Abstract
The invention relates to a driving system of a battery transport car, wherein a direct current motor and a gear box are fixed together; a fixed big internal gear ring is arranged in the gear box; a sun gear is arranged on a direct current motor shaft; an output shaft is fixed on the gear box right opposite the sun gear by a bearing; a planetary gear carrier is fixed at the end of the output shaft in the gear box; two or three same planetary gears are uniformly arranged on the planetary gear carrier; the planetary gears are meshed with a fixed big internal gear and the sun gear in the meantime; a differential mechanism is arranged in the middle of a rear axle; a power input end of the differential mechanism and the output shaft are connected by utilizing a cardan joint; two sides of the real axle are respectively provided with a half axle; and driving wheels are fixed on the half-axle ends. The driving system disclosed by the invention has the advantages that a better shock-absorbing effect is provided and the service life can be prolonged.
Description
Technical field
The present invention relates to the storage battery transport trolley, be specifically related to the drive system of storage battery transport trolley, belong to storage battery transport trolley technical field.
Background technology
In the cargo transfer process of inside plants, use the storage battery transport trolley mostly, the drive system of existing storage battery transport trolley generally comprises electrical motor, gear case, diff, back axle, left and right sides semiaxis and drive wheel and forms; On version; Gear case and back axle are connected into integral body, and electrical motor and gear case install and fix together, and are the installation of parastate between the input and output shaft of motor shaft, gear case and the left and right sides semiaxis in the back axle; The drive system of the storage battery transport trolley of this version; Though have the advantage of compact conformation, because whole drive system and back axle install and fix together rigidly; Vehicle is in the process of going; The suffered vibrations of the motor of driving system and gear case are also bigger, and descended to the service life of motor and gear case, when serious even can damage corresponding parts.
Summary of the invention
The objective of the invention is to: to the existing above-mentioned scarce limit of existing storage battery car, the present invention provides a kind of drive system of novel storage battery transport trolley, overcomes the existing existing above-mentioned defective of storage battery transport trolley.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: the drive system of described storage battery transport trolley; Comprise: DC machine, sun gear, planetary gear carrier, universal-joint, back axle, diff, semiaxis, drive wheel, output shaft; It is characterized in that: described DC machine and gear case install and fix together; In gear case, install and fix the big internal gear circle, the interior tooth top circle and the DC machine axis of described fixedly big internal gear circle coincide, and on the direct current (DC) arbor, sun gear are installed; Output shaft is installed in above the gear housing of sun gear right opposite with bearing fixing; Output shaft end in gear case installs and fixes planetary gear carrier, and circumferencial direction is equipped with two or three identical planetary wheels evenly in the planetary gear carrier upper edge, and described planetary wheel is simultaneously with fixedly big internal gear and sun gear form intermeshing relation; Centre at back axle is equipped with diff; Link to each other with universal-joint between the power intake of described diff and the output shaft, a semiaxis is installed in the both sides of back axle, described semiaxis end is mounted with drive wheel.
Beneficial effect: the present invention can prolong the service life of driving system owing to after adopting said method, have shock-proof effect preferably.
Description of drawings
Accompanying drawing 1 is a structure principle chart of the present invention;
