Abstract
The utility model relates to a transmission case of an electric vehicle, particularly a speed changing device for an electric vehicle. On the basis of a publicly known transmission case body, a bearing seat, a bearing cover, a differential mechanism assembly, a bearing and various standard components, a motor flange is arranged between a motor and the transmission case; the motor is integrally connected with the transmission case through the motor flange; an output shaft of the motor can be directly inserted into a connecting sleeve of the transmission case; dynamic force can be transmitted to a first shaft of the transmission case through the connecting sleeve; the first shaft is a gear shaft; a first shaft driving gear is arranged on the first shaft; the first shaft driving gear drives a driven gear arranged on a second shaft; the driven gear can drive the second shaft through a connecting disk; the second shaft is a gear shaft; a second shaft driving gear is arranged on the second shaft; the second shaft driving gear can drive a driven gear on a differential gear casing; the driven gear drives a differential mechanism to rotate; dynamic force can be transmitted to two wheels; thereby, the two stage transmission of dynamic force can be completed. Because the utility model is adopted, the dynamic force can be directly transmitted to the transmission case by the motor; the dynamic force can be directly transmitted to the two wheels through the transmission case; the dynamic force loss can be reduced. The utility model has the advantages of simple structure, simple manufacture, low cost, etc.
Description
Technical field
The utility model relates to a kind of battery-driven car transmission system.
Background technology
At present, known electro-tricycle power transmission is to pass to sprocket wheel on the tricycle rear axle by motor by chain, and the transmission shaft that sprocket wheel drives in the back axle is passed to two wheels, finishes the transmission of power.Power is passed to by chain in the process of sprocket wheel, because the inherent defect of chain, power is easy to generate loss, causes power transmission efficiency not high, and is easy to generate noise.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel electric vehicle change speed gear box, and power is directly passed to change speed gear box by motor, and change speed gear box is directly passed to two wheels by transmission shaft.
The technical scheme that its technical matters that solves the utility model adopts is: at known gearbox body, bearing seat, bearing cap shim, differential assembly, on the basis of bearing and various gauge members, between motor and change speed gear box, motor flange is set, motor is connected as a single entity by motor flange and change speed gear box, motor output shaft directly inserts the adapter sleeve in the change speed gear box, power is passed to change speed gear box by adapter sleeve one, the output shaft of motor is connected by spline by adapter sleeve with one, one is gear wheel shaft, be provided with a driving gear above, the ring gear of a driving gear drive installation on two, ring gear drives two by terminal pad, two is gear wheel shaft, be provided with two driving gears above, two driving gears drive the differential side-gear on the differential casing, differential side-gear drives the diff rotation, and power is passed to two wheels, finishes the two-stage transmission of power.
The beneficial effects of the utility model are that power is directly passed to change speed gear box by motor, and change speed gear box is directly passed to two wheels with power, has reduced power waste, can realize high reduction of speed ratio, and have simple in structure, be easy to make, advantage such as productive costs is low.
