An external connection type constant lock hydraulic disc brake device

Abstract

The invention discloses an external connection type normal-locking hydraulic disc brake device. The device comprises a main clamp body, an external connecting frame, a mounting plate, jackscrews, guide screws, a piston and a spring; and the device is characterized in that a piston hole is formed in the bottom of the main clamp body, the piston is pressed in the piston hole in a matched mode, a spring guide hole is formed in the middle of the main clamp body, the spring is compressed in the spring guide hole, guide threaded holes are formed in the middles of the left side face and the right side face of the main clamp body respectively, guide groove holes are formed in the left side face and the right side face of the external connecting frame respectively, the front ends of the guide screws are installed in the guide threaded holes through threads, the rear ends of the guide screws are clamped in the guide groove holes, four threaded mounting holes are uniformly distributed in the rearend face of the external connecting frame, four guide unthreaded holes are uniformly distributed in the end face of the bottom of the main clamp body, the rear ends of the jackscrews are connected into the threaded mounting holes through threads, the front ends of the jackscrews are installed in the guide unthreaded holes, a supporting guide column is fixedly connected to the mounting plate through riveting, the supporting guide column is installed in a guide hole, and a pit is formed in the end face of the outer side of the piston.

Description

Technical field [0001] The invention relates to the technical field of hydraulic brakes, in particular to an external connection type constant-lock hydraulic disc brake device. Background technique [0002] With the improvement of people’s safety awareness, braking methods that rely on artificial active braking in an unlocked state under normal conditions can no longer meet people’s needs. Normally locked brakes that can only move through active unlocking under normal conditions are becoming more and more important, especially Shaky ships, large medical equipment, baby strollers, and mining cargo tools are particularly important. Some active brakes have great safety hazards due to human operation, such as universal wheels with brakes and brakes used on strollers. At present, all types of brakes on the market are always open brakes, especially when it comes to hydraulic disc brakes, they are all active brakes. Normally open hydraulic disc brakes have complex structure and unreaso...

AI Technical Summary

Problems solved by technology

Some active brakes have great potential safety hazards due to human operation, such as universal wheels with brakes and brakes used on baby carriages.

At present, all kinds of brakes on the market are normally open brakes, especially in the field of hydraulic disc brakes, which are active brakes. The structure of the normally open hydraulic disc brake device is complicated, and the design of the sealing groove is unreasonable, which is not conducive to processing. The pressure oil achieves the braking effect by pushing the piston to squeeze the friction plate. However, there is a great demand for normally closed brakes in daily work and life.

Some permanent lock brakes use rigid brakes, which have a large impact on the mechanical structure, especially when braking during exercise, and are very easy to damage, such as the use of stuck gears or truck wheels, affecting user experience
