Description
Technical field
The present invention relates to vehicle accessory and vehicular field, in particular to a kind of differential mechanism, transmission device and vehicle.
Background technology
Automobile path of wheel when turning round is circular arc, if automobile is turned to the left, the central point of circular arc is in left side, in phase
In the same time, the camber line that right-hand wheel is walked is longer than left-hand wheel, slow it is necessary to left side wheel in order to balance this difference,
The right wheel is quicker, and the difference of distance is made up with different rotating speeds.In addition, when automobile turning travels up in uneven road surface
When sailing, left and right wheelses is rolled with different rotating speeds, that is, ensure that both sides driving moment makees PURE ROLLING.Differential mechanism is to adjust
The speed discrepancies of left and right wheels and device.In four-wheel drive, in order to drive four wheels, it is necessary to which all wheels are connected
Come, if four wheels are mechanically coupled together, automobile cannot be rotated when curve driving with same speed, be
It can allow automobile curve driving rotary speed basically identical property, at this moment need to add center differential to adjust turning for front and back wheel
Speed difference.
Differential mechanism of the prior art is made up of parts such as planetary gear, planetary wheel carrier (differential carrier), axle shaft gears.Hair
The power of motivation enters differential mechanism through power transmission shaft, directly drives planetary wheel carrier, then drives left and right two semiaxis by planetary gear, point
Left and right wheel is not driven.The design requirement of differential mechanism is met：(planetary wheel carrier turns for (left half axle rotating speed)+(right axle shaft rotating speed)=2
Speed).When automobile is kept straight on, left and right wheel is equal with the rotating speed of planetary wheel carrier three to be in poised state, and in automobile turning
Three's poised state is destroyed, and causes inner side wheel speed to reduce, the increase of outside wheel speed.Differential design ratio of the prior art
More complicated, production cost is higher.
