Brake Booster Market - Freescale Semiconductor

PERFOMANCE BOOST The Freescale* MPXV4115V pressure sensor is the ideal part for automotive vacuum sensing needs such as those found in the brake booster application. Prepared by Marc Osajda Automotive Sensor Marketing Motorola – Toulouse, France Advanced braking systems are becoming increasingly common in today’s automobiles. Higher level systems and technology now being used in “brake assist systems” (BAS) in several European cars, have made it possible for more efficient and intelligent braking systems. A key functional application block found in these braking systems that has advanced with this technology surge, is the vacuum brake booster function. Here are a few driving factors behind the need and use of the brake booster, which helps ensure a safer braking system. Independent Systems: In current gasoline engine cars, the engine’s intake manifold generates the vacuum for the brake booster. This system works fine with one exception. The amount of vacuum in the brake booster is unknown by the braking system. Thus the amount of amplification is also unknown. If heavy braking is needed, there is no possibility for the brake system to interact with the intake manifold if additional amplification is required. The manufacturer’s interest for having the vacuum generated by an auxiliary vacuum pump is that the brake system can manage the amount of vacuum as required, on demand. This in turns gives it the ability to perform amplification on its own, giving it complete independent from the engine’s operating condition. The auxiliary pump is also able to provide higher amounts of vacuum whenever necessary. In situations calling for heavy braking, the pressure will naturally decrease in the brake booster, also causing a decrease in the amplification during braking. With an external pump it is possible to maintain, or even increase the amplification during a heavy braking phase. Smart Safety: Wheel blocking due to high-braking force is controlled by the Anti-Lock Brake System (ABS). However, it has been observed that in many cases, drivers do not...

Vacuum Brake Booster Testing and Diagnosis.pdf

Vacuum Brake Booster Testing and Diagnosis Vacuum Brake Booster Testing and Diagnosis This procedure will require the use of a hand operated vacuum pump with a vacuum gauge. If you do not own one it can often be rented or borrowed from most “big box” parts stores. (Note: 18”HG is the minimum engine vacuum at idle in gear to effectively operate a vacuum booster 1) Remove vacuum hose from check valve on booster. Place hose from vacuum pump onto check valve and draw booster to 20” of vacuum. 2) Let booster sit with vacuum applied for 5 minutes. If vacuum does not stay steady at 20” it is faulty and needs to be replaced. If vacuum does hold steady at 20” proceed to step 3. 3) With 20” of vacuum in booster depress brake pedal once and release it. The booster should transfer some but not the entire vacuum in reserve. Depending on how hard the pedal is depressed it is normal to see 5-10” of vacuum depleted from reserve. The most important thing is to ensure the booster does transfer vacuum but does NOT transfer the entire vacuum in its reserve. If vacuum remains at 20” OR goes to zero the booster is bad and will need to be replaced. If vacuum transfer is within the above parameter proceed to step 4. 4) Once again draw booster down to 20” of vacuum. Go inside car and depress brake pedal and hold down for 30 seconds. You should see the gauge drop slightly and then hold steady. Vacuum should stay steady as long as you are holding the pedal down. If vacuum drops while pedal is being held down the booster is faulty and will need to be replaced.

The ATE T50 Brake Booster - 190SL | 190 SL

Fifty percent less pedal force I n most of the models of the 1950s and 1960s, Mercedes-Benz provided a power brake booster manufactured by ATE. The booster does not pro- vide additional braking capacity, a common misconception, but rather reduces the pedal force required for braking. The power brake is a vacuum-assisted hydraulic component using the pressure difference between engine intake manifold vacuum and atmospheric pressure for its operation. The power unit increases the pressure created physically in the brake master cylinder so that the same braking effect can be produced with less pedal effort. With a brake booster installed, the pedal force required for braking is reduced by 50 percent. The ATE T50 Brake Booster uses vacuum to “boost” the hydraulic brakeline pressure. The booster contains a hydraulic cylinder, a large vacuum piston that presses against the hydraulic cylinder, and a control circuit that regulates the vacuum flow based on brake-line pressures. This technology had been well proven since the early 1900s, and the T50 has been exceptionally reliable over many years of use. The Booster in action The power booster is a very simple design requiring only a vacuum source to operate. In gasoline-engine cars, the engine provides a vacuum suitable for the boosters. Because diesel engines do not produce a vacuum, dieselpowered vehicles must use a separate vacuum pump. A vacuum hose from the intake manifold on the engine pulls air from both sides of the diaphragm when the engine is running. When the driver steps on the brake pedal, the input rod assembly in the booster moves forward, blocking off the vacuum port to the backside of the diaphragm and opening an atmospheric port that allows air to enter the back chamber. Suddenly, the diaphragm has vacuum pulling against one side and air pressure pushing on the other. The result is forward pressure that assists in pushing the input rod, which in turn pushes the piston in the master cylinder. The amount of power assist that’s provided by the booster depends on the size of the diaphragm and the amount of intake manifold vacuum produced by the engine. A larger diaphragm will increase the boost.

Introduction to Brake Systems – Study Guide

Introduction Everybody knows that when you press your foot on the brake pedal the vehicle is supposed to stop. But how does the pressure from your foot get to the wheels with enough force to stop a heavy vehicle? In the following sections, we will study the systems and components required to allow brakes to work effectively. Course Objectives Upon completion of this course, technicians should understand and be able to apply their knowledge of: • • • • • • • • • • • • Brake functions and components Split hydraulic systems Master cylinder operations Balance control systems Power brake booster systems Disc brake operation Micrometer reading Drum brake operation Brake fluids Brake bleeding operations Brake lines and hoses Basic diagnosis Using the Job Sheets As you proceed through the online module, on some pages you will find links that will open a window with a printable procedure or job sheet containing hands-on lab activities based on the NATEF standards related to the content you are studying. When you come upon a procedure or job sheet link, click on it and print the job sheet for completion in the shop. See your instructor for guidance in completing the job sheets. Some jobs sheets will require supplemental materials such as a vehicle service manual, equipment manual, or other references. Brake System Functions Automotive brakes are designed to slow and stop a vehicle by transforming kinetic (motion) energy into heat energy. As the brake linings contact the drums/rotors they create friction which produces the heat energy. The intensity of the heat is proportional to the vehicle speed, the weight of the vehicle, and the quickness of the stop. Faster speeds, heavier vehicles, and quicker stops equal more heat. Automotive brake systems can be broken down into several different sub-systems (fig. 1): • Apply system • Boost system • Hydraulic system • Wheel brakes • Balance control system • Warning system (fig. 1) Base Brake Systems .

HYDRAULICS & BRAKE BOOSTER CATALOG - Aisin

The clutch master cylinder is a device that transforms mechanical force into hydraulic pressure. As the driver presses the clutch pedal, the pedal lever applies force to the clutch master cylinder which transmits hydraulic pressure to the clutch release (slave) cylinder that disconnects engine power to the transmission. Structure and Components [Conventional Type] Inlet Union Oil Spill Hole Aluminum Body Flare Nut Pipe Joint Boot Spring Primary Cup Resin Piston Push Rod Rel Secondary Cup Spring Metallic Clevis Damper Stud Bolt The clutch master cylinder structure consists of the piston, cups, and springs, built within a precision machined body. The primary cup, positioned on the leading side of the body, functions to create hydraulic pressure when fluid is forced inside by the piston. Located on the trailing side is the secondary cup, which guides the piston and prevents fluid from leaking. When the clutch pedal is pressed, the primary cup is blocked away by the piston from the oil spill port leading to the reservoir tank, pressure in the cylinder rises as the fluid is fed through the pipeline. When the clutch pedal is released, the hydraulic pressure and the force of the return spring pulls back the piston to relieve fluid back into the reservoir. The clutch master cylinder is what provides the necessary force to control the application of drivetrain power. 2 Clutch Master Cylinder Variations Clutch Master Cylinder Variations Conventional Port-less Type Stand Alone / Integrated Reservoir Type Types With and Without Stud Bolts Types With and Without Clevis Damper Types With and Without Clutch Booster ...
