Abstract
The utility model discloses a front shock absorber for an electric vehicle. The front shock absorber for the electric vehicle is formed by a shock absorbing rod, an aluminum cylinder, a spring, a hydraulic system, a sealing ring and the like; the spring, the hydraulic system, the sealing ring and the like are arranged inside the aluminum cylinder; movement of the spring and the hydraulic system enables the sliding rod to slide inside the aluminum cylinder to achieve buffering shock absorbing; structures such as a lug piece and a boss which are casted into a whole with the aluminum cylinder are arranged outside the aluminum cylinder to fix parts such as an electric vehicle front mud plate and a front brake; the bottom of the aluminum cylinder is provided with a kidney groove which is used for fixing a front axle; through holes are formed in the upper portion and the perpendicular direction of the kidney groove for installation of a falling prevention device to prevent the front axle from falling off.
Description
Technical field
The utility model relates to a kind of electric accessory motor, particularly a kind of electric vehicle front shock absorber.
Background technique
The electric motor car front shock absorber using at present, it mainly comprises the compositions such as sliding bar, aluminum barrel and spring, hydraulic pressure system, seal ring, has part vibration damper to replace hydraulic pressure system etc. with air pressure system.Current normally used front shock absorber as shown in Figure 1, is made up of 10 sliding bars and 20 aluminum barrels, and spring, hydraulic pressure system, seal ring etc. are arranged in aluminum barrel, and boss 21 is arranged at aluminum barrel bottom, and the through hole that has diameter on boss 21 and be a Φ D is for through electric motor car front axle.According to the difference of service condition, on some front shock absorbers, also have auricle 22, boss 23 and boss 24, on it, have the tapped hole of MA, MB, for fixing of the parts such as front-wheel mud plate; Have on part front shock absorber and also there is boss 25, boss 26, on it, have the through hole that diameter is Φ C, for front butterfly the fixing of device of stopping.When this kind of front shock absorber is used in electric motor car, its front axle can only be that mode from left to right or is from right to left carried out, can not adopt mode from bottom to top to carry out, for the front train of front axle and front-wheel integrative-structure, cannot be arranged in the system being formed by this kind of front shock absorber.
Model utility content
The problem existing for prior art, the purpose of this utility model is to provide a kind of electric vehicle front shock absorber, thus the front-wheel that meets front axle and front-wheel integrative-structure ties up to the demand of installing in electric motor car.
The utility model, for existing particular problem, adopts following solution:
A kind of electric vehicle front shock absorber, formed by sliding bar, aluminum barrel and spring, hydraulic pressure system (or air pressure system), seal ring etc., spring, hydraulic pressure system, seal ring etc. are placed in aluminum barrel, the bottom of aluminum barrel has kidney slot and through hole, the front train of being convenient to front axle and front-wheel integrative-structure installing from bottom to up, thus raise the efficiency.
Brief description of the drawings
Fig. 1 is its structure diagram of existing front damping.
Fig. 2 is the structure diagram of a kind of electric motor car front shock absorber of the utility model embodiment.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, it will be more clear making above-mentioned and other object of the present utility model, Characteristics and advantages.Not drafting in proportion deliberately of accompanying drawing, focuses on illustrating purport of the present utility model.
Fig. 2 is the external structure of a kind of electric vehicle front shock absorber of the utility model specific embodiment, as shown in Figure 2, a kind of electric vehicle front shock absorber of the utility model embodiment, comprise sliding bar 10, aluminum barrel 20 and spring, hydraulic pressure system, seal ring etc., spring, hydraulic pressure system, seal ring etc. are placed in aluminum barrel 20.Auricle 22, boss 23 and the boss 24 in addition of aluminum barrel 20 tops and aluminum barrel integrally casting, on it, have the tapped hole of MA and MB, for fixing front wheel of electric motorcar mud plate and other component, also have and boss 25 and the boss 26 of aluminum barrel integrally casting in aluminum barrel 20 middle and lower parts, on it, have the through hole that diameter is Φ C, for disc brake before fixing.Boss 21 is positioned at aluminum barrel 20 bottoms, have kidney slot 27 from boss 21 to aluminum barrel 20 lower edges, kidney slot top is half hole of diameter of phi D, aluminum barrel lower edge is run through in bottom, have through hole 28 at half bottom, hole distance half centerline hole apart from E place and kidney slot Vertical direction, the diameter of through hole 28 is Φ F, is used for the component such as installing sleeve, bolt, nut, thereby prevents that front axle and front-wheel from coming off from front shock absorber.
In above-mentioned concrete embodiment, preferably, the span of described kidney slot width D and described diameter of phi D is 6～20mm.
Preferably, the span of described E is 6～80mm, and the span of through-hole diameter Φ F is 3～40mm.
The detail of setting forth in above description is so that fully understand the utility model.But above description is only a kind of embodiment of the present utility model, and the utility model can be applied to very eurypalynous vehicular shock absorber, and therefore the utility model is not subject to the restriction of disclosed concrete enforcement above.Any skilled personnel are not departing from technical solutions of the utility model scope situation simultaneously, all can utilize method and the technology contents of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Every content that does not depart from technical solutions of the utility model,, all still belongs in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to technical spirit of the present utility model.
