Abstract

The invention discloses an overload vehicle gearbox, and belongs to the field of gearboxes. The overload vehicle gearbox comprises an input shaft, an odd-gear transmission shaft, an even-gear transmission shaft and an output shaft. An input gear is arranged on the input shaft, a transmission gear A and an odd-gear gear set are arranged on the odd-gear transmission shaft, the input gear is engagedwith the transmission gear A and a transmission gear B, and the transmission gear B and an even-gear gear set are arranged on the even-gear transmission shaft. A driven gear set corresponding to the odd-gear gear set and the even-gear gear set is arranged on the output shaft, and the odd-gear transmission shaft and the even-gear transmission shaft are provided with a first one-way clutch and a second one-way clutch correspondingly. The clutches are not disconnected firstly during gear shifting, running is switched to the high gear under the condition that running continues at the low gear to maintain the advancing speed, and the low gear is disconnected after running at the high gear is normal, and therefore speed losses caused by an original manner are avoided, and switching from the lowgear to the high gear is smoothly achieved.

Description

technical field [0001] The invention belongs to the technical field of gearboxes, and in particular relates to a heavy-duty vehicle gearbox. Background technique [0002] Agricultural machinery such as tractors, heavy-duty vehicles such as trucks, construction machinery, etc., are mainly characterized by heavy loads and not easy to shift gears. An example is a tractor, which usually works in the fields. Its gear shifting is generally from low gear to high gear. First, use the first gear to start, and then accelerate the accelerator to make the engine reach a higher speed. When the engine speed is high, the output power margin is relatively large, so it is necessary to shift to a high gear. The existing manual gearbox will step on the clutch, the engine and the output end will be disconnected, the shift lever will separate the gear set of low gear, and then close the gear set of high gear, and then release the clutch pedal, so that the engine and The outputs are reconnecte...
