Double screwing direction screw real-time limited slip differential and vehicle with the same

Abstract

The invention discloses a double screwing direction screw real-time limited slip differential and a vehicle with the same. The double screwing direction screw real-time limited slip differential comprises a housing (1), a main retarder driven gear (2) arranged on the housing (1) and two screws (4) arranged in an inner cavity of the housing (1) and meshed with each other, wherein spiral teeth on the left half segment and the right half segment of each screw (4) are identical in group number and different in screwing direction, and the spiral teeth of the two screws (4) are interlocked when the two screws (4) are meshed with each other. The double screwing direction screw real-time limited slip differential further comprises half shafts (3) which are arranged at the left end and the right end of the housing (1) and connected with the screws (4) in transmission mode, wherein central axes of the half shafts (3) which are respectively located on the left side and the right side are arranged in coaxial mode. The vehicle is provided with the above double screwing direction screw real-time limited slip differential. The double screwing direction screw real-time limited slip differential is of pure mechanical structure, prevents skids in real time, does not delay in response, is simple in structure and low in cost, not only can be used for differential velocity among wheels, but also can be used for inter-axle differential velocity, is suitable for various vehicles of cars, trucks, military vehicles and the like, and obviously develops performance when used on cross country vehicles.

Description

technical field [0001] The invention relates to a dual-rotation screw real-time limited-slip differential and a vehicle with the differential, belonging to the technical field of vehicles. Background technique [0002] As an important part of the vehicle drive axle, the differential can ensure the normal turning of the driving vehicle and improve the passability of the vehicle in various complex road conditions. [0003] The existing differentials on the market can be divided into two types: non-limited-slip differentials and limited-slip differentials according to their functions. The non-limited-slip differential, that is, the traditional cross-axle differential, is limited to vehicles running on good roads that are not ice, snow or muddy due to its "differential speed without differential force". With the high-performance limited-slip differential With the emergence and development of differential gears, this type of differential gear is bound to be eliminated by the mar...

AI Technical Summary

Problems solved by technology

But at present, the high-performance limited-slip differential market is still dominated or even monopolized by companies from the United States, Germany, Japan and other countries. Such products mainly include Torsen differentials, Eaton differentials and electronic locking differentials, and The current limited-slip differentials are complex in structure, high in processing costs, and difficult to manufacture. Therefore, the core technology of limited-slip differentials in our country is almost blank, resulting in most vehicles in our country still using non-limited-slip differentials. Such technology Monopoly seriously restricts the development of my country's automobile industry
