Abstract
The utility model relates to a simple gear direct transmission type rear axle, belongs to the technical field of communication media and particularly relates to a gear direct transmission type rear axle assembly of an electro-tricycle. The simple gear direct transmission type rear axle comprises a straight axle tube of a chain rear axle, an arc axle tube of the chain rear axle, a motor of the chain rear axle, a gear set and a dust cover, wherein the gear set is composed of a big gear and a pinion, the big gear is fixed in the middle of a transmission shaft in the straight axle tube, two ends of the transmission shaft are provided with hubs, the pinion is installed on a motor shaft, the dust cover is located on the inner side of the arc axle tube, and the dust cover, the straight axle tube and a motor casing are fixed into a whole. The simple gear direct transmission type rear axle has the advantages that the simple gear direct transmission type rear axle is modified on the basis of the electro-tricycle chain rear axle which has the largest market share, so that the simple gear direct transmission type rear axle has the advantages of the chain rear axle and a gear rear axle and is free of the disadvantages of the chain rear axle and the gear rear axle, and the simple gear direct transmission type rear axle is simple in structure, high in transmission efficiency, good in dust prevention, long in service life, low in manufacturing cost and obvious in comprehensive benefits.
Description
Technical field
The utility model belongs to technical field of transportation means, particularly a kind of electro-tricycle gear direct driven type back axle assembly.
Background technology
At present; The conventional electric-powered three-wheel vehicle adopts chain and chain sprocket drive usually; Driving device is exposed in the environment that stirs up a cloud of dust fully, very easily causes the loosening and excessive clearance of corrosion, wound foreign matter, chain to cause faults such as wearing and tearing, so that shorten the service life of driving device.Electro-tricycle gear transmission back axle to the exploitation of above defective has usefulness preferably, has increased manufacturing cost but compare with chain-type transmission back axle.For this reason, it is very necessary designing a kind of novel back axle in conjunction with the advantage of two kinds of electric tricycle rearmost axles.
Summary of the invention
The purpose of the utility model is a mounting teeth wheel apparatus on conventional chains formula back axle, makes it to become a kind of low cost, dynamical gear direct driven type back axle.
The technical scheme of the utility model is: this device is made up of straight bridge tube, arc bridge tube, motor and gear cluster, the dust boot of chain-type back axle; Wherein gear cluster is made up of big gear wheel and miniature gears; Big gear wheel is fixed on the transmission shaft middle part in the straight bridge tube; The two ends of transmission shaft are equipped with wheel hub, and miniature gears is installed on the motor shaft, and dust boot is positioned at arc bridge tube inboard and is fixed as one with straight bridge tube, motor casing.
The beneficial effect of the utility model: because this device is reequiped on the electro-tricycle chain-type back axle basis of market occupancy volume maximum; Possessed the advantage of chain-type back axle and gear type back axle simultaneously, simple in structure, driving efficiency is high; Good dustproof effect; Long service life, cost of manufacture is low, and comprehensive benefit is obvious.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
This device adds that by straight bridge tube 1, arc bridge tube 2, the motor 6 of conventional chains formula back axle supporting gear cluster, dust boot 8 form; Be equipped with transmission shaft in the straight bridge tube 1; Wheel hub 3 and wheel are installed in the transmission shaft two ends; Big gear wheel 4 in the fixed teeth wheels of transmission shaft middle part, big gear wheel 4 constitutes differential gear set with miniature gears 5.The bearing 7 of motor 6 is welded on the straight bridge tube 1, and 6 in motor is gone up miniature gears 5 is installed.Dust boot 8 is formed by the sheet metal compacting, and its cost of manufacture is significantly less than the gear housing of casting structure, after the installation big gear wheel 4 and miniature gears 5 is placed in the closed space.Dust boot 8 is fixed on straight bridge tube 1 and motor 6 housings, plays dustproof and prevents that foreign matter from twisting the effect into gear cluster.
Because this device is reequiped on the electro-tricycle chain-type back axle architecture basics of market occupancy volume maximum; Possessed advantage that the chain-type back axle is big in batches, cost is low and gear type back axle driving efficiency height, long advantage of life-span simultaneously; Avoided the former the fragile and higher shortcoming of latter's cost again; Simple in structure, repacking is produced very convenient, and comprehensive benefit is obvious.
