Problems solved by technology

[0002] Existing braking devices for motor vehicles and many equipment use the hydraulic system to drive the frictional resistance between the brake pads and the brake discs to brake. Because the oil pipes and seals of the hydraulic system are prone to aging, and the oil pressure joints are easy to loosen, etc., resulting in The hydraulic system is prone to failures such as oil leakage, which is not conducive to the safety of the brakes. At the same time, the widespread use of hydraulic oil is not conducive to environmental protection.

Abstract

A magnetofluid disc brake comprises a magnetofluid brake drive mechanism and brake units, and the magnetofluid brake drive mechanism comprises brake cylinders, magnetofluids, floating parts, elastic elements, electromagnetic coils and a controller. A brake pedal and a brake switch are utilized to transmit a brake signal to the controller, the controller and the electromagnetic coils are utilized to control the magnetic fields of the magnetofluids in the brake cylinders, the change of the magnetic fields of the magnetofluids is utilized to control the floatage of the floating parts in the magnetofluids, the floatage of the floating parts is utilized to drive pistons and piston rods to move, the piston rods are utilized to drive brake bases and brake pads to be in frictional contact with a brake disc for braking, and thereby the purpose of utilizing the controller to control braking is implemented.

Description

technical field [0001] The invention relates to a braking device, in particular to a magnetic fluid disc brake. Background technique [0002] Existing braking devices for motor vehicles and many equipment use the hydraulic system to drive the frictional resistance between the brake pads and the brake discs to brake. Because the oil pipes and seals of the hydraulic system are prone to aging, and the oil pressure joints are easy to loosen, etc., resulting in The hydraulic system is prone to failures such as oil leakage, which is not conducive to the safety of the brakes. At the same time, the widespread use of hydraulic oil is not conducive to environmental protection. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a magnetic fluid disc brake, which uses the specific gravity of the magnetic fluid in the controller, and uses the buoyancy of the floating part in the magnetic fluid to drive th...
