Abstract: A design scheme of the vehicle magnetic particle clutch
with permanent magnets (PM-MPC) is proposed based on the principle of two
magnetic fields superposition generated by both of the permanent magnets and
the exciting coils. According to the working characteristics of the clutch,
working process of the vehicle PM-MPC is analyzed, and the design objectives
of the clutch torque are proposed to meet the requirement of vehicle
operation under different loads. Based on a domestic economical passenger
vehicle as the matching type, the structure parameters of the permanent
magnet which can satisfy the design requirement are determined, and the
torque performance of the PM-MPC is gained by electromagnetic field
computation. Furthermore, it compares and analyzes the torque transmission
performance as well as the energy consumption characteristics of the PM-MPC
and the electromagnetic magnetic particle clutch (EM-MPC) with the same
structural size. Then, the results show that the vehicle PM-MPC in this
paper has the advantages of high torque transmission and low energy
consumption. Finally, the prototype of PM-MPC is produced which performance
is tested. More importantly, the correctness of the design and calculation
is verified as expected.
