Description
Technical field
Patent of the present invention is related to a kind of technical field of transport facilities, a kind of specific electric car rollover prevention structure.
Background technology
In recent years, electric car is favored by more and more consumers, and electric car is flexibly compact, increasingly popularizes, and it brings
Safety problem it is also more and more concerned, existing carrying, loading are with middle-size and small-size high speed, low-speed electronic three-wheeled electric four-wheel in height
It is in light weight because vehicle body is narrow in speed traveling, when being uneven occurs in road surface or minor radius is taken a sudden turn, because center of gravity is unbalance or
Component effect is centrifuged, causes vehicle easily to be turned on one's side, so that causing security incident.
The content of the invention
The present invention will be to overcome above technical problem, there is provided a kind of structural manufacturing process is simple, easily make, ensure that passenger vehicle,
A kind of electric car rollover prevention structure of security when load-carrying vehicle is turned.
In order to solve the above technical problems, technical scheme provided by the invention is：It is described including rear axle support, rocking arm, support
The rocking arm connecting shaft for playing connection function is provided between rear axle support and rocking arm, the support is provided with rocking arm anchor ear, described to shake
Arm is actively socketed in the rocking arm anchor ear on support, and the abrasionproof for preventing that rocking arm from wearing is provided between the rocking arm anchor ear and rocking arm
Set, described rear axle support are fixed on the back axle of electric car, and the support is fixed on electric motor vehicle tail support body.
Preferably, the rocking arm is using No. 45 steel are quenched or 20,40Cr modifier treatment.
Preferably, the wearing bush is made of nylon material.
Preferably, the rear axle support, support, rocking arm anchor ear are made using material Q235 die moulds.
Preferably, rocking arm connecting shaft is made using material Q235 Vehicle Processings.
The present invention has advantages below：The present invention is simple in construction, facilitates installing/dismounting, material therefor cost is cheap, rocking arm
Flexibly it is connected between rear axle support, support, effectively can prevents vehicle from turning on one's side.
Brief description of the drawings
Fig. 1 is a kind of scheme of installation of electric car rollover prevention structure of the present invention.
Fig. 2 is a kind of structural representation of electric car rollover prevention structure of the present invention.
Fig. 3 is a kind of specific implementation schematic diagram of electric car rollover prevention structure of the present invention.
As shown in the figure：1st, rear axle support, 2, rocking arm, 3, support, 4, rocking arm connecting shaft, 5, rocking arm anchor ear, 6, wearing bush, 7,
Back axle, 8, afterbody support body, 9, wheel, 10, leaf spring.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
A kind of electric car rollover prevention structure as shown in the figure, it is characterised in that：Including rear axle support 1, rocking arm 2, support 3, institute
The rocking arm connecting shaft 4 for being provided between rear axle support 1 and rocking arm 2 and playing connection function is stated, the support 3 is provided with rocking arm anchor ear 5,
The rocking arm 2 is actively socketed in the rocking arm anchor ear 5 on support 3, and being provided between the rocking arm anchor ear 5 and rocking arm 2 prevents rocking arm 2
The wearing bush 6 of abrasion, described rear axle support 1 are fixed on the back axle of electric car, and the support 3 is fixed on electric motor vehicle tail frame
On body.
The rocking arm 2 uses No. 45 steel quenched or 20,40Cr modifier treatment.
The wearing bush 6 is made of nylon material.
The rear axle support 1, support, 3, support, 5, rocking arm anchor ear is made using material Q235 die moulds；3rd, rocking arm
Connecting shaft is made using material Q235 Vehicle Processings.
When vehicle takes a sudden turn, outside leaf spring is declined by gravity, and inner side leaf spring rises, and the present invention allows inside and outside leaf spring synchronization work
Make, inside and outside leaf spring is highly consistent when turning, the center of gravity of vehicle is effectively protected not toward side skew or the skew of minimum range
The security standpoint of vehicle angle of heel has been demonstrate,proved, will not have been turned on one's side.
Vehicle can cause the certain height of wheel lift when turning, away from bend outboard wheels due to the presence of centrifugal force
Interior outer panel spring is connected by rocking arm and rear axle support, when being movably connected in turning of support, is outside by degree, this structure
Wheel provides a downward power, ensures that wheel will not turn on one's side.
Described above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
