Abstract
The utility model relates to a connecting mechanism for a centrifugal involute profile cam, composed of a friction disc, a starting motor spindle, a chassis assemble, a recoil tension spring, an involute cam, a hoof block assemble, etc. The utility model is characterized in that the engagement and the disengagement of the hoof block assemble and the friction disc are controlled through the rotation of the starting motor spindle and the synchronous rotation of the involute cam fixedly connected with the starting motor spindle; as fixedly connected with the friction disc and a magneto, a motorcycle engine is driven to be in the work state through the magneto. The utility model has the advantages of large torque, etc., having no slip and gear engagement noise; the utility model is suitable for various motorcycles provided with the magnetos.
Description
The utility model relates to a kind of centrifugal involute profile cam engagement mechanism, belongs to motorcycle parts class.
All kinds of motorcycles of existing all kinds of charged starting arrangements generally are the import vehicle on the market.Its actuating motor is contained on the position with the crankcase horizontal center line, and this actuating motor has an independent starting gear to be connected with engine crank, and must be situated between between starter gear and actuating motor is provided with free wheel device.Its defective of this mode of structure is: in case after the engine start, starting gear and actuating motor shaftgear still are in engagement, certainly will increase the running noises of motor like this, the transformation of simultaneously also incompatible oblique installing type motorcycle to not charged starting.
In order to overcome the above problems, the inventor had once submitted the model utility (application number: 932352774), propose the involute profile contract block structure that a kind of magnetogenerator axle head that starting electrical machinery is later with throwing off enclosing cover directly links to each other of " a kind of charged starting motorcycle " on December 22nd, 1993.
Practice shows: the charged starting motorcycle according to above conceptual design though cancelled free wheel device in the past, has certain practicality, reliability; But in the moment that starts, the switching of contract piece and contract body can be sent paroxysmal impact noise.Not only give diseases caused by external factors, and easily cause the performance erroneous judgement.
The centrifugal involute profile cam engagement mechanism that the utility model provides its objective is to make starting electrical machinery and start function to carry out steadily to switch, avoid producing sudden impact noise.
This centrifugal involute profile cam engagement mechanism is made up of friction disk, starting electrical machinery axle, chassis combination, returning pull-spring, involute cam, the combination of hoof piece etc., it is characterized in that described friction disk is affixed through face of trying to get to the heart of a matter and magnetogenerator end face, chassis combination, the combination of hoof piece are being set in described friction disk seat; Starting electrical machinery axle with the involute cam clamping is being set in the center hole of chassis combination, and described hoof piece is combined as one group of correspondence and is arranged at, and two are 180 ° of position distribution and are fixed on little axle in the combination of chassis; The combination of two hoof pieces can be rotated around little axle separately, and hoof piece combination outer arc is provided with friction plate; Between the relevant position of two hoof pieces combination, be provided with two returning pull-springs simultaneously.
Centrifugal involute profile cam engagement mechanism according to above conceptual design compares with existing congenerous engaging mechanism, can not only guarantee that electricity starts motorcycle engine and has Maximum Torque, and is non-slip again; Can realize again simultaneously separating thoroughly, in conjunction with firm; And there are not the engagement of mechanical type engagement free wheel device, the bump when throwing away mechanism's engagement to mesh noise.Keep in repair extremely easy to usely, be applicable to the motorcycle of multiple band magnetogenerator.
Accompanying drawing 1 is the utility model structural representation (plane);
Accompanying drawing 2 is the utility model user mode structural representation (section)
Further describe the utility model and provide embodiment below in conjunction with accompanying drawing.
Among the figure 1, friction disk 2, hoof piece combination 3, returning pull-spring 4, involute cam 5, little axle 6, friction plate 7, starting electrical machinery axle 8, chassis combination 9, magnetogenerator end face.
Its concrete structure is that friction disk 1 is affixed through chassis face and magnetogenerator end face 9, and chassis combination 8, hoof piece combination 2 are being set in friction disk dish seat, is being provided with in the center hole of chassis combination 8 with involute cam 4 and is reaching the starting electrical machinery axle 7 of clamping with it.Described hoof piece combination 2 be one group corresponding that be provided with, be all right one way or the other rotation block on two little axles 5 in 180 ° of chassis combinations 8 that distribute and be fixed on; Described hoof piece combination is provided with friction plate 6.Can around between the relevant position of the hoof piece combination 2 that little axle 5 rotates, be provided with two returning pull-springs 3 at two.
Its working principle is as follows:
When starting electrical machinery energising rotation, the involute profile cam 4 that is assemblied on the starting electrical machinery axle 7 just makes hoof piece combination 2 overcome the pulling force of returning pull-spring 3, make two hoof piece assembly parties outwards swing expansion around little axle 5 separately respectively, at this moment hoof piece combination 2 is because involute profile cam 4 and rotation action of centrifugal force, outside diameter is increased, because the effect that the hoof piece makes up 2 edge friction plates makes combination 2 of hoof piece and friction disk 1 inner edge fluid-tight engagement, drive friction disk 1 running.Because trying to get to the heart of a matter of this friction disk 1 is affixed with magnetogenerator end face 9, thereby also drives magnetogenerator run-in synchronism, and and then drive the engine spindle rotation by magnetogenerator, reach the purpose that starts motorcycle.
After motorcycle initiating, turn off start button, the hoof piece combination 2 in the chassis combination 8 is because the disappearance of centrifugal force and the effect of returning pull-spring 3 just recover the home position, and this moment, power was thrown off fully, and motorcycle enters normal operation.
