Abstract
The utility model discloses an electric field vehicle frame comprising a vehicle frame body, wherein the vehicle frame body is sequentially provided with a vehicle frame front part (3), a vehicle frame middle part (6) and a vehicle frame rear part (9), the vehicle frame front part (3) comprises an anti-bending girder (1), the vehicle frame rear part (9) comprises a frame structure composed of a leaf spring front seat (7), a leaf spring rear seat (10) and a plurality of reinforcement beams (11), and the vehicle frame middle part (6) is formed through welding of two main beams (4), two side beams (5) and a plurality of transverse beams (12). The weight of the vehicle frame is reduced on the bases that the structure of the vehicle frame is improved and connection is reliable.
Description
Technical field
The utility model relates to a kind of electric space vehicle vehicle frame, belongs to automobile manufacturing field.
Background technology
Electric space vehicle is as a kind of quick and easy, pollution-free, noiseless and the relatively cheap popular vehicle of price, have energy-conservation, zero pollution, the large function of zero-emission three, become expensive car and the comparatively ideal substitutes and complements of crowded bus.Therefore from environmental protection and energy-conservation angle, electric space vehicle will be a new breakthrough mouth of Domestic Automotive Industry.
Electric space vehicle in the process of moving, vehicle frame is the matrix of whole vehicle, whole net loads that it not only will carry vehicle are also carrying the live load in Vehicle Driving Cycle.Simultaneously, vehicle frame is also being born and the connecting of each assembly parts, and the various torsional deflections in driving process.
Because the power of electric space vehicle is to adopt storage battery to provide, so the total mass of vehicle is a vital index for electric space vehicle, and it directly has influence on the travelled distance of vehicle.And the quality of iron vehicle frame accounts for the 10-20% of Vehicle preparation quality, so the design of vehicle frame should in the situation that the assurance vehicle frame carry, reduce deadweight and be principle; Simultaneously, also should guarantee body frame structure for automotive rationally, connect reliable etc.
The utility model content
The technical matters that (one) will solve
The problems such as the technical problems to be solved in the utility model is to provide a kind of electric space vehicle vehicle frame, has solved the design of existing body frame structure for automotive unreasonable, conducts oneself with dignity heavier, and safety performance is not high.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of electric space vehicle vehicle frame, comprise main body of vehicle frame, described main body of vehicle frame comprises the vehicle frame that sets gradually anterior (3), vehicle frame middle part (6) and vehicle frame rear portion (9), described vehicle frame anterior (3) comprises bending resistance longeron (1), described vehicle frame rear portion (9) comprises the framed structure that is comprised of leaf spring front stall (7), leaf spring back seat (10) and some strength beams (11), and described vehicle frame middle part (6) is welded to form by two girders (4), two curb girders (5) and some crossbeams (12).
Described girder (4) is of a size of the rectangle hollow pipe of 60 * 40 * 4cm.
Described curb girder (5) is of a size of the hot rolling equal angle steel of 40 * 40 * 3cm.
Described vehicle frame anterior (3) is provided with the first connecting panel (2) with the junction at vehicle frame middle part (6), and described vehicle frame middle part (6) is provided with the second connecting panel (8) with the junction at vehicle frame rear portion (9).
(3) beneficial effect
The utility model is compared to prior art, has following beneficial effect: it reduces the vehicle frame deadweight optimizing body frame structure for automotive, connecting on the basis such as reliable.After calculating through force analysis, intensity, (the part kind is 120 * 60 * 4cm) to change 60 * 40 * 4cm into by 80 * 60 original * 4cm with two girders of original vehicle frame, in the weakest front of intensity, in after the junction, design has increased special-purpose reinforced company fishplate bar, has further improved structural strength.Therefore structure design is more reasonable, simultaneously on original basis weight reduction 10% left and right.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation two of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of electric space vehicle vehicle frame as depicted in figs. 1 and 2, comprise main body of vehicle frame, described main body of vehicle frame comprises the vehicle frame front portion 3 that sets gradually, vehicle frame middle part 6 and vehicle frame rear portion 9, described vehicle frame front portion 3 comprises bending resistance longeron 1, described vehicle frame rear portion 9 comprises the framed structure that is comprised of leaf spring front stall 7, leaf spring back seat 10 and some strength beams 11, and described vehicle frame middle part 6 is welded to form by two girders 4, two curb girders 5 and some crossbeams 12.
Described girder 4 is of a size of the rectangle hollow pipe of 60 * 40 * 4cm.Described curb girder 5 is of a size of the hot rolling equal angle steel of 40 * 40 * 3cm.Described vehicle frame anterior 3 is provided with the first connecting panel 2 with the junction at vehicle frame middle part 6, and described vehicle frame middle part 6 is provided with the second connecting panel 8 with the junction at vehicle frame rear portion 9, can effectively avoid the body frame structure for automotive Strength Failure.
This main body of vehicle frame is girder frame, and body-chassis frame construction is placed on this main body of vehicle frame, and the main body of vehicle frame strength and stiffness are large, and body distortion is little, and stationarity and safety are good, and noise is low.
The vitals such as operator's compartment and steering hardware are equipped with in vehicle frame front portion 3, in order to guarantee that unlikely turning round gone bad or because of the deformation effect driving performance, arranged two bending resistance longerons 1 that bending strength is larger at this under steam.
The framed structure at vehicle frame rear portion has guaranteed the stability of vehicle, and the design rigidity is larger.
The rigidity at the anterior and vehicle frame of vehicle frame rear portion is all larger, thereby most of vehicle frame distortion (crooked, reverse) just concentrates on vehicle frame middle part 6, this section should allow certain flexing distortion, to play buffer action, also can avoid simultaneously stress to concentrate, therefore adopt the welded structure of girder, curb girder and crossbeam.
After calculating through force analysis, intensity, (the part kind is 120 * 60 * 4cm) to change 60 * 40 * 4cm into by 80 * 60 original * 4cm with two girders of original vehicle frame, in the weakest front of intensity, in after the junction, design has increased special-purpose reinforced company fishplate bar, has further improved structural strength.Therefore structure design is more reasonable, simultaneously on original basis weight reduction 10% left and right.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
