Electric cars bearing maintenance and care of a change in technique

Bearing on electric vehicles is equivalent to the joint to the us, in the process of electric driving, bearing can greatly associated peace when we ride safe coefficient. About electric vehicles, the greater the power of peace bearing level has the higher request, in the process of driving bearing any damaged or if the attack using nonstandard status, must be repaired in time, because this relationship to our late ride of life and peace. Electric cars bearing is an important component of the electric vehicle. Its main function is to support the mechanical rotator, reduce the coefficient of friction in the process of the movement, and guarantee its rotation accuracy. By the frictional properties of motion elements, bearing can be divided into two categories, the rolling bearing and sliding bearing. Once the rolling bearing standardization, seriation, but compared with sliding bearing radial size of it, the vibration and noise is bigger, the price is higher also. Bearing damage conditions: 1, the bearing itself quality problem, rigidity is not up to standard, material with poorly! 2, bearing exposing bad water easily, for example, the front wheel on the right side bearing; Motor end cover closed without brake bearing) With oil seal is damaged, the water bearing inner butter wash off, cause smooth and rust, increasing friction bearing worn 'apart'. 3, such as shock hit or wheel shaft rod hardness is not enough to bending deformation, can make the bearing tend to stress in the process of operation, will be 'inner circle' and grinding 'outer circle', make the shaft accept force without an average damage! 4, inaccurate bearing hole processing precision loss, bearing small deformation, running friction increases, cause premature bearing wear 'fighting'! Bearing in excessive damage conditions, tilt wheel can attack, then rush partial formation vehicles on the road, this is because the land bearing capacity in a certain direction, to form the electric vehicles is difficult to handle in the process of driving direction. Serious may attack the wheels is shattered, if the vehicle is in a state of high speed that the results would not imagine, so it is necessary to timely change the damaged bearing. Change to pay attention to matters: 1, check the end cover change of bearing oil seal, if oil seal blockade is bad please give along with all the change! 2, the factory bearing inside smooth oil little or no oil, bearing oil seal, please pry appropriate smooth add oil! ! 3, if the bearing hole loose this kind of trouble, think of safe sex, dealing with the circle or the motor end cover to give change! 4, the end of the bearing assembly, please put the wheel impending, check the sensitive wheel can run smoothly, without effort or card lag phenomenon, if any, may be bearing no in place, please device again! Or you will sweep don, insensitive, forced by bearing on 'paralysis' again soon! 5, and inform the customer as far as possible not to have a ride in the middle of the water, in order to avoid water rust. Electric cars bearing moved after a long time, it is easy to damage, not being of turning, turning sound, more for the bearing pressure, repair as soon as possible to avoid small problem into a big trouble.
