Description
Technical field
The utility model relates to a kind of Novel mid-mounted rear-guard two-shift automatic variable speed electric automobile, more particularly relates to a kind of power system transmission arrangement structure of Novel mid-mounted rear-guard two-shift automatic variable speed electric automobile, belongs to electronlmobil applied technical field.
Background technology
The many edges of transmission arrangement structure of current power system of electric automobile are used for traditional fuel vehicle, electronlmobil greatly is particularly had to be change a social system on original fuel vehicle platform at present, and electric automobile whole power system, particularly battery system, electric system and dynamic transfer system are larger for the impact of complete vehicle weight, if continue to use the layout type of conventional fuel oil car, to the layout difficulty of car load be strengthened, and affect vehicle performance.
Based on the demand that the transformation of the way of existing mid-trailing wheel overall bridge drive configuration fuel vehicle is electronlmobil, consider under not changing the condition of car load chassis structure as far as possible, rear axle and rear overhang structure can not do too large adjustment, and consider that electronlmobil drives the requirement of manipulation ride comfort, former car five grades of Manual transmission are no longer applicable, arrangement space as additionally increased Automatic Transmission then car load storage battery will be less, as cell arrangements is then unfavorable for whole vehicle stability to tail of body, therefore, a kind of applicable power system of electric automobile is arranged and the development for electric vehicle engineering and application is had crucial effect by power system transmission structure scheme.
Common change-gear rear axle used for electric vehicle is that drive motor is horizontal, be directly installed on rear axle reductor input shaft and overall back axle shape is in aggregates, but for this kind of structure, about 100KG is about because back axle self adds motor weight, rear axle unsprung weight is comparatively large, is unfavorable for that the stability of car load travels.And if the fixing single speed of employing tradition is than change-gear rear axle, then require that motor has higher power, output speed and output torque.
In existing placement process, a lot of problem will be run into, such as:
1, during the volume miniaturization of two-shift automatic variable speed back axle speed-changing mechanism, back axle speed-changing mechanism diameter will determine the height dimension of the liftoff nadir of car load, if this mechanism's diameter is greater than the diameter of former fuel vehicle back axle speed-changing mechanism, then car load will lower than former fuel oil vehicle by performance;
2, during two-shift automatic variable speed back axle speed-changing mechanism weight lightness, compared to former fuel vehicle back axle speed-changing mechanism, add one grade of speed change, weight increases to some extent, increase if weight increases the more rear axle unsprung weight that will make, affect car load and travel handling;
3, the efficiency of this transport sector.Electronlmobil affects larger because of self electric quantity and car load, as polygamy battery increase electricity then complete vehicle weight will increase, affect car load travelled distance and load-carrying, as institute's power distributing amount reduces relatively, then self electric quantity reduces impact traveling range, and the transmission efficiency height of whole transmission system, considerable influence will be travelled to car load.
Utility model content
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of Novel mid-mounted rear-guard two-shift automatic variable speed electric automobile with high performance-price ratio power system layout and power transmission solution.
To achieve these goals, the technical solution of the utility model: a kind of Novel mid-mounted rear-guard two-shift automatic variable speed electric automobile, can be changed a social system by fuel-engined vehicle, its wheel including chassis and drive this chassis, in the middle part of described chassis, suspension has motor, the output shaft of this motor is connected with two-shift automatic variable speed case, and the mouth of described two-shift automatic variable speed case is connected with the rear-axle differential transmission of power be located on the back axle of described chassis by the universal joint cross transmission shaft that is longitudinally arranged; Also include and be arranged in former machinery space and the power accumulator being in base plate electric machine and transmission shaft-side position, this power accumulator by a controller for described motor and the meter system of being located at front portion, chassis provide electric energy.
Further, described motor by rubber mounting in described chassis midway location; Described power accumulator is provided with and can carries out with outside civil power the charger that is electrically connected; At described power accumulator by a BMS control linkage.
The beneficial effects of the utility model: fix single speed than on change-gear rear axle basis in tradition, select two-shift automatic variable speed back axle, and under retaining the compact advantage of this two-shift automatic variable speed back axle self structure, back axle input shaft is changed into longitudinal, and increase a universal joint cross transmission shaft and be connected on motor, motor is fixed in the middle part of chassis, thus alleviate rear axle unsprung weight, move after decreasing conventional engines transmission gearbox motor position, power accumulator can arrangement space be increased, antero posterior axis load diatibution and complete vehicle structure are taken into account completely, there is very high cost performance.
