Abstract
The utility model discloses a back bridge capable of lowering the chassis height of a four-wheel driven car, which comprises decelerator gears. The utility model is characterized in that the decelerator gears use a pair of hypoid gears. The field crossing performance of the utility model is secondary but the riding comfort is predominant for the leisure four-wheel driven car mainly running in a city. The utility model uses the hypoid gears to replace original straight bevel gears, and thus, the ground clearance of the car is reduced and the riding comfort of the four-wheel driven car is increased by the eccentric distance of gears under the condition that the height of the entire four-wheel driven car is not changed. In addition, the hypoid gears have stable operation and low working noise.
Description
Technical field
The utility model relates to 4-wheel driven car transmission system manufacturing technology field, relates to a kind of back axle that can reduce the 4-wheel driven car chassis height in particular.
Background technology
What the rear axle reductor gear of 4-wheel driven car adopted at present is spur bevel gear wheel, and under driving engine height unmodified situation, chassis height is fixing can not to be changed.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of under driving engine height unmodified situation, can reduce the back axle of 4-wheel driven car chassis height.
The utility model comprises reducer gear, it is characterized in that: what reducer gear adopted is a pair of skew bevel gear.
The gear wheel shaft of above-mentioned a pair of skew bevel gear is connected with another gear wheel shaft to skew bevel gear in being arranged on auxiliary gear box by a transmission shaft.
Above-mentioned another driven by gear ring the gear wheel shaft of skew bevel gear, and the gear ring viscous coupling shell interior with being arranged on auxiliary gear box is connected.
The interior hub of above-mentioned viscous coupling and shell simultaneously be arranged on change speed gear box in interaxle differential is connected, the interior hub front axle differential interior with being arranged on auxiliary gear box is connected.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.
For the leisure 4-wheel driven car that mainly travels in the city, its off-road capability is less important, and its travelling comfort is main.The utility model by the eccentric throw between gear, under 4-wheel driven car driving engine height unmodified situation, reduces the ground Clearance of automobile owing to adopt a pair of skew bevel gear to replace original spur bevel gear wheel, increases the travelling comfort of 4-wheel driven car.The skew bevel gear running is steady in addition, and operating noise is little.
