The automobile between-wheel differential mechanism assembly with the locking mechanism comprises a large differential mechanism shell, a small differential mechanism shell, a sliding meshing sleeve and a shifting fork, wherein the shifting fork is connected with an annular slot in the tail part of the sliding meshing sleeve; the automobile between-wheel differential mechanism assembly is characterized in that an outer spline is arranged on the outer wall of the front end part of the sliding meshing sleeve; an inner spline is arranged on the inner wall of a semiaxis via hole of the large differential mechanism shell. When a differential mechanism needs to be locked, the shifting fork drives the sliding meshing sleeve to move on a semiaxis, and the outer spline on the sliding meshing sleeve is meshed with the inner spline on the large differential mechanism shell. Preferably, the inner spline is arranged at the middle part of the semiaxis via hole of the large differential mechanism shell; the inner walls of via holes in two ends of the inner spline are smooth inner walls.
Description
Technical field
The present invention relates to a kind of automobile differential structure, particularly differential assembly between a kind of car-wheel with locking mechanism.
Background technique
Traditional automobile-used wheel edge deceleration driving axle differential assembly generally includes large and small differential carrier (usually, large differential carrier is provided with adpting flange, for being connected with by dynamic bevel gear, or large differential carrier is directly with one-body molded by dynamic bevel gear), fixed engagement cover, slip engaging sleeve and shift fork.Fixed engagement cover is connected with large differential carrier, to be overlapped and engages, thus realize the locking of differential assembly by fork controls slip engaging sleeve with fixed engagement.The outer wall of existing slip engaging sleeve and fixed engagement cover is equipped with can intermeshing inverted trapezoidal toothing, adopt this kind of structure, slip engaging sleeve engages level and smooth not between overlapping with fixed engagement, and need to be equipped with the larger cylinder of ouput force and run to control shift fork, not only cost is higher and take up room larger.In addition owing to processing inverted trapezoidal toothing on two engaging sleeve outer walls, in order to ensure enough engaging forces and bulk strength, need the entire outer diameter of engaging sleeve very large, the large differential carrier junction surface external diameter coordinated with it is also larger, cause bevel housing inner space compact, main reducing gear total quality is larger.Under the overall background advocating vehicle energy saving loss of weight, the differential assembly competitive ability of this kind of band differential lock structure is not high, in the urgent need to improving.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of differential assembly of band differential-speed lock mechanism of new structure, not only locking is more steadily reliable, and effectively can alleviate total quality, saves production cost.
In order to solve the problem, differential assembly between the car-wheel of this kind of band differential lock structure, comprise: large differential carrier, little differential carrier, slip engaging sleeve and shift fork, shift fork is connected with the circular groove of slip engaging sleeve afterbody, it is characterized in that: the front end outer wall of described slip engaging sleeve is provided with external splines, the semiaxis via hole inwall of described large differential carrier is provided with internal spline; When needs locking differential, shift fork drives slip engaging sleeve to move on semiaxis, and the external splines on slip engaging sleeve engages with the internal spline on large differential carrier.
Preferably, described internal spline is arranged on the middle part of the semiaxis via hole of large differential carrier, and the via hole inwall at these internal spline two ends is smooth inner wall.
More preferably, described internal spline and external splines are involute splines; The width of described internal spline is 15mm ~ 25mm, and internal diameter is 55mm ~ 100mm; Described external splines external diameter is 55mm ~ 100mm.
The invention has the beneficial effects as follows: by adopting this kind of structure, when needs locking differential, shift fork drives slip engaging sleeve to move on semiaxis, and the external splines on slip engaging sleeve engages with the internal spline on large differential carrier, realizes differential mechanism locking.This structure can ensure enough engaging forces and bulk strength, and engagement effect is more smooth-going, entire outer diameter and the large differential carrier junction surface external diameter of engaging sleeve do not need very large, and eliminate fixed engagement cover, greatly save bevel housing inner space, alleviate main reducing gear total quality.But also the less cylinder of output power can be selected to control shift fork, can cost-saving and volume further.
Accompanying drawing explanation
Fig. 1 be band differential lock structure of the present invention car-wheel between the overall structure schematic diagram of differential assembly;
Fig. 2 is the sectional structure schematic diagram of the slip engaging sleeve in the present invention;
Fig. 3 is the sectional structure schematic diagram of the large differential carrier in the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, differential assembly between the car-wheel of this kind of band differential lock structure, comprise: large differential carrier 2(is with adpting flange or band by half shell of dynamic bevel gear), little differential carrier 1, be arranged on slip engaging sleeve 3 on semiaxis 4 and shift fork 5, shift fork one end is connected with cylinder output shaft, the other end is connected with the circular groove of slip engaging sleeve afterbody, differential gear is arranged in differential casing, being engaged with the drive bevel gear on main shaft by dynamic bevel gear on differential mechanism.
Composition graphs 1 and Fig. 2, the outer wall of the front end (for the circular groove of its afterbody) of this slip engaging sleeve 3 is provided with a circle external splines 31, and this external splines is preferably involute splines, and described external splines external diameter is 55mm ~ 100mm.
Composition graphs 1 and Fig. 3, the semiaxis via hole inwall of this large differential carrier 2 is provided with a circle internal spline 21.This internal spline also can be preferably involute splines.In addition; at this semiaxis via hole inwall, one section of internal spline is only set; this internal spline is arranged on the general medium position of axis along semiaxis via hole; and the via hole inwall at its two ends is still smooth inner wall; the side smooth inner wall of internal spline is used for arranging differential gear tooth root; the smooth inner wall of opposite side is used for pre-seting slip engaging sleeve, thus plays the effect of protection engaging sleeve, and engagement process is more smooth-going.By repeatedly testing also according to actual needs, the width of this spline is preferably 15mm ~ 25mm, and its internal diameter is preferably 55mm ~ 100mm.
By adopting this kind of structure, when needs locking differential, shift fork drives slip engaging sleeve to move on semiaxis, and the external splines on slip engaging sleeve engages with the internal spline on large differential carrier, realizes differential mechanism locking.This structure can ensure enough engaging forces and bulk strength, and engagement effect is more smooth-going, entire outer diameter and the large differential carrier junction surface external diameter of engaging sleeve do not need very large, and eliminate fixed engagement cover, greatly save bevel housing inner space, alleviate main reducing gear total quality.But also the less cylinder of output power can be selected to control shift fork, can cost-saving and volume further.
It should be noted that; embodiment is only explanation to technical solution of the present invention and explanation; should not be understood as the restriction to technical solution of the present invention, any employing technological scheme of the present invention and only do local change, must fall within the scope of protection of the present invention.
