The utility model discloses a rear axle differential device and an energy-saving vehicle using the differential device. The rear axle differential device includes a power device for rotating an axle assembled on a vehicle frame and driving the axle to rotate. Wheels are respectively installed at the two ends, and an overrunning clutch is respectively installed between the two wheels and the axle shaft. The inner ring of the overrunning clutch is coaxially fixedly connected with the axle shaft respectively, and the outer ring is respectively coaxially fixedly connected with the respective corresponding wheels. The rear axle differential device of this structure can meet the requirements of wheel rotation and inner and outer wheel differential speed when turning, and compared with the prior art, the size and quality of the overrunning clutch are obviously smaller than the size and quality of the differential, and it is also The utility model can meet the lightweight requirement of the energy-saving vehicle, and has a simple structure.
Description
Technical field
The utility model relates to a kind of energy-conservation car, is specifically related to the back axle differential gear of energy-conservation car, belongs to automotive field.
Background technology
Two-wheel drives automobile axle differential gear generally is housed, and differential gear can satisfy the requirement of inside and outside wheel differential when turning.Traditional differential gear adopts diff mostly; But along with the development of automotive energy-saving emission-reducing, the appearance of especially energy-conservation car requires the energy-conservation car under the premise that security is guaranteed can expendable weight; To improve driving efficiency and energy savings consumption; But common diff size and quality are excessive, can not satisfy the lightness requirement of energy-conservation car, and design and installation simultaneously is also comparatively complicated.
The utility model content
The purpose of the utility model provides a kind of automobile axle differential gear that can satisfy energy-conservation car lightness requirement, and the energy-conservation car that uses this differential gear is provided simultaneously.
The back axle differential gear of the utility model adopts following technical scheme: a kind of back axle differential gear; Comprise and be used to rotate the engine installation that the axletree that is assemblied on the vehicle frame and drive axle are rotated; The two ends of axletree are separately installed with wheel; Be separately installed with overriding clutch between two wheels and the axletree, the inner ring of overriding clutch coaxially is connected with axletree respectively, self-corresponding wheel is coaxial is connected with each respectively in the outer ring.
The energy-conservation car of the utility model adopts following technical scheme: a kind of energy-conservation car; Comprise vehicle frame and be installed in the back axle differential gear on the vehicle frame; Said back axle differential gear comprises and rotates the engine installation that the axletree be assemblied on the vehicle frame and drive axle are rotated; The two ends of axletree are separately installed with wheel, are separately installed with overriding clutch between two wheels and the axletree, and the inner ring of overriding clutch coaxially is connected with axletree respectively, self-corresponding wheel is coaxial is connected with each respectively in the outer ring.
Adopt the back axle differential gear of said structure and use the energy-conservation car of this device, owing to be separately installed with overriding clutch between axletree and the wheel, the inner ring of overriding clutch and axletree be coaxial to be connected, the outer ring is connected with wheel is coaxial; During power transmission, power is passed to the inner ring of overriding clutch through axletree, and the relative outer ring of inner ring all has the trend that surmounts all the time; Therefore power is passed to the outer ring again through inner ring, thereby realizes the rotation of wheel, when turning; The rotating speed of inboard wheel is less than the rotating speed of outboard wheels; And the rotating speed of axletree is less than the rotating speed of outboard wheels, greater than the rotating speed of inboard wheel, and the cooresponding overriding clutch of inboard wheel can guarantee that inner ring all has the trend that surmounts all the time to the outer ring, and the cooresponding overriding clutch of outboard wheels can guarantee that the relative inner ring in outer ring all has the trend that surmounts all the time; Therefore; The back axle differential gear of this structure can satisfy wheel and the inside and outside wheel differential requirement when turning, and relative to existing technologies, the size of overriding clutch and quality are significantly less than the size and the quality of diff; Also can satisfy the lightness requirement of energy-conservation car, and simple in structure.
Description of drawings
Fig. 1 is the example structure scheme drawing of the back axle differential gear of the utility model.
The specific embodiment
The embodiment of the back axle differential gear of the utility model: as shown in Figure 1; Comprise and be used to rotate the axletree 6 that is assemblied on the vehicle frame 3; Axletree 6 is in transmission connection through gear cluster 5 and engine installation 4; The two ends of axletree 6 are separately installed with between 1, two wheel 1 of wheel and the axletree 6 and are separately installed with overriding clutch, the inner ring 7 of two overriding clutchs coaxially is connected with axletree 6 respectively, outer ring 2 respectively with each self-corresponding wheel 1 coaxial being connected.
When power transmission; Engine installation 4 drives axletree 6 through gear cluster 5 and on vehicle frame 3, rotates; Power is passed to the inner ring 7 of overriding clutch through axletree 6, and the trend that inner ring 7 relative outer rings 2 all have rotating speed to surmount all the time is so overriding clutch inner ring 7 combines with outer ring 2; Power is passed to outer ring 2 through the inner ring 7 of overriding clutch, passes to wheel 1 again and realizes power transmission.In the turning process; The rotating speed of inboard wheel is less than the outboard wheels rotating speed; And the rotating speed of axletree 6 is less than the rotating speed of the outboard wheels rotating speed greater than inboard wheel, and power only can be passed to inboard wheel through axletree 6, and the rotating speed that guarantees outboard wheels is all the time greater than the rotating speed of inboard wheel.
The embodiment of the energy-conservation car of the utility model: comprise vehicle frame and be installed in the back axle differential gear on the vehicle frame, as shown in Figure 1, the structure of back axle differential gear is consistent with the structure of the back axle differential gear of the foregoing description, and its content repeats no more at this.
