Abstract
The invention discloses an improvement for a transmission structure of a motor and a gear case of a horizontal second-run balance car, comprising the motor and the gear case. An output shaft of the motor is connected with an input shaft of the gear case by a transmission mechanism which comprises a clamp head part arranged on the output shaft of the motor, and a clamp sleeve part arranged on the input shaft of the gear case, the clamp head part and the clamp sleeve part are connected by a flexible structure in a clamping way, a positioning slot is arranged at the center of the clamp head part, a positioning column, corresponding to the positioning slot, is arranged at the center of the clamp sleeve part, and the positioning slot is in clearance fit with the positioning column to be connected with each other in a clamping way. By adopting the technical scheme, due to the buffering function of the flexible structure, the rigid impact and the loss on the motor and the gear case can be reduced, and the maintenance and the interconvertibility are good; and when the flexible structure is damaged, the emergency transmission can be realized by the matching of the positioning slot and the positioning column, so that a car can be prevented from failing to run when coming to an anchor.

Summary of the invention
Technical problem to be solved by this invention just provides a kind of horizontal two drive mechanisms of taking turns balance car motor and gear-box and improves, have simple in structurely, transmission is reliable and stable, and is little to motor and gear-box loss, advantage easy to maintenance, as can't to move after can avoiding casting anchor.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: horizontal two drive mechanisms of taking turns balance car motor and gear-box improve, comprise motor, gear-box, the output shaft of motor is connected with the input shaft of gear-box by driving mechanism, it is characterized in that: described driving mechanism comprises the dop portion on the output shaft that is located at motor and is located at cutting ferrule portion on the gearbox input shaft, described dop portion and cutting ferrule portion are by the flexible structure clamping, described dop portion center is provided with locating slot, described cutting ferrule portion center is provided with the locating column corresponding with described locating slot, described locating slot and the clamping of locating column Spielpassung.Adopt technique scheme, behind the electric motor starting, locating slot cooperates with locating column, and dop portion cooperates with cutting ferrule portion, makes drive mechanism more firm.By the buffer function of flexible structure, can reduce rigid impulse to motor and gear-box, reduce loss to motor and gear-box, simultaneously can prevent to skid, and in the driving mechanism during a certain parts damages, only needing the corresponding parts that damage of changing to get final product, maintenance interchangeability is good.And when flexible structure is damaged, can realize emergent transmission, can't move after avoiding casting anchor by locating slot and cooperating of locating column.
Preferably, described directional post is six prism structures, and corresponding described pilot hole is six prismatic holes.
Improved, be provided with circular transition chamfering between the directional post two side walls of described six rib structures.Reduce the infringement that the corner angle collision causes.
Preferably, described flexible structure is included as drive sleeve in the middle of the plastics that are located between dop portion and the cutting ferrule portion, dop portion and cutting ferrule portion respectively with the drive sleeve clamping of described centre.
Preferably, described dop portion is a rigidity metal card head, and described cutting ferrule portion is for being rigidity metal ferrule portion.This design makes dop portion and cutting ferrule portion serviceability good, and product only needs the middle drive sleeve of some easy losses of polygamy to get final product, and reduces maintenance cost.
Preferably, described in the middle of drive sleeve inner ring surface and outer ring surface be provided with draw-in groove, the outer ring surface of described dop portion and the inner ring surface of cutting ferrule portion are provided with corresponding card muscle.
Preferably, described dop portion is the plastic card head, and described cutting ferrule portion is a plastics cutting ferrule portion, and described dop portion moving card is contained in the described cutting ferrule portion, is realized flexibly connecting by dop portion and cutting ferrule portion itself.
Preferably, the outer ring surface of described dop portion is provided with card muscle one, and the inner ring surface of described cutting ferrule portion is provided with corresponding draw-in groove one.
The drive mechanism that the present invention horizontal two takes turns balance car motor and gear-box improves simple in structure, transmission is reliable and stable, little to motor and gear-box loss, easy to maintenance, just in case when flexible structure is damaged, can realize emergent transmission by locating slot and cooperating of locating column, make vehicle operating, avoid vehicle to cast anchor on the way to maintenace point.
