Embodiment Construction

[0032] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The present invention provides a 13-speed double intermediate shaft wide speed ratio high torque full synchronizer transmission, the transmission adopts a 2×7-1 structure type and main and auxiliary box structures, the transmission of this structure is compared to the front auxiliary box, The transmission with the structure of the main box and the rear auxiliary box has a simple structure and has low requirements on the driving level of the driver. At the same time, the maximum input torque of the transmission can reach 2600Nm, and the speed ratio range is 19.9, which is different from the existing 20-speed transmission. The speed ratio range is similar, so the transmission can not only improve the acceleration and power of the vehicle, but also help adapt to various road conditions, and the driving operation is c...

Abstract

The invention provides a 13-gear wide-speed-ratio large-torque full synchronizer transmission with double intermediate shafts to solve the problems that an existing 12-gear transmission is narrow in speed ratio, and a 20-gear transmission is complex in structure and has high reliance on a vehicle clutch disengaging mechanism. The transmission comprises a seven-gear main case transmission and a two-gear auxiliary case transmission. The seven-gear main case transmission has seven forward gears and one reverse gear, wherein a climbing gear and the reverse gear adopt sliding sleeve type gear engaging, and other gears all adopt synchronizer gear engaging. The transmission adopting the main-auxiliary case structure form is simple in structure and easy and convenient to operate, can achieve a large speed ratio range and considers both power performance and economy, and vehicle emission can reach the standard more easily.

Description

technical field [0001] The invention relates to an automobile transmission, in particular to a 13-speed double countershaft wide-speed-ratio high-torque full-synchronizer transmission. Background technique [0002] With the rapid development of the economy, multi-gear transmissions are widely used on heavy duty dump trucks. At the same time, with the continuous improvement of automobile fuel consumption and emission requirements, the powertrain matching of the vehicle must meet the vehicle emission standards and the user's requirements for vehicle power and comfort. Among them, the engine operating speed range, load conditions and driving gears have an important impact on vehicle emissions. [0003] In order to make the whole vehicle meet the fuel consumption and emission requirements, it is necessary for the powertrain of the whole vehicle to ensure fuel economy, and one of the most important measures is to increase the number of transmission gears and widen the transmissi...
