Background technology
Electronlmobil in recent years, electro-tricycle due to its environmental-protecting performance and the development of cheap usage charges rapidly, back axle manufacture and the demand of battery-driven car present fast development trend, general two semiaxis that adopt a driven by motor reductor to access on diff driving back axle of back axle on battery-driven car rotate, a motor is set on this back axle, for miniwatt, the use occasion of low moment of torsion can meet the demands substantially, but for superpower, the use occasion of high pulling torque can not meet the demands on the one hand completely, in the moment of torsion transmitting on the other hand and the excessive situation of power, motor easily damages, in recent years, battery-driven car is more and more extensive as the use of loading purposes, in the situation of loading, need larger power and moment of torsion output, and also there is the trend of progressively popularizing in battery-driven car in remote mountain areas, on the hill path of the frequent uphill/downhill of needs, normal and the safety traffic of battery-driven car need to possess superpower, the output characteristic of high pulling torque, in order to adapt to this demand, traditional way is the power that increases drive motor, but general along with its volume of increase of power also will increase, bring the problem in space to corresponding rear assembling, so simple, by increasing power of motor, can not to adapt to battery-driven car completely high-power, the development need of high moment of torsion output, excessive motor volume brings the problem on space substantially cannot realize in some vehicle designs to the installation of back axle, in existing market practice, need one can export high moment of torsion, high-performance motor rear axle.
Summary of the invention
The purpose of this utility model is the technical matters of the motor rear axle horsepower output machine moment of torsion aspect that overcomes above existence, and a kind of Dual-motors Driving motor rear axle is provided.
For realizing the purpose of this utility model, the technical scheme that the utility model adopts is: Dual-motors Driving motor rear axle, comprise two semiaxis, be provided with two motors and connect respectively two semiaxis of driving, two described motors are positioned at the same side at back axle middle part, on the output shaft of two described motors, be directly or indirectly connected with driving gear, on two described semiaxis, be provided with ring gear, the driving gear jack shaft that is meshed with ring gear, in the output of two described motors, connect reductor, on the output shaft of reductor, be provided with driving gear, on two described semiaxis, be provided with ring gear, the driving gear jack shaft that is meshed with ring gear, two described motors are 120 along the circumferencial direction angle take semiaxis as axis oor 180 o.
The useful technique effect of Dual-motors Driving motor rear axle provided by the utility model is: this back axle adopts Dual-motors Driving, obviously increase compared with single motor driver output power and moment of torsion, can meet the output requirement under the special service condition such as load-carrying, upward slope, make motor be difficult for being damaged in the output situation of superpower, high moment of torsion, improve and improve the output characteristic of motor, the side that two motors are arranged on back axle middle part direction also can realize Dual-motors Driving in the situation that back axle total length is limited.This apparatus structure is simple, is easy to realize, and is applied in the performance that can significantly improve battery-driven car on motor rear axle, promotes the use of the utility model and is conducive to promote lifting and the development that battery-driven car is manufactured.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
In order better to understand and to implement the technical solution of the utility model, provide embodiment more of the present utility model at this, these embodiments, in order better to explain technical scheme described in the utility model, do not form any form restriction of the present utility model.
Dual-motors Driving motor rear axle, comprise two semiaxis, be provided with two motors and connect respectively two semiaxis of driving, two described motors are positioned at the same side at back axle middle part, on the output shaft of two described motors, be directly or indirectly connected with driving gear, on two described semiaxis, be provided with ring gear, the driving gear jack shaft that is meshed with ring gear, in the output of two described motors, connect reductor, on the output shaft of reductor, be provided with driving gear, on two described semiaxis, be provided with ring gear, the driving gear jack shaft that is meshed with ring gear, two described motors are 120 along the circumferencial direction angle take semiaxis as axis oor 180 o.
By reference to the accompanying drawings the specific embodiment of the present utility model is described further, as shown in Figure 1, in accompanying drawing, be respectively labeled as: 1-1: motor a, 1-2: reductor a, 1-3: driving gear a, 1-4: ring gear a, 1-5: semiaxis a, 1-6: semiaxis a registration device, 2-1: motor b, 2-2: reductor b, 2-3: driving gear b, 2-4: ring gear b, 2-5: semiaxis b, 2-6: semiaxis b registration device, 3: back axle, motor a1-1 is set on back axle 3, motor b2-1, in the output of motor a1-1, connect reductor a1-2, on the output shaft of reductor a1-2, be fixedly installed driving gear a1-3, driving gear a1-3 is meshed with the ring gear a1-4 being fixedly installed on semiaxis a1-5, motor a rotarilys actuate semiaxis a rotation by driving driving gear a to rotarily drive ring gear a, on back axle, be provided with semiaxis a registration device 1-6, registration device 1-6 is that outer ring is fixedly connected on the bearing on back axle, inner ring is together with semiaxis a tight fit connection, realize the supporting and location of semiaxis a, in the output of motor b2-1, connect reductor b2-2, on the output shaft of reductor b2-2, be fixedly installed driving gear b2-3, driving tooth b2-3 is meshed with the ring gear b2-4 being fixedly installed on semiaxis b2-5, motor b rotarilys actuate semiaxis b rotation by driving driving gear b to rotarily drive ring gear b, on back axle, be provided with semiaxis b registration device 2-6, registration device 2-6 is that outer ring is fixedly connected on the bearing on back axle, inner ring is together with semiaxis b tight fit connection, realize the supporting and location of semiaxis b, in the present embodiment, two electrical axis are 180 along the circumferencial direction angle take semiaxis as axis o, two electrical axis can be 120 along the circumferencial direction angle take semiaxis as axis o, considering under overall design conditions, its angle can also be selected other any angle that can realize installation, two motors of the present utility model can adopt a controller to realize and control, also can adopt two controllers to control separately, when the adjusting of electronic differential, due to the effect of controller current limiting, limit the output torque of single motor, make single motor be not enough to drive car load, the common driving of double-motor, can realize the self-regulating function of electronic differential, both sides transmission also can adopt E-Diff to realize differential control, this back axle adopts Dual-motors Driving, obviously increase compared with single motor driver output power and moment of torsion, can meet load-carrying, output requirement under the special service conditions such as upward slope, make motor at superpower, in the output situation of high moment of torsion, be difficult for being damaged, improve and improve the output characteristic of motor, two motors are arranged on a side of back axle middle part direction, in the situation that back axle total length is limited, also can realize Dual-motors Driving.This apparatus structure is simple, is easy to realize, and is applied in the performance that can significantly improve battery-driven car on motor rear axle, promotes the use of the utility model and is conducive to promote lifting and the development that battery-driven car is manufactured.
