Technical field
The utility model belongs to machinery and control field, relates to a kind of automatic clutch device.This device can apply to common electrical motor-car, booster car, motorcycle.
Background technique
In existing common electrical motor-car, booster car, motorcycle, clutch has following three problems: at first, the disconnection of existing vehicular clutch and closure all need artificial control; If artificially control bad; When the motor output speed is higher than back transmission device rotating speed, easily gear etc. is caused greater impact, transmission efficiency is low; Damage vehicle drive system, also cause engine misses sometimes; Secondly, existing clutch is a normally off, and the vehicle sliding performance is very poor behind the door for pine tar; Once more, do not have electronic control system in the existing jaw clutch, it combines or closed keep left right tooth embedding speed difference and inertia combination, and this combination has impacts shortcomings such as big.Therefore, be badly in need of a kind of engaging and disengaging gear that is difficult for gear etc. is caused large impact automatically.
Summary of the invention
The utility model provides a kind of automation energy-conserving clutch, it can regulate the switching of clutch automatically, and clutch belongs to normally open in the utility model, and this makes that the vehicle sliding capability is good.
The utility model is through the rotating speed of real-time inspection vehicle wheel speed of tachogenerator and the chain drum that links to each other with the motor output terminal; And two rate signals are real-time transmitted to signal processing module; Signal processing module compares judgement to two speed in real time, and realizes the disconnection and the closure of jaw clutch through the control electromagnetic driver.
This engaging and disengaging gear comprises a pair of tachogenerator, magnet, signal processing module, notched teeth embedded-type clutch, rear propeller shaft, electromagnetic driver, thrust bearing.Wherein, rear propeller shaft right-hand member cylindrical has spiral chute; The notched teeth embedded-type clutch comprises tooth embedding A and tooth embedding B, and tooth embedding A is the structure of hollow annular, and tooth embedding B also is the structure of hollow annular, and inside has and the corresponding spiral chute of rear propeller shaft spiral chute;
Their annexation is:
A pair of tachogenerator; One of them is the wheel tachogenerator, is used to detect the rotating speed of wheel, and another is the motor tachogenerator; Be used to detect the rotating speed of the chain drum that links to each other with the motor output terminal, they be installed in respectively wheel with chain drum that the motor output terminal links to each other on.The signal of two tachogenerator outputs enters into signal processing module.Signal processing module is handled the signal of two tachogenerator outputs, give electromagnetic driver through signal processing computing output control signal, and signal processing module provides drive signal to electromagnetic driver.
The left side of band spiral fluted rear propeller shaft links to each other with gearbox or the engine output shaft on the car, and wheel hub is passed successively through radial bearing in the right side, and passes tooth embedding A, and tooth embedding A and wheel hub are connected as a single entity; Tooth embedding B links to each other with thrust bearing, electromagnetic driver successively; The spiral chute of the spiral chute of ring and rear propeller shaft is meshing in the tooth embedding B.
Wherein, described tachogenerator can be Hall transducer, photoelectricity test sensor etc.Described electromagnetic driver is meant after the energising can straight line motion one segment distance (at least 2 centimetres), the device that can set back fast after certain thrust (thrust of 30N at least), the outage is arranged, and it can be thrust electromagnet or the very high motor of rotating speed.
Working principle is: gearbox or engine output shaft on car provide power; Rear propeller shaft rotates; Rotate through the spiral chute band dynamic interlocking teeth B on the axle, spiral chute makes the rotation of rear propeller shaft can produce axial force to the left or to the right, with tooth embedding B to tooth embedding A compress or away from; And then be with dynamic interlocking teeth A, wheel hub rotation or both are independent of each other mutually, accomplish power transmission or do not carry out power transmission.
During concrete work; A pair of tachogenerator is gathered the rotating speed W1 and the rear wheel rotation speed W2 of motor in real time; The rate signal that two sensors will collect separately is transferred to signal processing module after through plastic filter circuit; Signal processing module compares W1 and W2, and electromagnetic driver is controlled.Before the startup, W1=0, W2=0.When starting, W2=0, and the W1 acceleration of will starting from scratch; Tachogenerator detects actuating signal and this signal is delivered to signal processing module, and signal processing module control electromagnetic push device makes the electromagnetic push device provide thrust left; Make the direction motion of tooth embedding B to tooth embedding A; And then the spiral fluted interaction of spiral chute through tooth embedding B and rear propeller shaft, make clutch seizure, at this moment the torque transfer of motor is to wheel; Wheel velocity consistent with chain drum speed (being W2=W1), the wheel accelerated service; When speed reaches necessarily, during the pine tar door, chain drum rotating speed W1 can reduce; Tachogenerator is gathered chain drum rotating speed W1 and vehicle wheel rotational speed W2; And two rate signals are transferred to signal processing module, signal processing module compares two speed, when chain drum W1 speed during less than vehicle wheel rotational speed W2; Signal processing module control electromagnetic push device makes the electromagnetic push device provide pulling force to the right; Make tooth embedding B to direction motion, and then interact, make clutch separately through the spiral chute of tooth embedding B and the spiral fluted of rear propeller shaft away from tooth embedding A; Vehicle gets into sliding state (clutch has reduced resistance of taxing greatly with wheel and transmission device or gearbox disconnection under this state).When vehicle quickened, chain drum accelerated at a high speed from low speed, the rotating speed of tachogenerator collection and contrast chain drum and wheel; When chain drum rotating speed identical with vehicle wheel rotational speed (W1=W2), signal processing module control electromagnetic push device makes the electromagnetic push device provide thrust left; Make the direction motion of tooth embedding B to tooth embedding A; And then the spiral fluted of spiral chute through tooth embedding B and rear propeller shaft interacts, and makes clutch seizure, the realization transmission.It is in order to reduce the impact of tooth embedding to wheel hub that clutch just combines when the chain drum rotating speed is identical with vehicle wheel rotational speed, also is the resistance that advances in order to reduce simultaneously.
Beneficial effect:
1, through clutch being broken off and closed control by the system of electric control; Make the left and right sides tooth of clutch be embedded in that rotating speed equates or close situation under combine; Thereby eliminated ordinary clutch closed impact that causes in movement process, effectively protected clutch mechanism parts and transmission shaft, prolonged the adaptation life-span; Reduced and impacted the capacity loss that causes, improved transmission efficiency to a certain extent.
2, this device belongs to normally disengaged clutch, only when acceleration needs, just combine, when pine tar behind the door, the clutch meeting is broken off, and helps sliding.This point has solved and has slided very poor defective after common dolly (like motorcycle, booster car etc.) is totally released throttle.
3, this device belongs to the automation clutch, need not artificial solenoidoperated cluthes, and the vehicle driver only needs to get final product according to self driving needs open out or pine tar door.It is improper and cause engine misses or bring to vehicle and strengthen the acceleration shock sense that this advantage has solved in the vehicle driving process artificial control clutch.
