Description
Technical field
The utility model relates to a kind of petrol engine, specifically, is a kind of petrol engine that is used for the band brake device on the mowing machine.
Background technique
At home, equal brakeless device on the present petrol engine, during shutdown, petrol engine relies on the inertia of its flywheel to slow down gradually, until stopping.Shutting down from the flywheel that shuts down needs the long time of cost, during used as the power equipment of mowing machine, security incident takes place easily, causes the infringement of human, financial, and material resources.Abroad, though on some petrol engine braking device is installed, this braking device can not directly be applied on the petrol engine of China.
Summary of the invention
The purpose of this utility model provides a kind of petrol engine that is useful in the band brake device on the mowing machine.Technical problem to be solved is by braking device is installed, to realize the purpose of petrol engine fast braking.
The technological scheme of the utility model technical solution problem is: a kind of petrol engine of band brake device, comprise crankcase and flywheel, it is characterized in that being equipped with on the crankcase brake arm dunnage, the brake arm dunnage is connected with the brake arm combination by bearing pin, the brake arm combination is triangular in shape, the upper end is connected with drag-line on the operating grip, the lower end is equipped with brake pad, right-hand member is equipped with switch contact, extension spring one end hangs over brake arm combination upper end, the other end hangs on the left external part of brake arm dunnage, and brake arm dunnage right-hand member middle part is equipped with the leaf support combination.
Therefore the utility model, can realize the fast braking to petrol engine owing on the crankcase of petrol engine braking device has been installed, and during used as the power equipment of mowing machine, can effectively prevent the generation of security incident, avoids causing the infringement of human, financial, and material resources.
The utility model has the advantages that: on the basis that does not change former petrol engine structure, increased braking function, its compact structure, good braking effect.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is that the A of Fig. 1 is to rotation diagram.
Embodiment
The utility model is described in further detail in conjunction with the accompanying drawings:
Please see Figure 1, Fig. 2, the utility model mainly is made up of brake arm dunnage 1, extension spring 2, brake arm combination 3, leaf support combination 4, bearing pin 5, pin sleeve 6, switch contact 7, brake pad 8, flywheel 9, crankcase 10 and petrol engine miscellaneous part.Structure outline of the present utility model is: brake arm dunnage 1 is installed on the crankcase 10, brake arm dunnage 1 is connected with brake arm combination 3 by bearing pin 5, it is 3 triangular in shape that brake arm makes up, the upper end is connected with drag-line on the operating grip, the lower end is equipped with brake pad 8, and right-hand member is equipped with switch contact 7, and extension spring 2 one ends hang over brake arm and make up 3 upper ends, the other end hangs on the left external part of brake arm dunnage 1, and brake arm dunnage 1 right-hand member middle part is equipped with leaf support combination 4.
As shown in Figure 2: in the brake arm combination 3 pin sleeve 6 is installed also.
As shown in Figure 1: brake arm dunnage 1 is fixing by 2 bolts and crankcase 10.
Working principle of the present utility model is: during startup, drag-line pulling brake arm combination 3 clockwise rotates around bearing pin 5 relative brake arm dunnages 1, extension spring 2 elongations, brake pad 8 leaves flywheel 9, and simultaneously, switch contact 7 is separated with leaf support combination 4, petrol engine is flame-out, switch disconnects, gasoline engine starting, flywheel 9 runnings.During shutdown, drag-line is loosening, extension spring 2 returns, brake arm combination 3 rotates counterclockwise around bearing pin 5 relative brake arm dunnages 1, and switch contact 7 makes up 4 with leaf support and contacts, and petrol engine stops working, switch connection, petrol engine quits work, and brake pad 8 contacts with flywheel 9 and produces friction brake force, and flywheel is shut down rapidly.
