Description

Multi-connecting-rod intelligent adjusting suspension bracket for electric vehicle

Technical Field

The utility model relates to an electric motor car accessory technical field, concretely relates to electric vehicle is with many connecting rods intelligent regulation mounted frame.

Background

The existing electrically-driven vehicle generally adopts a design of one main wheel and two auxiliary wheels to prevent the vehicle from toppling over in the aspect of the balance problem of vehicle operation; in operation, to ensure smooth operation of the vehicle, conventional rigid suspension systems are employed, simply adding springs to dampen ground-to-vehicle vibrations. In the design, the suspension system is in the middle position of the rear side of the electrically driven vehicle, and the two auxiliary wheels are placed on the outer side of the rear side of the vehicle.

The traditional suspension system is mainly used for driving vehicles on the ground with flat road conditions and driving on inclined or uneven terrain, so that the gravity center of the electrically driven vehicle is shifted. When the electrically driven vehicle runs on uneven ground, the electrically driven vehicle deflects to one side of the vehicle and is mainly supported by one of two auxiliary wheels behind the vehicle to prevent the vehicle from toppling over, one of the auxiliary wheels can bear the impact force and the weight of the vehicle when the vehicle deflects, and the auxiliary wheel is inclined laterally and easily causes skidding. When the vehicle runs on the sunken ground, the rear wheels fall and are suspended, the two auxiliary wheels bear impact force simultaneously, the auxiliary wheels vibrate up and down, and the two auxiliary wheels support the gravity of the vehicle. When the electrically driven vehicle runs from an inclined or uneven ground to a flat ground, the problem of shock vibration caused by sudden contact between the rear wheels and the ground occurs. In a word, the traditional suspension mechanism can generate large vibration impact when the ground is uneven or the height of the ground is uneven, so that the electrically driven vehicle cannot walk stably and even topples over, and the two auxiliary wheels are easily worn and damaged by fatigue.

At present, the elastic independent suspension system is more advanced in China, the gravity center of the suspension mechanism is reduced under the action of the gravity of the chassis and a load, and the spring damper bears certain force, so that the influence can be weakened, certain vibration is absorbed, and the impact vibration cannot be avoided.

In the structure of the traditional rigid suspension and elastic independent suspension system, auxiliary wheels are mainly and independently fixed on two sides of an electrically driven vehicle and are exposed outside. The auxiliary wheel is completely independent from the rear wheel in movement, is only used as one of auxiliary parts for preventing the vehicle from inclining when the road surface is uneven, and cannot timely and synchronously adjust the uneven running of the vehicle caused by the up-and-down or inclining action of the rear wheel. The auxiliary wheel has no adjusting function, the shaft is easy to bend due to insufficient holding power (shaft is not moved), and the impact is rigid. In the traditional rigid suspension and elastic independent suspension system structure, the rear wheel is positioned in the middle of the electric vehicle, and a plurality of devices such as a control handle, a transmission motor, a speed change gear and the like are arranged on the rear wheel, so that the main body space of the electric vehicle is occupied in design, and the actual operation use space of an operator is reduced.
