Abstract
The utility model relates to an electric vehicle dual-drive device, comprising an electric vehicle rear axle and a main motor arranged on a motor mounting plate. A driving chain wheel is arranged on the motor shaft; a transmission chain wheel is arranged on the rear axle; the driving chain wheel and the transmission chain wheel are connected with each other through a chain; an assistant motor is arranged on the lengthened motor mounting plate parallel to the main motor; an unidirectional chain wheel is arranged on the assistant motor shaft; a synchronous chain wheel, which outer diameter and tooth number are equal to the unidirectional chain wheel is arranged at one side of the main motor shaft driving chain wheel; the unidirectional and synchronous chain wheels are connected with each other through an assistant chain to form an integral structure of double chain wheels. As for the utility model, the assistant motor and the unidirectional chain wheel are added on the original motor driving basis and two motors can be used simultaneously for climbing or alternately used for increasing the maximum traveling.
Description
Technical field:
The utility model belongs to general vehicle, particularly a kind of battery-driven car double driving mechanism that makes electro-tricycle or four-wheeled strengthen ability of climbing brokenly and travelled distance.
Background technology:
At present, the driver train of electric three-wheel or four-wheeled all is to fix a motor mounting plate on back axle, fixes an electrical motor on the motor mounting plate, fix a sprocket wheel on the wheel shaft in back axle, on back axle sprocket wheel and motor shaft sprocket wheel, be connected a chain jointly.Motor-driven three-wheel of this separate unit or four-wheel electric motor car, the shortcoming of existence are that load-carrying climbing is little because of propulsive effort when travelling, and the climbing gradient is restricted, the gradient that empty wagons can get on and loaded vehicle does not increase; Be that range is short in addition, be not suitable for long-distance running.
Summary of the invention:
It is strong that the purpose of this utility model provides a kind of load-carrying hill climbing ability that travels, the battery-driven car double driving mechanism that range is far away.
The technical solution of the utility model is finished as follows, it includes the main motor on battery-driven car back axle and its motor mounting plate, drive sprocket is installed on motor shaft, driving chain wheel is installed on hind axle, between drive sprocket and driving chain wheel, be connected with a chain, it is characterized in that: parallel with main motor on the motor mounting plate of lengthening a helper motor is installed, an One-way chain wheel is installed on the auxiliary electrical arbor, a side of drive sprocket is equipped with a synchronous sprocket wheel that equates with warp and the number of teeth outside the One-way chain wheel on main motor shaft, is connected with an auxiliary chain between synchronous sprocket wheel and One-way chain wheel.Above-mentioned synchronous sprocket wheel and drive sprocket are the two strands wheels of an one.
The utility model is used for climbing brokenly owing to increasing a helper motor and One-way chain wheel thereof again on existing motor-driven basis, can driving simultaneously as required, drives in turn and is used for increasing range.
Description of drawings:
Accompanying drawing is a structural scheme of mechanism of the present utility model.
The specific embodiment:
The utility model is on the basis of existing technology, keep driving chain wheel 2, chain 13, the brake wheel 3 on back axle 1, the hind axle, the dish 4 of stopping constant, just with 5 lengthenings of the motor mounting plate on the back axle, parallel main motor 6 usefulness bolt of rear end plates 8 install and fix a helper motor 7 on the motor mounting plate of lengthening, an One-way chain wheel 9 is installed on the auxiliary electrical arbor, the core wheel of One-way chain wheel is fixed on the auxiliary electrical arbor, and be connected by the click unidirectional rotation between its cylindrical and the core wheel, One-way chain wheel can only be rotated by the direction of arrow in the accompanying drawing.On main motor shaft, be fixed with the external diameter synchronous sprocket wheel 11 identical with it, be connected with auxiliary chain 10 between synchronous sprocket wheel and the One-way chain wheel with the number of teeth corresponding to One-way chain wheel.Produce for convenience and install, also the drive sprocket 12 on synchronous sprocket wheel and the main motor can be linked together, become the two strands wheel of an one.When load-carrying is climbed, in time open helper motor, helper motor rotates through the driving chain wheel drive wheels that chain drives on the hind axle through the drive sprocket that auxiliary chain drives on synchronous sprocket wheel and the main motor simultaneously by One-way chain wheel, strengthen hill climbing ability, when changing flat pavement running over to, can close helper motor, helper motor is stopped operating, and One-way chain wheel is only along with the synchronous sprocket wheel rotation of skidding.When main motor power shortage, can close main motor, drive synchronous sprocket wheel by helper motor through auxiliary chain, make the sprocket wheel on the hind axle continue to drive battery-driven car, increase mileage.
Claims (2)
1, a kind of battery-driven car double driving mechanism, it includes the main motor on battery-driven car back axle and its motor mounting plate, drive sprocket is installed on motor shaft, driving chain wheel is installed on hind axle, between drive sprocket and driving chain wheel, be connected with a chain, it is characterized in that: parallel with main motor on the motor mounting plate of lengthening a helper motor is installed, an One-way chain wheel is installed on the auxiliary electrical arbor, a side of drive sprocket is equipped with a synchronous sprocket wheel that equates with warp and the number of teeth outside the One-way chain wheel on main motor shaft, is connected with an auxiliary chain between synchronous sprocket wheel and One-way chain wheel.
2, a kind of battery-driven car double driving mechanism according to claim 1 is characterized in that: above-mentioned synchronous sprocket wheel and drive sprocket are the two strands wheels of an one.
