The principle of the brake valve is mainly concerned with the equipment in the automotive brake system to ensure that the car can brake smoothly. Brake valves are divided into gas brake valves and hydraulic brake valves, which play a crucial role in the braking process of automobiles. The working principle and application scenarios of the gas brake valve and the hydraulic brake valve are different, but the common goal is to achieve the smooth and safe braking of the car

Hydraulic pump is a device that converts mechanical energy into hydraulic energy,  which drives the executive elements in the hydraulic system by producing high-pressure liquid. The working principle of  the hydraulic pump is to use mechanical energy to drive the rotor of the pump,  so that the liquid body in the pump chamber generates pressure,  and then the liquid is transported to the hydraulic system through the pipeline,  so as to achieve the control of the actuator.

A hub is a cylindrical, barrel-shaped metal component centered on an axle that supports the tire's inner rim. Also called ring, steel ring, wheel, tire bell. Wheel hub according to the diameter, width, molding methods, materials of different kinds.

1. The brake cylinder, also known as the master cylinder, is the operating rod of the brake pedal or brake device. It is mainly composed of gas column, piston, gasket, oil tank, oil flow device and so on.

2. The main parts of the cylinder are cylinder head, cylinder head, cylinder, piston, piston rod, guide sleeve, seal and pull rod.

1. The system constant pressure, such as the system water shortage, that is, when the pressure is reduced, the expansion tank will automatically water to the system, on the contrary, if the system pressure increases, the expansion tank can automatically eliminate excess water until the pressure is balanced.

2. Remove air from the system.

1. The air conditioning compressor plays the role of compressing the driving refrigerant in the air conditioning refrigerant circuit.

2. Air conditioning compressors are generally installed in outdoor units. The air conditioning compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. It dissipates heat into the air through the radiator. The refrigerant also changes from gaseous to liquid, and the pressure increases.

3. As the air conditioner compressor continues to work, it continuously absorbs heat from one end of the low-pressure area into the refrigerant and then sends it to the high-pressure area for dissipation into the air, thereby regulating the temperature.

(1) Evaporator for cooling liquid refrigerant. Used to cool liquid carrier coolants - water, brine or glycol solution. This type of evaporator commonly used are horizontal evaporator, vertical tube evaporator and spiral tube evaporator.

(2) evaporator for cooling air. This type of evaporator has a cooling tube and a cooling fan.

Shift handle (also known as transmission handle) is an important part of the automobile transmission system, mainly used to control the shifting operation of the automobile. In a traditional mechanical transmission, the shift handle transmits the shift operation to the gear mechanism inside the transmission through the connecting rod, thus achieving the switch of different gears. The principle of the shift handle mainly includes the following aspects:

1. Connection of joystick and shift lever

2. Operate the transmission mechanism

3. Control of gear mechanism

1. Screws on the commonly known as the teeth of the big name of the thread; screws with threads on the part of the screw; for the use of screwdrivers or wrenches to turn the screws to tighten or loosen the big head for the screws (screws) head; for use in conjunction with the machine screws, the middle of the hole with threads, screwed in the screws on the east to be called the screw cap (nut). The use of wood screws (generally used in woodworking, thread distance is wide, with a pointed), self-tapping screws (mostly used to connect wood, plastic or metal sheet, etc.) are not required to use the nut.
