Description

33

Передний конец направл ющих 7, 8 шарнирно св зан с опорной плитой 13, имеющей втулки скольжени 17.The front end of the guides 7, 8 is pivotally connected to a base plate 13 having sliding sleeves 17.

С целью исключени продольното перемещени опорной плиты 13 на направл ющих 7, 8 с помощью штифтов 18 жестко установлены двухзвенные рычаги 19-, 20, соедин ющиес с основанием 1 подвески посредством кронштейнов 21, 22 с ос ми.In order to eliminate the longitudinal movement of the base plate 13 on the guides 7, 8, using the pins 18, two-link levers 19, 20 are rigidly mounted, which are connected to the suspension base 1 by means of brackets 21, 22 with the axles.

В образованном нромежутке между втулками опорной плиты 13 перемещаютс ползуны 23, 24, св занные пальцем 25 с наклонными рычагами 26, 27.In the formed gap between the sleeves of the base plate 13, the sliders 23, 24, which are connected by a finger 25 with inclined levers 26, 27, move.

При вращении регулировочного винта 14 руко тки 15 каркас 2 сидень с помощью заднего 3 и передпего 4 кронштейнов перемещаетс по направл ющим 7, 8 и втулкам 11, 12 в продольном направлении.When the adjusting screw 14 of the handle 15 is rotated, the frame 2 of the seat with the help of the rear 3 and front 4 brackets moves along the guides 7, 8 and the sleeves 11, 12 in the longitudinal direction.

Паклонные рычаги 26, 27 нижними концами жестко соединены с трубой 29, шарнирно размещенной в опорах скольжени 30 и 31 основани 1 подвески. Труба 29 с одной стороны жестко св зана зажимом 32 с упругим элементом 33, выполненным в виде металлических етерл{ней, размещенных внутри нее. Свободный конец упругого элемента 33 жестко соединен с рычагом жесткости 34, имеющим цилиндрический прилив, которым он размещаетс в опоре скольжени 35 с возможностью перемеп1,ени в ней. Другим концом рычаг жесткости 34 шарнирно соединен при ПОМОП1И пальца 36 и резьбовой вилки с уширенным зевом 37 с разноходовым винтом 38, ввернутым в резьбовой палец 39, установленный шарнирно на основании 1 подвески.The paconic levers 26, 27 with their lower ends are rigidly connected to the tube 29 pivotally housed in the slide bearings 30 and 31 of the base 1 of the suspension. The pipe 29 is rigidly connected on one side by a clamp 32 with an elastic element 33, made in the form of metal ethers, placed inside it. The free end of the elastic element 33 is rigidly connected to a stiffening lever 34, having a cylindrical tide, with which it is placed in the slide bearing 35 with the possibility of shifting it. The other end of the stiffening lever 34 is pivotally connected with the POMOP1I finger 36 and the threaded plug with a wider shed 37 with razhohodovym screw 38, screwed into the threaded pin 39, pivotally mounted on the base 1 of the suspension.

С помощью механизма регулировки жесткости возможно получение необходимой жесткости упругого элемента 33 в зависимости от веса водител и исключаетс заклинивание в опорах скольжени основани 1 подвески.Using the stiffness adjustment mechanism, it is possible to obtain the required stiffness of the elastic element 33 depending on the weight of the driver and to prevent jamming in the slide supports of the suspension base 1.

Claims

1. Suspension of a vehicle seat, mainly a tractor, comprising a frame, a support plate and a base connected to the support plate by means of two-link articulated levers and an inclined lever, at one end of which a slider is mounted and the other is connected to the support plate through a torsionally adjustable

A resilient element, characterized in that, in order to ensure a stepless adjustment of the seat in the longitudinal direction, it is provided with an additional inclined lever with a slider, as well as a front and rear

brackets fixed to the frame, and guides on which the slides of the inclined levers are movably placed, the rear bracket and the upper ends of the two-link articulated levers are rigidly fixed, and the rods rigidly attached to the front bracket, in this case the sleeves in which are located rods, and a frame position adjustment mechanism is mounted in the front crown.

2. Suspension according to claim 1, characterized in that the Kapicaca position adjustment mechanism consists of a screw fastened on the front bracket and a screw carrier that holds the screw and is fixed on the base plate.
