Abstract
The one-way clutch for the automobile drive of the utility model, belonging to the vehicle clutch technique, is composed of a flywheel and a clutch cover installed on the crankshaft, a supporting frame, a releasing lever, a pressure plate, a friction driven plate installed between the flywheel and the pressure plate, a driven shaft, a coiled spring installed between the clutch cover and the pressure plate, a releasing sleeve barrel and a releasing bearing loose sheathed on the shaft sleeve of the driven shaft, a returning spring installed between the releasing sleeve barrel and the machine body and a clutching control mechanism attached on the end surface of the releasing sleeve. Friction plates are arranged on the periphery of the friction driven plate, and a one-way clutch whose center provided with splined holes is installed in the inner side thereof. The one-way clutch, whose 3-24sets roller mechanisms are uniformly distributed, can be a roller type as well as a pawl type. The utility model can slide automatically in gear and can be directly geared out of gear. The utility model has the advantages of reliable and safe parking, convenient and flexible operation and good fuel-saving effect, and can be used to the hand-shift vehicles, in particular to the vehicles such as taxies, buses, etc.
Description
Technical field
The utility model belongs to the automobile clutch technical field, more particularly relates to the improvement of vehicle transmission overrunning clutch.
Background technique
Automobile clutch is between motor and speed changer, and direct and motor interrelates.Extensively adopt friction clutch in the automobile machinery power train.Friction clutch has more detailed explanation from, the elemental motion principle of closing in " automobile chassis structure and maintenance " that the Electronic Industry Press publishes in September, 2002.
Easy to use, advantages such as oil-saving effect good, long service life, protection speed changer that the vehicle transmission overrunning clutch has.Therefore, installing overrunning clutch additional on automobile, is one of many technician problem that will solve.The transmission system of existing bicycle and modern motorcycle does not have reverse gear, and unidirectional transmission clutch (sliding) device can be assembled in any position of its transmission system.But present automobile mostly is provided with reverse gear, and the difficulty of assembling unidirectional transmission clutch (sliding) device is just very big.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, with the motor vehicle friction clutch repacking, installs overrunning clutch additional between its friction plate and clutch shaft, to satisfy the needs of automobile slide and driving.
In order to achieve the above object, the utility model comprises flywheel and the clutch cover on the bent axle that is installed in motor, be installed in the support on the clutch cover, rack-mount separator levers, be hinged on the platen of separator levers end, be installed in the friction driven disc between flywheel and the platen, be installed in the splined hole of friction driven disc and the driven shaft in the central hole of the crankshaft, be installed in the helical spring that is uniformly distributed along the circumference between clutch cover and the platen, pine is enclosed within release sleeve and the release bearing on the axle sleeve of driven shaft, be installed in the Returnning spring between release sleeve and body and be resisted against on-off control mechanism on the release sleeve end face etc.Friction driven disc periphery is a friction plate, and overrunning clutch is installed in it, and the center of overrunning clutch has the splined hole on the spline that can be sleeved on driven shaft.The performance that overrunning clutch makes the friction driven disc have unidirectional drive, oppositely dally and slide.And then when making automobile on clutch, had the unidirectional drive transferring power, motor is in the function that idling is slided oppositely the time.If the rotating speed of overrunning clutch outer ring (together with friction plate) is the rotating speed of V1, overrunning clutch inner ring is V2, then when V1=V2, motor is in the driving operating mode; When V2＞V1, automobile slide.
The utility model is identical with prior art from, the elemental motion principle of closing.
Overrunning clutch can be a roller type, and its roller bearing mechanism is that 3～24 covers are uniform.Roller type mono-directional overrun clutch reliable operation, simple in structure, long service life.3～24 covers uniformly can make its load equalization, reduce the load of each roller bearing, prolong its working life.3～24 cover roller bearings can a shared roller bearing frame.The roller bearing frame can make 3～24 cover roller bearing accurate positionings, the load equilibrium, and synchronism is good, and further prolongs its working life.
Overrunning clutch also can be a pawl type.The pawl type mono-directional overrun clutch uses in bicycle in a large number.Therefore, its mature production technology, cost of production is also more cheap.
The friction driven disc also can adopt the overrunning clutch of other type.
Task of the present utility model comes to this and finishes.
The utility model unidirectional drive transferring power, the advantage that motor is in the idling sliding capability oppositely the time are:
1. after the engine start, can shift up as long as lift the throttle not stepping on clutch, until the most high-grade; After lifting throttle, can slide automatically at shelves; During downshift,, can directly perform as long as rotating speed of speed changer is higher than bent axle.The operation light and flexible, easy to use.
2. when sliding after automobile quickens, motor is in idling operation, and oil-saving effect is good.
3. go up a slope when stopping, can add the low-grade lock car that advances; Descending is then locked car with reverse gear when stopping, reliable, the safety of stopping, convenience.
4. both can prolong the working life of clutch, can protect speed changer again.
The utility model is applicable to all manual automobile, especially taxis, bus.
