Embodiment

Below in conjunction with accompanying drawing, multiplex speed changer provided by the present invention is elaborated.

As shown in Figure 1, speed changer of the present invention comprises input shaft 10,11, for convenience, describes jack shaft 20 and output shaft 30, the setting parallel to each other of above-mentioned rotatingshaft in this specification with the first input shaft 10, the second input shafts 11.Between each rotatingshaft, by driving gear, interconnect.Wherein driving gear 101-103 is arranged at input shaft 10 rotationally, on 11 (be that gear 101-103 can rotate jointly with input shaft 10,11, can be not and input shaft 10 yet, 11 rotations jointly), with the first input gear 101, the second input gear 102, the 3rd input gear 103, represent; Driving gear 201 and 202 is fixedly installed on jack shaft 20 and (can jointly rotates with jack shaft 20), driving gear 203-205 is arranged on jack shaft 20 rotationally, with upper transfer gear, represents respectively with the first intermediate gear 201, the second intermediate gear 202, the 3rd intermediate gear 203, the 4th intermediate gear 204, the 5th intermediate gear 205; Driving gear 301,302 is fixedly installed on output shaft 30, with the first output gear 301, the second output gear 302, represents.

Wherein, the first input gear 101, the second input gear 102, the 3rd input gear 103 are meshed with the first intermediate gear 201, the second intermediate gear 202, the 3rd intermediate gear 203 respectively; The 4th intermediate gear 204, the 5th intermediate gear 205 are meshed with the first output gear 301, the second output gear 302 respectively.

More reasonable for speed changer inner space is arranged, input shaft 10,11 and output shaft 30 is coaxially arranged, i.e. the first input shaft 10 and the second input shaft 11 arranged concentric, the second input shaft 11 is hollow sleeve tubular axis, is placed on outside the first input shaft 10, can separately rotate with the first input shaft 10; Output shaft 30 and input shaft 10,11 threes are on same rotation centerline.So just, form the rotation centerline of input shaft 10,11 and output shaft 30 and the rotation centerline of jack shaft 20 is parallel to each other.

Be provided with four synchronizer assembly C1, C2, C3, C4, can optionally make power transmit between driving gear, to realize different velocity ratios.Synchronizer assembly can adopt the synchronous coupling arrangement of manual transmission etc. in prior art, or engaging clutch or friction clutch etc.Particularly, be arranged on the second input shaft 11, can be optionally the first input gear 101 or the second input gear 102 be connected in to the first synchronizer C1 of the second input shaft 11; Be arranged on the first input shaft 10, can be optionally the second input gear 102 or the 3rd input gear 103 be connected in to the second synchronizer C2 of the first input shaft; Be arranged on jack shaft 20 the 3rd switching mechanism C3 that the 3rd intermediate gear 203 can be connected with jack shaft 20; Be arranged on jack shaft 20 the 4th synchronizer C4 that can optionally the 4th intermediate gear 204 is connected or be separated with jack shaft 20 with the 5th intermediate gear 205.

Similar with the COMM communication in prior art speed changer, when using synchromesh gear, in switching mechanism (C1-C4), sleeve spline is engaged to and rotatingshaft (10,11,20,30) hub of one, and each driven gear is provided with chamfering or the spline being integrally formed therewith, when sleeve moves along axial direction, sleeve little by little spline fitted to described chamfering or spline.In addition, such circle is set: it little by little rubs with the predetermined member of being located in driven gear side, with the motion along with sleeve, makes rotary synchronous.It can be also that electronic mechanism is controlled that the sleeve of each mechanism can be controlled by machinery.

Therefore, the first switching mechanism C1 of take is example, and when the sleeve of C1 is moved to the left, when the one hub that is arranged at the first input shaft 10 and the second input shaft 11 is linked together, the first input shaft 10 is realized and being connected with the second input shaft 11; When the sleeve of C1 moves right, when being arranged at the first input shaft 10 and the 3rd input gear 103 and extending the one hub arranging and link together, the first input shaft 10 is realized and being connected with the 3rd input gear 103; When the sleeve of C1 is placed in neutral position, while not being connected with any one driving gear or rotatingshaft, switching mechanism C1 is in neutral.The working method of above-mentioned driving mechanism is equally applicable to other switching mechanism (C2, C3, C4).

Similarly, when switching mechanism adopts bi-directional friction clutch, its control mode can also adopt machinery to control also can adopt electronic mechanism control.
