The upper part includes carbon steel plates, hydraulic cylinders, power take-offs, lifting devices, warning lights, hydraulic winches, etc. Regarding the accessories on the fire truck, let me tell you here: When buying Isuzu fire trucks and Isuzu fire truck accessories, you should pay attention to it. The cheap ones will definitely not be good. Although the original accessories are slightly higher in price than those wholesaled from outside, the original ones can be used normally without a running-in period after being purchased. However, the items in the wholesale market look the same and have the same model number. After installation, a running-in period is required. After the running-in period, other parts will be worn out.

Fire truck engine: The engine is the power device of the Isuzu fire truck. It consists of a body, a crank connecting rod mechanism, a valve train, a cooling system, a lubrication system, a fuel system and an ignition system (diesel engines do not have an ignition system). According to the fuel, there are two types of engines: gasoline and diesel engines; according to the working mode, there are two types: two-stroke and four-stroke engines. Generally, engines are four-stroke engines. The working process of a four-stroke engine: A four-stroke engine is a piston that reciprocates four strokes to complete a working cycle, including the four processes of intake, compression, power, and exhaust. The four-stroke diesel engine undergoes the same process of intake, compression, power and exhaust as the gasoline engine. But the difference from the gasoline engine is that the gasoline engine is ignited, while the diesel engine is compression ignition.

Cooling system: Generally composed of water tank, water pump, radiator, fan, thermostat, water temperature meter and water release switch.The Isuzu fire truck engines use two cooling methods, namely air cooling and water cooling. Generally, engines use water cooling.

Lubrication system: The Isuzu fire truck engine lubrication system consists of oil pump, filter collector, oil filter, oil passage, pressure limiting valve, oil gauge, pressure sensing plug and oil dipstick.

Fuel system: The fuel system of a gasoline engine consists of a gasoline tank, a gasoline meter, a gasoline pipe, a gasoline filter, a gasoline pump, a carburetor, an air filter, an intake and exhaust manifold, etc.

Carburetor: It is a device that mixes gasoline and air in a certain ratio into an atomized gas. This atomized gas is called a combustible mixture, which is supplied into the cylinder in an appropriate amount in a timely manner.

The chassis of the Isuzu fire engine: its function is to support and install the car engine and its components and assemblies, forming the overall shape of the car, and receiving the power of the engine to make the fire truck move and ensure that the Isuzu fire truck can drive normally. The chassis of the Isuzu fire truck consists of four parts: transmission system, driving system, steering system and braking system.

1. Transmission system: The transmission system generally consists of clutch, transmission, universal transmission device, main reducer, differential and half shaft.

The function of the transmission system

   The power generated by the Isuzu fire truck engine is transmitted to the driving wheels through the transmission system. The transmission system has the functions of deceleration, speed change, reversing, power interruption, inter-wheel differential and inter-axle differential. The fire truck and the engine work together to ensure the normal driving of the fire truck under various working conditions and have good performance. Dynamic and economical. 

Types and composition of drive trains

The transmission system can be divided into mechanical transmission, hydraulic transmission, hydraulic transmission, electric transmission, etc. according to different energy transmission methods.　

2. Driving system: The driving system consists of the car's frame, axles, wheels (note) and suspension. 

   The frame, axle, wheels and suspension of the fire truck constitute the driving system. The function of the driving system is to receive the power of the transmission system and generate traction through the interaction between the driving wheels and the road surface, so that the fire truck can travel normally;

Bear the total weight of the Isuzu fire truck and the reaction force of the ground: mitigate the impact of uneven roads on the car body, attenuate the vibration of the car while driving, and maintain the smoothness of driving;

Cooperate with the steering system to ensure vehicle control stability.

3. Steering system: The special mechanism on a car used to change or restore its driving direction is called the car steering system.

The basic components of the steering system

   (1) Steering control mechanism mainly consists of steering wheel, steering shaft, steering column, etc. 

   (2) Steering gear is a mechanism that converts the rotation of the steering wheel into the swing of the steering rocker arm or the linear reciprocating motion of the rack shaft, and amplifies the steering control force. The steering gear is generally fixed on the car frame or body, and the steering control force usually changes the transmission direction after passing through the steering gear. 

   (3) Steering transmission mechanism is a mechanism that transmits the force and motion output by the steering gear to the wheels (steering knuckles) and deflects the left and right wheels according to a certain relationship. 

Types and working principles of steering systems

According to different steering energy sources, steering systems can be divided into two categories: mechanical steering systems and power steering systems.

4. Braking system: A series of specialized devices on a car that are used to cause the outside world (mainly the road surface) to exert a certain force on certain parts of the car (mainly the wheels), thereby forcibly braking it to a certain extent. They are collectively called brakes. dynamic system. Its function is: to force the driving car to slow down or even stop according to the driver's request; to make the stopped car park stably under various road conditions (including on slopes); to keep the speed of the car driving downhill. Stablize. 

The only thing that can brake a car is an external force that acts on the car and is opposite to the direction of travel of the car. The magnitude of these external forces are random and uncontrollable. Therefore, a series of special devices must be installed on the fire truck to brake the car. Implement the above functions.
