Description

The invention relates to light industry, medical physical culture and sports medicine, namely, as a load node of the simulator and other devices requiring dosed resistance to the applied force. It can be widely used in the design of various types of sports and fitness equipment, for example a simulator for training rowers, arm wrestlers, cyclists, weightlifters, wrestlers and other sports, as well as for health and medical purposes.

In the known brake devices of the simulators, various types and sizes of springs, tubular expanders, drums with pads, hydraulic cylinders, electromagnetic powder brakes are used for load resistance [1-19].

The disadvantages of the known brake devices include: the complexity and bulkiness of the design, the limitation of the possibility of dosing the load during reciprocating motion, there are no conditions for accurate dosing of the load, and the use of simulators with an electromagnetic powder brake device requires special safety precautions.

Close in technical solution to the proposed invention is the braking device of the simulator according to the copyright certificate of the USSR 685287, А63В 69/06, А61Н 1/02. publ. 09/15/1979 [2], containing a drum with blocks and a prismatic cam located between them, mounted on the axis of the rotation regulator; hydraulic cylinders with manometer; leverage. Levers are considered the stroke to the user. In this case, the applied forces are transmitted through the cables to the hydraulic cylinders, and from them to the pressure gauges, which show the magnitude of the applied force by the user. The forces, the resistance to movement of the levers are created by the friction forces of the pads pressed by the cam to the surface of the drum.

The brake device of the known simulator [2] has advantages over others, but does not completely eliminate their disadvantages.

The objective of the proposed technical solution is to develop a compact brake device of the simulator with a simplified design, with the ability to provide the load during the reciprocating movement, ensuring the regulation of the degree of load and its accurate dosing.

In FIG. 1 is a cross section of the device in the phase of the beginning of movement, for example, the phase of the beginning of the stroke for the simulator boat.

In FIG. 2 is a cross-sectional view of a device in a motion completion phase, for example, a stroke completion phase for a boat simulator.

In FIG. 3 - details of the device in the circuit of its assembly.

In FIG. 4 - load scale.

The brake device for the simulator (Fig. 1-3) has a housing 1, an axis 2, at the lower end of which there is a fastener 3 for swivel 4 with the bracket 5 (Fig. 2). The axis 2 is coaxially and rigidly connected to the main disk 6, on which a wear-resistant plate 7, for example, of Kevlar fiber, is fixed. A wear plate 8 is attached to the wear plate 7 to provide friction during rotation, the pressure disk 8, which is rigidly connected to the pressure plate by strips 9 and 10, and the pressure disk 11 has a coaxially pressed sleeve whose edges 12 and 13 extend beyond the upper and lower plane of the pressure disk 11. The upper edge 12 of the sleeve has a rounded end 14, and the lower edge 13 of the sleeve has an end 15, beveled at an angle of 8 °. The angle of inclination of the end face 15 of the edge 13 of the sleeve of the pressure plate 11 may be more or less depending on the type of simulator, and to increase the load, the angle is increased, and to decrease it is reduced. Between the pressure disk 8 and pressure disk 11 there is a pressing device with two coaxial disks 16 and 17, between which the spring is placed 18. The lower disk 16 is rigidly aligned with the studs 19 and 20, which pass through the holes 21 and 22 of the upper disk 17. On the surface of the upper of the disk 17 facing the pressure disk 11, a protrusion 23 is fixedly fixed with a rounded free end 24 (Fig. 3), which is aligned with the beveled end 15 of the sleeve 13 of the pressure disk 11. The disks 16 and 17 of the pressing device can progressively move relative to axis 2 along key 25, which blocks their rotation. The pressure disk 8 and pressure disk 11 can carry out synchronous rotational-translational motion relative to axis 2. Axis 2 at the free end has a threaded thread 26 under the nut 27 with the washer 28 (Fig. 3). The nut 27 is equipped with a handle 29 for convenient rotation of the nut 27 when the brake load changes with increasing or decreasing friction when the pressure disk 8 moves along the wear-resistant lining 7 of the main disk 6. Dosing of the load is carried out on a scale 30 with a cursor located on the nut 27 (Fig. 4). A pipe 31 is rigidly attached to the pressure disk 11, to which the lever 32 is attached.

The principle of operation with the brake device is as follows.

1. The brake device is mounted on the bracket 5 of the simulator, a lever 32 is attached to the nozzle 31 for reciprocating movements in the set rhythm according to a predetermined program.

2. Using a dynamometer, apply force to the lever 32 (Fig. 2) and mark the load scale 30 (Fig. 4). When the nut 27 is rotated using the knob 29 in a “clockwise direction”, the load increases, and when rotated counterclockwise, the load decreases.

Positive effect when using the simulator:

1. The brake device has a compact appearance and simple design, the details of which can be made without the use of complex technologies;

2. Simplified load dosing when used on a variety of simulators;

3. There is the possibility of dosing the load during the reciprocating movement between the phases of completion and the beginning of the motor phase, for example, the completion and start of the stroke on the simulator boat.
