Problems solved by technology

[0005] However, even if an axial spring is provided to prevent the rollers from tilting, if the rollers tilt slightly while moving from the damping point to the reference point, the outer peripheral portion of the second end surface of the rollers will be hooked on the cage. On the side, there is a possibility that the rollers are inclined at the reference point to prevent the smooth engagement of the one-way clutch, or the outer peripheral part of the second end surface of the rollers and the side surface of the cage rub against each other and become a cause of wear

Embodiment Construction

[0031] Below, according to Figure 1 to Figure 12 Embodiments of the present invention will be described.

[0032] Such as Figure 1 ~ Figure 3 As shown, the vehicle power transmission device that transmits the driving force of the engine E to the driving wheels W, W via the left and right axles 10 , 10 includes a crank-type continuously variable transmission T and a differential gear D. As shown in FIG. The continuously variable transmission T of this embodiment is obtained by superimposing a plurality of (four in the embodiment) power transmission units U having the same structure in the axial direction, and these power transmission units U have a common input arranged in parallel. The shaft 11 and the output shaft 12 are common, and the rotation of the input shaft 11 is decelerated or accelerated to be transmitted to the output shaft 12 .

[0033] Below, according to Figure 2 ~ Figure 6 The structure of the continuously variable transmission T will be described.

Abstract

The present invention provides a one-way clutch and crank type continuously variable transmission which prevents the outer peripheral portion of the end face of the roller biased in the axial direction by the axial spring from engaging the side surface of the cage. Since the frictional force acting on the first end surface (25a) of the roller (25) is consistent with the frictional force acting on the second end surface (25b) of the roller (25), it is possible to suppress the roller (25) from When the point moves to the meshing point, the first and second end surfaces (25a, 25b) of the roller (25) that prevent inclination and the inner ring The first side (36a) and the second side (36b) of (36) contact and wear, and can make the roller (25) smoothly engage into the outer peripheral surface (23a) of the inner part (23) and the outer part (22) The engagement responsiveness of the one-way clutch (21) is improved between the inner peripheral surfaces (22a) of the one-way clutch (21).

Description

technical field [0001] The present invention relates to a one-way clutch in which a plurality of rollers held on a cage are urged in a circumferential direction using an engaging spring, and a crank type continuously variable transmission having the same. The cage is disposed between the outer peripheral surface of the inner member and the inner peripheral surface of the outer member, and the rollers are engaged with the outer peripheral surface and the inner peripheral surface of the outer member by relative rotation of the inner member and the outer member in one direction. The driving force is transmitted between the inner peripheral surfaces. Background technique [0002] According to the following patent document 1, it is known to use a coil spring to form an engaging spring that biases the rollers of the one-way clutch in the circumferential direction, and to provide a mechanism for restricting the axial displacement of the coil spring at the cage holding the rollers. ...
