Problems solved by technology
[0003] With the continuous improvement of elevator safety requirements, when many electromagnetic brakes change from the braking state to the suction state, a larger electromagnetic brake is required due to the greater positive pressure. The attractive force pulls the armature back, which is accompanied by a large pull-back vibration and noise. Long-term vibration will have a negative impact on all parts of the brake.

Embodiment Construction
[0013] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0014] Such as figure 1 In the shown brake damping device, the brake 1 is arranged on both sides of the friction disc of the elevator traction machine.
[0015] The brake 1 generally mainly includes a yoke 2 , an armature 3 , a tongue plate 4 arranged on the armature 3 and a friction plate 5 arranged on the tongue plate 4 , and the yoke 2 and the armature 3 are movably connected as a whole by bolts 6 . The yoke 2 and the armature 3 are arranged in parallel with a gap, and the yoke 2 is provided with an annular groove 7 , and a coil 8 is sleeved in the annular groove 7 .
[0016] At least one shock absorber 9 is arranged inside the yoke 2. In this embodiment, there are four shock absorbers 9. The shock absorber 9 extends out of the yoke 2 and contacts the armature 3. At the same time, each shock absorber 9 are connected with an adjustment device, th...

The invention relates to a shock absorption device for brakes. The brakes are arranged on two sides of a friction disk of an elevator tractor and respectively comprise a magnetic yoke, an armature, a tongue plate and a friction plate, wherein the tongue plate is arranged on the armature, and the friction plate is arranged on the tongue plate. A gap is reserved between the magnetic yoke and the armature which are parallelly arranged, an annular groove is arranged on the magnetic yoke, and a coil is sleeved in the annular groove. When the coil is powered on, the magnetic yoke can suck the armature, and the friction plate is separated from the friction disk. When the coil is powered off, the magnetic yoke releases the armature, and the friction plate is attached to the friction disk. At least one shock absorption pad is arranged in the magnetic yoke, extends out of the magnetic yoke and contacts with the armature. Shock or noise generated when the armature is pulled back by electromagnetic attraction is relieved or reduced by the aid of the shock absorption pads, the shock absorption device is simple in structure and effective in shock absorption, and the service lives of components of the brakes can be effectively prolonged.
Description
technical field [0001] The invention relates to an elevator traction machine brake, in particular to a brake damping device. Background technique [0002] The brake is an important safety device of the elevator, and its safety and reliability are one of the important factors to ensure the safe operation of the elevator. Electromagnetic brakes usually use a built-in coil winding, which generates or loses electromagnetic force to generate action through the energization or de-energization of the coil winding. [0003] With the continuous improvement of the safety requirements of elevators, when many electromagnetic brakes change from the braking state to the suction state, due to the large positive pressure, a greater electromagnetic attraction force is required to pull the armature back, which is accompanied by a larger force. Pull back the vibration and noise, long-term vibration will have a bad effect on all parts of the brake. Contents of the invention [0004] The obj...
