METHOD AND ELEVATOR DRIVE WITH A BRAKE DEVICE

In this elevator drive with a brake device (1), compression springs (2, 3) act on brake levers, whereby brake linings (13, 16) generate a brake force on a brake drum (14). The more the brake linings (13, 16) wear due to abrasion, the smaller the distance (d) of the plunger (21) from the brake magnet housing (19) becomes. Should the plunger (21) come into contact with the brake magnet housing, the braking capacity of the brake linings (13, 16) is completely eliminated. So that this operating condition that is dangerous for elevator users cannot occur, a switch (27) is provided that detects a minimum distance (d). The switch (27) can be arranged on the plunger (21) of the brake magnet (4) and detect the minimum distance (d) to the brake magnet housing (19) or, in the case of a retrofit, the switch (27) can be arranged on the brake magnet rod (23) and, for example, detect the distance of the second joint (24) from the brake magnet housing (19), and at the minimum distance (d) the switch (27) switches.

Apparatus for adjusting brake force for passenger conveyor emergency brake

Emergency brake assembly for use in passenger conveyor system e.g. escalator or moving walkway The emergency brake is provided with a brake force adjustment assembly. The assembly supplies a braking force that is proportional to the passenger load imposed on the main drive motor of the conveyor at any point in time. Thus, if the conveyor is lightly or heavily loaded with passengers, the emergency brake force will be automatically proportionally decreased or increased. In the event of an emergency stop condition, the braking force applied to the drive sprocket axle will be sufficient to stop movement of the conveyor within the predetermined time period that is preprogrammed into the conveyor controller.

Brake

This torque-measuring device for a brake is based on the principle of measurement of the elastic deformation of active parts of a brake. The principle according to the invention is illustrated and explained with the example of a shoe brake. In that case, regions (23, 24) with a reduced bending moment resistance are formed at the brake levers (2, 3) and elastically deform under the action of torque. The elastic deformation is detected by means of strain gauge strips (R1 to R4) arranged in these regions (23, 24) and connected as a measuring bridge and the obtained voltage signals are conducted on to the lift control for the purpose of processing into reference signals (28). By these reference signals a motor torque compensating for the measured torque is generated in the drive motor by way of the drive control before the release of the brake and the thus resulting torque at the brake shaft is brought to zero. A jerk-free setting off, without a torque jump, results therefrom after release of the brake.

Winch having automatic brake

An automatic brake for vehicle winch that is automatically applied when the applied torque of the drive motor ceases and automatically released upon application of motor torque. The brake features brake pad segments that move radially outward against the interior of the drum to affect braking and retract radially inward to affect releasing of the brake. The pads have tapered ends that mate with opposed frusto-conical shoes. The brake utilizes rotation of a cam rotatable with respect to a cam follower in one direction to force one shoe toward the other to force the pads radially outward to engage the interior surface of the drum. Rotation of the cam with respect to the cam follower in the opposite direction releases the braking action. A wave spring is incorporated to eliminate chatter as the brake is applied and released. The configuration of the brake components provides a conductive path for the dissipation of heat generated by the braking action.

Double shoe brake for hoists or lifts - has ratchet type external adjuster with greater travel than automatic adjustment mechanism

There is a brake lever pivoting on the base plate and brake shoes connected to the lever and operating against a drum by an air operated brake pressure spring. An automatic adjustment mechanism compensates for lining wear. The adjustment of the air port is kept constant within a narrow tolerance range when the lining is fully worn without hindering the operation of the adjuster. Each adjusting screw (3) is operated by a direction dependent coupling (ratchet mechanism or free wheel). The operating distance of this coupling is longer than the operating distance of the automatic wear adjustment mechanism.
