Business's title.
The pure electronic main deceleration case general assignment of single-stage of automobile is the power for transmitting motor, is allowed to be adapted to garage
The need for sailing.Driven gear is set（Main reducing gear）The landing slow-speed of revolution in automotive transmission, can increase torque.By the number of teeth
Few driving gear realizes deceleration with the driven gear more than the number of teeth, and during automobile normal running, the rotating speed of motor is generally higher,
Rotating speed is reduced by deceleration case, rotating speed declines, moment of torsion is necessarily increased, and also increases deceleration case primary transmission
The transmission load of mechanism.So, therefore a main reducing gear is set before the differential mechanism of power right driving wheel shunting to the left, can
So that the moment of torsion of the motor transmission before main reducing gear reduces, while the size and quality of motor are also reduced, and manipulation spirit
It is quick laborsaving；And the pure main deceleration case of electronic single-stage be motor input spindle nose be connected with driving gear, motor drive driving gear
Axle is rotated, it is necessary to reach the purpose of deceleration when slowing down by regulation motor output speed, and no middle gearbox is simple in construction, into
This is low.
In the embodiment of the present invention, left cover 1 and right cover 2 are formed using aluminum alloy material die casting, and light weight, resistance to pressure is good, left
Lid 1 and right cover 2 play the work of fixed drive motor, driving gear and driven gear using high intensity, light aluminum alloy die casting
With.Left cover 1 and right cover 2 use ADC12 aluminium alloys, and ADC12 aluminium alloys belong to Al-Si-Cu systems alloy, ADC12 castability,
Resistance to pressure is good, suitable for manufacture die casting.Its mechanical property and machinability are good, and ADC12 contains Si9.6%~12.0%, and composition is in eutectic
Point or so, the mobility of alloy preferably, is suitable for die casting intricate casting, and its intensity is high, and resistance to pressure is good, and red brittleness is small.
The effect of differential assembly be to both sides semiaxis transmit power while, it is allowed to both sides semiaxis is with different rotating speeds
Rotation, is met two sidecar wheels and is made Unequal distance traveling in the form of pure rolling as far as possible, reduce the friction on tire and ground.Automobile exists
The path of wheel is circular arc during turn, if automobile is turned to the left, and the central point of circular arc is in left side, in the identical time, right
The camber line that side wheel is walked is longer than left-hand wheel, in order to balance this difference it is necessary to left side wheel slow, the right wheel fast one
Point, the difference of distance is made up with different rotating speeds.If front and rear wheel shaft is integrally formed, it can not just accomplish both sides wheel
Speed difference, that is, do not accomplish adjust automatically.
Driven gear increases the critical piece of torque as main reducing gear part, the landing slow-speed of revolution.It is to rely on the number of teeth
Gear more than few gear band number of teeth realizes deceleration, and during automobile normal running, the rotating speed of motor is generally higher, by subtracting
Fast driving box is reduced, then rotating speed declines, and moment of torsion is necessarily increased, and also increases the transmission of deceleration case primary transmission mechanism
Load.So, a main reducing gear is set before the differential mechanism of power right driving wheel shunting to the left, can be made before main reducing gear
The moment of torsion of the motor transmission in face reduces, while also reducing the size and quality of motor, and manipulates sensitive laborsaving.It is of the invention real
Apply in example, the gear ratio range of driving gear 3 and driven gear 5 is 1:3.33-9.73 between；Driving gear 3 and driven gear 5
Modulus is between 2-6 mesh；The gear upper thread and axis section line angle of driving gear and driven gear are between 10--30.Wherein
The material of driven gear 3 and driving gear 5 is 19GrMoTiHH.
The manufacturing process of driving gear and driven gear is：1st, medium carbon alloy steel is selected：40Cr, 42CrMo, 35CrMo,
0.1% ~ 1% complex silicon carbide is added in smelting process（Phosphorus alkene and carborundum are ground to form again after 1300 degree of high temperature above calcinings
Powder body）, strictly require control in 12 × below 10-6 the oxygen content of pinion steel；2nd, in Quenching Process of Gear Steel, add
Residual Aluminum Content reaches crystal grain thinning in 0.01% ~ 0.1% rare metal yttrium and rare metal Cerium 0.05% ~ 0.2%, control steel,
>=6 grades of grain size requirement is so as to reach low-noise long-life purpose.
The present invention changes existing pure motorized motions case multi-stage gear structure, is rotated using single-stage helical teeth, exports bigger
Loss between the lower dry sound of moment of torsion, reduction gear to power, improves vehicle mileage；Applied widely, production cost of the invention
Low, service life length, energy efficiency are high, with the advantage such as environmental protection, energy-conservation, low-noise.
The preferred embodiment for the present invention is explained in detail above in conjunction with accompanying drawing, but the invention is not restricted to above-mentioned implementation
Mode, can also be on the premise of present inventive concept not be departed from the knowledge that those of ordinary skill in the art possess
Make a variety of changes, these changes are related to correlation technique well-known to those skilled in the art, and these both fall within patent of the present invention
Protection domain.
Many other changes and remodeling can be made by not departing from the spirit and scope of the present invention.It should be appreciated that the present invention is not
It is limited to specific embodiment, the scope of the present invention is defined by the following claims.
