The model utility content
Technical problem to be solved in the utility model provides a kind of tooth embedding clutch type limited-slip differential, and it is big that it possesses transmitting torque, and the differential design compactness is beneficial to integrated characteristics.
For solving the problems of the technologies described above, the utility model proposes following technological scheme: a kind of tooth embedding clutch type limited-slip differential, comprise common planetary gear type differential mechanism, hydraulic pressure or pneumatic control mechanism, the engagement of hydraulic pressure or pneumatic control mechanism urges jaw clutch, it is characterized in that, jaw clutch is installed in the described differential casing, jaw clutch comprises main, passive end face tooth, initiatively the end face tooth is connected with differential casing by spline, and passive end face tooth connects with side gear shaft by spline.
As further improvement project, the hydraulic pressure of described hydraulic pressure or pneumatic control mechanism or pneumatic cylinder connect platen by hydraulic pressure or pneumatic cylinder piston, this platen promotes the slip platen by thrust roller bearing, described thrust roller bearing is connected with slip platen drive fit, described slip platen is connected with the differential cover transition fit, described slip platen connects described active end face tooth, between described active end face tooth and differential cover Returnning spring is installed.After the solenoid valve release, described accumulator and described hydraulic pressure or pneumatic cylinder disconnect, and do not have in hydraulic pressure or the pneumatic cylinder to be equipped with and press, and under the effect of described Returnning spring restoring force, described master, passive end face tooth are separated from each other.
Further, described hydraulic pressure or pneumatic control mechanism comprise hydraulic pressure or pneumatic cylinder, solenoid valve and accumulator, described hydraulic pressure or pneumatic cylinder are installed in the reducer shell, described hydraulic pressure or pneumatic cylinder are connected with described accumulator, described accumulator connects described solenoid valve, and described solenoid valve receives the control signal break-make of Auto Electronic Controlled System.
Preferably, described master, passive end face tooth are the trapezoid tooth.
The utility model is the structural type that differential lock is integrated in differential mechanism inside with jaw clutch, main, passive end face tooth radial dimension is strengthened, with respect to traditional outer structure of differential mechanism that independently is arranged in, the moment of torsion that this castellated limited-slip differential can transmit is bigger, and the also simpler compactness of structure, easy to operate, be applicable to heavy off-road vehicle.Simultaneously, it adopts the ACTIVE CONTROL mode, in conjunction with electric-controlled hydraulic or pressure technology, makes the jaw clutch that is integrated in differential mechanism inside limit clutch in the rotating ratio scope at main passive end face tooth, has realized not shut-down operation.
