Problems solved by technology

At present, before there are other suitable automatic transmissions for new energy vehicles, they have to choose a traditional manual shift transmission plus an electronically controlled automatic gear mechanism, that is, an AMT transmission. AMT will cause power interruption and difficulty in shifting gears. The gear synchronizer is easy to damage, and the shift drive structure is complex and easy to damage. These inherent shortcomings make this gearbox unable to meet the requirements of new energy vehicles. This is also a helpless move for the new energy vehicle industry.

Abstract

The invention provides a gearbox special for a new energy automobile, and belongs to the technical field of automobile gearboxes.The gearbox comprises a gearbox shell, an input shaft arranged at the front end of the central axis of the gearbox shell and an output shaft arranged at the rear end of the central axis of the gearbox shell.The input shaft is connected with a gearshift through a gear pair, the input shaft directly transmits power to the output shaft, the gearshift is connected with a hydraulic electronic valve block, and a hydraulic pump pumps pressure oil into the hydraulic electronic valve block.By means of the gearbox, efficient transmission of the powder of an engine is guaranteed, efficient recovery of the braking energy of the new energy automobile is guaranteed, the idling start-stop function of the engine of the new energy automobile is retained, the driving torque of a motor is reduced, the large current of a battery is reduced, the loading capacity and climbing capacity of the new energy automobile are improved, the maximum running speed of the new energy automobile is increased, and the acceleration time of the new energy automobile is shortened.

Description

technical field [0001] The invention belongs to the technical field of gearboxes, in particular to a gearbox dedicated to new energy vehicles. Background technique [0002] New energy vehicles have entered the public's field of vision with the image of "no pollution and low noise". At present, before the emergence of other suitable automatic transmissions, new energy vehicles have to use traditional manual shifting transmissions plus electronically controlled automatic shifting mechanisms, namely AMT transmissions. AMT shifting will cause power interruption and difficulty in shifting. The gear synchronizer is easy to be damaged, and the shift drive structure is complex and easy to damage. These inherent shortcomings are that this gearbox cannot meet the use requirements of new energy vehicles, which is also a helpless move for the new energy vehicle industry. Therefore, it is an urgent requirement of the new energy vehicle industry to hope to have a new type of gearbox that...
