Abstract
The utility model relates to a dual-motor differential rear axle. The dual-motor differential rear axle comprises a main motor, an auxiliary motor and a rear axle transmission assembly, wherein the main motor is directly connected with the rear axle transmission assembly; and the auxiliary motor is connected with the rear axle transmission assembly through a one-way overrunning clutch. The dual-motor differential rear axle has the benefits as follows: the drive power is two times that of a single-motor drive rear axle; the single-motor single-power drive mode can be also realized under light load at the same time, and the other motor is in an idle state; and the switching operation between a dual-power mode and a single-power mode can be adjusted according to the actual situation, so that the motors can work with highest efficiency and are protected, the service lives of the motors are prolonged, and power is saved.
Description
Technical field
The utility model relates to a kind of double-motor differential speed rear axle.
Background technology
Electronic three, four-wheeled only has a drive motor usually, the load-carrying ability of, four-wheel electronic three for improving, can only improve the power of drive motor, but adopt the power consumption of high-power driving motor high, be unfavorable for improving travelled distance electronic three, four-wheel, and the driving circuit cost of high-power driving motor is higher, is unfavorable for controlling integral vehicle cost.
The utility model content
Technical problem to be solved in the utility model is: a kind of double-motor differential speed rear axle is provided, and power-handling capability is strong, uses flexibly power saving.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of double-motor differential speed rear axle, comprise main motor and helper motor, back axle drive assembly, main motor directly is connected with the back axle drive assembly, and helper motor is by mono-directional overrun clutch and back axle drive assembly.
The back axle drive assembly comprises the first gear wheel shaft, the second gear wheel shaft, differential assembly, left and right half, brake assembly, one end of the first gear wheel shaft is connected with mono-directional overrun clutch, the other end of the first gear wheel shaft is connected with main motor, the first gear wheel shaft and the second gear wheel shaft pass through gear transmission, the second gear wheel shaft and differential assembly pass through gear transmission, differential assembly is connected with left and right half respectively, and left and right half is connected with brake assembly respectively.
Mono-directional overrun clutch is one-way wedge type overdrive clutch.
Have an axle miniature gears on the first gear wheel shaft, have two axle miniature gearss and two axle big gear wheels on the second gear wheel shaft, two axle big gear wheels and the second gear wheel shaft interference fit, helper motor is connected with mono-directional overrun clutch by adapter shaft.
The beneficial effects of the utility model are: power-handling capability is the twice of single motor-driven rear-axle drive power; simultaneously in the situation that underloading also can realize the single motor single power driven; an other motor remains static; can regulate switching between double dynamical and the single-power according to actual conditions; the situation that makes motor be in full blast is worked; the protection motor, the service life of prolongation motor, power saving.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of mono-directional overrun clutch of the present utility model;
Fig. 3 is the structural representation of the first gear wheel shaft of the present utility model;

Among the figure, 1. mono-directional overrun clutch, 2. the first gear wheel shaft, 21. 1 axle miniature gearss, 3. adapter shaft, 4. the second gear wheel shaft, 41. 2 axle miniature gearss, 42. 2 axle big gear wheels, 5. differential assembly, 6. right axle shaft, 7. left half axle, 8. brake assembly.
The specific embodiment
Shown in Fig. 1,2,3 and 4, a kind of double-motor differential speed rear axle comprises main motor and helper motor, back axle drive assembly, and main motor directly is connected with the back axle drive assembly, and helper motor is by mono-directional overrun clutch 1 and back axle drive assembly.
The back axle drive assembly comprises the first gear wheel shaft 2, the second gear wheel shaft 4, differential assembly 5, left and right half 7,6, brake assembly 8, one end of the first gear wheel shaft 2 is connected with mono-directional overrun clutch 1, the other end of the first gear wheel shaft 2 is connected with main motor, the first gear wheel shaft 2 and the second gear wheel shaft 4 pass through gear transmission, the second gear wheel shaft 4 passes through gear transmission with differential assembly 5, differential assembly 5 is connected with left and right half 7,6 respectively, and left and right half 7,6 is connected with brake assembly 8 respectively.
Mono-directional overrun clutch 1 is one-way wedge type overdrive clutch.
Have on the first gear wheel shaft 2 and have two axle miniature gearss 41 and two axle big gear wheels, 42, two axle big gear wheels 42 and the second gear wheel shaft 4 interference fit on an axle miniature gears 21, the second gear wheel shafts 4, helper motor is connected with mono-directional overrun clutch 1 by adapter shaft 3.
The utility model working process is such,
When main motor, helper motor move simultaneously, drive the first gear wheel shaft 2, axle miniature gears 21 on the first gear wheel shaft 2 drives 42 rotations of two axle big gear wheels, two axle big gear wheels 42 and the second gear wheel shaft 4 are interference fit, drive 4 rotations of the second gear wheel shaft, two axle miniature gearss 41 on the second gear wheel shaft 4 drive with differential assembly 5 differentials and cooperate.In the time of should only having together main motor operation, also can realize above-mentioned functions, but owing to having used one-way wedge type overdrive clutch, the auxiliary electrical chance remains static, and can not produce the reverse impact electric current, also can not consume electric energy, has also protected simultaneously motor.
