Description

Forced locking differential without stopping
Technical field
The present invention relates to the wheeled vehicle forced locking differential without stopping.
Background technique
For solve that symmetric type cone planetary gear differential mechanism exists when the driving wheel skid, another driving wheel rotating speed that just runs out of steam is zero, the critical defect that vehicle just halts, people are on the basis of symmetric type cone planetary gear differential mechanism, and having invented " locking differential " has promptly increased " differential lock ".Though this differential mechanism that locks solves the shortcoming that open differential exists, the differential lock of present existing forced locking formula difference device all needs to stop and just can hang up.When running into vehicle slip, needing stops earlier hangs up differential lock and starts to walk, hangs not only troublesome poeration of differential lock and stop, and the recurrence step need overcome the resistance that manys big when travelling, can increase the obstacle detouring difficulty of vehicle.
Summary of the invention
The present invention is conceived to solve the problem that the forced locking differential mechanism is handled inconvenience, hangs up the purpose of differential lock immediately smoothly in order to realize not stopping, and proposes forced locking differential without stopping.
Technical conceive of the present invention is: when a driving wheel of vehicle skids sky when sailing, realize not stopping with two differential gear forced lockings together.
For this reason, technological scheme of the present invention is: forced locking differential without stopping comprises the symmetric type cone planetary gear differential mechanism of being made up of differential carrier, cross axle, planetary pinion, right axle shaft gear, right axle shaft, left half axle, left half axle gear; In the left and right half gear, be provided with jaw positivecontact coupling with elastic gap; Wherein jaw positivecontact coupling meshes near the internal spline that an end of semiaxis is provided with external splines and differential gear, and the other end of two jaw positivecontact coupling constitutes tooth-like clutch structure or castellated clutch structure in cross axle, and between be provided with Returnning spring; The angle of clearance of jaw positivecontact coupling with elastic gap is greater than 1/2nd of the tooth form angle of the flute profile angle of tooth-like clutch structure or castellated clutch structure; In left half axle or right axle shaft, be provided with the push rod roof pressure that is slidingly matched with described semiaxis endoporus at the end of corresponding jaw positivecontact coupling, on described semiaxis, be set with slip ring near semiaxis; Semiaxis is provided with axial groove, and a bearing pin passes the axial groove two ends and is fixed on the slip ring, and the bearing pin cylindrical contacts with the end face of push rod in semiaxis; Be fixed with cylinder assembly on axle housing, cylinder assembly drives slip ring by shift fork.
The working procedure of described forced locking differential without stopping: when needs together the time, start cylinder assembly with two-semiaxle gear forced locking, move one of them shaft joint by push rod, the locking position enters engagement, thereby two-semiaxle gear forced locking.Wherein, the jaw positivecontact coupling that two ends have an elastic gap all plays buffer function and can guarantee that the locking position meshes rigid collision when avoiding the locking position to enter engagement smoothly.Thereby guaranteed can be immediately forced locking when vehicle does not stop smoothly.
Good effect compared with prior art: existing locking differential is simple in structure, is easy to make, and cost is low, but because of handling inconvenience, so use not extensive.The present invention can solve its problem of handling inconvenience well, the control system that the electricity of the maturation that adopts, gas, machinery organically combine, electric knob can be pressed and unclamp to driver as required at any time, just can realize the purpose of differential mechanism forced locking and disengagement immediately smoothly.
