Technical field
The present invention relates to a kind of pure electric automobile chassis arrangement, more particularly to a kind of pure electronic benefit electric car chassis arrangement.
Background technology
At present, new-energy automobile industry development is rapid, and wherein, pure electric automobile industry development even more makes rapid progress, and the new forms of energy product such as pure electric sedan, car, lorry, special-purpose vehicles, volume of production and marketing have all turned over several times, but pure electronic benefit electric car or rare.As, when chassis structure is designed, high-low pressure electrically-controlled component will be considered（Including entire car controller, DC/DC, electric hydraulic power-assisted steering pump, electric vehicle-mounted inflating pump, high-tension distribution box and low tension battery）, cooling component（Including radiator, condenser, water pump, compressor of air conditioner）, power battery assembly（Including electrokinetic cell bag and battery management system）, motor, electric machine controller and the arrangement on chassis and maintenance including traditional chassis portion, so general truck chassis cannot meet being actually needed for pure electronic benefit electric car.Traditional chassis portion includes traveling part（By the vehicle frame of automobile, vehicle bridge, axletree, wheel and suspension etc. are constituted in front and back), knuckle section（It is made up of steering gear, steering wheel etc.）And brake portion etc., belong to the known technology in automobile chassis field, be not described in detail.
At present, most of pure electric automobile chassis arrangement, is that electromotor is replaced with motor simply mostly, and arranges electrokinetic cell in power transmission shaft both sides.But there is problems with：1. as electrokinetic cell bag is arranged in power transmission shaft both sides, once so break down, electrokinetic cell bag is difficult to overhaul and quick-replaceable.2. due to electrokinetic cell bag centralized arrangement, corresponding mount point occurs concentrfated load, and vehicle frame service life is produced to affect.
The content of the invention
The invention aims in overcoming the shortcomings of background technology, there is provided a kind of simple structure, axle load distribution rationally, be easy to the chassis arrangement of pure electronic benefit electric car that is managed collectively and overhauls.
In order to solve above-mentioned technical problem, the technical scheme is that：A kind of chassis arrangement of pure electronic benefit electric car, including traditional chassis portion, also including high-low pressure electrically-controlled component, cooling component, power battery assembly, motor and electric machine controller；High-low pressure electrically-controlled component is arranged in the cabin of cab seat bottom, and cooling component is arranged in the forward engine room on chassis；It is characterized in that：Multiple battery bags in the power battery assembly are distributed across in front and back between axletree and at rear overhang of chassis.
To the further improvement of above-mentioned technical proposal, the electric machine controller is arranged in above front axle.
To the further improvement of above-mentioned technical proposal, the motor is arranged in front axle rear.
To the further improvement of above-mentioned technical proposal, the electric hydraulic power-assisted steering oil pump is arranged in steering gear right back.
To the further improvement of above-mentioned technical proposal, the electric vehicle-mounted inflating pump is arranged on frame outside face.
Beneficial effect：By the multiple battery bags in power battery assembly are distributed across in front and back between axletree and at rear overhang of the chassis, so, power battery assembly periphery is unobstructed, once a certain battery bag breaks down, can realize Quick overhaul and replacing.Meanwhile, by most heavy parts on chassis（Power battery assembly）Chassis middle and lower part is arranged in, car load center of gravity is reduced, axle load reaches in ideal 1 before and after making chassis zero load:2, improve the manipulation stability of car load.The arrangement has rational in infrastructure, and feasibility is high, and practicality is good, the advantage of good economy performance.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure, 1 is high-low pressure electrically-controlled component, and 2 is cooling component, and 3 is power battery assembly, 4 is motor, 5 is electric machine controller, and 6 is front axle, and 7 is back axle, 8 is vehicle frame, 9 is electrohydraulic steering oil pump, and 8 is electric vehicle-mounted inflating pump, and 11 is electric air-conditioning compressor, 12 is spare tyre, and 13 is power transmission shaft.
Specific embodiment
As shown in figure 1, a kind of chassis arrangement of pure electronic benefit electric car, including traditional chassis portion, also including high-low pressure electrically-controlled component 1, cooling component 2, power battery assembly 3, motor 4 and electric machine controller 5；High-low pressure electrically-controlled component 1 includes entire car controller, DC/DC, electric hydraulic power-assisted steering pump, electric vehicle-mounted inflating pump, high-tension distribution box and low tension battery；High-low pressure electrically-controlled component 1 is arranged in the cabin of driver's cabin major-minor seat bottom, and cooling component 2 is arranged in the forward engine room on chassis；14 battery bags in the power battery assembly 3 are distributed across between the front axle 6 on chassis and back axle 7 and at rear overhang, i.e., be mounted on being mounted on two battery bags on the afterbody side of five battery bags, vehicle frame left-right longeron on the middle part side of 8 left-right longeron of vehicle frame；By the battery bag of dispersed placement, make power battery assembly outer 1 enclose unobstructed, once a certain battery bag breaks down, Quick overhaul and replacing can be realized.Meanwhile, by most heavy parts on chassis（Electrokinetic cell）Chassis middle and lower part is arranged in, car load center of gravity is reduced, axle load reaches in ideal 1 before and after making chassis zero load:2, improve the manipulation stability of car load.
