Abstract

The present invention provides a power shift gearbox fit for engineering plant, mainly resolving complex problem of many gearbox spares and transmission route for present engineering plant. The invention is composed of an input shaft, an output shaft, some center shafts and some clutches and gears, wherein some gears form a reversing gear set, the other gears form a driver gear set, the input shaft and the second, sixth center shafts seen from end show triangle arrangement according to the transmission route of axes, the input shaft and the first, second, sixth middle shafts show quadrilateralarrangement, the output shaft and the third, fouth, fifth center shafts show quadrilateral arrangement. The transmission route of the structure is more compact, using less spares, high transmission efficiency.

Description

technical field [0001] The invention relates to a power shift gearbox suitable for engineering machinery, in particular to a power shift gearbox for loaders and graders. Background technique [0002] At present, the gearboxes on construction machinery, such as wheel loaders, graders, dump trucks, and excavators, usually have two types: planetary and fixed-axis. The planetary gearbox has complex processing, high precision requirements, and few gears. , the transmission efficiency is low, and the manufacturing cost is high. Another kind of fixed-shaft gearbox, such as the Chinese invention patent application publication specification CN1068939C, discloses a multi-speed reversing gearbox that can shift gears under load. A gear requires two clutches, ten gears, and six meshes to achieve power output. However, the first gear forward generally has a higher usage rate, about 30%. The more gears and the number of meshes in the transmission process, the more the transmission efficien...
