This application discloses a kind of lubrication systems of bridge case integrated gearbox system, transmission input shaft and motor input shaft including shell and installation in the housing, transmission input shaft is mounted in shell by transmission input shaft bearing, motor input shaft is mounted in shell by motor bearing of input shaft, and transmission input shaft is connected with motor input shaft by connector;Rotary rotary packing ring is equipped between shell and motor input shaft, rotary rotary packing ring can make the intracorporal lubricating oil of shell flow to connector.The utility model between transmission input shaft and motor input shaft by installing rotary rotary packing ring, the lubrication and cooling of connector are enhanced, the service life of connector is improved, simultaneously because gearbox, motor and drive axle are the integrated design, installation space is saved, is reduced costs.

Description

The lubrication system of bridge case integrated gearbox system
Technical field
The utility model relates to bridge case integrated gearbox systems, and in particular to a kind of lubrication of bridge case integrated gearbox system Structure.
Background technique
The exit time table of the Chinese conventional fuel oil car that begun one's study, the prospect of electric car are self-evident at present.It is electronic The design of automobile drive axle overall performance is served it is vital, existing bridge case integral structure make structure design more step up It gathers, saves space, while improving balance, promote the security performance of vehicle.
In existing vehicle technology, the coupling part between motor input shaft and transmission input shaft generallys use rouge Lubrication.Such as application No. is the utility model patents of CN2017216150972 to provide a kind of electricity of the input shaft with sealing function The input shaft end of motor-car reduction gearbox, including electric vehicle reduction gearbox, the electric vehicle reduction gearbox is equipped with an external splines, the outer flower Internal spline on the output end of key and driving motor is in mating connection, and the electric vehicle reduction gearbox further includes a sealing ring, described Input shaft is located at the external splines inner end edge and is additionally provided with an annular groove, and the sealing ring is sheathed on the annular groove.The technology A sealing ring is arranged by the external splines inner end edge in electric vehicle reduction box input shaft in scheme, connects in reduction gearbox with motor Afterwards, effective sealing can be formed at interior external splines counterface, prevents lubricating grease from flying out, while preventing foreign matter from entering At inside and outside spline fitted, increase the service life of interior external splines.But since the cooling heat spreading function of lubricating grease is poor, using lubrication Moment of friction when the equipment starting of rouge is bigger;Grease lubrication mode is easy to make the coupling part of bridge case integrated gearbox system to grind Damage.
In another example application No. is the utility applications of CN2017214489614 to disclose a kind of spline lubrication machine Structure, the head end that the external splines construction of motor shaft is corresponded in the axial direction of one axis of retarder is provided with and the gear lubricant of retarder connects The first logical oil duct, the end that the external splines construction of motor shaft is corresponded in the axial direction of one axis of retarder is provided with and retarder Gear lubricant connection the second oil duct;The spline lubrication mechanism that the utility model provides, can use the gear of retarder Lubricating oil lubricates spline, so that spline is in and lubricates in good working environment, reduce the degree of spline wear, improves power The working life of assembly;But there are complicated defects.
Summary of the invention
The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of lubrication of bridge case integrated gearbox system Structure, the lubrication system of the bridge case integrated gearbox system can enable the lubricating oil in bridge case integrated gearbox system lubricate Coupling part between cooling motor input shaft and transmission input shaft, to improve the service life of coupling part.
The technical solution that the utility model solves the problems, such as is: a kind of lubrication system of bridge case integrated gearbox system, special Sign is: including the transmission input shaft and motor input shaft of shell and installation in the housing, transmission input shaft passes through change Fast case bearing of input shaft is mounted in shell, and motor input shaft is mounted in shell by motor bearing of input shaft, and gearbox is defeated Enter axis and is connected with motor input shaft by connector;Rotary rotary packing ring, rotation are equipped between shell and motor input shaft Formula rotary packing ring can make the intracorporal lubricating oil of shell flow to connector.
Preferably, the connector is connection spline.
Preferably, the rotary rotary packing ring is oil sealing.
Preferably, the transmission input shaft is equipped with external splines, and the motor input shaft is equipped with internal spline, the gearbox Input shaft and the motor input shaft are cooperated together by the external splines and the internal spline.
The lubrication system of bridge case integrated gearbox system described in the utility model has the beneficial effect that
1, by the way that connector is arranged between transmission input shaft and motor input shaft, gearbox, motor and drive are realized Dynamic bridge, which is the integrated design, saves installation space, reduces manufacturing cost.
2, by installing rotary rotary packing ring between transmission input shaft and motor input shaft, connector is enhanced Lubrication and cooling effect, improve the service life of connector.
3, transmission input shaft is cooperated using spline and motor input shaft, and oil sealing is loaded on motor input shaft, such oil liquid It is able to enter spline, can easily play lubricating action.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the lubrication system of the bridge case integrated gearbox system.
Description of symbols: 1- shell;2- transmission input shaft bearing;3- transmission input shaft;4- motor input shaft axis It holds;The rotary rotary packing ring of 5-;6- motor input shaft;7- connector.
Specific embodiment
With reference to the accompanying drawings and detailed description, to the lubrication knot of bridge case integrated gearbox system described in the utility model Structure is further described.
It should be noted that the "left", "right" in the utility model is not intended to limit only for the purposes of the positional relationship of description component Determine position of the component in real space.
As shown in Figure 1, the lubrication system of the bridge case integrated gearbox system, including shell 1 and along axial direction from a left side to The right side is sequentially arranged at transmission input shaft 3 and motor input shaft 6 in shell 1, and transmission input shaft 3 passes through transmission input shaft Bearing 2 is installed within the case 1, and motor input shaft 6 is installed within the case 1 by motor bearing of input shaft 4, transmission input shaft 3 It is connected with motor input shaft 6 by connector 7;Rotary rotary packing ring 5 is equipped between shell 1 and motor input shaft 6,
Preferably, connector 7 is connection spline.
Preferably, rotary rotary packing ring 5 is oil sealing.
Preferably, transmission input shaft 3 is equipped with external splines, and motor input shaft 6 is equipped with internal spline, 3 He of transmission input shaft Motor input shaft 6 is cooperated together by external splines and internal spline.
The working principle of the lubrication system of bridge case integrated gearbox system described in the utility model is: shell 1 and motor are defeated Enter and be equipped with rotary rotary packing ring 5 between axis 6, in 6 rotary course of motor input shaft, rotary rotary packing ring 5 can stop Lubricating oil flows to except shell 1, so that lubricating oil is back to connector 7, to lubricate connector 7.
