Abstract
The utility model is an exhaust-retarding auxiliary braking mechanism for the single-cylinder vehicle. The utility model comprises an exhaust throttle system which is connected with a control handle, and a synchronous flameout system. The utility model avoids the disadvantage that the single-cylinder tricar only depends on the driving braking system. When the vehicle is running on the road with long descending slope, the driving braking system can not be used or can be seldom used, and through the structure of the utility model, the kinetic energy of the sliding of the car is converted to be the heat energy which is generated after the engine compresses the air, and then the heat energy is consumed by the heat dissipation system of the engine, the velocity of the car is made to be decreased or kept, and the driving safety is ensured, the high-temperature failure caused by the frequent use of the driving braking system is avoided.
Description
Technical field
The utility model is the slow formula auxiliary brake mechanism of a kind of single cylinder automobile exhaust gas.
Background technology
At present the single cylinder three wheeled motor vehicle has generally only disposed the service brake emergency brake system of unifying, and the automobile that mainly travels on mine or the mountain highway is often wanted lower long slope, for not making automobile under action of gravity own, constantly accelerate to hazard level, should continue braking to automobile, will change into heat energy again and dissipation by that part of kinetic energy that potential energy changes into.In this case, depend merely on service braking system and be difficult to finish the braking task, because the long-time frequent operation of drg will make its temperature increase greatly, so that brake efficiency decline even entirely ineffective.
Summary of the invention
The purpose of this utility model, provide the slow formula auxiliary brake mechanism of a kind of later-model single cylinder automobile exhaust gas, its relevant portion is installed in the engine fuel injection pump control mechanism of vehicle and the corresponding position of freeing pipe, can change into heat energy to the potential energy in the vehicle traveling process by the engine compresses air, and through the cooling system dissipation of driving engine, thereby overcome the limitation that former single cylinder vehicle only relies on service brake, do not using or using less under the situation of service brake, also can make the car speed reduction or keep stable, thus the safety that improves vehicle '.
The utility model comprises and control handle bonded assembly exhaust throttle system and synchronous shutdown systems.The utility model in use, the control handle bonded assembly be used to be installed on the freeing pipe the exhaust throttle system and be used for driving engine on fuel regulator valve bonded assembly shutdown systems, two operations are carried out synchronously.Under normal condition, blow off valve is in full-gear, normal vehicle operation.When needing exhaust slow, the pull-up control handle, can control engine fuel control cock stop control lever, make engine off, and gas exhaust duct is stopped up, automobile drives engine crankshaft by drive wheel and transmission system and continues rotation in the process of sliding, thereby is that the driving engine of car power source just becomes consumption automobile kinetic energy plays retarded acting to automobile air compressor originally.In this case, automobile consumes in air inlet in board, compression, the exhaust process the kinetic energy of driving engine input is most of, and fraction is consumed in the driving of annexes such as water pump, oil pump, electrical generator.The moment that driving engine and above-mentioned each annex hinder crankshaft revolution promptly is lock torque, passes to drive wheel after will amplifying by transmission system, finishes the retarded acting to car load.
After the utility model is stated control on the implementation, can adopt multiple mode (as manual mode) to make the control mechanism return of exhaust throttle system and make shutdown systems not influence the stroke of fuel regulator valve, but preferably Bringing-back mechanism and elasticity control mechanism are set at control mechanism.Specifically, it comprise be installed in and the rocking arm of control handle bonded assembly drag-line and exhaust throttle valve control system between spring and and the fire extinguishing line of control handle bonded assembly drag-line and control shutdown systems between spring.Like this, under the situation of not implementing energy brake, do not influence the play motion of fuel regulator valve; When the control exhaust shutter, under the situation of not implementing energy brake, make exhaust shutter return to full open position of coupler, do not influence the normal operation of driving engine.
In the utility model,, can adopt a rocking arm to exhaust shutter control, rocking arm directly is connected; the limiting stopper of the restricted exhaust shutter full open position of coupler of rocking arm one side, drag-line is connecting control handle and rocking arm, between drag-line and the rocking arm spring is housed with exhaust shutter.
In addition, the control handle control that exhaust shutter and fire extinguishing line can be by separately, but they preferably are connected with same control handle, thus be convenient to synchro control, reach the optimum efficiency of braking.
And for control handle can be located when the implementation and operation, the position self-locking mechanism should be set, its concrete structure can adopt with handbrake mechanism for motor vehicle in the corresponding identical structure of self-locking mechanism.
The utility model has avoided the single cylinder three wheeled motor vehicle only to rely on the drawback of service brake.When automobile travels on long descending highway, can not use or use less service braking system, the kinetic energy of automobile slide is converted into the heat energy that produces behind the engine compresses air by the utility model structure, then launched machine cooling system consumes, car speed is reduced or maintenance, guaranteed traffic safety, the high temperature failure of having avoided the frequent use of running brake to cause.
