Description
Technical field
The utility model relates to a kind of technical field of mechanical transmission, and relating to a kind of override type electronics no-spin lockup, is a kind of front axle differential.
Background technique
Differential mechanism is a kind of device with transmission of power and power distribution function, its effect is in the process of moving, when vehicle runs into turning, automatically the rotating speed of inside and outside wheel can be regulated, to ensure that foreign steamer can not drag on road surface, avoid the wearing and tearing of tire to aggravate, thus ensure the safety coefficient of moving vehicle, improve the service life of retarder.
Common differential mechanism is when running into more severe road conditions, when single wheel as beach buggy or farmer's car runs into muddy wet and slippery road surface, because adhesion is inadequate, skidding will be produced, opposite side affects by it at the wheel of good road surface, driving force forward does not increase counter subtracting, and vehicle just loses the power of traveling; If the vehicle of rear wheel drive is when running into road surface, abrupt slope, rear wheel drive force is not enough, and will cause rear wheels slip, vehicle cannot go up a slope.
Model utility content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and provides a kind of override type electronics no-spin lockup with the sliding function of self-locking limit, improves the passing ability of vehicle on abrupt slope and muddy wet-skid road surface.
The technical solution of the utility model is:
A kind of override type electronics no-spin lockup, comprise differential casing, differential cover and master gear, differential cover is fastened on the side of differential casing, master gear is rotating to be bearing in the installation cavity of differential casing, and engage with the input gear axle be arranged in differential casing, there is provided power by input gear axle, it is characterized in that: rotatingly in described installation cavity be provided with driving casing, left half axle cover, right axle shaft cover; Described driving casing and master gear connect as one synchronous axial system, and the sectional shape of driving casing inwall is that reducing is circular, and being specially is uniformly distributed along the circumference by the arc that multistage is identical surrounds; Described left and right half cover is coaxial docking and is mutually arranged on rotatably in driving casing, and left and right half overlaps the left and right half that is in transmission connection respectively; Annular space between driving casing and left and right half overlap is provided with a roller cage and two groups, left and right driven roller, opens spring outward, two groups of driven rollers, outer springs are separately positioned on outside left half axle cover and outside right axle shaft cover, described driven roller is placed in bottom the recess of each arc of driving casing inwall, in each notch simultaneously also offered on roller cage, outer spring head and the tail connect in ring, around hoop between roller cage and driven roller; The side of roller cage is provided with the driving pulling sleeve can stirred roller cage and rotate, and drives the side of pulling sleeve to be provided with adhesive electromagnetic coil, adhesive can drive pulling sleeve after described adhesive electromagnetic coil energising.
In above-mentioned override type electronics no-spin lockup, the medial extremity of described left half axle cover is fixedly connected with one recessed piece, right axle shaft cover medial extremity be fixedly connected with one with the described recessed piece of projection coordinated, left and right half cover by described recessed piece, projection realization be coaxial docking, joint arranges thrust-bearing.
In above-mentioned override type electronics no-spin lockup, the outboard end of described left half axle cover and right axle shaft cover is provided with internal spline, and left and right half cover realizes transmission with left and right half by spline joint.
In above-mentioned override type electronics no-spin lockup, described roller cage offers the notch with driven roller equal amount, be divided into left and right two groups of difference circumferentially, be provided with between the notch that circumference is adjacent and stir groove; Drive pulling sleeve have with described stir that groove matches stir bar, described in stir bar and be plugged in and stir in groove, rotate therefore, it is possible to stir roller cage.
In above-mentioned override type electronics no-spin lockup, the periphery of described roller cage is provided with two coil spring grooves, for holding an outer spring; The middle part of driven roller is provided with a ring annular groove, for a spring outside hoop.
In above-mentioned override type electronics no-spin lockup, the quantity often organizing driven roller is 7.
The working principle of this override type electronics no-spin lockup is as follows:
Input gear axle drives master gear, and linkage driving cover rotates; Because of the effect of an outer spring, controlled by all driven rollers bottom the recess of each arc of driving casing inwall, overlap in complete disengaged condition with left and right half, now the left and right half of propons is without driving, and front-wheel rolls with trailing wheel.
When vehicle runs into abrupt slope or muddy wet-skid road surface, to start front-wheel drive, adhesive electromagnetic coil is then made to be energized, adhesive drives pulling sleeve, stir roller cage to rotate, force each driven roller relative to each arc motion of driving casing inwall, the locking left and right half cover because of camber line reducing, the left and right half of propons is rotated with driving casing, forms front-wheel drive.
Before activation when wheel drive, when the vehicle turns to the left, right side wheels faster rotational speed and form right axle shaft cover and oppositely drive the driven roller on right side to move bottom the recess of arc, under opening the effect of spring outside, right drive roller departs from right axle shaft cover, then right side wheels is free to roll with higher rotating speed, realizes surmounting differential function.When vehicle right side wheel-slip is unsettled, the rolling resistance moment suffered by left side wheel increases, and left half axle is overlapped locking and obtains tighter by the driven roller in left side, then driving casing drives left half axle cover, interlock left half axle rotates, and drives left side wheel to roll with larger driving torque, realizes the sliding function of self-locking limit.When vehicle is turned right or left side wheel is skidded unsettled, similar to above-mentioned.
The beneficial effects of the utility model are:
1, when vehicle runs into abrupt slope or muddy wet-skid road surface, front-wheel drive can be started by making adhesive electromagnetic coil be energized, for vehicle provides more earth-grasping force, improving trafficability;
2, novel structure, volume is little, compared with open differential, not only there is differential action, and the change of condition and running resistance can be adhered to according to both sides wheel, redistribute driving torque, when single wheel skids, opposite side driving wheel can obtain larger driving torque, realizes self-locking and drives, thus improve the hauling ability of vehicle, improve trafficability.
