Abstract
The utility model provides an electromagnetically controlled cone-ring type continuously variable transmission clutch and reverse gear device. The device comprises an electromagnetic coil, an electromagnetic coil support, a gag bit ring, a shaft, a fixing plate, a compression plate, a friction ring, a planet carrier, a gear ring, a planet wheel and a sun wheel, wherein the gear ring and the planet carrier are bonded on the shaft through the bearing and the sun wheel by splines; the fixing plate is circular-ring-shaped and is fixed on a transmission shell; a friction plate and the electromagnetic coil are fixed on the fixing plate; a butterfly spring is fixed on the planet carrier; the ring-shaped compression plate is fixed on the outer ring of the butterfly spring; the gag bit ring is fixed on the left end face of the butterfly spring; and the ring-shaped friction ring is fixed on the gear ring. The working principle is as follow: when an internal combustion engine works, the compression plate compacts on the friction ring under the action of the elasticity of the butterfly spring; the gear ring and the planet carrier are combined, and the power is transmitted to the cone-ring type continuously variable transmission through the gear ring. When a vehicle is started, the electromagnetic coil is electrified to attract the gag bit to drive the outer ring of the butterfly spring and the compression plate to swing leftwards, the compression plate breaks away from the friction ring; at this time, the planet carrier rotates freely, the power transmission is broken at the place. When a gear shifting operation rod is arranged at a reverse gear position, higher current is introduced to the electromagnetic coil, the compression plate is driven to swing leftwards further so as to combine the planet carrier with the fixing plate, and the planet carrier does not rotate; the gear ring rotates reversely relative to the sun wheel so as to back a car.
Description
Technical field
The utility model relates to clutch and the reverse gear apparatus of the conical ring formula that the is applicable to buncher in a kind of vehicle drive system.
Background technique
Conical ring formula stepless speed variator is a kind of stepless speed variator by friction driving, from working principle, belongs to CVT speed changer, only with simple and durable parts, realizes pure machinery and controls.Compare and aspect manufacture cost and efficiency, having obvious advantage with traditional C VT stepless speed variator.With the clutch that conical ring formula stepless speed variator matches, generally adopt dry clutch as starting element; Yet in actual driving procedure, dry clutch engaging process easily causes that vehicle is flame-out, and using fluid torque converter instead can not only increase cost but also lower efficiency.
Model utility content
The purpose of this utility model is to provide a kind of stepless speed variator clutch of conical ring formula and reverse gear apparatus of Electromagnetic Control, and this device is by former conical ring formula stepless speed variator clutch and reverse gear apparatus and be integrated; Mechanical handling is become to Electromagnetic Control, and not only clutch is more smooth-going, avoids clutch's jointing process to cause that vehicle is flame-out, also makes clutch and the more convenient operation of reversing gear.
Structure of the present utility model is comprised of electromagnetic coil, electromagnetic loop bracket, armature ring, axle, fixed tray, platen, friction ring, planet carrier, gear ring, planet wheel, sun gear.Wherein, axle is made stepped shaft, is connected with I. C. engine crankshaft; Gear ring, planet carrier are loaded on axle by spline by bearing, sun gear; Gear ring, planet wheel, sun gear are intermeshing, and planet wheel links together by planet wheel shaft and planet carrier.Fixed tray is ring, is fixed on case of transmission, by spline, is loaded on axle; Gear ring, planet wheel, sun gear are intermeshing, and planet wheel links together by planet wheel shaft and planet carrier.Fixed tray is ring, is fixed on case of transmission, and right side fixed friction sheet, electromagnetic loop bracket is fixed on fixed tray, for electromagnetic coil is installed, and doubles as yoke; Fixing butterfly spring on the left side of planet carrier, butterfly spring outer ring stationary annular platen, fixed armature ring on the left side of butterfly spring.Stationary annular friction ring on the left side of gear ring.
Working principle: during internal combustion engine, the power of internal-combustion engine passes on axle, platen is pressed on friction ring under the effect of butterfly spring power; Frictional force combines platen and friction ring.Now, gear ring and planet carrier combine; Planet carrier, gear ring, planet wheel, the synchronized rotation of sun gear, by gear ring, to conical ring formula stepless speed variator transferring power, when vehicle launch, electromagnetic coil is switched on; The electromagnetic attracting force armature ring that electromagnetic coil produces swings butterfly spring outer ring and platen left, and platen and friction ring disengage; Now planet carrier freely rotates; Transmission of power is interrupted herein, be equivalent to clutch " from ".The size of current of controlling in electromagnetic coil can be controlled clutch speed, makes to start smooth-going.When gear shift operation bar is when reversing gear position, electromagnetic coil passes into larger electric current; The electromagnetic attracting force armature that electromagnetic coil produces further swings butterfly spring outer ring and platen left, and platen contacts with the friction plate on fixed tray right-hand member; Planet carrier and fixed tray are combined, and planet carrier does not rotate.Be equivalent to planetary gear train planet carrier and fix, planet wheel rotates with sun gear, drives the relative sun gear of gear ring to rotate backward, and realizes reversing.
The good effect of generation of the present utility model is by former conical ring formula stepless speed variator clutch and reverse gear apparatus and is integrated; Mechanical handling is become to Electromagnetic Control, and not only clutch is more smooth-going, avoids clutch's jointing process to cause that vehicle is flame-out, also makes clutch and the more convenient operation of reversing gear, structure more simply, manufacture lower
