Abstract
The utility model provides a full-floating drive axle used on an electric sightseeing bus and an electric van. The full-floating drive axle comprises a redactor, an axle housing and a semi-axle, wherein the redactor is connected with the axle housing through a bolt; a shaft I and a shaft II are sequentially arranged on two sides inside a redactor box body of the redactor; the outer end of the shaft II is meshed with a big wheel which drives a differential housing on one side to rotate; the outer side of the shaft I is further connected with a bond on the shaft II through a connecting shaft gear II; and the axle housing is formed by welding an axle housing middle piece, an axle housing cover, a sleeve and a flange shaft. The full-floating drive axle has the benefits that a full-floating structure is adapted, the semi-axle can not bear the bending moment but only the twisting moment, so as to improve the load-bearing capacity; the full-floating drive axle is suitable for electric vehicles of which the loads of rear axles are smaller than 1.2 t; and a secondary expansion type helical cylindrical gear retarding mechanism is adopted inside the redactor, and various velocity ratios are designed by adjusting the number of gear teeth, the modul number, the helical angle and the coefficient of displacement, so as to meet the requirements of various vehicles for the velocity ratios.
Description
Technical field
The utility model relates to a kind of electric motor car driving bridge mechanism, relates in particular to a kind of full-floating drive axle that is used for electronic tour bus and electronic load-carrying vehicle.
Background technology
The electric axle of Sheng Chan,Xiao Shouing mainly adopts the semi-floating back axle in the market, semiaxis not only bears moment of torsion but also bear moment of flexure, limited its load-carrying capacity greatly,, just might cause some more serious safety misadventures if be used for the occasion of the bigger carrying of some needs reluctantly.
The utility model content
At above defective, the purpose of this utility model provides that a kind of noise is little, external form is compact, highly versatile, the higher full-floating drive axle that is used for electronic tour bus and electronic load-carrying vehicle of safety factor, thereby makes and can assemble different gears and the final purpose that realizes different speed ratios with a kind of casing.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of full-floating drive axle that is used for electronic tour bus and electronic load-carrying vehicle, comprise retarder, axle housing and semiaxis, described retarder is connected with axle housing by bolt, the inner both sides of the reduction case of this retarder set gradually an I, axle II, and the differential casing that axle II outer end and bull wheel engagement and this bull wheel drive a side rotates; The described axle I outside is connected with key on the axle II by adapter shaft gear II again, and described axle housing is welded to form by axle housing stage casing, axle housing lid, sleeve pipe and flanged shaft.
The beneficial effect that is used for the full-floating drive axle of electronic tour bus and electronic load-carrying vehicle described in the utility model is: adopt the full-floating structure, semiaxis only bears moment of torsion and does not bear moment of flexure, improved its load-carrying capacity, applicable to the battery-driven car of back axle load below 1.2t, retarder inside is secondary expansion equation helical spur gear speed reduction gearing, by adjusting the method for the gear number of teeth, modulus, helical angle and modification coefficient, design various speed ratios, thereby satisfy the speed ratio requirement of various vehicles; Make retarder and axle housing adopt bolted to be connected, semiaxis one end is used for driving the wheel hub rotation by being bolted on the wheel hub, wheel hub connects fastening and the phenomenon that semiaxis is deviate from can not take place, have have no abnormal sound, noise is little, external form is compact, highly versatile, characteristics that safety factor is high.
