Description
Technical field
The invention belongs to vehicle technology fields, refer in particular to a kind of motor middle rear wheels of electric vehicle assembly of compact.
Background technique
The structure of the electric vehicle of conventional motors middle has some unreasonable designs:
One, the replacement of synchronous belt, synchronous belt merely have to get off entire motor disassembling when replacing, but also need use
Synchronous belt, disassembly process and its complexity can be replaced by disassembling in the support rod of fixed motor, maintenance personal's heavy workload,
And operating accuracy cannot be guaranteed, the disassembly of motor and the disassembly of support rod cannot be guaranteed same when be easy to causeing installation again
The coplanar setting in the longitudinal direction with active and passive wheel is walked, and then makes to generate torque and shearing force when toothed belt transmission, reduction synchronous belt,
The using effect and service life of belt wheel or even motor and complete machine；
Two, the connection type of motor and rear chain stay, as long as any connection bolt between motor and rear chain stay occurs
It loosens, then the displacement of active synchronization belt wheel position can be all caused, because the central axis of active synchronization belt wheel is on fore-and-aft plane
Higher than the displacement of the central axes of passive and synchronous belt wheel, therefore active synchronization belt wheel cause active synchronization belt wheel with it is passive and synchronous
The distance of shaft centers of belt wheel is just short, is driven belt sag, further results in pulley, thus electric vehicle user no matter apart from destination also
How far, once motor driver and any connection bolt of rack loosen, transmission belt loosens, skids, and vehicle just can not
Continue to ride；
Three, wheel splash board, rear chain stay splash board and transmission belt splash board are all to be individually separated setting and installation, and wheel is anti-
The installation positioning of mud plate need to be fixed on axle aggregate by additional mounting bracket, need to be torn open when mounting and dismounting wheel splash board
Wheel axle aggregate is unloaded, or even the replacement for also needing the rear seat portion of disassembly electric vehicle to be just able to achieve wheel splash board, it is cumbersome；
Four, the protection of motor, the electric vehicle of present motor middle for the motor that is arranged between two wheels not
Have and carry out more appropriate either protection of blocking, the mud of ground or liquid are often thrown to motor by the rear-wheel in rolling
On, so that motor is whole unsightly, if do not cleared up motor, it just will affect the heat dissipation of motor, electric vehicle traveling
In the section for being uneven or having step, since the lower end of motor does not increase any safeguard procedures, then just holding very much
It is easily collided with the stone of protrusion either step, collision can all cause motor to connect loosening or motor bottom with rear chain stay every time
Deformation, if things go on like this motor will damage.
