A shaft of the left half shaft gear is connected with a left half shaft of the left half shaft gear through an independent coupler, the independent coupler is movably connected with a coupling slide sleeve in sleeved mode, the coupling slide sleeve is fixedly connected with one end of the fork, the other end of the fork is fixedly connected with a rack which is meshed with a gear which is connected with an output shaft of an auxiliary motor. The differential mechanism is compact in structure, can improve driving performance of a whole car, can improve the driving slip phenomenon of an common differential mechanism, can lock car wheels when the car wheels slip, and avoids high-speed idling of the car wheels, thereby improving driving performance of a dune buggy and a pickup on sand and other greatly severe road conditions.
Description
Technical field
The utility model relates to a kind of differential mechanism, is specifically related to a kind of differential mechanism of translator auxiliary drive fork type slide limiting differential lock.
Background technique
Along with the development of auto manufacturing technology, output and the sales volume of beach buggy and farmer's car increase severely day by day, and the transferring power technology of beach buggy and farmer's car is constantly innovation also.Wherein, differential mechanism is a kind of device with transmission of power and power distribution function.The Main Function of differential mechanism is, in the process of moving, and when beach buggy runs into when turning, can automatically regulate the rotating speed of inside and outside wheel, to guarantee that foreign steamer can not drag on the road surface, avoid the wearing and tearing aggravation of tire, thereby guarantee the safety coefficient of moving vehicle, improve the service life of retarder.
But existing differential mechanism when running into the road surface of muddy and very severe such as a certain bridge of beach buggy or farmer's car, owing to adhesion is inadequate, will produces and skid when running into extremely abominable road conditions; And an other bridge is affected by it, and driving force does not forward increase counter subtracting, until its wheel-slip high speed rotating, causes the tractive force of car load because greatly consuming less than running resistance, so that other one side can only be on the way as you were, causes the car load can not be to overtake.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of differential mechanism of translator auxiliary drive fork type slide limiting differential lock, and it can avoid driving wheel to skid under abominable road conditions.
For solving the problems of the technologies described above, the technical solution of the differential mechanism of the utility model translator auxiliary drive fork type slide limiting differential lock is:
Comprise driving gear, driving gear is meshed with two driven gears up and down respectively; Driving gear and driven gear are arranged in the differential mechanism shell 1; Two driven gears are meshed with left half axle gear 2 jointly up and down; The axle of left half axle gear 2 is realized being connected by transfer coupling 4 with left half axle 5; Movable sheath is provided with shaft coupling sliding sleeve 3 on the transfer coupling 4; Shaft coupling sliding sleeve 3 is fixedly connected with an end of shift fork 6, and the other end of shift fork 6 is fixedly connected with tooth bar 11; Tooth bar 11 is meshed with gear, and gear connects the output shaft of helper motor 7.
Be provided with internal spline on the described shaft coupling sliding sleeve 3, the internal spline of shaft coupling sliding sleeve 3 matches with external splines on the left half axle gear 2.
The internal spline arranged outside of described shaft coupling sliding sleeve 3 has external splines, and the external splines of shaft coupling sliding sleeve 3 matches with the internal spline of differential mechanism shell 1.
The technique effect that the utility model can reach is:
The utility model has additional the motor driving shift fork at open differential, and shift fork promotes the shaft coupling sliding sleeve, thereby pins one side of differential mechanism.
The utility model compact structure can improve the driveability of car load, improves the skidding of travelling of open differential; The utility model can pin wheel when wheel-slip, avoid the wheel fast idle, thereby improves beach buggy, the farmer's car driveability on sandy beach and extremely abominable road conditions.
