Specific embodiment
In order to be more clearly understood that the above-mentioned purpose of the utility model, feature and advantage, below in conjunction with the accompanying drawings and have
The utility model is further described in detail in body embodiment.It should be noted that in the case where there is no conflict, this Shen
The feature in embodiment and embodiment please can be mutually combined.
Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality
New to be implemented using other different from other modes described here, therefore, the scope of protection of the utility model is simultaneously
From the limitation of following public specific embodiment.
As shown in Figure 1 and Figure 2, the freight electric vehicle of the utility model, including vehicle frame 1, vehicle frame is integrally hollow frame knot
The steelframe of structure, the front lower portion of vehicle frame 1 are provided with front overhang hanging hang structure（Attached drawing is not shown）, front overhang hanging hang structure include front-wheel and steering
Device, transfer are connected with being arranged on the handlebar of vehicle frame upper front end, driver by control handlebar control electric vehicle rotary to.
Post-suspension structure is arranged on 1 rear end lower of vehicle frame, after post-suspension structure includes damper 2, the first rear axle 3, second
Bridge 4 and positioner, damper 2 is the leaf spring of circular shape, if being fixed by the alloy-steel plate of the wide Length discrepancy of dry plate
Connection composition, 1 two curb girder bottoms of vehicle frame are each provided with a damper 2, and 2 arc top position of damper is connected to vehicle frame 1 two
Curb girder bottom, the both ends of damper 2 are hinged with the first rear axle 3 and the second rear axle 4 respectively.Positioner includes stabiliser bar 5 and indulges
Pull rod 6, stabiliser bar 5 traverse vehicle frame 1 and are fixed on vehicle frame 1, and stabiliser bar 5 is used for balancing vehicle body, and it is excessive to prevent that vehicle body from occurring
It laterally rolls, stabiliser bar both ends connect two longitudinal ties 6 respectively, and two 6 one end of longitudinal tie are hinged on stabiliser bar 5, the other end
Respectively with two rear-axle hingings, positioner is used for connecting and positioning two rear axles, prevents two rear axles in pressure or road conditions
De- axis or off-axis under variation.
As shown in Figure 3, Figure 4, under electric vehicle loading state, 2 stress of damper of circular shape deforms upon, and vehicle frame 1 drops
Low to be approached with rear axle, distance becomes larger between two rear axles, and the angle between the longitudinal tie 6 of positioner becomes larger therewith.Traditional electric car
In rear axle structure, 2 arc top of damper is fixed on hind axle, and both ends are connected on vehicle frame 1, when vehicle frame 1 is subject to vertical load, are subtracted
2 both ends of shake device are persistently subject to the pressure of vehicle frame 1, and 2 internal stress of damper increases, and not only shorten 2 service life of damper, and
