Abstract
The utility model discloses a rear axle for electric vehicles, which is mainly composed of an electric motor, a driving half axle, a driven half axle, a speed reducer, and a shaft coupling. The speed reducing output shaft of the electric motor directly drives the driving half axle through the shaft coupling. The rear axle for electric vehicles can be installed on electric vehicles with a plurality of specifications, and corresponding suspension and vibration dampening mechanisms are easy to design. The utility model has the advantages of compact structure, low failure rate, economic cost, low power consumption, low noise, etc. and is suitable for the popularization on electric vehicles.
Description
The utility model relates to a kind of driving, driving device of power actuated vehicle, and especially a kind of elec. vehicle drives, driving device.
At present, driving, the driving device of equipment of small motor vehicle back axle adopt chain transmission mode mostly, and the prime power output shaft is passed to trailing wheel by sprocket wheel, chain with power.The elec. vehicle that grows up in order to help environmental protection has been continued to use the mode of former chain gear.In use, there is the problem that structure is numerous and diverse, fault rate is high in this transmission, and cost is also high, for the car load layout inconvenience is arranged more.
The purpose of this utility model is: at the problem that above-mentioned existing battery-driven car back axle transmission exists, propose a kind of compact conformation, back axle that fault is few.
In order to achieve the above object, battery-driven car back axle of the present utility model comprises electrical motor, retarder, active semiaxis and passive semiaxis, wherein initiatively semiaxis and passive semiaxis are positioned at same axis, comprise coupler in addition, described electrical motor, velocity-adjuster, coupler and active semiaxis and passive semiaxis are positioned at same axis, and the deceleration output shaft of electrical motor directly drives initiatively semiaxis by coupler.
This battery-driven car back axle can be installed on the elec. vehicle of plurality of specifications, is convenient to design associated suspension, damper mechanism.After the electrical power running, wheel system behind the battery-driven car back axle direct drive of the present utility model has saved the intermediate link of chain gear.Therefore, compact conformation, watt loss is little, fault rate is low.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the external structure scheme drawing of an embodiment of the utility model.
Fig. 2 is the internal mechanism principle sketch of Fig. 1 embodiment.
Battery-driven car back axle among Fig. 1 and Fig. 2 mainly is made up of electrical motor 3, active semiaxis 8, passive semiaxis 1, planetary reduction gear 5, coupler 7.Active semiaxis 8 is positioned at same axis with passive semiaxis 1, and electrical motor 3 and the coupling housing 6 of installation planetary reduction gear 5, active semiaxis 8 and the coupling housing 2 employing seam location that passive semiaxis 1 is installed are used Bolt Connection.The output shaft of electrical motor 3 directly drives initiatively semiaxis by coupler 7 after planetary reduction gear 5 slows down.The battery-driven car back axle of this embodiment is owing to adopted the totally-enclosed housing structure of seam location, therefore can guarantee to change interaxle right alignment preferably, watt loss is little when making this battery-driven car back axle work, noise is low, not disturbed by external factor, fault rate and maintenance rate greatly reduce, and are well suited for promoting on elec. vehicle.
Claims (2)
1. battery-driven car back axle, comprise electrical motor, retarder, active semiaxis and passive semiaxis, wherein initiatively semiaxis and passive semiaxis are positioned at same axis, it is characterized in that: also comprise coupler, described electrical motor, retarder, coupler and active semiaxis and passive semiaxis are positioned at same axis, and the deceleration output shaft of electrical motor directly drives initiatively semiaxis by coupler.
2. battery-driven car back axle according to claim 1, it is characterized in that: described retarder is a planetary reduction gear, described electrical motor and the coupling housing of installation planetary reduction gear, active semiaxis and the coupling housing employing seam location that passive semiaxis is installed are used Bolt Connection.
