Description
Technical field
A kind of automotive proplsion is the utility model is related to, particularly a kind of new rear driving axle assembly.
Background technology
Drive axle is to change rotating speed and torque from speed changer positioned at power train end, and passes them to driving
The mechanism of wheel；Drive axle is generally made of main reducing gear, differential mechanism, wheel drive and driving axle housing etc..Patent publication No.
CN205168186U discloses a kind of novel rear drive axle assembly, it realizes steering rotation by increasing by an assisted diversion differential mechanism
Complete to turn to the mode being combined with driving wheel assisted diversion, reduce the turning radius of automobile, improve Vehicular turn
When passability and flexible performance.But containing there is problems with actual application：
1. during vehicle running driving, meeting fuel consumption increases the discharge capacity of tail gas, and then pollutes environment；
2. driving axle housing and main reducing gear band differential assembly installation unbalance loading, influence the ride comfort of vehicle.
Utility model content
It is above-mentioned in order to solve the problems, such as, the utility model discloses a kind of new rear driving axle assembly, include bridge
Body, axle housing, electric controller, motor, brake, wheel hub, limited-slip differential, rotational speed governor, differential assembly and retarder
Assembly, the wheel hub are installed on the both sides of pontic, are provided with axle housing on the pontic, be assembled with the axle housing electric controller,
Motor, brake, differential assembly and speed reducer assembly, the medial surface of the wheel hub are provided with limited-slip differential and rotating speed control
Device processed.
Further, it is provided with dust cover on the outside of the limited-slip differential and rotational speed governor.
The utility model uses the supplement power that Electronic control is controlled as fuel engines, and control drives vehicle bridge, not only
Fuel consumption can be reduced, can also make Emergency use when for some reason oil plant can not be replenished in time in automobile, to drive automobile to travel in short-term,
Saving fuel oil, reduces exhaust emissions, environmental protection.Control device is also installed on the both sides of pontic by the utility model, ensure that
The ride comfort of vehicle.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
In figure：1st, pontic, 2, axle housing, 3, electric controller, 4, motor, 5, brake, 6, wheel hub, 7, limited-slip differential,
8th, rotational speed governor, 9, dust cover, 10, differential assembly, 11, speed reducer assembly.
Embodiment
Elaborate below in conjunction with the accompanying drawings to specific embodiment of the utility model.
As shown in Figure 1, a kind of new rear driving axle assembly, includes pontic 1, axle housing 2, electric controller 3, motor 4, system
Dynamic device 5, wheel hub 6, limited-slip differential 7, rotational speed governor 8, differential assembly 10 and speed reducer assembly 11, the wheel hub 6 are installed
Axle housing 2 is provided with the both sides of pontic 1, the pontic 1, electric controller 3, motor 4, braking are assembled with the axle housing 2
Device 5, differential assembly 10 and speed reducer assembly 11, the medial surface of the wheel hub 6 are provided with limited-slip differential 7 and rotational speed governor
8。
As a preferred embodiment, a dust cover 9 is provided with the outside of limited-slip differential 7 and rotational speed governor 8, to increase
Add the service life of limited-slip differential 7 and rotational speed governor 8.
Automobile is during driving, and motor torque is passed on speed reducer assembly 11 by universal driving device, retarder
Assembly 11 is connected with differential assembly 10 by conical gear, and differential assembly 10 controls the rotation of pontic 1, realizes that reduction of speed increases
Torque.
For automobile during driving, vehicle is in the state that powers on, can be by controlling electric controller 3 to control motor
4, and then start brake 5, the rotary speed of wheel hub 6 is controlled by brake 5.In addition electric controller 3 and motor 4
Setting can also make Emergency use when for some reason oil plant can not be replenished in time in automobile, to drive automobile to travel in short-term, saving fuel oil,
Reduce exhaust emissions, environmental protection.
Rotational speed governor 8 can change the gear structure of limited-slip differential 7 adjustment effect of limited-slip differential 7
It is dynamic, for example the single planetary gear in open differential is changed into dual planetary gear, and in 7 or so axle shaft gear of limited-slip differential
A pair of symmetrical gear (i.e. sun gear) of both sides arrangement, and sun gear is meshed with the big end gear of dual planetary gear respectively.And
And rotational speed governor 8 can be arranged at the axle journal of both sides sun gear and a pair of of rotational speed governor 8 is set, by controlling rotating speed
Device 8 is operated to limit the rotating speed of sun gear, and then controls the planetary gear being engaged with and the motion conditions of other gears, shape
Into the size and Orientation of active control or so axle shaft gear rotating speed difference.
