Product Overview
The Automotive Shift Fork is a mechanical actuator within a transmission shifting mechanism. It moves a synchronizer sleeve or designated shifting element into position, allowing the transmission to engage the selected gear or operating mode. The fork's geometry, contact surfaces, and dimensional accuracy are important to the movement of connected parts and the consistency of gear selection.
During service, shift forks may experience repeated contact, friction, vibration, and cyclic mechanical loads. Material selection, casting quality, heat treatment, and machining therefore need to match the transmission design and its operating requirements.
Sangroove (Jiangsu) Machinery Co., Ltd. manufactures shift fork castings for transmission-related applications, with production processes that can include tooling development, casting, heat treatment, CNC machining, and surface protection. Listed material options include QT450-10, QT500-7, and QT600-3 ductile iron, with cast steel and alloy steel available for evaluation according to the component specification.
For OEM and Tier 1 projects, we support drawing-based manufacturing and agreed inspection requirements. Critical dimensions and functional interfaces can be defined according to the gearbox design, assembly conditions, and required production volume.
