14, t...

Abstract

The invention relates to a transmission system of a five gears mechanical automatic transmission. The transmission system of the five gears mechanical automatic transmission comprises box bodies, an input shaft, an intermediate first shaft, an intermediate second shaft, an output shaft, a reverse gear shaft, gears on each shaft and a plurality of synchronizer. The box bodies are composed of a leftbox body and a right box body, a supporting body is arranged between the two box bodies, and the place between the left and right box bodies and the supporting body are formed by the connecting and assembling of a screw or a bolt. The input shaft and intermediate first shaft realizes power transmission by a pair of constant mesh gear pairs, a five-gear driving gear and a three-gear driving gear are arranged on the input shaft, and a four-gear driving gear, a second-gear driving gear, a one-gear driving gear and a reverse-gear driving gear are fixedly arranged on the intermediate first shaft.The output shaft and intermediate second shaft realizes power transmission by a pair of constant mesh gear pairs, a five-gear driven gear, three-five gears synchronizer, three gears driven gear are arranged on the three-gear driven gear, intermediate second shaft constant mesh gear, a four-gear driven gear, two-four synchronizer, two-gear driven gear, one-gear driven gear, reverse-gear synchronizer and reverse gear driven gear are arranged on the intermediate second shaft. A reverse-gear intermediate gear is arranged on the reverse-gear shaft. The transmission system of the five-gear mechanical automatic transmission is beneficial to shortening the shifting time of the mechanical automatic transmission and improving the shifting quality.

Description

technical field [0001] The invention relates to the field of vehicle automatic transmission systems, in particular to a mechanical automatic transmission transmission system. Background technique [0002] The automatic shifting of the car makes the vehicle easy to drive, reduces the driver's labor intensity, thereby improving driving safety, and reducing the impact of the driver's technical level on the car's power, economy, emission indicators and smoothness, ensuring the safety of the vehicle's power transmission system. In good working order. Therefore, automobile automatic transmissions are widely used. [0003] Mechanical automatic transmission (AMT) is based on the existing manual gear mechanical transmission, and is composed of an automatic control system. It has high transmission efficiency, good fuel economy, reliable work, low manufacturing cost, and good production inheritance. Advantages, easy to be accepted by manufacturers. However, AMT has problems such as ...
