Abstract
The utility model relates to a steering drive axle of off-road vehicles, which provides a through-type second steering drive axle. The utility model is mainly composed of a bridge case, an inter-axle differential, an oil thrower wheel, a primary gearbox, an axle casing, a through shaft, an inter-wheel differential, a hub reduction gear and a haft shaft. The inter-wheel differential and the oil thrower wheel are mounted in the bridge case, and the through shaft passes through the bridge case and a primary gearbox casing to a first axle. The primary gearbox and the inter-wheel differential are respectively mounted in the primary gearbox casing and the axle casing, the inter-axle differential is connected with the through shaft, and the primary gearbox is connected with the through shaft via a gear in the bridge case. The primary gearbox is connected with the inter-wheel differential, the haft shaft, and the hub reduction gear in turn. The utility model can obtain a big drive ratio through two-step speed reduction, thereby extending the distance between the axle casing and the ground and improving the cross-country capacity of vehicles.
Description
(1) technical field
The utility model relates to the steering drive axle on the cross country car.
(2) background technology
On the cross country car of multi axle drives such as 8 * 8 and 10 * 10, second steering drive axle is the assembly of a key, its function except satisfy turning to of self require and drive require, also need part-time case is passed the torque that come dispensing first steering drive axle in proportion.Present cross-country car second steering drive axle has only the one-level deceleration transmission, and transmitting ratio is big, and overhead the gap is less at the axle housing middle part, makes the off-road capability of automobile poor.
(3) summary of the invention
The utility model is at the deficiencies in the prior art, and overhead big through second steering drive axle of cross country car in gap of a kind of simple in structure, axle housing is provided.
The utility model adopts following solution: this through second steering drive axle is by the gap bridge case, interaxle differential, main reduction gear, axle housing, thru shaft, inter-wheel differential, lubricating disc, wheel reduction gear and semiaxis are formed, interaxle differential and lubricating disc are installed in the gap bridge case, thru shaft passes the gap bridge case and final drive casing leads to first bridge, main reduction gear and inter-wheel differential are installed in respectively in final drive casing and the axle housing, interaxle differential and thru shaft link together, main reduction gear is connected main reduction gear and inter-wheel differential with thru shaft by the gear in the gap bridge case, semiaxis and wheel reduction gear are connected successively.
During use, power is given first, second steering drive axle by interaxle differential with power distribution from the input of input shaft flange.Wherein pass to the power of second steering drive axle and pass to semiaxis and wheel reduction gear, the drive wheels rotation through main reduction gear, inter-wheel differential.Second drive axle can obtain big final ratio by main reduction gear and wheel reduction gear double reduction, and the axle housing ground Clearance is increased, and can reach 320mm, has improved the off-road capability of automobile.
(4) description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of the utility model wheel reduction gear.
Wherein: 1, differential 7, input shaft flange 8, final drive casing 9, lubricating disc 10, semiaxis 11, universal-joint 12, wheel reduction gear between gap bridge case 2, interaxle differential 3, main reduction gear 4, axle housing 5, thru shaft 6, wheel
(5) specific embodiment
Fig. 1 and Fig. 2 have provided structural representation of the present utility model.The utility model mainly is made up of gap bridge case 1, interaxle differential 2, lubricating disc 9, main reduction gear 3, axle housing 4, thru shaft 5, inter-wheel differential 6, wheel reduction gear 12 and semiaxis 10.During use, power is given first, second steering drive axle by interaxle differential 2 with power distribution from 7 inputs of input shaft flange.Wherein pass to the power of second steering drive axle and pass to semiaxis 10, pass to wheel reduction gear 12 by universal-joint 11 again and rotate with drive wheels through main reduction gear 3, inter-wheel differential 6.Ad hoc in the gap bridge case in respect of lubricating disc, force lubrication by atomization, guaranteed the lubricated of interaxle differential.
The utility model second steering drive axle is a double reduction, and wherein first order transmitting ratio is determined by the spiral bevel gear pair of the main reduction gear that is arranged in axle housing central authorities, and second stage transmitting ratio is determined by the cylindrical planetary gear in the wheel reduction gear.Because first reduction ratio less (less than 3), therefore, overhead the gap is bigger at the axle housing middle part, reached 320mm, thereby can satisfy the off-highway requirement of automobile, second stage reduction ratio has only a kind of speed ratio, according to different operatings needs, by changing different bevel-gear pairs, can be combined into multiple big total reduction gear ratio with second stage speed ratio.In order to improve load-carrying capacity, driving axle housing adopts the integral cast steel structure.
Claims (1)
1. through second steering drive axle of cross country car, by the gap bridge case, interaxle differential, lubricating disc, main reduction gear, axle housing, thru shaft, inter-wheel differential, wheel reduction gear and semiaxis are formed, it is characterized in that: interaxle differential and lubricating disc are installed in the gap bridge case, thru shaft passes the gap bridge case and final drive casing leads to first bridge, main reduction gear and inter-wheel differential are installed in respectively in final drive casing and the axle housing, interaxle differential and thru shaft link together, main reduction gear is connected main reduction gear and inter-wheel differential with thru shaft by the gear in the gap bridge case, semiaxis and wheel reduction gear are connected successively.
