Abstract
The torque transmitting connecting element, for example constituted by a flange, comprises a small number of pairs of bearing planes which are angularly spaced apart. The two planes of each pair are convergent in a direction away from the connecting face of the element and constitute the two flanks of a channel or of a projection which has a constant trapezoid cross-sectional shape which is symmetrical relative to a plane containing the axis of rotation of the element. Such elements, when they are interconnected in a torque-transmitting device, cooperate solely by their pairs of bearing planes. Bolts or a nut clamp these two elements together. The invention is for example applicable to automobile vehicle transmissions.
Claims12
A connecting element for a transmission, the element having an axis of rotation and a face adjacent to which a structure is to be connected, the element defining a small number of pairs of bearing planes and an intermediate plane between each pair of planes, the two bearing planes of each pair being convergent in a direction away from said face of the element and facing axially outwardly of the element and forming two flanks of a channel or of a projection which has a constant trapezoid cross-sectional shape which is symmetrically relative to a radial plane containing the axis of rotation of the element neighbouring pairs of bearing planes being angularly spaced apart and a bolt aperture being provided in said intermediate plane between each pair of bearing planes and stopping short of the respective pair of bearing planes transversely of the intermediate plane.
A metal connecting element for a transmission, the element having an axis of rotation and a face adjacent to which a structure is to be connected, the element defining a small number of pairs of bearing planes and an intermediate plane between each pair of planes, the two bearing planes of each pair being convergent in a direction away from said face of the element and facing axially outwardly of the element and forming two flanks of a channel or of a projection which has a constant trapezoid cross-sectional shape which is symmetrically relative to a radial plane containing the axis of rotation of the element, neighbouring pairs of bearing planes being angularly spaced apart, a bolt aperture being provided in said intermediate plane between each pair of bearing planes and stopping short of the respective pair of bearing planes and stopping short of the respective pair of bearing planes transversely of the intermediate plane, the element being constituted by a generally planar flange, the thickness of the flange being substantially uniform throughout the flange, and said bearing planes and intermediate planes being the result of an upsetting and a work-hardening of the metal of the flange by a press operation.
A connecting device for a transmission, comprising two connecting elements, each element having an axis of rotation and a face adjacent to which face the other element is to be connected in coaxial relation, each element defining a small number of pairs of bearing planes and an intermediate plane between each pair of bearing planes, the two bearing planes of each pair being convergent in a direction away from said face of said each element and facing axially outwardly of said each element and forming two flanks of a configuration of the element which has a constant trapezoid cross-sectional shape which is symmetrically relative to a radial plane containing the axis of rotation of said each element, neighbouring pairs of bearing planes being angularly spaced apart and a bolt aperture being provided in said intermediate plane between each pair of bearing planes and stopping short of the respective pair of bearing planes transversely of the intermediate plane, said two elements being in engagement solely by their pairs of bearing planes, the flanks of one of said elements defining channels and the flanks of the other of said elements defining projections engaged in the channels, bolts for axially clamping said two elements against each other, said bolts extending through the bolt apertures pertaining to the interengaged projections and channels, and means defining nuts being screwthreadedly engaged on the bolts.
