Abstract
The utility model relates to a passenger-car chassis lifting device which comprises a damper, and further comprises a spiral lifter. The spiral lifter is composed of a shell, a turbine nut, a worm, a motor, a movable spring base and a lifting sleeve. The damper is sleeved with the shell, the turbine nut, the worm and the lifting sleeve are arranged in the shell, the lifting sleeve is sleeved with the turbine nut, the edge of the turbine nut is meshed with the worm, the worm is connected with the output end of the motor, the damper is sleeved with the movable spring base, and the movable spring base is fixedly connected with the lifting sleeve. The annular spiral lifter is arranged on the damper of an original car, a passenger-car chassis can be freely lifted according to road conditions, the operation is convenient, the problem that the car can hardly run under the poor road condition is solved, and it is ensured that the original car is unchangeable in safety, controllability and comfort.
Description
Technical field
The utility model belongs to automotive field, relates to a kind of passenger-car chassis jacking system.
Background technology
Automobile, in the process of advancing, often runs into the poor road surface of road conditions, therefore needs bumper to slow down the impact that bring on rugged road surface.Current most of car all adopts MacPherson type suspension, and damping spring is placed in the bumper of former car top, by spring, bears the vertical pressure that vehicle brings, and the upper and lower side of bumper is connecting vehicle frame and wheel respectively, makes vehicle play the effect of damping.But the chassis of car is lower comparatively speaking, lower passenger-car chassis can cause a lot of drawbacks again, such as the bad place of the road conditions such as the road surface rugged or mire, ditch is difficult to normally travel.Therefore, how can regulate the chassis of car, can normally travel in various road conditions is the problem that we will solve.
Summary of the invention
The purpose of this utility model is to provide a kind of passenger-car chassis jacking system, and the chassis that solves car is lower, in the poor problem of carrying capacity of rugged flat road surface and mire, ditch.
The utility model is achieved through the following technical solutions: a kind of passenger-car chassis jacking system, comprise bumper, also comprise toroidal helical lifter, described toroidal helical lifter comprises housing, turbine nut, scroll bar, electrical motor, movable spring seat and jacking sleeve, and wherein, housing is sleeved on bumper, turbine nut, scroll bar and jacking sleeve are housed in housing, turbine nut sleeve on jacking sleeve, the edge of turbine nut and the interlock of scroll bar phase, scroll bar is connected with the mouth of electrical motor again; Movable spring cover for seat is on bumper and affixed with jacking sleeve.
Between described turbine nut and housing, bearing is also housed.
Adopt the good effect of technique scheme: the utility model by settling toroidal helical lifter on the bumper of former car, make the passenger-car chassis can be according to any lifting of the needs of road conditions, and easy to operate, solved car and when road conditions are bad, be difficult to the problem of exercising, also guaranteed simultaneously former car safety, handling, traveling comfort is constant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 bumper, 2 housings, 3 turbine nuts, 4 bearings, 5 scroll bars, 6 electrical motors, 7 movable spring seats, 8 jacking sleeves.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Fig. 1 is structural representation of the present utility model, and as shown in the figure, a kind of passenger-car chassis jacking system, comprises bumper 1, also comprises toroidal helical lifter, to the chassis of car, can carry out lift adjustment.Described toroidal helical lifter comprises housing 2, turbine nut 3, scroll bar 5, electrical motor 6, movable spring seat 7 and jacking sleeve 8, wherein, housing 2 is sleeved on bumper 1, turbine nut 3, scroll bar 5 and jacking sleeve 8 are housed in housing 2, turbine nut 3 is enclosed within on jacking sleeve 8, the edge of turbine nut 3 and scroll bar 5 phase interlocks, scroll bar 5 is connected with the mouth of electrical motor 6 again, therefore can drive turbine nut to rotate by direct motor drive scroll bar, thereby control the up-and-down movement of jacking sleeve.Movable spring seat 7 is enclosed within on bumper 1 and is affixed with jacking sleeve 8, by jacking sleeve, drives movable spring seat to be subjected to displacement, and therefore can change as required the spacing of damper spring and wheel, and then the height between change chassis and road surface.
Between described turbine nut 3 and housing 2, bearing 4 is also housed, mainly plays the effect that reduces friction, turbine nut 3 is rotated smooth and easy.
The utility model in use, when car drives to the bad section of road conditions, open electrical motor, make machine generation forward rotation, can drive scroll bar rotation, then drive the rotation of turbine nut, impel jacking sleeve to rise, passenger-car chassis rises thereupon, makes the car can be than more smoothly by rugged road surface; When car drives to the good section of road conditions, operating motor rotates backward it, drive scroll bar and the turbine nut contrarotation of interlock with it simultaneously, impel jacking sleeve to decline, passenger-car chassis also declines thereupon, so not only guaranteed that car can normally travel when road conditions are bad, and can lower the center of gravity rapidly in the good place of road conditions, guaranteed stability and the safety of vehicle.
