An axle assembly having a unitary trunnion bracket, an axle, and a support bracket. The unitary trunnion bracket may include an axle interface portion and a bracket interface portion. The bracket interface portion may extend from the axle interface portion. The axle may engage the axle interface portion. The support bracket may engage the bracket interface portion.

There is provided a configuration that can precisely detect abrasion of brake shoes of a railway vehicle. A brake shoe abrasion detection unit includes: at least one abrasion detection RF tag that is attached at a position of an abrasion limit of a brake shoe of a railway vehicle tread brake or a position closer to a braking surface than the abrasion limit; and a reference RF tag that is attached at a position beyond the abrasion limit of the brake shoe.

An electric brake system that appropriately brakes a rotary body of a human powered vehicle in various situations is applicable to a human powered vehicle and includes a brake device including an electric actuator operated by electric power from a power supply, and a braking portion driven by the electric actuator to brake a rotary body of the human powered vehicle, a state detector detecting a state of the human powered vehicle other than an operation of the brake device performed by a user, and a control unit controlling the brake device so that the braking portion brakes the rotary body based on a detection result of the state detector.

A truck mounted braking system is provided with a mechanical pivot adjustment on the bake lever connected to the brake cylinder push rod to permit the braking force applied to the wheels to vary depending on the lading condition of the car, without involving additional pneumatic elements such as a pneumatic empty load device. The brake cylinder may be provided with a channel which permits the push rod to achieve different positions based on different positions of the brake cylinder push rod.

A railcar steering bogie includes a bogie frame, a wheelset, an axle box suspension, a steering mechanism configured to steer the wheelset, a brake unit, and a brake unit support link. The brake unit includes: a main body frame; a brake shoe supported by the main body frame and pressed against a wheel tread of the wheel during braking. The brake unit support link couples the axle box suspension and the brake unit and transmits displacement of the axle box in a car longitudinal direction to the brake unit at least during steering performed by the steering mechanism. The brake unit support link restricts the brake unit from being displaced outward in a car width direction by a predetermined distance or more during the braking. At least one of a side surface of the brake unit support link and a side surface of the brake unit includes a sliding surface.

Methods and systems are provided for an automatic, electric hub lock with a manual override capability. In one example, the electric hub lock may be actuated responsive to one or more of a manipulation of a manual dial proximate a vehicle wheel and an electronic control inside a passenger compartment. In another example, a method includes overriding the automatic control of the hub lock responsive to manual request for operating the vehicle in four-wheel drive mode.

A pedal travel simulator for a hydraulic vehicle power braking system with a cup-shaped cylinder cover in which a piston spring is accommodated, which is held by an orifice disk as a stop for a piston of the pedal travel simulator in the cylinder cover. Recesses are provided in an outer edge of the orifice disk, through which the piston is able to displace brake fluid on its rear side out of a cylinder of the pedal travel simulator through a circumferential groove into a return.

A vehicle includes a rotationally movable actuating element and a sensor arrangement for measuring an actuating angle of the actuating element. The sensor arrangement has a measuring acceleration sensor which is fastened to the actuating element, and a reference acceleration sensor which is fastened immovably to the vehicle. A method for measuring the actuating angle of a rotationally movable actuating element in a vehicle, a measuring arrangement configured to carry out a method for measuring, a computer program product and a provision apparatus for the computer program product, are also provided.
