Abstract

The invention discloses an electromagnetism and hydraulic pressure compound brake with the self power generation function and a working method. A hydraulic oil circuit is arranged in a braking support, and is connected with a left wheel cylinder piston and a right wheel cylinder piston, two compound brake disks are arranged between the left wheel cylinder piston and the right wheel cylinder piston, an electromagnetic coil is arranged between the two compound brake disks, and faces the electromagnetic braking surfaces of the compound brake disks, copper claddings are arranged on the electromagnetic braking surfaces respectively, each copper cladding is parallel to the cross section of the electromagnetic coil, an electromagnetic gap is reserved between each copper cladding and the cross section of the electromagnetic coil, the size of each electromagnetic gap ranges from 1mm to 2mm, a rotary shaft is fixedly connected with the centers of the compound brake disks, the rotary shaft, an automobile tire and a transmission shaft are connected together, permanent magnets are fixedly embedded into the rotary shaft, the magnetic poles of the permanent magnets are arranged in a staggered mode, a power generation stator coil is arranged outside the permanent magnets, the size of a gap formed between the power generation stator coil and each permanent magnet ranges from 1mm to 2mm, the rotary shaft and the compound brake disks rotate synchronously, the permanent magnets carry out power generation by cutting the magnetic field of the power generation stator coil, generated electric currents serve as field currents of the electromagnetic coil after being processed through rectification and voltage stabilization, and self energy supply is achieved.

Description

technical field [0001] The invention relates to a brake device of a passenger car, in particular to an electromagnetic-hydraulic composite brake with self-generating function. Background technique [0002] At present, the braking system of passenger cars is basically realized through friction braking through hydraulic power assist. Dynamic heat failure, wading failure, long braking response time, high maintenance cost, friction dust pollution and other problems. [0003] In order to overcome the shortcomings of the current hydraulic braking system, combining the hydraulic system with the non-contact electromagnetic braking system, using electromagnetic braking to divert the energy of the vehicle braking system is a direction for the development of the braking system. Due to friction braking and electromagnetic braking The principle of braking, the material of the brake disc, the clearance requirements between the brake disc and the friction block or the brake disc and the e...
