摘要： An electro-hydraulic actuator for actuating a brake caliper may have an electric motor with a drive shaft, a transforming mechanism and a first housing to accommodate the transforming mechanism and support a second housing of the electric motor. The transforming mechanism may include a reduction gear to demultiply the rotary motion of the drive shaft. The reduction gear may have a crown with inner toothing in one piece and that is rotationally locked. The crown may have a front portion directly shape-coupled to and inserted in the second housing of the electric motor and a connection integral with the first housing of the transforming mechanism for a precise centering between the electric motor and the reduction gear with respect to the axis of the drive shaft and with respect to a central axis of the reduction gear.

摘要： An object of the present invention is to provide a sprocket that mitigates the impact of tension fluctuations resulting from load torque changes, suppresses noise and vibration, ensures stable chain behavior, prevents sprocket durability loss and the generation of harmonics during rotation, along with a chain drive system. Tooth roots between adjacent teeth of the sprocket include those with a radial deviation from a root circle of a standard tooth profile, set within a predetermined numerical range corresponding to a tooth pitch. A phase variation pattern is created by changing a root radius in accordance with an angular position. The phase variation pattern has a waveform with an amplitude varied within a range of (1/7)Amax, where Amax represents a maximum amplitude. The chain drive system includes a plurality of sprockets and a chain passed over the sprockets, at least one of them being the above-described sprocket.

摘要： A lightweight gear includes a hub, and a tooth ring defining a plurality of gear teeth. The tooth ring includes an inner core composed of a polymer-based material that is coupled to the lattice structure. The lightweight gear includes a lattice structure interconnecting the hub and the tooth ring. The lattice structure has a density that varies radially based on an operating condition of the lightweight gear and the lattice structure is composed of a metal or a metal alloy.
