Document Type and Number:
WIPO Patent Application WO/2017/124371
Kind Code:
A1
Abstract:
A differential locking system (600) in inboard wet brake axles (112, 113) is provided. The differential locking system (600) includes: a first locking member (610) fixedly installed at a differential casing (310); a second locking member (620) spline-connected to a drive shaft; a cylinder housing (630) fixed to an axle housing (200) and having a hydraulic port (631) formed at one side of an inner wall thereof; a piston (640) installed in an inner space of the cylinder housing (630) to be elastically supported by a return spring (650); and a connecting bar (660) connecting the piston (640) and the second locking member (620) so that the second locking member (620) is moved by being linked with movement of the piston (640). The differential locking system (600) can be installed in inboard wet brake axles (112, 113) with very small inner spaces and can also enable construction vehicles to smoothly and efficiently operate in areas that are very slippery.
