The utility model discloses reduce unsprung mass and vibration, be favorable to providing whole car ride comfort and travelling comfort, make things convenient for the motor model preferred simultaneously, realize that two positive and negative direction transmission torque are unanimous, be favorable to feedback brake.
Description
Technical field：
The utility model is related to electric automobiles, relates generally to a kind of pure electric power transmission system frame in plate spring suspension brackets chassis
Structure.
Background technology：
Vehicle bridge on the market is divided into two kinds at present, a kind of propons for being not possess driving function, one kind be band main reducing gear,
Differential mechanism and two semiaxis have the back axle of driving function.Traditional vehicle bridge makees electric motor car, and power transmission shaft occupies side rail inner space, leads
Vehicle space is caused to be underutilized；Power transmission shaft itself has weight, and transmission system inertia is larger；Traditional vehicle bridge integrated master subtract
Fast device uses gear with curved teeth, and both forward and reverse directions transmission is inconsistent, causes regenerative braking drive line vibrations.In order to adapt to electric automobile, newly
Develop electric drive axle motor and decelerator being integrated on axle housing, the electric drive axle of the program causes unsprung mass larger,
Axle vibraqtions energy is larger, causes vehicle ride comfort, comfortableness and leaf spring fatiguability to damage.
Utility model content：
The utility model purpose is exactly to make up the defect of prior art, there is provided a kind of pure electric power in plate spring suspension brackets chassis
Transmission system framework, carries out motorized transformation, by the differential mechanism in traditional vehicle bridge to the conventional power system using plate spring suspension brackets
It is integrated into the association of motor and gearbox with decelerator, by the semiaxis driving moment with universal joint.
The utility model is achieved through the following technical solutions：
A kind of pure electric power transmission system framework in plate spring suspension brackets chassis, includes the vehicle bridge installed between the wheels, and it is special
Levy and be：Connected by leaf spring respectively between the two ends of the vehicle bridge and chassis member, motor and gearbox association are logical
Cross motor suspension bracket to be fixed between chassis member, vehicle bridge two ends wheel is by the semiaxis with universal joint and gearbox
Differential mechanism is connected, and the motor drives vehicle bridge both sides vehicle wheel rotation by gearbox and semiaxis.
The output torque of motor is passed through differential mechanism by the gearratio for having 2 or more in described gearbox association
Two ends wheel is transmitted with semiaxis, the output end that the motor is located in gearbox body is provided with for changing gearbox
Keep off the gearshift for manipulating.
Only have 1 gearratio that the output torque of motor is passed through into differential mechanism and semiaxis in described gearbox association
Transmission two ends wheel.
Its principle is：On the Special vehicle chassis using plate spring structure, realize motor and speed change with differential mechanism
Case is fixed to the pure electric drive system on chassis.When the gearratio for having 2 or more in gearbox association, gearbox can be with
It is 2 gears, 3 gears or 4 gear iso-variable velocity casees, the Gear shift operation mechanism of gearbox can be with manually operated, it would however also be possible to employ automatic control
Mechanism's operation processed.When the change-speed gearing logarithm for having 1 ratio gearbox in gearbox association can be a pair, two pairs, three
Equity, but finally only form a fixed gearratio.
The utility model has the advantages that：
(1) motor direct-drive, is realized on plate spring structure Special vehicle chassis, but motor and gearbox (band differential mechanism)
It is fixed on chassis, relatively conventional vehicle bridge reduces unsprung mass, reduces vibration under spring, is conducive to provide vehicle ride comfort
And comfortableness.
(2), the fast ratio of gearbox be able to can be changed with careful design that is, the course of work, to facilitate motor model preferably,
Maximum possible reduces size, weight and cost of motor etc..
(3), main reducing gear gear wheel does not select gear with curved teeth, can select helical gear etc., realizes positive and negative both direction driving torque
Unanimously, regenerative braking is conducive to.
Brief description of the drawings：
Fig. 1 is the structural representation that the utility model changes gearratio.
Fig. 2 is the structural representation of the utility model fixed drive ratio.
Specific embodiment：
A kind of pure electric power transmission system framework in plate spring suspension brackets chassis, is shown in Fig. 1, includes the car between wheel 1
Bridge 9, is connected by leaf spring 8 respectively between the two ends of vehicle bridge 9 and chassis member 7, and motor 5 and the association of gearbox 4 pass through
Motor suspension bracket 6 is fixed between chassis member 7, and the output end that motor 5 is located in gearbox body is provided with for becoming
Fast case 4 carries out the gearshift 10 of shift control, and the two ends wheel of vehicle bridge 9 is by the difference on the semiaxis 2 with universal joint 3 and gearbox
Fast device connection, the motor drives vehicle bridge both sides wheel 1 to rotate by gearbox and semiaxis, has 2 in described gearbox
The output torque of motor is transmitted two ends wheel 1 by individual or more gearratio by differential mechanism and semiaxis.
See Fig. 2, include the vehicle bridge 9 between wheel 1, be respectively mounted between the two ends of vehicle bridge 9 and chassis member 7
Have a leaf spring 8, motor 5 and gearbox 11 be integrated into an association by motor suspension bracket 6 be fixed on chassis member 7 it
Between, wheel 1 is connected to gearbox 11 by the semiaxis 2 with universal joint 3, and described only 1 gearratio of gearbox 11 will drive electricity
The output torque of machine transmits two ends wheel 1 by differential mechanism and semiaxis.
