Известен самоблокирующийся дифференциал транспортного средства, содержащий установленные в корпусе полуосевые шестерни, оси со свобод- ₁₀но расположенными сателлитными шестернями и направляющие, расположенные в пазах, выполненных в корпусе^· Недостатком дифференциала является сложность конструкции, обусловлен- ₁₅ная наличием промежуточных деталей, что также увеличивает габаритно-весовые показатели дифференциала.Known vehicle limited slip differential comprising side gears installed in the housing, with the free axle ₁₀ but located the satellite gears and guides located in grooves formed in the casing of the differential ^ · drawback is the complexity of design, obuslovlen- ₁₅ Naja presence of spacers, which also increases the overall weight indicators of the differential.

Цель изобретения - упрощение конструкции. 20The purpose of the invention is to simplify the design. 20

Цель достигается тем, что в дифференциале оси расположены с эксцентриситетом к центрам начальных окружностей зубьев сателлитных шестерен и установлены в направляющих для перемещения в пазах корпуса.The goal is achieved by the fact that in the differential the axes are arranged with eccentricity to the centers of the initial circumferences of the teeth of the satellite gears and are installed in the guides for movement in the grooves of the housing.

Дифференциал транспортного средства содержит корпус 1 со съемной крышкой 2, в котором установлены полуосевые конические шестерни 3 и кони ческие сателлиты 4. Отверстия в сателлитах для установки их на крестовине 5 выполнены эксцентрично центрам начальных окружностей их на крестовине 5 устанавливается в корпусе дифференциала в подвижных направ!ляющих 6, имеющих возможность пере умещаться в пазах 7 корпуса дифференциала в направлении полуосевых шестерен.In FIG. 1 shows a differential, sectional perspective view, ’in FIG. 2 satelliteLite gear with an eccentric hole for mounting it on the crosspiece, section, ’in FIG. 3” is the same, top view; in FIG. 4 is a diagram of the sinusoidal movement of the spider relative to the unfolded surfaces of the semiaxial gears with the fully locked right gear and one full revolution of the satellite. The vehicle differential comprises a housing 1 with a removable cover 2, in which semi-axial bevel gears 3 and conic satellites are installed 4. The holes in the satellites for mounting them on the cross 5 are eccentric to the centers of their initial circles on the cross 5 installed in the differential housing in movable directions! 6, having the ability to fit in the grooves 7 of the differential housing in the direction of the semi-axial gears.

Дифференциал работает следующим образом.The differential works as follows.

При установившемся движении по прямой твердой дороге крестовина 5 сателлитов чаще всего будет занимать среднее положение при смещении вперед - по ходу вращения (фиг. 4). В дифференциале устанавливается равновесием плечи а=Ь, силы Q и Р= “Q^+Q^. Крутящий момент М_КрТрансмиссии распределяется между полуосевыми шестернями поровну 0,5 М=аWith steady motion along a straight solid road, the crosspiece of 5 satellites will most often occupy a middle position when shifting forward - in the direction of rotation (Fig. 4). In the differential, the shoulders a = b, the forces Q and P = “Q ^ + Q ^ are established by equilibrium. The torque M _To rTransmission is distributed between the semi-axial gears evenly 0.5 M = a

При уменьшении силы Q₄ или Q^aB? томатически происходит и изменение плеч а и b за счет перемещения крестовины 5, при этом крестовина смещается в сторону наиболее нагруженной полуосевой шестерни, отчего подводимый к ней крутящий момент увеличивается.With decreasing force Q ₄ or Q ^ aB? the change of the shoulders a and b occurs automatically due to the movement of the spider 5, while the spider is shifted towards the most loaded semi-axial gear, which increases the torque supplied to it.

Установка на автомобилях эксцентричных сателлитов и плавающих кре5 стовин не требует значительных конструктивных изменений ведущих мостов и раздаточных коробок и не на много усложнит их изготовление.The installation of eccentric satellites and floating joints on cars does not require significant structural changes of the drive axles and transfer boxes and will not complicate their manufacture much.

Claims

The invention relates to the automotive industry, and more specifically to vehicle differentials and can be used on automobiles, wheeled tractors for driving axles and transfer boxes. A self-locking vehicle differential is known, containing axle sheathes mounted in the housing, axles with freely positioned satellite gears. and guides arranged in grooves made in Kopnyce l The disadvantage of the differential is the complexity of the design, due to the presence of KSR parts, which also increases the dimensions and weight of the differential indicators. The purpose of the invention is to simplify the design. The goal is achieved by the fact that in the differential, the axes are located with an eccentricity to the centers of the initial circumferences of the teeth from the telite gears and mounted in guides for movement in the slots of the housing. Figo 1 shows the differential, a general view in section; in fig. 2 satellite gear with an eccentrically made opening of its installation on the cross, a section; Fig. A, top view J in Fig. A is a diagram of a sinusoid movement of the crosspiece with respect to the unfolded surfaces of the semi-axial gears with the right-hand gear fully locked and one full rotation of the satellite4 and conic satellites. The holes in the satellites for mounting them on the crosspiece 5 are made eccentrically to the centers of the initial circumferences of them on the crosspiece 5 is installed in the differential case in the movable guides 6, which can be moved. 39 to fit in the slots 7 of the differential housing in the direction of the semi-axial gears The differential pafJoraer as follows. When steady motion on a straight hard road, the crosspiece of the 5 satellites will most often take a middle position when shifted forward - in the direction of rotation (FIG. K), in the differential equilibrium shoulders, Q forces (i and Р "Q + Q ,. The torque of the M pTransmission is distributed between the half-axle gears of equal 0.5 H, When the force Q decreases or the arms a and b also change, the crosses 5, the spider shifts to the S side of the most loaded semi-axle gear, which increases the driving torque. Depending on the eccentricity value, the distribution of the steepness and its momentum on the semi-axial gears can vary from 20 to 80, which is very favorable for increasing patency of the vehicle and reduction of fuel consumption 6 due to a sharp decrease in wheel slip; Installation of eccentric satellites and floating crosses on cars does not require significant structural changes. axles and transfer boxes and not much complicate their manufacture. Claims of the invention Self-locking vehicle differential containing semi-axle gears mounted in the housing, axles with freely positioned satellite gears and guideways located in the grooves made in the housing, which, in order to simplify the design, axes with eccentricity To the centers of the initial circumference of the teeth of the satellite gears and mounted in guides for movement in the slots of the housing.
