An automatic transmission is provided, which includes a brake including a fixed-side cylindrical member spline-coupled to a transmission case, a rotation-side cylindrical member coupled to a given rotating member, a plurality of friction plates disposed between the fixed-side cylindrical member and the rotation-side cylindrical member, and including a fixed-side friction plate configured to be spline-engaged with the fixed-side cylindrical member and a rotation-side friction plate configured to be spline-engaged with the rotation-side cylindrical member, and a piston configured to engage the plurality of friction plates. The automatic transmission includes a shock absorbing member disposed between a spline part of the transmission case and a spline part of the fixed-side cylindrical member and configured to absorb impact when the fixed-side cylindrical member rotates relative to the transmission case.

A bush-type transmission mount, in which an orifice, operating as a fluid passage that connects a first fluid chamber and a second fluid chamber to each other, is directly formed to a desired length in a core that is coupled to a main rubber to improve vibration-damping characteristics. A membrane is fitted into an outlet portion of the orifice, which communicates with the first fluid chamber, in a sliding manner, thereby improving low-frequency idle vibration and high-frequency dynamic characteristics.

Embodiments of the invention are shown in the figures, where a method for manufacturing a gearbox, the method comprising: providing a predefined interval around an integer; providing a gearbox setup; determining a speed ratio of at least two components of the gearbox setup; comparing the speed ratio with the predefined interval around the integer; and manufacturing a gearbox in accordance with the gearbox setup in dependence on the comparison.

Integration of drive elements with an unsprung structure is disclosed. In one aspect of the disclosure, a motor includes a stator configured to mount to an unsprung structure of a wheeled vehicle through at least a damper or a spring. The motor further includes a rotor configured to drive a wheel of the vehicle.

A decoupling ring suitable for a planetary gear is disclosed. A decoupling ring includes an annular elastomeric base body and elastomeric formations. In embodiments, the elastomeric formations are uniformly spaced apart from one another, project in the radial direction from the base body, and run parallel to a central longitudinal axis passing centrally through the decoupling ring. With embodiments of the decoupling ring it is possible for the decoupling ring to be arranged on the circumferential side of a ring gear of a planetary gear.

Disclosed is a folding mechanism for an outside rearview mirror of a vehicle. In more detail, disclosed is an actuator mechanism of an outside rearview mirror for a vehicle. Here, the actuator mechanism includes a lower case including a shaft fixing region, a driving motor including a gear-shaft having one end engaged with the shaft fixing region and restricted in movement in a first axial direction and a body portion vibrating in the first axial direction, an actuator module; and an upper case including a first elastic support region and configured to cover the lower case. Here, the first elastic region elastically restricts vibration of the body portion in an axial direction.

An improved, low porosity, solid electrolyte membrane and a method of manufacturing the solid electrolyte membrane are provided. The low porosity, solid electrolyte membrane significantly improves both mechanical strength and porosity of the membrane, inhibits the growth of lithium dendrites (Li dendrites), and thereby maintains and maximizes electrochemical stability of an all-solid-state battery. This is accomplished by wet-coating a sulfide or oxide solid electrolyte particle with a thermoplastic resin, or a mixture of the thermoplastic resin and a thermosetting resin, using a solvent to prepare a composite and hot-pressing the composite at a relatively low temperature and at a low pressure.
