Abstract:
A method for making the composite material wheel rim includes the steps of: configuring a plurality of inner lining chunks individually to the desired position where the spokes are to be mounted to allow the inner lining chunks to be integrated with an inner annular portion of the wheel rim, next, integrating the formed inner annular portion with an outer annular portion of the wheel rim to form a semi-finished wheel rim, and then, creating the requested threaded holes for connecting the spokes in the inner lining chunks of the inner surface of the semi-finished wheel rim subject to the requested amount and angles of the spokes. By the present method, the semi-finished wheel rim allows drilled, threaded holes subject to needs to fit different types of wheel hub units to increase the yield rate and reduce the inventory of the wheel rims.
Abstract:
An assembly comprises a flange and a disc, wherein the disc has a brake band and a drum, said drum having an outer drum surface, said drum being suitable for receiving a bearing inside said drum, said disc being arranged between the bearing and said flange, and wherein the flange comprises an inner ring coupled with the disc and an outer ring able to be coupled with a wheel rim, said flange also comprising an intermediate portion having flange through openings defined by an opening edge, said opening edge comprises a radially most inner edge portion, wherein at least one portion of the outer surface of the drum of the disc is arranged radially outside of the edge portion of the flange opening arranged most radially inside.
Abstract:
A wheel rim having an axis of rotation, the rim including a first element in the form of a section of a solid of revolution about the axis, made in a single unitary piece from composite material and including a first end and a second end distinct from one another. The first element is made by pultrusion and constitutes, between the first end and the second end, a section of a solid of revolution having an angular arc greater than 350°, the composite material of the first element includes fibers embedded in a thermosetting matrix, the fibers constituting at least 50% of the weight of the first element.

Devices, such as medical devices for inhibiting conception, and methods of using and/or making these devices. In one aspect of the disclosure, a medical device has a delivery system and a first insert, which is removably coupled to the delivery system and which is designed to be deployed within a portion of a first fallopian tube, and a second insert, which is removably coupled to the delivery system and which is designed to be deployed within a portion of a second fallopian tube. Other aspects of the disclosure include, among other things, inserts made from one or more polymers; inserts which are designed to pierce and remain in place; and inserts which are implanted through a fluid delivery system.
Abstract:
A wheel having a recess thereon to offset the weight of a valve stem and/or a tire sensor so that the wheel will be balanced for normal operational use on a vehicle.
Abstract:
A rim (5) for a bicycle wheel having a body (20) with a substantially annular extension with a radially outer portion (22) shaped for coupling with a tire is disclosed. The radially outer portion (22) has a hole (39) for an inflation valve. The radially outer portion (22) also includes, at the hole (39) and/or in an area proximal to the hole (39), at least one cross section having a different shape from that at an area distal from the hole, so as to form at least one second surface discontinuity (35) along the annular extension of the radially outer portion (22). The second discontinuity (35) makes it easier to assemble to wheel and allows an optimal coupling to be made between the rim (5), inflation valve, and tire, in the case of a tubeless wheel, and between rim (5), air chamber and tire, in the case of a wheel with an air chamber.
Abstract:
The invention includes a rim for a cycle wheel, having a U-shaped radial cross section, with two lateral flanges and a bridge connecting the flanges and located so as to be opposite an axis rotation of the wheel. The flanges each define a planar braking surface, adapted to cooperate with a brake pad. The height of at least one braking surface, measured radially, is not constant over the circumference of the rim and has at least one variation in height.
Abstract:
A bicycle rim is basically provided with an outer rim portion and an inner rim portion. The outer rim portion has a ring shape of a first material. The inner rim portion is joined to the outer rim portion. The inner rim portion has a ring shape of a second material with an internal residual stress distribution resulting from the ring shape being formed by spinning of the second material.
Abstract:
A composite rim for a bicycle wheel generally includes a radially outer tire-engaging portion, a radially inner spoke-engaging portion and first and second sidewalls. The second sidewall is spaced apart from the first sidewall. The first and second sidewalls extend between the tire engaging and spoke-engaging portions. The rim includes at least one through-hole and a pattern of through-thickness stitching reinforcement at the through-hole. The tire-engaging and spoke-engaging portions and first and second sidewalls form a toroid.
Abstract:
The present invention relates to a method for producing a rim ring for a wheel rim, in particular for a wired-on wheel rim, with the following steps: providing an outer rim profile made of hardened composite fibrous material, providing a plastic shaping element, providing at least one top layer made of composite fibrous material, inserting the plastic shaping element radially within the outer rim profile, and positioning the top layer relative to the plastic shaping element and to the outer rim profile such that at least part of the top layer extends from the plastic shaping element onto the outside of the outer rim profile. The present invention further relates to a method for fastening spokes made of composite fibrous material to a rim ring. Finally, the present invention also relates to a rim ring, a wired-on wheel rim and a bicycle with wired-on wheel rims.
