Provided is a managed article that allows an engraved code to be excellently detected. An engraved code 11including a plurality of dot dented portions 15 is forced: on a managed article 10. The engraved code 11 includes. An opening peripheral edge portion 22 of each of the dot dented portions 15 has a quadrilateral shape. This configuration leads to detection of the dot dented portion as a quadrilateral dot. Therefore, this configuration allows the engraved code to be excellently detected.

The present disclosure provides systems for mitigating brake vibration. In various embodiments, a brake force distribution arrangement may comprise: a member in operable communication with an actuator having at least two contact surfaces such that as one of the at least two contact surfaces moves in a direction of actuation of the actuator the other moves in a direction opposite to the direction of actuation of the actuator.

A force transmitting assembly includes a mounting flange having a central opening to receive a shaft, wherein the mounting flange is mountable on a frame, a rotor disc mountable on the shaft and rotatable with the shaft, the rotor disc having a first planar face and a second planar face, a float plate having a first friction surface engageable with the first planar face, and a pressure plate having a second friction surface engageable with the second planar face. The brake assembly also includes a spring housing, which operates as a piston, and a cylinder coupled to the spring housing to form a fluid pressure chamber, wherein the spring housing moves in a first direction when pressurized fluid enters the fluid pressure chamber and the spring housing moves in a second direction when pressurized fluid exits the fluid pressure chamber. The assembly further includes a plurality of nested tube subassemblies supporting the float plate, the pressure plate, and the spring housing to allow axial movement of at least one of the float plate, the pressure plate, and the spring housing. The nested tube subassemblies also transmit torque from the rotor to the mounting flange during the engaged condition of the brake assembly.

A piston housing manufactured by an additive manufacturing process is provided. The piston housing may comprise a plurality of chambers. The chambers may be in fluid communication with one another via non-linear fluid passageways. The non-linear fluid passageways may be defined in structural members configured to stiffen the piston housing.

A brake caliper arranged straddling a braking band of a brake disc has first braking surface and second braking surface and a caliper body having a first caliper body portion facing the first braking surface, a second caliper body portion facing the second braking surface, and a bridge connecting the first and second caliper body portions. An outer caliper body surface faces away from the braking band. At least one of the first and second caliper body portions accommodates a thrust element. A light lamella protruding from the outer caliper body surface has a plate having two opposite plate surfaces, and plate edges. The plate has a predefined plate thickness and a side edge directed at the caliper body. The light lamella has a lighting body having a light source and transmitting, when activated, light radiation into the plate thickness so that the light radiation is distributed by the two opposite plate surfaces and/or the plate edges.

An electric vehicle with at least one brake system and an axle and a method to operate the electric vehicle. The at least one brake system is arranged at the axle and includes a wet service brake, a parking brake, and an actuator. The actuator is adjustable and can communicate with a service brake in a service brake region or with the parking brake in a securing region to generate a braking action at the axle in each instance. A neutral region in which the actuator communicates neither with the service brake nor with the parking brake is located between the service brake region and the securing region. A plurality of brake systems are advantageously used jointly in the various configurations.

A land vehicle includes a frame structure, a plurality of wheels supported by the frame structure, and a body supported by the frame structure. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The body includes a first sidewall arranged on one side of the vehicle and a second sidewall arranged on another side of the vehicle opposite the first sidewall.

The present invention includes an aircraft drive system comprising a main rotor gearbox comprising a first and a second input; a first drive system comprising a first engine reduction gearbox connecting a first engine to the first input of the main rotor gearbox at a reduced shaft speed; and a second drive system independent from and redundant with the first drive system, the second drive system comprising a second engine reduction gearbox connecting a second engine to the second input of the main rotor gearbox at the reduced shaft speed.

The electric brake device includes an electric motor, a friction member operator, a friction member, a brake rotor, and a control device. A braking force estimator provided in the control device includes: a direct estimator configured to convert output of a braking force sensor which detects a load or displacement corresponding amount, to a braking force; and an indirect estimator configured to estimate the braking force on the basis of information other than output of the braking force sensor. A range in which the braking force is estimated by the direct estimator is a specified low-braking-force range, and in a range beyond this range, estimation of the braking force is performed by the indirect estimator.
