Brake device for general machine

Abstract

A mechanical brake is provided. The front end of a braking arm is hinged on the surface of a base plate, the rear end of the braking arm passes through the stripe type hole located at the connection point between the base plate and a support plate; at the end of the rear end of the braking arm, a dragline-installing hole is provided; and between the body of the braking arm and the end of the support plate, a spring is hung; from the body at front of the braking arm, a branch arm extends; on the cantilever end of the branch arm, a friction plate assembly is mounted; on the base plate beside the branch arm, a rubber seat is provided; on the rubber seat, a cut-out spring leaf is mounted, one end of which is connected with a cut-off wire, another end is suspended; on the outer edge of the branch arm, a cut-off arm stretching out is fixed. Before the braking arm rotates about the hinging point at front end to brake, the cut-off arm first contacts with the bottom of the suspended part of the cut-off spring leaf. The invention employs a ''first cut-off then brake'' way, can minimize the braking time, guarantee the braking effect; and effectively reduce the wear of the friction plate assembly, and greatly lengthen the service life.

Description

technical field [0001] The invention relates to a gasoline engine component, in particular to a brake device for a general machine. Background technique [0002] At present, the general-purpose brake device generally adopts the method of braking and flameout at the same time, that is, pulling the cable to make the brake arm rotate around the hinge point between it and the base plate, and the spring hooked between the brake arm and the base plate is pulled. Stretch, the friction plate assembly fixed on the brake arm leaves the circumferential surface of the gasoline engine flywheel; at the same time, the flameout switch connected to the flameout wire is disconnected, the control circuit of the entire gasoline engine is in the open state, and the gasoline engine can be started at this time. When braking is required, loosen the cable, and under the force of the spring, the brake arm is reset, and the friction plate assembly on the brake arm is pressed against the circumferentia...

AI Technical Summary

Problems solved by technology

Since the flameout switch uses a micro switch, the sensitivity and stability are poor. When braking and flameout are performed at the same time, due to the poor contact of the flameout switch, it is easy to cause the friction plate assembly to be attached to the flywheel and the gasoline engine has not yet It can be turned off, that is, the power acting on the flywheel fails to stop output in time, which will not only cause a lot of wear and tear of the friction plate assembly, shorten its service life, but also the braking time of the flywheel is longer. If it is used on a lawn machine, it cannot meet the requirements of the flywheel system. Relevant requirements that must be stopped within 3 seconds when moving
