DirectFlux™ Direct-Flux Power Management Product Series

Product overview

Power management product series based on JJE's patented DirectFlux™ direct-flux electromagnetic clutch technology, building a dual system of single functions plus combined functions to provide vehicle manufacturers with a one-stop high-medium-low power management solution. Single functions: disconnect differential (free switching between 4x4 and 4x2 drive modes), direct-flux mechanical differential lock (eLocker, improving climbing, cross-axle and self-recovery performance), mechanical limited-slip differential (LSD, requiring no driver intervention, instantaneous response, improving handling stability and moderate off-road capability). Combined functions: DL Combo lock-disconnect integrated differential (integrating differential + differential lock + disconnect, the world's first), LL Combo lock-limited-slip integrated differential (combining limited-slip differential + differential lock). All combined-function products use common dimensions and mechanical interfaces, so vehicle manufacturers do not need to change the powertrain layout, mounts or half-shaft design.

Key specifications

Core advantages of the direct-flux technology: response speed 50-70ms; high torque density; monostable or bistable functions can be achieved; no holding current required, more efficient; package dimensions and mechanical interfaces remain consistent with conventional open differentials or single-function products. The electromagnetic clutch products are applicable to two major fields: hybrid mode management and multi-speed transmission shift control. The lock-disconnect integrated differential can reduce cost by about one third; the 300kW four-in-one electric drive system (with integrated direct-flux mechanical differential lock) has a system output torque exceeding 6000N·m.

Applications
  • Off-road vehicles (hard off-road: climbing, cross-axle, self-recovery)
  • Handling stability improvement and moderate off-road
  • Complex surfaces such as ice and snow, wet and slippery, gravel
  • Switching between 4x4 and 4x2 drive modes
  • Hybrid mode management
  • Multi-speed transmission shift control
  • Off-road models such as BAIC BJ60e and BJ40e (300kW four-in-one electric drive system)
