Abstract

The invention discloses a mining dump truck power shift gearbox which mainly solves the problem that an existing gearbox has too many parts and is complex is transmission route. The mining dump truck power shift gearbox mainly comprises an input shaft, an output shaft and six intermediate shafts, wherein each intermediate shaft is provided with a clutch, and the input shaft, the output shaft and the six intermediate shafts are respectively provided with a gear. According to the transmission route of the shafts and from the perspective of an end face, the input shaft (24), the first intermediate shaft (25), the sixth intermediate shaft (22) and the third intermediate shaft (19) are arranged in a quadrilateral mode; the input shaft (24), the second intermediate shaft (18), the fifth intermediate shaft (21) and the third intermediate shaft (19) are also arranged in a quadrilateral mode; the output shaft (23), the fifth intermediate shaft (21), the third intermediate shaft (19) and the fourth intermediate shaft (20) are arranged in a quadrilateral mode. The mining dump truck power shift gearbox adopting the structure for transmission has the advantages that the transmission route is short, the transmission efficiency is high, and few parts are used; therefore, the mining dump truck power shift gearbox is suitable for popularization and usage.

Description

technical field [0001] The invention relates to a power shift gearbox, in particular to a power shift gearbox suitable for mining dump trucks. Background technique [0002] At present, the gearboxes of construction machinery such as mining dump trucks, wheel loaders, graders, and two-end busy equipment usually have two types: planetary and fixed-axis. The planetary gearbox has complex processing and high precision requirements. , few gears, low transmission efficiency, and high manufacturing cost. Another type of fixed-axis gearbox requires two clutches, ten gears and six engagements to achieve power output. The first gear forward generally has a higher utilization rate. The more the number of gears and the number of meshes in the transmission process, the It directly leads to the decrease of transmission efficiency and the increase of wear and tear of parts, and the increase of maintenance cost. Simultaneously, the transmission line of this gearbox is long, and transmissi...
