The synchronizer systems of heavy-duty transmissions work by applying torque with high loads, frequent cycle shifting and thermal shifts. They are designed to equalize the speed of rotating parts prior to engagement, which minimizes shift shock and tooth wear. The cone ring, and more specifically the synchronizer
Sintered silicon nitride (SSN) is a high-performance structural ceramic material. It has a low density and a significantly high level of thermal-shock resistance, wear resistance, and good fracture toughness. As a result, components manufactured with SSN support reliable performance in environments including rapid temperature cycling,
Powder metallurgy (PM) is commonly used to manufacture key components of electric motors, including traction motor parts, because it helps engineers achieve the efficiency and tight tolerances required in EV applications. By adjusting alloy composition and controlling powder characteristics, PM enables the desired mechanical strength
Pressureless sintering is a sintering process in which powder material is converted into dense components without applying external pressure during sintering. The process depends solely on controlled heating to promote atomic diffusion and bonding between particles. It is used for producing components where uniform microstructure,
A synchronizer sleeve, also known as a sliding sleeve, is a precision-engineered axial coupling component within a manual transmission synchronizer assembly. Synchronization sleeve works with the synchronizer hub and baulk (or blocker) ring to match the rotational speeds of the shaft and the selected gear
Solid state sintering is a heat treatment process in which loose powder is converted into solid coherent components. The process is conducted at elevated temperatures, typically between 70% and 90% of the material’s melting point. This heating leads to the formation of chemical bonds between
Metal injection molding (MIM) and metal 3D printing are advanced production technologies that have brought about a rapid shift in modern manufacturing. Metal injection molding can create small and intricate components as tiny as 2 mm in diameter, while weighing less than 1 g without
Sintered gears, also referred to as powder metal gears, are manufactured by the powder metallurgy (PM) process. They have near-net-shape geometry and precise tooth profiles, which are important for efficient torque transmission in mechanical systems. Sintered gears are produced using iron-based alloys and other nickel
A crankshaft pulley is mounted on the end of the crankshaft and drives the engine’s accessory systems through a serpentine or V-belt. Most pulleys are built with a harmonic damper to absorb torsional vibration. The design usually includes an inner hub fixed to the crankshaft,
