的とするものである。DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION The present invention relates to a mounting structure of an axle for transmitting driving force in a vehicle and a hub for mounting wheels and brakes, and durability of the mounting. The purpose is to improve the performance.

角度を共に同角度としたものであつた。Conventional technology For mounting a hub on an axle, conventionally, the axle was generally supported on a knuckle via a wheel bearing, and after inserting a collar on the axle, the hub was meshed with a spline, and further, a cone washer was fitted. Later, these members were tightened and integrated with a nut at a screw portion at the tip of the axle. In order to reduce vibration and wear, it is necessary to make the hub and axle firmly connected and concentric, and a cone washer is used, and by tightening the nut, the tapered portion on the outer periphery of the cone washer In this case, the axle and the hub are tightly connected to each other by being in close contact with a cut-out portion formed on the inner peripheral side of the end face to secure concentricity. In particular, conventionally, in order to obtain close contact between the outer peripheral tapered portion of the cone washer and the cut-out tapered portion of the hub, the conical angles of the tapered portions are made the same.

乏しかつた。However, if the cone angle between the cone washer outer peripheral taper portion and the cut-out inner peripheral taper portion of the hub is the same, the coupling force is loosened by external force, resulting in durability. Scarce.
そこで、締付けの耐久性を保持する為にコーンワツシ

つた。So, in order to maintain the durability of the tightening, there was a thing that put a disc spring washer between the cone washer and the nut to bring about a spring action, but then the disc spring washer itself was a special part and cost increased, In addition, it is required to set an axle with a longer height of the disc spring washer, and even if the axle alone is considered, the weight increases, and in practice it is insignificant, but it is disadvantageous in terms of cost. In addition, the use of disc spring washers also affected related parts such as the shape of the wheel cap.

る。Means for solving the problem In the present invention, the conical angle of the tapered portion of the cone washer having both ends present on the same plane and having slits is made larger than the conical angle of the tapered portion of the inner periphery of the hub,
A spring action is generated against a thrust load to maintain durability. In other words, if the cone angle of the cone washer is larger than the cone angle of the hub, the cone washer contracts in the radial direction until the tapered surfaces coincide with each other, causing a twist and a spring action occurs. It is because it will be.

２度大きくするものである。As shown in FIG. 1, after a collar is inserted into an axle 3 supported on a knuckle 1 via a wheel bearing 2 as shown in FIG. 1, a hub 5 is spline-coupled to a screw portion 3a at the tip of the axle. With respect to a method in which the hub is fastened to the axle by tightening the nut 6, the tapered portion 5a cut out from the end face of the hub to the inner circumference is pressed and adhered by the tapered portion 7a on the outer periphery of the cone washer 7 to the axle. Conical angle (α) of outer peripheral taper 7a
Is larger by 1 or 2 degrees than the cone angle (β) of the inner peripheral tapered portion 5a of the hub.

いてスプリング作用を生ぜしめるものである。As shown in FIG. 2, the cone washer 7 has both end edges on the same plane and has a slit 7b to generate a spring action.
なお、図中、８は平ワツシヤである。 In the figure, reference numeral 8 denotes a flat washer.

力で維持されることになる。Then, after the collar 4 is inserted into the axle 3 supported by the wheel bearing 2 on the nut 1, the hub 5 is spline-engaged, and these members are tightened by the nut 6 via the cone washer 7. At the time of the tightening, a tightening force is generated by screwing of the nut, and at the same time, the cone washer 7 is tightened from the outer periphery by the inner peripheral taper portion 5a of the hub, and the force acts on the axle 3 as a frictional force. However, the frictional force is gradually released by an external load such as a wheel, and finally decreases to only the tightening force.
The result is a clamping force that is truly effective and invariant for joining the members such as the hub. Therefore, the tightening torque of the nut 6 is converted into a tightening force between the members that is as effective as possible.
It is important to maintain it. For this reason, it is necessary to increase the tightening torque of the nut, but this has limitations in terms of the anti-torsion strength and the tightening labor of the threaded portion 3a at the axle tip. Therefore, it is necessary to tighten with a tightening torque as high as the strength of the threaded portion allows and maintain it to the maximum. However, when the stiffness of the cone washer 7 is relatively high, the frictional force generated by the tightening torque is large, and when the frictional force is released by an external load, the frictional force is finally reduced from the tightening torque of the nut 6. It converges to the deducted tightening force. Conversely, when the rigidity of the cone washer is relatively low, even if friction acts, the cone washer is maintained at a tightening force close to the tightening load tightened by the nut.

心を容易に確保することも出来る。Therefore, when using a cone washer 7 in which the outer peripheral taper of the cone washer is cut off at the end of the hub and the conical angle is made larger than the inner tapered portion as in the present invention, when the cone washer is advanced by tightening the nut 6, the cone washer is itself moved. Since the slit 7b is cut, it shrinks in the direction of decreasing the diameter at the cut-out taper part of the hub, and further the force in the forward direction acts, causing the inside of the cone washer to twist and the spring action to work. In addition, since the rigidity is relatively low, effective tightening of the tightening load can be performed. Further, since both end edges of the cone washer 7 are present on the same plane and there is no displacement, concentricity between the hub 5 and the axle 3 can be easily secured.

とになつた。On the other hand, in the related art, since the outer tapered portion of the cone washer and the inner tapered portion of the hub have the same angle, the rigidity of the cone washer is relatively high, the spring action does not work, and even if the nut 6 is tightly tightened, The spline between the hub and the axle is worn out due to low tightening force due to external force applied during running, causing vibration and abnormal noise due to the increase of play clearance, especially when braking. It has become.

ことが出来たものである。Effect Since the present invention is as described above, usually, spline fitting is loose fitting from assembly, but it is difficult to secure concentricity of the hub, and it is easy to obtain it by using a cone washer, and The weak point of the wheel mounting structure is that the strong connection between the hub and the axle is impaired, and the most effective means of preventing this is to tighten the nut strongly, but the frictional force generated by the cone washer tightening The conical angle of the outer taper of the cone washer is made larger than the inner taper of the hub so that the nut can be held down. Is less affected by external forces transmitted to the hub from wheels, etc., and the durability has been significantly improved. It is.
