Abstract
A safety support designed to be inserted by a translation operation around a rim bearing in which the radially inner surface of the base of the support contains a plurality of protuberances radially arranged internally.
Claims21
A safety support designed to be inserted by a relative translation operation on a wheel rim bearing, said support having an axially front face and an axially back face and containing a base intended to fit around said bearing as well as a body connected to said base, said bearing having an engagement edge and said translation operation consisting of moving the engagement edge of the rim bearing from said axially front face of the support toward said axially back face, wherein the radially lower surface of the base of the support presents a plurality of circumferentially distributed centering protuberances and wherein the radially inner walls of which are inscribed in free state on a diameter less than the diameter of the rim support bearings.
A safety support designed to be inserted by a relative translation operation on a wheel rim bearing, said support having an axially front face and an axially back face and containing a base intended to fit around said bearing as well as a body connected to said base, said bearing having an engagement edge and said translation operation consisting of moving the engagement edge of the rim bearing from said axially front face of the support toward said axially back face, characterized in that the radially lower surface of the base of the support presents a plurality of circumferentially distributed centering protuberances, each of said centering protuberances possessing in section through an axial plane a portion of a radially inner profile, whose distance from the axis of the support gradually diminishes in the axial direction between a value exceeding the radius of the engagement edge of the rim bearing on the side of the axially back face of the support and a value less than that radius toward the side of the axially front face of the support.
