The YPE11 stacked electric hydraulic arm disc brake is a new type of brake developed and designed based on the YP arm disc brake. It uses an Ed electric hydraulic thruster as the driving device.

The brake is equipped with a first and second stage brake spring mechanism, which is controlled by an electromagnetic controller to generate two-stage braking forces of different sizes and apply them step by step to the brake disc, achieving superimposed braking (also known as two-step braking).

Users can adjust the size of the two-stage braking torque separately according to their usage requirements.

During the normal operation of the equipment, a smaller first level braking torque is used to prevent large impacts during braking and achieve smooth, non shaking deceleration and parking; When encountering sudden gusts of wind or when equipment stops working and needs to be parked, an additional braking torque is added to the original small braking torque to form a larger braking torque that acts on the brake disc together, achieving windproof or parking braking.

The working condition requirement of “small braking torque required for deceleration braking during equipment operation, and large braking torque required for parking braking or windproof braking” has been achieved on a single brake.

основные характеристики

• The main swing hinge points of the brake frame are equipped with self-lubricating DU shaft sleeves, which have high transmission efficiency, flexible and reliable action, long service life, and do not require lubrication during use;
• The brake pad adopts a key connection plug-in structure, bolted connection, easy and fast installation and replacement. The friction material adopts asbestos free mixed fiber friction material (NAO), with stable friction coefficient and good environmental applicability;
• 1、 The two levels of braking torque can be adjusted separately, and the two levels of braking springs are arranged in their respective square tubes. The outer walls on both sides are equipped with their own braking torque scales, making it easy to adjust and read the braking torque; The first level braking torque can be precisely adjusted within the range of 20NM to the rated torque.
• The driving device adopts Ed electric hydraulic thruster, with a fully sealed single push rod structure, high-pressure cast aluminum alloy shell, non oil immersed motor, and F-class insulation; IP54 protection level; The seals and bearings are made of internationally renowned brands, with excellent performance and long service life;
• All non primary load-bearing bolt connections are made of stainless steel, and the pin shafts are treated with hard chrome plating or made of stainless steel material, with good anti-corrosion performance;
• The brake pad is equipped with an interlocking equal clearance device, which can ensure equal clearance of the brake pads on both sides; The brake pad is equipped with an automatic pad positioning device, which can completely avoid the phenomenon of brake pads floating on the brake disc;
• The brake is equipped with an automatic compensation adjustment device, which keeps the brake pad clearance and braking torque constant during use, eliminating the need for frequent adjustments.
• The brake is equipped with a manual opening device as standard, which can manually release (open) the brake.
• The brake is equipped with an open position detection switch function as standard, which facilitates automatic online control. In addition, it also provides the optional function of brake pad wear limit position detection switch, which users can choose according to their working conditions.
• Using a low-power electromagnetic controller to control the second level braking torque, it can achieve one-step deceleration braking and two-step combined safe windproof braking according to user operating conditions. The delay time for the second step of braking can be set according to the operating conditions, with a wide adjustment range (0.05S-100h) and good synchronization for multiple units to control simultaneously.
