Abstract
A front fork for damping device for a bicycle or an electro motorcar comprises a damping device which is respectively connected with the front fork and a handle straight tube. The upper end of the front fork is provided with a sleeve. A guiding slide base is fixedly disposed on the upper part of the sleeve. A slide groove which crosses through the guiding slide base is axially disposed on the guiding slide base. The end of the slide groove is not round. The lower end of the handle straight tube is fixedly connected with a slide bock. The slide block is slidingly disposed in the slide groove. The lower end of the damping device is disposed in the sleeve and the upper end is disposed in the slide block or the handle straight tube. The damping device is a damping spring. The inner bottom of the sleeve is provided with a locating pole which is connected with the lower end of the damping spring. A sleeve hole is axially disposed on the slide block corresponding to the damping spring. The upper end of the damping device penetrates through the sleeve hole and is inserted into the handle straight tube for locating and connecting. The utility model hides in damping spring in the sleeve of the front fork and the slide block which efficiently prevents the spring from being exposed to wind and rain and prolongs the service life of spring. The structure thereof is compact, the swerving is flexible, the manufacturing cost is low and the front fork is beautiful and useful.

The utility model content
The purpose of this utility model aims to provide a kind of compact conformation, good damping effect, bicycle that the cost cost is low, handsome in appearance or the front fork shock absorption device of battery-driven car, to overcome the deficiencies in the prior art.
By the front fork shock absorption device of a kind of bicycle of this purpose design-calculated or battery-driven car, comprise respectively and front fork and handle straight tube bonded assembly shock absorption device; The front fork upper end is provided with sleeve, and upper cartridge is set with the guiding slide, axially is provided with on the guiding slide to run through its chute at two ends up and down, and the chute end face is non-circular; Handle straight tube lower end is set with slide block, and slide block is slidingly arranged in the chute; Its architectural feature is that the shock absorption device lower end is arranged in the sleeve, and the upper end is arranged in slide block or the handle straight tube.
Described shock absorption device is a damping spring, and the sleeve inner bottom surface is provided with registration mast, joins with location, damping spring lower end; The corresponding damping spring of slide block axially is provided with trepanning, and trepanning is passed in the shock absorption device upper end, and stretches in the handle straight tube and be located by connecting.
Described slide block all is dovetail form with the chute of guiding slide; The slide block lower end is provided with the anticreep baffle plate, and with guiding slide spacing joining of lower end, the upper end is provided with connector, captives joint with handle straight tube lower end.
The connector of described slide block and handle straight tube lower end inwall interference fit, handle straight tube and connector junction also clamp and are provided with clamp.
Described guiding slide lower surface also is provided with exhaust slot.
Described front fork and handle straight tube junction also are arranged with dust protecting cap.
The Front brake joint pin is extended in the fork pin front end face middle and upper part of described front fork; Perhaps, the barrel forward end face middle and lower part of front fork is provided with the Front brake connecting bore.
The utility model is hidden damping spring and is arranged in the sleeve and slide block of front fork, effectively avoids spring to expose to wind and rain, and exposes to the sun and rain, and improves spring service life.Its compact conformation, turn to flexibly, the cost cost is low, attractive and durable.
