Description
Technical field
The present invention relates to electric car drive assembly technical fields, more particularly to Dual-motors Driving rear axle assy.
Background technique
Rear axle assy is one of the important composition component of automobile chassis system and the main building block of running gear, it rises
The important function such as driving, carrying and braking.According to country " energy conservation and new-energy automobile industrial development planning (2012-2020
Year) " the object of planning, more vehicles enterprise will necessarily select to develop new energy pure electric automobile to reduce combustion fuel consumption values；Meanwhile with
The enhancing of people's environmental consciousness, new energy pure electric automobile are increasingly subject to pursuing for masses, become the first choice and vapour of people's trip
The developing direction in vehicle future.But at present in the industrialization process of electric car, electric car single motor driving axis is deposited
Low in driving capability, bearing capacity is small, and mileage travelled is short, brakes the defects of unstable, it is difficult to meet consumer demand.
Summary of the invention
In order to overcome the above-mentioned deficiency of the prior art, the invention proposes Dual-motors Driving rear axle assys, solve existing electricity
Driving force deficiency, poor stop existing for electrical automobile single motor driving axis, the problem that bearing capacity is small and mileage travelled is short.
The present invention is achieved by the following technical solutions:
