Abstract
The utility model discloses a kind of Split type duplex driving-shaft assembly, comprise front half part transmission shaft and latter half part transmission shaft; The connecting end of described front half part transmission shaft is provided with middle spline shaft, and the connecting end of latter half part transmission shaft is provided with slip yoke, and the external splines of middle spline shaft matches with the internal spline of slip yoke.The utility model passes through spline fitted by front half part transmission shaft and latter half part transmission shaft, is that two-part transmission shaft can freely be dismantled, assembling respectively, has reduced operator's labor intensity.
Description
Technical field
The utility model relates to auto parts machinery production technical field, is specifically related to a kind of Split type duplex driving-shaft assembly.
Background technique
Along with scientific and technical progress, the target that in recent years, reduce labor intensity, enhance productivity, energy-saving and cost-reducing these themes becomes each enterprise gradually and even government department is pursued, no exception as Automobile Parts Industry.
Duplex transmission shaft, as an important accessory in car transmissions, normally by middle clevis 1, front half part transmission shaft 2 and latter half part transmission shaft 3 are linked together (as shown in Figure 1), the deficiency of this structure is: when producing assembling, part need assemble last from first always, whole heavier, be inconvenient to assemble, labor intensity is larger.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to assembly, technique is simple, the lightweight Split type duplex driving-shaft assembly of assembly.
A Split type duplex driving-shaft assembly, comprises front half part transmission shaft and latter half part transmission shaft; The connecting end of described front half part transmission shaft is provided with middle spline shaft, and the connecting end of latter half part transmission shaft is provided with slip yoke, and the external splines of middle spline shaft matches with the internal spline of slip yoke.
Wherein, the front half part transmission shaft of the opposite side of described middle spline shaft, comprise successively front axle tube, front weld yoke, front universal joint and forward flange fork, forward flange fork links together by front universal joint and front weld yoke, front weld yoke seam end and front axle tube one end are welded and fixed, and the front axle tube the other end and middle spline shaft seam are welded and fixed.
Wherein, offer dust-proof cover shelves and step gear on described middle spline shaft, dust-proof cover is welded on dust-proof cover shelves place, the internal bearings inner ring of intermediate support and step gear interference fit.
Wherein, the latter half part transmission shaft of the opposite side of described slip yoke, comprise rear axle tube, the two ends of rear axle tube are arranged with rear weld yoke, the opposite side of rear weld yoke connects rear universal joint, and slip yoke is connected on the axial rear universal joint of front half part transmission, is connected with rear flange fork on another rear universal joint, rear weld yoke seam end and rear axle tube are welded and fixed, and rear axle tube and rear weld yoke are welded and fixed.
The utility model passes through spline fitted by front half part transmission shaft and latter half part transmission shaft, is that two-part transmission shaft can freely be dismantled, assembling respectively, has reduced operator's labor intensity.
In addition, also there is following technical advantage:
1, reduce clevis, nut, pad, 4 parts of rear axle, reduced the weight of driving-shaft assembly;
2, in assembly process, reduce by 4 procedures, enhance productivity.
3, driving-shaft assembly overall weight is alleviated, reduced complete vehicle weight, reduced complete-vehicle oil consumption, promote whole transmission performance.
