Detailed Description

the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the illustrated electric spindle brake caliper braking structure includes an oil cylinder 1, a first piston 2, a second piston 3, and a brake disc 4, where the oil cylinder 1 is fixedly installed in the brake caliper, the oil cylinder 1 is of a concave structure, two oil inlets 5 are symmetrically formed in one side of the piston, two pistons 2 and two pistons 3 are symmetrically distributed in the oil cylinder 1, and the brake disc 4 is located at a concave opening of the oil cylinder 1, and oil is injected through the oil inlets 5 to generate oil pressure, so as to push the first piston 2 and the second piston 3 to press the brake disc 4 for friction braking.

The first oil port 6 and the second oil port 7 are symmetrically formed in two sides of the oil cylinder 1, the first piston 2 and the second piston 3 respectively penetrate through the first oil port 6 and the second oil port 7 in a sliding mode, and sealing plates 8 are fixed on the inner walls of the first oil port 6 and the second oil port 7 to play a role in sealing.

The specific implementation mode is as follows: when needs are braked to brake disc 4, through oiling in two oil inlets 5 of case hydro-cylinder 1 one side to produce the oil pressure, because connecting plate 9 outside and hydro-cylinder 1 inner wall sliding connection, so promote connecting plate 9 and remove, drive first piston 2 and second piston 3 and outwards remove in step, thereby realize compressing tightly brake disc 4 friction braking.

The first piston 2 and the second piston 3 are positioned at one end in the oil cylinder 1 and are fixedly provided with a connecting plate 9, and the outer side of the connecting plate 9 is in sliding connection with the inner wall of the oil cylinder 1, so that the first piston 2 and the second piston 3 synchronously advance and retreat.

The semi-metal brake pad 10 is fixedly sleeved on the outer sides of the ends, close to the brake disc 4, of the first piston 2 and the second piston 3, so that the friction force is increased, and the braking effect is better.
