Description

The utility model relates to mechanical engineering, in particular to the wheels of utility vehicles.

Known 13 "wheel for front-wheel drive vehicles manufactured by VAZ, made of stampable sheet material, consisting of a rim and a disk having bearing surfaces, central and mounting holes, ventilation windows and an annular stiffener [1].

The disadvantage of the wheel of this design is the use of expensive wedge dies used for punching vents, which, as a result, makes the manufacturing technology more time-consuming and expensive.

The technical result of the proposed solution is to create an optimal design without these drawbacks while maintaining high wheel bearing capacity.

This result is achieved due to the fact that in the vehicle’s wheel made of stampable sheet material, consisting of a rim and a disk having supporting surfaces located in one horizontal plane, central and mounting holes, ventilation windows and an annular stiffener, the rectilinear part of the section the vertical plane passing through the central axis of the wheel, the surface of the concave trapezoidal punching discs, on which the ventilation windows are located, is made at an angle α = 15-18 ° to the horizontal plane, the rectilinear part of the section by a vertical plane passing through the central axis of the wheel, the surface of the disk located between the trapezoidal stampings is made at an angle α = 15-20 ° to the horizontal plane, the ring stiffener has a rounding radius R = 5-9 mm , a

ventilation windows have 2 trapezoidal shapes with rounded corners and are oriented with a smaller base towards the center.

The inventive design is illustrated by drawings, in which:

figure 1 is a section of the wheel aa in figure 2;

figure 2 is a top view of the wheel

figure 3 - enlarged views of the elements of the wheel disc

The vehicle wheel contains a rim 1, a disk 2, mounting holes 3, ventilation windows 4 evenly spaced on a concave trapezoidal punching 5, the rectilinear part of the cross section is a vertical plane passing through the central axis 15 of the wheel, the surface of the concave trapezoidal punching 5 of the disk 2 is made at an angle α = 15-18 ° to the horizontal plane, the rectilinear part of the section by a vertical plane passing through the central axis 15 of the wheel, surface 6 of the disk 2 located between the concave trapezoidal by stampings 5, made at an angle β = 15-20 ° to the horizontal plane; the surface of the trapezoidal punchings 5 and the rectilinear part of the surface 6 are mated with the conical part of the surface of the profile 11 with an annular stiffener 7 of radius R = 5-9 mm, the central part 8 of the disk 2 contains the supporting surfaces 9 of the disk, located in the same horizontal plane and divided by equal sections of the elements 10, which are formed from the natural intersection of the conical part of the surface of the profile 11 with the surface adjacent to each mounting hole, and with radial punching 12 of the Central part 8 , the Central hole 13, is concentric with the circle 14, on which the centers of the conical mounting holes 3 are located, while the Central axis 15 and the axis 16 of the mounting holes 3 are parallel.

The working condition of the wheel is ensured by installing and securing it to the hub unit using bolts, taper surfaces

which mate with the tapered surfaces of the mounting holes.

The proposed design of the wheel of the vehicle is a high-tech product with high bearing capacity, with a lower cost of manufacture compared to the prototype.

The claimed technical solution is planned to be implemented at OAO GAZ and delivered for vehicle assembly and to spare parts.
