Fixed caliper disc brake with electromagnet

Abstract

The invention discloses a fixed caliper disc brake with an electromagnet. The fixed caliper disc brake comprises brake calipers and a brake disc, wherein the brake calipers stretch over the two sides of the brake disc, and are fixedly connected to an outer vehicle frame; by taking the brake disc as the center, the brake calipers are symmetrically provided with two piston cavities; armatures capable of moving back and forth along the piston cavities are arranged in the piston cavities; one side, facing towards the brake disc, of each armature is connected with a brake pad; the other sides of the armatures are provided with clamping slots; and magnet exciting coils are arranged in the clamping slots. The fixed caliper disc brake has the effects that: the armatures are arranged at the two sides of the brake disc, and the magnet exciting coils are arranged in the armatures, so that when the magnet exciting coils are electrified, the armatures become electromagnetic blocks with magnetism, and drive the brake pads to move towards the brake disc, thereby realizing braking. Compared with a mode that a conventional fixed caliper disc brake enables the brake pads to move towards the brake disc through a hydraulic pushing piston, the scheme adopts an electromagnetic system to replace a complex hydraulic system, and therefore, the fixed caliper disc brake provided by the scheme is simple in structure and is reliable in performance.

Description

technical field [0001] The invention relates to a fixed caliper disc brake, in particular to a fixed caliper disc brake with an electromagnet. Background technique [0002] The rotating element in the friction pair of the disc brake is a metal disc that works on the end face, called the brake disc. The friction elements clamp the brake disc from both sides to produce braking. There are many structural forms of the fixed element, and disc brakes can be generally divided into two types: caliper disc type and full disc type. [0003] Caliper disc brakes can be divided into fixed caliper disc type and floating caliper disc type according to the structure of the brake caliper. In the current fixed caliper disc brakes, in order to make the brake blocks on both sides of the brake disc can be Moving to the brake disc, it is necessary to set a brake fluid flow passage across the brake disc in the brake caliper. In this case, the fixed caliper disc brake needs to add an additional h...

[0003] Caliper disc brakes can be divided into fixed caliper disc type and floating caliper disc type according to the structure of the brake caliper. In the current fixed caliper disc brakes, in order to make the brake blocks on both sides of the brake disc can be Moving to the brake disc, it is necessary to set up a brake fluid flow passage across the brake disc in the brake caliper. In this case, the fixed caliper disc brake needs to add an additional hydraulic system, which will undoubtedly increase the complexity of the entire braking system.
