Abstract
A linkage brake control device of a diesel vehicle comprises an exhaust brake solenoid valve, an exhaust brake valve, an air circuit and a switch circuit, and is characterized in that a valve of the exhaust brake valve is installed in an engine exhaust pipe, a valve control end of the exhaust brake valve is connected with an air source through the exhaust brake solenoid valve by the air circuit, and a coil of the exhaust brake solenoid valve is connected with a power supply through the switch circuit controlled by a neutral switch (3) and a brake switch (4). The utility model is suitable for a diesel automobile, at the diesel automobile in-process of driving, when the driver steps on brake pedal, stopper and engine exhaust braking simultaneous working, the exhaust braking is relieved when the neutral is hung to the car to made things convenient for the driver to operate, strengthened the automobile braking nature, the security has alleviateed the wearing and tearing of brake shoe simultaneously.
Description
Technical field
The utility model relates to the automobile brake technical field, relates in particular to a kind of diesel car interlock braking force control system.
Background technology
The running car brake system mainly adopts the friction brake braking at present.Through the mountain area traveling automobile of being everlasting, if be the purpose of stabilizing speed when reaching lower long slope with travelling brake only, then may cause brake overheating and reduce brake efficiency, in addition entirely ineffective.Therefore taking auxiliary braking when the brake system that travels plays a role is necessary to strengthen brake efficiency.Engine exhaust and brake has been widely used on the diesel car brake system as a kind of auxiliary braking mode.
Usually the mode of engine exhaust and brake mainly relies on chaufeur to stir the purpose that control handle reaches the unlatching energy brake, but there is inconvenience in actual applications in this mode.For example, usually driver habit brakes in the mode of stepping on brake pedal, forgets often and stirs the energy brake control handle, thereby reduced the Occupation coefficient of energy brake, can not bring into play its function well; When travel in this busy highway section, external city, use energy brake to stir control handle continually, make troubles to driver's operation as need.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, a kind of diesel car interlock braking force control system that utilizes brake pedal control brake device braking simultaneously and engine exhaust and brake is proposed, to make things convenient for the control operation of chaufeur to energy brake, strengthen automobile braking performance, safety, the wearing and tearing that alleviated brake shoe brake cheek simultaneously.
The purpose of this utility model is achieved by the following technical solution, a kind of diesel car interlock braking force control system, comprise the energy brake electromagnetic valve, exhaust brake valve, gas circuit, switch circuit is formed, it is characterized in that: the valve of described exhaust brake valve is installed in the exhaust pipe of engine, the valve control end of exhaust brake valve is connected with source of the gas by the energy brake electromagnetic valve by gas circuit, the coil of described energy brake electromagnetic valve links to each other with power supply by the switch circuit of neutral switch 3 with brake switch 4 controls, when neutral switch 3 disconnects, during brake switch 4 closures, switch circuit is with the coil and the power connection of energy brake electromagnetic valve; When neutral switch 3 closures, switch circuit disconnects the coil and the power supply of energy brake electromagnetic valve.
Said switching circuit is by normally closed relay 1, normally opened relay 2, neutral switch 3, brake switch 4, energy brake electromagnetic valve 5 and direct supply are formed, the coil L1 of described normally closed relay 1 be connected between the direct supply both positive and negative polarity after neutral switch 3 is connected; The coil L2 of described normally opened relay 2 be connected between the direct supply both positive and negative polarity after brake switch 4 is connected; After connecting each other, the coil of the contact K1 of the described normally closed relay of direct supply, the contact K2 of normally opened relay and energy brake electromagnetic valve 5 is connected between the direct supply both positive and negative polarity.
The utility model is applicable to diesel car, in the diesel car driving process, when chaufeur is stepped on brake pedal, drg and engine exhaust and brake are worked simultaneously, energy brake was removed when automobile was hung neutral gear, thereby had made things convenient for driver's operation, strengthened automobile braking performance, safety, the wearing and tearing that alleviated brake shoe brake cheek simultaneously.
Description of drawings
Fig. 1 is the circuit diagram of the utility model switch circuit.
In the drawings, 1. normally closed relay, 2. normally opened relay, 3. neutral switch, 4. brake switch, 5. energy brake electromagnetic valve.
The specific embodiment
The utility model comprises energy brake electromagnetic valve 5, exhaust brake valve, gas circuit, switch circuit, the valve of described exhaust brake valve is installed in the exhaust pipe of engine, and the valve control end of exhaust brake valve is connected with energy brake electromagnetic valve 5, air receiver (source of the gas) by gas circuit.The coil of described energy brake electromagnetic valve 5 is by being linked to each other with power supply by the switch circuit of neutral switch 3 with brake switch 4 controls.
Described switch circuit is by normally closed relay 1, normally opened relay 2, and neutral switch 3, brake switch 4, energy brake electromagnetic valve 5 and direct supply are formed.Direct supply is the 24V power supply; The coil L1 of described normally closed relay 1 be connected between the direct supply both positive and negative polarity after neutral switch 3 is connected; The coil L2 of described normally opened relay 2 be connected between the direct supply both positive and negative polarity after brake switch 4 is connected; After connecting each other, the coil of the contact K1 of the described normally closed relay of direct supply, the contact K2 of normally opened relay and energy brake electromagnetic valve 5 is connected between the direct supply both positive and negative polarity.Neutral switch 3 places the automobile shift controller, and brake switch 4 places the automobile brake pedal place.
When the diesel car change speed gear box was hung D Drive, neutral switch 3 was in off-state, at this moment the contact K1 adhesive of normally closed relay 1.When chaufeur is stepped on brake pedal, brake switch 4 closures, the coil L2 energising of normally opened relay 2, thereby contact K2 adhesive, 5 energisings of energy brake electromagnetic valve are moved, and by gas circuit exhaust brake valve are closed, block the exhaust pipe of engine, reduce engine speed, energy brake is started working.When chaufeur hangs up neutral gear, neutral switch 3 closures, normally closed relay 1 coil L1 energising, K1 disconnects, and energy brake is removed in 5 outages of energy brake electromagnetic valve.
Although the foregoing description has been made detailed description to the utility model, but people can also make the modification that does not depart from its central idea to it, as the relay in the switch circuit is replaced with other common on-off element, it is reached equally when neutral switch 3 disconnections, during brake switch 4 closures, switch circuit is with the coil and the power connection of energy brake electromagnetic valve; When neutral switch 3 closures, switch circuit is with the coil and the open circuited function of power supply of energy brake electromagnetic valve.These modifications all belong to protection domain of the present utility model, and protection domain of the present utility model should be as the criterion with claims.
