What Is Shacman Truck Brake System?

The basic principle of the braking system is to utilize friction to convert the kinetic energy of the vehicle into thermal energy, thereby slowing or stopping the vehicle. Its main components include:

  1. Brake discs and drums: Brake discs are usually mounted on the wheels while drums are mounted inside the wheels. They are the key friction-generating components of the braking system. When braking is in effect, the brake pads come into contact with the discs or drums, generating friction that slows down the vehicle.
  2. Brake Pads: Brake pads are the friction material in contact with the brake disc or drum, and their quality and coefficient of friction have a direct impact on braking performance. They are usually made of wear-resistant materials to ensure durability and reliability for long-term use.
  3. Brake fluid: Brake fluid is the medium for transmitting force, converting the driver’s brake pedal pressure into braking force through the brake master cylinder. It has the characteristics of high temperature resistance, non-compressible and anti-corrosion to ensure the normal operation of the braking system.
  4. Brake Master Cylinder: The brake master cylinder is the key component controlling the flow of brake fluid and usually consists of a master cylinder and a booster. The master cylinder receives the force from the brake pedal and converts it into hydraulic pressure, which pushes the brake fluid to flow into the braking system to realize the braking function.

Daarby, the braking system of Shaanxi Trucks also includes auxiliary components such as brake lines, brake sub-pumps, and brake power distributors to ensure stable and reliable braking performance.

Types of Shacman Truck Brake System

Brake systems of the Shacman vehicle include traveling brake (footbrake), auxiliary brake (exhaust brake), emergency and parking brake(manual brake), and trailer brake (optional device), i.e. 4 sets of brake device in total.

1. Driving Brake

  • Pedal manipulation, dual circuit air brake. The maximum working pressure is 1MPa and the pressure regulating valve cutoff pressure is 1MPa. The first circuit acts on the rear axle (or double rear axle) wheels, and the second circuit acts on the front axle wheels. Once one of the two circuit drops below 0.55 MPa (5.5 bar), the air cylinder pressure indicator light is on. At this moment, park immediately and find out the cause of the pressure leak.
  • In a short period of time, performing full braking several times in succession may also cause the pressure drop below 0.55 MPa (5.5 bar)
  • Leak check: the engine stalls after the vehicle is full of gas, and the maximum pressure is 49 kPa within 2 hours or 10 kPa within 30 minutes after the hand brake is applied.

2. Auxiliary Brake

  • The auxiliary brake is controlled and operated by the button valve mounted on the floor in the left diagonal front of the driver in the cab. The traveling vehicle can execute auxiliary brake by the energy consumed by the engine. When driving down the long slope, the driver must use exhaust brake. In ice and snow or mud road, the exhaust brake can be used to reduce sideslip. When the vehicle meets other cars or passes through the bad road, the exhaust brake can be used for reducing the speed in advance.
  • Through the usage of exhaust brake, the usage frequency of master brake, abrasion and heat of tires and wheels can be reduced and it is in favor of extending the service life, reducing the fuel consumption and improving the safety of traveling.

Precautions for the application of exhaust brake:

  • The engine revolution speed shall not be greater than 2000 r/m.
  • When the transmission is in low gear, the efficiency of the exhaust brake is high.
  • The vehicle is not allowed to travel in neutral gear for there is no auxiliary brake effect when traveling in neutral gear.
  • Pressing the clutch or the accelerator pedal will cause the exhaust brake to fail or exit the operation, which may affect driving. Please be careful..
  • In rain, sneeu, slippery and other bad road conditions, exhaust brakes should be used with caution to avoid accidents such as side slipping and tail flick

3. Emergency and parking brake

  • The manual brake can also be used as emergency brake or parking brake. It achieves its function by the energy storage spring brake cylinder of the rear axle (or double rear axles). The functions of parking brake are achieved by operating the manual brake valve handle. When the brake system has any fault, the emergency brake can be automatically achieved by the push effects of the energy storage spring.
  • The spring brake can be released only if the pressure of brake system reaches 0.55MPa (5.5 bars) and the manual brake signal light goes out.

Notice:

Prior to starting the engine, the manual brake valve handle must be in the brake position, or the effects of parking brake will eliminate after the pressure of brake system pressure increases.

Working Principle Of Shacman Truck Brake System

  • The working principle of the braking system is the key to ensure that the vehicle can safely decelerate and stop during traveling. Its working principle involves the transmission of driving braking force, conversion and regulation of braking force.
  • First, the braking system is activated when the driver depresses the brake pedal. In a hydraulic brake system, this causes the brake master cylinder to compress the brake fluid and transfer the high-pressure brake fluid to the various braking devices, such as brake discs or drums; whereas in a pneumatic brake system, the operation of the brake pedal causes the brake master cylinder to compress the air and transfer the high-pressure gas to the various braking devices.
  • Secondly, braking force is converted into friction by the friction between the brake disc and the brake pad or the brake drum and the brake shoe. When the brake disc rubs against the brake pads or the brake drum rubs against the brake shoes, the friction generated causes the wheels to slow down, thereby slowing and stopping the vehicle.
  • The braking system also ensures braking effectiveness in different situations by adjusting the amount and distribution of braking force. By adjusting the force of the brake pedal or the distribution of pressure between the brakes, the braking force can be adjusted to suit different road conditions, vehicle speeds and loads.
  • The braking system will work differently in different situations. Byvoorbeeld, at high speeds, more braking power is needed to achieve rapid deceleration; while at downhill driving, more precise braking control is needed to avoid over-braking leading to loss of vehicle control.

Maintenance and upkeep Of Shacman Truck Brake System

  1. Check Brake Fluid Level Regularly: Brake fluid level should be checked regularly and made sure that it is within the proper markings. If the brake fluid level is too low, it may affect the normal operation of the braking system, so you need to add brake fluid in time.
  2. Check brake pad wear: Brake pads are wearing parts in the braking system, and their wear directly affects the braking effect. Regularly check the thickness and degree of wear of the brake pads, if you find that the brake pads are badly worn, you should replace them in time to ensure the braking effect.
  3. Check the brake system for oil leakage: Oil leakage is one of the common problems of the brake system, which may lead to weakened braking effect or even failure. Regularly check whether there are oil leaks in various parts of the braking system, such as the brake master cylinder, brake lines and braking devices, ens., and repair the oil leaks in time.
  4. Clean the brake system: The brake system will accumulate dust, dirt and metal shavings and other impurities during use, which will affect the braking effect and life. Regular cleaning of the braking system, including brake discs, brake drums, brake master cylinder and brake pads, ens., to keep them clean, will help extend the service life of the braking system.
  5. Pay attention to abnormal phenomena of the braking system: In daily driving, if you find abnormal phenomena such as abnormal feeling of the brake pedal, insufficient braking force, abnormal sound when braking or the brake system light is on, you should stop the car immediately for inspection and carry out maintenance or replacement of the faulty parts in time.
  6. Regular Brake System Maintenance: In addition to routine maintenance, it is also very important to perform regular brake system maintenance. It is recommended that regular maintenance be carried out in accordance with the maintenance manual provided by the vehicle manufacturer, including replacing the brake fluid, checking the performance of the braking system and adjusting the braking device.
