natnoy road, general view.

In the traveling track, inductors 1 of a linear asynchronous motor are installed in series on the upper stage. The cabin 2 of the passenger cableway cabin, equipped with supporting rollers 3, has a floor 5 mounted on the springs 4. A rotor 6 of a linear asynchronous motor is rigidly connected to the floor 5. A hydraulic damper 7 is installed in the cab under the floor 5 jQ, the rod 8 of which is rigidly connected to the floor 5. The damper 7 is equipped with a valve 9 controlled by an electromagnet 10. The electromagnet is powered from the pressure contacts 11 through the contact 12 of the control element for opening the cabin doors.

When the cabin enters the acceleration section, the cabin doors are closed, the contact is open, 12 is open, and the electromagnet 10 is de-energized. At the landing area, the doors are opened, the door contact 12 is closed, and through the pressure contacts 11, the electromagnet 10 receives a pit 25

acceleration of the cab according to a given law. With an increase in load, the air gap decreases and at the same current, the inductor, the tractive force automatically increases and as a result the cab accelerates as in the previous case.

When the doors are closed, the door contact is disconnected, the electromagnet de-energizes and the damper valve closes, and the rotor becomes stationary.

Thus, having programmed in advance the acceleration process for one state (load value) of the cabin, then due to the automatic change of the air gap between the inductor and the rotor depending on the load and, consequently, the automatic change of tractive effort, the acceleration process will be the same same program.

Invention Formula This opens the damper valve 9 and brings it to working condition. The damper 7 is designed to prevent the cab floor 5 from oscillating during loading and maintain its rigidity after loading. Rotor 6 linear motor, lean on. the springs 4 and on the rod 8 of the damper 7 can freely mix depending on the load. When the air gap changes between the inductor 1 and the rotor 6 within a certain range; with the same inductor current, the thrust force of the engine automatically changes within fifty percent. 35 40 An accelerating device of a passenger cableway containing a linear asynchronous engine, the inductors of which are located in the track, and the rotor is rigidly connected to the floor of the passenger cabin, spring-loaded relative to its hull, characterized in that, in order to increase reliability by fixing the working gap, it is equipped with cont45 I roll open cab doors} installed in the passenger cabin between the floor and the body with a hydraulic damper, the rod of which is rigidly connected to the floor, and the body with the body of the cabin, and the hydraulic damper is previously known for this linear valve with a controlled valve chain the stroke, depending on the load, corresponded to the required clearance (i.e., the gap is established according to this law). If the load on the cabin floor is minimal (the cabin is empty), the air gap between the inductor and the rotor is maximum and, consequently, the pulling force acting on the cabin is acceleration of the cab according to a given law. With an increase in load, the air gap decreases and at the same current, the inductor, the tractive force automatically increases and as a result the cab accelerates as in the previous case. When the doors are closed, the door contact is disconnected, the electromagnet de-energizes and the damper valve closes, and the rotor becomes stationary.
