The flexible flat clothings, manufactured with utmost accuracy substantially influence the carding quality. Burr-free flat clothings, ground straight with utmost precision are imperative to achieve best possible carding results. For this reason, GRAF has developed the flat-grinding machine DSM 20 and DSM 20/1, which allows for all spinning mills to grind and resharpen the flat-tops economically and efficiently with the precision required. Number of strokes of slides 50 / min Gear motor rating 0,18 kW Weight DSM 20 420 kg ● Precisely straight flat clothings following initial equalising (entire set within a height tolerance of 0,05 mm or less) ● There is the choice to have the DSM 20 or DSM 20/1 grinding roller equipped with either ceramic grinding rings or else an emery grinding fillet ● We recommend the ceramic grinding roller for the initial equalising provided the subsequent resharpening is carried out with a DSW on the card ● The ceramic grinding roller allows the socalled heel grinding, i.e. significantly less abrasion of the tooth points at the time of initial equalising leading to extended life time ● In cases where the resharpening of the flat clothings on the card is not possible we recommend the DSM 20 and DSM 20/1 to be equipped with the emery fillet grinding roller

ZE15A Gear Grinding Machine for economical hard gear finishing of ...

In recent years the demands for precision machining of gears in automobile transmissions, for low noise and vibrations, has been ever increasing. Historically, conventional finish machining of gears was a pre-heat treatment operation typically by shaving. However, the requirement for higher precision forced a shift toward a post heat treatment operation using a generating process, which eliminates thermal distortion, thus enabling high quality and precision. The Mitsubishi ZE15A gear-grinding machine was duly developed for the high production line applications and launched into a domestic market typically dominated by European machines. (3) Ease of use for the user achieved via interactive dialog functions and full CNC control of all axes. This paper describes the principle of grinding and control for the ZE15A before presenting some machining examples.

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 ...
