Description
Technical field
The utility model relates to a kind of diff lock of using on four-wheel Light-duty Vehicle and all-terrain vehicle.
Background technique
During vehicle driving, the distance that left and right wheel rolls across in does not at one time often wait.For example, inside and outside both sides wheel travel is obviously different during turning, and promptly the distance that rolls across of outboard wheels is greater than inboard wheel; When vehicle travels on uneven road surface, because the distance that road surface waveform difference also can cause the both sides cartwheel roll to cross does not wait; Even on straight road surface, travel, because the influence of factors such as tire pressure, loading of tire, treadwear degree difference and foozle can cause that also left and right wheel does not wait left and right wheel travel because of rolling radius is different.Can produce driving wheel slippage or trackslip on the road surface like this during vehicle driving inevitably, not only can aggravate the consumption of tire wear and power and fuel, and may cause turning to manoeuvring performance and worsen.So under the cruising condition, wheel is not slided as far as possible.For this reason, on vehicle structure, must guarantee that each wheel might rotate with different angular velocity, therefore, all use differential cross pin on the vehicle.
More often be applied at present on four-wheel Light-duty Vehicle and the all-terrain vehicle is a kind of cone gear formula differential mechanism of realizing differential action on the transmission shaft that is installed in.Differential casing is made up of left shell and right shell with bolton, in the vehicle that adopts chain transmission, the power input sprocket is fixed by bolts on the flange of differential right casing, planet pin is packed into and is located with stop pin behind the differential carrier, planetary pinion is meshed with two differential gears respectively, the axle journal of differential gear is supported on respectively in the corresponding left and right seat of the differential carrier hole, and links to each other with semiaxis by spline.Power ultromotivity input sprocket, differential carrier, planet pin, planetary pinion, differential gear and semiaxis are exported to driving wheel.When the vehicle straight-line travelling, wheel suffered running resistance in both sides equates that planetary pinion keeps balance, i.e. not rotation of planet gear, and can only revolve round the sun with planet gear shaft and differential carrier, so two-semiaxle does not have speed discrepancy, differential mechanism does not play differential action.When travelling when turn inside diameter or on rough road, the running resistance difference that the both sides wheel is suffered, to destroy planetary balance like this, planetary pinion is except revolving round the sun with differential carrier, the star gear shaft rotation of also will detouring, make the both sides wheel with different rotational speed, differential mechanism plays differential action.
The locking coefficient of common bevel differential is generally 0.05～0.15, the torque ratio of two-semiaxle is 1.11～1.35, the torque difference of left and right half is little, so can think distribute to two-semiaxle torque about equally, such allocation proportion is suitable for four-wheel Light-duty Vehicle of travelling on good highway section and all-terrain vehicle.But, when four-wheel Light-duty Vehicle and all-terrain vehicle are sailed the highway section being difficult to walk, when for example on highway sections such as sandy beach, mire, ice and snow, travelling, when the coefficient of attachment on one side drive wheel and ground is very little, although the opposite side wheel has and good the adhering in ground, its driving torque also has to similarly reduce with adhering to the little side of coefficient, can't bring into play potential tractive force, to cause the vehicle driving difficulty.If the employing locking differential can overcome this defective, but because complex structure must possess hydraulic pressure or air-operated control mechanism, and bulky, difficulty is installed on four-wheel Light-duty Vehicle and all-terrain vehicle, handle also inconvenience, thereby be difficult to apply.
