Description
Technical field
The present invention relates to a kind of novel Non-carrying type independent drive electric vehicle bridges.
Background technique
In recent years, since country greatly develops new-energy automobile, so that electric drive axle products application is fast-developing.And electricity drives
Dynamic bridge and the maximum difference of traditional vehicle bridge are change transmission system, increase motor and electronic control unit.Such as in commercial vehicle collection
At in the electric axle product development field of change, central motor associated mode structure, realizes electricity most commonly in traditional axle
Machine is integrated with traditional vehicle bridge, but the structural volume is larger, the quality weight under leaf spring, and transmission efficiency is not high.It is another
It is wheel motor and hub motor, the two eliminates axle housing and semi-axis structure, but manufacturing cost is relatively high, and host installs vehicle frame
Change larger, technical difficulty is big, is not easy to realize.
Summary of the invention
The present invention independently drives electric bridge bassinet structure in view of the above-mentioned problems, providing a kind of Non-carrying type, which both can solve
Central motor associated mode unsprung mass is excessive, the low disadvantage of transmission efficiency, and can optimize wheel motor and hub motor technology hardly possible
Degree is big, the high problem of manufacturing cost, while improving seriation, modular designed capacity.
Present invention provide the technical scheme that
A kind of Non-carrying type independent drive electric vehicle bridge, including vehicle frame, vehicle frame two sides are respectively equipped with one group of leaf spring, feature
It is:
A., two wheel end connecting brackets are set, are respectively equipped with steel bracket in the connecting bracket of each wheel end, each steel bracket with it is corresponding
One group of leaf spring connection；Corresponding wheel end system is connected in the connecting bracket of each wheel end, is connected in two wheel end connecting brackets
Connect the integrated carrying-type axle shell for deviateing wheel end system axis；
B. driving motor is connected and fixed on vehicle frame, driving motor output end is equipped with the gear-box and differential mechanism of integral structure, differential
The output shaft at device both ends is separately connected first universal joint, and each first universal joint is separately connected a swinging half-axle,
Each swinging half-axle other end is separately connected second universal joint, each second universal joint respectively with corresponding wheel end system
Hub spindle in system is connected.
Further technical solution are as follows:
The position that integrated carrying-type axle shell is connect with wheel end connecting bracket is arranged in steel bracket in wheel end connecting bracket, makes whole
Body bearing-type axle shell and wheel end system axis form biasing setting.
Further technical solution are as follows: integrated carrying-type axle center is additionally provided with the concave structure stepped down to differential mechanism.
Another technical solution are as follows: the position where wheel end system is arranged in the steel bracket in wheel end connecting bracket.
The present invention has the advantages that
Product can realize modularized design manufacture and installation maintenance.In design, driving is respectively independent with carrier module, in conjunction with visitor
Family demand can remodeling appropriate change, it is flexible with certain design.In manufacture, because each system structure is independent, can simultaneously into
The process and assemble of row subsystem, shortens process and assemble manufacturing process, and manufacture assembly difficulty reduces.In installation maintenance, avoid by list
A components assembly damages and causes the replacement of assembly.Motor band deceleration mechanism is fixed on vehicle frame, and gear transmission noises are opposite
Steadily, axle housing bearing system and its independence, can bear alone not influence motor driven systems from the load on wheel ground, by
Power stable structure is good.Independent drive part is installed on vehicle frame, vehicle sprung mass is belonged to.Change with the motor direct-connection type of transmission
The electric drive axle made is compared, and the unsprung mass of vehicle can be significantly mitigated, and in the case where vehicle sprung mass is constant, is mitigated under spring
Quality can promote the acceleration of vehicle and stablize maneuverability.
Detailed description of the invention
