Abstract
The utility model discloses an electric four-wheel drive vehicle dynamic system, which comprises a front axle transmission, a rear axle transmission, a driving motor, a front drive shaft and a rear drive shaft, wherein the front axle transmission is connected to a front axle and the rear axle transmission is connected to a rear axle. The electric four-wheel drive vehicle dynamic system is characterized in that a torque changing device is arranged between an output end of the driving motor and an input end of the front and the rear drive shafts. On the premise of meeting requirements of power output, the dynamic system not only guarantees the highest speed of the integral vehicle but meets requirements upon climbing, thereby enabling the four-wheel drive vehicle to realize better service performance and to meet requirements of customers.
Description
Technical field
The utility model relates to the vehicle technology field, specifically relates to a kind of power system of electric four-wheel drive vehicle, and it can be used for various electric four-wheel vehicles, casual electric car, vehicle for hunting.
Background technology
Along with the development of battery-driven car, people are more and more higher to the performance requriements of battery-driven car, do not satisfied customer's requirement with the configuration of present routine.Battery-driven car four-wheeled power system for example, the four-wheeleds that each vast electronic factory produced etc. are climbed unable otherwise F-Zero is fast, otherwise climb powerful and F-Zero is slow, thus the out of reach customer requirement.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of electric four-wheel drive vehicle power system is provided, this power system is satisfying under the situation of takeoff output, not only guarantee the F-Zero of car load but also reached the requirement of climbing, make four-wheel drive vehicle that in-use performance preferably be arranged, can satisfy client's demand.
In order to realize above-mentioned technical purpose, the utility model is realized by following technical scheme:
Power system described in the utility model, comprise the propons change-speed box that is connected on the front wheel spindle, be connected rear axle transmission, drive motor on the hind axle, and front propeller shaft and rear propeller shaft, it is characterized in that: between the input end of the mouth of drive motor and front propeller shaft and rear propeller shaft, be provided with the moment converting means.
Described moment converting means is the combination of auxiliary gear box and gear driving pair, and the input end of described auxiliary gear box links to each other with the drive motor mouth, and the mouth of described auxiliary gear box is connected with front propeller shaft and rear propeller shaft respectively by gear driving pair.
Described propons change-speed box and rear axle transmission are and can change axial crowngear case.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has auxiliary gear box and gear driving pair combination as the moment converting means owing to increasing between Transmissions such as drive motor and front and back transmission shaft, by the moment converting means make input decide moment be transformed into can be according to actual needs variable torque, thereby solved four-wheel drive vehicle climbing power and climbing contradiction between speed problem when climbing in the prior art effectively, guarantee the F-Zero of four-wheel drive vehicle when climbing and the requirement of climbing power effectively, had in-use performance preferably.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Fig. 1 is an electric four-wheel drive vehicle power system structural representation described in the utility model.
The specific embodiment
As shown in Figure 1, electric four-wheel drive vehicle power system described in the utility model, comprise the propons change-speed box 1 that is connected on the front wheel spindle, be connected rear axle transmission 2, drive motor 3 on the hind axle, and front propeller shaft 4 and rear propeller shaft 5, be provided with moment converting means 6 between the input end of the mouth of drive motor 3 and front propeller shaft 4 and rear propeller shaft 5, this propons change-speed box 1 is with rear axle transmission 2 can change axial crowngear case.
In the utility model, described moment converting means 6 is the combination of auxiliary gear box and gear driving pair, the input end of described auxiliary gear box links to each other with drive motor 3 mouths, and the mouth of described auxiliary gear box is connected with front propeller shaft 4 and rear propeller shaft 5 respectively by gear driving pair.
Electric four-wheel drive vehicle power system working process described in the utility model is: start drive motor 3, drive auxiliary gear box and gear transmission subtask, front propeller shaft 4 and rear propeller shaft 5 are drive disk assembly, and propons change speed gear box 1 and back axle change speed gear box 2 are used to distribute moment.
(1) when needs is climbed, select the suitable parameter of auxiliary gear box to come conversion moment according to actual needs, moment by drive disk assembly front propeller shaft 4 and rear propeller shaft 5 to being delivered to propons change speed gear box 1 and back axle change speed gear box 2, reach front-wheel 7 and trailing wheel 8 again, make it have higher output torque, thereby has stronger climbing power when making the car load climbing, to satisfy user's demand.
(2) when the needs F-Zero, select the suitable parameter of auxiliary gear box to come conversion moment according to actual needs, moment by drive disk assembly front propeller shaft 4 and rear propeller shaft 5 to being delivered to propons change speed gear box 1 and back axle change speed gear box 2, reach front-wheel 7 and trailing wheel 8 again, make it that less output torque be arranged, thereby guaranteeing has the highest moving velocity, even also it has the demand that moving velocity faster satisfies the user.
Owing in the power system of existing electric four-wheel drive vehicle, increased the moment variations device, make car load in motion, the big more scanning frequency of shelves number is fast more, the slow more but climbing power of shelves number more little scanning frequency is big more to be that moment is big more, fast and do not have climbing power with regard to having solved driving car when climbing F-Zero effectively like this, or climb powerful and problem that F-Zero is slow.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
