Description
Technical field
The present invention relates to automotive field, more particularly to a kind of reverse transmission and a kind of differential mechanism.
Background technology
When automobile turning, inboard wheel is different with the turning radius of outboard wheels, and the turning radius of outboard wheels is greater than
The turning radius of inboard wheel, this requires the rotating speeds of the outboard wheels in turning to be higher than the rotating speed of inboard wheel, to reduce
Unnecessary power consumption and tire wear.Main part of the automobile differential as drive axle, main function are exactly to both sides
While semiaxis passing power, both sides semiaxis is allowed to be rotated with different rotating speeds, meets two sidecar wheels as far as possible with pure rolling
Form makees Unequal distance traveling.
Fig. 1 shows that a kind of structural schematic diagram of common differential mechanism, the differential mechanism include in the prior art：Planet tooth
Wheel 110, left and right axle shaft gear 120 and tooth rest 130.One end of transmission shaft 140 has driving gear 150, and passes through driving tooth
Wheel 150 is engaged with the driven gear 160 on tooth rest 130, and since the radius of driving gear 150 is smaller, power is from actively
The purpose of deceleration increment may be implemented in gear 150 during being transmitted to the bigger driven gear 160 of radius.
When automobile straight-line travelling, the torque and rotating speed of left and right axle shaft gear 120 are all identical, planet teeth at this time
Wheel 110 does not rotate.When encountering turning situation, inboard wheel is bigger than the resistance that outboard wheels are subject to, or so this when
The torque of axle shaft gear 120 is different, may result in the rotation of planetary gear 120, planetary gear 120 can give inside axle shaft gear
120 1 resistive torques, which are realized, slows down, while also axle shaft gear 120 1 dynamic torques in outside can be given to realize speedup, outer in this way
Side axle shaft gear 120 is faster than the rotating speed of inside axle shaft gear 120, smoothly turns so as to realize.
But there is also defects for above-mentioned differential mechanism, such as when wheel hanging leads to idle running, above-mentioned differential mechanism can
Can endlessly be transmitted to power does not have resistant idle running wheel, vehicle that cannot not only travel forward, a large amount of power
It can be lost in.For this purpose, prior art also teaches limited-slip differential (LSD：Limited Slip Differential), according to reality
The difference of existing mode and parts structure, limited-slip differential can be subdivided into torque sensing type, glutinous coupled mode, screw gear type, standard
The diversified forms such as mechanical.Above-mentioned limited-slip differential can ensure that left and right wheels operate together at work, and will left and right
The speed discrepancy control of wheel ensures normal advance within limits, with vehicle.
But either above-mentioned conventional carrier or limited-slip differential all uses angular wheel, it is multiple that there are structures
It is miscellaneous, the problems such as manufacturing cost is high.

State rotation in the first through hole 221 of the second end plate 220.In the present embodiment, the length of the first shaft part of second eccentric shaft 240
More than the thickness of second end plate 220 so that first shaft part can pass through second end plate 220, be exposed to described
Except second end plate 220, for being connect with extraneous transmission device.In other embodiments, center location can also be only located at
The second eccentric shaft 211 expose second end plate 220, for extraneous transmission device connection.
In above-mentioned reverse transmission, pass through the sliding block and sliding block of the first slide construction 250 and the second slide construction 260
Holder connects the first eccentric shaft 230 and the second eccentric shaft 240, when to 230 input torque of the first eccentric shaft, making described first
When eccentric shaft 230 is rotated in a first direction, first eccentric shaft 230 can drive first slide construction 250 and described
The sliding block opposing slider bracket slide of second slide construction 260, to drive second eccentric shaft 240 along with the first party
It is rotated to opposite second direction, realizes the reverse drive from first the 230 to the second eccentric shaft of eccentric shaft 240.This field skill
Art personnel are it is understood that similarly, above-mentioned transmission device can also be realized from second the 240 to the first eccentric shaft of eccentric shaft
230 reverse drive.
Accordingly, present example additionally provides a kind of differential mechanism, and the differential mechanism includes that above-mentioned reverse drive fills
Set and connect cylinder.
With reference to figure 7, Fig. 7 shows that the differential mechanism of one embodiment of the invention, the differential mechanism include as shown in Fig. 2-Fig. 6
Reverse transmission and connection cylinder 270, the connection cylinder 270 and the first end plate of the reverse transmission (are not shown
Go out) it is fixedly connected with the second end plate 220, constitute differential casing.When applying torque to the differential casing, the differential
Device is suitable for distributing the torque to first eccentric shaft and the second eccentric shaft (not shown).
In the present embodiment, the differential mechanism further includes gear structure 280, and the gear structure 280 is set to the differential
On device shell, inputted by the gear structure 280 when applying torque to the differential casing.The differential mechanism further includes
It is set to the first pipe sleeve (not shown) being connect with the reverse transmission on the first end plate and the second end plate 290 and
