Abstract
The utility model discloses an E-scooter brake mounting structure which comprises a brake and a flat fork. The brake is fixed on the flat fork. The E-scooter brake mounting structure is characterized in that a stop groove, the flat fork is provided with a stop block matching with the stop groove, the brake is fixed on the flat fork through a hub shaft, and the stop groove and the stop block coordinate to position the brake. The E-scooter brake mounting structure can be mounted to quickly and accurately position the brake by inserting the stop block of the flat fork into the stop groove of the brake, and the brake is quickly fixed to the flat fork by allowing the hub shaft of the brake to penetrate through the mounting structure. The E-scooter brake mounting structure is simple in structure and allows for fast and accurate positioning and mounting of the brake, mounting efficiency and quality of the brake are improved, and side force is avoided. Anomalies of the brake such as brake block grinding and noise are avoided.
Description
Technical field
The utility model relates to a kind of battery-driven car, particularly relates to a kind of mounting structure of battery-driven car drg.
Background technology
In existing elec. vehicle, the support that will be used for supporting wheel hub in vehicle is referred to as chain stay, will be referred to as for the mechanism that wheel hub is braked: drg; And dual mode is adopted in the installation of the battery-driven car drg on the existing market basically, 1, battery-driven car drg mounting means; 2, electric motorcycle vehicle brake mounting means.Its something in common is exactly that drg and chain stay location fixedly is bolt and fixes; These two kinds of mounting structures have following defective:
1) the drg efficiency of assembling is low, and after the battery-driven car drg was installed on the chain stay, the spline of drg need to fix by dowel bolt; After the electric motorcycle vehicle brake is installed on the chain stay, at first will keysets be installed at chain stay, keysets be connected with drg again, install loaded down with trivial detailsly, and efficient is low, has also increased material and cost of labor.
2) problem that produces: the bad phenomenon such as lock, abnormal sound in use appear grinding in drg, this is because in the drg installation process, at bolt drg is produced side force so that the location is offset in the fixing urgent process, drg is drawn the askew problem that causes.
Summary of the invention
The utility model purpose provides a kind of battery-driven car drg mounting structure, has accurate positioning, Fast Installation and to the mounting structure of drg without side force.
The utility model adopts following technical scheme for achieving the above object:
A kind of battery-driven car drg mounting structure comprises drg and chain stay, and described drg is fixed on the described chain stay, it is characterized in that: be provided with the spline groove on the described drg, be provided with anti-rotation block with matching on the described chain stay; Described drg is fixed on the chain stay by hub spindle, and described anti-rotation block is stuck in to match in the spline groove drg is positioned.This structure is because after having cancelled connecting panel and having used screw that drg is positioned, reach accurate positioning, install fast and reduced the skew that drg occurs when mounted, so that drg on axle without the generation of side force, finally reduced the bad phenomenon such as mill lock.
Further, described spline groove be shaped as the flat degree of lip-rounding, anti-rotation block is arranged to cylindrically match with the spline groove.The anti-rotation block of this kind shape is made simple, and is convenient, drg carried out spacing, prevents the drg rotation.
Further, described anti-rotation block is arranged to flats, and the drg spline groove that matches with anti-rotation block then is arranged as flat nick shaped.This design is so that the parts that match become face to cooperate, so that cooperate locating effect better.
Further, described drg is the aluminum alloy integral type, and the spline groove is arranged in beyond the lock shell diameter, is convenient to installation and stressed effect good.
Further, the groove depth of described spline groove is not less than 20mm, and part easy to use need to be regulated the needs of wheel hub front and back position.
Further, described drg is rear brake, and described spline groove is arranged on the front end of rear brake, and described anti-rotation block is installed in the inboard of chain stay, and the position of the more convenient layout spline of this kind design groove also meets the design custom.
Beneficial effect
The utility model structure only need to snap in the spline groove of drg the anti-rotation block on the chain stay when mounted, and positioning stop passes the hub spindle of drg drg is fixed fast and quick and precisely is positioned on the chain stay fast and accurately.The utility model is simple in structure, can realize the fast and accurately location and installation of drg, has improved efficient that drg installs and the installation quality of drg, and produces without side force, has avoided the bad phenomenon such as mill lock, abnormal sound of drg.
Description of drawings
Fig. 1 is the utility model chain stay front elevation;
Fig. 2 is the utility model brake structural schematic diagram;
Fig. 3 is that drg cooperates schematic diagram with chain stay in the utility model.
The specific embodiment
A kind of battery-driven car drg mounting structure, comprise as shown in Figure 1 the chain stay that is installed in the battery-driven car rear end 1 and the drg that is installed in hub side 2 as shown in Figure 2, described drg 2 is fixed on the described chain stay 1, the front end of described drg 2 is provided with spline groove 4, is provided with anti-rotation block 3 with matching on the described rear chain stay 1; Described drg 2 is fixed on the chain stay by the wheel hub rotating shaft, and the other end is located fast by spline groove 4 and anti-rotation block 3.
In the present embodiment, described spline groove be shaped as the flat degree of lip-rounding, anti-rotation block is arranged to cylindrically match with the spline groove, anti-rotation block is that columniform figure does not draw.
In the present embodiment, described anti-rotation block is arranged to flats, and the spline groove of the drg that matches with anti-rotation block then is designed to flat nick shaped.
In the present embodiment, the groove depth of described spline groove is not less than 20mm, and the needs that part easy to use like this need to be regulated the wheel hub front and back position are finely tuned, and guarantees the conformability of assembling.
For the shape of spline groove and anti-rotation block, can be various shape, all be fine as long as meet the structure that is used for limiting its rotation between cooperating between drg and the chain stay, here just do not exemplify one by one.
In the present embodiment, described drg is arranged as the aluminum alloy integral type, and the spline groove is opened in the lock shell diameter outside.More be conducive to arrange notch position and be convenient to install and stressed effect good.
The preferential embodiment of the present embodiment is that described drg is rear brake, and described spline groove is arranged on the front end of rear brake, and described anti-rotation block is installed in the inboard of chain stay.
Fig. 3 is the drg of the present embodiment and the assembly structure figure of chain stay, has demonstrated fully drg and chain stay by simple design, reaches always open question for a long time of solution.
The front end that the utility model is mentioned is for the travel direction of battery-driven car.
When mounted, the spline groove 4 of drg 2 is snapped in anti-rotation block 3 on the chain stay 1, just positioning stop 2 fast and accurately is fixed on drg 2 on the chain stay 1 fast by the rotating shaft of fixedly passing anti-rotation block 2.The utility model is simple in structure, can realize the fast and accurately location and installation of drg, has improved efficient that drg installs and the installation quality of drg, without side force, avoids the bad phenomenon such as mill lock, abnormal sound of drg.
