Embodiment Construction

[0065] Embodiments of the present invention will be described below based on the drawings.

[0066] Figure 1A A partial longitudinal sectional view showing a fixed type constant velocity universal joint 1 (hereinafter also simply referred to as "constant velocity universal joint 1") according to the first embodiment of the present invention, Figure 1B Show the front view of the constant velocity universal joint 1 ( Figure 1A right side view of the ). This constant velocity universal joint 1 mainly includes an outer joint member 2 , an inner joint member 3 , balls 4 , and a cage 5 .

[0067] also like Figure 2A , 2B As shown, eight raceway grooves 7 extending in the axial direction are formed on the spherical inner peripheral surface 6 of the outer coupling member 2, and each raceway groove 7 is inclined in the circumferential direction relative to the axis N-N of the coupling Angle γ, and the inclination directions of the circumferentially adjacent track grooves 7, 7 ...

Abstract

According to the present invention, the track groove (7) of an outside joint member (2) comprises first track groove parts (7a) and second track groove parts (7b). The first track groove parts (7a) have an arc shape that has a center of curvature at a position offset toward the opening in relation to the center of the joint, and are inclined in the circumferential direction with respect to the axial line N-N of the joint, and the first track groove parts (7a) adjacent to each other in the circumferential direction are formed so as to be inclined in opposite directions to each other. The second track groove parts (7b) have a linear portion in order to increase the effective track length with respect to the maximum operating angle, and are connected to the first track groove parts (7a) on the side further toward the opening than the joint center (O). The track groove (9) of the inside joint member (3) is formed with mirror symmetry relative to the track groove (7) of the other outside joint member (2) that constitutes a pair of outside joint members, the symmetry being about the joint center plane (P) at an operating angle of 0°.

Description

technical field [0001] The present invention relates to a fixed type constant velocity universal joint, in particular, to a fixed type constant velocity universal joint used in the power transmission system of motor vehicles and various industrial machines between two shafts on the driving side and the driven side Fixed constant velocity universal joints that allow angular displacement only. Background technique [0002] For example, on the front drive shaft of a motor vehicle, a sliding constant velocity universal joint with a relatively small maximum operating angle but capable of axial displacement while having an operating angle is usually assembled on the inner side (differential side). , A fixed constant velocity universal joint with a large working angle due to wheel steering but no axial displacement is assembled on the outer side (wheel side). [0003] based on Figure 19A The shown longitudinal sectional view of the constant velocity universal joint 101 in a state...
