Description
Technical field
The utility model relates to and the matching used centrifugal clutch of special car motor, assistant engine, transfer case and supplementary equipment.
Background technique
At present, the centrifugal clutch using on market, its centrifugal body is mainly by fan-shaped brake shoe and forming with the friction plate of steel plate, the centrifugal body subassembly of this structure, always gapped when fan-shaped brake shoe (centrifugal-block) and friction plate laminating, after tensioned, friction plate part is in stress and deformation state, causes friction plate stressed unstable in the time of work, and then causes that the abnormal or friction material of friction disc wear peels off; If clutch in high speed operation state, also easily causes assembly dynamic balance accuracy grade, decline produces the situations such as vibrations, abnormal sound, has a strong impact on bearing capacity and the working life of clutch.
If guarantee to approach between fan-shaped brake shoe and friction plate seamless applying from technique, its cost is quite high, also do not have at present available ripe and have the technique of cost performance.
Summary of the invention
The first problem that the utility model solves: always gapped while solving existing centrifugal clutch centrifugal-block and friction plate laminating; after tensioned, friction plate part is in stress and deformation state; rotating speed and theoretical rotational speed that when work, centrifugal body engages completely with driven member have deviation; the low generation vibrations of centrifugal body dynamic balance accuracy level down, abnormal sound; and friction plate is because of problems such as point or line contact cause that the abnormal or friction material of wearing and tearing is peeled off, improves the performance and used life of clutch.
The Second Problem that the utility model solves: reduced manufacture cost.
In order to solve above two problems, the utility model proposes the centrifugal clutch of the centrifugal body of integrated type, multiple centrifugal-blocks are contained in the scalloped recess of input shaft, by spring, the two ends of centrifugal-block are strained, and the baffle plate that centrifugal-block bi-side are installed on input shaft boss is fixed; Forward flange and rear flange are arranged on respectively input shaft front end and back end by rolling bearing, forward flange and rear flange are fixed on the front/rear end of driven disc by self seam, and by bolton, it is characterized in that: friction plate is directly fixed on centrifugal-block, form an entirety with centrifugal-block.
Working principle: in the time that input shaft accelerates rotation, due to the effect of centrifugal force, centrifugal body overcomes spring force and radially throws away, and contacts with driven disc inwall, finally makes input shaft and driven disc synchronous rotary; When needs centrifugal clutch separates while not working, reduce input speed, fan-shaped brake shoe is return under link spring action, friction plate is separated with belt wheel inwall and completes the separating action of clutch.
Beneficial effect: compared with existing centrifugal clutch, the integration of centrifugal-block and friction plate, effectively avoid cooperation cambered surface between centrifugal-block, friction plate (being fixed on the Steel Spring Plate) deviation in the generation of the aspects such as processing and assembling, effectively reduced friction plate and engage with clutch belt wheel inwall the problem on deformation of bad generation; After centrifugal-block and friction plate integration, can make friction plate can realize completely first cambered surface of friction plate and the complete combination of belt wheel inwall in the time engaging, thereby the area of contact that simultaneously increased the coating performance that improved friction plate and belt wheel inwall has improved friction material stressed uniformity everywhere greatly, make clutch can approach theoretical value transmitting torque, vibrations while having reduced clutch work, have improved stable working, functional reliability and Acceptable life.

Embodiment
As Fig. 1, shown in 2, further describe the utility model as follows: the centrifugal clutch of the centrifugal body of integrated type, a pair of centrifugal-block 1 is contained in the scalloped recess of input shaft 4, by spring 2, the two ends of centrifugal-block 1 are strained, the baffle plate 5 use screws 6 that centrifugal-block 1 bi-side are installed on input shaft boss are fixed, prevent that fan-shaped brake shoe 1 from sliding axially, in the time that centrifugal-block 1 accelerates to rotate together with input shaft 4, due to the effect of centrifugal force, two fan-shaped brake shoes 1 overcome the effect of spring force 2, radially throw away, when approaching working speed, centrifugal-block 1 and driven disc 9 inwalls complete synchronizes combination.Forward flange 7 and rear flange 8 are arranged on respectively input shaft 4 front end and back end by rolling bearing 3, and forward flange 7 and rear flange 8 are fixed on the front/rear end of driven disc 9 by self seam, and use respectively bolt 10 fastening; Friction plate 1a is directly fixed on centrifugal-block, forms an entirety with centrifugal-block 1.
The structure such as input shaft 4 use keys, interference fit and the line shaft of the centrifugal clutch of the centrifugal body of integrated type connect, rotated by line shaft band driven input shaft 4 and centrifugal-block 1, in the time of the line shaft slow-speed of revolution, the centrifugal force of centrifugal-block 1 is less than the pulling force of spring 2, centrifugal-block 1 can not move radially, and clutch is in separated state.When needs clutch in conjunction with time, when increasing line shaft rotating speed and making theory that the rotating speed of input shaft 4 approaches clutch in conjunction with rotating speed, the centrifugal force of centrifugal-block 1 is greater than the pulling force of spring, there is thus outside radial displacement, centrifugal-block 1 is synchronizeed combination with the inwall of driven disc 9, drive driven disc synchronously to rotate, realize the combination of clutch.In the time of needs clutch separation, reduce gradually line shaft rotating speed, the rotating speed that makes input shaft 4 is lower than theory in conjunction with rotating speed, and the centrifugal force of centrifugal-block 1 is less than the pulling force of spring 2, thus centrifugal-block 1 produces the inside reset that moves radially, and realizes the separating action of clutch.
As shown in Figure 3, friction plate 1a is by screw or be bolted on centrifugal-block.
As shown in Figure 4, friction plate 1a is adhesively fixed on centrifugal-block.
Friction plate 1a is fixed on the structure of centrifugal-block, does not limit to the mode shown in Fig. 3, Fig. 4, can be also: friction material layer solidifies, rising the mode such as connects.
Centrifugal-block 1 can be one, two or multiple.
Driven disc 9 can be belt pulley, can be also any inner chamber can with centrifugal-block can outputting power in conjunction with outside component.
For above-mentioned mapped structure, can be in its transformation range independent assortment, consequent mode of execution is apparent within the scope of the claim of the utility model scheme.
