German BEN Buchele Elektromotor brake, BEN Buchele Elektromotor model, BEN Buchele Elektromotor price

BEN Buchele Elektromotor brake is the actuating component in the entire braking system. The electromagnetic brake is installed on the trailer wheels. Its structure is shown in Figure 1. The entire brake mainly consists of components such as the electromagnet, lever drive mechanism, front and rear brake shoes, base plate, and friction ring. It is a mechanical part that stops or decelerates moving parts in machinery. Commonly known as a brake. The brake mainly consists of a brake frame, braking elements, and operating devices. Some brakes are also equipped with automatic adjustment devices for braking element clearance. To reduce braking torque and structural dimensions, brakes are usually installed on the high-speed shaft of the equipment, but for large equipment with high safety requirements (such as mine hoists, elevators, etc.), they should be installed on the low-speed shaft close to the working part of the equipment.

BEN Buchele Elektromotor brake classification

Classified by braking energy source, service braking systems can be divided into: braking systems that use the driver's physical effort as the sole braking energy source are called manual braking systems; those that rely entirely on potential energy in pneumatic or hydraulic form converted from engine power are called power braking systems, where the braking source can be an engine-driven air compressor or oil pump; braking systems that use both manual effort and engine power are called servo braking systems. Parking braking systems can be manual or power-assisted. There are also inertia braking systems and gravity braking systems specifically for trailers. According to the transmission method of braking energy, braking systems can be divided into mechanical, hydraulic, pneumatic, and electromagnetic types. Braking systems that simultaneously adopt two or more energy transmission methods can be called combined braking systems.

BEN Buchele Elektromotor brake mechanism

Depending on the installation position on the vehicle, parking brake devices are divided into central parking brake devices and wheel parking brake devices. The former's brake is installed on the propeller shaft and is called a central brake; the latter shares a set of brakes with the service braking device, featuring a simple and compact structure, and has been widely applied 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 serves as the brake disc for the disc brake, while the central drum section serves as the brake drum for the drum brake. When applying 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 the flat-head pin. Its intermediate pivot pushes the brake push rod to the left, pushing the front brake shoe against the brake drum. After the front brake shoe presses against the brake drum, the push rod 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, push the parking brake lever back to the non-braking position. The brake lever returns to its original position under the action of the return spring wound on the cable, while the return springs of the brake shoes pull the two brake shoes together.

BEN Buchele Elektromotor brake hydraulic device

Passenger car service braking 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 cylinders in the front wheel caliper 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. There are various pipe fittings between hydraulic components and between 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 can continue to increase until full braking is achieved only after the brake clearance is eliminated and braking torque begins to be generated. During this process, due to the elastic expansion deformation of the oil pipes under hydraulic pressure and the elastic compression deformation of the friction elements, the pedal and wheel cylinder pistons can continue to move a certain distance. When the pedal is released, the brake shoes and wheel cylinder pistons return to their original positions under the action of return springs, forcing the brake fluid back into the master cylinder.
