Abstract
An electric tricycle axle driving device is provided, comprising a direct current motor (1), a differential gear (7), a plurality of wheels (9) and a wheel axle (8). The utility model is characterized in that the output axle of the direct current motor is a splined shaft, the splined shaft is meshed with the inner spline of a universal joint seat (2), the other end of the universal joint seat (2) is connected with at least one universal joint seat through a cross joint, the tail part of the universal joint (5) on the end part is an inner spline, the inner spline is meshed with the spline on a differential gear input axle (6), a bevel gear on the differential gear input axle (6) is meshed with the bevel gear of the differential gear. The utility model adopts the universal joint and the cross joint combination to transfer the force from the motor to the differential gear, greatly decreases the driving tache, improves the mechanical strength of the driving parts, improves the security, reliability and service life of the driving components, decreases the fault rate, and greatly improves the security, reliability and service life of the electric tricycle.
Description
Technical field
The utility model relates to a kind of transmission device of electro-tricycle, particularly a kind of electro-tricycle shaft transmission.
Background technology
Electro-tricycle is mainly used in short range delivery article, is specially adapted to peasant household's delivery material used for agriculture and far products, also is suitable for little trade company and carries cargo, and compares with trishaw to have characteristics such as speed is fast, carrying is big, easy to use.Electro-tricycle is to grow up on the basis at trishaw, and its transmission device prolongs the chain drive of having attacked trishaw, and develops into the double strand chain transmission by the strand transmission.The transmission link of chain-driving own is many, and these transmission devices are exposed at the car body bottom outward, silt, dusts a large amount of during use are invaded, and cause big minor sprocket and chain wear serious, cause each binding site of chain lax, transmitting movement is unreliable, shake is arranged during starting, and dry sound is big, and part damages easily, transmission device fault rate height, maintenance is inconvenient.
Summary of the invention
The purpose of this utility model is that it is few to propose a kind of transmission link, durable in use, the transmission device of safe and reliable electro-tricycle.
Structure of the present utility model is, the electro-tricycle shaft transmission, include DC machine, diff, wheel and wheel shaft, it is characterized in that the DC machine output shaft is a castellated shaft, with the female splines engagement of universal socket, universal socket end in addition is connected with at least 1 universal socket by the cross joint, the tail end of the universal-joint of end is a female splines, is meshed with spline on the diff input shaft, and the bevel gear on the diff input shaft is meshed with the diff bevel gear.
The utility model is to connect universal socket by the cross joint, and an end of universal socket links to each other with motor output shaft by spline, and the end in addition of universal socket is connected with the diff input shaft by spline realizes shaft drive.Cross joint is the attaching parts that constitutes of 4 sections axles of 90 degree each other at grade, is generally the attaching parts of standard universal.Universal socket is general part in addition, and two ends are provided with the axis hole of 90 degree each other, and there is recessed groove the end, and the axle head of cross joint inserts groove and is connected with its axis hole.The utility model is made as Len req according to the difference of vehicle with universal socket.Also can be with universal socket system shorter, and increase the quantity of universal-joint.The diff of electro-tricycle is not done change, and just the output axle head with input shaft end and motor is made as castellated shaft, and this improvement can not change to technical parameters such as the transmitting ratio of electro-tricycle itself, speed.The utility model adopts universal socket and the combination of cross joint that power is caused diff by the motor transmission, significantly reduced transmission link, improved biography intensity, safety, reliability and the service life of transmission parts have been improved, reduce fault rate, improved safety, reliability and the service life of electro-tricycle greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
DC machine (1) output axle head is made as castellated shaft, universal socket (2) left end is made as the female splines that is meshed with motor output shaft, universal socket (2) end in addition is connected with universal socket (4) by cross joint (3), universal socket (4) is connected with universal-joint (5) by the cross joint, 4 sections axle external diameters of cross joint are 20 millimeters, the tail end of universal-joint (5) is made as female splines, diff input shaft (6) end is made as castellated shaft, the female splines of the tail end of universal-joint (5) is meshed with the castellated shaft of diff input shaft (6) end, bevel gear on the diff input shaft (6) is meshed with the diff bevel gear, and the motion of diff (7) is passed to wheel (9) by wheel shaft (8).
Claims (2)
1, electro-tricycle shaft transmission, include DC machine (1), diff (7), wheel (9) and wheel shaft (8), it is characterized in that, DC machine (1) output shaft is a castellated shaft, female splines engagement with universal socket (2), universal socket (2) end in addition is connected with at least 1 universal socket by cross joint (3), the tail end of the universal-joint of end (5) is a female splines, be meshed with the spline on the diff input shaft (6), the bevel gear on the diff input shaft (6) is meshed with the diff bevel gear.
2, electro-tricycle shaft transmission as claimed in claim 1 is characterized in that, transmission device is connected with 2 cover cross joints by 3 universal sockets.
