Problems solved by technology

Traditional differential devices mostly use differentials, but with the development of energy-saving and emission-reduction vehicles, especially the emergence of energy-saving vehicles, energy-saving vehicles are required to reduce weight under the premise of ensuring safety, so as to improve transmission efficiency and save energy consumption. However, the size and mass of common differentials are too large to meet the lightweight requirements of energy-saving vehicles, and the design and installation are also more complicated

Embodiment Construction

[0008] The embodiment of rear axle differential device of the present invention: as figure 1 As shown, it includes an axle 6 that is used to rotate and assemble on the vehicle frame 3. The axle 6 is connected to the power unit 4 through a gear set 5. The two ends of the axle 6 are respectively equipped with wheels 1. Between the two wheels 1 and the axle 6 Overrunning clutches are respectively installed, and the inner rings 7 of the two overrunning clutches are coaxially fixedly connected with the axle shaft 6 respectively, and the outer rings 2 are respectively coaxially fixedly connected with the corresponding wheels 1 respectively.

[0009] During power transmission, the power unit 4 drives the axle 6 to rotate on the vehicle frame 3 through the gear set 5, and the power is transmitted to the inner ring 7 of the overrunning clutch through the axle 6. The inner ring 7 always has a tendency to exceed the speed of the outer ring 2 relative to the outer ring 2. Therefore, the i...

Abstract

The invention discloses a rear axle differential device and an energy-saving vehicle employing the same. The rear axle differential device comprises an axle which is used to be assembled on a frame in a rotating mode and a power device for driving the axle to rotate, wherein the two ends of the axle are provided with a wheel respectively; the space between one wheel and the axle as well as the space between the other wheel and the axle are provided with an overrunning clutch respectively; and inner rings of the overrunning clutches are coaxially and fixedly connected with the axle respectively, and outer rings of the overrunning clutches are coaxially and fixedly connected with corresponding wheels respectively. The rear axle differential device with the structure can meet the requirement of differential of inner and outer wheels in the wheel rotating process and the turning process; and compared with the prior art, the device has the advantages that the sizes and the mass of the overrunning clutches are obviously less than those of a differential, the requirement of lightening energy-saving vehicles can be met, and the device has a simple structure.

Description

technical field [0001] The invention relates to an energy-saving vehicle, in particular to a rear axle differential device of the energy-saving vehicle, which belongs to the field of automobiles. Background technique [0002] The rear axle of a two-wheel drive vehicle is generally equipped with a differential device, which can meet the requirements of the differential speed of the inner and outer wheels when turning. Traditional differential devices mostly use differentials, but with the development of energy-saving and emission-reduction vehicles, especially the emergence of energy-saving vehicles, energy-saving vehicles are required to reduce weight under the premise of ensuring safety, so as to improve transmission efficiency and save energy consumption. However, the size and mass of common differentials are too large to meet the lightweight requirements of energy-saving vehicles, and the design and installation are also more complicated.
