Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a wheel cap bracket, and more particularly to a wheel cap bracket for an automobile having an all-floating axle.

<Prior Art> For a vehicle equipped with a fully floating axle, for example,
As shown in the figure, a flange 3 is provided on the shaft end of an axle shaft 2 protruding from the axle housing 1.
Then, the flange 3 is formed on the outer end surface of the wheel hub 5 axially attached to the axle housing 1 via a bearing 4.
The axle shaft 2 and the wheel hub 5 are connected to each other by superimposing the peripheral edges of the above and fastening and fixing them with bolts 6. Reference numeral 7 is a brake drum, 8 is a wheel disc, and 9 is a tire.

Further, in order to improve aerodynamic characteristics or appearance of automobiles, wheel caps are sometimes attached in recent years. When mounting such a wheel cap 10, conventionally, as shown in FIG. 7, a tightening surface 11a of the wheel cap 10 is formed on the bottom surface and the outer diameter of the opening 3 is substantially the same as the outer diameter of the flange 3. Cup-shaped bracket 11 with a ring-shaped mounting flange 11b
The mounting flange 11b of the bracket 11 is superposed on the surface of the flange 3 as shown in FIGS. 5 and 6, and these are fastened together with the end face of the wheel hub 5 by a plurality of bolts 6. I was doing.

Therefore, to attach the wheel cap 10, bolt 6
If the flange 3 (axle shaft 2) is detached by removing the flange 3 and the wheel hub 5 from each other, the oil in the housing 1 may leak out.

That is, in an all-floating axle, for example, as shown in FIG. 6, the outer peripheral edge of the oil seal 12 is sandwiched between the joints of the flange 3 and the wheel hub 5, and the oil seal 12
The oil in the housing 1 is prevented from leaking out by sliding the inner peripheral edge of the outer peripheral surface of the housing 1 in the vicinity of the end portion of the housing 1. For this reason, when the bolt 6 is pulled out and the coupling between the flange 3 and the wheel hub 5 is released, the sealing action of the oil seal 12 is no longer guaranteed and oil dripping may occur.

<Problems to be Solved by the Invention> The present invention has been made in view of the above, and it is possible to prevent the oil dripping at the time of attaching and detaching the bracket, and to secure the support ability of the wheel cap and the workability of attaching and detaching the wheel disc. It is intended to provide an automobile wheel cap bracket.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a bolt on a mounting flange formed in a ring shape having an outer diameter substantially the same as that of a flange formed on the shaft end of an axle shaft. A part of the facing position of the bolt is recessed outward in the axial direction of the axle shaft to form a recess for avoiding interference with the head of the bolt, and the facing part of the bolt excluding the recess is formed. The feature is that each position has a bolt hole.

<Operation> Therefore, the bracket is jointly fastened to the wheel hub together with the flange of the axle shaft by the bolt not facing the recess, and the bolt facing the recess only fixes the flange of the axle shaft to the wheel hub.
For this reason, it is not necessary to remove all the bolts to disconnect the flange of the axle shaft from the wheel hub even when mounting the bracket, and leave the bolt facing the recess and the flange and the wheel hub. Since it is possible to hold the oil and the oil to continue the sealing action by the oil seal, the oil dripping that is conventionally seen is prevented. Further, since the mounting flange of the bracket is kept ring-shaped and the recess is provided so as to avoid interference with the remaining bolts, the rigidity of the mounting flange is not impaired and the wheel cap of the wheel cap is not impaired. Support function is secured. Further, since the mounting flange of the bracket is recessed outward in the axial direction of the axle shaft to form a recess for avoiding interference with the head of the bolt, the outer diameter of the mounting flange is increased. Therefore, there is no need to avoid interference with the bolts, and the workability of attaching and detaching the wheel disk does not deteriorate.

<Embodiment> An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 4. In the drawings, parts having substantially the same functions as those of the conventional example shown in FIGS. 5 to 7 are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 is a perspective view showing an embodiment of a wheel cap bracket according to the present invention, FIG. 2 is a side view of the bracket, FIG. 3 is a front view of a mounting flange, and FIG. 4 is a recess and a bolt. FIG. 3 is a perspective view showing the relationship between the bracket 11 and the ring-shaped attachment to the opening edge of the cup-shaped bracket 11 whose bottom surface is a tightening surface 11a for fixing the back surface of the center portion of the wheel cap 10 not shown. A flange 11b is provided. The outer diameter of the mounting flange 11b is substantially the same as the outer diameter of the flange 3 provided at the shaft end of the axle shaft 2 (not shown) as in the conventional one, and is mounted on the surface of the flange 3. The flanges 11b are overlapped and these are fastened and fixed to the end surface of the wheel hub 5 not shown by bolts.

Further, the recess 11c that is recessed outward in the axial direction of the axle shaft 2 has a phase of 180 ° at the mounting flange 11b.
By providing the bolts 6 at two positions on different diagonals, interference between the heads of the two bolts 6 located diagonally and the mounting flange 11b is avoided by the recesses 11c, 11c.

That is, the bolt 6 facing the recess 11c is attached to the mounting flange 11b.
The mounting flange 11b is fixed to the wheel hub 5 together with the flange 3 of the axle shaft 2 only by the bolt 6 that does not face the recess 11c and does not participate in the tightening. Therefore, for example, even when mounting the bracket 11, there is no need to remove all the bolts 6 to release the connection between the flange 3 of the axle shaft and the wheel hub 5, and the bolts 6 facing the recess 11c are left. Since the connection between the wheel hub 5 and the wheel hub 3 can be maintained and the sealing action of the oil seal 12 can be continued, oil dripping as has been seen in the past can be prevented. Also, while maintaining the mounting flange 11b of the bracket 11 in a ring shape,
Since the recess 11c is provided to avoid the interference with the bolt 6 which is left to prevent the oil from dripping, the rigidity of the mounting flange 11b is not impaired. Further, since the mounting flange 11b is recessed outward in the axial direction of the axle shaft 2 so as to avoid interference with the bolt 6, the outer diameter of the mounting flange 11b is increased and the mounting flange 11b There is no need to avoid interference, and the workability of attaching and detaching the wheel disc 8 does not deteriorate.

In the embodiment, the recesses 11c are provided at two positions on the mounting flange 11b so as to face the two bolts 6 located diagonally, and the degree of freedom in the mounting direction of the bracket 11 is increased. However, the number of the recesses 11c can be arbitrarily changed according to the number of bolts 6 or the strength thereof. Further, as shown in the embodiment, when the leg 11e of the bracket 11 for connecting the tightening surface 11a of the wheel cap 10 and the mounting flange 11b is provided in the recess 11c, the leg 11e is recessed. The rigidity of the bracket 11 is increased because the rigidity of the bracket 11 can be increased by shortening the height of the wheel 11c, but the joint structure between the fastening surface 11a of the wheel cap 10 and the mounting flange 11b is not limited to the embodiment.

<Effect of the Invention> As is apparent from the above description, according to the present invention, the mounting flange of the wheel cap bracket is clamped and fixed by using only a part of the bolt for clamping and fixing the flange of the axle shaft to the wheel hub. However, the relief for the remaining bolts not involved in the tightening is formed by the recess provided in the mounting flange.

For this reason, the bracket can be attached and detached by removing only the bolts involved in the tightening of the bracket while leaving the bolts facing the recess, so that it is necessary to remove all the bolts when attaching and detaching the bracket. It can prevent oil leakage.

Further, since the mounting flange is recessed outward in the axial direction of the axle shaft to form a clearance with the bolt, it is necessary to change the inner diameter or the outer diameter of the mounting flange to form the clearance. Instead, it can be applied to existing ones as it is, and it is possible to prevent deterioration of rigidity of the bracket and deterioration of workability of attaching and detaching the wheel disc.
