Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

The structure of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the disc brake axle provided by the embodiment of the invention comprises an axle body 1, two brake discs 2 are sleeved on the outer surface of the axle body 1, brake calipers 3 are respectively used by matching the outer surfaces of the two brake discs 2, wheel shafts 4 are respectively sleeved on the left side and the right side of the axle body 1, and the opposite ends of the two wheel shafts 4 are respectively used by matching with the left side and the right side of the brake discs 2.

Referring to fig. 1, 2 and 3, the right brake caliper 3 includes a double air chamber rear shell 301, the bottom of the double air chamber rear shell 301 is used in cooperation with the outer surface of the brake disc 2, an air chamber push rod 302 is used in cooperation with the right side of the double air chamber rear shell 301, a double air chamber middle shell 303 is used in cooperation with the left side of the double air chamber rear shell 301, a double air chamber front shell 304 is used in cooperation with the left side of the double air chamber middle shell 303, and an air chamber pull rod 305 is used in cooperation with the left side of the double air chamber front shell 304.
