Normally-closed fixed belleville spring caliper disc brake

Abstract

The invention discloses a normally-closed fixed belleville spring caliper disc brake. The brake comprises a brake disc, friction sheets, push plates and machine body oil cylinders, wherein the friction sheets, the push plates and the machine body oil cylinders are symmetrically arranged on the two sides of the brake disc. The friction sheets are arranged on a friction plate, and the friction plate, the push plates and pistons are fixedly connected. The pistons are arranged in the machine body oil cylinders, and the tail ends of the pistons are sleeved with belleville springs. The friction sheets are arranged on the side face of the brake disc, the friction sheets can be tightly attached to the brake disc and act on the brake disc under the acting force of the belleville springs, and the brake is made in a closely-closed state; oil is supplied to the machine body oil cylinders through an oil supply port, so that opening brake is realized. According to the normally-closed fixed belleville spring caliper disc brake, the positions between the friction sheets and the brake disc are fixed, gaps can be adjusted conveniently, the friction sheets can be replaced conveniently, the size is small, the braking torque is large and the braking effect is good.

Description

technical field [0001] The invention relates to the field of brakes for dynamic tamping machines, in particular to a normally closed fixed butterfly spring caliper disc brake. Background technique [0002] A brake is a device that has the functions of decelerating, stopping or maintaining a stopped state of moving parts (or moving machinery). It is a mechanical part that stops or decelerates moving parts in the machine. composition. There is usually only one brake caliper on the existing disc brake, and the two oppositely arranged caliper bodies of the brake caliper are respectively connected to a pair of offset brake arms, and each brake arm is connected to the offset brake arm through a lever mechanism. Push mechanism transmission connection. When this kind of disc brake is braking, the brake caliper is clamped on the brake disc, and the inertial force on the brake disc acts on the brake arm through the brake caliper, so that the brake arm is subjected to a large force p...

AI Technical Summary

Problems solved by technology

When this kind of disc brake is braking, the brake caliper is clamped on the brake disc, and the inertial force on the brake disc acts on the brake arm through the brake caliper, so that the brake arm is subjected to a large force perpendicular to its swing direction. The torsion of the brake makes the overall force of the brake unbalanced, the braking torque is small, the structure is not compact, the shaft sleeve of the device on the brake arm is easily damaged, and the service life is reduced.
