Abstract
The utility model discloses an engine exhaust braking unit which comprises an accumulator and a throttle sensor. The throttle is installed on the throttle operating point,; the accumulator, a cab electric, a exhaust braking switch, the throttle sensor and a exhaust braking solenoid valve are connected in line in turn; the controlled port air passage of the exhaust braking solenoid valve is connected with the engine exhaust braking unit. The utility model is capable of preventing the engine stall and ensuring the automobile safety during exhaust braking operation, achieves the advantages of high automaticity, high working efficiency, simple structure, low cost and convenient mounting, and is applicable for rode automobile widely.
Description
Technical field
The utility model relates to the engine exhaust complemental brake system that a kind of motor vehicle use when lower long slope or Reduced Speed Now.
Background technique
The engine exhaust complemental brake system that known motor vehicle use when lower long slope or Reduced Speed Now generally is by the manipulation exhaust brake switch, control engine exhaust butterfly valve, and then the exhaust realization of control motor.If in implementing the exhaust brake process, strengthen engine throttle or gearbox is carried out gear shift, motor may not stop working because exhaust is not smooth, so not only do not reach the purpose of vehicle deceleration, and as the air pump of service brake energy supply with provide the steerig pump of power can not work because of engine misses by motor, the safety of influence driving.
Summary of the invention
The purpose of this utility model is that a kind of engine exhaust and brake device will be provided, and this device can prevent engine misses when motor vehicle lower long slope or Reduced Speed Now braking, guarantee traffic safety.
The purpose of this utility model is achieved in that this device comprises storage battery and throttle sensor, throttle sensor is installed in the power control place, storage battery, operator cabin are electric, exhaust brake switch, throttle sensor and exhaust brake solenoid valve are contacted in proper order, and the controlled implication road of exhaust brake solenoid valve links to each other with the engine exhaust and brake device.
Also clutch sensor can be installed in the clutch control place, clutch sensor is connected between exhaust brake switch and the throttle sensor.
Throttle sensor is installed at the engine oil-valve operation place, as long as the relative engine idle of power control has the variation of acceleration, sensor is just exported the signal of accelerator pedal action.
At the clutch control place clutch sensor is installed,, is illustrated that the driver has the hope of gear shift, the signal of sensor output clutch action as long as clutch is operated.
As required, the motor vehicle of some road running also can only be installed a throttle sensor at the power control place.
Any one disconnection in exhaust brake switch, throttle sensor and the clutch sensor illustrates that the driver has closed exhaust brake switch, has perhaps handled engine throttle pedal or clutch, the solenoid valve outage, and exhaust brake condition is removed.In case pilot control exhaust brake switch, and throttle sensor and clutch sensor all do not detect the signal of wishing action, solenoid valve has electricity, the exhaust brake action is implemented.
The utlity model has the flame-out function of preventing engine, guarantee the safety of vehicle when exhaust brake is implemented, the automaticity height, high working efficiency, simple in structure, cost is low, is convenient to install, and is easy to promote.Can on the motor vehicle of road running, be extensive use of.
Description of drawings
Fig. 1 is an an embodiment's of the present utility model scheme of installation.
Electric, 2. exhaust brake switch, 3. clutch control, 4. clutch sensor, 5. power control, 6. throttle sensor, 7. exhaust brake solenoid valve, 8. engine exhaust and brake device, 9. storage battery of 1. operator cabins among the figure.
Embodiment
In Fig. 1, clutch sensor 4 is installed in clutch control 3 places, throttle sensor 6 is installed in power control 5 places.Electric 1 storage battery 9, operator cabin in order, exhaust brake switch 2, clutch sensor 4, throttle sensor 6 and exhaust brake solenoid valve 7 polyphones get up.The controlled implication road of exhaust brake solenoid valve 7 and engine exhaust and brake device 8 are coupled together.If clutch sensor 4 is not installed, can coupled circuit directly be coupled together, be equivalent to detect all the time not action of clutch.
Depress clutch control 3, adjust clutch sensor 4, make the clutch sensor 4 can the omnidistance action that detects clutch control 3, the output action signal.Depress power control 5, adjust throttle sensor 6, make the throttle sensor 6 can the omnidistance action that detects power control 5, the output action signal.
Claims (2)
1. engine exhaust and brake device, this device comprises storage battery and throttle sensor, it is characterized in that throttle sensor is installed in the power control place, storage battery, operator cabin are electric, exhaust brake switch, throttle sensor and exhaust brake solenoid valve are contacted in proper order, and the controlled implication road of exhaust brake solenoid valve links to each other with the engine exhaust and brake device.
2. engine exhaust and brake device according to claim 1 is characterized in that clutch sensor is installed in the clutch control place, and clutch sensor is connected between exhaust brake switch and the throttle sensor.
