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
The present invention relates to dynamic compaction machinery brake field, specifically a kind of normally closed fixing butterfly spring caliper disc brake.
Background technique
Break has the device making moving element (or movable machinery) deceleration, stop or keeping the functions such as halted state, and be the mechanical parts making the movement parts in machinery stop or slowing down, break is primarily of compositions such as support body, brake component and Effectors.Existing disk type braker is only provided with a brake calipers usually, and the caliper that two of this brake calipers is oppositely arranged is connected on a pair biased brake arm, and each brake arm is in transmission connection by leverage and biased pushing mechanism.This disk type braker is when braking, brake calipers clamping on the disc brake rotor, inertial force on brake disc is acted on brake arm by brake calipers and makes brake arm be subject to the larger torsion vertical with its swaying direction, make the entirety of break by force unbalance, braking moment is less, the axle sleeve of device on not compact, the easy damage brake arm of structure, and working life reduces.
Summary of the invention
For solving the technical problem of above-mentioned existence, the invention provides a kind of normally closed fixing butterfly spring caliper disc brake, between friction plate and brake disc, position is fixed, adjusting play is more convenient, and more renewal of facing renewal is also convenient, and volume is little, braking moment is large, good braking effect.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of normally closed fixing butterfly spring caliper disc brake, comprise brake disc and be symmetricly set in the friction plate of brake disc both sides, push pedal and body oil cylinder respectively, described friction plate is arranged on friction plate, described friction plate, push pedal are fixedly connected with piston, described piston is arranged in body oil cylinder, the sheathed butterfly spring of described piston end, described friction plate is arranged on the side of brake disc, by the active force of butterfly spring, friction plate is close to and acts on brake disc, it is made to be in normally off, by fuel feeding hydraulic fluid port to body oil cylinder fuel feeding, realize opening braking.
Be provided with spacer in described body oil cylinder, described spacer contacts with butterfly spring, and described body oil cylinder outer installment adjustment screw, acts on spacer by adjustment screw, the active force of adjustment butterfly spring.
The present invention devises the break being realized braking by hydraulic control friction plate, push pedal, friction plate and friction plate are fixed as one, friction plate is made to be in stationary state, conveniently can adjust the gap between friction plate and brake disc, be convenient for changing friction plate, decrease dead time, improve working efficiency, butterfly spring its own resilient is large, the strength of spring can also be adjusted by other adjustment modes, when making to be in normally off, braking moment is larger, braking effect is better, volume is little, be easy for installation and maintenance, long service life, be applicable to the braking of various machinery, moment braking when being particularly useful for the free off the hook of dynamic compaction machinery and crawl are transferred.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Describe the present invention below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, this normally closed fixing butterfly spring caliper disc brake, comprise brake disc 1 and be symmetricly set in the friction plate 2 of brake disc 1 both sides respectively, push pedal 3 and body oil cylinder 4, described friction plate 3 is arranged on friction plate 5, described friction plate 5, push pedal 3 is fixedly connected with piston 41, described piston 41 is arranged in body oil cylinder 4, the sheathed butterfly spring 6 of described piston 41 end, described friction plate 3 is arranged on the side of brake disc 1, by the active force of butterfly spring 6, friction plate 2 is close to and acts on brake disc 1, it is made to be in normally off, by fuel feeding hydraulic fluid port 7 to body oil cylinder 4 fuel feeding, braking is opened in realization.
Be provided with spacer 8 in described body oil cylinder 4, described spacer 8 contacts with butterfly spring 6, and described body oil cylinder 4 outer installment adjustment screw 9, acts on spacer 8 by adjustment screw 9, the active force of adjustment butterfly spring 6.
The present invention in use, after Installation and Debugging are good, when oil feeding line is not by fuel feeding hydraulic fluid port 7 fuel feeding, butterfly spring 6 passes through piston 41, push pedal 3, friction plate 5 by strength transmission to friction plate 2, friction plate 2 acts on brake disc 1, makes controller be in normally off; When oil feeding line is by fuel feeding hydraulic fluid port 7 fuel feeding, piston 41 drives push pedal 3, friction plate 5 and friction plate 2 to be separated from brake disc 1, compression butterfly spring 6, realizes opening braking.
Certainly; above-mentioned explanation is not limitation of the present invention; the present invention is also not limited in above-mentioned citing, and the change that those skilled in the art make in the essential scope of type of the present invention, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
