Abstract
The utility model discloses a centrifugal clutch stepless gearbox used for medium and small-sized automotive vehicles and general mechanical driving. The utility model overcomes the problems of which the long lifetime of a v-belt is short and the gearbox easily produces intermittent impact force in acceleration process, etc., in exiting reached technology because the frictional force between the v-belt and a wheel disc is big. When a prime mover encounters braking in high speed run, the output shaft of a driving wheel and the prime mover can disengage from contact immediately, which takes the effect of passing truncation protect action.
Description
The utility model is the used centrifugal clutch type stepless speed variator in the power transmission aspect of medium and small motor vehicle and common mechanical.
In prior art, " the stepless speed regulation power device " that US3266330 described used the centrifugal principle of pendulum and realized moment of torsion, the stepless transformation of rotating speed.But in the power transmission process, exist several defectives:
1, driving wheel because v belt is not tensioned between driving wheel and driven wheel, makes driving wheel be in idling conditions when low speed fortune passes (being idling), and v belt will be subjected to the effect of very big friction this moment, and will be very easily impaired;
2, driving wheel is when quickening, and v belt can produce interrupted impact force, therefore with speed reducer that driven wheel connects in gear also can produce interrupted impact force;
3, when driving wheel runs up, under the situation of brake, since initiatively the wheel disc compressing the pressure of v belt immediately depreciation be minimum value, so v belt will be subjected to bigger pulling force and friction is effect, make shorten the working life of v belt;
4, three directional posts of the control of the orientation on driving wheel slip wheel disc slip, when driving wheel ran up, contacted of directional post and guide sleeve were minimum value, and moment of flexure that directional post is subjected to and friction are maximum values, so directional post is easily impaired.
The purpose of this utility model is exactly to cause problems such as damage for the v belt that overcomes stepless speed variator in the prior art is easily impaired because of discontinuity with directional post, and designs a kind of centrifugal clutch type stepless speed variator.
The utility model is by original machine output shaft, and fixedly wheel disc and slip wheel disc three parts are formed.There is a T shape hole on the top of original machine output shaft, the hole be the screw that has internal thread right overhead.At fixed base of the tight cover of the middle-end of original machine output shaft, and with key and screw.The cylindrical of fixed base has the friction assembly more than two, and the friction assembly is bonded together by spring steel plate and wearing piece and constitutes.One end of friction assembly symmetry separately is bonded on the cylindrical of fixed base, and makes wearing piece outside.Be inserted in oil sealing on the original machine output shaft of fixed base outer side surface, then be inserted in copper sheathing, be inserted in the female axle sleeve of an end at the cylindrical of copper sheathing, original machine output shaft and copper sheathing can both be done relative movement between copper sheathing and the axle sleeve.The fixedly wheel disc of driving wheel is that tightly frame is lived axle sleeve, fixedly the one side of wheel disc is and the corresponding inclined-plane of slip wheel disc, and another side is a hole, the bonding friction steel ring of the inner headed face in hole, the degree of depth in hole is a bit larger tham fixed base, the diameter in hole when fixedly the borehole jack of wheel disc is lived fixed base, leaves suitable space greater than the diameter of fixed base on circumference.The internal thread of axle sleeve termination is corresponding with the outside thread of axle sleeve.Be inserted in the end face that a center oil sealing with holes withstands original machine output shaft in the axle sleeve endoporus, the diameter in this hole is corresponding with the external diameter of fastening screw trip bolt.Fastening screw trip bolt is T-shaped, the center of screw is a through hole, and a termination has oiling chews, and another termination is the corresponding outside thread of screw thread with the inner bolt hole of original machine output shaft end, the diameter of middle-end is just in time corresponding with the diameter of the center hole of swivel nut, can do relative movement.Cylindrical at axle sleeve is inserted in v belt respectively, the slip wheel disc, and sliding sleeve, fixed cover, bowl-shape steel ring and packing ring screw swivel nut, screw fastening screw trip bolt at last, stay a slit between the end face of the screw head of fastening screw trip bolt and swivel nut.Fixed cover is that tightly frame can not be done relative motion tightly on axle sleeve.Three hinged pendulums that are symmetrically distributed are arranged on the slip wheel disc, the inner bolt that is symmetrically distributed more than two, one end of directional post is level and smooth cylinder, the other end is and the corresponding outside thread of inner bolt hole, directional post can be rotated in the inner bolt hole on the slip wheel disc, accordingly the conical through-hole that is symmetrically distributed more than two is being arranged on the fixed cover, there are two above cylindricals to be the awl cylinder accordingly, the center is a guide pin bushing with the corresponding through hole of directional post external diameter, guide pin bushing is inserted respectively in three conical through-holes of fixed cover, then again directional post is inserted in the through hole of guide pin bushing, and be tightened in the screw of slip wheel disc.The length of directional post still can be exceeded with the length that guide pin bushing keeps all contacting when fixedly wheel disc is drawn close with the slip wheel disc.
