Embodiment Construction

[0009] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0010] Such as figure 1 As shown, the normally-closed fixed butterfly spring caliper disc brake includes a brake disc 1 and friction plates 2 symmetrically arranged on both sides of the brake disc 1, a push plate 3 and a body oil cylinder 4, and the friction plates 3 are arranged On the friction plate 5, the friction plate 5, the push plate 3 and the piston 41 are fixedly connected, the piston 41 is set in the body oil cylinder 4, the end of the piston 41 is sleeved with a butterfly spring 6, and the friction plate 3 is set On the side of the brake disc 1, the friction plate 2 is closely attached to the brake disc 1 by the force of the butterfly spring 6, so that it is in a normally closed state, and oil is supplied to the body oil cylinder 4 through the oil supply port 7 to realize Open the brake.

[0011] The body oil cylinder 4 is provided with an ...

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...
