Problems solved by technology

[0003] The existing technical solution provides the highest number of forward gears, which cannot meet the requirements; the maximum speed ratio of the gearbox can only reach 6
In addition, most gearboxes still adopt the transmission structure of installing two clutch packs on one shaft, which increases the length of the shaft and increases the bending deformation of the shaft, which affects the life of the shaft, the transmission accuracy of the gears, and the noise of the gearbox. Larger, also increases the difficulty and cost of shaft manufacturing

Embodiment 1

[0042] see figure 1 , figure 2 As shown, this embodiment provides a multi-speed fixed-shaft shift gearbox. The gearbox includes S-in shaft 1, SVH shaft 2, SR shaft 3, S1 shaft 4, S2 shaft 5, S3 shaft 6, SVL shaft 7, S4 shaft 8 and S-out shaft 9 and multiple clutches. The plurality of clutches are CR clutch 33 , CVH clutch 23 , C1 clutch 44 , C2 clutch 53 , C3 clutch 63 , CVL clutch 74 , and C4 clutch 83 . The S-in shaft 1 is connected with the engine to receive power for transmission. The S-in shaft 1 is installed with a first fixed gear 11 and a second fixed gear 12, and the S-out shaft 9 is connected with the transmission shaft, which can connect the S- The in axle 1 is used to transmit the received power to the vehicle. A sixth fixed gear 91 and a seventh fixed gear 92 are mounted on the S-out shaft 9 . The SVH shaft 2 is equipped with a third fixed gear 21, a first floating gear 22 and a CVH clutch 23; the CVH clutch 23 is connected with the first floating gear 22 for...

Abstract

The invention discloses a multi-gear fixed shaft type gear shifting gearbox in the technical field of engineering machinery, and aims to solve the problems that a gearbox in the prior art is complex in structure, unsmooth in gear shifting and gear shifting and the like. The four-gear transmission comprises an SVH / SR / S1 / S2 / S3 / SVL / S4 shaft, CVH / CR / C1 / C2 / C3 / CVL / C4 clutches are correspondingly arranged on the shafts respectively, and eight forward gears and four reverse gears are achieved under the action of power through cooperation of an S-in / SVH / SR / S1 / S2 / S3 / SVL / S4 / S-out shaft, the CVH / CR / C1 / C2 / C3 / CVL / C4 clutches and mutual meshing and / or coaxial relation of floating gears and fixed gears connected to the shafts; the gearbox is suitable for engineering machinery vehicles, gear shifting impact can be reduced, gear shifting smoothness can be improved, the overall structure in the gearbox is compact, machining difficulty is small, parts are few, manufacturing cost is low, and assembling and maintaining are more convenient.

Description

technical field [0001] The invention relates to a multi-speed fixed-axis shift gearbox, which belongs to the technical field of construction machinery. Background technique [0002] Gearboxes in the field of construction machinery are divided into planetary gearboxes and fixed-shaft gearboxes according to the gear train. The latter has a small number, short service life and high failure rate, while the latter fixed-axis gearbox has a simple structure design and is easy to realize the number of gear shifts, the speed ratio, and the adaptability. It is convenient to manufacture and maintain, and can meet the requirements of construction machinery gearbox The requirement of flexibility and modularity is the development trend of the high-end market of construction machinery in the future. Taking motor graders as an example, the gearboxes currently used in motor graders are mainly fixed-axis gearboxes with six fronts and three rears based on ZF technical solutions, and the speed...
