Abstract

A driving mechanism with single motor and two wheels in one side for 100% low-floor light railway vehicle independent wheel is characterized in that: two ends of the motor are respectively connected to a gear transmission mechanism to form two driving units, two driving units are symmetrically arranged on two sides of a bogie taking the vertical center as the symmetrical center, two gear transmission mechanisms are respectively connected to a front wheel and a rear wheel in the same side of the bogie, thus all the wheels can maintain the same moving direction when two output shafts on the two ends of the motor output at the same time. Two gear transmission mechanisms are respectively connected to a front wheel and a rear wheel in the same side of the bogie, and thus the synchronous operation of four wheels and safety guiding problem of independent wheel bogie structure is achieved. Two ends of the motor are connected to a gear transmission mechanism to form two driving units, thus two sets of gear boxes are driven by one motor, and the work efficiency is improved. Furthermore, the two driving unit are symmetrically arranged on two sides of the bogie taking the vertical center as the symmetrical center, and convenience is provided to maintenance and operation.

Description

100% low-floor light rail vehicle mechanism of independent wheel is to single motor homonymy two-wheel drive mechanism
Technical field
The present invention relates to a kind of use at 100% low-floor light rail vehicle mechanism of independent wheel to the single motor homonymy two-wheel drive mechanism on power truck.
Background technology
Do not exist between the right left and right wheels of independent wheel wheel to be rigidly connected, can freely rotate around axletree separately.How the right power truck of this mechanism of independent wheel arranges actuating device, is the problem of the continuous exploration of structure design engineer and primary study always.For how realizing left and right sides wheel driven in synchronism safe operation, the solution of a lot of concept formulas has been proposed, namely bogie truck with motor Single-end output structure, because of complex structure, all brings very large inconvenience to dismounting and utilization maintenance in practice.In this case, needing that development is a kind of badly can easy disassembly, can realize again the new structure that safety drives.
Summary of the invention
The purpose of this invention is to provide a kind of 100% low-floor light rail vehicle mechanism of independent wheel to the single motor homonymy two-wheel drive structure on power truck, with easy disassembly and maintenance.
For achieving the above object, the invention provides a kind of 100% low-floor light rail vehicle mechanism of independent wheel to single motor homonymy two-wheel drive mechanism, it is characterized in that: motor two ends respectively connect a gear drive and consist of driver element, two driver elements are arranged symmetrically in bogie truck both sides with longitudinal center, two gear drives are connected with former and later two independent wheels of bogie truck the same side respectively, when realizing the output shaft rotating in same direction output of motor two ends, the working direction that all wheels still can be consistent.
Driver element is to be in the same place by the flange rigid attachment by the gear drive casing of motor and its both sides, inside is assembled together with two gear drive casing side half-couplinves respectively by the motor side half-coupling, gear drive casing side semiaxis connects with pinion drive by the finishing bevel gear cuter of two right-angle drives separately, be used for and convert to along the rotation of the longitudinal axis along the rotation of transverse axis, miniature gears and gear mechanism engagement, gear mechanism is by two elastic coupling driving coupling wheels.
Two gear drives of the present invention are connected with former and later two independent wheels of bogie truck the same side respectively, have realized the four-wheel synchronized operation of independent wheel bogie structure, safe guiding problem; The motor two ends respectively connect a gear drive and consist of driver element, realize single motor-driven two sleeve gear casees, increase work efficiency; Two driver elements are arranged symmetrically in bogie truck both sides with longitudinal center and safeguard and provide convenience using.
