Abstract
The invention discloses a single-stage speed-reducing driving axle assembly. The technical scheme is as follows: the single-stage speed-reducing driving axle assembly comprises a main speed-reducing shell and semi-shafts, wherein the main speed-reducing shell and the semi-shafts are provided with an inter-wheel differential lock. The inter-wheel differential lock is mainly used for an inter-wheel differential and has the main effects of eliminating the speed difference between wheels at the left side and the right side, and maintaining synchronous rotation of the wheels. The single-stage speed-reducing driving axle assembly disclosed by the invention has the beneficial effects that the function is mainly used for bad roads such as slopes and mud roads; after the differential lock is closed under the bad roads, the left semi-shaft, the right semi-shaft and the differential form rigid connection, so that the wheels are prevented from slipping and the passing ability is improved.
Description
Technical field
The present invention is a kind of singl-reduction axle assembly, belongs to technical field of automobile parts.
Background technology
A domestic differential locking-device of taking turns is used for dual-ratio reduction drive axle at present, and singl-reduction axle mostly only adopts shaft space difference speed lock.And when vehicle climbing, or while getting bogged down in the mud, an only reliable differential locking-device locking inter-wheel differential of taking turns, improves the crossing ability of automobile.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of technical scheme of singl-reduction axle assembly is provided, this drive axle assembly has mated differential locking-device between wheel on the basis of shaft space difference speed lock, under Huai road, engage after differential locking-device, left and right half and diff form and are rigidly connected, avoid tyre skidding, improve crossing ability.
The present invention realizes by following technical measures: a kind of singl-reduction axle assembly, comprise main deceleration shell, semiaxis, and on described main deceleration shell and semiaxis, differential locking-device between wheel is installed.Between wheel, differential locking-device is mainly used in inter-wheel differential, and Main Function is to make left and right sides wheel there is no velocity contrast, keeps synchronously rotating.This function Main Function is in climbing, road Deng Huai road.
Concrete feature of the present invention also has, an above-mentioned differential locking-device of taking turns comprises inside and outside engaging sleeve, the shifting fork assembly with engaging tooth, described external toothing cover coordinates with shifting fork assembly and external toothing cover is connected with semiaxis by spline, and described interior engaging sleeve is structure as a whole with differential cover or is fixedly connected with.On end face, have the external toothing of soldered tooth to apply mechanically spline and be connected with differential cover with semiaxis, and interior engaging sleeve and differential cover adopt integrated design.After differential locking-device engages, engaging sleeve engages with differential cover, diff and semiaxis is connected into as a whole, the diff differential action that do not recur, and semiaxis becomes a rigidity axle drive shaft.
Beneficial effect of the present invention is: designed a kind of singl-reduction axle assembly with differential locking-device, this drive axle assembly has mated differential locking-device between wheel on the basis of shaft space difference speed lock, under Huai road, engage after differential locking-device, left and right half and diff form and are rigidly connected, avoid tyre skidding, improve crossing ability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention.
Wherein: 1. main deceleration shell, 2. semiaxis, 3. shifting fork assembly, 4. differential cover, 5. external toothing cover, 6. interior engaging sleeve, 7. spline.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, this programme is set forth.
As accompanying drawing, a kind of singl-reduction axle assembly, a kind of singl-reduction axle assembly, comprises main deceleration shell 1, semiaxis 2, on described main deceleration shell 1 and semiaxis 2, differential locking-device between wheel is installed.Between wheel, differential locking-device comprises inside and outside engaging sleeve 6,5, the shifting fork assembly 3 with engaging tooth, described external toothing cover 5 coordinates with shifting fork assembly 3 and external toothing cover 5 is connected with semiaxis 2 by spline 7, and described interior engaging sleeve 6 is structure as a whole or is fixedly connected with differential cover 4.
The present invention can pass through or adopt existing techniques in realizing without the technical characterictic of describing; do not repeat them here; certainly; above-mentioned explanation is not limitation of the present invention; the present invention is also not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present invention, also should belong to protection scope of the present invention.
Claims (2)
