Description

The utility model relates to a vehicle, in particular, to a military tracked vehicle (VGM), which includes a power plant with an internal combustion engine (ICE) equipped with a device for monitoring the coolant level (coolant) of the power plant cooling system.

The technical result of using the above device is to increase the operational reliability of a military tracked vehicle by monitoring the coolant level. Monitoring allows timely action to be taken to prevent engine damage in the event of loss of coolant.

The technical result is achieved by installing a coolant level control device, which includes a coolant level sensor, a coolant level control button and a control lamp, controlled by a level control unit.

Known technical solution [1, patent 2526132], providing prevention of failure of the internal combustion engine during operation of the vehicle in the event of partial or complete loss of coolant in the cooling system by installing alarm devices for the critical differential pressure of the coolant in the water pump and automatic activation of the mechanism stopping the engine when a critical pressure drop in the said water pump is reached. A fairly complex system, acceptable for a vehicle equipped with a microprocessor unit for processing sensor signals, actuators and information display facilities that ensure the operation of the system in automatic mode, without the participation of the driver. Also, an analogue can be the invention [2, patent 2166210], which protects the device for maintaining the optimal operating mode of the power plant units. Harmonization of the signals from the sensors of fluids, the level of contamination of the air cleaner through a dedicated electrical network allows for signaling and shutdown of the power plant when the limit operating values of the parameters are reached. The system is complex, it requires a "different" (as in the text of the patent description) electrical network and mounting sensors in the cooling system, lubrication system, air supply system.

The closest analogue of the claimed utility model can be the "Fuel and coolant level indicator .." [3, patent PM 114150], which makes it possible to carry out the necessary measurements during vehicle maintenance, ie. practically in stationary conditions.

The device proposed as a useful model for monitoring the coolant level in the chassis of a military tracked vehicle with an internal combustion engine makes it possible to monitor the level in any conditions, in the operating mode of the power plant. At the same time, the risk of an emergency shutdown of the vehicle engine is minimal. The technical result of the use of the above device is to increase the operational reliability of a military tracked vehicle due to the implementation of reliable control over the coolant level of the power plant cooling system, timely prevention of engine damage in case of loss of coolant and maintaining the specified tactical and technical characteristics of the military tracked vehicle during operation.

The utility model "Device for monitoring the level of the coolant of the power plant of a military tracked vehicle" is illustrated by FIG. 1 in block diagram form. Functional elements of the block diagram:

internal combustion engine - the power plant of a military tracked vehicle;

expansion tank of the cooling system - the unit of the cooling system of the power plant, in which the coolant level sensor is installed;

control unit - a control unit for a coolant level control device, electrically connected to a control lamp, a coolant level control button, a control lamp health control button and operating from the on-board electrical network of a military tracked vehicle;

a coolant level sensor installed in the expansion tank of the power plant cooling system, with a float-type coolant level sensing element, which provides an electrical signal to the warning lamp;

coolant level control button, which is turned on to supply the voltage of the on-board network of the VGM to the control lamp;

button for monitoring the serviceability of the warning lamp, by turning on which the serviceability of the warning lamp is checked;

control lamp - a basic element of equipment that provides an indication of the level of the coolant in its absence or when the level falls below the permissible level;

on-board electrical network - a source of electrical power for the coolant level control device.

The utility model works as follows. With a sufficient coolant level, the float of the coolant level control sensor is in the upper position, while an electrical signal is not issued to the warning lamp.

In the absence of coolant or when its level drops below the permissible level, the float of the coolant level sensor goes down, while the coolant level sensor gives an electrical signal to trigger the warning lamp.

To control the completeness of the cooling system filling, the coolant level control button is pressed, while if the coolant level is insufficient, the control lamp lights up, with a sufficient coolant level, the control lamp does not light up.

To control the serviceability of the warning lamp, you must press the button for monitoring the serviceability of the warning lamp.

The control unit provides for the pairing of electrical signals from the coolant level sensor, the control lamp, the coolant control button, and the control lamp health control button.

The use of the device eliminates the need for the crew to leave the vehicle, open hatches and fillers, search for and use a dipstick to control the coolant level, etc.

The applicant is not aware of a similar solution for monitoring the coolant level. The technical solution declared as a useful model has a sufficient technical level, is practically acceptable and achieves the declared technical result, which consists in increasing the operational reliability of a military tracked vehicle by monitoring the coolant level of the power plant cooling system. Monitoring allows you to take timely measures to prevent damage to the engine in case of loss of coolant and maintain the specified tactical and technical characteristics of a military tracked vehicle during operation.
