Description

The invention relates to devices for adjusting the tension of flexible le. Meters (e.g., cables, cables), us. mounted on the vehicle.

Basically auth.St. No. 553202 describes a device comprising a drum mounted on a vehicle, a receiving unit and a device for adjusting the tension of a flexible element, which consists of a strut mounted on the vehicle and made with a sleeve in which an axle is hinged. The balancer is composed of a rocker and two blocks of the rocker located at the ends of the rocker arm.

In the center, the yoke is integral with a disk cam on which the tape is rigidly fixed, connected to a spring block consisting of a tension spring, plugs and hinged bolts that are hinged on the one side with the tape, and on the other side with bracket 8 rigidly mounted on the rack. A limiter is fixed on the beam, and a limit switch and a ynop are mounted on the rack.

However, such a device is designed to work with flexible elements that allow the same tension force and are not predictable to ensure the constant tension of the flexible elements of different types of ooBsC with different allowable tension forces.

The aim of the invention is to expand the range of generated tension forces,

This device is equipped with an additional spring block, and an additional cam mounted on the rack sleeve can be pseorot made with a hole and interconnected by means of a tape with an additional spring block, while a clamp fixed on the balancer axis is fixed to the movable rod entering into additional cam hole.

On the vehicle 1, (FNG. 1), a device 2 is attached to adjust the tension of the flexible aneMetira 3, the drum 4 and the receiving unit 5. The device 2 is used to adjust the tension of the flexible element 3 coC | Tta1t from the stand 6, made with the sleeve 7 ( Fig. 3), 1 in which axis 8 is installed. Axis 8 is made with equestrian 9 and elongated end 10. At end 9 of axis 8, a balance bar I is attached, consisting of a rocker arm 12 and two blocks 13 guiding the flexible element 3 Blocks 13 are located at the ends of the yoke 12. In the center, the yoke 12 is made integral with the cam 14, on which it is rigidly fixed The penta 15 is connected to the spring block 16. The spring block 16 consists of an extension spring 17, which is equipped with plugs 18 and hinged bolts 19 at the ends, which are hinged on one side with tape 1 and on the other side with bracket 20, rigidly mounted on the rack 6. On the yoke 12 rigidly fixed stop 21, and on the rack 6 mounted limit switch 22 and the stop 23. At the other end 10 of the axis 8 fixed clamp 24 with a stem 25, Additional cam 26 with a hole 27 hinged on the sleeve 7 axes 8. On the cam 26 is rigidly fixed A tape 28, connected with a further spring 29, Spring: block 29 consists of a spring 30, extension, which is equipped with plugs 31 at the ends and with hinged bolts 32, which are hinged on one side with the tape 28, and on the other side - with bracket 33 fixed on stand 6.. The device works as follows. If the spring block | C16 provides the necessary tension force of the flexible element 3, the spring 29 is turned off and does not participate in the operation of the device .; In & THOMAS, the torque of the balancer 11, generated by the force in the flexible element 3 relative to the axis of rotation 8 of the rack 6, is equalized by the moment created by the tension spring 17 on a certain shoulder of the cam 14 of the box 12, which is connected 17 by means of a tape 15 fixed on the disk cam 14 and pivotally connected to the tension spring 17. If the spring unit 16 does not provide the necessary tension of the flexible element 3, the spring 25 is activated. For this, the rod 25 of the clamp 24 is introduced into the Verstov 27 the cam disc 26, they are rigidly connected. When the cam disc 26 is rotated about the axis 8, the tape 28 is wound on the cam 26, stretching the expansion tension spring. In this case, the torque of the balance bar 11, generated by the force in the flexible element 3 relative to the axis of rotation 8 of the column 6, is balanced by the moment created by the two tension springs 17 and 30 on the respective arms of the disk cams 14 and 26. The disk cam 26 is connected to the spring 30 stretching when the tape 28 is rigidly fixed on the cam and pivotally connected to the tension spring 30. Introduction of a lock 24 and an additional disk cam 26 connected to the spring block 29 mounted on a stand 6 to the device allows be the unit to operate with different nomenclature flexible elements. The invention The device for adjusting the tension of the same NIN of the flexible element according to the author. 5532 O2, characterized in that, in order to broaden the range of generated tension forces, the device is equipped with an additional. telny spring block l, and on the sleeve. Racks of monitors with the possibility of SOP1. The company has an additional cam made with a hole and interconnected by means of a tape with an additional spring block, while on the balance bar axis there is a rigidly fixed retainer carrying a movable rod that is inserted into the hole of the additional cam. 1 $ 2 2V
