Abstract
The utility model relates to a compact automobile engine flywheel assembly and solves the problem that the diameter of a flywheel is required to be correspondingly increased when a large clutch is installed. The compact automobile engine flywheel assembly comprises a flywheel body and a flywheel ring gear which is fixedly integrated on the outer ring of the flywheel body. After improvement is made, clutch installation bosses are evenly distributed on the flywheel body, the clutch installation bosses are arranged on the edge of the installation end surface of the clutch friction plate of the flywheel body, and clutch installation holes are arranged on the clutch installation bosses. The utility model breaks a conventional design pattern that the diameter of the flywheel is required to be matched with the radial dimension of the clutch. By arranging the axially convex clutch installation bosses on the flywheel body, the design can satisfy the need of the installation of the small pressure plate of the clutch. By using the axial bosses for replacing the increase of the radial dimension, the circumferential dimension of the entire engine can be reduced and the assembling requirement of matching a small flywheel with the large clutch can be satisfied. The utility model has the advantages that the occupied area is small, the weight is light, the structure is compact, the economy of engines with the same performance is increased and the like.
Description
Technical field
The utility model relates to a kind of automobile component, and the motor car engine fly wheel assembly of little, the light weight of particularly taking up room, compact structure belongs to technical field of automobile engine.
Background technique
Fly wheel assembly is the discoid part that motor is contained in crankshaft rear end, and its function can couple together motor and speed changer, and it has bigger rotary inertia, can make motor smooth starting and rotation, is the vitals of engine balance, starting and transmission.Fly wheel assembly comprises the flywheel body and is set in the gear ring of flywheel body wheel rim that the actuation gear engagement of gear ring and actuating motor is for piloting engine usefulness.The clutch of automobile also is contained on the flywheel, utilizes the rubbing surface of flywheel ear end face as actuator, is used for external transferring power.Flywheel rim is provided with groove or the pin-and-hole with marking, and for the usefulness of determining the engine compresses top dead center, also integrated signal teeth reads signal for speed probe on the flywheel.Usually for different automobile types, the size of fly wheel assembly is also inequality, and is single from satisfying the angle of installation requirement, changes the installation that flywheel diameter can adapt to multi-form clutch.But for the clutch of large-size, increase flywheel diameter simply, can make motor complete machine size become big undoubtedly, the motor related components is as cylinder body, the size of transmission case also needs corresponding adjustment to increase, can make the too fat to move heaviness of engine structure like this, the Economy of motor is affected.
The model utility content
The utility model is used to solve the defective of above-mentioned prior art and provides a kind of and do not increase the flywheel circumferential size and can satisfy the motor car engine fly wheel assembly of the compact structure of big clutch friction plate installation requirement.
The alleged problem of the utility model solves by the following technical programs:
A kind of motor car engine fly wheel assembly of compact structure, comprise the flywheel body in the formation and be combined in the flywheel ring gear of flywheel body outer ring admittedly, flywheel body periphery is provided with signal teeth, its specialization is: uniform clutch installation base on the described flywheel body, described clutch installation base is positioned at the edge that flywheel body clutch friction plate is installed end face, and described clutch installation base is provided with the clutch mounting hole.
The motor car engine fly wheel assembly of said structure compactness, described clutch installation base is three, described signal teeth extends to clutch installation base periphery.
The motor car engine fly wheel assembly of said structure compactness, the degree size H that described clutch installation base is high is 5-20mm.
The utility model needs the problem of corresponding increase flywheel diameter at the large scale clutch is installed, designed a kind of motor car engine fly wheel assembly of compact structure, this fly wheel assembly is broken the conventional design pattern that flywheel diameter need mate the clutch radial dimension, in order to satisfy the installation of clutch friction plate and clutch compressing disc, axial raised clutch installation base is set on the flywheel body, this boss is provided with the clutch mounting hole site, and signal teeth is extended to the boss outer surface.The design of the utility model clutch installation base can be satisfied the installation needs of the little platen of clutch, with the increase of axial boss replacement circumferential size, can reduce the circumferential size of complete machine, satisfies the matching requirements that the small size flywheel cooperates the large scale clutch.The utlity model has little, the light weight of taking up room, compact structure, can make complete machine structure size and performance the best, increased characteristics such as Economy with the performance motor.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the boss partial enlarged view.
Label is as follows in the accompanying drawing: 1. flywheel body, 1-1. signal teeth, 1-2. clutch friction plate attachment face, 2. flywheel ring gear, 3. clutch installation base, 3-1. clutch mounting hole, 4. flywheel mounting hole.
Embodiment
Referring to Fig. 1, comprise flywheel body 1 during the utility model constitutes and be combined in the flywheel ring gear 2 of flywheel body outer ring admittedly, be provided with signal teeth 1-1 in flywheel body periphery.For under the condition that does not increase the flywheel diameter size, satisfying the requirement that the large-size clutch is installed, the utility model is set up clutch installation base 3 on the flywheel body, the clutch installation base is distributed on the end face of flywheel body away from the flywheel ring gear side, be the edge that clutch friction plate is installed end face 1-2, the clutch installation base is provided with clutch mounting hole 3-1.This design is mainly used in the clutch friction plate flywheel bigger with respect to clutch compressing disc, though the boss of setting up has increased the axial dimension of flywheel, but reduced flywheel mass in fact comparatively speaking, because if the clutch friction plate of size of the same race is installed, the tradition flywheel need strengthen on diameter dimension, flywheel mass obviously increases thereupon, and the design of boss is under the situation that does not reduce flywheel intensity, quality and rotary inertia influence to flywheel are little, can reduce the circumferential size of complete machine, simultaneously also reduce the complete machine cost, and satisfied the requirement of rotary inertia.
Referring to Fig. 1, Fig. 2, signal teeth 1-1 extends to clutch installation base periphery, satisfy obtain signal in, also can increase the reliability of clutch mounting hole site.The effect that can play stiffening rib is said in nature from stressed in the extension of signal teeth, improves the requirement of strength of clutch mounting hole on the boss, and also is easier on processing technology realize.Clutch installation base 3 high degree size H are 5-20mm.
When the utility model uses, by flywheel mounting hole 4 it is assemblied in connecing on the dish of crankshaft rear end, with bent axle run-in synchronism, and gearbox is passed in the power of motor output by the clutch that is installed on the flywheel, Starter driving gear and flywheel ring gear engagement drive flywheel crankshaft and rotate, with engine ignition, speed probe is gathered signal on signal teeth, the time of ignition of automatically controlled engine.
