SU850456A1 - Traction device for monorail vehicle - Google Patents

Description

The invention relates to mechanical engineering, in particular to monorail locomotives.

A mono-rail vehicle traction device is known, comprising a rigid frame, in which rollers covering the monorail are kinematically connected to the push mechanism and to drive their rotation (1), which are mounted on horizontal axes.

A disadvantage of the known device is its low reliability.

The purpose of the invention is to increase the reliability of the device. fifteen

This goal is achieved in that the push mechanism is made in the form of a non-self-braking screw pair, the screw of which is directed along the line of action of the pressure force, and the nut is 20 Nematically connected to the specified drive.

The drawing shows the proposed device.

The device comprises a frame 1, on which a motion drive is installed, including a drive shaft 2, gears 3 and 4, non-self-locking screw pair 5 and b, gears 7 and 8, shaft 9, rollers 10 and 11, spring 12, fork 13, 30 ' The device is located on a monorail (not shown).

The device works like this.

The spring 12 through the spline shaft 6 installed in the thrust bearings presses the fork 13 and provides a minimum pressure force of the roller 10 to the monorail. When the WADA 2 rotates through gears 3 and 4, the spline screw nut 5 receives rotation. The splined shaft rotates and through the gears 7 and 8 transmits the rotation to the shaft 9, on which the drive roller 10 is fixed. The device moves along the monorail in accordance with the set speed.

An increase in the load causes an increase in the transmitted torque in the rotary motion drive, in which a non-self-braking slotted screw drive is installed. The pet redach is located in the direction of action of the pressing force of the roller 10 to the monorail. As a result, it increases (the axial force in the helical gears 5 and 6 and the magnitude of the pressing force, providing improved frictional adhesion of the drive roller 10 with the monorail.

The proposed device improves the traction characteristics of the drive while reducing wear of the chassis, since the pressing force increases only with increasing load in the drive movement. In addition, there is an automatic control of the pressing force of the roller 10 to the monorail in the traction function.

The device can be widely used in the monorail trans-.θ sports drive.

holding a rigid frame, in which rollers covering the monorail are fixed on horizontal axes kinematically connected to the pressure mechanism and their rotation drive, characterized in that, in order to increase reliability, the pressure mechanism is made in the form of a non-self-locking screw pair, the screw of which is directed along the line action of the pressing force, and the nut is kinematically connected with the specified drive.

(54) TRAFFIC DEVICE FOR MONORAL VEHICLE The invention relates to mechanical engineering, in particular, to monorail locomotives. A monorail vehicle traction device is known, comprising a rigid frame in which monorail rollers are fixed on horizontal axes, kinematically connected with the pressure mechanism and with their rotation drive C. A disadvantage of the known device is low reliability. The purpose of the invention is to increase the reliability of the device. The goal is achieved by the fact that the pressure mechanism is made in the form of a non-braking screw pair, the screw of which is directed along the line of action of the thrust force, and the nut is connected mathematically with the specified gear. The drawing shows the proposed device. The device contains a frame 1, and the movement drive is installed, including the drive shaft 2, gears 3 and 4, non-braking screw pair 5 and 6, gears 7 and 8, shaft 9, rollers 10 and 11, spring 12, fork 13, the device is located on a monorail (not shown). The device works like this. The spring 12 through the splined shaft 6 installed in the thrust bearings presses the plug 13 and provides the minimum force of the roller 10 against the monorail. When rotating vgsha 2 through gears 3 and 4, nut 5 of the splined screw gears receives rotation. The spline shaft rotates and, through gears 7 and 8, transmits rotation to the shaft 9, on which the driving roller 10 is attached. The device moves along a monorail in accordance with a given speed. An increase in the load causes an increase in the transmitted torque MOMei ment in the drive of the rotational motion, in which the spindle-screw spindle gearbox is installed. Peg redacha is located in the direction of the action of pressing the roller 10 to the monorail. As a result, the iOce force increases in screw gears 5 and 6 and the magnitude of the exaggerated effort, providing an improved improvement of the friction coupling of the driving roller 10 with the myo-rail ... The proposed device improves the traction characteristic of the drive while reducing wear on the undercarriage, since the thrust force only increases with increasing load on the drive train. In addition, there is an automatic control of the pressing force of the roller 10 to the monorail in the function of pulling force. The device can find a wide application in the drive of a monorail tran sport. Claim device for a monorail vehicle containing a rigid frame in which are mounted on horizontal axes covering monorail rollers kinematically associated with a pressure mechanism and a drive for their rotation, characterized in that, to increase reliability, the pressure mechanism is made the form of a non-braking screw pair, the screw of which is directed along the line of action of the pressing force, and the nut is kinematically connected with the specified drive.
