Wheel transmission connection.Here, the first gear gear set can be low-grade location gear set, and the second gear gear set can be high gear tooth
Wheel group.
First motor 11 is connected with engine 1.First motor 11 can not only be used for generator to be used to generate electricity, but also as electricity
Motivation is for driving vehicle.Second motor 12 is connected with main shaft 2, and the second motor 12 can not only be used for motor for driving vehicle
, but also as generator for generating electricity.In the embodiment shown in figure 1, the line shaft empty set of the second motor 12 is
On the line shaft of one motor 11, so that the structure of hybrid electric drive system is more compact, shorten axial length, convenient in vehicle
Upper arrangement.
Main shaft 2 and countershaft 3 are disposed in parallel relation to one another, and are mounted on the cabinet of the speed changer by bearing.
Output section 10 is configured to for the power that speed changer exports to be transferred to the wheel of vehicle, such as the output section 10 can
To include output gear 101 and differential mechanism.Output gear 101 is connect with countershaft 3, and is nibbled with the final gear of differential mechanism 102
It closes；In other implementations, the output section 10 also may include differential mechanism.

What axis 2 was fixedly connected, to be rotated with main shaft 2.More specifically, the first driving gear 4 can be integrally formed with main shaft 2, it can also
To be connected by key with main shaft 2.
The freewheel clutch is arranged between the first gear gear set and main shaft, or is arranged in the first gear gear set
Between countershaft, engagement by freewheel clutch with separate, so that the first gear gear set is engaged or is separated with main shaft power,
The first gear gear set is either set to engage or separate with countershaft power, so that the switching of power is realized, to realize speed changer
The switching of gear.The freewheel clutch is well known to those skilled in the art, no longer detailed to its structure and working principle at this
State, but due to the particularity of application scenarios, this hybrid power system is using the advantages of freewheel clutch: (1) surmount from
Clutch is that the engagement or separation of two rotating elements are realized using the rotational speed difference of inside and outside two rotating elements, does not need to utilize electricity
Machine or hydraulic module provide engagement or isolated power, and therefore, overrun clutch structure is simple, reliable and stable, can
The reliability of hybrid power system shift is effectively provided；(2) freewheel clutch can avoid keeping off for synchronizer
The momentary interruption of torque transmitting, guarantees the ride comfort of vehicle shift when the switching of position.
In the first embodiment shown in Fig. 1, the setting of freewheel clutch 8 the first driven gear 5 and countershaft 3 it
Between, the torque transmitting for being switched on or switched off between the first driven gear 5 and countershaft 3.In brief, shown in Fig. 1 first
In kind embodiment, when the revolving speed of the first driven gear 5 is greater than or equal to the revolving speed of countershaft 3, freewheel clutch 8 is engaged；When
When the revolving speed of first driven gear 5 is less than the revolving speed of countershaft 3, freewheel clutch 8 is separated.By in the first driven gear 5 and pair
Freewheel clutch 8 is set between axis 3, so that can only be passed along from main shaft 2 to the direction of countershaft 3 by the first gear gear set
Torque delivery, and torque cannot be transmitted along from countershaft 3 to the direction of main shaft 2 by the first gear gear set.
In the first embodiment shown in Fig. 1, first clutch 9 is connect with the second driving gear 6, for connect or
Disconnect the power transmitting between the second driving gear 6 and main shaft 2.When first clutch 9 engages, it keeps the second driving gear
6 initiatively connect to rotate with main shaft 2；When first clutch 9 separates, it, which disconnects the second driving gear 6 with main shaft 2, revolves
Turn.First clutch 9 can perhaps its engagement of wet clutch or discrete state can be by existing using existing dry type

Wheel 5, with the first driven gear 5 rotate synchronously) revolving speed be greater than freewheel clutch 8 interior rotating element (be fixed on countershaft 3, with
Countershaft 3 rotate synchronously) revolving speed, freewheel clutch 8 engage, 1 power of engine passed sequentially through from the first driven gear 5 surmount from
Clutch 8, countershaft 3 are transferred to output section 10, at this point, speed changer is in the first gear.It needs to switch to second gear from the first gear
When position, control first clutch 9 is engaged, and since the transmission ratio of the first gear is greater than the transmission ratio of the second gear, leads to countershaft 3
Revolving speed instantaneously increases, so that the revolving speed of the outer rotating element of freewheel clutch 8 is less than the revolving speed of interior rotating element, freewheel clutch
8 disconnect, and complete from the first gear to the switching of the second gear.When needing to switch to the first gear from the second gear, control first
Clutch 9 disconnect, 1 power cut of engine, 3 revolving speed of countershaft reduce, when the revolving speed of countershaft 3 be down to it is driven equal to or less than second
When the revolving speed of gear 5, that is, when the revolving speed of the interior rotating element of freewheel clutch 8 is less than or equal to the revolving speed of outer rotating element, surpass
More clutch 8 engages, and completes from the second gear to the switching of the first gear.
It by the engagement of control first clutch 9 or disconnects, the gear driving of engine two not only may be implemented, may be implemented simultaneously
The driving of second 12 liang of motor gear.In this way, can choose the biggish gear of transmission ratio (the first gear) when needing lower speed；
When needing higher speed, the lower gear of transmission ratio (the second gear) can choose, to utmostly utilize the second motor
High efficiency region, and broader vehicle speed range can be obtained, while being conducive to motor miniaturization, save system cost.

Gear 13 and the second speed increasing gear 14, the power axis connection of the first speed increasing gear 13 and first motor 11, the second speed increasing gear 14
Connect with main shaft 2, wherein the number of teeth of the first speed increasing gear 13 less than the second speed increasing gear 14 the number of teeth so that first motor 11
Revolving speed be greater than engine 1 revolving speed.
In other embodiments, the line shaft of first motor 11 can be connected with countershaft 3.By by first motor 11
Power is connected with countershaft 3, and 11 liang of gear power generations of first motor may be implemented.The working principle and engine of the gear power generation of first motor two
The working principle of two gear drivings is similar, and details are not described herein.
Second motor 12 can be connected by any suitable mode with countershaft 3, such as be connected by gear drive.
Specifically, in the embodiment shown in figure 1, gear drive includes that intermeshing first transmission gear 15 and second passes
Moving gear 16, the line shaft of the second motor 12 are connect with the first transmission gear 15, and the second transmission gear 16 is connect with countershaft 3.
Freewheel clutch 8 can be arranged in main shaft 2, can also be arranged in countershaft 3；First clutch 9 can be arranged in master
Axis 2 can also be arranged in countershaft 3.
It should be noted that in the case where freewheel clutch 8 is arranged in main shaft 2, when the revolving speed of main shaft 2 is greater than the first master
When the revolving speed of moving gear 4, freewheel clutch 8 is engaged；When revolving speed of the revolving speed of main shaft 2 less than the first driving gear 4, surmount from
Clutch 8 disconnects.And in the case where freewheel clutch 8 is arranged in countershaft 3, when the revolving speed of the first driven gear 5 is greater than countershaft 3
When revolving speed, freewheel clutch 8 is engaged；When the revolving speed of the first driven gear 5 is less than the revolving speed of countershaft 3, freewheel clutch 8 divides
From.
