Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example (b): the invention provides a technical scheme that: as shown in fig. 1-3, a fully sealed pneumatic wet brake includes a housing, a brake disc disposed in the housing, a friction plate disposed at one end of the brake disc, and a piston disposed at the other end of the brake disc; a hub is arranged in the friction plate, the hub penetrates through the front end cover to fix the friction plate in the shell, and a floating oil seal is arranged between the front end cover and the hub; the piston passes through the ring gear push disk control position of one end, the ring gear push disk meshes with the one end of gear shaft, the gear shaft passes rear end cap and leg joint, be equipped with seal structure between rear end cap and the gear shaft, air chamber drive adjustment arm rotates and drives the gear shaft and rotate, promotes the piston motion, piston, gear shaft and ring gear push disk are 45# steel or 40Cr, the material is wear-resisting, the rigidity is big, can satisfy the operation requirement.
Furthermore, the piston, the steel balls and the gear ring are in rigid connection, and the steel balls roll between the gear ring and the piston. The piston and the shell are limited by a clamping groove, the piston does not rotate along with the gear ring but can axially move back and forth, an oval ball track pit which spirally rises from deep to shallow is arranged between the piston and the gear ring, steel balls are arranged in the pit, and the steel balls can be driven to move from deep to shallow when the gear ring rotates, so that the piston is pushed to axially move, the piston pushes the brake pad to be clamped tightly, and the purpose of braking is achieved.
When a brake plate is stepped on by a foot, an air chamber device can be triggered, an adjusting arm gear is pushed by an air chamber push rod to enable a gear shaft to rotate, the other end of the gear shaft is a half gear, a gear ring is driven to rotate, a clamping groove is arranged between a piston and a shell, the piston does not rotate along with the gear ring but can axially move back and forth, an oval ball raceway pit which spirally rises from deep to shallow is arranged between the piston and the gear ring, steel balls are arranged in the pit, and the steel balls can be driven to move from deep to shallow when the gear ring rotates, so that the piston is pushed to axially move, the piston pushes a brake pad to clamp, and the purpose of braking is achieved.
Furthermore, a return spring is arranged between the piston and the shell, when the brake is released, the spring can enable the piston to move axially to return to the original position, and the brake pad is automatically dispersed under the action of centrifugal force, so that the purpose of releasing the brake is achieved.
Furthermore, an oil inlet and an oil outlet of the shell are used for circulating oil to disperse.
The brake disc heat dispersion of this structure is more excellent, has avoided causing the brake disc to last high temperature and then seriously influence the emergence of brake performance hidden danger because of lasting the brake.
