Abstract
The open a kind of plate spring suspension brackets chassis of the present invention pure electric power drive system framework, include the vehicle bridge installed between the wheels, it is characterized in that: be connected by leaf spring respectively between the two ends of described vehicle bridge and chassis member, described driving motor and change speed gear box association are fixed between chassis member by motor suspension bracket, described vehicle bridge two ends wheel is connected with the differential mechanism on change speed gear box by the semiaxis of band universal joint, and described driving motor drives vehicle bridge both sides vehicle wheel rotation by change speed gear box and semiaxis.Present invention decreases unsprung mass and vibration, be conducive to provide car load ride comfort and comfortableness；Facilitate motor model preferred, it is achieved positive and negative both direction driving torque is consistent, beneficially regenerative braking simultaneously.
Description
Technical field:
The present invention relates to electric automobiles, relate generally to a kind of plate spring suspension brackets chassis pure electric power drive system framework.
Background technology:
Vehicle bridge the most on the market is divided into two kinds, and a kind of is the propons not possessing and driving function, and one is band main reducing gear, differential
Device and two semiaxis have the back axle driving function.Tradition vehicle bridge makees electric motor car, and power transmission shaft occupies side rail inner space, causes whole
Car space is underutilized；Power transmission shaft self has weight, and drive system inertia is bigger；The main reducing gear that tradition vehicle bridge is integrated
Using gear with curved teeth, both forward and reverse directions transmission is inconsistent, causes regenerative braking drive line vibrations.In order to adapt to electric automobile, newly developed
Electric drive axle motor and decelerator being integrated on axle housing, the electric drive axle of the program causes unsprung mass relatively big, vehicle bridge
Vibrational energy is relatively big, causes car load ride comfort, comfortableness and leaf spring fatiguability to damage.
Summary of the invention:
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of plate spring suspension brackets chassis pure electric power drive system
Framework, carries out motorized transformation to the conventional power system using plate spring suspension brackets, by the differential mechanism in tradition vehicle bridge and decelerator
It is integrated in the association driving motor and change speed gear box, drives wheel by the semiaxis of band universal joint.
The present invention is achieved by the following technical solutions:
A kind of plate spring suspension brackets chassis pure electric power drive system framework, includes the vehicle bridge installed between the wheels, and its feature exists
In: being connected by leaf spring respectively between the two ends of described vehicle bridge and chassis member, described driving motor and change speed gear box association lead to
Crossing motor suspension bracket to be fixed between chassis member, described vehicle bridge two ends wheel is by the semiaxis of band universal joint and change speed gear box
Differential mechanism connects, and described driving motor drives vehicle bridge both sides vehicle wheel rotation by change speed gear box and semiaxis.
Described change speed gear box association there are 2 or above gear ratio the output torque driving motor is passed through differential mechanism
With semiaxis transmission two ends wheel, the outfan that described driving motor is positioned at gearbox body is provided with for changing change speed gear box
The gearshift that gear is handled.
In described change speed gear box association, only 1 gear ratio will drive the output torque of motor by differential mechanism and semiaxis
Transmission two ends wheel.
Its principle is: on the Special vehicle chassis using plate spring structure, it is achieved will drive motor and the speed change of band differential mechanism
Case is fixed to the pure electric drive system on chassis.When having 2 or above gear ratio in change speed gear box association, change speed gear box is permissible
Being 2 gears, 3 gears or 4 gear iso-variable velocity casees, the Gear shift operation mechanism of change speed gear box can artificially manual operation, it would however also be possible to employ automatically control
Mechanism processed operates.When the change-speed gearing logarithm having 1 ratio gearbox in change speed gear box association can be a pair, two to, three
Equity, but finally only form a fixing gear ratio.
The invention have the advantage that
(1), on plate spring structure Special vehicle chassis, realize motor direct-drive, but motor and change speed gear box (band differential mechanism) are fixed
On chassis, relatively conventional vehicle bridge, reduce unsprung mass, reduce and vibrate under spring, be conducive to provide car load ride comfort and relax
Adaptive.
(2), the speed ratio of change speed gear box can be able to change with careful design that is work process, to facilitate motor model preferred,
Maximum possible reduces the size of motor, weight and cost etc..
(3), main reducing gear gear wheel do not select gear with curved teeth, helical gear etc. can be selected, it is achieved positive and negative both direction driving torque
Unanimously, beneficially regenerative braking.
Accompanying drawing illustrates:
Fig. 1 is the structural representation that the present invention changes gear ratio.
Fig. 2 is the structural representation of fixed drive ratio of the present invention.
Detailed description of the invention:
A kind of plate spring suspension brackets chassis pure electric power drive system framework, is shown in Fig. 1, includes the vehicle bridge 9 being arranged between wheel 1,
It is connected by leaf spring 8 respectively between the two ends of vehicle bridge 9 with chassis member 7, drives motor 5 and change speed gear box 4 association to pass through motor
Suspension bracket 6 is fixed between chassis member 7, and the outfan driving motor 5 to be positioned at gearbox body is provided with for change speed gear box 4
Carrying out the gearshift 10 of shift control, vehicle bridge 9 two ends wheel is by the semiaxis 2 of band universal joint 3 and the differential mechanism on change speed gear box
Connecting, described driving motor drives vehicle bridge both sides wheel 1 to rotate by change speed gear box and semiaxis, described change speed gear box has 2 or
Above gear ratio will drive the output torque of motor by differential mechanism and semiaxis transmission two ends wheel 1.
See Fig. 2, include the vehicle bridge 9 being arranged between wheel 1, be respectively mounted between two ends and the chassis member 7 of vehicle bridge 9
Have a leaf spring 8, drive motor 5 and change speed gear box 11 be integrated into an association by motor suspension bracket 6 be fixed on chassis member 7 it
Between, wheel 1 is connected to change speed gear box 11 by the semiaxis 2 of band universal joint 3, and only 1 gear ratio of described change speed gear box 11 will drive electricity
The output torque of machine is by differential mechanism and semiaxis transmission two ends wheel 1.
