Disk type braking device with grading braking function

Abstract

The invention discloses a disk type braking device with a grading braking function. The disk type braking device with the grading braking function comprises a braking disk; one side of the braking disk is provided with a first braking head used for generating braking torque for the braking disk; the other side of the braking disk is provided with a second braking head used for generating braking torque for the braking disk, and the second braking head and the first braking head are of the same structure and are opposite in position; the second braking head and the first braking head each comprise a base frame, a first brake head and a second brake head, and the first brake heads and the second brake heads are arranged on the base frames, wherein the first brake head of the first braking head and the first brake head of the second braking head are symmetrical to each other, and the second brake head of the first braking head and the second brake head of the second braking head are symmetrical to each other; and the disk type braking device further comprises a force applying mechanism driving the first braking head and the second braking head to act, the force applying mechanism drives the first braking head or the second braking head to act so as to achieve trapezoidal grading braking on loads, the force applying mechanism drives the first braking head and the second braking head to act at the same time so as to achieve trapezoidal grading braking on the loads, and the force applying mechanism does not drive the first braking head or the second braking head to act so as achieve trapezoidal grading braking on the loads. The structure of the two braking heads is adopted for the disk type braking device, and trapezoidal grading braking on the loads can be achieved.

Description

technical field [0001] The invention relates to a disc brake device, in particular to a disc brake device with a graded braking function. Background technique [0002] Hydraulic disc brakes are usually composed of a friction pair, a force device and a brake release device. The friction pair is composed of a brake disc and a friction disc. The working surface is the two sides of the friction disc. The force device usually uses a special disc spring. Hydraulic disc brakes used in industrial sites often rely on hydraulic pressure to release the brake and spring force to lock the brake to achieve braking conditions. [0003] An electrohydraulic disc brake is disclosed in the prior art, which includes a base, a brake spring group, a brake shoe group, a left brake arm group, a right brake arm group and a pull rod, and an electrohydraulic pusher is fixed on the base. The push rod of the electrohydraulic pusher is connected to the horizontal axis of the spring group, the lower ends...

Problems solved by technology

This structure adopts the crankshaft structure to realize the release of the brake. Although it can obtain a large braking torque, it cannot realize the trapezoidal step-by-step braking of the load, nor can it realize deceleration braking.
