Abstract
The utility model provides a transmission shaft assembly with light weight and high torsion resistance, and solves the problems that the conventional transmission shaft assembly is complex in structure and high in production and processing cost. The transmission shaft assembly comprises a transmission shaft, wherein universal joints are arranged at two ends of the transmission shaft; each universal joint comprises a retainer and an internal star wheel, a steel ball is arranged on the retainer, and the transmission shaft adopts a hollow tube structure. According to the transmission shaft assembly, the transmission shaft adopting the hollow tube structure is adopted, production and processing materials are saved, the production cost is reduced, the problems of many processing procedures and assembly troubles caused by connection through a spline are solved, the production cost is further reduced, the procedures and assembly links are reduced, various errors are reduced relatively, the precision of the whole transmission shaft assembly is higher, and the using effect is better. The transmission shaft assembly further has the advantages of simple structure, light weight and material saving, and meanwhile, the transmitting torque is improved by 10-15 permillage than that of a common transmission shaft.
Description
Technical field
The utility model relates to a kind of auto parts and components, is specifically related to the high antitorque driving-shaft assembly of a kind of lightweight.
Background technique
Transmission shaft is the vitals of transferring power in automotive transmission, its effect be together with gearbox, ransaxle by the transmission of power of motor to wheel, make automobile produce driving force.Truck drive shaft can be in two between centers in different axle center, the two between centers transferring power that relative position constantly changes even in the course of the work, connect or assemble every accessory and circular object accessory removable or that rotate, general all using light and the good alloy steel pipe of resistance to torsion is made.The effect of truck drive shaft is exactly two between centers, the two between centers transferring power that relative position constantly changes even in the course of the work that make in different axle center.Existing truck drive shaft generally includes two solid semiaxis, two ends and the universal joint of semiaxis fix, the middle spline pair that adopts slip yoke and spline shaft structure, and slip yoke and splined shaft need to complete through forging the complicated technologies such as processing, heat treatment, machining, cost is high, and existing solid semiaxis adopts 40Cr steel to make, reverse transmission effect poor.
Summary of the invention
For solving existing driving-shaft assembly complex structure in background technique, the problem that production and processing cost is high, the utility model provides a kind of lightweight high antitorque driving-shaft assembly.
The technical solution of the utility model is: the high antitorque driving-shaft assembly of a kind of lightweight, comprise transmission shaft, described transmission shaft two ends are equipped with universal joint, and described universal joint comprises retainer and star-wheel, described retainer is provided with steel ball, and described transmission shaft is hollow tubular structure.
As a kind of improvement of the present utility model, described transmission shaft and the universal joint at two ends all fix by laser bonding.
As further improvement of the utility model, between described transmission shaft and the universal joint at two ends, form sealing surface, described sealing surface makes the middle chamber of hollow drive shaft form Seal cage.
As further improvement of the utility model, described transmission shaft adopts the integral type of No. 45 steel to make.
As further improvement of the utility model, the steel ball on the universal joint of described two ends offsets with straight raceway overcoat and out star wheel respectively.
The beneficial effects of the utility model are, adopt the transmission shaft of hollow tubular structure, save the material of production and processing, reduce cost of production, and avoided by spline joint problem,, the problem includes: manufacturing procedure is many and the problem of assembling trouble, further having reduced cost of production, and operation and mounting ring are reduced few, relatively various long-pending worry errors reduce, and whole piece driving-shaft assembly precision is higher, and using effect is better.That the utility model also has is simple in structure, lightweight, save material, and transmitting torque improves the advantage of 10-15 ‰ than common transmission shaft simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment's structural representation.
In figure, 1, transmission shaft; 11, Seal cage; 2, universal joint; 21, retainer; 22, star-wheel; 23, steel ball; 24, straight raceway overcoat; 25, out star wheel; 3, sealing surface.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, the high antitorque driving-shaft assembly of a kind of lightweight, comprise transmission shaft 1, described transmission shaft 1 two ends are equipped with universal joint 2, described universal joint 2 comprises retainer 21 and star-wheel 22, described retainer 21 is provided with steel ball 23, and specifically, the steel ball 23 on described two ends universal joint 2 offsets with straight raceway overcoat 24 and out star wheel 25 respectively.Such structure makes can better transmitting torque.Described transmission shaft 1 is hollow tubular structure, and in particular, described transmission shaft 1 adopts the hollow tube integral type of No. 45 steel to make.The utility model adopts the transmission shaft of hollow tubular structure, save the material of production and processing, reduce cost of production, and avoid by spline joint problem, the problem includes: manufacturing procedure is many and the problem of assembling trouble, further reduced cost of production, and operation and mounting ring reduce less, relatively various long-pending worry errors reduce, whole piece driving-shaft assembly precision is higher, and using effect is better.That the utility model also has is simple in structure, lightweight, save material, and transmitting torque improves the advantage of 10-15 ‰ than common transmission shaft simultaneously.
Described transmission shaft 1 all fixes by laser bonding with the universal joint 2 at two ends.Between described transmission shaft 1 and the universal joint 2 at two ends, form sealing surface 3, described sealing surface 3 makes the middle chamber of hollow drive shaft 1 form Seal cage 11.Adopt that the universal joint at the fixing two ends of mode of laser bonding not only has that processing technology is simple, efficiency is high, outward appearance is beautiful, the fixing advantage such as reliable, and the Seal cage forming and isolate from outer air formation vacuum, can strengthen the intensity of axle.
Every technician's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this model utility; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
