Abstract
The utility model discloses a variable-speed control mechanism for a motorcycle. The variable-speed control mechanism comprises a variable-speed drum, a first shifting fork and a second shifting fork, wherein the first shifting fork and the second shifting fork are sleeved on the variable-speed drum. A five-star shifting plate is fixed at the left end of the variable-speed drum through a cross countersunk head screw and is connected with a gear shifting arm component. By the aid of the structure, when the motorcycle needs to shift gears, the five-star shifting plate is rotated by driving the gear shifting arm component, so that the variable-speed drum rotates, an annular groove on the variable-speed drum drives the shifting forks to axially move, so that the shifting forks drive a variable-speed gear shaft to axially move to shift the gears, and the variable-speed drum and the five-star shifting plate are reliably and easily connected by the cross countersunk head screw in the structure.
Description
Technical field
The utility model belongs to technical field of motorcycles, is specifically related to a kind of motor bike selector gear.
Background technology
its selector gear variable block working process of present domestic motorcycle automatic clutch engine is as follows: the one, and chaufeur is stepped on gear shift pedal by pin, and moment loading makes it produce rotation in the shifting shaft assembly, the shifting shaft assembly rotarily drive the clutch control arm coaxial rotating that is mounted thereon, thereby make the clutch control arm drive coupled clutch cam plate rotation, circumference uniform distribution arc groove on the clutch cam plate, install by bearing and engine friction clutch coaxial, install on the clutch cam plate with arranging with its groove is corresponding, the clutch push rod body of quantity arc groove, be connected by the power-transfer clutch lifter body between clutch cam plate and clutch push rod body, the steel ball of circumference uniform distribution and clutch cam plate groove respective amount on the power-transfer clutch lifter body, steel ball is positioned at corresponding arc groove just, simultaneously the clutch push rod body fixing with the engine right case lid on.During the rotation of clutch cam plate, act on the clutch push rod body by power-transfer clutch lifter body steel ball, force it to produce axially movable trend, because being fixed on the engine right case lid, can't move the clutch push rod body, thereby outbreak is used for the clutch cam plate, causes the clutch cam plate to move axially, and acts on friction clutch by bearing, produce displacement power-transfer clutch is inner, thereby reach the purpose of cut-off clutch.The 2nd, shifting shaft is after completing above-mentioned working process, be rotated further the gear arm that drives on it and hook plate generation displacement, act on the gearshift finger that is arranged on speed transmission drum, thereby making the gearshift finger drive speed transmission drum rotates, annular groove on speed transmission drum drives gear shift fork and produces and move axially, thereby change gear shaft is moved axially reach the purpose of variable block.
Above-mentioned gearshift is that the automatic separating component of power-transfer clutch (clutch control arm, clutch cam plate, power-transfer clutch lifter body, clutch push rod body etc.) installs cumbersomely, easily produces dislocation, power-transfer clutch lifter body steel ball card during installation less than the phenomenon such as in arc groove; Simultaneously due to structural limitations, when the clutch control arm drove the rotation of clutch cam plate, rotating angle front or back was asymmetric when putting into gear forward and put into gear backward, put into gear before when also causing gearshift and after the stroke of putting into gear inconsistent, also affect simultaneously the separation of power-transfer clutch, cause gearshift ineffective.
The utility model content
For solving above technical matters, the purpose of this utility model is to provide a kind of novelty simple in structure, the motor bike selector gear that speed change is easy to handle.
The technical solution of the utility model is as follows: a kind of motor bike selector gear, comprise speed transmission drum and be sleeved on the first shift fork and the second shift fork on this speed transmission drum, its main points are: be fixed with the five-pointed star plate in described speed transmission drum left part through the crossed countersunk head screw, this five-pointed star plate is connected with gear changing arm component.Adopt above structure, when needing variable block, thereby drive gear changing arm component and realize the rotation of five-pointed star plate, so realize the rotation of speed transmission drum, the annular groove shift fork on speed transmission drum produces and moves axially, and moves axially thereby make shift fork drive change gear shaft the purpose that reaches variable block, in above structure, adopt the crossed countersunk head screw to realize that speed transmission drum is connected connection with the five-pointed star plate, connect reliably, be easy to realize.
Described speed transmission drum left end is connected with check plate through the check plate bolt, is fixed with the aobvious switch movable contact head unit of gear on described check plate bolt.Adopt above structure, on the aobvious switch movable contact head unit of gear the positional representation of each moving contact the means for gear-location of motor-cycle position, rotation along with the driving engine speed transmission drum, means for gear-location of motor-cycle is on different positions, the gear of motor bike can be shown by keeping off aobvious switch movable contact head unit and other equipment, simple in structure, be convenient to install.
Described gear changing arm component comprises moving arm, gear arm and shifting shaft, wherein moving arm one end hook joint is on described five-pointed star plate, the other end and described gear arm are hinged, be connected with spring between this gear arm and moving arm, this spring one end is connected to described upper moving arm, the other end is connected to described gear arm upper end, the described shifting shaft of described gear arm bottom welding.Adopt above structure, stir shifting shaft, thereby make gear arm around rotating with the hinged place of moving arm, the drive gear arm moves, so this gear arm hooks moving five-pointed star plate and rotates, so realize the rotation of speed transmission drum, the annular groove shift fork on speed transmission drum produces and moves axially, and moves axially thereby make shift fork drive change gear shaft the purpose that reaches variable block.
The beneficial effects of the utility model are: the utility model is simple in structure, can realize reliably the shift speed change of motor bike, and is in time efficient, have cost low, be easy to the characteristics such as realization.
