Description
Technical field
The utility model belongs to transmission shaft technical field, particularly relates to a kind of aluminium driving shaft.
Background technology
The common drive axle of originally more than 1.2 meters, in order to meet critical speed, make two sectional type, and in part except central support adopts elastomeric material, all the other all adopt steel part to be made, its structure is: the two sectional type transmission shaft (as shown in Figure 1) of 15 parts compositions such as shaft clevis 9-pad 10-nut 11-universal-joint 3-weld yoke 4-rear axle tube 12-weld yoke 4-universal-joint 3-flanged yoke 2 grade in the middle of cliding yoke 1-universal-joint 3-weld yoke 4-front axle tube 6-middle spline shaft 7-central support 8-, wherein except central support, all the other are all steel matter.Central support is elastomeric material, and the special rubber producer needing environmental demands higher makes.This propeller shaft slip fork is connected with change speed gear box, and central support is mounted on cross member of frame, and flanged yoke is connected with back axle.Owing to having a central support in the middle of existing transmission shaft, corresponding automobile must increase a crossbeam to install this central support, car load be installed inconvenient, and increase complete vehicle weight.Because central support is elastomeric material, after the time length of use, the easy aging deliquescing of rubber, the transmission shaft amplitude of oscillation strengthens, and vehicle easily produces vibration noise.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and providing a kind of structure simple, weight alleviates 40-60% on year-on-year basis, installs simple and convenient, eliminate central support structure, avoid the aluminium driving shaft of the Vehicular vibration noise caused due to central support.
The purpose of this utility model has been come by following technical solution, this aluminium driving shaft, comprise cliding yoke, flanged yoke, two universal-joints symmetrically and weld yoke, described weld yoke adopts aluminium bar forging forming, two weld yokes are connected with two universal-joints respectively, and one of them universal-joint is connected with cliding yoke, and this cliding yoke is connected with change speed gear box, another universal-joint is connected with flanged yoke, and this flanged yoke is connected with back axle; Described transmission shaft also comprises central siphon, and this central siphon adopts the tubing of cold drawn forming, and described central siphon between two weld yokes be symmetric, and is molded as one by friction welding.
As preferably, described weld yoke and central siphon all adopt 6061-T6 aluminum alloy materials.
The beneficial effects of the utility model are: adopt the aluminium driving shaft of one-part form to substitute two sectional type plain steel transmission shaft, structure is simple, lightweight, alleviate 40-60% on year-on-year basis, easy for installation, eliminate central support structure simultaneously, avoid the Vehicular vibration noise because central support ageing of rubber causes; Two joints change a joint into, can reduce true joint angle further, decrease the universal-joint consumption of 1/3, greatly can improve the service life of consumable accessory universal-joint, and one-piece parts quantity reduces can reduce fault rate, improves product reliability.
Accompanying drawing explanation

Fig. 2 is aluminium driving shaft structural representation of the present utility model.
Label in accompanying drawing is respectively: 1, cliding yoke; 2, flanged yoke; 3, universal-joint; 4, weld yoke; 5, central siphon; 6, front axle tube; 7, middle spline shaft; 8, central support; 9, middle shaft clevis; 10, pad; 11, nut; 12, rear axle tube.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in Figure 2, the utility model comprises cliding yoke 1, flanged yoke 2, two universal-joint 3 symmetrically and weld yoke 4, described weld yoke 4 adopts aluminium bar forging forming, solution treatment at 529 DEG C of temperature, ageing treatment is carried out afterwards, finally by cutting earhole, jump ring and cylindrical at 177 DEG C of temperature.Two weld yokes 4 are connected with two universal-joints 3 respectively, and one of them universal-joint 3 is connected with cliding yoke 1, and this cliding yoke 1 is connected with change speed gear box, and another universal-joint 3 is connected with flanged yoke 2, and this flanged yoke 2 is connected with back axle; Described transmission shaft also comprises central siphon 5, and this central siphon 5 adopts the tubing of cold drawn forming, and described central siphon 5 between two weld yokes be symmetric 4, and is molded as one by friction welding.
Described weld yoke 4 and central siphon 5 all adopt 6061-T6 aluminum alloy materials, and density is 2.7x10-6kg/mm3, are about 1/3rd of steel density (7.8x10-6kg/mm3), and under equal volume, weight is about 30% of steel part.
The utility model is not limited to above-mentioned embodiment; no matter do any change on its shape or material are formed; every employing structure design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection domain.
