Abstract
The utility model discloses a limit structure of steel bowl and lower gear under motor-assisted vehicle, its structure comprises steel bowl, lower bearing and lower gear down, lower steel bowl include tube head, bearing frame and step, have lower bearing in the steel bowl down, have lower gear down under the lower bearing, its characterized in that has 1S N lug on the step of the lower steel bowl with preceding fork truck head pipe contact, has 2 lugs down outside the plane of the bearing frame mouth of steel bowl down, the chassis outer edge of lower gear have 2 protruding shelves pieces, protruding shelves piece and the lower lug of lower steel bowl of lower gear are at the coplanar, beneficial effect is: the convex block of the lower steel bowl is positioned on the same plane with the convex block of the lower gear, so that the rotating direction of the front wheel can be limited within a certain rotating angle range; because the lower steel bowl is low in height, the material consumption can be reduced, and the material consumption cost can be saved.
Description
Technical Field
The utility model relates to a power-assisted vehicle structure especially relates to a limit structure of steel bowl and lower gear under power-assisted vehicle.
Background
The moped becomes a more and more popular daily vehicle at present, mops with various functions are continuously available, a manufacturer proposes to develop a new product, and hopes to develop the moped with a limited headstock rotation angle.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a limit structure of steel bowl and lower gear under the power-assisted vehicle, reform transform the lower steel bowl of the steel bowl subassembly under the preceding fork truck head pipe and the structural configuration of lower gear, the steel bowl sets up spacing lug under, and it is spacing to realize the turned angle of preceding wheel direction.
In order to solve the technical problem, the utility model adopts the following scheme: a limit structure of a lower steel bowl and a lower gear of a power-assisted vehicle is structurally composed of the lower steel bowl, a lower bearing and the lower gear, wherein the lower steel bowl comprises a tube head, a bearing seat and a step, the lower bearing is arranged in the lower steel bowl, and the lower gear is arranged below the lower bearing.
The positions of the 1-N upper convex blocks are equally divided when the number of the upper convex blocks is more than 1, the upper convex blocks are square in shape and same in size, and the upper convex blocks correspond to the notches of the front forklift head pipe.
The 2 lower convex blocks are mutually and symmetrically positioned at 180 degrees.
The 2 convex stop sheets are mutually positioned in 180 degrees symmetry.
Because the lower convex block and the convex baffle are in the same plane, the function of limiting the rotating direction of the front wheel within a certain rotating angle range is achieved.
The height of the lower steel bowl is lower than that of a normal lower steel bowl by the thickness of the lower chassis, so that the height of the lower steel bowl is low, the material consumption is reduced, and the material consumption cost can be saved.
The utility model discloses a limit structure's of steel bowl and lower gear under moped beneficial effect is: the convex baffle and the lower convex block are in the same plane, so that the rotating direction of the front wheel can be limited within a certain rotating angle range; due to the fact that the lower steel bowl is low in height, materials are reduced, and material cost can be saved.
Drawings
Fig. 1 is an exploded view of the structure of a lower steel bowl and a lower gear limit structure of a moped.
Fig. 2 is a schematic diagram of a lower steel bowl of a moped and a lower steel bowl of a limiting structure of a lower gear (compared with the first diagram) turning 90 degrees.
Detailed Description
For ease of illustration, the invention is described in detail with reference to one embodiment and the accompanying drawings as follows:
as shown in fig. 1 and 2, the structure of the limit structure of the lower steel bowl and the lower gear of the power-assisted vehicle comprises the lower steel bowl 1, a lower bearing 2 and a lower gear 3, wherein the lower steel bowl 1 is internally provided with the lower bearing 2, the lower gear 3 is arranged below the lower bearing 2, and the lower steel bowl 1 comprises a pipe head, a bearing seat and steps and is characterized in that the steps of the lower steel bowl 1 contacted with a front forklift head pipe are provided with 2 upper convex blocks 1.1, the plane of the bearing seat opening of the lower steel bowl 1 is provided with 2 lower convex blocks 1.2, and the outer edge of a chassis of the lower gear 3 is provided with 2 convex pieces 3.1.
The lower steel bowl 1 is provided with 2 upper convex blocks 1.1, the mutual positions are 180 degrees and symmetrical, the shapes are square, the sizes are 5mm, and the upper convex blocks correspond to the notches of the head pipe of the front forklift.
The 2 lower convex blocks 1.2 are mutually and symmetrically positioned at 180 degrees.
The 2 convex baffles 3.1 are mutually positioned at 180 degrees and symmetrical.
The upper convex block 1.1 and the lower convex block 1.2 can not be overlapped in the vertical direction.
The lower convex block 1.2 and the convex baffle 3.1 are in the same plane and have the function of limiting the rotation direction of the front wheel within a certain rotation angle range.
The height of the lower steel bowl 1 is lower than that of the normal lower steel bowl by the thickness of the lower chassis, and the material cost can be saved because the height of the lower steel bowl 1 is low and the material consumption is reduced.
The manufacturing process of the lower steel bowl 1 comprises the following steps: the method selects stamping, heat treatment and electroplating processes, and comprises the following steps: (1) punching a wafer with a specified size by a punch, (2) pre-punching, (3) fine punching and forming, (4) punching and shaping an upper convex block and a lower convex block, (5) heat treatment, (6) electroplating the surface, and preparing a finished product.
