Abstract
The invention discloses a rear axle shaft of a heavy truck. The rear axle shaft of the heavy truck is characterized by comprising a curved surface (1), a flange plate (2), a concave portion (3), a bearing neck (4), a shaft body (5), a cone (6), a spline (7), a bolt hole (8), a threaded hole (9), a spline groove (10) and spline teeth (11), wherein one end of the shaft body (5) is provided with the flange plate (2) which is connected with an axle body; the bolt hole (8) and the threaded hole (9) are formed in the flange plate; the bearing neck (4) is arranged at a position nearby the flange plate (2); the other end of the shaft body (5) is provided with the spline (7); and quenching and magnetic flaw detection are required to be performed on the surface of the rear axle shaft.
Description
Technical field
The present invention relates to car rear axle semi-axis, be specifically related to a kind of heavy motor vehicle rear axle shaft.
Background technology
The rotation of two semiaxis of automobile is different, and a side is hurried up, and a side is a little slower, and Here it is requires to need to be furnished with diff on transmission shaft.Diff is exactly to allow the wheel on both sides turn over the different device of speed, and semiaxis is just connected on diff and receives on wheel.
Automobile axle shaft has two kinds of full-floating and semi-floatings.All there is defect in these two kinds of patterns: a fully floating axle transmitting torque, do not bear any counter-force and moment of flexure, and fully floating axle is easy to dismounting, only need back out the bolt of rear end plate of semiaxis and can extract semiaxis out, and wheel and axle housing is supported automobile in the same old way during maintenance.Semifloating axle shaft is transmitting torque both, bears again whole counter-forces and moment of flexure, and its supporting structure is simple, cost is low, but this semiaxis dismounting trouble, and if half axle fracture in running car, the danger that easily causes wheel to fly off.
Summary of the invention
The object of the invention is to: a kind of heavy motor vehicle rear axle shaft is provided, adopts alloy steel solid forging, after prtreatment, the function of surface of semiaxis is taked to different Technologies for Heating Processing, improved bulk strength and resistance to abrasion, strengthened safe reliability.
The technical scheme that technical solution problem of the present invention adopts is: a kind of heavy motor vehicle rear axle shaft, this heavy motor vehicle rear axle shaft comprises curved surface, flange, groove, bearing neck, axis body, cone, spline, bolt hole, tapped bore, spline and spline tooth, axis body one end is provided with the flange being connected with pontic, on flange, be provided with the tapped bore of bolt hole and dismounting, close on flange place and be provided with bearing neck, the other end of axis body is provided with spline, and the surface of semiaxis need be through quenching and magnetic inspection.
A kind of heavy motor vehicle rear axle shaft of the present invention, the flange of axis body one end is provided with curved surface and groove.
A kind of heavy motor vehicle rear axle shaft of the present invention, is provided with cone between spline and axis body.
A kind of heavy motor vehicle rear axle shaft of the present invention, spline circumference is provided with well-distributed spline tooth and spline.
The invention has the beneficial effects as follows: simple in structure, cost is low, be easy to manufacture, and has improved bulk strength and resistance to abrasion, has strengthened safe reliability, has extended the service life of semiaxis.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is spline amplification view in Fig. 1.
In Fig. 1 Fig. 2 Fig. 3: 1. curved surface, 2. flange, 3. groove, 4. bearing neck, 5. axis body, 6. cone, 7. spline, 8. bolt hole, 9. tapped bore, 10. spline, 11. spline tooths.
The specific embodiment
As shown in Fig. 1 Fig. 2 Fig. 3, a kind of heavy motor vehicle rear axle shaft, this heavy motor vehicle rear axle shaft comprises curved surface 1, flange 2, groove 3, bearing neck 4, axis body 5, cone 6, spline 7, bolt hole 8, tapped bore 9, spline 10 and spline tooth 11, axis body 5 one end are provided with the flange 2 being connected with pontic, on flange, be provided with the tapped bore 9 of bolt hole 8 and dismounting, close on flange 2 places and be provided with bearing neck 4, the other end of axis body 5 is provided with spline 7, and the surface of semiaxis need be through quenching and magnetic inspection.
A kind of heavy motor vehicle rear axle shaft of the present invention, the flange 2 of axis body 5 one end is provided with curved surface 1 and groove 3.
A kind of heavy motor vehicle rear axle shaft of the present invention, is provided with cone 6 between spline 7 and axis body 5.
A kind of heavy motor vehicle rear axle shaft of the present invention, spline 7 circumference are provided with well-distributed spline tooth 11 and spline 10.
