Abstract
The utility model discloses an improved shock absorber for a front fork of an electric vehicle. The improved shock absorber for the front fork of the electric vehicle comprises a shock absorber sleeve, a shocker absorber shaft and an oiling device, wherein the front end of the shock absorber shaft is arranged inside the shock absorber sleeve; the front end of the shock absorber shaft can move up and down inside the shock absorber sleeve in a telescopic manner; the oiling device is arranged on the shock absorber sleeve; the oiling device is internally opened in a gap between the shock absorber sleeve and the shock absorber shaft; and the axis of the oiling device is vertical to that of the shock absorber shaft. The oiling device is arranged on the shock absorber sleeve, so that lubricating oil can be conveniently added in a riding process; and moreover, the shaft sleeve abrasion caused by the shortage of lubricating oil for a common shock absorber is reduced, a shock absorbing effect of a common front fork is strengthened, and the service life of the common front fork is prolonged.
Description
Technical field
The utility model relates to the Electrical Bicycle technical field, relates in particular to a kind of improved front fork of electric vehicle shock absorbing apparatus.
Background technology
The battery-driven car industry is started late in China's development, a lot of battery-driven car enterprises are made the transition by bicycle manufacturing enterprise, industry technology level integral body is on the low side, motor bike prior art parameter is just used for reference in the vehicle design of battery-driven car, simply improve according to traditional experience, the analysis method of the science that has no basis for the technical parameter characteristic of battery-driven car, adopts scientific approach to carry out unit design.Along with China's battery-driven car market owning amount above 1.2 hundred million, and constantly increase with annual 2000 ten thousand speedup, along with the go to the countryside beginning of process of battery-driven car, how to ensure more than one hundred million customers' driving safety, how to ensure that the battery-driven car of going to the countryside adapts to the road surface of jolting, rural area, becomes key subjects of battery-driven car industry.
Battery-driven car requires to accomplish safety as the popular vehicle, and is comfortable, reliable.For relaxing impact and the vibrations that are subject to because road is uneven in the process of moving with the decay battery-driven car, guarantee the steady and comfortable of driving, be conducive to improve the safety of battery-driven car, traveling comfort, electric service life and road-holding property, generally the front fork at battery-driven car arranges Shock absorber, this Shock absorber mainly is made of shock-proof casing and the shock-absorbing shaft that is positioned at shock-proof casing, in order to reduce the wearing and tearing of shock-proof casing and shock-absorbing shaft, improve damping effect and the service life of battery-driven car, when shock-proof casing and shock-absorbing shaft are installed, between shock-proof casing and shock-absorbing shaft, add lubricating oil, prolongation along with the time of riding, the minimizing of lubricating oil, strengthened the wearing and tearing of shock-proof casing and shock-absorbing shaft, and can easily not add lubricating oil this moment again.
Summary of the invention
The purpose of this utility model is for the above problem that existing front fork of electric vehicle Shock absorber exists, provide a kind of can be at any time, convenient improved front fork of electric vehicle Shock absorber toward adding lubricating oil between shock-proof casing and the shock-absorbing shaft.
The purpose of this utility model is achieved through the following technical solutions, this front fork of electric vehicle Shock absorber comprises shock-proof casing, shock-absorbing shaft, oiling device, the front end of described shock-absorbing shaft is positioned at shock-proof casing, the front end of described shock-absorbing shaft can be made up and down fore and aft motion in shock-proof casing, describedly be provided with an oiling device at shock-proof casing, described oiling device inner opening is in the gap of shock-proof casing and shock-absorbing shaft, and the axis of described oiling device is perpendicular to the axis of shock-absorbing shaft.
The utility model can also have another kind of embodiment, namely enter the gap of shock-proof casing and shock-absorbing shaft for the convenient lubricating oil fast speed that injects from oiling device, the axis of described oiling device and the axis of shock-absorbing shaft acutangulate, and namely oiling device is an inclined hole that tilts from the top down.
Preferably, the axis of described oiling device becomes miter angle with the axis of shock-absorbing shaft.
When battery-driven car is ridden a period of time discovery shortage lubricating oil, can in Shock absorber, inject lubricating oil by oiling device timely, convenient and practical.
The beneficial effects of the utility model are: owing to be provided with oiling device at shock-proof casing, in the process of riding, can add easily lubricating oil, common Shock absorber causes axle sleeve because lacking lubricating oil wearing and tearing have been reduced, strengthen the shock-proof effect of common front fork, prolonged the service life of common front fork.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
Fig. 1 is cutaway view of the present utility model
Fig. 2 is the cutaway view of the another kind of embodiment of the utility model
Among the figure: 1, shock-proof casing 2, shock-absorbing shaft 3, oiling device
The specific embodiment
As shown in Figure 1, this front fork of electric vehicle Shock absorber comprises shock-proof casing 1, shock-absorbing shaft 2, oiling device 3, shock-proof casing 1 is the cylindrical shape of upper shed, the front end of shock-absorbing shaft 2 is positioned at columnar shock-proof casing 1, the front end of shock-absorbing shaft 2 is fore and aft motion about shock-proof casing 1 interior can the work, be provided with an oiling device 3 at shock-proof casing 1, oiling device 3 inner openings are in the gap of shock-proof casing 1 and shock-absorbing shaft 2, and the axis of oiling device 3 is perpendicular to the axis of shock-absorbing shaft 2.
As shown in Figure 2, show another kind of embodiment of the present utility model, namely oiling device 3 is an inclined hole that tilts from the top down at shock-proof casing 1, and the axis of oiling device 3 becomes miter angle with the axis of shock-absorbing shaft 2.The lubricating oil fast speed that can conveniently inject from oiling device 3 like this enters the gap of shock-proof casing 1 and shock-absorbing shaft 2.
