Background technology
Electric car, i.e. electric drive vehicle, also known as electricity are driven.Electric car is divided into alternating current electric vehicle and DC electric car.Generally
The electric car said is originated using battery as energy, by parts such as controller, motors, converts electrical energy into mechanical energy motion,
Change the vehicle of speed with control electric current size.Shock absorber be mainly used to suppress spring shock-absorbing after rebound when concussion and from road
The impact in face.When by uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, but spring itself also has back and forth
Motion, and shock absorber jumps for suppressing this spring.Shock absorber is too soft, vehicle body will vertical bounce, shock absorber is too
It is hard to can bring about too big resistance, hinder spring normal work.In the retrofit process on suspension, hard shock absorber will
Mutually arranged in pairs or groups with hard spring, and the hardness of spring and car weight are closely bound up, therefore heavier car typically uses harder shock-absorbing
Device.With drawing the device that shake bent axle connects, for the torsional shaking for the bent axle that contends with（I.e. bent axle subject cylinder igniting impulsive force and twist
Phenomenon）.
Shock absorber of the prior art carries out shock-absorbing only with a spring, and shock-proof effect is poor, needs further complete
It is kind, and small sleeve, when being slided in big sleeve, lubricating oil is not easy to enter, and during long-term use, small sleeve is easily ground
Damage, reduce its service life.
Utility model content
The purpose of this utility model is that there is provided a kind of electric car shock absorber in order to overcome the deficiencies in the prior art.
The utility model is to be achieved through the following technical solutions：
A kind of electric car shock absorber, including upper hanger, lower hanger, support column, big sleeve, small sleeve, described upper hanger
Installed in the upper end of support column, spacing sleeve column is installed that one end away from upper hanger in the support column, in the spacing sleeve column
Lower surface disc is installed, and big sleeve is installed in the lower end of the support column, is slidably fitted with the big sleeve
Small sleeve, the small sleeve is connected through the spacing collar and with the lower hanger；The big sleeve and small sleeve constitute two grades and stretched
Contracting bar structure, and inner spring is cased with outside two grades of Telescopic rod structures, it is cased with outer spring in the outside of the inner spring；Described
Oblique oilhole is machined with the outside wall surface of support column, the oil inlet of the oblique oilhole is arranged in the outside wall surface of support column, tiltedly
Communicated to the oil-out of oilhole with the oil groove inside the support column, and the oil groove is communicated with big sleeve inner, and
The first oil baffle and the second oil baffle are provided with the inwall of the oil groove.
Further, two positive stop lug boss are symmetrically arranged with the outer surface of the support column, and the positive stop lug boss is used
It is spacing in being carried out to spacing sleeve column.
Further, one end contact of the inner spring is in the lower surface of the disc, and other end contact is described spacing
On the inner face of the collar, one end contact of the outer spring is in the lower surface of the disc, and other end contact is in the stop collar
On the inner face of ring.
Further, the inner spring and outer spring are helical spring, and the inner spring and outer spring are used
Stainless steel material is made.
Compared with prior art, the beneficial effects of the utility model are：The utility model when in use, by being provided with
Upper hanger and lower hanger, so as to whole shock absorber is arranged on electric car by hanger, by being provided with inner spring and outer bullet
Spring, it is possible to increase the damping effect of whole shock absorber, by being provided with positive stop lug boss, be easy to carry out spacing sleeve column it is spacing, from
And prevent inner spring and outer spring from occurring the position changing of the relative positions；By being provided with oblique oilhole and oil groove, oil groove and big sleeve inner phase
It is logical, it is easy to lubricating oil to enter in big sleeve, can effectively prevents the abrasion of small sleeve, improve service life, by sets
There are the first oil baffle and the second oil baffle, can prevent lubricating oil from being flowed back from big sleeve.
