Description
Technical field:
The utility model relates to clutch device, specifically is the planetary gear clutch device with stepless change and two kinds of functions of clutch.
Background technique:
At present in the clutch that vehicle uses, most of clutches are friction clutcch, and friction clutcch is complex structure not only, and are easy to generate clutch friction plate and skid, and service behaviour is not very stable.Application number is that 200520053737.6 Chinese patent discloses a kind of planetary pinion clutch, though its stable work in work, moment does not have the waste of transmission yet, and it also is that a kind of friction mode is controlled clutch, and clutch state is difficult to control.
The model utility content:
The purpose of this utility model is that a kind of planetary gear clutch device of realizing stepless change and two kinds of functions of clutch with oil hydraulic motor control constraint planetary gears will be provided.
The purpose of this utility model realizes by following technical proposals:
The utility model device is made up of planetary gears and oil hydraulic motor, the moment output shaft of oil hydraulic motor, connect in conjunction with three primary elements of planetary gears---sun gear by transmission device, gear ring, in planetary pinion and the planetary carrier any one makes it to do and is subjected to control, other two primary elements are done driving link and driven member as required respectively, driving link is connected with pto, driven member is connected with load, just can control the control that is subjected to of planetary gears by the moment size of control oil hydraulic motor output, to being subjected to control or fixing or constrained, make planetary gears present different drive states, realize " clutch " between planetary gears driving link and the Passive part, the stepless change of " half-clutch " and certain limit.
Described planetary gears is a prior art, planetary gears is arranged in the casing or is installed in the casing of automatic transmission case, or be installed in the casing of motor, the power input and output shaft is by the bearings on the casing, and being subjected to of planetary gears also is provided with positioning bearing and positions between control and the casing.
The transmission device of described oil hydraulic motor control force is gear transmission or is chain-driven.
The control of oil hydraulic motor is by SCM system, the brake switch sensor, vehicle speed sensor, throttle sensor, solenoid directional control valve, the electromagnetic speed-adjusting valve, one-way valve, relief valve, accumulator and fuel tank are formed, solenoid directional control valve, the control end of electromagnetic speed-adjusting valve is connected with SCM system, control by SCM system, advancing of 2 oil outlets of solenoid directional control valve and oil hydraulic motor, oil outlet is connected by oil pipe, 2 one of them hydraulic fluid ports of filler opening of solenoid directional control valve are connected with fuel tank by oil pipe, another hydraulic fluid port is by oil pipe and electromagnetic speed-adjusting valve, accumulator. the oil outlet of relief valve filler opening and one-way valve is connected, another hydraulic fluid port of electromagnetic speed-adjusting valve, the filler opening of one-way valve, the oil outlet of relief valve is connected with fuel tank by oil pipe, throttle sensor, vehicle speed sensor, the brake switch sensor is connected with monolithic system.
Now with the gear that installs on the hydraulic motor output shaft be packed in the gear of gear ring outer and be meshed with the gear ring concentric, gear ring is subjected to control, sun gear is made driving link, its axle links to each other with engine output shaft, planet carrier is made driven member, and its axle is connected to example explanation clutch working procedure with back level manual transmission:
Clutch can be realized control clutch automatically by gas pedal, and during engine start, vehicle brake pedal and gas pedal are not all stepped on, and brake switch sensor, throttle sensor do not have electrical signal input SCM system.SCM system control electromagnetic speed-adjusting valve standard-sized sheet, the control solenoid directional control valve is in right position, and the rotation of motor makes the gear ring of planetary gears drive the oil hydraulic motor rotation, makes it to be operated in the pump operating mode, therefore rotating speed is lower the time, the oily flow of oil hydraulic motor output is less, and oil can flow through the electromagnetic speed-adjusting valve in non-resistance ground, and oil hydraulic motor does not have resistance, gear ring can rotate freely, clutch " from " state, power can not output to manual transmission, this moment can hang up 1 grade.When stepping on the throttle, single-chip microcomputer detects the electrical signal of throttle sensor feedback and the speed of a motor vehicle electrical signal of vehicle speed sensor, if the speed of a motor vehicle is 0 or very low, then SCM system control electromagnetic speed-adjusting valve closes small flow, it is following more that throttle is stepped on, SCM system is just controlled the electromagnetic speed-adjusting valve and is closed more for a short time, but can not close dead, make the not dead fire of motor, increasing along with throttle, rotating speed increases, and the oil mass of oil hydraulic motor output also increases, but the flow that the electromagnetic speed-adjusting valve allows is more and more littler, so the resistance of oil hydraulic motor just increases, when the resistance of oil hydraulic motor greatly when stoping gear ring motionless, clutch is in " closing " state, motor drives vehicle and advances, when the electrical signal that detects vehicle speed sensor feedback when SCM system reaches certain value, SCM system control electromagnetic speed-adjusting valve cuts out fully, makes clutch complete " closing ", finishes one grade of starting-up process.When the speed of a motor vehicle reaches very fast, as long as gas pedal is unclamped, when SCM system detects less than the signal of throttle sensor, SCM system is just controlled electromagnetic speed-adjusting valve standard-sized sheet, make clutch " separation ", can manually hang up required gear this moment according to the speed of the speed of a motor vehicle, depress gas pedal again, after SCM system detects, again according to the size of the electrical signal of the electrical signal of throttle sensor and vehicle speed sensor, the flow of electromagnetic speed-adjusting valve is turned down gradually, if the vehicle speed sensor of this moment has vehicle speed signal, and when reaching certain higher speed of a motor vehicle, then SCM system control electromagnetic speed-adjusting valve cuts out fully, make clutch complete " closing ", the power of motor can all output to the driving wheel of back from planet carrier.When wanting Brake stop, step on brake petal, after SCM system detects the electrical signal of brake switch sensor, the control solenoid directional control valve is in position, a left side, utilize the motor braking that creates a diversion, improve retardation efficiency, because of the torsion of oil hydraulic motor output has unidirectional, motor can be extremely not fiery, come to a complete stop behind the vehicle, lift brake petal, SCM system is just controlled solenoid directional control valve in right position, control electromagnetic speed-adjusting valve standard-sized sheet, make clutch be in " from " state.It is too high that relief valve can limit oil pressure, and accumulator can absorb the hydraulic pressure impact force, thus protection clutch and motor.One-way valve can make clutch appliance that unidirectional force-transfer characteristic is arranged, thereby can save fuel oil, improves retardation efficiency.
Advantage of the present utility model is: because of controlling planetary gears with oil hydraulic motor, can thoroughly divide power and load " from " or " closing ", also can make power and load be in " half-clutch ", realize carrying out within the specific limits stepless change, the friction clutcch that this device can replace present vehicle to use, make the clutch of vehicle realize electric control, and, can alleviate driver's labor intensity greatly like this without the gear shift of stepping on clutch pedal.This engaging and disengaging gear can replace the fluid coupling that uses in the present automatic transmission fully, and effectiveness of performance can improve greatly, thereby has great practical value.
