Description
Technical field
The utility model relates to a kind of clutch, especially relates to a kind of manually-scrubbing type clutch with positioning supports.
Background technique
In the housing of clutch generally between motor and gearbox, the engine power of dynamic power machine can be passed in rotating shaft in the mode of switch by clutch.Friction clutch applies the most also be a history class clutch at most in clutch, and manually-scrubbing type clutch is exactly a kind of typical friction clutch.The manually-scrubbing type clutch being positioned at housing comprises parking brake, brake disc, brake strap and axle core.The brake disc being positioned at housing can rotate along axle core, and brake strap circularizes to be embraced around brake disc.Control to hold tightly between brake strap and brake disc and unclamp by parking brake, the braking of brake disc can be realized.
Brake strap activity space in housing of existing manually-scrubbing type clutch is larger.When brake strap is opened, there is the problem that gap is uneven, easily produce and wipe band.For this problem, traditional way is all by controlling brake strap rigidity and the control of production process tune band.But the control effects that this way obtains is poor, batch production difficult quality guarantee.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of manually-scrubbing type clutch with positioning supports, effectively can improve the uneven phenomenon in brake strap gap, and reduce vibrating noise.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of manually-scrubbing type clutch with positioning supports, comprise parking brake, brake disc, brake strap and axle core, described parking brake is connected with brake strap, described axle core is positioned at the center of ring-shaped brake dish, brake disc rotates round axle core, described brake strap to be looped around around brake disc ringwise, the supporting post that multiple flexible material is made is provided with in the periphery of brake strap, described multiple supporting posts be spaced and annular distribution in the periphery of brake disc, predetermined spacing is there is between described supporting post and brake disc,
Press down parking brake, parking brake drives brake strap to move, and brake disc is held tightly by the periphery that brake strap is close to brake disc, unclamps parking brake, and brake strap leans on the support columns after leaving brake disc, and supporting post forms fulcrum to brake strap.
Also comprise housing, described parking brake is fixed on housing, and described housing is provided with a circular groove, described axle core is positioned at the central position of groove, is enclosed within outside axle core outside described brake disc, and brake disc can rotate along axle core in housing.Housing all serves certain protective action to the axle core fixed within it, brake disc, brake strap.
Described brake strap one end is fixedly connected with described housing, the other end of brake strap is connected with parking brake, and parking brake presses down and drives brake strap to move to parking brake direction, is close to the periphery of brake disc after brake strap is tightened up, unclamp parking brake, brake strap restores to the original state and leans on the support columns.Brake strap one end is fixed, and one end is controlled by parking brake.
Described supporting post is fixed on the cell wall of described groove.Supporting post be arranged so that the sphere of activities of brake strap is limited, reduce the vibrations of brake strap to a certain extent.
Described supporting post is quality of rubber materials.Rubber is a kind of flexible material, and the supporting post of quality of rubber materials has good effect to shock-absorbing.
The periphery of described brake strap is provided with three supporting posts, and three described supporting posts comprise the first supporting post, the second supporting post and the 3rd supporting post.The periphery of brake strap arranges three supporting posts and can form support to brake strap preferably.
The first described supporting post is positioned on the obverse cell wall of parking brake, the second described supporting post and the 3rd supporting post lay respectively at the both sides of the first supporting post, the second described supporting post and the 3rd supporting post lay respectively on two corresponding surfaces of groove cell wall, and the second described supporting post, the 3rd supporting post are equal to the distance of the first supporting post.Arrange the position of three supporting posts like this, support effect is better.
Compared with prior art, the utility model has the advantage of that the peripheral ring of brake disc is around brake strap, and the periphery annular spread of brake strap there is multiple supporting post.The activity space being arranged so that brake strap of supporting post reduces, and can reduce vibrating noise, and effectively can improve the uneven phenomenon in brake strap gap, reduces the wiping band caused because gap is uneven bad.Supporting post is made up of flexible material, when brake strap is against supporting post, can reduce the vibrations of brake strap.

Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1 to Figure 3: a kind of manually-scrubbing type clutch with positioning supports, comprise parking brake 1, brake disc 2, brake strap 3 and axle core 4, parking brake 1 is connected with brake strap 3, axle core 4 is positioned at the center of ring-shaped brake dish 2, brake disc 2 rotates round axle core 4, brake strap 3 to be looped around around brake disc 2 ringwise, the supporting post 5 that multiple flexible material is made is provided with in the periphery of brake strap 3, multiple supporting post 5 is spaced also annular distribution and, in the periphery of brake disc 2, there is predetermined spacing between supporting post 5 and brake disc 2; Press down parking brake 1, parking brake 1 drives brake strap 3 to move, and brake disc 2 is held tightly by the periphery that brake strap 3 is close to brake disc 2, unclamps parking brake 1, and brake strap 3 leans against after leaving brake disc 2 on supporting post 5, and supporting post 5 pairs of brake straps 3 form fulcrum.Also comprise housing 6, parking brake 1 is fixed on housing 6, and housing 6 is provided with a circular groove 7, axle core 4 is positioned at the central position of groove 7, is enclosed within outside axle core 4 outside brake disc 2, and brake disc 2 can rotate along axle core 4 in housing 6.
Brake strap 3 one end is fixedly connected with housing 6, the other end of brake strap 3 is connected with parking brake 1, and parking brake 1 presses down and drives brake strap 3 to move to parking brake 1 direction, is close to the periphery of brake disc 2 after brake strap 3 is tightened up, unclamp parking brake 1, brake strap 3 restores to the original state and leans against on supporting post 5.
