Description
Technical Field
The invention belongs to the technical field of automobiles, relates to an electric drive assembly, and particularly relates to an integrated wheel-side driving device on an independent suspension.
Background
With the increasing severity of the world energy crisis and air pollution, people pay more and more attention to the development of new energy automobiles, and in China, in order to promote the development of energy automobiles, a series of policies and regulations are established in China, and the development of new energy automobiles is out of gear. In the passenger train field, [ electric ] motor coach has also obtained corresponding development, however, present [ electric ] motor coach only makes and has changed traditional fuel power form into electronic form, do not obtain corresponding development on passenger train overall structure, along with the quick development of passenger train technique, people are more and more high to the requirement of the travelling comfort of taking of passenger train, present [ electric ] motor coach floor height, it is inconvenient that the passenger gets on or off the bus, especially old and child passenger, in addition, present [ electric ] motor coach, the passageway between the seat of both sides is narrow, the passenger passes through inconveniently, therefore, low floor, the wide electricelectric passenger train of big cross the way is the inevitable trend of future development.
For this reason, a person skilled in the art realizes a form of independent suspension and wheel-side drive, and further reduces the volume of the drive assembly, for example, a steering independent suspension for a wheel-side motor-driven electric passenger car disclosed in chinese patent (No. CN205523661U), which comprises a left suspension, a right suspension, a steering tie rod, a steering rocker, a steering locking cylinder and a steering damper, wherein the steering rocker is connected to a car frame, two sides of the lower end of the steering rocker are respectively connected to the left suspension and the right suspension through two steering tie rods, the left suspension and the right suspension are symmetrically arranged on two sides of the car frame, the left suspension and the right suspension have the same structure, the patent is that a drive motor is arranged at a wheel position of the passenger car, the drive motor is located on one side of an output shaft of a speed reducer, the speed reducer is fixed on a support arm, the output shaft of the speed reducer passes through a center hole of the support arm to connect with a wheel-side structure of the passenger car, and drive wheels of the wheel-side structure to rotate, the realization is to the drive of passenger train, and the support arm passes through steering linkage and connects to turn to the rocking arm, realizes turning to the function, and the distance between two reducers is the passageway width of passenger train promptly to reach increase passenger train car inner space, reduce the purpose of passenger train floor height.
However, in the above patent, the reducer is fixed on the support arm, the driving motor is located at one side of the output shaft of the reducer, because the assembly space of the support arm is small, if the reducer is directly connected with the support arm, the connection area between the reducer and the support arm is inevitably small, the overall mass of the reducer and the motor assembly and the moment acting force generated by the vehicle vibration are all borne by the connection part of the reducer and the support arm, the stress area is small, the reducer is only stressed in one corner of the side part of the reducer, the stress on the side wall of the reducer housing is inevitably uneven, and the reducer housing is generally made of an aluminum housing with low strength for reducing the weight, therefore, the direct connection between the reducer and the support arm on one hand easily causes the deformation due to the local excessive stress, thereby causing the risk of oil leakage of the reducer, on the other hand, the center of gravity of the reducer housing is easily deviated due to the long-term local stress, the stress at each joint is uneven, so that the connection strength is reduced, and the fastening piece is loosened to form potential safety hazards.
In addition, the wheel-side motor in the prior art mostly adopts a disc-type motor, and is small in size and high in power, so that the wheel-side motor is suitable for a wheel-side driving structure on a passenger car, the driving motor is connected to a reducer shell, if an enterprise considers from the cost perspective, under the condition of sacrificing a certain space, the ordinary radial motor can be used for driving, but the reducer is not strong enough to support the radial motor with larger mass due to the adoption of an aluminum shell, and even if the internal space is sacrificed, the ordinary motor cannot be applied to the wheel-side driving.
