Embodiment Construction

[0043] The vehicle differential comprises a drive housing 1 in which there are two harmonic gear reducers 2 and 3 corresponding coaxially on rolling bodies 4 (balls, rollers). The crown gear 5 of one harmonic drive reducer 2 and the spacer 6 of the other harmonic drive reducer 3 are integrally formed on the drive shell 1, and one harmonic drive reducer 2 The isolator 7 is integrated with the crown gear 8 of another harmonic drive reducer 3 .

[0044] During the linear motion of the vehicle on a good road, rotation is provided by the main housing part (which is connected to the crown gear of one harmonic drive reducer and the spacer of the other harmonic drive reducer) through the eccentric side gear The balls, the rollers, which the elements contact, are transmitted to the half-shafts of the vehicle and further to the drive wheels to give them equal angular velocity.

[0045] When a vehicle is cornering or one of the driven wheels is on an uneven road surface, the two wheels ...

Abstract

The invention relates to the automobile industry and can be used in the differential driving gears for wheeled vehicles with a possibility of automatically locking wheels. The technical result consists in eliminating the above-mentioned inconveniences, namely, by simplifying the structural design and increasing the strength and reliability. The technical result is achieved in that the vehicle differential comprising a drive case, in which case two planetary gear reducers are coaxially accommodated, is also provided with harmonic drive reducers based on rolling bodies (balls, rollers), in that the crown of one of the harmonic drive reducers and the separator of the other harmonic drive reducer are formed in an integral manner with the drive case, and the separator of one of the harmonic drive reducers and the crown of the other harmonic drive reducer are formed in one piece.

Description

【Technical field】 [0001] The present invention relates to the automotive industry and can be used in differential drive gears for wheeled vehicles having an automatic wheel locking capability. 【Background technique】 [0002] The strength and durability of the differential are particularly required when the entire torque is supplied from the engine to the drive wheels through the differential. [0003] Russian Patent No. 2044942 discloses a vehicle differential, which includes a housing with side gears (side gears) respectively located on two coaxial half-shafts (half-shafts) and mutually offset (offset) , one of the side gears is connected to the housing and is arranged to rotate around a shaft fixed to the half shaft, and the other side gear is engaged with a crown fixed in the housing. The other side gear fixed on the half shaft is driven by the internal ring gear to mesh with the side gear. The axes of the two gears are located on different sides of the central line of ...
