Abstract
The invention discloses an inverted front shock absorber with a front shock absorber valve system and a rear shock absorber valve system. An inner cavity of a handle tube is arranged as a working cavity, one end of a piston rod (3) is positioned outside the handle tube (1) and connected with one end of a shock absorbing sleeve (2), the other end of the piston rod (3) extends into a damping tube (4) and then extends out of the damping tube (4) to be opposite to a shock absorbing spring (5) arranged in the working cavity of the handle tube (1), shock absorber valve systems and a piston (6) are arranged at the other end of the piston rod (3), and the shock absorber valve systems include the front shock absorber valve system (7) and the rear shock absorber valve system (8) which sleeve the piston rod (3) and are opposite to the shock absorbing spring (5).
Description
Technical field
The present invention relates to a kind of with inverted front shock absorber before front shock absorber valve system and rear shock absorber valve system.
Background technique
The formula front shock absorber of putting is applied on the luxurious racing car of high-performance, go-anywhere vehicle the earliest, due to superior performance, expensive, and some key technologies are difficult to break through, and are not widely used.Handle pipe diameter, the sleeve pipe total length of traditional inverted front shock absorber of current employing are larger, rear shock absorber damper valves is directly transplanted on front shock absorber by inverted front shock absorber, be difficult to be applicable on the common motorcycle of middle small displacement of 125cc ~ 200cc, if by inverted front shock absorber reduction dimensionally, handle pipe inside does not have enough spaces the valve system system of rear shock absorber all to be transplanted into.
Summary of the invention
The invention provides that a kind of it not only increases the travelling comfort of vibration damper with inverted front shock absorber before front shock absorber valve system and rear shock absorber valve system, make velocity curve variation simultaneously, be convenient to regulate.
Present invention employs following technological scheme: a kind of with inverted front shock absorber before front shock absorber valve system and rear shock absorber valve system, it comprises handle pipe, damping sleeve pipe and piston rod, a part for handle pipe is inserted in damping sleeve pipe, the inner chamber of handle pipe is set to active chamber, a part for piston rod is inserted into by the suction side of handle pipe in the active chamber of handle pipe, damp tube is provided with in handle pipe, a part for piston rod is positioned at for outside handle pipe, another part of piston rod inserts in the damp tube be provided with in handle pipe, one end of piston rod is positioned at outside handle pipe, one end of piston rod is connected with damping sleeve pipe one end, the other end of piston rod stretches into that to stretch out damp tube after in damp tube relative with the damping spring be provided with in the active chamber of handle pipe, damped valve system and piston is provided with at the other end of piston rod, damped valve system comprises front shock absorber valve system and rear shock absorber valve system, front shock absorber valve system and rear shock absorber valve system cover are on the piston rod, front shock absorber valve system is relative with damping spring with rear shock absorber valve system.
Described front shock absorber valve system and rear shock absorber valve system are set to rebuilt valve I and rebuilt valve II respectively, and rebuilt valve I and rebuilt valve II are arranged on valve seat I and valve seat II respectively.The side of described valve seat I is provided with boss I, is provided with step hole I in the both sides of boss I, and the side of valve seat II is provided with boss II, is provided with step hole II in the both sides of boss II.On described rebuilt valve I, cover has rebuilt valve spring I, and on described rebuilt valve II, cover has rebuilt valve spring II.
The present invention has following beneficial effect: after have employed above technological scheme, present invention employs the method that front shock absorber valve system and rear shock absorber valve system combine, vibration damper is in compression and restore in stroke, front shock absorber valve system and rear shock absorber valve system work respectively, working procedure is simple, is convenient to regulate.The side of two I of restoring valve seat boss is provided with boss I, and be provided with step hole I in the both sides of boss I, the side of valve seat II is provided with boss II, is provided with step hole II in the both sides of boss II, and operationally fluid circulation is more smooth and easy to make vibration damper like this; The forward and backward damper valve of the present invention is fastened and is all replaced traditional saddle resilient pad with rebuilt valve spring, higher than the sensitivity of saddle resilient pad; The present invention it not only increase the travelling comfort of vibration damper, make velocity curve variation simultaneously, be convenient to regulate.
