German GKN Stromag brakes, GKN Stromag models, GKN Stromag prices

GKN Stromag brakes, also known as disc brakes, pneumatic brakes, air-operated disc brakes, and air-hydraulic pneumatic brakes, are a type of industrial drive brake. They are actuators that use air pressure to stop or decelerate moving parts in machinery. The structure is simple, installation is convenient, and they are durable, resistant to pressure, drops, and impacts, with a long service life. Generally, only the brake pads need to be replaced, which is easy and convenient. They utilize magnetic effects.

GKN Stromag brake classification

Classification by braking energy source: Service brake systems are categorized as follows: brake systems that rely solely on the driver's physical effort as the braking energy source are called manual brake systems; those that rely entirely on potential energy in the form of air pressure or hydraulic pressure converted from engine power are called power brake systems, where the braking source can be an engine-driven air compressor or oil pump; brake systems that combine human effort and engine power are called servo brake systems. Parking brake systems can be manual or power-assisted. Inertia brake systems and gravity brake systems are specifically used for trailers. According to the transmission method of braking energy, brake systems can be divided into mechanical, hydraulic, pneumatic, and electromagnetic types. Brake systems employing more than one energy transmission method simultaneously are called combined brake systems.

GKN Stromag brake mechanism

Based on different installation positions in vehicles, parking brake devices are divided into central parking brake devices and wheel parking brake devices. The former has its brake installed on the driveshaft and is called a central brake; the latter shares a set of brakes with the service brake system, featuring a simple and compact structure, and is widely used in passenger cars. This type of brake combines a disc brake serving as the service brake and a drum brake serving as the parking brake. The outer rim of the dual-action brake disc acts as the disc for the disc brake, while the inner drum section acts as the drum for the drum brake. To apply the parking brake, pull the manual parking brake lever in the cab to the braking position. Through a series of levers and cables, the lower end of the parking brake lever is pulled forward, causing it to rotate around a flat-head pin. Its intermediate pivot pushes the brake pushrod to the left, pressing the front brake shoe against the brake drum. Once the front brake shoe presses against the brake drum, the pushrod stops moving, and the brake lever continues to rotate around the intermediate pivot. Consequently, the upper end of the brake lever moves to the right, pressing the rear brake shoe against the brake drum to apply the parking brake. To release the brake, return the parking brake lever to the non-braking position. The brake lever returns under the action of the cable return spring, and the brake shoe return springs pull the two brake shoes back.

GKN Stromag brake hydraulic system

Passenger car service brake systems all adopt hydraulic transmission devices, mainly consisting of the master cylinder (main brake cylinder), hydraulic lines, wheel cylinders (slave cylinders) in the rear wheel drum brakes, and hydraulic calipers in the front wheel disc brakes, as shown in the figure on the right. In addition to metal pipes (copper pipes), specially made rubber brake hoses are used for the connecting oil pipes between the master cylinder and wheel cylinders. Various pipe fittings are used between hydraulic components and sections of oil pipes. Before braking, the hydraulic system is filled with specially formulated brake fluid. When the brake pedal 4 is pressed, the master cylinder 5 forces brake fluid into the wheel cylinders 6 and brake calipers 2, pushing the brake blocks against the brake drums and discs. The hydraulic pressure and pedal force continue to increase until full braking is achieved, starting when the brake clearance disappears and braking torque begins to generate. During this process, due to elastic expansion deformation of the oil pipes under hydraulic pressure and elastic compression deformation of friction elements, the pedal and wheel cylinder pistons can continue to move a certain distance. Releasing the pedal allows the brake shoes and wheel cylinder pistons to return to their original positions under the action of return springs, forcing the brake fluid back into the master cylinder.
