The scope of the invention

The present invention mainly relates to a device and method of direction and/or concentric (coaxial) install rotary disc on the wheel hub. The present invention mainly relates to the guiding surfaces formed on the outside from the mounting fasteners on the hub, and the drive to radially to align the disk with the wheel hub in order to increase the fatigue life of the wheel.

Prerequisites to the creation of inventions

The present invention is intended to minimize radial runout of the disk brake mounted on the wheel hub, particularly with respect to the wheels of heavy trucks. Radial runout should be taken into account when securing the brake disc to the wheel hub to prevent vibration caused by imbalance of the disk. The brake disc must be concentrically aligned (aligned) with the wheel hub previously fixing the disc on the hub. Fasteners for mounting the disk on the hub is passed through holes formed in the mounting flange of the hub, and impose on the thread (screwed) in the mounting flange on the disk. Vibration may occur due to irregular concentric alignment of the disk with the axis of the hub.

JV is own, which is used for sending and/or alignment to the on-Board side of the vehicle disk brake on the wheel hub requires the use of machined guide diameter of the ring shape (the guide element is of annular shape with a predetermined diameter on the disk, which interacts with machined guide diameter of the ring shape (annular guiding element forms with the same specified diameter) on the wheel hub. Previously known guiding elements are located between the axis of the hub and studs for mounting wheels or, generally speaking, on a smaller initial diameter of the circle than the initial diameters of the circles fasteners for installation disk and studs for mounting the wheel to the hub. This is the location of the sending device forms a discontinuous thickness of the cross section of the housing hub and flange due to continuously or individually (discrete) set of the tides, machined undercut or elements with a small radius is formed on a side region of the flange on the wheel hub. These notches and place increasing stresses in the flange of the hub to reduce the fatigue life of the hub.

Wheel hubs are experiencing cyclical and average voltage, which can be concentrated in the side region is STI flange of the wheel hub. These stresses are particularly concentrated in the gaps in the section thickness of the hub, especially when such places increasing stress is formed on the initial diameter of a circle equal to or smaller than the diameter of the initial circumference of the fixing part on the hub that connects with it the disk or wheel. Places increasing stress formed at the expense of the previously known guide elements have a mixed effect on cyclic and mean stresses wheel hub, increasing the level of stress at these points and reducing the fatigue life of the wheel.

It is desirable to create a device and method direction of the disc on the wheel hub by the arrangement of guide elements outside diameters of the initial circles fasteners or studs. The advantage of this solution is to reduce the effects of fatigue on the wheel hub. Additionally, it is desirable to create a method of direction of the disc on the wheel hub, at which the guide elements do not create places (points) increase stress.

The invention

The first variant of the present invention is directed to the formation of the guide surface with the area of the wheel to the mounting flange, with the initial diameter of a circle greater than the diameter of the initial circumference of the fixing part of the disk, and a cover member which it engages with the sector of the disk brake. The diameter of the initial circumference of the guide surface may also be larger than the initial diameter of the circle studs to install the wheels, which is pressed into the mounting flange of the wheel hub. The guide device may be a solid (continuous) surge limiting guide diameter or alternatively may be a number of individual (discrete) tides formed along the outer edge of the mounting flange, with the plot of the hub radially outside area of the disk, for a concentric direction of the hub and disc Assembly.

In the alternative (second) embodiment, the outer guide surface may be formed on the mounting flange of the disk with the initial diameter of a circle greater than the diameter of the initial circumference of the fixing part of the disk for covering the entrance into engagement with the guide section of the hub outside of the studs for mounting the wheel to the hub. Guiding device on the mounting flange of the disk may be continuous ledge formed circumferentially around the outer perimeter of the mounting flange of the disk, or may be a number of individual tides formed along the outer perimeter of the mounting flange of the disk and intended to enter into engagement with the guide surface on the mounting flange of the hub. Guide surface h is the hub may be in the form of grooves in the mounting flange of the hub, to engage with the sector of the disk and create a smooth profile around the circumference of the assembled host.

The location of the guide surfaces on a diameter larger than the diameter of the holes for the studs for the wheels, help fix places increasing stress between the axle and the holes for the studs for the wheel to increase the fatigue life of the hub. Education guide surfaces outside of fasteners and studs reduces grooves machined undercut and places increasing stress and allows you to create a continuous thickness of section in the hub flange between the housing and mounting holes.

Detailed description of the invention

Figure 1 shows a brake disc mounted on the wheel hub. It should be borne in mind that the wheel hub, hub steering wheels and hub drive are considered to be in accordance with the present invention are almost the same. These nodes contain the hub installed between the axle of the vehicle and the wheel, and a disk mounted on the hub for the application of brake force. In the further description of the present invention to simplify the plot of the hub node will be called the hub 10 and will be leading to the hub, the hub of the steering wheel or the hub of the drive. Usually side direction is called the direction from the wheel inside the wheel hub, brake disc and the center of the vehicle, and the outboard direction is called the direction from the center of the vehicle out through the brake disc, hub and in the direction of the wheel. The inward call radial direction to the axis of the hub, and the outward call of the radial direction of the t axis of the hub.

We now turn to a consideration of figure 1, showing the wheel hub 10, which is concentrically fixed brake disc 12. The hub 10 has a housing 11 of generally cylindrical shape having an inner hole 14 for mounting to the bridge (not shown) and in the whole hollow interior space 16 of the hub 10. The disk 12 is fixed by means of fasteners 32, coming from the outboard side of the flange 18 of the hub inside to enter into engagement with the disc 12. Pins 72 extend in the outboard direction from the flange 18 of the hub and serve to mount the wheels (not shown) on the hub 10. Fasteners 32 disk and stud 72 for fastening the wheel mounted on the hub 10 on the first initial diameter of a circle from the axis 19 of the hub.

We now turn to a consideration of figure 2, showing the flange 30 of the disk, adapted for attachment to the flange 18 on the hub 10 of the wheel. The flange 30 of the disk attached to the flange of the hub 18 by means of threaded fasteners 32 for mounting the drive, passed through the flange 18 of the hub and put on the thread (screw) in the flange 30 of the disk. The flange of the disk group has projecting pins 47 to enter fasteners 32, which allow you to have access to the pins 72 of the wheel on the side side of the hub flange. Studs 72 wheels have a head portion (head) 73, resting in the flange 18 of the hub.

As shown in figure 2 concentric guiding device 49 of the disc contains a plot of the hub and the disk area. The plot of the hub contains many guides tides 50 hub formed circumferentially around the flange 18 of the hub. Each of the guides of the tides hub 50 is formed on the second initial diameter of a circle about the axis 19 of the hub 10. Smart surge of hub 50 is formed in a position radially outside relative to the mounting holes 44 (Fig 3) drive. Smart surge of hub 50 is in the on-Board direction from the surface 36 of the hub flange. Each guide tide hub engages with the pin 47 on the flange of the disk. It should be borne in mind that the guides tides hub 50 can be located so as to engage with three or more alternating spokes 47, or alternatively surge 50 can be formed so as to engage with one pin depending on the design characteristics of the device. Each of the guides of the tides 50 hub contains the running radially inward thickening 52 to enter into engagement with the outer edge 66 of the flange 30 of the disk. A guiding device 49 is formed between the outer edge 66 and the tide 50 and is used for concentric alignment (alignment) of the disk 12 with the hub 10.

We now turn to a consideration of figure 3, which shows part of the engagement with the brake disk 26, which is connected with the cylindrical sleeve 28 and the flange 30 of the disk, and the current output from the sleeve 28. The flange 18 of the hub has an outboard surface 34 and the side surface 36. The flange 18 of the hub has a smooth generally tapered side section 42 and a smooth outer surface 22 of the hub. The hole 44 in the pin 47, which serves for the installation disk, adapted to enter it on the thread (for driving) fasteners 32, which is intended for fastening of the disk 12 on the hub 10. The hole 44 for mounting the disk is located at the first initial diameter of a circle about the axis 19 of the hub 10. Surge 50 is located on the second diameter of the starting circle offset radially outward from the first diameter of the starting circle. First, the initial diameter of the circle is between the second diameter of the starting circle and the axis 19. Surge 50 is engaged with the flange 30 of the disk at the outer edge 68 (figure 4) radially outside from the hole 44 of the disk. Each burst 50 is formed on the second initial diameter of a circle about the axis 19 of the hub. First, the initial diameter of the circle is between the second diameter of the starting circle and the axis 19. The second diameter of the initial circumference greater than the first diameter of the starting circle.

As shown in figure 3, the side section 42 of the hub has an additional side surface 60 of the hub flange, designed for flange mounting of the disk, the processing is nnow on the machine so that it is perpendicular to the axis 19. The flange 30 of the disk has an outboard surface 62 of the flange disc, machined so that it is perpendicular to the axis 19, which is intended to enter into engagement with a side surface 60 of the hub flange. The flange 30 of the disk has many holes 46 of the disk, formed on the first initial diameter of a circle about the axis 19 and aligned (aligned) with holes 44 for the installation disk. The flange 30 of the disk drive further comprises an outer edge 66 of the flange of the disk, which ends the guide surface 68 of the hub. Guide surface 68 of the hub is located on the second diameter of the starting circle and is precisely machined to log in engagement with the guide surface 56 for the drive to concentrically to combine the disk 12 with the hub 10 of the wheel.

Side surface 60 of the hub flange rests against the outboard surface 62 of the flange of the disk to align along the axis of the disk with the hub 10. In accordance with the first variant of the device guide surface 56 of the disc on the hub is included in ovative the General engagement with the disc 12. It should be borne in mind that when the disk 12 is attached to the hub 10, no additional load is not applied between the disc 12 and the hub 10 in the guiding device.

Figure 3 shows the surface of the flange section 18 of the hub and flange 30 of the disk, where you can see the installation of the stud 72 of the wheel. Mounting stud wheel 72 is pressed into the hole 79 in the flange 18 of the hub, which is mainly formed on the first initial diameter of the circle. Mounting stud wheel 72 is held using a slotted section 76 of the housing 78 of the stud which is engaged with the flange 18 of the hub. The housing 78 of the stud further comprises a flange (head) 80, which is engaged with the flange rests on the flange 18 to the hub. A guiding device 49 concentrically aligns the disk 12 with the hub 10.

We now turn to a consideration of figure 4, which shows thickening 52 on the tide 50, which is processed on the wall to form a guide surface 56 for the disk and the cavity 58. Surge 50 is on the axis side direction and forms a foot 54 to form a precisely machined guide surface 56 for a disk located on the second diameter of the starting circle and designed for concentric alignment of the disc 12 with the hub 10 of the wheel. The disk 12 has a guide surface 68 to access the s on the outer edge 66.

As shown in figure 4, a guiding device 49 includes a guide surface 56 to the drive, which is included in covering engagement with the disc 12 through engagement with the guide surface 68 of the hub. The hub 10 is attached to the disc 12 by means of fasteners 32, buried in the outboard surface 34, passed through a hole 46 and put on the threads in the flange 30 of the disk on the spindle 47. Smooth surface 42 of the hub goes to the surface 60 of the hub flange, which is adjacent to the surface 62 of the flange of the disk. The outer surface 22 on the hub 10 forms the outer perimeter of the unit hub disk.
