Hinge type brake executing mechanism based on double-shaft-extension motor and using method of hinge type brake executing mechanism

Abstract

The invention discloses a hinge type brake actuating mechanism based on a double-shaft-extension motor and a using method thereof, and relates to the field of hinge type brake actuating mechanisms. The hinge type brake actuating mechanism comprises a brake drum, the double-shaft-extension motor is arranged in the middle of the interior of the brake drum, and the upper end and the lower end of the double-shaft-extension motor are in transmission connection with a second motor shaft extension and a first motor shaft extension correspondingly; according to the device, the conversion path of energy needed by vehicle braking is shortened, the energy conversion frequency is reduced, and the system efficiency and capacity conversion path is improved: electric energy is converted into mechanical energy, the device is adjusted according to the length of a hinge sliding block mechanism, and when a brake pedal is small in opening degree, a first connecting rod acts preferentially to drive a first brake shoe to make contact with a brake drum and brake, and during emergency braking, a second connecting rod acts preferentially; the brake pedal is large in opening degree, the double-shaft-extension motor rotates rapidly, the first connecting rod and the second connecting rod are accelerated in progress, the first brake shoe makes contact with the brake drum firstly, the second brake shoe makes action contact then, the contact area is increased, friction force is increased, and rapid braking and reliable braking are achieved.

Description

technical field [0001] The invention relates to the field of hinged brake actuators, in particular to a hinged brake actuator based on a double-shaft extension motor and a method of using the same. Background technique [0002] A brake is a device with functions such as decelerating, stopping, or maintaining a stopped state of moving parts (or moving machinery). It is a mechanical part that stops or decelerates the moving parts in the machine. Commonly known as brakes, brakes. The brake is mainly composed of a frame, a braking part and a control device. Some brakes are also equipped with automatic adjustment devices for brake clearance. In order to reduce the braking torque and structure size, the brake is usually installed on the high-speed shaft of the equipment, but large equipment with high safety requirements (such as mine hoists, elevators, etc.) should be installed on the low-speed shaft close to the working part of the equipment superior. [0003] In the prior a...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the actuator of the brake often directly decelerates the moving parts quantitatively, which is inconvenient to control the degree of deceleration, the effect of emergency braking is poor, and different brake shoe action processes cannot be realized. Traditional hydraulic and pneumatic brakes The energy transfer route is longer and the energy conversion times are more
