What is the function of a brake wheel cylinder?

1 Answers

The brake wheel cylinder is an indispensable component of the braking system. Its primary function is to push the brake shoes, which then rub against the brake drum to decelerate or stop the vehicle. When the brake pedal is pressed, the master cylinder generates thrust to force hydraulic fluid into the wheel cylinders. The pistons inside the wheel cylinders move under hydraulic pressure, pushing the brake shoes. The hydraulic brake system consists of a master cylinder and a brake fluid reservoir. One end connects to the brake pedal, while the other connects to the brake lines. The master cylinder contains brake fluid with inlet and outlet ports. When braking, the outlet port opens while the inlet port closes. Under the pressure of the master cylinder piston, brake fluid is forced through the lines to each wheel cylinder to perform braking. Upon releasing the brake pedal, the master cylinder's outlet port closes and the inlet port opens, allowing brake fluid to flow back from the wheel cylinders to the master cylinder, returning to the original state.

What is the function of a thrust bearing?

Thrust bearings are used to withstand the axial thrust of the rotor during operation, determining and maintaining the axial relative position between the turbine rotor and the cylinder. Thrust bearings can be designed as standalone units or integrated with support bearings, known as combined-type bearings. Structurally, they are categorized into multi-jaw type and sector tile type, with the sector tile type being the most commonly used today. The main components of a thrust bearing include working tiles, non-working tiles, adjusting shims, and mounting rings. On both sides of the thrust collar, ten to twelve working tiles and non-working tiles are installed, each mounted on the mounting ring. The working tiles bear the forward axial thrust of the rotor, while the non-working tiles bear the reverse axial thrust of the rotor.

What are the reasons for the sudden heaviness of the steering wheel?

The reasons for the sudden heaviness of the steering wheel are: 1. Insufficient tire pressure; 2. Contaminated power steering fluid; 3. Internal failure of the power steering system; 4. Poor bearing lubrication. The working principle of the car steering wheel is to transmit torque to the rack and pinion mechanism, thereby pushing the wheels to turn left or right. The solutions for sudden heaviness of the steering wheel are: 1. Refill the power steering fluid; 2. Replace the circuit fuse; 3. Replace the flat bearing and replenish the kingpin grease; 4. Add lubricating oil to the steering tie rod ball joint. Steering wheels are categorized into: single-spoke steering wheel, dual-spoke steering wheel, three-spoke steering wheel, and four-spoke steering wheel.

How to Determine if a Tire is Underinflated?

Methods to determine if a tire is underinflated include: 1. Visually inspect all four tires to see if any appear noticeably flat; 2. Use a tire pressure measurement device, such as a handheld tire pressure monitor or an onboard tire pressure display, to accurately measure the tire pressure; 3. Install a tire pressure monitoring system to continuously monitor the tire pressure in real-time. Causes of underinflation: Damage to the tire sidewall or inner edge. Some drivers have poor spatial awareness and frequently scrape the tire sidewalls against curbs, leading to gradual wear of the sidewalls. Damage to the inner edge of the tire is usually caused by improper handling during tire mounting or dismounting from the wheel rim, often occurring during the installation of new tires or after tire repairs. Damage to the tire sidewall or inner edge can result in slow leaks and significantly increase the risk of a tire blowout.

What is the solution for a tire pressure monitoring system malfunction?

The solution for a tire pressure monitoring system malfunction is: 1. Display the tire pressure and temperature readings on the dashboard to check for any abnormalities; 2. Inspect the underinflated tire for any air leaks; 3. Check if the tire pressure monitor is malfunctioning. The causes of a tire pressure monitoring system malfunction are: 1. Punctured tire; 2. Prolonged driving or failure to replenish tire pressure in time; 3. Faulty tire pressure sensor; 4. Failure to reset the tire pressure module after tire replacement or repair. The functions of the tire pressure monitoring system are: to prevent accidents, prolong tire service life, and reduce wear on the suspension system.
