Background technology
At present, new-energy automobile industry development is rapid, and wherein, pure electric automobile industry development makes rapid progress especially, the new forms of energy products such as pure electric sedan, passenger vehicle, lorry, special vehicle, and volume of production and marketing has all turned over several times, but pure electronic benefit electric car or rare.Due to when design chassis structure, consider high-low pressure electrically-controlled component (comprising entire car controller, DC/DC, electric hydraulic power-assisted steering pump, electric vehicle-mounted inflation pump, high-tension distribution box and low tension battery), cooling module (comprising radiator, condenser, water pump, air-conditioning compressor), electrokinetic cell assembly (comprising electrokinetic cell bag and battery management system), drive motor, electric machine controller and comprise the layout of traditional bottom disc portion on chassis and maintenance, so general truck chassis cannot meet the actual needs of pure electronic benefit electric car.Traditional bottom disc portion comprises traveling part (being made up of the vehicle frame of automobile, vehicle bridge, front and back axletree, wheel and suspension etc.), knuckle section (being made up of deflector, bearing circle etc.) and brake portion etc., belong to the known technology in car chassis field, be not described in detail.
At present, mostly most of pure electric automobile chassis arrangement structure, be simply driving engine to be replaced with drive motor, and arrange electrokinetic cell in transmission shaft both sides.But there is following problem: 1. because electrokinetic cell bag is arranged in transmission shaft both sides, so once et out of order, electrokinetic cell bag is difficult to maintenance and quick-replaceable.2. due to electrokinetic cell bag centralized arrangement, corresponding attachment point there will be concentrated load, produces with impact service life vehicle frame.
Summary of the invention
The purpose of this utility model is the deficiency in order to overcome in background technology, provides the chassis arrangement structure that a kind of structure is simple, axle load distributes rationally, is convenient to the pure electronic benefit electric car of unified management and maintenance.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of chassis arrangement structure of pure electronic benefit electric car, comprise traditional bottom disc portion, also comprise high-low pressure electrically-controlled component, cooling module, electrokinetic cell assembly, drive motor and electric machine controller; High-low pressure electrically-controlled component is arranged in the cabin of cab seat bottom, and cooling module is arranged in the forward engine room on chassis; It is characterized in that: the multiple power brick dispersed placement in described electrokinetic cell assembly are between the front and back axletree on chassis and rear overhang place.
Further improve technique scheme, described electric machine controller is arranged in above front axle.
Further improve technique scheme, described drive motor is arranged in front axle rear.
Further improve technique scheme, described electric hydraulic power-assisted steering oil pump is arranged in deflector right abaft.
Further improve technique scheme, described electric vehicle-mounted inflation pump is arranged on frame outside face.
Beneficial effect: by by the multiple power brick dispersed placement in electrokinetic cell assembly between the front and back axletree on described chassis and rear overhang place, like this, electrokinetic cell assembly periphery is unobstructed, once a certain power brick et out of order, can realize Quick overhaul and replacing.Meanwhile, heavy parts (electrokinetic cell assembly) most on chassis is arranged in middle and lower part, chassis, reduces car load center of gravity, make axle load before and after the zero load of chassis reach the 1:2 in ideal, improve the manipulation stability of car load.This arrangement structure has rational in infrastructure, and feasibility is high, and practicality is good, the advantage of good economy performance.

Detailed description of the invention
As shown in Figure 1, a kind of chassis arrangement structure of pure electronic benefit electric car, comprises traditional bottom disc portion, also comprises high-low pressure electrically-controlled component 1, cooling module 2, electrokinetic cell assembly 3, drive motor 4 and electric machine controller 5; High-low pressure electrically-controlled component 1 comprises entire car controller, DC/DC, electric hydraulic power-assisted steering pump, electric vehicle-mounted inflation pump, high-tension distribution box and low tension battery; High-low pressure electrically-controlled component 1 is arranged in the cabin of operator's compartment major-minor seat bottom, and cooling module 2 is arranged in the forward engine room on chassis; 14 power brick dispersed placement in described electrokinetic cell assembly 3 between the front axle 6 and back axle 7 on chassis and rear overhang place, i.e. the afterbody side side, middle part of vehicle frame 8 left-right longeron being all provided with five power brick, vehicle frame left-right longeron are all provided with two power brick; By the power brick of dispersed placement, electrokinetic cell assembly outer 1 is enclosed unobstructed, once a certain power brick et out of order, Quick overhaul and replacing can be realized.Meanwhile, heavy parts (electrokinetic cell) most on chassis is arranged in middle and lower part, chassis, reduces car load center of gravity, make axle load before and after the zero load of chassis reach the 1:2 in ideal, improve the manipulation stability of car load.
As shown in Figure 1, in such scheme, described electrokinetic cell assembly 3 is divided into 14 power brick (mainly in order to make electrokinetic cell assembly and the unification of interior energy-storage battery, to be convenient to management; Benefit electric system is not described in detail, belongs to technology well known in the art), single battery inclusion amasss little, lightweight, can avoid producing concentrated load to vehicle frame, meanwhile, can realize single field-strip, easy to maintenance.
As shown in Figure 1, in such scheme, described electric machine controller 5 is arranged in above front axle 6, and electric machine controller 5 is connected with vehicle frame 8, reduces to shake electric machine controller.Meanwhile, shorten the distance between drive motor 4, share a set of cooling system with drive motor 4, shorten pipeline, optimize cooling system.
As shown in Figure 1, in such scheme, described drive motor 4 is arranged in front axle 6 rear, and drive motor 4 is connected with vehicle frame, makes front axle axle load more reasonable.Meanwhile, increase drive motor 4 and back axle distance, reduce driving angle, make that drive system transmission is more smooth-going, driving efficiency is higher.
As shown in Figure 1, in such scheme, described high-low pressure electrically-controlled component 1 is arranged in the cabin of cab seat bottom.By by electric machine controller 5 and high-low pressure electrically-controlled component 1 centralized arrangement in a little space, high tension apparatus system integration degree can be made higher, and each devices function concertedness is better, meanwhile, can effectively reduce high tension cord length, reduce costs.
As shown in Figure 1, in such scheme, described electric hydraulic power-assisted steering oil pump 9 is arranged in deflector right abaft, and electric hydraulic power-assisted steering oil pump 9 is connected with vehicle frame 8, shortens and exports high pressure fuel pipe length, improve hydraulic efficiency.
As shown in Figure 1, in such scheme, described electric vehicle-mounted inflation pump 10 is arranged on chassis side rail lateral surface, and side is unobstructed, is convenient to later maintenance.Meanwhile, because electric vehicle-mounted inflation pump operationally exists swivel in inside, be arranged in frame downward, reduced center of gravity, effectively extended its service life.
Parts connection structure in this specification sheets and other part that do not elaborate are technology well known in the art.
