Abstract
The utility model provides a dish wheel hub of stopping, includes that dish and dish stop wheel hub, dish and dish stop wheel hub are concentric, still include with above-mentioned dish and dish stop wheel hub concentric dish stop the gasket be equipped with decurrent claw suddenly on the dish stop the gasket, have the trompil that matches with claw suddenly on the dish, also be equipped with suddenly the piece on the wheel hub, suddenly on the wheel hub piece with the dish stop the gasket on the clearance match between the claw suddenly, the dish stop the trompil that the claw suddenly passed the dish of gasket, the dish stop wheel hub on suddenly the piece be located pass the dish trompil between the claw suddenly, dish stop gasket and dish fixed connection, the dish stop the gasket suddenly claw bottom and the dish stop wheel hub fixed connection, the dish trompil and dish stop the wheel hub suddenly and have the gap between the piece. The disc is not directly contacted with the disc brake hub, so that the friction between the disc and other parts is avoided, and the service life of the disc brake is relatively prolonged; the disc brake hub has strong capability of resisting brake torque; and the axial dimension is smaller, and the disc brake wheel hub can be adopted on the premise of not increasing the size of the front fork or the bottom fork.
Description
Technical field
The utility model relates to a kind of disc brake wheel hub.
Background technology
In general Electrical Bicycle, wheel hub is given in the electro-motor power transmission, and the disc that wheel hub is in contact with it connects, and disc is connected with screw with corresponding component on the wheel, realizes braking to wheel with this.
Above-mentioned disc is connected by screw with the direct plane contact of wheel hub, and area of contact is very little.Between glancing impact disc and wheel hub, produce very big moment of torsion, even disc is connected by screw with wheel hub, certain friction force is arranged, but all the time can some gap between screw and disc, difficulty overcomes bigger brake torque, so long-term use will be shortened the service life of disc greatly.In addition, above-mentioned disc brake wheel hub axial dimension is bigger.
The utility model content
Technical problem to be solved in the utility model provides a kind of braking and reliably reduces disc brake wheel hub axial dimension, and improves the disc brake wheel hub in service life.
In order to address the above problem, the utility model is taked following technical scheme:
A kind of disc brake wheel hub, the disc and the disc brake wheel hub that comprise arranged concentric, also comprise the ring-type disc brake pad concentric with it, downward prominent pawl circumferentially distributes in described disc brake pad upper edge, the perforate that matches with prominent pawl is arranged on the correspondence position of disc, the projection that the wheel hub upper edge circumferentially also is provided with, gap on projection on the wheel hub and the described disc brake pad between prominent pawl matches, the prominent pawl of disc brake pad passes the perforate of disc, projection on the disc brake wheel hub is inserted between the prominent pawl of the disc brake pad that passes the disc perforate, the disc brake pad is captiveed joint with disc, and captiveing joint with the disc brake wheel hub in the prominent pawl of disc brake pad bottom, has the slit between disc perforate and the disc brake wheel hub projection.
Prominent pawl on the described disc brake pad is the flute profile that is circular layout.
Prominent pawl and wheel hub projection on the described disc brake pad match.
The beneficial effects of the utility model are: the utility model has increased a disc brake pad, and disc contacts with the disc brake wheel hub by the disc brake pad, has avoided disc and disc brake wheel hub direct contact, has therefore avoided the friction of disc, has improved its service life relatively; The utility model has improved the reliability that the disc brake wheel hub bears brake torque; The utility model has shortened the axial dimension of disc brake wheel hub, opens under grade size prerequisite not increasing front fork or chain stay, adopts the disc brake wheel hub to become possibility.
Description of drawings
Fig. 1 is the structural representation of disc brake pad among the embodiment;
Fig. 2 is the structural representation of disc;
Fig. 3 is whole Unit Installation figure.
The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
With reference to Fig. 1-Fig. 3, a kind of disc brake wheel hub comprises disc 1 and disc brake wheel hub 2, the disc brake pad 3 that also comprises ring-type, be circumferentially with downward a plurality of prominent pawl 4 in described disc brake pad 3 upper edges, the perforate 5 that matches with prominent pawl 4 is arranged on the disc 1, wheel hub 2 upper edges circumferentially also are provided with a plurality of projections.During installation, the prominent pawl 4 of disc brake pad 3 passes the perforate 5 of disc 1, the gap of 4 of prominent pawls matches on projection on the disc brake wheel hub and the above-mentioned disc brake pad 3, projection on the disc brake wheel hub 2 is just between the gap of the projection 4 that passes from disc perforate 5, disc brake pad 3 and disc 1 are coupled together, captiveed joint with disc brake wheel hub 2 usefulness screws in disc brake pad 3 prominent pawl 4 bottoms again, screw 7 in the middle of promptly passing on the prominent pawl 4 connects, after the installation, the prominent pawl 4 of disc brake pad 3 is inserted down, projection on the disc brake wheel hub 2 is dashed forward up, sidewall by prominent pawl 4 and disc perforate contacts the resistance brake torque, such way of contact is better than plane contact mode of the prior art, it is strong to resist the brake torque ability, and the utility model disc passes through the prominent pawl of disc brake pad and the projection on the disc brake wheel hub contacts the moment of torsion of resisting the glancing impact generation, prevents disc and disc brake wheel hub direct contact, prevent the disc friction, prolonged the service life of disc relatively.In addition, the utility model disc brake wheel hub axial dimension is less.
Embodiment 2:
With reference to above-mentioned Fig. 1-Fig. 3, for the foregoing description, the boss that the prominent pawl 4 on the described disc brake pad 3 can be designed to be circular layout forms a plurality of equal-sized slot-shaped gap between the boss, the projection on the disc brake wheel hub 2 is exactly the flute profile projection that matches with above-mentioned slot-shaped gap.
Embodiment 3:
With reference to above-mentioned Fig. 1-Fig. 3, for above-mentioned two embodiment, the prominent pawl 4 on the described disc brake pad 3 matches with wheel hub 2 projections, and the area of contact of disc brake pad 3 and disc brake wheel hub 2 is big like this, can better resist brake torque.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
