Abstract
The utility model discloses a front axle of a four-wheel driven car. The utility model has the technical proposal that a transfer case is arranged on the front axle, and a front axle differential is arranged in the transfer case. The transfer case of the utility model is arranged on the front axle, the front axle differential is arranged in the transfer case, and thus, transmission system components are reduced in order to reduce the weight of the entire car. Mechanical friction is decreased in order to reduce power loss. The utility model also has the advantages of compact structure and simple manufacture technology. The front axle structure of the four-wheel driven car can use independent suspension, and the riding comfort of the four-wheel driven car is increased.
Description
Technical field
The utility model relates to 4-wheel driven car transmission system manufacturing technology field, relates to a kind of propons of 4-wheel driven car in particular.
Background technology
Common 4-wheel driven car, auxiliary gear box is what to separate with propons, by transmission shaft moment of torsion is passed to auxiliary gear box by driving engine, through by another transmission shaft moment of torsion being sent to propons and back axle again after the auxiliary gear box secondary torque distribution, realizes four wheel drive.Shortcoming is that Parts for Power Train is more, and complete vehicle quality increases; Mechanical friction is big, and loss in efficiency increases; Structure is not compact, and manufacturing process is poor; This structure 4 propons of driving adopts dependent suspension usually, and the 4-wheel driven car travelling comfort reduces.
Summary of the invention
Technical problem to be solved in the utility model provides a kind ofly can reduce the transmission system parts, reduce mechanical friction, make the propons of 4-wheel driven car chassis drive mechanism compactness.
Technical solution of the present utility model is that auxiliary gear box is arranged on the propons, and front axle differential is arranged in the auxiliary gear box.
Above-mentioned propons fwd driving engine is a lateral arrangement.
Above-mentioned front axle differential is connected with the interior hub of the viscous coupling in being arranged on auxiliary gear box.
The shell of above-mentioned viscous coupling is connected with the gear ring that is arranged on a pair of skew bevel gear in the auxiliary gear box, and the interior hub of viscous coupling and shell while are connected with interaxle differential in being arranged on change speed gear box.It is that transmission of power is arrived front axle differential that interior hub connects interaxle differential, and it is to rear driving axle with transmission of power that shell connects interaxle differential.
The utility model is owing to be arranged on auxiliary gear box on the propons, and front axle differential is arranged in the auxiliary gear box.Therefore reduce Parts for Power Train, thereby reduced complete vehicle quality; Reduce mechanical friction, thereby reduced loss in efficiency; And compact conformation, manufacturing process is simple; Bridge construction can be adopted independent suspension before this 4-wheel driven car, and the 4-wheel driven car travelling comfort improves.
