People hope that the cross-country and difficulty-escaping ability of the automobile is strong besides the intelligent and networking requirements on the automobile, the requirement is met, and the four-wheel drive technology is involved, wherein the longitudinal four-wheel drive is a main structural form.
The longitudinal four-wheel drive power transmission line is an engine-transmission-transfer case, then the power is divided into two paths, one path is transmitted to the front wheel through the front transmission shaft-front main reducing-driving shaft, and the other path is transmitted to the rear wheel through the rear transmission shaft-rear main reducing-driving shaft. The front main reducer is arranged on one side of the power assembly, and two solutions are provided for transmitting power to the other side of the power assembly: one is to raise the power assembly, the driving shaft intermediate shaft passes through the lower part of the power assembly, and the other is to make the engine oil pan into a cavity structure, and the driving shaft intermediate shaft passes through the cavity structure of the oil pan (cylinder penetrating structure for short).
For off-road vehicles, the vehicle body height is high, the engine compartment space is large, and the first scheme can be adopted; however, for urban SUVs and cars, the engine compartment space is small due to the low height of the vehicle body, and a second solution, namely a through-cylinder structure, is needed. Because road conditions are better and better, requirements of people on vehicle smoothness, NVH and the like are continuously improved, urban SUVs and cars are more and more popular, at present, a cylinder penetrating structure is mainly applied to a longitudinally-arranged four-wheel drive vehicle type, and the occupation ratio can be stably improved along with the time.

During practical application, when the driving shaft intermediate shaft passes through the oil pan, the intermediate shaft bearing is exposed in the environment, the two sides are not protected in a sealing mode, and when a vehicle wades with water, the bearing is easy to enter water. In addition, water is easy to be stored in a cavity formed by the bearing and the oil pan shell, and the bearing is easy to cause abnormal sound and even failure due to long-time muddy water soaking; in addition, the both ends of the stepped shaft penetrating pipe and the press-fitting holes on the two sides of the oil pan are sealed through interference fit, and the stepped shaft penetrating pipe and the oil pan are different in structural wall thickness, so that the problem of leakage easily occurs under individual conditions due to different thermal expansion deformation.
The prior art also discloses a split type front drive axle assembly of running through the oil pan structure, and the main reducer assembly and the inner half axle assembly in the front drive axle assembly are connected on the engine oil pan to become a whole, have cancelled the suspension structure of solitary front drive axle assembly, solve the narrow and small problem in front axle assembly arrangement space effectively. In practical application, when a vehicle is involved with muddy water, particularly when the vehicle is trapped by muddy water, the muddy water enters an oil pan cavity from a gap between a bearing outer ring and an inner half shaft assembly bearing seat and a gap between an inner half shaft assembly and an oil pan installation surface, and can be slowly discharged for a long time, the muddy water flows to a bearing oil seal leftwards in the process, and flows to a front drive axle oil seal rightwards, a long-time muddy water soaking working scene is formed, the service life of a sealing system can be shortened, in addition, the sealing structure form and key performance parameters of a bearing are not explicitly provided in the prior art, and the sealing and the service life of the system can be influenced.
The prior art also discloses a final drive with a transition shaft: the reducer comprises a reducer main body and a transition shaft; the speed reducer main body comprises a half axle gear and an oil seal, and a connecting cavity is formed between the half axle gear and the oil seal; one end of the transition shaft penetrates through a connecting cavity on one side of the speed reducer main body, which is close to an engine oil pan, and is connected with the half-axle gear, and the other end of the transition shaft penetrates through an oil seal in the speed reducer main body and is connected with a driving shaft; the outer circular surface of the end part of the transition shaft connected with the half shaft gear is provided with an external spline which is connected with the half shaft gear; the inner circular surface of the end part of the transition shaft connected with the driving shaft is provided with an inner spline which is connected with the driving shaft, and the driving shaft part is arranged in the transition shaft.
