The original round bush and the original reinforcing rib are integrated on the two end covers in the light split power transfer device, the external interface form of one end cover or two end covers in the transfer device can be changed according to different motor or gearbox types, any end cover can be separately changed and assembled and disassembled conveniently, and the welding-free structure is convenient for daily maintenance. Meanwhile, the transfer device has a few parts and only has machining parts of three parts, so the cost is reduced and the installation is simplified.
Description
Technical field
The present invention relates to the power switching device of elec. vehicle drive system, relate to a kind of split type power switching device of elec. vehicle drive system especially.
Prior art
Power switching device one end of common elec. vehicle is the end cap that connects motor, the other end is the end cap that connects change speed gear box, the centre is a round buss, this three is connected as a single entity by welding, and the part power switching device also need increase the weldering reinforced rib in the centre and have enough rigidity and intensity to guarantee structure.Two end caps all need and the round buss welding, and the end cap area is bigger usually, in order to satisfy the requirement of welding process, must keep enough spacings between two end cap, could allow welding process be finished smoothly.Must increase the length of whole power switching device like this, also increase the weight of power switching device, this all is unfavorable for the layout of power system on vehicle.
If can reduce the length of whole power switching device, alleviate the weight of power switching device, this development for elec. vehicle is highly profitable beyond doubt.Therefore be necessary to design the later-model power switching device of a cover, this device has little, the lightweight characteristics of volume, and does not need welding, is convenient to maintaining simultaneously again.
Summary of the invention
The invention provides a kind of light-duty split type power switching device.The end cap that wherein connects motor makes bolt together between the two with the end cap that is connected change speed gear box, the round buss in the middle of having saved, and avoided welding process, realized reducing the purpose of volume, expendable weight.Light-duty split type power switching device of the present invention is equivalent to that original round buss and reinforced rib are incorporated into two end caps and has got on, and can be according to an end cap in different motors or the gearbox-type replacing transition apparatus or the external interface form of two end caps, any end cap all can be changed separately, and easy to loading and unloading, unjointed structure also is convenient to daily maintenance.Simultaneously, this transition apparatus amount of parts is few, has only three part machined piece, is convenient to cost-cutting, simplifies and install.
Described power switching device is particularly useful for the drive system of elec. vehicle.
Power switching device of the present invention mainly is made of the end cap and the transmission shaft of the end cap that connects motor, connection change speed gear box, wherein connect the end cap of motor and connect between the end cap of change speed gear box with annulus location and bolt together, transmission shaft is connected with flywheel clutch with motor shaft respectively.The concrete structure of this device is described below:
1. the end cap (hereinafter to be referred as end cap A) that connects motor.Open circular hole in the middle of the end cap A, with the annulus coaxial positioning of motor output end.End cap A and motor chien shih bolt together, decide according to motor preformed hole position the position, hole.
2. the end cap (hereinafter to be referred as end cap B) that connects change speed gear box.End cap B and change speed gear box make bolt together, and decide according to the former connecting bore of change speed gear box position the position, hole.
Location between end cap A and the end cap B be connected.Use coaxial positioning annulus location between end cap A and the end cap B.Open the through hole of the band heavy stand of some on end cap A, correspondence position is opened hole and tapping on end cap B, makes bolt up end cap A and end cap B then, smears screw thread fastening glue during assembling.End cap A is equivalent to form between the at both ends lid round buss of a hollow with after end cap B is connected, and this round buss has enough thickness, can avoid additionally using reinforced rib.
4. the design of transmission shaft.Transmission shaft is arranged in the middle of the hollow round buss that forms between two end cap, and according to the length that motor shaft head stretches out, motor shaft head set collar of the correspondence position of through hole welding uses bolt that transmission shaft and motor shaft is fastening in transmission shaft.
5. the location of transmission shaft on power switching device.One end of transmission shaft is connected on the motor shaft, and the other end of transmission shaft is used for fixing the flywheel clutch assembly.Because motor shaft does not allow to bear the additional load that flywheel weight produces, therefore a fulcrum ball bearing is installed in the middle of end face B, this bearing is used for locating and supporting drive shaft.
The light-duty split type power switching device structure of annex that satisfies above function as shown in Figure 1.
The bolt that plays fastening effect mentioned above preferably uses interior hexagonal cylinder head bolt.
Description of drawings
Fig. 1 is the sectional drawing of power switching device of the present invention, 1 end cap that connects motor wherein, and 2 bolts, 3 connect the end cap of change speed gear boxs, 4 bearings, 5 motor shaft head set collars, 6 transmission shafts.
Fig. 2 is the block diagram of power switching device of the present invention.
The specific embodiment
As shown in Figure 1, power switching device of the present invention is made of the end cap 3 and the transmission shaft 6 of the end cap 1 that connects motor, connection change speed gear box.Wherein, circular hole is opened in the centre that connects the end cap 1 of motor, with the annulus coaxial positioning of motor output end, 1 with motor chien shih bolt together, decide according to motor preformed hole position the position, hole; The end cap 3 that connects change speed gear box makes bolt together with change speed gear box, and decide according to the former connecting bore of change speed gear box position the position, hole.
Use coaxial positioning annulus location between 1 and 3.Open the through hole of the band heavy stand of some on 1, correspondence position is opened hole and tapping on 3, and hexagonal cylinder head bolt 2 fastening 1 and 3 in using is then smeared screw thread fastening glue during assembling.1 with after 3 are connected, and are equivalent to form between the at both ends face round buss of a hollow, and this round buss has enough thickness, can avoid additionally using reinforced rib.
A fulcrum ball bearing 4 is installed in the middle of 3, and this bearing 4 is used for locating and supporting drive shaft 6, thereby makes motor shaft not be subjected to the additional load that flywheel weight produces.
