Abstract
The invention relates to a gearbox body for an electric motor car, which comprises a back box body, a middle box body and a front box body, wherein the conjugation site of the back box body and the middle box body is provided with a first gland bush, and the conjugation site of the middle box body and the front box body is provided with a second gland bush. The gearbox body for the electric motor car is characterized in that a motor shell and the middle box body are integrated into a whole; a center on a box wall where the right part of the middle box body is connected with the front end of the motor shell is provided with a motor rotating shaft stretching hole, and the back end of the motor shell is provided with an end cover; and the upper part on the left of the middle box body is provided with a stepping motor rotating shaft stretching hole. The gearbox box body for the electric motor car has the advantages that because the box body adopts the combined structure of three parts, a transmission component and a speed change component are convenient to assemble to ensure that a speed change mechanism inside reliably transfers torque; and because the motor shell and the box body are integrated into a whole, the gearbox body has compact structure and strong integraty, and effectively improves the radiating condition of a motor.
Description
Technical field
The present invention relates to automotive component, be specifically related to a kind of gearbox body of electric motor cycle.
Background technology
In order to overcome hub-type electric motorcycle directly by the shortcoming of motor-driven trailing wheel, people have developed the power drive that is applicable to battery-operated motor cycle, are called " power gearing of electric motorcycle " as the disclosed name of CN 1613715A.This device comprises variable transmission mechanism and the connected electrical motor that is installed in the casing, substitute the oil-burning machine work done with electrical motor, simplify the structure, satisfied the needs of user electric motorcycle vehicle speed increase and hill climbing ability, but structure is not compact, and casing structure exists not enough.And for example the name of CN2889884Y bulletin is called " battery-driven car change speed gear box ", comprises that a gearbox body, one are contained in the case lid of gearbox body, one and are contained in the electrical motor on the gearbox body and are installed in dynamic retarding driving device in the change speed gear box.This device provides the effective power type of drive that outputs to driving wheel of vehicle from motor power, but the employing electrical motor is superimposed upon the mode on the gearbox body, can not improve the radiating condition of electrical motor effectively, the structure that is applicable to chain gear or bel-drivenn gearbox body is still not compact, and change speed gear box adopts casing, two structures of case lid to be not easy to the installation of drive disk assembly.
Summary of the invention
The purpose of this invention is to provide a kind of gearbox body of electric motor cycle, its compact conformation, globality are strong, are convenient to install drive disk assembly, can guarantee that the in-to-in speed-changing mechanism passes transfer torque reliably, and can effectively improve the radiating condition of electrical motor.
A kind of gearbox body of electric motor cycle of the present invention comprises rear box, middle casing and preceding casing, is provided with first packing seal at the binding site of rear box and middle casing, is provided with second packing seal at the binding site of middle casing and preceding casing, it is characterized in that:
One motor casing and middle casing are an integral body, be provided with a motor rotary shaft at motor casing front end and middle casing right part bonded assembly tank wall center and stretch into the hole, be provided with end cap in the motor casing rear end, above middle casing left part, be provided with a stepping motor rotating shaft and stretch into the hole.Adopting motor casing and middle casing is holistic structure, makes electrical motor can utilize bigger gear box of volume and interior lubricating oil heat radiation thereof, thereby has improved the radiating condition of electrical motor effectively.
Described a kind of gearbox body of electric motor cycle, be provided with main driving axle mounting hole, driven shaft bearing seat and the variable speed drum mounting hole of center of circle distribution triangular in shape on the dividing plate in described in the casing left part, be provided with in the inboard of described rear box with the cooresponding main driving shaft bearing seat of main driving axle mounting hole, with the cooresponding driven shaft mounting hole of driven shaft bearing seat and with the cooresponding variable speed drum bearing seat of variable speed drum mounting hole.This unitized construction is convenient to the installation of drive disk assembly and speed change parts,
Described a kind of gearbox body of electric motor cycle, the left side of casing is provided with oil hole in described, and the right side is provided with adapter plate; Be provided with the installation suspension ring above rear box, the below is provided with decides hole, drg flexible axle position.
The present invention compares with prior art and has the following advantages: because casing adopts three part unitized constructions, so, be convenient to the installation of drive disk assembly and speed change parts, thereby guaranteed that the in-to-in speed-changing mechanism passes transfer torque reliably; Because motor casing and casing are one,, and improved the radiating condition of electrical motor effectively so not only compact conformation, globality are strong.
