Abstract
The utility model relates to an auxiliary device for an automobile brake system. The utility model is characterized in that an air inlet regulating gate is arranged in an air inlet pipe of an engine, and is driven by booster rams of exhaust automatic valves; two exhaust gates are arranged in an exhaust pipe of the engine side by side, and are driven by the booster rams of the exhaust automatic valves; air pipes of two booster rams of the exhaust automatic valves are provided with electromagnetic valves which are controlled by one control switch. When the automobile speed is fast, and the braking is required, the device can effectively reduce the rotation speed of the engine, can improve the braking reliability and can prolong the service life of a brake and the engine. When the automobile is in a long slope downgrade, or on a sleet road surface, the device can cause the engine to safely decelerate, can protect the engine and can prevent the automobile side slipping.
Description
Technical field
The utility model relates to auxiliary brake device for automobile.
Background technology
The braking of automobile is finished by brake system.But, in case of emergency, because the brake facing overheating failure can take place in the too fast glancing impact that needs of the speed of a motor vehicle, or the problem of brake failure; Another kind of situation is, when vehicle runs into long slope descending, or when running into the sleet sky, driving engine is during brake snub, fragile driving engine and drg on the one hand, and vehicle easily breaks away on the other hand, causes the accident.
Summary of the invention
The purpose of this utility model is: provide a kind of under the prerequisite that does not change brake system of car, can reduce the automobile brake system auxiliary device of engine speed.
The technical solution that realizes the foregoing invention purpose is such:
The automobile brake system auxiliary device comprises diesel motor, it is characterized in that:
A, in the air inlet pipe of diesel motor, be provided with the air inlet adjustment door, the door-hinge of air inlet adjustment door extends outside the air inlet pipe, the door-hinge overhanging end is connecting the piston rod of exhaust automatic valve servo cylinder by connecting rod, and exhaust automatic valve servo cylinder is being communicated with air receiver by tracheae, and tracheae is provided with the air inlet pipe electromagnetic valve;
B, in the freeing pipe of diesel motor, be provided with two exhaust valves side by side, two exhaust valve door-hinges extend outside the freeing pipe, connect by connecting rod between the two door-hinge overhanging ends, one side door axle overhanging end connects the piston rod of exhaust automatic valve servo cylinder, exhaust automatic valve servo cylinder is being communicated with air receiver by tracheae, and tracheae is provided with the freeing pipe electromagnetic valve;
C, air inlet and exhaust piper electromagnetic valve are connecting master cock by lead.
The utility model is by setting up the air inlet adjustment door, set up two exhaust valves reduce air input of engine by air and increase the exhaust stroke resistance by closing valve in the exhaust pipe of engine in engine air inlet tube, thereby reaches the purpose of improving engine braking effect.This device is very fast and need glancing impact at automobile speed, can effectively lower engine speed, improve the braking reliability, avoid driving engine to be damaged because of inertia is excessive, preventing that the speed of a motor vehicle is too fast makes the overheated or brake failure of brake facing, prolongs the service life of drg and driving engine.Automobile can make engine health slow down by this device when running into long slope descending or running into the sleet road surface, and the protection driving engine prevents defective steering stabilizer.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is an air inlet pipe stop mechanism scheme drawing,
Fig. 3 is a regulation of exhaust gas actuation mechanism scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated by embodiment.
Embodiment:
The automobile brake system auxiliary device has improved the admission gear and the exhaust gear of diesel motor, and concrete structural development scheme is as follows:
In the air inlet pipe 1 of diesel motor, air inlet adjustment door 2 is installed, the door-hinge of air inlet adjustment door 2 extends outside the air inlet pipe 1, the door-hinge overhanging end is connecting the piston rod of exhaust automatic valve servo cylinder 4 by connecting rod 3, exhaust automatic valve servo cylinder 4 is being communicated with air receiver 6 by tracheae 5, and air inlet pipe electromagnetic valve 7 is housed on the tracheae 5; See Fig. 2.
Two exhaust valves 9 are installed in the freeing pipe 8 of diesel motor side by side, the door-hinge of two exhaust valves 9 extends outside the freeing pipe 8, connect by connecting rod 10 between the two door-hinge overhanging ends, one side door axle overhanging end connects the piston rod of exhaust automatic valve servo cylinder 4, exhaust automatic valve servo cylinder 4 is being communicated with air receiver 6 by tracheae 5, and tracheae is provided with freeing pipe electromagnetic valve 11; See Fig. 3
Air inlet and exhaust piper electromagnetic valve 7,11 is connecting same master cock by lead.
In high vehicle speeds, need glancing impact, touching on the brake simultaneously, press the master cock of the utility model device, air inlet and exhaust piper electromagnetic valve 7,11 moves simultaneously, under the effect of two exhaust automatic valve servo cylinders 4, air inlet adjustment door 2 apertures in the air inlet pipe 1 reduce, and reduce suction quantity, increase the engine stroke resistance; Two exhaust valves 9 in the freeing pipe 8 cut out, and increase the exhaust stroke resistance, thereby reach the effect of Jake brake.
When this device is used for the blow-fed engine machine, in the blwr pipeline, should install an exhaust solenoid valve additional, and this electromagnetic valve is by the master cock control identical with the air inlet and exhaust piper electromagnetic valve.
