Abstract
The utility model discloses an electric vehicle chassis which comprises a front axle, a cross beam, a rear axle and an underframe, wherein the cross beam is composed of two elastic beams arranged in parallel; the elastic beam comprises an arc-shaped elastic steel plate wrapped inside and an elastic rubber layer at the outer part; a rotary pair is arranged at the front ends of the two elastic beams; the rotary pair is hinged with the front axle; the rear ends of the two elastic beams are in cup joint with a sliding sleeve matched with the elastic beams and capable of sliding on the elastic beams; the sliding sleeve is fixedly connected with a fixing block; the fixing block is connected with the rear axle; a screw hole is formed in the lower surface of the sliding sleeve; a locking screw rod is in threaded connection in the screw hole; an elasticity adjusting beam and an underframe support beam are arranged at the middle part of the elastic beam; sliding sleeves matched with the elastic beams and capable of sliding on the elastic beams are arranged at the two ends of the elasticity adjusting beam and the underframe support beam respectively; screw holes are formed in the sliding sleeves; locking screw rods are in threaded connection in the screw holes; the underframe support beam is fixedly connected with the underframe; and the underframe is in lap joint with the elasticity adjusting beam. The electric vehicle chassis has excellent shock resistance and avoids noise.
Description
Technical field
The utility model relates to a kind of battery-driven car parts, relates in particular to a kind of electric vehicle chassis.
Background technology
In the prior art, the chassis of electric cycle all adopts rigid construction, in order to reduce the impact of the vibrations of the middle vehicle that travels on human body, improve the traveling comfort of passenger, the way that generally all adopts below seat mounting shock absorber or add damping spring, although this way has solved damping problem, but whole vehicle frame, the vibrations that comprise headstock are still quite strong, and the complex structure of car, conducts oneself with dignity and increase simultaneously.For this reason, people have invented a kind of electric vehicle chassis of cushioning effect that supports to play as crossbeam with arc elastic steel plate, but because the vibrations of this tare are supported by arc elastic steel plate entirely, this just causes elasticity and the toughness deficiency of arc elastic steel plate, this electric vehicle chassis is short service life, the noise contacting with base plate during the vibrations of arc elastic steel plate is large, and the elastic regulating structure setting range on this arc elastic steel plate is little, the easy automatic movable of adjust bar, degree of regulation is low, structure that cannot the whole electric vehicle chassis of fine adjustment connects, disqualification rate after production is high, promote productive costs.
Utility model content
For solving the problems of the technologies described above, the utility model has designed a kind of long service life, and noise is low, regulates electric vehicle chassis easy to assembly.
The utility model adopts following technical scheme:
A kind of electric vehicle chassis, comprise propons, crossbeam, back axle and underframe, crossbeam consists of the elastic beam of two parallel placements, elastic beam comprises and is wrapped in inner arc elastic steel plate and outside elastic rubber layer, two elastic beam front ends are provided with revolute pair, revolute pair and propons are hinged, two elastic beam rear ends are socketed with and coordinate the slip cap that can slide in elasticity Liangshan with elastic beam, on slip cap, be fixedly connected with fixed block, fixed block is connected with back axle, slip cap lower surface is provided with screw, screw negative thread is connected with tie down screw, elastic beam middle part is provided with flexible adjustment beam and underframe support beam, flexible adjustment beam and underframe support beam two ends are respectively arranged with and coordinate the slip cap that can slide in elasticity Liangshan with elastic beam, on slip cap, be provided with screw, screw negative thread is connected with tie down screw, on underframe support beam, be fixedly connected with underframe, underframe and flexible adjustment beam overlap joint.
As preferably, on described tie down screw, be provided with the swing handle of T shape.
As preferably, described flexible adjustment beam outside face is enclosed with one deck elastic rubber layer.
Compared with prior art, the utility model has the advantages that: most of weight of rider and car load is all pressed on crossbeam, the shaking force causing due to road injustice when vehicle to run all can sponge by the arc elastic steel plate of elastic beam inside and outside elastic rubber layer, there is fabulous shock resistance, effect due to elastic rubber layer, during vibrations, elastic beam contacts and does not substantially produce noise with other positions, and by coordinate the setting of the slip cap that can slide in elasticity Liangshan with elastic beam, can facilitate and regulate according to demand underframe support beam, the position that flexible adjustment beam and back axle are installed, thereby play different anti seismic efficiencies, and the effect of accurately installing, promote production qualification rate, reduce costs.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of structural representation of crossbeam inside in the utility model;
In figure: 1, crossbeam, 2, propons, 3, underframe support beam, 4, underframe, 5, revolute pair, 6, slip cap, 7, tie down screw, 8, fixed block, 9, back axle, 10, flexible adjustment beam, 11, arc elastic steel plate, 12, elastic rubber layer.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: as shown in Figures 1 and 2, a kind of electric vehicle chassis, comprise propons 2, crossbeam 1, back axle 9 and underframe 4, crossbeam consists of the elastic beam of two parallel placements, elastic beam comprises and is wrapped in inner arc elastic steel plate 11 and outside elastic rubber layer 12, two elastic beam front ends are provided with revolute pair 5, revolute pair and propons are hinged, two elastic beam rear ends are socketed with and coordinate the slip cap 6 that can slide in elasticity Liangshan with elastic beam, on slip cap, be fixedly connected with fixed block 8, fixed block is connected with back axle, slip cap lower surface is provided with screw, screw negative thread is connected with tie down screw 7, elastic beam middle part is provided with flexible adjustment beam 10 and underframe support beam 3, flexible adjustment beam and underframe support beam two ends are respectively arranged with and coordinate the slip cap that can slide in elasticity Liangshan with elastic beam, on slip cap, be provided with screw, screw negative thread is connected with tie down screw, on underframe support beam, be fixedly connected with underframe, underframe and flexible adjustment beam overlap joint, on tie down screw, be provided with the swing handle of T shape, flexible adjustment beam outside face is enclosed with one deck elastic rubber layer.
Compared with prior art, the utility model has the advantages that: most of weight of rider and car load is all pressed on crossbeam, the shaking force causing due to road injustice when vehicle to run all can sponge by the arc elastic steel plate of elastic beam inside and outside elastic rubber layer, there is fabulous shock resistance, effect due to elastic rubber layer, during vibrations, elastic beam contacts and does not substantially produce noise with other positions, and by coordinate the setting of the slip cap that can slide in elasticity Liangshan with elastic beam, can facilitate and regulate according to demand underframe support beam, the position that flexible adjustment beam and back axle are installed, thereby play different anti seismic efficiencies, and the effect of accurately installing, promote production qualification rate, reduce costs.
Above-described embodiment is a kind of preferably scheme of the present utility model, not the utility model is done to any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim records.
