Drawings
Some specific embodiments of the present invention will be described in detail hereinafter, by way of illustration and not by way of limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale. In the drawings:
fig. 1 is a schematic structural diagram of a range extender assembly according to an embodiment of the present invention;
fig. 2 is a schematic cross-sectional view of an inner rotor generator of the range extender assembly shown in fig. 1.
Detailed Description
Fig. 1 is according to the utility model discloses an increase journey ware assembly's schematic structure chart. Fig. 2 is a schematic cross-sectional view of the inner rotor generator 2 in the range extender assembly shown in fig. 1. The range extender assembly according to an embodiment of the present invention is described with reference to fig. 1 to 2. The range extender assembly comprises an inner rotor generator 2 and an engine 1, the inner rotor generator 2 is connected with the engine 1 through a dual-mass flywheel 3, the engine 1 is connected with a primary flywheel 31 of the dual-mass flywheel 3 through a high-strength bolt 41, and a secondary flywheel 32 of the dual-mass flywheel 3 is connected with the inner rotor generator 2 through a spline to transmit torque, so that the influence of torsional vibration and vibration of the engine 1 on the quality, the performance and the service life of the inner rotor generator is reduced to the greatest extent. The primary flywheel and the secondary flywheel are in drive connection via a damper spring 33, which will not be described in detail here, since the construction of a dual mass flywheel is well known to the person skilled in the art. In some cases, the model or other parameters of the engine 1 and the inner rotor generator 2 are changed, which may cause the rear end rotational inertia of the damping spring 33 of the dual mass flywheel 3 to be too small (i.e. the secondary flywheel has too small mass), and there is a risk that the engine 1 vibrates greatly and the bearing bush is easily damaged.
To solve the problem, with reference to fig. 1, the range extender assembly in the present embodiment further includes an adjusting device 4 in addition to the engine 1, the inner rotor generator 2, and the dual mass flywheel 3. The dual mass flywheel 3 includes a primary flywheel 31 and a secondary flywheel 32. The primary flywheel 31 is fixedly connected with the engine 1, and the secondary flywheel 32 is in transmission connection with the inner rotor generator 2. The adjusting device 4 is sleeved outside the rotating shaft 21 of the inner rotor generator 2 and is fixedly connected with the rotating shaft so as to rotate coaxially with the rotating shaft under the driving of the rotating shaft, thereby adjusting the rotational inertia at the rear end of the damping spring 33 of the dual-mass flywheel 3. By adding the adjusting device on the rotating shaft of the inner rotor generator, the mass of the secondary flywheel is increased equivalently, so that the rear end rotational inertia of the damping spring 33 is improved. Then, the rotational inertia of the generator rotor is adjusted by adjusting the rotational inertia of the adjusting device 4, so that the purpose of adjusting the rotational inertia of the rear end of the damping spring 33 of the dual-mass flywheel 3 is achieved. Increase adjusting device 4 in original journey ware assembly and in order effectively to shorten the cycle of product development, reduce the cost of product development simultaneously, can play important effect on future journey ware development platform that increases.
Referring to fig. 1 and 2, the adjustment device is provided on a section of the rotating shaft between the secondary flywheel and the rotor of the inner rotor generator. . The spindle 21 is provided with a positioning spigot 22 for mounting the adjustment device 4. The positioning spigot 22 serves to position the adjustment device such that a predetermined distance is maintained between the adjustment device 4 and the secondary flywheel 32. The specific value of the preset distance is not limited in detail, and is set according to specific parameters of the engine 1 and the generator, so that the vibration of the engine 1 is reduced, and the bearing bush is prevented from being easily pulled. In the present exemplary embodiment, the adjusting device 4 is a flange. The flange is fixed to the shaft 21 between the secondary flywheel 32 and the generator rotor by means of bolts 41. Because the structure of the flange plate is simple, the cost can be effectively reduced. Specifically, a flange is mounted on the positioning spigot 22 of the rotating shaft 21 through a bolt 41, and the flange is perpendicular to and coaxial with the rotating shaft 21. Dynamic balancing is required before the flange plate is mounted. The installation method solves the problems of installation fastening and dynamic balance, achieves the adjustment of the rotational inertia at the rear end of the damping spring 33 of the dual-mass flywheel 3 by adjusting the rotational inertia of the flange plate (the mass of the flange plate), thereby replacing the scheme of redevelopment of the dual-mass flywheel 3 caused by product change, shortening the period of product development, reducing the cost of product development and playing an important role on a future range extender development platform.
The utility model also provides a vehicle installs the increase journey ware assembly in the above-mentioned arbitrary embodiment in the vehicle. In the range extender assembly of the present embodiment, an adjusting device is added to the rotating shaft 21 of the inner rotor generator. The adjusting device is positioned by the positioning spigot 22 on the rotating shaft 21 and then is fastened to the rotating shaft 21 by the bolt 41. Meanwhile, the flange plate has enough safety distance with the secondary flywheel 32 of the dual-mass flywheel 3, and the scheme is feasible in process and has reliability and safety. The rotational inertia of the rotor is adjusted by adjusting the rotational inertia of the flange plate, so that the purpose of adjusting the rotational inertia of the rear end of the damping spring 33 of the dual-mass flywheel 3 is achieved.
By adopting the range extender assembly, the rotational inertia at the rear end of the damping spring 33 in the dual-mass flywheel 3 is adjusted by adding the flange plate at the shaft extension end of the motor rotating shaft 21, the dual-mass flywheel 3 is replaced by the adjustment in the mode, the development period can be effectively shortened, the rotational inertia at two ends of the damping spring 33 of the dual-mass flywheel 3 in the range extender assembly is matched with low cost, and the matching of an engine shaft system is met.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
