For being not provided with the power assembly 1000 of locking system 200, structure such as Fig. 7 of housing 103 and speed changer 102- Shown in Figure 10, wherein as shown in figure 9, two third mounting hole R3 connections, the internal face W1 of third mounting hole R3 do not need to machine Working process.As shown in Figure 10, the other end of the second jackshaft III corresponding with third mounting hole R3 is supported on by bearing B1 In third mounting hole R3, the end face of the other end of the second jackshaft III is substantially concordant with the end face of bearing.

In the specific embodiment of the power drive system 10000 of the present invention, the first of same power assembly 1000 Locking system 200,200 same power assembly 1000 of locking system are set between Power Component 100a and the second Power Component 100b The first Power Component 100a and the second Power Component 100b be connected by locking system 200 it is synchronous with alternative, i.e., first Power Component 100a and during the second Power Component 100b lockings, can be such that the wheel that the first Power Component 100a drives is moved with second The wheel of power component 100b drivings rotates synchronously.

In this embodiment, the first Power Component 100a and the second Power Component 100b can work independently, and be independent of each other, First Power Component 100a and the second Power Component 100b can also work asynchronously, and make the gear synchronous rotation of the left and right sides, with Just it when single wheel skids wherein, gets rid of poverty.

For setting structure such as Fig. 7-figure of the power assembly 1000 of locking system 200, housing 103 and speed changer 102 Shown in 10, wherein as shown in figure 13, and middle casing 104 limits accommodating chamber 1041, locking system 200 is arranged on the accommodating chamber In 1041, two third mounting hole R3 connections, and the accommodating chamber 1041 is limited jointly, the internal face W1 of third mounting hole R3 Need mechanical process.As shown in figure 14, the other end of the second jackshaft III corresponding with third mounting hole R3 passes through bearing B1 It is supported in third mounting hole R3, the other end of the second jackshaft III passes through bearing B1 and exceeds bearing B1, and the part exceeded Equipped with locking system connecting portion C, locking system connecting portion C is used to be connected with locking system 200.In a specific embodiment In, locking system connecting portion C is used to by spline structure be connected with locking system 200.

Some embodiments of power drive system 10000 according to the present invention are briefly described below, in these embodiments, Power drive system 10000 includes locking system 200 and at least one power assembly 1000.

Power assembly 1000 include the first Power Component 100a and the second Power Component 100b, the first Power Component 100a with Second Power Component 100b is symmetrical arranged in the lateral direction, the first Power Component 100a for drive left side wheel, second For Power Component 100b for driving the wheel on right side, the first Power Component 100a and the second Power Component 100b include housing 103 are adapted to be attached to the vehicle of motor 101 and respective side with the motor 101 and speed changer 102, speed changer 102 being located in housing 103 Between wheel.

As shown in Figure 12-Figure 15, the coupling part of two connected settings of housings 103 and two housings 103 limits receiving Chamber 1041, locking system 200 are located in accommodating chamber 1041, wherein the first Power Component 100a and the second Power Component 100b pass through Locking system 200 is connected synchronous with alternative.

Thus the tool of power assembly 1000 is there are two types of working condition, i.e. unlocked state and lockup state, at power assembly 1000 When lockup state, the first Power Component 100a is synchronous by locking system 200 with the second Power Component 100b, so as to make first The wheel of Power Component 100a drivings and the wheel of the second Power Component 100b drivings rotate synchronously；Power assembly 1000 is in solution During lock status, the first Power Component 100a and the second Power Component 100b are mutual indepedent.

When single wheel skids, locking system 200 synchronizes the first Power Component 100a and the second Power Component 100b, from And export the power of the corresponding Power Component for the wheel not skidded to the wheel of skidding side by locking system 200, it realizes Power drive contributes to vehicle to get rid of poverty.

When the Power Component damage of side or failure, it is dynamic that locking system 200 synchronizes the first Power Component 100a and second Power component 100b, so as to be exported the power of the Power Component of normal work to the power packages of opposite side by locking system 200 For part to drive the wheel of the side, realization power drive is more convenient to use.

Power drive system 10000 according to embodiments of the present invention by setting locking system 200, can play power The maximum power transmission advantage of transmission system 10000, the enhancing of vehicle dynamic property help to get rid of poverty, and side wherein when skidding Power Component damage when, remain to normal driving vehicle.

The tool of power drive system 10000 is there are two power assembly 1000, and two power assemblies 1000 respectively drive vehicle Front-wheel and vehicle trailing wheel.

In some embodiments, locking system 200 can be one, the of one in two such power assembly 1000 One Power Component 100a and the second Power Component 100b is connected synchronous with alternative by locking system 200.In this way, preceding driving In power assembly 1000 and rear-guard power assembly 1000, there is provided the power assemblies 1000 of locking system 200, and power performance is good, take off Tired ability is strong.

In further embodiments, locking system 200 can be two, the first Power Component of each power assembly 1000 100a and the second Power Component 100b is connected synchronous with alternative by a locking system 200.Driving force is total before in this way Good into 1000 and 1000 equal power performance of rear-guard power assembly, ability of getting rid of poverty is strong.

In this embodiment, locking system 200 is arranged between two speed changers 102, so as to which two speed changers 102 pass through Locking system 200 is connected synchronous with alternative.

In embodiment of the speed changer 102 for triple reduction gear, two the second jackshafts III are connected by locking system 200 Synchronous with alternative, between locking system 200 is arranged in two the second jackshafts III, locking system 200 needs synchronous The rotating speed of two axis is moderate, and locking system 200 and the gear of triple reduction gear are not interfered, and are occupied little space simultaneously, power is total Layout into 1000 inside can be more reasonable.

As shown in Figure 13 and Figure 15, the second sub- 102 housing 103 of speed changer of the first Power Component 100a and the second power packages The second sub- 102 housing 103 of speed changer of part 100b is connected and limits accommodating chamber 1041 jointly, and locking system 200 is arranged on appearance It receives in chamber 1041, more specifically, two the second sub- 102 housings 103 of speed changer are integrally formed middle casing 104, middle casing It is set on 104 there are two III one-to-one two third mounting holes R3 of the second jackshaft with triple reduction gear, two thirds are pacified Dress hole R3 is interconnected and limits accommodating chamber 1041 jointly.

Locking system 200 according to the present invention is described referring to Figure 16-Figure 19.Locking dress as shown in Figure 16-Figure 19 200 are put as unidirectional locking arrangement 200a.As shown in Figure 16-Figure 19, locking system 200 includes first flange 201a, second flange 201b, synchronous ring 202 and drive component 203.
