Description

Известные Механические тормоза дл  испытани  двигателей внутреннего сгорани  при изменении коэфициента трени  м.ежду тормозной лентой и барабаном выход т из равновеси  и требуют поэтому посто нного наблюдени  за ними во врем  работы и регулировани  степени нат жени  Ленты.The known Mechanical brakes for testing internal combustion engines when the friction coefficient changes between brake tape and drum are out of balance and therefore require constant monitoring during operation and adjustment of the belt tension.

Предлагаемый торМОЗ того же назначени   вл1 етс  саморегулирующимс . С этой целью в нем тормозна  лента со свисающими с тормозного барабана концами св зана одним из них грузом., а другим-с пальцем на торце шкива, соосного с тормозным барабаном и нагруженного грузом, создающим моМент, противоположный тормозному, и поддерживающим посто нный тормозной момент путам изменени  угла обхвата лентой тормозного барабана .The proposed tormoz of the same designation is self-regulating. To this end, it contains a brake tape with ends hanging from a brake drum and one of them is loaded. And the other with a finger on the end of a pulley coaxial with the brake drum and loaded with a load that creates a torque opposite to the brake brake and supports a constant braking torque. putam change the angle of the grip tape brake drum.

На чертеже изображена схема тормоза.The drawing shows the brake circuit.

На тормозной барабан 1 накинута тормозна  лента со свисающими концами, из которых один несет груз 3, а другой соединен с пальцем 4 на торце шкива 5, расположенного соосно с барабаном / и нагруженного противовесОМ 6, создающим момент, обратный тормозному .A brake tape with hanging ends is pulled over the brake drum 1, one of which carries the load 3 and the other is connected to the finger 4 at the end of the pulley 5, which is located coaxially with the drum / and loaded with a counterweight 6, creating a moment that is inverse to the brake.

При вращении тормозного барабана / тормозна  лента 2 под действием: груза 3 и трени  между ней и барабаном стремитс  вращатьс  вместе с последним. Этому преп тспвует противовес 6, подвешенный к шкиву 5, соеди еННому с тормозной лентой посредством пальца 4.When the brake drum / brake belt 2 rotates, under the action of: load 3 and friction between it and the drum, it tends to rotate with the latter. This prevents the counterweight 6, suspended from the pulley 5, connected to the brake belt with a finger 4.

При увеличении во врем  работы коэфициента трени  лента начинает перемещатьс  в наеравлении вращени  барабана. При этом угол охвата лентой барабана будет уменьшатьс  до тех пор, пока не восстановитс  равновесие действующих на нее сил. При уменьшении коэфициента трени  лента под воздействием противовеса 6 перемещаетс  в обратном направлении, отчего угол охвата ею барабана будет увеличиватьс , пока снова не восстановитс  равновесие.When the friction coefficient increases during operation, the tape begins to move in the direction of rotation of the drum. In this case, the angle of coverage of the drum with the drum will decrease until the balance of the forces acting on it is restored. When the friction coefficient decreases, the tape under the influence of the counterweight 6 moves in the opposite direction, causing the angle of its coverage of the drum to increase until the balance is restored again.

Таким образом, как бы ни измен лс  коэфициент трени  между лентой и барабаном, тормозной момент на барабане будет поддерживатьс  посто нным.Thus, no matter how the friction coefficient between the belt and the drum changes, the braking torque on the drum will be kept constant.
