(54). ПОДВЕСКА ТРАНСПОРТНОГО СРЕДСТВА(54). SUSPENSION VEHICLE

- . ,; . : .1 ; Изобретение .относитс к наземному транспорту, и именно к подвескам транспортных средств.-. ,; . : .one ; The invention relates to ground transportation, and specifically to vehicle suspensions.

Известна подвеска, СООТОЯЩЁЯ из рессоры в каиестве упругого эле . мента, сопр женной с рамой посредством пальца с одной стороны, ас другой - серьги l .The suspension is known, RELATING from a spring in the quality of elastic ale. A copter is attached to the frame with a finger from one side, and the other with an earring l.

Недостатком данной подвески йри движении транспортного средства по криволинейной траектории вл етс перекос моста в горизонтальной плоскости при крене рамы, что приводит к усилению или ослаблению степени йоворачиваемости автомобил .The disadvantage of this suspension of the vehicle moving along a curved path is the axial misalignment of the bridge when tilting the frame, which leads to a strengthening or weakening of the degree of turnability of the vehicle.

Известна также подвеска, содержаща т ги, одними концами шарнирно соединенные с рамой транспортного средства, а другими,- с картером заднего моста и упругие элементы, одними концами соединенные с рамой, а другими кинематически св занные с згшиим j ocTOM 2.A suspension is also known, which has two ends that are pivotally connected to the frame of the vehicle, and others to the rear axle housing and elastic elements that are connected to the frame by one end and kinematically connected to another j ocTOM 2 by other ends.

Недостатком известной конструкции вл етс незначительный перекос моста и, как следствие, незначительное вли ние на поворачиваемость автомобил . A disadvantage of the known construction is a slight tilt of the bridge and, as a result, a slight effect on the vehicle's steering.

Цель изобретени - повышение устойчивости движени транспортного средства при движении.The purpose of the invention is to improve the sustainability of the vehicle when driving.

Поставленна цель достигаетс тем, что шарнирное соединение т г с картером моста содержит расположенные . в продольной, вертикальной плоскости два цилиндрических стержн , расположенных по разные стороны карте10 ра на одной оси, проход щей под угЛЭМ к вертикали, причем верхний цилиндрический стержень смещен назад относительно, оси картера моста.The goal is achieved by the fact that the hinged connection of the t with the crankcase of the bridge contains located. in the longitudinal, vertical plane there are two cylindrical rods located on opposite sides of the map 10 on the same axis, passing under the angle to the vertical, with the upper cylindrical rod shifted back relative to the axis of the crankcase.

Предлагаема подвеска транспорт вого средства включает раму 1, сое20 диненную с задним мостом 2 посредством верхних 3 и нижних 4 т г. Между рамой 1 и нижней т гой 4 установлен упругий элемент - пружина 5 . Т ги 3 и 4 креп тс одним The proposed vehicle suspension includes frame 1, connected to the rear axle 2 by means of the upper 3 and lower 4 tons. A spring element 5 is installed between the frame 1 and the lower link 4. T gi 3 and 4 fasten with one

25 концом к раме 1 оськз 6, а другим к зёщнему мосту 2 посредством накло-. ненных назад стержней 7,выполненных в виде цилиндфа и установленных соосно с обеих сторон кбжуха заднего 25 end to the frame 1 oks 6, and the other to the bridge 2 through the slope-. backward rods 7, made in the form of a cylinder and installed coaxially on both sides of the rear bolster

Claims

30 bridge 2. Suspension works as follows. When the vehicle is moving along a curved path, under the action of centrifugal force, the frame 1 of the vehicle rolls to one side or the other. Along with the frame, axis 6 simultaneously tilts the attachment points of the upper 3 and lower 4 tons. Kinematic features of the suspension consist in attaching the upper and lower t 3 and 4 to the tilted back rod 7, which is angled to the vertical axis. The symmetry of the rear axle 2, & amphibious causes the occurrence of the turning moment of skewing the rear axle in the horizontal plane. This leads to an increase in the degree of understeer of the car and, thus, the stability of its movement. Improving stability when the vehicle is moving in the curves increases safety. Claims of the vehicle suspension, containing ti, with one ends pivotally connected to the frame of the vehicle, and others t with the rear axle housing, and elastic elements, one ends connected to the frame, and the other kinematically connected to the rear axle, This is because, in order to increase the stability of the vehicle by moving, the hinge connection with the crankcase of the bridge contains two cylindrical rods arranged in a longitudinal, vertical plane located on different sides s crankcase on the same axis, extending at an angle to vertikashi, the upper cylindrical rod is offset rearwardly relative karteramosta axis.
