Abstract

The utility model discloses a drive axle of an electric car directly driving a rim by multiple motors, aiming at the defects that materials and resources are wasted when the existing drive axle of theelectric car is manufactured, and noises pollute environments. The drive axle of the electric car comprises an axle; a damping spring fixed on the axle; rims fixed at two ends of the axle by nuts andbearings; wheels fixed in a groove of the rims; a protecting cover fixed outside the rims; and a brake pan fixed in the rims. The drive axle of the electric car provided by the utility model fixes the motors at the two wheels installed at both ends of the axle, wherein rotors of the motors contact with the rims of the wheels.

Description

The electric motor car driving bridge of multiple motors direct drive rim

Technical field

The utility model discloses a kind of electric motor car driving bridge of multiple motors direct drive rim, belong to the electronic product technical field, especially relevant with the electric motor car driving bridge that travels with driven by power.

Background technology

Along with the progress at full speed of science and technology, the needs of environmental protection, battery-driven car pollution-free, low noise is more and more favored.The drive axle of known battery-driven car comprises axletree, the damping spring of fixing on axletree; There is rim at two ends at axletree by nut, bearing fixing, at the groove internal fixation of rim tire are arranged; Fixed outside at rim has protecting cover; Inner face at rim is fixed with the brake pot; On axletree, be fixed with support, on support, be fixed with electrical motor, speed-changing mechanism, be connected in driving band or transmission shaft, planetary wheel, worm gear, semiaxis and axle sleeve mechanism between electrical motor and the speed-changing mechanism.Thisly existingly lean on an electric motor driven drive axle that following defective is arranged: the one, many, the Heavy Weight of the parts of drive axle, waste raw MAT'L during manufacturing, time-consuming, production efficiency is low; The 2nd, the fragile rate height of parts in travelling increases service expenditure; The 3rd, be in operation between each parts that friction force is big, in-fighting is big, horsepower output is little, wastes energy; The 4th, the vibration that a parts is in operation is big, noise big, contaminated environment.

Summary of the invention

At existing by an electric motor driven electric motor car driving bridge waste during fabrication raw MAT'L, time-consuming, production efficiency is low; Parts fragile rate height in service, increase service expenditure; In the use between each parts in-fighting big, waste energy; Defectives such as the big contaminated environment of noise, the utility model discloses a kind of electric motor car driving bridge of multiple motors direct drive rim, battery-driven car utilizes the electric motor car driving bridge of this multiple motors direct drive rim, can save great deal of raw materials during production, reduce manufacturing cost, enhance productivity; Reduce the parts loss, reduce service expenditure; Noiselessness in service, free from environmental pollution.

Taked following technical scheme for realizing the purpose of this utility model:

Make a kind of electric motor car driving bridge of multiple motors direct drive rim, the electric motor car driving bridge of this multiple motors direct drive rim comprises axletree, the damping spring of fixing on axletree; There is rim at two ends at axletree by nut, bearing fixing, at the groove internal fixation of rim tire are arranged; Fixed outside at rim has protecting cover; Inner face at rim is fixed with the brake pot; The utility model is that two wheel places of installing at the axletree two ends all are fixed with electrical motor, and the rotor of electrical motor touches mutually with the rim of wheel.

Characteristics of the present utility model are simple in structure, easy to manufacture, easy to install; Its remarkable advantage saves material, reduces manufacturing cost when being manufacturing; Minimizing damage of components in service, minimizing service expenditure; Reduce in-fighting, increase horsepower output.

Description of drawings

Further describe technical characterictic of the present utility model below in conjunction with accompanying drawing:

Accompanying drawing, the semi-sictional view structural representation of an embodiment of the utility model.

Among the figure: 1, rim 2, rotary gap 3, protecting cover 4, nut 5, bearing 6, axletree 7, tire 8, rotor 9, stator 10, damping spring 11, brake pot

The specific embodiment

As shown in drawings, 6 among the figure is axletrees, is fixed with damping spring 10 on axletree 6; Two ends at axletree 6 are fixed with rim 1 by nut 4, bearing 5, at the groove internal fixation of rim 1 tire 7 are arranged; Fixed outside at rim 1 has protecting cover 3; Inner face at rim 1 is fixed with brake pot 11; The utility model is that two wheel places of installing at axletree 6 two ends all are fixed with electrical motor 9, and the rotor 8 of electrical motor 9 touches mutually with the rim 1 of wheel.

Since the utility model will as the rotor of 2 electrical motors 9 of power directly be fixed on axletree 6 on rim 1 touch mutually, direct drive wheel 1 rotated when electrical motor rotated, and had reduced mechanical wear, can conservation of power consumption more than 20%; Save parts such as change speed gear box, transmission device, saved material during manufacturing, reduced the damage rate of parts during operation, saved service expenditure; Noiselessness in service, free from environmental pollution.
