Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0044]This embodiment provides a 10-speed mechanical automatic transmission, which adopts a 5X2 "barrel" structure as a whole, full helical gears, and both the main and auxiliary boxes adopt a double countershaft structure. Including the clutch housing, the transmission housing, the rear cover housing, the first shaft, the second shaft, and the main shaft of the auxiliary box are arranged in sequence from the input end to the output end; the shaft end of the first shaft is integrated with the fifth-speed gear, and the shifting gear is reserved for combining the ring gear. There are reverse gear, first gear, second gear, third gear, and fourth gear on the second shaft, and the axial movement is limited by setting corresponding grooves and spline pads on the second shaft, and a reverse gear sliding sleeve 1, 2nd and 3rd gear sliding sleeves, 4th...

Abstract

The invention provides a ten-gear mechanical automatic transmission, and solves the problems that noise is large, efficiency is low and driving fatigue is caused by too many gears in the prior art. The 10-gear mechanical automatic transmission is of a 5*2 two-section type main box and auxiliary box structure, a main box is provided with five gears, and an auxiliary box is provided with a high gearand a low gear; a first shaft, a second shaft and an auxiliary box spindle are sequentially arranged from the input end to the output end; when the first shaft rotates, a left middle shaft and a right middle shaft are driven to rotate through a five-gear gear which is normally engaged; a reverse intermediate gear is arranged on a reverse intermediate shaft and is respectively and simultaneously engaged with the intermediate shaft reverse gear and the reverse gear; the tail end of the second shaft is fixedly connected with an auxiliary box driving gear which is in transmission along with the second shaft; an auxiliary box transmission gear and an auxiliary box intermediate shaft speed reduction gear are fixedly arranged on the auxiliary box intermediate shaft in sequence; when an auxiliarybox synchronizer slides forwards to be combined with the auxiliary box driving gear, the high gear is obtained; when the auxiliary box synchronizer slides backwards to be combined with the auxiliarybox spindle reduction gear, the low gear is obtained.

Description

technical field [0001] The invention relates to a mechanical automatic transmission. Background technique [0002] As the main part of the vehicle power transmission system, the transmission plays a matching role between the engine and the driving wheels. By changing the transmission ratio, the car can get the required driving force and speed under different conditions of use. The engine works within the most favorable working conditions, which directly affects the power and fuel economy of the vehicle. [0003] At present, the heavy-duty truck transmissions on the market are mainly traditional mechanical transmissions, which are noisy and low-efficiency; when the transmission shifts gears, it is necessary to ensure that the gear meshes are not impacted, and a synchronization device is required. Usually, a synchronizer is used for synchronous shifting. When the shifting force is large Or when changing gears frequently, the synchronous material is easy to wear, which affects...
