Description

A kind of clutch configuration that improves the vehicle start stationarity

Technical field

The utility model relates to a kind of car transmissions clutch configuration, and especially a kind of clutch configuration that can improve vehicle start stability belongs to engineering element or component technology field.

Background technique

Clutch is the parts that directly connect with motor in the car transmissions, and its active part links to each other with engine flywheel, and secondary part links to each other with one of speed changer.Clutch has the motor of making and engages gradually with transmission system, guarantees the function of gentle start, and friction clutcch is simple in structure with it, reliable performance, characteristics easy to maintenance are adopted by most automobiles.But in existing clutch configuration, platen contacts by smooth finish surface with friction plate, not only be subjected to the influence of each component axial runout in the system more serious, engine output torque is discontinuous when causing vehicle start, the starting jitter problem takes place, nor be beneficial to the transmission of Engine torque, cause the vehicle start time longer; The little chip of friction disc wear can't in time be discharged when clutch is worked in addition, makes slip resistance of clutch driven plate and speed changer become big, has aggravated starting and has shaken, brings problems such as engage a gear difficulty.

The model utility content

The purpose of this utility model is the drawback at prior art, and a kind of clutch configuration that can shorten start-up time, eliminate the raising vehicle start stationarity of vehicle start jitter phenomenon and the automatic dust discharge of feasible system is provided.

Problem described in the utility model realizes with following technical proposals:

A kind of clutch configuration that improves the vehicle start stationarity, it comprises release sleeve, release bearing, diaphragm spring, support ring, platen, one of speed changer, driven disc, friction plate and flywheel, described release sleeve, release bearing, diaphragm spring, platen, driven disc, friction plate and flywheel are assembled to the motor direction successively by speed changer, they are sleeved on the outside of one of speed changer, its specialization is: described platen rubbing surface is disc structure, platen rubbing surface and vertical plane angle α=and 0.1～0.2 °.

The clutch configuration of above-mentioned raising vehicle start stationarity, its specialization also is: described platen rubbing surface is the sawtooth rubbing surface, and described sawtooth is arranged in the donut mode.

The clutch configuration of above-mentioned raising vehicle start stationarity, its specialization also is: the inboard of described flywheel rubbing surface is provided with two dust exhausting holes, and described dust exhausting hole is the square opening structure of upper and lower end face decentraction.

The clutch configuration of above-mentioned raising vehicle start stationarity, described two dust exhausting holes are 180 ° of angles and arrange.

The utility model has increased the frictional force between platen and the friction plate by the platen rubbing surface of dish, serrated face structure, has not only shortened the time of vehicle start, and has solved the vehicle start jitter problem; The utility model is provided with the dust exhausting hole of special construction in the inboard of flywheel rubbing surface, utilize dust exhausting hole sidewall slope change to make the friction plate dust be discharged to the outside of clutch with air-flow, the air that enters by dust exhausting hole has been avoided the generation of cltuch slipping and ablation phenomenon simultaneously.In a word, the utility model is on original clutch basis, and the simple transformation through to its structure has promptly reached the shortening vehicle start time, eliminates the vehicle start jitter phenomenon, realizes the purpose of the automatic dust discharge of system, has significantly improved the stationarity of vehicle start.

Embodiment

Below in conjunction with specific embodiment the utility model is described:

Referring to Fig. 1, Fig. 2, Fig. 3, the utility model comprises release sleeve 1, release bearing 2, diaphragm spring 3, support ring 4, platen 5, one 6 of speed changer, driven disc 7, friction plate 8 and flywheel 9, described release sleeve 1, release bearing 2, diaphragm spring 3, platen 5, driven disc 7, friction plate 8 and flywheel 9 are assembled to the motor direction successively by speed changer, they are sleeved on the outside of one 6 of speed changer, described platen rubbing surface is disc structure, platen rubbing surface and vertical plane angle α=and 0.1～0.2 °; On the rubbing surface of platen 5, be provided with in the donut mode and arrange sawtooth 5-1 structure; The rubbing surface inboard of described flywheel 9 is provided with two dust exhausting hole 9-1, the square opening structure that described dust exhausting hole 9-1 is upper and lower end face decentraction, and two dust exhausting hole 9-1 are 180 ° of angles and arrange.

Referring to Fig. 2, vehicle is when starting, release bearing 2 of the present utility model drives release sleeve 1 and moves right, diaphragm spring 3 forms lever around support ring 4, diaphragm spring 3 fore-ends move right, the rear end is moved to the left, drive platen 5 and be moved to the left, because platen 5 rubbing surfaces are " dish ", so its outmost turns at first contacts with clutch friction plate 8, subsequently, the platen rubbing surface begins gradually to the inner ring contact, reaches whole rubbing surface contact at last, after output torque is greater than the vehicle start moment of torsion, vehicle becomes motion by static, realizes starting.

Referring to Fig. 3, Fig. 4, in the present embodiment, the platen rubbing surface is the sawtooth rubbing surface, width W=0.4mm of described sawtooth 5-1, depth H=0.08mm is when platen 5 rubbing surface contact friction sheets 8, friction factor increase because of surface of contact, make frictional force between the two become big, thereby make one 6 transmitting torque of speed changer faster, start-up time shortens.Simultaneously, because of platen 5 rubbing surfaces and friction plate 8 area of contact diminish, to flywheel end face run-out, friction plate end face run-out, the platen rubbing surface receptance variation of beating, vehicle start is more smooth and easy.

Referring to Fig. 5, Fig. 6, Fig. 7, being 180 degree angles at inboard two the dust exhausting hole 9-1 that are provided with of the rubbing surface of flywheel 9 arranges, in use, friction plate 8 progressively weares and teares, and the wearing and tearing back produces the dust-like chip, and this dust accumulation is in clutch and flywheel assembly, part enters driven disc spline and gearbox input shaft junction, make driven disc 7 difficulty of on one 6 of speed changer, sliding, thereby form the vehicle start jitter problem, have the engage a gear difficult problem simultaneously.Bring in behind motor, flywheel 9 is the clockwise direction rotation, so internal gas flow also is the clockwise direction rotation, the structure of dust exhausting hole 9-1 is that to enter a side at air-flow be the gentle slope, air-flow is rebuffed at opposite side subsequently, makes the dust in the air-flow realize separating, and is discharged to the outside of clutch.
