Abstract
The invention discloses an electric vehicle back damper, which comprises a piston tube, a piston rod, springs and fixed connecting ends at the two ends, wherein the one end of the damper is fixedly arranged on a back wheel, the other end of the damper is fixedly arranged on a vehicle frame, the springs comprise a first spring and a second spring, a threaded connecting element is fixedly arranged on the piston tube, a connecting flange is arranged on the threaded connecting element in a matched way, the lower end of the first spring is fixedly arranged on the connecting flange, the other end of the first spring is fixedly arranged on a connecting circular ring arranged between the first spring and the second spring, the upper end of the second spring is fixedly arranged on a circular disc arranged at the upper end of the piston rod, the goal of regulating the looseness of the first and second springs can be achieved through vertically rotating the connecting flange, the damping effect of the damper is regulated for adapting to different road conditions and passengers, and in addition, the service life reduction of the damper due to the friction between the springs and the piston can be prevented through the connecting circular ring.
Description
Technical field
The present invention relates to electric automobiles, particularly a kind of battery-driven car rear shock absorber.
Background technology
Battery-driven car is as free of contamination walking-replacing tool, be widely used at present, and shock absorber is as the decay accelerating vehicle frame and body vibrations, improve the parts of the stationarity that battery-driven car travels, make requisite parts on battery-driven car, but traditional shock absorber is generally fixed, its effectiveness in vibration suppression is certain, can not regulate for the situation of different road conditions or occupant, and the spring of shock absorber can not do oversize, spring is oversize, easily bends during vibration damping, cause spring and piston rod friction, shorten piston life.
Summary of the invention
The object of the present invention is to provide that a kind of effectiveness in vibration suppression is adjustable, the unbending shock absorber of spring.
For reaching this object, the present invention by the following technical solutions:
A kind of battery-driven car rear shock absorber, comprise piston barrel, piston rod, spring and two ends be fixedly connected with end, described shock absorber one end is fixed on rear wheel, the other end is fixed on vehicle frame on vehicle frame, described spring comprises the first spring and the second spring, described piston barrel is fixed with threaded connector, what described threaded connector coordinated is provided with butt flange, the lower end of described first spring is fixed on butt flange, the other end is fixed on the connection annulus that is arranged between the first spring and the second spring, the upper end of the second spring is fixed on the disk of piston rod upper end.
Further, the density of described first spring is greater than the density of described second spring.
Further, described lower coupling end is integrally fixedly connected on below piston barrel, described upper coupling end is integrally fixedly connected on the clutch disk of piston rod upper end, upper and lower coupling end all offers connecting through hole, and in described connecting through hole, upper and lower coupling end is respectively fixed on rear wheel and vehicle frame by inserting bolt attaching nut.
Further, the side that described threaded connector is outer is provided with scale label.
Further, the left and right sides of the rear wheel of described battery-driven car is provided with described battery-driven car rear shock absorber.
Beneficial effect of the present invention is: described battery-driven car rear shock absorber be provided with first, second spring, the lower end of described first spring is fixed on butt flange, the threaded connector that described butt flange can be arranged on piston barrel moves up and down, thus the elasticity of adjustable springs, realize effectiveness in vibration suppression adjustable, and the spring that two that are connected by coupling link short, solve the long spring of tradition one when vibration damping, spring bending causes spring and piston rod friction problem, improves the life-span of shock absorber.
Accompanying drawing explanation
Fig. 1 is the front elevation of the battery-driven car rear shock absorber that the specific embodiment of the invention provides.
In figure, 1, piston barrel; 2, piston rod; 31, lower coupling end; 32, upper coupling end; 33, connecting through hole; 4, threaded connector; 41, scale label; 5, butt flange; 6, the first spring; 7, the second spring; 8, annulus is connected; 9, clutch disk.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, described battery-driven car rear shock absorber comprises piston, on, lower coupling end 32, 31 and first, second spring 6, 7, described piston comprises piston barrel 1 and piston rod 2, and described lower coupling end 31 is integrally fixed on the below of piston barrel 1, and the clutch disk 9 that described upper coupling end 32 is fixed with piston rod 2 top is integrally fixedly connected with, on described, lower coupling end 32, 31 all offer by connecting through hole 33, and described on, lower coupling end 32, 31 are separately fixed on rear side wheel and vehicle frame by the bolt inserted in connecting through hole 33, the outside of described piston barrel 1 is fixed with threaded connector 4, and the outer side of threaded connector 4 is provided with scale label 41, described threaded connector 4 is also arranged with and can moves up and down thereon and the butt flange 5 fixed, described first, second spring 6, 7 are enclosed within described piston, the lower end of described first spring 6 is fixed on butt flange 5, the other end is fixed on the connection annulus 8 that is enclosed within the middle part of piston, and the lower end of the second spring 7 is also fixed on described connection annulus 8, and the other end is fixed on the fixing clutch disk 9 in piston rod 2 upper end.
The density of described first spring 6 is greater than the density of the second spring 7, by the spring in conjunction with two kinds of different densities, shock absorber effectiveness in vibration suppression can be made more gentle.
The left and right sides of described trailing wheel is all fixed with described rear shock absorber, the scale label 41 of described threaded connector 4 arranged outside, regulate shock absorber time, can be adjusted on same position according to the rear shock absorber of the instruction of scale label 41 by trailing wheel both sides.
The rear shock absorber of described battery-driven car is when regulating, regulate by rotating up-down adjustment butt flange 5, described butt flange 5 rotates up, then first, second spring 6,7 tightens up, the good damping result of shock absorber, can adapt to the road conditions of comparatively jolting and the heavier people of band or thing, described butt flange 5 is rotated down, then first, second spring 6,7 loosens, and the effectiveness in vibration suppression of shock absorber is general, can adapt to more smooth road conditions and be with lighter people or thing.
Below only describe the present invention with embodiment, but the present invention is not limited to above-mentioned size and outward appearance illustration, more should form any restriction of the present invention.As long as any improvement do the present invention or modification all belong within the protection domain of the claims in the present invention opinion.
