Abstract
The utility model discloses a front shock absorber for motorcycle, which comprises a front fork tube (1), wherein a piston rod (2) and a shock spring (3) are disposed inside the front fork tube (1), a damping spring (4) and a damping sheath (5) are sheathed on the piston rod (2), a fixed seat (6) is disposed between the damping sheath (5) and the damping spring (4), one side of the fixed seat (6) is fixedly supported by the steps on the inner wall of the front fork tube (1), a damping throttling orifice (7) is disposed between the piston rod (2) and fixed seat (6), a free valve (8) is disposed inside the fixed seat (6) and surrounded by the fixed seat (6), the free valve (8) is opposite to the damping throttling orifice, the working chamber in the front fork tube (1) is divided into left and right parts by the free valve (8), the two parts are communicated thought the damping throttling orifice on the piston rod (2) and the space between the free valve (8) and the fixed seat (6), and the free valve (8) is freely and slidingly mated with the piston rod (2).
Description
Technical field
The utility model relates to a kind of front shock absorber of motor bike.
Background technology
The free valve of damping uses partial metallurgy or aluminum alloy materials before the known motor bike, after the motorcycle vibration absorber assembling, manufacturing errors makes piston rod existence inclination in various degree, just occurred with free valve mechanical friction, simultaneously because under specific environment, motion frequency is consistent with the driving engine resonance frequency, can produce " drip, drip " abnormal sound, forms human body sensory unacceptable " noise ".
Summary of the invention
The utility model provides a kind of motorcycle vibration absorber free valve material, and it is not only wear-resisting, oil resistant, heat-resisting, light and handy, and its material property and material cost are better than partial metallurgy or aluminum alloy materials.
The utility model has adopted following technical scheme: a kind of front shock absorber of motor bike, it comprises front fork tube, in front fork tube, be provided with piston rod and damping spring, at upper cover of piston rod damping spring and damping cover are arranged, be provided with permanent seat between described damping cover and the damping spring, one side of permanent seat is a fixed pedestal with the step of front fork tube inwall, between piston rod and permanent seat, be provided with damping orifice, be provided with free valve in the permanent seat, permanent seat surrounds free valve, free valve is relative with damping orifice, free valve is divided into left and right sides two parts with the epitrochoidal chamber in the front fork tube, two parts communicate with gap between the permanent seat by piston rod damping orifice and free valve, and free valve forms to be free to slide with piston rod and cooperates.
Described free valve is the PVC material.Described PVC material is oil-containing PVC.Described damping orifice place is provided with spring leaf, and spring leaf is the saddle type spring leaf.
The utlity model has following beneficial effect: the utility model is provided with free valve, free valve adopts the PVC material to make, so not only can improve wear-resisting, oil resistant, the resistance to heat of free valve, can not be out of shape after long-time the use, and the PVC material is a non-metallic material, the resonance frequency of free valve and piston rod friction its motion frequency of back and driving engine is inconsistent, avoids occurring " drip, drip ", brings comfort for riding of people.
