Description

новлен дополнительный клапан, запорный элемент которого поджат пружиной 12 со стороны штоковой полости цилиндра 2. Элемент 9 поджат пружиной 13 в сторону бесштоковой полости цилиндра 2. Элементы 9 и // выполнены с дроссельными отверсти ми .14 и 16. Бесштокова  полость цилиндра 2 св зана с резервуаром./ через клапан 16. Сцепные элементы 17 и 18 буксирного устройства установлены на конце штока 4 и на торцовой стенке резервуара /.An additional valve is inserted whose shut-off element is pressed by the spring 12 on the side of the rod end of the cylinder 2. The element 9 is pressed by the spring 13 to the side of the rodless cavity of the cylinder 2. The elements 9 and // are made with choke holes .14 and 16. The rodless cavity of cylinder 2 is connected with the tank. / through the valve 16. Coupling elements 17 and 18 of the towing device mounted on the end of the rod 4 and on the end wall of the tank /.

Во врем  буксировки прицепа т гачом гидравлический амортизатор полностью раст нут так, что канал 7 перекрыт втулкой крышки 5. Когда т гач начинает замедл ть движение, амортизатор стремитс  сжатьс , но хот  в этот момент элемент 9 открыт, жидкость не может проходить через проточку 6, т. е. канал 7 перекрыт, поэтому жидкость перетекает из бесштоковой полости цилиндра 2 в резервуар i/ через суженный клапан 16. В то же врем  элемент /./ отходит от крышки 5, пропуска  жидкость из полости резервуара / в штоковую полость цилиндра 2.During trailer towing, the hydraulic shock absorber is fully extended so that channel 7 is blocked by cover sleeve 5. When the speed damper starts to slow down, the shock absorber tends to compress, but although at this point element 9 is open, the fluid cannot pass through the groove 6, i.e., channel 7 is blocked, therefore the fluid flows from the rodless cavity of cylinder 2 to reservoir i / through the narrowed valve 16. At the same time, the element /./ moves away from cover 5, the liquid passes from the cavity of the reservoir / to the rod cavity of cylinder 2.

. При дальнейшем сжатии амортизатора канал 7 открываетс , и жидкость перетекает из бесштоковой полости в штоковую полость цилиндра 2, при этом объем жидкости , протекающей .через клапан 16, уменьшаетс  в отношении, пропорциональном отношению площади поршн  5 к площади поперечного сечени  штока 4. Величина амортизации падает в той же пропорции.. Upon further compression of the shock absorber, channel 7 opens and fluid flows from the rodless cavity into the rod end of cylinder 2, and the volume of fluid flowing through valve 16 decreases in proportion proportional to the ratio of the piston area 5 to the cross-sectional area of the rod 4. The damping value drops in the same proportion.

Когда т гач снова трогаетс , амортизатор , наход щийс  в сжатом состо нии, начинает постепенно раст гиватьс , при этом элементы IJ и 9 клапанов закрыты, и жидкость перетекает в полость резервуара / через отверстие ,15, тем самым см гча  выт гивание амортизатора. В бесштоковую полость цилиндра 2 жидкость возвращаетс  . через клапан (М. Перетекание iMSirocfи че.- рез отверстие М до момента закрыти  канала 7 также см гчает выт гивание амортизатора .When the pump is again moved, the shock absorber, in its compressed state, begins to gradually expand, with the valve elements IJ and 9 closed, and the liquid flows into the reservoir cavity / through the opening 15, thereby softening the shock absorber. The fluid returns to the rodless cavity of cylinder 2. through the valve (M. Flowing iMSirocfi) - through the hole M until the closing of the channel 7 also softens the drawing of the shock absorber.

В другом варианте выполнени  амортизатора (фиг. ,3) элемент 11 заменен тарельчатым элементом 19, поджатым гофрированной пружинной щайбой 20. Роль отверсти  15 выполн ет зазор 21. Работа амортизатора протекает так же, как и в первом варианте .In another embodiment of the shock absorber (Fig. 3), the element 11 is replaced by the plate element 19, pressed by the corrugated spring plate 20. The role of the hole 15 is performed by the gap 21. The operation of the shock absorber proceeds in the same way as in the first embodiment.
