Abstract
A kind of lightweight differential mechanism, including upper cone bearing, axle shaft gear and gasket, planetary gear shaft, bolt, lower cone bearing, master subtract gear, planetary gear and gasket, differential casing, it is characterised in that：It further include gasket baffle, utilize the shape and structure of gasket baffle bending, form fixed structure, master is subtracted gear, differential casing and gasket baffle by bolt to fix, axle shaft gear and gasket and planetary gear and gasket are fixed on differential casing by axis of cone bearing outer-ring with upper cone bearing and lower cone bearing cooperation positioning and gear box casing mould assembling, planetary gear shaft.While the utility model realizes that rotating speed, torque transmit, the weight of itself is reduced, in the case of keeping gearbox-gear constant, vehicle has better economic stimuli.
Description
Technical field
The utility model is related to a kind of automotive transmission differential mechanisms.
Background technology
Important component of the gearbox as vehicle, the power for engine transmit and change transmission ratio, expands driving wheel
The variation range of torque and rotating speed makes engine under the high fuel-efficient operating mode of power to adapt to the driving conditions often changed
Work.Differential mechanism is the critical component of gearbox, is used for the distribution of rotating speed, and left and right semiaxis vehicle is realized by " minimum stream power "
The speed difference of wheel.Differential assembly structure includes mainly following components：Differential casing, axle shaft gear and gasket, row
Star gear and gasket, planetary gear shaft, plate gear, cone bearing, master subtract gear, bolt, and wherein cone bearing plays a supportive role, and holds
By load axially and radially, planetary gear shaft support planetary gears and axle shaft gear, plate gear fix planetary gear shaft and difference
Fast device shell.Differential assembly accounts for the 11.5% of gearbox weight at present, is the break through direction for realizing gearbox light-weight design.
Invention content
The purpose of this utility model is to provide a kind of lightweight differential mechanisms, overcome former differential mechanism plate gear fixed weight
Weight, disadvantage of high cost.
A kind of lightweight differential mechanism, including upper cone bearing, axle shaft gear and gasket, planetary gear shaft, bolt, the lower axis of cone
It holds, lead and subtract gear, planetary gear and gasket, differential casing, it is characterised in that：Further include gasket baffle, utilizes gasket baffle
The shape and structure of bending forms fixed structure, and master is subtracted gear, differential casing and gasket baffle by bolt to fix, outside cone bearing
Circle and upper cone bearing and lower cone bearing cooperation positioning and gear box casing mould assembling, planetary gear shaft is by axle shaft gear and gasket and row
Star gear and gasket are fixed on differential casing.
A kind of lightweight differential mechanism, it is characterised in that：The bending part that 90 ° of gasket baffle, which is equipped with, to be reinforced supporting, round nose
There is ball-type boss in the middle part of plate, ball-type boss and planetary gear shaft point contact, the clearance fit of the gasket baffle of symmetrical distribution,
Limit the displacement of its axial float.
The utility model has the advantages that：While the utility model realizes that rotating speed, torque transmit, the weight of itself is reduced
Amount, in the case of keeping gearbox-gear constant, vehicle has better economic stimuli.The utility model is in original revolution speed sensing
After device speed measuring function transposing to the wheel speed sensing of vehicle, the mechanism of bolt is added to substitute on plate gear fixed function gasket baffle,
To realize light-weighted design.

Baffle 7 is fixed, axis of cone bearing outer-ring and upper cone bearing 1 and lower cone bearing 5 cooperation positioning and gear box casing mould assembling, planetary gear shaft
3 are fixed on axle shaft gear and gasket 2 and planetary gear and gasket 8 on differential casing 9.
Utility model works principle：Using planetary gear shaft 3 by axle shaft gear and gasket 2 and planetary gear and gasket 8
It is fixed on differential casing 9.Gasket baffle 7 is symmetrical with respect to planetary gear shaft 3, is tightened bolt 4 using wrest fixing spanner
Fixed master subtracts gear 6, gasket baffle 7 and differential casing 9.Upper cone bearing 1 and lower cone bearing 5 are fitted in differential with pressing machine
On device shell 9.When gearbox is run, the main gear 6 that subtracts drives differential casing 9 to rotate together, the spherical boss of gasket baffle 7
73 withstand planetary gear shaft 3, limit its play.Finally, by axle shaft gear and gasket 2 and half axis connection of vehicle, output turns
Speed and torque are to vehicle.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, make several equivalent substitute or obvious modifications without departing from the concept of the premise utility, and performance or
Purposes is identical, then shall be regarded as belonging to the protection domain that claims that the utility model is submitted determine.
