Abstract

The invention relates to a direct through type single-stage reduction drive axle. The direct through type single-stage reduction drive axle comprises an axle housing, wheel hubs, a brake and a direct through type main reducer. A wheel differential mechanism is arranged in the direct through type main reducer, one end of a left-half shaft and one end of a right-half shaft which are arranged in the axle housing are respectively matched and connected with a left-half shaft gear and a right-half shaft gear in the wheel differential mechanism, the other end of the left-half shaft and the other end of the right-half shaft are matched and connected with wheel hubs arranged at the left end and the right end of the axle housing, and the wheel differential mechanism is connected with a passive double curved surface gear. The wheel differential mechanism is arranged in the direct through type main reducer, a through shaft is arranged above and perpendicular to the left-half shaft, one end of the through shaft is matched and connected with the axle housing, the other end of the through shaft is matched and connected with a first bevel gear, one end of a shaft barrel integrated with an active double curved surface gear is matched and connected with a second bevel gear arranged in the wheel differential mechanism, and the active double curved surface gear is a right-handed rotation gear and meshed with the passive double curved surface gear arranged on the wheel differential mechanism. The direct through type single-stage reduction drive axle is high in transmission efficiency and good in economical efficiency and passing ability.

Description

technical field [0001] The invention relates to heavy-duty automobile components, in particular to a direct through-type single-stage deceleration drive axle used for multi-connection drive axles in multi-axle (three-axle and more than three-axle) heavy-duty automobiles. Background technique [0002] At present, in the design and manufacture of domestic multi-axle heavy-duty vehicles, in order to simplify the structure, simplify the arrangement of the transmission shaft, make the components common and facilitate the formation of series products, through-type drive axles are often used. The drive shafts of the two drive axles are connected in series, and the drive shaft passes through the drive axle that is closer to the transmission or transfer box to the other drive axle. In this arrangement, the drive shaft must pass through the drive axle. However, this type of drive axle is called a through drive axle. Domestic single-stage reduction through-type drive axles are usually...
