Description
Technical field
The present invention relates to a kind of casing, particularly a kind of casing for bicycle booster.
Background technology
At present, bicycle has become the in the world most widely used vehicle with its economy, environmental protection, the advantage such as convenient, and technical personnel is also constantly making improvements.In the existing improvement project, important directions be exactly with in the process of riding because the Gravity changer that produces of jolting of the people's that rides attitude change or road is converted into moment, and by complicated step-up system, moment is offered bicycle middle shaft, for bicycle provides power-assisted.But the Regular Bicycle axis is installed in the five-way of vehicle frame, and narrow space can't hold complicated step-up system, so that these devices can only be exposed under the natural environment.
The utility model content
The purpose of this utility model provides a kind of casing, substitutes traditional bicycle bottom bracket, holds bicycle middle shaft and additional step-up system.
For achieving the above object, the utility model provides following technical scheme:
A kind of casing for bicycle booster comprises:
Front case;
Rear housing;
Quadrant;
Container cavity;
Described front case has relative bolt hole with described rear housing, the bolt of packing in the described bolt hole connects together described front case and limits described container cavity with described rear housing, described front case has one or more relative axis hole with described rear housing, and described quadrant is positioned at described front case or/and described rear housing upper end.
Selectively, also has knock hole on the described quadrant.
Selectively, has bearing seat in the axis hole of described front case and described rear housing.
Selectively, described front case and described rear housing have staggered flange.
Selectively, described quadrant and described front case and/or described rear housing are by casting integrated moulding.
Selectively, has bolt hole on the described quadrant.
The casing size is processing and fabricating as required, bicycle middle shaft and additional step-up system can be accommodated in the container cavity, and the axle of axis and additional step-up system can stretch out from axis hole, carries out separately function, casing is installed on the vehicle frame by quadrant, replaces traditional bicycle bottom bracket.
Further, owing to having bearing seat in the axis hole, be conducive to the rotation of each axle in the casing.
Further, because front case and rear housing have staggered flange, so that the container cavity leakproofness is better, be conducive to protect device wherein.
Further, quadrant and front case and/or rear housing casting, easy to process.
Further, have bolt hole on the quadrant, can be installed at an easy rate on the vehicle frame or pull down, be convenient to maintenance.
Description of drawings
Next in connection with accompanying drawing embodiment of the present utility model is explained in further detail, wherein:
Fig. 1 is the casing installation site schematic diagram of embodiment of the present utility model;
Fig. 2 is the casing front view of embodiment of the present utility model;
Fig. 3 is the section drawing of cutting open along the plane A-A among Fig. 2;
Fig. 4 is the partial enlarged drawing at the I place, position shown in Fig. 3.
Sequence number among the above figure: 1-casing 11-front case 12- bolt hole 13,14,15-axis hole 16-quadrant 17-bolt hole 18-knock hole 19-bearing seat 20-rear housing 21-container cavity 22-bicycle middle shaft 23-tween drive shaft 24-reinforcement axle.
The specific embodiment
With reference to figure 1, bicycle passes to bicycle middle shaft 22 by the complicated step-up system of a cover, for bicycle provides power-assisted again because the moment that Gravity changer produces passes to reinforcement axle 24.22 a whole set of step-up systems are encapsulated in the casing 1 from reinforcement axle 24 to bicycle middle shaft, and casing 1 is installed on the cycle frame, substitute traditional five-way.
Fig. 2 is the casing front view of embodiment of the present utility model, observes from front case 11 outsides.Have two bolts hole 12 on the front case 11, correspondingly, rear housing 20 has two relative bolts hole, and step-up system is packed into behind front case 11 or the rear housing 20, with bolt hole 12 interior inserting bolts, two housings is connected together form casing 1.Those of ordinary skills can imagine to have as required the bolt hole 12 more than two on front case 11 and the rear housing 20, make connection more firm.Have axis hole 13,14,15 on the front case 11, be used for each axle 22,23,24 shown in Fig. 3.Correspondingly, has relative axis hole on the rear housing 20.Those of ordinary skills can imagine should have at least an axis hole 15 on front case 11 and the rear housing 20, so that bicycle middle shaft 22 to be installed, also can as required, have a plurality of axis holes.In order to cooperate the installation of each axle, can have separately bearing seat 19 around each axis hole 13,14,15.The front case upper end has quadrant 16, has bolt hole 17 on the quadrant 16, is used for casing 1 is installed to cycle frame.Those of ordinary skills can understand, can there be bolt hole 17 in quadrant 16, and be installed on the vehicle frame by modes such as welding, but install by bolt, so that the dismounting of casing 1 is more convenient, therefore the maintenance of the step-up system of being convenient to wherein hold exists bolt hole 17 obviously to have more advantage.Also have knock hole 18 on the quadrant 16, wherein can insert locating dowel pin, so that front case 11, more convenient when rear housing 20 is assembled with step-up system.Those of ordinary skills can imagine at an easy rate, and quadrant 16 can either be positioned on the front case 11, also can be positioned on the rear housing 20, perhaps all has quadrant 16 on front case 11 and the rear housing 20.When all having quadrant 16 on front case 11 and the rear housing 20, the structure of front case 11 and rear housing 20 is roughly symmetrical.
Fig. 3 is the cutaway view of cutting open along the plane A-A among Fig. 2, has schematically shown simultaneously the step-up system that holds among the figure.Front case 11 with limited container cavity 21 after rear housing 20 connects together, from reinforcement axle 24, tween drive shaft 23 and bicycle middle shaft 22, and each element between them all is accommodated in wherein.
Fig. 4 is the partial enlarged drawing at the I place, position shown in Fig. 3.As seen from the figure, the connecting bridge between front case 11 and the rear housing 20 is interlaced flange, and after both connected, flange coincide mutually, has sealed well container cavity 21, has protected step-up system wherein.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only be subjected to the restriction of claims, those of ordinary skills can easily make amendment to it and change, but do not leave essence design of the present utility model and scope.
