Definitions
- the present invention relates to a hub unit for a vehicle.
- a hub unit has been used as a vehicle that supports a vehicle wheel rotatably with respect to a suspension device.
- this hub unit includes a rolling bearing and a flange portion provided integrally with a ring member of the rolling bearing.
- the flange is formed with a plurality of bolt holes for attaching parts such as wheels and disk rotors. These bolt holes penetrate through the flange portion in the thickness direction.
- a single bolt hole group having a hole pattern in which a plurality of bolt holes having the same hole diameter are evenly distributed in the circumferential direction of the flange portion is formed in the flange portion of the hub unit.
- the hub unit as described above, there are many parts such as wheels and disk rotors attached to the flange portion that differ in hole pattern from the flange portion depending on the manufacturer and vehicle type. Specifically, the hole diameters of bolt holes formed in the parts are different in pitch circle diameter. On the other hand, the bolt hole group formed in the flange portion is singular and is composed of only one type of hole pattern. In other words, the parts that can be attached to the flange were limited to those having one kind of hole pattern. For this reason, in the conventional hub unit, it was necessary to prepare multiple types to accommodate parts with different hole patterns. However, this is not preferable in terms of production efficiency of the hub unit. Therefore, as described in Japanese Patent Application Laid-Open No. 2001-150901, between a flange portion to which a plurality of types of parts having different hole patterns are attached to one type of hub, and a component to be attached thereto. A knob unit with an adapter inserted has been proposed.
- the hub unit requires an adapter that is a separate member from the hub unit. For this reason, There is a problem that the number of parts of the block unit increases, resulting in an increase in cost.
- the present invention has been made in view of the above problems, and an object thereof is to provide a low-cost hub unit capable of attaching a plurality of types of parts having different hole patterns without using different members.
- the vehicle hub unit of the present invention includes a rolling bearing and a flange portion that is provided on the bearing ring member of the rolling bearing, and the flange portion penetrates the flange portion in the thickness direction.
- the plurality of bolt holes are respectively formed with female threads
- the flange portion has the plurality of the same nominal diameters of the female threads.
- a plurality of bolt hole groups having a hole pattern in which the bolt holes are evenly distributed in the circumferential direction on the same pitch circle diameter are formed, and the plurality of bolt hole groups have a nominal diameter of the female screw or the pitch circle diameter. It is characterized by at least one being different.
- a plurality of bolt hole groups having a hole pattern are formed in the flange portion, and at least one of the nominal diameter or pitch circle diameter of the female screw is different between these bolt hole groups.
- a plurality of hole patterns are formed. Accordingly, since a plurality of types of parts having different hole patterns can be directly attached to the flange portion without using an adapter that is a separate member as in the prior art, a low-cost hub unit can be configured.
- all bolt holes constituting the plurality of bolt hole groups are equally distributed in a circumferential direction of the flange portion.
- the bolt holes are not concentrated at one place in the circumferential direction of the flange portion. . Therefore, it is possible to sufficiently ensure the strength of the flange portion and to prevent a decrease in rotational accuracy due to a disturbance in weight distribution.
- FIG. 1 is a partial cross-sectional view of a hub unit.
- FIG. 2 is an arrow view showing the A direction force in FIG. BEST MODE FOR CARRYING OUT THE INVENTION
- FIG. 1 shows a hub unit 1 according to an embodiment of the present invention
- FIG. 2 shows a state of looking at A force in FIG.
- the left-right direction in FIG. 1 is referred to as the axial direction of the hub unit 1, the left side in the figure is referred to as the axially outer side, and the right side is referred to as the axially inner side.
- the hub unit 1 is for supporting the wheels of an automobile in a self-rotating manner with respect to a suspension device.
- the hub unit 1 includes a rolling bearing 3, a cylindrical hub wheel 2 serving as a bearing ring member of the rolling bearing 3, and an annular flange portion 4 provided integrally with the hub wheel 2.
- the flange portion 4 is formed with a plurality of bolt holes 5 for attaching components (not shown) such as a wheel and a disk aperture.
- an annular portion 6 that protrudes outward in the axial direction is provided at the center of the flange portion 4.
- the hub wheel 2 is composed of a carbon steel (S55C), a bearing steel, or the like.
- the small-diameter portion 7 having a circular cross section and the axially inner end of the small-diameter portion 7 are bent radially outward.
- a deformed caulking portion 8 and a large-diameter portion 9 having a circular shape in section and continuously provided from the small-diameter portion 7 toward the outer side in the axial direction are provided.
- the flange portion 4 is provided in the large-diameter portion 9 of the hub wheel 2 so as to extend outward in the outer circumferential surface force radial direction.
- the rolling bearing 3 is, for example, a double row ball bearing so that the outer ring 12 having a pair of outer ring raceway surfaces 11a and l ib and the inner peripheral surface are in close contact with the outer peripheral surface 7a of the small diameter portion 7 of the hub wheel 2. And an inner ring member 13 fitted thereto.
- the inner ring member 13 is provided with an inner ring raceway surface 14a facing the outer ring raceway surface 1 lb on the inner side in the axial direction on the radially outer side.
- the outer peripheral surface of the large diameter portion 9 of the hub wheel 2 is An inner ring raceway surface 14b opposite to the outer outer ring raceway surface 11a is provided.
- a pair of balls 15 which are rolling elements arranged so as to be able to roll on inner and outer ring raceway surfaces facing each other, and these balls 15 are respectively held at predetermined intervals in the circumferential direction.
- a pair of retainers 16 are provided.
- the rolling bearing 3 is an outer peripheral surface of the outer ring 12.
- the annular flange formed between the hub wheel 2 and the outer ring 12 is sealed from both ends in the axial direction, and the bearing flange 18 that extends radially outward and to which the knuckle (not shown) of the steering mechanism is fixed. And a seal member 19.
- the plurality of bolt holes 5 are formed so as to penetrate the flange portion 4 in the thickness direction, and female threads are formed on the respective inner peripheral surfaces.
- the flange portion 4 is formed with a plurality of bolt hole groups H force having a hole pattern.
- the hole pattern is a pattern in which a plurality of bolt holes 5 each having the same nominal diameter of the female thread are evenly distributed in the circumferential direction on the same pitch circle diameter (pitch diameter) R! Uh.
- the plurality of bolt hole groups H are different from each other in at least one of the nominal diameter of the female screw of the bolt hole 5 constituting the bolt hole group H or the pitch circle diameter R. It is comprised so that. All the bolt holes 5 constituting the plurality of bolt hole groups H are equally distributed in the circumferential direction of the flange portion 4. Specifically, bolt hole groups H1 to H3 having three types of hole pattern forces are formed in the flange portion 4, for example. Each of these bolt hole groups H1 to H3 includes, for example, five bolt holes 5. The 15 bolt holes 5 constituting these bolt hole groups H are equally distributed in the circumferential direction of the flange portion 4.
- the bolt hole group HI that also serves as the first hole patterner has a nominal diameter of the female screw of the bolt hole 51 of 12 mm and a pitch diameter of the pitch circle R1 is formed to 114.3 mm.
- the bolt hole group H2 composed of the second hole pattern is formed such that the nominal diameter of the female screw of the bolt hole 52 is 12 mm and the pitch circle diameter R2 is 120 mm.
- the bolt hole group H3 including the third hole pattern is formed such that the nominal diameter of the female screw of the bolt hole 53 is 14 mm and the pitch circle diameter R3 is 112 mm. Then, all the bolt holes 51, 52, and 53 constituting the first to third bolt hole groups H1 to H3 are equally distributed in the circumferential direction of the flange portion 4, respectively.
- the wheel and the disc rotor are pressed against the outer surface 4 a of the flange portion 4 so as to overlap in the axial direction. Then, position adjustment is performed so that the bolt holes 5 of the bolt hole cover portions 4 of the wheel and the disc rotor are aligned. After adjusting, adjust the internal thread of bolt hole 5. Use a bolt with the same nominal diameter as the nominal diameter and tighten the wheel axially outward force.
- a plurality of bolt hole groups H having a hole pattern are formed in the flange portion 4, and the nominal diameter of the female screw or the pitch circle is formed between these bolt hole groups H. Since at least one of the diameters R is different, a plurality of hole patterns are formed in the flange portion 4. Therefore, as in the prior art, it is possible to directly attach a plurality of types of parts such as wheels and disk wheels having different hole patterns to the flange portion 4 without using an adapter which is a separate member. Further, the hub wheel 2 is further reduced in weight by forming a plurality of bolt hole groups H1 to H3 in the flange portion 4. As a result, the unsprung weight in the suspension system of the automobile is reduced, and the running stability, ride comfort and fuel consumption can be improved.
