摘要:
The bag roller in a fixed position serves as a transport device for supporting and moving material having uneven and/or fragile surfaces and, in a specific embodiment, is mounted in a support for use as a transportation element in a conveyer system, or as a forceful puller for lineal objects, such as pipelines, accommodating uneven dimensions.

An off road vehicle of the kind having fluid-distensible bag rollers for supporting the vehicle load uses bag rollers which are constructed to afford maximum flexibility in both the walls and tread and which are also constructed to be dynamically balanced.The vehicle also incorporates suspensions which effectively dampen oscillation of the bag rollers to facilitate and to permit high speed operations of the vehicle across rough terrain.A top drive roller is associated with a bag roller in certain embodiments of the off road vehicle in ways which minimize bag wear.Specific bag constructions are provided for improved operation of the off road vehicle for on-highway use.The vehicle includes two frame sections which are connected to permit frame (yaw) steering and swiveling (roll) between the two sections while preventing a bending between the frame sections (pitch) to thereby provide a strong back mode of operation. When equipped with 4 bags on each frame, the vehicle permits increased speed over rough terrain.The bag roller in a fixed position serves as a transport device for supporting and moving material having uneven and/or fragile surfaces and, in a specific embodiment, is mounted in a support for use as a transportation element in a conveyor system, or as a forceful puller for lineal objects, such as pipelines, accommodating uneven dimensions.

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.

The invention relates to a wheel for a motor vehicle, comprising a wheel body (3) with a rim tape (7) for receiving a tire and a rim star (9) or a wheel disk, through-holes (13) for receiving fastening means (17) of the wheel body (3) on a vehicle axle being formed in the rim star or in the wheel disk. The wheel body (3) is produced from a reinforced polymer material and is connected non-positively, positively or integrally to a cap (5), the cap (5) covering the rim star (9) or the wheel disk. Furthermore, the invention also relates to a process for producing the wheel.

The invention relates to a wheel rim having a wheel disk (3) made of a fiber composite and having fastener for fastening the wheel disk (3) to a wheel hub (5) of a vehicle, wherein the wheel disk (3) has at least one opening (8) for receiving the wheel hub (5) and the opening (8) is designed to have a conical centring surface (9) for the corresponding seat of a fastener. According to the invention the reinforcing fibers of the fiber composite are arranged in planar layers (10) and at least a part of the fiber layers (10) is arranged in an edge region (12) of the opening (8) perpendicular to the centring surface (9) of the wheel disk (3).
摘要:
The present invention applies to a molding method for a fiber-reinforced plastic structure having an internal cavity. Firstly, grain groups, which mainly consist of a plurality of high-rigidity grains, are accommodated in bags, and a plurality of cores are formed. A reinforcing fiber substrate, is placed between the plurality of adjacent cores so as to be interposed therebetween. For example, a plurality of molding base materials are prepared by surrounding each core with a prepreg, and the plurality of molding base materials are combined and placed inside a molding die, and the molding base materials are compression molded. When compression molding, a part of the outer surface of the cores is locally pressurized, and the internal pressure of the cores is increased, changing the shape thereof, thus eliminating voids that are present between the cores and the prepreg and/or the prepreg and the molding surface of the die.
