Description

Universal joint wire flexible shaft linking wheel drive generator

technical field

The utility model relates to a universal joint steel wire flexible shaft for linking a wheel-driven generator of a new energy pure electric vehicle.

Background technique

New energy pure electric vehicles have advanced technology, especially pure electric vehicles, with linear acceleration and smooth thinking, which are unmatched by traditional vehicles.

Advantage 1 of new energy vehicles: environmental protection

The second advantage of new energy vehicles: saving money

Advantage 3 of new energy vehicles: low noise

Advantage 4 of new energy vehicles: energy saving

However, there are also many problems with new energy vehicles. First, the technology is immature, especially the battery life of pure electric vehicles still cannot meet the specific needs of use.

For new energy pure electric vehicles, we can divide it into two parts: unsprung mass and sprung mass. If the unsprung mass is defined, it refers to the mass that is not supported by the elastic elements in the suspension system, generally including wheels, springs, shock absorbers and other related components, and the sprung mass is naturally the rest of the vehicle. Mass, generally including frame, power system, power battery, transmission, occupants, etc., increasing the unsprung mass is extremely detrimental to comfort and handling.

For ordinary civilian vehicles, some relatively light materials such as aluminum alloys are often used to make suspension components to reduce the unsprung mass and improve the response speed of the suspension. However, the hub generator just increases the unsprung mass. At the same time, it also increases the moment of inertia of the wheel hub, which is detrimental to the handling performance of the vehicle. In addition, the hub generator works in a harsh environment and faces many influences such as water, dust, and mud.
