A kind of motorcycle hydraulic engaging and disengaging gear
Technical field the utility model belongs to motorcycle, the particularly engaging and disengaging gear of motorcycle, definite a kind of motorcycle hydraulic engaging and disengaging gear of saying so.
The friction clutch speed change of the present motorcycle of background technique is very general in the big discharge capacity motorcycle of four-stroke, the hand gear motorcycle of discharge capacity more than the 100-125 cubic millimeter for example, the general clutch mode that adopts traditional handle boom guy type structure, because the spatial constraints of motorcycle self structure, can not make the size of clutch rocking bar more longer, this just needs the cyclist to need sizable operation grip when carrying out the clutch operation, sometimes this steering force in addition reach the 15-30 kilogram or more than, for most of cyclists, clutch, speed change is a very arduous thing, particularly the crowd of the combination area of city and country, if run into the fairground, just need frequent controlled clutch, fatigue very, even may occur the situation of serious accident taking place because clutch is bad.Close the deficiency that structure exists in order to overcome above-mentioned engaging and disengaging gear, inventive concept of the present utility model has been proposed, goal of the invention just of the present utility model provides a kind of motorcycle hydraulic engaging and disengaging gear, has fundamentally overcome the excessive problem of clutch of motorcycle steering force.
This kind of summary of the invention motorcycle hydraulic engaging and disengaging gear, it has clutch rotating shaft [1], the distant bar [2] that is connected with this clutch rotating shaft [1] has a twisted axis [3] at the other end of rocking bar [2], it is characterized in that on twisted axis [3] strand is also connecting the plunger [5] of oil cylinder [6].In order further to enlarge the Applicable scope of this device, so that it can adapt to the more motorcycle of polytypic and structure, the plunger [5] of oil cylinder [6] can twist by a contiguous block [4] and twisted axis [3] on the rocking bar [2] and be connected.The remarkable advantage of this device is, simple in structure, there is not too much annex, install and processing ease, adjustment by suitable oil cylinder compression factor, operation grip on the clutch lever is lowered, hand gear motorcycle for 100-125 series, after adopting this device, operation grip on the clutch lever can drop to the 3-8 kilogram, alleviated cyclist's gripping force greatly, thereby can guarantee the gripping clutch lever of long period, therefore just easily solenoidoperated cluthes be in interlock, semi-linkage and separated state.Separation and combination that the drive form of employing hydraulic pressure comes solenoidoperated cluthes, laborsaving, convenient, be more suitable in the manipulation of the clutch of the motorcycle of discharge capacity greatly, alleviate the cyclist when gear shift because frequently hold with a firm grip, fatigue that loosen the clutch produces, improve the travelling comfort of Safety performance and driving.
Appended drawings 1 is a structural front view of the present utility model, accompanying drawing 2 be the A of accompanying drawing 1 to view, accompanying drawing 3 is schematic representation of oil hydraulic circuit.Sequence number in the accompanying drawing is: 1, clutch rotating shaft, 2, distant bar, 3, twisted axis, 4, contiguous block, 5, plunger, 6, oil cylinder, 7, oilhole, 8, oil box, 9, handle, 10, valve, 11, oil pipe.
Embodiment is with reference to accompanying drawing, and accompanying drawing 1 is equivalent to be installed in the schematic top plan view on the motorcycle.A kind of motorcycle hydraulic engaging and disengaging gear of the present utility model, it has clutch rotating shaft [1], the distant bar [2] that is connected with this clutch rotating shaft [1] has a twisted axis [3] at the other end of rocking bar [2], and the structure of this and present widely used hand gear clutch is basic identical.And the difference of basic feature is also to twist the plunger [5] that is connecting oil cylinder [6] on twisted axis [3].By stretching of plunger [5], control the swing of rocking bar [2], the rotation that drives clutch rotating shaft [1] realizes the separation of clutch internal friction sheet.Further optimized technical scheme is the plunger [5] of oil cylinder [6] to be twisted by a contiguous block [4] and twisted axis [3] on the rocking bar [2] be connected.Like this, not only be fit to the less motorcycle of clutch stroke, and also can adapt to for the clutch of the bigger motorcycle of clutch stroke ratio.Further enlarged the scope of its use.Time spent at that time is connected with oil pipe [11] on being connected clutch lever [9] oilhole [7] on the oil cylinder [6] with valve [10] and oil box [8], with system evacuation, inject hydraulic oil in the oil box [8], suitably adjusts the gap of handle [9], to be fit to operator's hand position.At this moment, if hold handle [9], then valve [10] is opened, hydraulic oil enters oil cylinder [6] along oil pipe [11] by oilhole [7] makes plunger [5] move, and drives rocking bar [2] and moves, and forces clutch rotating shaft [1] to be rotated, and realizes the separation of clutch.When unclamping handle [9], clutch is owing to the normally closed characteristic of himself, and self-return.The situation of semi-linkage also is like this.
