Abstract
The utility model discloses an electric vehicle steel plate chassis in the electric vehicle field. The chassis comprises a front axle and a rear axle. Wheels are respectively arranged at two ends of the front axle and two ends of the rear axle. The front axle and the rear axle are fixedly connected through two arc steel plates. Frames are fixedly arranged on the arc steel plates. As the arc steel plates are used for fixedly connecting the front axle and the rear axle, damping effect in the process of running of vehicles is achieved by means of elastic stretching out and drawing back of the arc steel plates, weight of the vehicles is lightened, manufacture cost is lowered, and the chassis can be applied to the chassis field of electric vehicles.
Description
Technical field
The utility model relates to a kind of battery-driven car, particularly a kind of electric vehicle chassis.
Background technology
Four-wheel electric motor car of the prior art comprises propons and the back axle that is fixedly mounted on the chassis, the two ends of propons and back axle all are equipped with wheel, vehicle frame also is installed on the described chassis, four bumpers of described vehicle frame and chassis link to each other, steering hardware also is installed on the described propons, and described back axle middle part is provided with diff, is installed in bumper between vehicle frame and the chassis plays shock-absorbing in the Vehicle Driving Cycle process effect, alleviate jolting of navigating mate, be conducive to improve the traveling comfort of driving.Its weak point is, because this shock mitigation system needs chassis and bumper to be used in conjunction with, this has just increased the weight of vehicle self, thereby has increased energy consumption of vehicles, and has also increased manufacturing cost.
The utility model content
The purpose of this utility model provides a kind of battery-driven car steel plate chassis, has solved deficiency in the prior art, has alleviated the weight of vehicle self, has reduced the energy consumption of vehicle, and has reduced the manufacturing cost of vehicle.
The purpose of this utility model is achieved in that a kind of battery-driven car steel plate chassis, comprise propons and back axle, the two ends of described propons and back axle all are equipped with wheel, are fixed together through two curved plates between described propons and the back axle, are installed with vehicle frame on the described curved plate.
Compared with prior art, the beneficial effects of the utility model are, the utility model adopts curved plate captive joint propons and back axle, original chassis and bumper have been replaced, play the effect of damping in the Vehicle Driving Cycle process by the elastic telescopic of curved plate self, thereby alleviated the weight of vehicle self, reduced energy consumption of vehicles, strengthen the flying power of vehicle, and reduced manufacturing cost.The utility model can be used in the chassis of battery-driven car.
When turning to, curved plate and front axle wheel mutually touch, and guaranteed the stability of structure, described two curved plates and propons, back axle are isosceles trapezoid frame shape structure and are fixed together, and described propons is the upper base of isosceles trapezoid, and back axle is going to the bottom of isosceles trapezoid.
In order to strengthen the damping effect of curved plate, prolong the service life of curved plate, described curved plate is spring plate.
In order further to strengthen the damping effect of curved plate, the width of described curved plate is 40 ~ 50mm, and the thickness of described curved plate is 3 ~ 6mm.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of curved plate in the utility model.
Wherein, 1 propons, 2 curved plates, 3 steering hardwares, 4 wheels, 5 vehicle frames, 6 difies, 7 back axles.
The specific embodiment
A kind of battery-driven car steel plate chassis shown in Fig. 1-2, comprise propons 1 and back axle 7, the two ends of propons 1 and back axle 7 all are equipped with wheel 4, steering hardware 3 also is installed on the propons 1, back axle 7 middle parts also are equipped with diff 6, be fixed together through two curved plates 2 between propons 1 and the back axle 7, two curved plates 2 and propons 1, back axle 7 is isosceles trapezoid frame shape structure and is fixed together, propons 1 is the upper base of isosceles trapezoid, back axle 7 is gone to the bottom for isosceles trapezoid, and curved plate 2 is spring plate, is installed with vehicle frame 5 on the curved plate 2, the width of curved plate 2 is 40 ~ 50mm, and the thickness of curved plate 2 is 3 ~ 6mm.
The utility model adopts curved plate 2 captive joint propons 1 and back axle 7, original chassis and bumper have been replaced, play the effect of damping in the Vehicle Driving Cycle process by the elastic telescopic of curved plate 2 self, thereby alleviated the weight of vehicle self, reduced energy consumption of vehicles, strengthen the flying power of vehicle, and reduced manufacturing cost; Mutually touch when curved plate 2 avoids curved plate 2 and front axle wheel 4 to turn to the isosceles trapezoid frame shape structure of propons 1, back axle 7 compositions, and guaranteed integrally-built stability; The curved plate 2 of selecting spring steel to make has further guaranteed damping effect.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
