The supporting overriding clutch assembly of described hybrid vehicle, initiatively the both sides diameter of ring A outer edge surface is less than initiatively ring A mid diameter, the both sides diameter of driven torus A endoporus is greater than the diameter in the middle part of driven torus A, between the little outer diameter face and the imperial palace diametric plane of rotating ring A both sides of active ring A, be separately installed with backup bearing A and backup bearing B.
The supporting overriding clutch assembly of described hybrid vehicle, described backup bearing A and backup bearing B is coaxially arranged.
The supporting overriding clutch assembly of described hybrid vehicle, the endoporus of active ring A is provided with invoice serration and is connected with engine crankshaft key.
Owing to have employed technique scheme, the present invention has following preceence:
1, the present invention is by controlling the engagement of overriding clutch assembly or surmounting connection or the disconnection that attitude changes driving engine and ISG motor in hybrid vehicle, achieves the object of double dynamical conversion; When engine drive, be engagement attitude by adjustment free-wheel clutch 4, power is passed to ISG motor terminal pad 7 by engine crankshaft 1, and realizing driven by engine motor drives jointly; When motor drives, by adjustment free-wheel clutch 4 for surmounting attitude, make motor power cannot back transfer to driving engine, achieve ISG motor and drive separately;
2,3 installation backup bearings between active ring 2 and driven torus, not only can make overriding clutch assembly bear axial load, and ensure that the coaxial precision of overriding clutch assembly, improve the high speed of overriding clutch assembly.

[detailed description of the invention]
Can explain the present invention in more detail by the following examples, the present invention is not limited to the following examples;
The supporting overriding clutch assembly of hybrid vehicle by reference to the accompanying drawings described in 1, comprise initiatively ring A2, driven torus A3, free-wheel clutch 4, backup bearing A5 and backup bearing B6, driven torus A3 is provided with in the outside of active ring A2, described free-wheel clutch 4 is arranged on the middle part initiatively between ring A2 and rotating ring A3, between active ring A2 and driven torus A3, the both sides of free-wheel clutch 4 are respectively equipped with backup bearing A5 and backup bearing B6, and one end end face of described driven torus A3 is fixedly connected with ISG motor terminal pad 7.
The supporting overriding clutch assembly of described hybrid vehicle, initiatively the both sides diameter of ring A2 outer edge surface is less than initiatively ring A2 mid diameter, the both sides diameter of driven torus A3 endoporus is greater than the diameter in the middle part of driven torus A3, between the little outer diameter face and the imperial palace diametric plane of rotating ring A3 both sides of active ring A2, be separately installed with backup bearing A5 and backup bearing B6.
The supporting overriding clutch assembly of described hybrid vehicle, described backup bearing A5 and backup bearing B6 is coaxially arranged.
The supporting overriding clutch assembly of described hybrid vehicle, the endoporus of active ring A2 is provided with invoice serration and is connected with engine crankshaft 1 key.
Implement the supporting overriding clutch assembly of hybrid vehicle of the present invention, by installing above-mentioned overriding clutch assembly, can realize driven by engine motor drive and pure motor drive two kinds of power conversion, its specific works principle is as follows:
1. driving engine translator drives:
Under this type of drive, engine crankshaft 1 drives initiatively ring A2 jointly to rotate, now active ring A2 rotating speed is higher than driven torus A3, free-wheel clutch 4 is driven to be adjusted to engagement attitude, to initiatively lock by ring A2 and driven torus A3, power is passed to driven torus A3 by active ring A2, and then reaches ISG motor by ISG motor terminal pad 7.
2. pure motor drives:
Under this type of drive, engine stop works, motor drives separately, now active ring A2 rotating speed is lower than driven torus A3, free-wheel clutch 4 is adjusted to and surmounts attitude, initiatively ring A2 and driven torus A3 is thrown off mutually, and now power oppositely cannot be passed to engine crankshaft 1 by ISG motor terminal pad 7, and namely driving engine is connected with ISG motor and disconnects.
Attachedly Figure 2 shows that the present invention one specific embodiment, the nominal torque of this cover overriding clutch assembly is 650N.m, and the rotating speed that surmounts allowable is 6000rpm.
Described overriding clutch assembly is made up of active ring B8, driven torus B9, diagonal-bracing type overriding clutch B10, deep groove ball bearing A11, deep groove ball bearing B12, circlip for bore A13 and circlip for bore B14; Wherein initiatively ring B8 endoporus is processed with invoice serration and is connected with engine crankshaft, outside face is processed into the stepped cylindrical structure that both sides diameter is less than mid diameter, and respectively as fitting surface in raceway in diagonal-bracing type overriding clutch B10 and deep groove ball bearing A15 and deep groove ball bearing B16; Driven torus B9 outer face is provided with flange and is connected with ISG motor terminal pad, the endoporus of driven torus B9 is processed as the stepped cylindrical structure that both sides diameter is greater than mid diameter equally, and respectively as the outer raceway of diagonal-bracing type overriding clutch B10 and exterior of deep groove ball bearing A11 and deep groove ball bearing B12, and be processed with groove in the both sides of driven torus B9 endoporus for installing circlip A13 and circlip for bore B14.
When engine drive, engine crankshaft drives the initiatively synchronized rotation of ring B8 by spline, now the rotating speed of active ring B8 is higher than driven torus B9, both velocity contrasts drive diagonal-bracing type overriding clutch B10 to be automatically adjusted to engagement, drives driven torus B9 and the synchronized rotation of active ring B8 by diagonal-bracing type overriding clutch B10 and the friction moment initiatively between ring B8, driven torus B9, so by Flange joint by transmission of power to ISG motor; When motor drives separately, driven torus B9 synchronous rotary is driven by Flange joint, now the rotating speed of driven torus B9 is higher than active ring B8, both velocity contrast drive diagonal-bracing type overriding clutch B10 are automatically adjusted to and surmount state, now initiatively ring B8 and driven torus B9 disconnects, and achieves motor and drives separately.
Part not in the detailed description of the invention is prior art.
The embodiment selected in this article in order to open goal of the invention of the present invention, currently thinks to be suitable for, but it is to be understood that the present invention is intended to comprise all changes belonging to the embodiment in this design and invention scope and improvement.
