Description
Technical field
The utility model relates to a kind of automobile differential, is specifically related to a kind of automobile differential lock.
Background technique
Automobile differential is the main part of ransaxle.Open differential is made up of parts such as planetary pinion, planetary wheel carrier (differential carrier), differential gears.The power of motor enters differential mechanism through transmission shaft, Direct driver planetary wheel carrier, then drives left and right two semiaxis by planet wheel, drives left and right wheel respectively.The designing requirement of differential mechanism meets: (left half axle rotating speed)+(right axle shaft rotating speed)=2 (planetary wheel carrier rotating speed).When automobile is kept straight on, left and right wheel is equal with the rotating speed of planetary wheel carrier three is in state of equilibrium, and three's state of equilibrium is destroyed when automobile turning, nearside wheel rotating speed is caused to reduce, outboard wheel rotating speed increases, meet two sidecar wheels and make Unequal distance traveling with the form of pure rolling as far as possible, reduce the friction on tire and ground.
General vehicle is two-wheel drive, when in driving wheel is skidded or be unsettled, whole vehicle can be made to lose driving force.Now just need differential mechanism locking, and then make two driving wheels have identical rotating speed.At present to realize this technology, whole differential mechanism must be changed, cost is thousands of up to ten thousand at most at least.
Model utility content
The utility model is intended to provide a kind of increases the automobile differential lock that assembly can realize the locking of differential mechanism on original differential mechanism.
Automobile differential lock in this programme, comprise two planetary pinions and two differential gears that are positioned at differential mechanism bulb, the rotation axis coincident of described differential gear and being all meshed with planetary pinion, described differential mechanism bulb internal fixtion is connected with driven unit, described planetary small end is all fixedly connected with fixing locking axle sleeve, and locking shaft puts and is arranged with locking sliding sleeve; Described locking sliding sleeve and locking shaft cover are in axial sliding connection, and are moved between lock position and unlocked position by driven unit.
The utility model has the following advantages: (1) is all fixedly connected with locking axle sleeve due to planetary small end, locking shaft puts and is arranged with locking sliding sleeve, when locking sliding sleeve and two locking axle sleeves all partially overlap, planetary pinion locking, now can realize differential mechanism locking; When locking sliding sleeve only overlaps with a locking axle sleeve, planetary pinion unlocks; (2) because locking axle sleeve, locking sliding sleeve are between two planetary pinions, driven unit is positioned at differential mechanism bulb, and original differential mechanism increases locking axle sleeve, locking sliding sleeve, driven unit, greatly reduces the cost changing differential lock.
Further, described driven unit comprises two symmetrically arranged electromagnet and a spring shift fork; The two ends of spring shift fork are fixedly connected with the mobile terminal of electromagnet, are fixedly connected with in the middle part of it with locking sliding sleeve.When starting electromagnet, under the drive of spring shift fork, locking being slided between lock position and unlocked position and moves.And electromagnet small volume, occupy little space, be convenient to install.
Further, described spring shift fork is bent by an one metal wire and forms, and its two ends and middle part are arc-shaped, and the radius of arc at middle part is greater than the radius of arc at two ends; The joint of electromagnet and locking sliding sleeve and spring shift fork is equipped with annular recess, is convenient to install.
Further, described electromagnet is fixedly connected with the inwall of differential mechanism bulb by the support of L-type.
Further, described two locking axle sleeves are spline housing, and described locking sliding sleeve is the internal spline sliding sleeve be mated.
Further, described locking axle sleeve comprises long locking axle sleeve and short locking axle sleeve, and the length of described long locking axle sleeve is not less than the length of locking sliding sleeve.
Further, described differential mechanism bulb outer wall has been fixedly connected sequentially circuit supporting dish, pc plate and conductive plate.
