Description
Technical field
The present invention relates to the electrobus parts, the mid-electric motor coach chassis of a kind of specifically drive motor.
Background technology
Along with the needs of the crisis and the environmental protection of the energy, the development of electrobus is irresistible.The chassis layout of electrobus has different differences with the regular fuel car, cancellation exhaust system and fuel oil system, traditional cooling system, except original storage room, projects such as battery pack, controller and a plurality of helper motors have also been increased, newly-increased project is compared with the space of equal fuel vehicle, needs to increase the arrangement space of 20-30%.And according to the restriction of " vehicle rear overhang length must not surpass 65% of wheelbase; maximum must not be above 3.5 meters " of " GB7258 self-propelled vehicle safe in operation engineering factor ", satisfy simultaneously that passenger vehicle is empty fully loaded, bridge desirable axle load ratio in front and back is 40%: 60% requirement, to the proposition of the chassis layout design of electrobus a difficult problem.
Domestic electrobus all adopts motor preposition or rearmounted design arrangement scheme at present, and there is following problem in this scheme:
1, adopts the design of traditional fuel oil passenger-carrying chassis, the space problem of parts such as the drive motor of very difficult solution electrobus, battery pack, controller, particularly be difficult to satisfy the space requirement per capita of storage room regulation, and the scantling of structure of these arrangements of components spaces and car load is the relation of a pair of contradiction;
2, in the scope of limited contour structure size, wish that battery arrangement is The more the better on the one hand, the volume that needs to solve the storage room of passenger vehicle on the other hand reaches laws and regulations requirement, also need take into account under automobile zero load, the fully loaded situation simultaneously, the axle load ratio of front and back bridge satisfies the ideal designs requirement, thereby guarantee the delelivered payload capability of electrobus and every performance figure of electrobus, traditional design method is difficult to satisfy.
3, the drive motor of common electrobus is prepended to propons front (being motor preposition), in comparative example 1 (see figure 5), transmission shaft will run through propons to rear driving axle, not only increase the length of transmission shaft and take the vehicle frame volume inside, and the axle load of front and back bridge 40%: 60% the ratio more desirable than not reaching, general ratio is 45-50%: 55-45%, force of inertia reach when very easily causing the electrobus emergency braking, the moment load of front-wheel list tire sharply increases, and increases the possibility of blowing out thereby exist, the braking force of front brake is not enough, drawbacks such as the operational stability difference that turns to.And controller, power battery pack, helper motor, storage room etc. can only be arranged in vehicle frame both sides and vehicle rear, and the chassis annex is arranged in the both sides of vehicle frame inside and transmission shaft, to the arrangement space minimizing 20-30% of electrobus.
4, the drive motor of common electrobus is placed on back axle back (being motor postposition), as comparative example 2 (see figure 6)s, though overcome the drawback of preposition motor, utilized the inner space in workshop, controller, power battery pack, helper motor can be arranged in vehicle frame inside and both sides, for the axle load specific energy of front and back bridge reaches 40%: 60% desirable ratio, power battery pack must be arranged to front part of vehicle, cause the locus of storage room restricted even do not had, and the middle part of vehicle frame need to strengthen greatly.Simultaneously, be subjected to the restriction of " vehicle rear overhang length must not surpass 65% of wheelbase, maximum must not above 3.5 meters ".Between the bridge, the space was minimum before and after not only the storage room of vehicle can only be arranged in, and for the safety of power battery pack with change comfort feature, can only be arranged in the outside about vehicle frame.Therefore, drive motor is placed on the back axle back, has reduced the space availability ratio of vehicle frame inside and rear overhang virtually.
Summary of the invention
The purpose of this utility model is in order to address the above problem, provide a kind of simple in structure, space availability ratio is high, satisfies " GB7258 self-propelled vehicle safe in operation engineering factor ", the mid-electric motor coach chassis of favorably situated drive motor.
Technical scheme comprises vehicle frame, described vehicle frame is provided with drive axle and propons and/or back axle, drive motor also is housed in the described vehicle frame, and drive motor is connected with drive axle through speed change system, transmission shaft successively, and described drive motor is installed between the propons or back axle on drive axle and the vehicle frame.
Described drive axle is between propons and back axle, and described drive motor is between propons and drive axle and near drive axle.
Described drive axle is between propons and back axle, and described drive motor is between drive axle and back axle.
Described vehicle frame is provided with the drive axle of propons and double as back axle, and described drive motor is between propons and drive axle and near drive axle.
Described vehicle frame is provided with the drive axle and the back axle of double as propons, and described drive motor is between drive axle and back axle and near drive axle.
Pass through the comparison of arranging, find that electric motor coach chassis has following characteristics with traditional fuel oil passenger-carrying chassis:
1, a plurality of helper motors can independently be arranged and turn round;
2, battery pack, controller can be controlled by the mode that is flexible coupling at a distance;
3, drive motor is compared with fuel engines, and is simple in structure, and oad is little.
Therefore, consideration is mid-with drive motor, so both solved the spatial destribution problem of the annex such as battery pack, controller, helper motor of electrobus, guarantee the volume space of the storage room of electrobus again, also solve the difficult problem that arbitrary axis is arbitrarily arranged in pairs or groups apart from the front and back axle load ratio of electrobus simultaneously, thereby guarantee every performance figure of electrobus car load.
Because different model electric car passenger vehicle forerunner or rear-guard is multi-form, and the drive axle different situations of double as propons or back axle sometimes, well-designedly go out the different mid-schemes of drive motor, can make the inner space of vehicle frame allow out and use for parts such as storage room, controller, power battery pack, chassis annex, helper motors.
Can carry out appropriate design as required for the layout of other parts beyond the drive motor on the vehicle frame in the utility model, be not particularly limited here, as long as observe the mid-principle of drive motor.Described other parts except that drive motor also are not limited to the major part pointed out in the literary composition.
Beneficial effect:
1, by drive motor is mid-, the single axle transferring power, solved the problem of the chassis arrangement space deficiency of electrobus, can vacate the actv. space and make original parts such as storage room, and newly-increased parts such as controller, power battery pack, helper motor etc. obtain fully reasonably arranging under the situation of finite space.
2, drive motor is mid-to make the reasonable arrangement of other each parts can guarantee that the axle load specific energy of front and back bridge reaches desirable 40%: 60%, and meets every safety specifications of " GB7258 self-propelled vehicle safe in operation engineering factor " regulation.
3, can reach maximum battery arrangement amount, and guarantee the space per capita of the storage room of regulation.
