Anonymous users2024-02-07The working principle of the brake drum is the principle of inhaling air when the engine is working, causing a vacuum on one side of the booster, and the pressure difference relative to the normal air pressure on the other side, using this pressure difference to strengthen the braking thrust.
When driving in water, the wheels are almost all immersed in the water, making the brake pads.
A layer of water is left between the brake drum and the brake drum, as if lubricating oil is applied, so that the friction between the brake pads and the brake drum is made.
Reduced, the car cannot be controlled, and the water in the drum is not easy to escape.
This phenomenon of brake failure comes very quickly, after walking away from the water while stepping on the brakes, several times in a row, the water droplets between the brake pads and the brake drum will be wiped off, at the same time, the heat generated by the friction will dry it, so that the brakes will quickly return to the original sensitivity.

Anonymous users2024-02-06The gearbox drum is also called a hydraulic torque converter, which transmits engine power and reduces the impact of shifting, which is equivalent to the semi-linkage state of the manual transmission clutch, and locks it after the speed comes up. The power is transmitted directly to the gears.
The torque converter is the component in the automatic transmission that transmits the power from the engine flywheel, replacing the clutch on the traditional manual transmission. Fluid torque converter is a hydraulic element composed of a pump wheel, a turbine, and a guide wheel. Installed between the engine and the transmission, the hydraulic oil (ATF) is used as the working medium to transmit torque, torque conversion, speed transmission and clutch.
Hydraulic torque converter is a non-rigid torque converter with liquid as the working medium, which is one of the forms of hydraulic transmission. It has a closed working chamber in which the liquid circulates and flows, in which the pump wheel, turbine and guide wheel are connected to the input shaft, output shaft and housing respectively. When the power engine (internal combustion engine, electric motor, etc.) drives the input shaft to rotate, the liquid flows out of the centrifugal pump in turn, passes through the turbine, the guide wheel and then returns to the pump wheel, and circulates repeatedly.
The pump wheel transfers the mechanical energy from the input shaft to the liquid. The high-speed liquid pushes the turbine to rotate, transferring energy to the output shaft. Torque converters transmit torque by the interaction of the liquid with the blades to produce a change in momentum moment.

Anonymous users2024-02-05Automotive drums, also known as vacuum boosters, work by using vacuum (negative pressure) to increase the force exerted by the driver on the pedals.
The vacuum booster is generally located between the brake pedal and the brake master cylinder, and for ease of installation, it is usually combined with the master cylinder as a single component, and a portion of the master cylinder is deep into the vacuum booster housing.

Hehe, I'm a tuning technician, (self-taught) Hehe, first of all, please LZ don't underestimate the modified exhaust system. There are many types of exhaust system modifications for automobiles. It can be divided into the middle section of the head coke (plantain) and the tail end. >>>More
1. Transmitter.
The transmitter is composed of a transmitter switch, a transmitter antenna (key board), an integrated circuit, etc. It is integrated with the signal transmission circuit on the key board. From the identification of the ** memory circuit to the FSK modulation circuit, the lithium battery of the button type is installed on the opposite side of the circuit due to the miniaturization of the use of a single-chip integrated circuit. >>>More
If LNG is used in vehicles, it is mainly for vehicles with diesel engines. Because LNG itself is a cryogenic liquid with extremely high temperature requirements, the minimum capacity of LNG cylinders is more than 100 liters, so there is no trolley modified LNG at present. There are currently two ways to modify LNG vehicles, one is single-fuel and the other is dual-fuel. >>>More
1. The reason why automobile tires need to be dynamically balanced is that they need to be dynamically balanced when replacing new tires or after tire disassembly and assembly. It is usually impossible to distribute the weight evenly 100% after the tire is mounted on the rim, use a balancing machine to test the balance of the tire rim in a sports situation, and use a balance weight counterweight at the unbalanced point to ensure that the tire can run smoothly and avoid shaking. >>>More
It's better to change it, if you get a flat tire at high speed, especially the front wheel, the direction will not be able to hold up!!
