Abstract

The utility model relates to an electric vehicle drive system, which comprises a rear axle assembly, wherein two sides of the rear axle assembly are respectively provided with a tire assembly, a drive motor is installed on the rear axle assembly, the inner side of each tire assembly at two sides of the rear axle assembly is provided with a rear spring steel plate, a rear axle fixed plate is welded on the rear spring steel plate, a rear axle fixed U-shaped bolt passes through the rear axle fixed plate to be matched with a non-metal embedded element locking nut, so the rear axle assembly is tightly connected with the rear spring steel plate; and a shock-absorption steel plate fixed plate is welded between the rear spring steel plate and the tire assembly on the rear axle assembly. The electric vehicle drive system has beneficial effects such as: compact structure, small occupied space, small noise, small vibration, long service life and high system efficiency.

Description

A kind of drive system of electric motor vehicle
Technical field
The utility model relates to a kind of drive system of electric motor vehicle.
Background technology
At present, China's Electrical Driving System of Electrical Vehicle is main with the DC machine driving still, generally adopts from the storage battery to the power inverter again to the directed energy transfer mode of drive motor, and it exists a lot of deficiencies.Particularly, though advantages such as that DC machine has is simple in structure, steerability good, speed-regulating range width, the starting torque multiple are big, control circuit is simple relatively, cost is lower, its shortcoming is very important equally.The brush DC machine is arranged owing to exist mechanical commutation parts brush or commutator, be easy to cause spark, noise is serious with vibrations; Electromagnetic interference problem is outstanding; And the maintenance of brush or commutator is relatively more difficult, and service life is shorter, in addition; The volume of motor is very huge, causes the waste of finite space; Though brshless DC motor has overcome some defectives of brush motor, its rotor position detection difficulty, price of complete machine is quite high, and cost performance is relatively low.From the system effectiveness angle,, make vehicle when brake deceleration or downhill running, waste significant amount of energy in vain again because most system adopts the unidirectional power transmission.In addition, mechanical shock, the friction of brush, commutator etc. have also caused the reduction of system effectiveness.
Summary of the invention
It is low that the utility model will solve electric vehicle system efficient; The big Heavy Weight of volume; Problems such as noise is serious with vibrations, and service life is short, provide a kind of take up room little, noise is little, vibrations are little, service life length, the higher drive system of electric motor vehicle of system effectiveness.
The technical scheme that the utility model adopts is:
A kind of drive system of electric motor vehicle; It is characterized in that: comprise back axle assembly; Said back axle assembly both sides respectively are equipped with a tire assembly, on the said back axle assembly drive motor are installed, and the both sides of said back axle assembly all are equipped with the rear spring steel plate in the inboard of tire assembly; Be welded with the back axle adapter plate on the said rear spring steel plate, said back axle assembly through back axle fixedly U-bolt pass the back axle adapter plate and cooperate with the non-metallic insert jam nut with the rear spring steel plate and be fastenedly connected; Between rear spring steel plate and tire assembly, be welded with the vibration damper steel plate adapter plate on the said back axle assembly.
Further, said drive motor is installed on the back axle assembly through bolt.
Further, between said back axle adapter plate and the non-metallic insert jam nut flat gasket is installed.
The utility model is all fixed through modes such as welding, bolted, has increased the steadiness of back axle, has saved material and space.
The utility model is provided with and battery-driven car shock mitigation system bonded assembly vibration damper steel plate adapter plate, make battery-driven car in use shake little, noise is little.
The beneficial effect of the utility model: compact conformation, take up room little, noise is little, vibrations are little, service life is long, system effectiveness is higher.
Description of drawings
Fig. 1 is the structure upward view of the utility model.
Fig. 2 be among Fig. 1 A-A to cutaway view.
The specific embodiment
Come the utility model is further specified below in conjunction with specific embodiment, but the utility model is not confined to these specific embodiment.One skilled in the art would recognize that the utility model contained in claims scope all alternativess, improvement project and the equivalents that possibly comprise.
Referring to Fig. 1, Fig. 2; A kind of drive system of electric motor vehicle; Comprise back axle assembly 3; Said back axle assembly 3 both sides respectively are equipped with a tire assembly 1, on the said back axle assembly 3 drive motor 5 are installed, and the both sides of said back axle assembly 3 all are equipped with rear spring steel plate 2 in the inboard of tire assembly 1; Be welded with back axle adapter plate 4 on the said rear spring steel plate 2, said back axle assembly 3 through back axle fixedly U-bolt 6 pass back axle adapter plate 4 and cooperate with non-metallic insert jam nut 7 with rear spring steel plate 2 and be fastenedly connected; Between rear spring steel plate 2 and tire assembly 1, be welded with vibration damper steel plate adapter plate 9 on the said back axle assembly 3.
Said drive motor 5 is installed on the back axle assembly 3 through bolt.
Between said back axle adapter plate 4 and the non-metallic insert jam nut 7 flat gasket 8 is installed.
The utility model is all fixed through modes such as welding, bolted, has increased the steadiness of back axle, has saved material and space.
The utility model is provided with and battery-driven car shock mitigation system bonded assembly vibration damper steel plate adapter plate 9, make battery-driven car in use shake little, noise is little.
