Abstract
The utility model relates to an integral suspending hinged electric conjoined rear bridge assembly, comprising a conjoined differential speed bridge which is composed of a pair of half shafts, half shaft tubes and a differential speed box. A suspension is fixedly connected with the half shaft tubes; the output shaft of a motor is directly connected with the input shaft of the differential speed box; and a hinge mechanism which can be movably connected with the front vehicle frame is arranged at the front end of the suspension. The rear bridge assembly has compact structure; and the motor is close to the differential speed box so no long shaft transmission is needed. The suspension can be conveniently hinged with the front vehicle frame; the installation of the whole vehicle is simple. Thus, the utility model is applicable for electric small-sized delivery vehicles or tricycles.
Description
(one) technical field
The utility model relates to the hinged electronic conjuncted back axle assembly of a kind of integral hanging, belongs to the elec. vehicle field.
(two) background technology
At present, the driving engine of power actuated vehicle or electrical motor and change speed gear box are arranged on the front portion of vehicle frame more, and the distance between the diff is big, need by the major axis transmission.Because the technical requirements height of shaft transmission is too high, not too suitable for home vehicle manufacturing costs such as small farm car or motor-tricycles.
(three) summary of the invention
The purpose of this utility model provides the hinged electronic conjuncted back axle assembly of integral hanging that a kind of suitable small-sized electric vehicle uses, and it makes motor, diff and back axle be combined into back axle compactly and hangs assembly, and designs simplification reduces the vehicle manufacturing cost.
The back axle that the hinged electronic back axle assembly of this integral hanging comprises suspension and is made up of a pair of semiaxis and semiaxle tube, differential box and back axle join together forms conjuncted differential bridge, captive joint with semiaxle tube in the rear end of suspension, the output shaft of motor directly links to each other with the input shaft of differential box, the front end of suspension is equipped with the linkwork that can articulate with the activity of front end vehicle frame, this linkwork comprise a removable pin and a pair of can with front end vehicle frame pivotally attached hangers.In addition, motor also can be fixed on the suspension, and its output shaft links to each other with differential box by pulley transmission mechanism.
This back axle assembly also is welded with a pair of shockproof mount on the two halves central siphon, be used to the spring damper of packing into.The rear side of this assembly is provided with the stabilizer rod of equality in back axle, and an end of stabilizer rod is fixed on the semiaxle tube by linkwork, to strengthen the balance quality of this assembly in vehicle '.
In the hinged electronic conjuncted back axle assembly of the utility model integral hanging, adopted conjuncted differential bridge construction, motor is positioned at suspension, and adjacent change-speed box need not the major axis transmission, and simple in structure, cost is low.Each parts is compact to be settled, also very convenient with the connection of front end vehicle frame, is suitable for small transporting vehicle or motor-tricycle.In addition, the removable pin of suspension front end and hinged hangers make vehicle can adapt to travelling of uneven road surface and uphill/downhill, avoid overturning, and the stabilizer rod of rear side more can be strengthened the riding stability of vehicle.
(four) description of drawings
Further specify the structure of the hinged electronic conjuncted back axle assembly of integral hanging below by accompanying drawing.
Fig. 1 is the structural representation that the hinged electronic conjuncted back axle assembly of this integral hanging of trailing wheel is housed.
Fig. 2 represents to adopt the mounting means scheme drawing of motor in this back axle assembly of pulley drive.
(five) specific embodiment
As shown in Figure 1, bag differential box 63 is formed the conjuncted differential bridge 6 that is connected as a single entity with a pair of semiaxis 62 and semiaxle tube 61, wherein, semiaxis 62 is connected (diff is in the case of differential box 63) with diff, semiaxle tube 61 links to each other with the casing of differential box, the rear end of rear suspension 4 and semiaxle tube 61 welding are fixed into one, and the cylindrical shape shockproof mount 5 that is used for the mounting shock absorber spring also is weldingly fixed on semiaxle tube 61; Buncher 3 adjacent differential boxs 63, the output shaft of motor directly insert in the casing of differential box and are connected with diff.Represent also among the figure that the suspension front end is provided with removable pin 2, can relatively rotate between it and the suspension 4, back axle is swung flexibly, the front end of removable pin connects a pair of hinged hangers 1, they can be hinged with the vehicle front vehicle frame, and back axle can be swung up and down around the vehicle frame of front end, and the left end of stabilizer rod 7 is provided with linkwork 7-1, its right-hand member can be swung around jointed shaft, improves the stability of back axle.Represent also among the above-mentioned figure that the semiaxis two ends are connected with drg 8 and trailing wheel 9.Fig. 2 represents motor 3 by being bolted on the suspension 4, and its output shaft links to each other with the differential box input shaft by belt pulley 10.
