Abstract
A rear axle of an electric tricycle with differential gears belongs to the technical field of vehicles and particularly relates to a rear axle assembly of an electric tricycle with differential gears, which consists of axle tubes, a gearbox, a motor, a motor bracket and a transmission shaft. A casing of the gearbox is formed by a left box and a right box mutually fastened in a sealed mode, the left box and the right box are fixedly welded with the left axle tube and the right axle tube to a whole respectively, the motor bracket is fixed on the right axle tube, the motor is mounted on the motor bracket, a motor shaft is fixedly connected with a small gear, the small gear is meshed with a large gear in the gearbox to form a differential gear set, the large gear is mounted on the transmission shaft, the transmission shaft perorates into the left axle tube and the right axle tube, and two ends of the transmission shaft are fixed on a driving wheel axle. The rear axle has the advantages of simple structure, reliability in operation, convenience in maintenance and lower manufacture cost. Compared with chain transmission, the gearbox is excellent in sealing and lubricating effects and higher in transmission efficiency, thereby reliability of the rear axle is greatly improved and the service life of the rear axle is greatly prolonged.
Description
Technical field
The utility model belongs to technical field of transportation means, particularly a kind of electro-tricycle gear differential speed rear axle assembly of sand.
Background technology
At present, traditional electro-tricycle adopts chain and chain sprocket drive usually, and driving device is exposed in the environment that stirs up a cloud of dust fully, very easily causes faults such as corrosion, wound foreign matter.Simultaneously, elongation easily in chain and the sprocket wheel high-speed operation must often be adjusted, otherwise because chain is loosening and the excessive clearance enhance faster wear, so that shorten the service life of driving device.
Summary of the invention
The purpose of this utility model is lower, the reliable electro-tricycle gear transmission back axle of a kind of cost of design, to overcome the defective of chain gear.
The technical solution of the utility model is: this device is by bridge tube, gear case, motor and electric machine support, transmission shaft is formed, wherein gear box casing is fastened mutually by left box body and right case and is sealed to form, left box body left side and the left bridge tube structure that is fixed as one, right case right side and the right bridge tube structure that is fixed as one, also be fixed with electric machine support on the right bridge tube, motor is installed on the electric machine support, motor shaft is captiveed joint with miniature gears, miniature gears and big gear wheel mesh in gear case forms differential gear set, big gear wheel is installed on the transmission shaft, transmission shaft runs through in the bridge tube of the left and right sides, and its two ends are fixed on the live axle.
The beneficial effects of the utility model: because this apparatus structure is simple, gear housing airtight, lubricant effect is good, driving efficiency improves, and compares with chain gear and has improved greatly reliability and service life.Cost of manufacture is lower, and benefit is obvious.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
This device middle gear tank shell is fastened mutually by stamping forming left box body 7 of steel plate and right case 8 and is sealed to form, reinforce with holding screw then, left box body 7 left sides and 1 welding of left bridge tube are fixed as one, and right case 8 right sides and 2 welding of right bridge tube are fixed as one, and left and right sides bridge tube keeps the axle center unanimity.Be fixed with electric machine support 4 on the right bridge tube 2, motor 3 is installed on the electric machine support 4.Be added with pad between motor 3 and the electric machine support 4 to adjust the shaft core position of motor 3.Motor shaft is captiveed joint with miniature gears 5, and miniature gears 5 meshes in gear case with big gear wheel 6 forms differential gear set, and big gear wheel 5 is fixedly mounted on the transmission shaft 9, and transmission shaft 9 runs through in the left and right bridge tube, and its two ends are fixed on the electro-tricycle live axle.The fixing compartment load-bearing stage clip of electro-tricycle respectively on a left side bridge tube 1 and the right bridge tube 2.
