A lock ring spreader is capable of being mounted to a lock ring having a first end and a second end. The lock ring spreader comprises a first mount that is mountable to the lock ring near the first end of the lock ring and a second mount that is mountable to the lock ring near the second end of the lock ring. A crank arm is pivotally coupled to the first mount and extends radially outward from the first mount relative to the lock ring. A link arm is pivotally coupled to the second mount and the crank arm, and extends radially outward from the second mount relative to the lock ring. Pivoting the crank arm radially inward relative to the lock ring pivots the link arm relative to the crank arm and expands the distance between the first mount and the second mount.

A device for masking securing boreholes in rims with masking elements having a storage container for the masking elements, a pressure generation unit, a connection unit connected to the storage container and an at least substantially tubular discharge device, which is secured at one end to the connection unit and which has a discharge opening at the opposite end for discharging the masking elements. The discharge device has a tube wall in which a channel for conducting a fluid is formed, the channel being connected to the pressure generation unit. The tube wall consists at least partially of an elastic material, through which the channel runs or in which a cavity connected to the channel is formed, such that, when the pressure of the fluid is changed, the tube wall deforms and releases the clamping on the masking elements. The connection unit and the discharge device are formed preferably as one piece in a 3D printing method.

The present invention relates to torque application tools, such as an electronic torque screwdriver, with a multiple axis gyroscope (such as a 3-axis gyroscope or other type of gyroscope) and torque sensor that allows for simultaneous or sequential measurement of torque and angle around the axis of the tool. Targets for torque and angle measurements may be used to create algorithms to detect breakaway torque, residual torque, or to perform error proofing to ensure unique fasteners are tightened.

A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.

A bicycle real wheel hub includes pulling spokes and static spokes connected to the disks thereof. The hub includes a tubular portion with two disks respectively connected to two ends of the tubular portion. Multiple protrusions protrude from the inner side of each disk. The head of each pulling spoke is secured to the protrusion corresponding thereto. The head of each static spoke is secured to the disks. The heads of the pulling spokes are located closer to the middle point of the tubular portion than the heads of the static spokes. When the hub rotates, the static spokes provide strength in the axial direction of the hub, and the pulling spokes have strong tension so that the hub bears higher torque.

Aerodynamic wheel covers may include a hub assembly coupled with a hub of a large vehicle, such as a truck. A base assembly may be coupled to the hub assembly, and a disk assembly may be coupled with the base assembly such that removal and installation of the disk assembly may be accomplished without tools.

A method for producing a product including a composite fiber part and a second part, wherein the second part includes a carrier part, wherein the carrier part is a replica of a press tool configured to be heated and to apply a pressure, the method including applying, in a non-cured state, the composite fiber part on the carrier part, arranging the carrier part including the composite fiber part on the press tool, curing the composite fiber part on the carrier part, and removing the product from the press tool, wherein after removal from the press tool the composite fiber part and the carrier part constitutes together at least a part of the finished product. Also disclosed is a composite fiber product including a composite fiber part and a second part.

An axle assembly, including: an axle sleeve with first and second end faces, an opening, and a first engagement surface; a control shaft with an engagement end, a control end, and a second engagement surface. The control shaft overlaps the opening and is axially displaceable in extending and retracting directions. The control shaft is rotatable relative to the axle sleeve between: (i) a first orientation where the control shaft is retained to the axle sleeve by an overlie engagement between the first and second engagement surfaces to restrict the axial displacement of the control shaft in the retracting direction at a first axial position; and (ii) a second orientation circumferentially offset from the first orientation such that the first and second engagement surfaces are not overlying and the control shaft may be axially displaced in the retracting direction relative to the first axial position.

The invention relates to a single wheel caster with a support element including a top element and a base element which includes at least one support arm, wherein the base element receives at least one hub for a wheel, wherein a thread protector is arranged on the hub, wherein a fixation device is arranged between the wheel and the support element. It is an object of the invention to provide a novel single wheel caster with substantially reduced assembly complexity. The object is achieved in that the locking device is arranged without additional fastening elements in an interior of the support element between at least one inner surface of the support element and at least on contact surface arranged rotationally fixated at the wheel, wherein the contact surface firmly contacts the locking device when the caster is assembled.

Aerodynamic wheel covers may include a hub assembly coupled with a hub of a large vehicle, such as a truck. A base assembly may be coupled to the hub assembly, and a disk assembly may be coupled with the base assembly such that removal and installation of the disk assembly may be accomplished without tools.
