Abstract
The utility model discloses a driving system for an electric tricycle, which belongs to the technical field of electric tricycles and aims to overcome defects of high possibility of burning a motor out and short service life of the motor and other defects existing in the driving system of the conventional electric tricycle. According to a technical scheme, a driven chain wheel or gear is fixedly connected with a planet gear carrier of a differential device; a left driving semi-shaft and a right driving semi-shaft are fixedly arranged at output ends of the left and right sides of the differential device respectively; two wheels are fixedly arranged on the end parts of the left driving semi-shaft and the right driving semi-shaft respectively; an overrunning clutch is fixedly arranged on an output shaft of a gearbox; a driving chain wheel or gear is fixedly arranged on the outer circle of a driven part of the overrunning clutch; a transmission relation is formed between the driving chain wheel or gear and the driven chain wheel or gear; and the motor is connected with an input end of the gearbox.
Description
Technical field
The utility model relates to a kind of electric three-wheel motor vehicle drive system, belongs to electric three-wheel motor vehicle drive system technical field.
Background technology
Electro-tricycle has flexible, and characteristics easy to use are used in small towns, the rural area of China widely.In the drive system of prior electric three-wheel vehicle, although drive system is not quite similar on concrete structure; Transmitting ratio between from the motor to the wheel generally is changeless; Electro-tricycle with this kind drive system, the speed of vehicle rely on control motor speed speed degree to realize fully, so; Vehicle is under climbing or heavily stressed situation; The load of motor is increased the weight of, not only burn motor easily, reduce the service life of motor, even make the vehicle can't cruising.
Though the part electro-tricycle is also arranged at present, the change speed gear box that can change transmitting ratio is set in drive system, it is the existing defective of fixed form drive system that this drive system has overcome transmitting ratio to a certain extent; Because this kind drive system generally is between motor and gear case, power-transfer clutch to be set, under the situation of disengaging of clutch, through steering unit, the pick off gear group in the steerage gear case; Change the transmitting ratio of drive system, reach the purpose of speed change, plant the structure and the method for work of drive system thus and can know: vehicle is in the process of going, under the drive of wheel; Pitch wheel in the gear case also will rotate unceasingly, so, in speed change in such cases; Cause gear to beat the phenomenon of tooth easily, the service life of gear is lower, even can cause the damage of gear; In addition, in the process that vehicle slides, because a part of kinetic energy of vehicle is converted into the kinetic energy of drive disk assembly such as gear case; So the vehicle with this kind drive system also exists expenditure of energy higher, is unfavorable for the industry policy of energy-conserving and environment-protective; Moreover the vehicle with this kind drive system is owing to the general complex structure of power-transfer clutch, and not only cost is higher; Also have the higher defective of fault rate, especially serious is: because the manipulation of power-transfer clutch and the manipulation of gear case speed change will be carried out separately, make operating process loaded down with trivial details; Cause maloperation easily, not only damage vehicle easily, even also can cause traffic accident and life safety misadventure.
Summary of the invention
The purpose of the utility model is: a kind of drive system of electro-tricycle is provided, overcomes the existing existing above-mentioned defective of electric three-wheel motor vehicle drive system.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is: a kind of electric three-wheel motor vehicle drive system; Comprise wheel, left jack shaft, right jack shaft, diff, by movable sprocket or gear, drive sprocket or gear, overriding clutch, gear case, motor; Described gear case is the change speed gear box more than two grades or two grades of pick off gear formula; Planetary gear carrier by movable sprocket or gear and diff is connected and fixed, and left jack shaft and right jack shaft are fixed on the mouth of the right and left of diff respectively, and two wheels are fixed on the end of left jack shaft and right jack shaft respectively; Install and fix overriding clutch on the output shaft of gear case; Install and fix drive sprocket or gear on the cylindrical of overriding clutch passive components, described drive sprocket or gear and can be gear simultaneously or be sprocket wheel simultaneously by movable sprocket or gear be when being sprocket wheel when drive sprocket or gear and by movable sprocket or gear simultaneously; Then both link to each other through chain; When being gear simultaneously when drive sprocket or gear and by movable sprocket or gear, then both link to each other with the mode that gear is meshed, and motor links to each other with the input end of gear case.
Beneficial effect: the utility model is owing to adopt the change speed gear box more than two grades or two grades of pick off gear formula; So, can realize the purpose of vehicle mechanical formula speed change, it is existing to overcome simple dependence electric machine speed regulation speed change; Vehicle is under climbing or heavily stressed situation; The load of motor is increased the weight of, burn motor easily, reduce the service life of motor, even make the defective that vehicle can't cruising.Simultaneously, owing on the output shaft of gear case, install and fix overriding clutch, on the cylindrical of the passive components of overriding clutch, install and fix drive sprocket or gear; Operator's hand leaves the electric machine speed regulation handle, just can the direct control steering unit, directly to the gear case speed change; Handle simply, can overcome the three-wheel vehicle of existing gear case speed change effectively, because the manipulation of power-transfer clutch and the manipulation of gear case speed change will be carried out separately; Make operating process loaded down with trivial details; Cause maloperation easily, damage vehicle easily, also can cause the defective of traffic accident and life safety misadventure! Simultaneously, because the driving part and the passive components of overriding clutch exist under the situation of velocity contrast and can separate automatically; So in the process that vehicle slides, the kinetic energy of vehicle can not be converted into the kinetic energy of other drive disk assembly of drive system; So, have the advantage of energy-conserving and environment-protective.
