Problems solved by technology

[0012] In addition, the serration shaft 8b of the outer joint member 7a is detachably connected to the hub wheel 3 by using a stop ring, and the radial gap between the hub wheel 3 and the serration shaft 8b is sealed by a sealing member. structure (Japanese Patent Application No. 2000-142009), but due to the gap between the above-mentioned butt joint surfaces, it is different from such Figure 14 The nut fastening structure shown is much larger than that, so a firm sealing member must be installed. While increasing the cost, it cannot prevent the decrease in the rigidity of the entire device, so it is not ideal

Embodiment Construction

[0060] The following is based on Figure 1 to Figure 11 Embodiments of the present invention will be described. In addition, in the following description, in the assembled state of the vehicle, the side closer to the outer side of the vehicle is referred to as the outer side, and the side closer to the center of the vehicle is referred to as the inner side. exist figure 1 , image 3 , Figure 4 , Figure 6 ~ Figure 11 In the middle, the left side is the outer side, and the right side is the inner side.

[0061] figure 1 It is a bearing device for driving a wheel, and is configured by inserting a plurality of rows of rotating bodies 50 between an outer member 10 fixed to the vehicle body and an inner member 20 driven to rotate, and supporting the inner member 20 rotatably. The multi-row rotors 50 are held at equal intervals in the circumferential direction by cages 60 made of synthetic resin, are additionally mounted between the multi-row outer ring 11 and the inner rin...

Abstract

The invention relates to a bearing device for driving wheel. An end of a hub wheel 30 is plastically deformed towards outside diameter, a riveting portion 37 along radius direction is formed, and the hub wheel 30 and an inner wheel 40 arranged on periphery of the hub wheel are integrated. An outside shaft coupling component 72 of a constant velocity universal coupling 70 is pressed in bore of thehub wheel 30, and serrations 81 on bore of the hub wheel 30 is matched with a serration shaft 82 of the outside shaft coupling component 72. The length of the serrations 81 on bore of the hub wheel 30 along axial direction is in a standard range, and radius reducing of the serrations 81 associated with riveting is reduced.

Description

[0001] This application is a divisional application dated March 25, 2002, application number 02800886.3, and the title of the invention is "Bearing device for driving wheels" (divisional application submission date is February 12, 2007, application number is 200710080108.6) Apply. technical field [0002] The present invention relates to the freely rotatable support of the driving wheels (rear wheels of FR (front-engine rear-wheel drive) cars) of automobiles, etc. relative to the vehicle body, front wheels of FF cars (front-engine front-wheel drive), 4WD (four-wheel drive) ) Bearing device for all wheels of the car. Background technique [0003] Various types of bearing devices for drive wheels of automobiles have been proposed according to their applications. For example, Figure 12 The shown bearing device for driving a wheel has a structure in which the hub wheel 3 and the multi-row bearing portion are unitized into one bearing, and the outer joint member 7a of the const...
