Abstract

The invention discloses an eddy current and friction brake device for vehicles. The eddy current and friction brake device comprises a brake disc, a brake caliper, a first annular sector eddy current retarder and a second annular sector eddy current retarder. The brake caliper holds the upper portion of the brake disc. The first annular sector eddy current retarder and the second annular sector eddy current retarder symmetrically hold two sides of the brake disc relative to the brake caliper. Each annular sector eddy current retarder is formed by two rows of electromagnets on two inner annular sector faces of an annular sector frame. The eddy current retarders and the friction brake are integrated according to the principle of advantage complementing, eddy current brake is used when the vehicle runs at high speed, and the brake caliper is used for friction brake when the vehicle runs at low speed. By the eddy current and friction brake device for vehicles, safety, economy, stability, comfort level and efficiency in vehicle braking are improved. The eddy current and friction brake device for vehicles is compact and simple in structure, convenient to mount and easy to maintain.

Description

technical field [0001] The invention relates to a vehicle braking device, in particular to an eddy current and friction integrated braking device applied to vehicles. Background technique [0002] As a vehicle auxiliary braking device, the eddy current retarder can significantly improve the safety, economy, environmental protection, stability and comfort of the vehicle, so it is more and more widely used. When the eddy current retarder is working, the electromagnetic coil is energized to generate a magnetic field, and the magnetic flux in the area surrounded by countless closed wires inside the working surface where the rotating rotor cuts the magnetic force line changes, thereby generating a vortex-shaped induced current on the rotor working surface. That is, the eddy current. According to the Lenz law in physics, the electromagnetic field produces resistance to the charged rotor to prevent the rotor from rotating, that is, the braking force. The kinetic energy is finally ...
