Description

A kind of concentric assembled shaft being connected of motor in electric automobile axle and gearbox that guarantees
Technical field
The utility model relates to electric-vehicle part assembly tool field, is specifically related to a kind of concentric assembled shaft being connected of motor in electric automobile axle and gearbox that guarantees, is while being linked and packed for electric automobile motor axle and gearbox, guarantees the machine equipment of its concentricity.
Background technology
Repacking pure electric automobile, the output shaft of motor and the connection of gearbox complete by clutch.The power of motor is that the shaft coupling by being arranged on motor shaft is passed to flywheel.When running car, the pressing plate in clutch, by the active force of one group of spring, is pressed in friction plate on flywheel end face tightly; The flywheel of rotation is just sent to gearbox and walking mechanism by friction plate and the splined shaft that is inserted in friction plate center by power, drives vehicle wheel rotation.When driver's let slip the clutch, while needing shifted position or stagnation of movement, pedal travel makes mechanical linkage compression rag iron spring, makes to move after pressing plate, and friction plate departs from flywheel, and motor outputting power is cut off.Release the clutch pedal, friction plate is pressed in again on flywheel, and vehicle continues to travel.
In practical set, first flywheel and clutch part need to be dressed up to an integral body, and then and gearbox power shaft docking (insertion).Gear-box axle enters the external splines of axle head and the internal spline at friction plate center is the sliding matching structure of machining, can not be concentric or Concentricity tolerance is excessive if be pressed on friction plate internal spline on flywheel and gearbox axle head external splines, all cannot dock.When especially the pure electric automobile of separate unit repacking assembles, need repeated multiple times adjustment friction plate position, gearbox could be packed into.
If it is convenient for assembly to want to process a technique splined shaft, the one, auto parts and components drawing is difficult to find, if adopt mapping processing, the dimensional tolerance that resembles the interior external splines that is slidably matched is difficult to meticulous mapping, even if preliminary survey completes, the man-hour of single-piece work, reparation match grinding is also very long, and processing charges is very high, so this process procedure is more difficult in pure electric automobile restructuring process.
Utility model content
The purpose of this utility model is to provide a kind of concentric assembled shaft being connected of motor in electric automobile axle and gearbox that guarantees, it is the machine equipment that guarantees its concentricity while being linked and packed for electric automobile motor axle and gearbox, can guarantee to connect concentricity requirement, can cut down finished cost again, save installation work-hour.
For achieving the above object, the utility model has adopted such technical scheme: described assurance motor in electric automobile axle and the concentric assembled shaft being connected of gearbox, by technique splined shaft, screw rod, formed, it is characterized in that, wherein one end of technique splined shaft is splined end, the other end is concentric locating styletable, and splined end is a concentric body with concentric locating styletable; The external diameter of splined end is greater than the external diameter of concentric locating styletable; The center of splined end is prefabricated with screw hole, and in screw hole, coupling has screw rod.
Motor coupling and flywheel are connected and fixed as concentric structure, and the shaft hole diameter of motor coupling is identical with the external diameter of concentric locating styletable, and guarantee that concentric locating styletable slidably inserts among the shaft hole diameter of motor coupling; The spline inner diameter of friction plate is identical with the external diameter of splined end, and guarantees that splined end slidably inserts among the spline inner diameter of friction plate, and the axis hole outer end of motor coupling is connected with motor in electric automobile axle.
The making of technique splined shaft, can be processed into the specification that meets designing requirement according to matching requirements; Also can look for a waste and old gearbox of same specification, pull down its power shaft and make.Because the splined end of technique splined shaft is a concentric body with concentric locating styletable, motor coupling and flywheel are connected and fixed as after concentric structure, then with concentric locating styletable Matching installation; Splined end slip is inserted friction plate and is formed concentric body with concentric locating styletable equally; By circumference diagonal order, tighten one by one the housing bolt of clutch, make friction plate by tightly, concentric being pressed on flywheel end face (do not draw clutch housing bolt) in figure.Can guarantee that like this friction plate and motor coupling, flywheel are connected and fixed as concentric structure.Now, utilize screw rod that technique splined shaft is transferred to, still can guarantee that friction plate is connected concentric structure with motor coupling, flywheel, then the power shaft of the gearbox on electric automobile is assemblied in the splined hole of friction plate, the axis hole outer end of motor coupling is connected with motor in electric automobile axle; The power shaft that can guarantee like this motor in electric automobile axle, motor coupling, flywheel, friction plate, gearbox is concentric structure.
Accompanying drawing explanation
It shown in accompanying drawing, is the schematic diagram of the utility model concrete structure and using method.
The specific embodiment
As shown in the figure, described a kind of concentric assembled shaft being connected of motor in electric automobile axle and gearbox that guarantees, by technique splined shaft, screw rod 2, formed, it is characterized in that, wherein one end of technique splined shaft is splined end 1, the other end is concentric locating styletable 6, and splined end 1 is a concentric body with concentric locating styletable 6; The external diameter of splined end 1 is greater than the external diameter of concentric locating styletable 6; The center of splined end 1 is prefabricated with screw hole 5, and the interior coupling of screw hole 5 has screw rod 2.
Motor coupling 3 is connected and fixed as concentric structure with flywheel 7, and the shaft hole diameter of motor coupling 3 is identical with the external diameter of concentric locating styletable 6, and guarantees that concentric locating styletable 6 slidably inserts among the shaft hole diameter of motor coupling 3; The spline inner diameter of friction plate 4 is identical with the external diameter of splined end 1, and guarantees that splined end 1 slidably inserts among the spline inner diameter of friction plate 4, and the axis hole outer end of motor coupling 3 is connected with motor in electric automobile axle 8.
Adopt after said structure, the power shaft connection that can guarantee motor in electric automobile axle 8, motor coupling 3, flywheel 7, friction plate 4, gearbox is concentric structure afterwards.
