Detailed Description
The gearbox supporting cover of the pedal electric motorcycle is of an integrated structure and is composed of a supporting cover body 1 (see the attached figures 1 and 2 in the specification). The gear box supporting cover is formed by die-casting aluminum materials, so that the gear box supporting cover can utilize the relatively light characteristic of the aluminum materials, the overall weight of the gear box supporting cover is reduced, and in addition, when the gear box supporting cover is manufactured by a die-casting mode, the gear box supporting cover can be more compact and higher in strength, and further the gear box supporting cover can meet the use requirement of a gear box of a pedal electric motorcycle.
A plurality of reinforcing columns 2 are arranged on the side surface of the supporting cover body 1; the reinforcing column 2 is provided with a mounting hole 3 (see the attached figures 1 and 2 of the specification). The supporting cover body 1 can be installed and fixed on a gear box of the pedal electric motorcycle through the assembling hole 3. The purpose of providing the fitting hole 3 on the reinforcing column 2 is to: the stress strength at the assembling hole 3 of the supporting cover body 1 is strengthened in a shape-specific manner, so that the problem that the supporting cover body 1 is broken at the assembling hole 3 in the using process is avoided.
The inner part of the supporting cover body 1 is provided with a middle supporting ring 5; one side of the middle support ring 5 is provided with an output support ring 4; the other side of the middle support ring 5 is provided with an input support ring 6; the middle support ring 5, the output support ring 4 and the input support ring 6 are arranged in a triangular shape.
During assembly, the output support ring 4 has the function of supporting the output shaft of the gearbox of the pedal electric motorcycle; the input support ring 6 has the function of supporting the input shaft of the gearbox of the pedal electric motorcycle; the intermediate support ring 5 has the function of supporting the intermediate shaft of the gearbox of the pedal electric motorcycle.
The middle support ring 5 is jointed and connected with the output support ring 4 and the input support ring 6; bearing assembling positions are arranged inside the output support ring 4 and the middle support ring 5; a positioning output hole 17 is arranged in the output support ring 4; the positioning output hole 17 is in a step-shaped structure (see the attached figure 1 in the specification).
The output support ring 4 carries out positioning support on a bearing of the output shaft of the gearbox of the pedal electric motorcycle through a positioning output hole 17; the middle support ring 5 is used for positioning and supporting a bearing of a middle shaft of the gearbox of the pedal electric motorcycle through a bearing assembling position; the input support ring 6 positions and supports a bearing of the input shaft of the gearbox of the pedal electric motorcycle through a bearing assembling position.
The upper side of the output support ring 4 is provided with an oiling reinforcing rib 10; an oil filling hole 11 is formed in the oil filling reinforcing rib 10; the positioning output hole 17 is communicated with the outside through the oil filling hole 11. After the assembly is completed, people can inject lubricating oil into the positioning output hole 17 through the oil injection hole 11, so that the lubricating oil can provide lubrication for a bearing of an output shaft of a gearbox of the pedal electric motorcycle.
One side of the middle support ring 5 is connected with the output support ring 4, the input support ring 6 and the bottom end of the support cover body 1 through a reinforcing cross beam 7 (refer to the attached figures 1 and 2 in the specification). One side of the output support ring 4 is connected with the inner wall and the bottom surface of the support cover body 1 through a plurality of reinforcing rib plates A8; one side of the middle support ring 5 is connected with the inner wall and the bottom surface of the support cover body 1 through a plurality of reinforcing rib plates B9 (refer to the attached figures 1 and 2 of the specification). The output support ring 4 is strengthened in connection strength with the support cover body 1 through a strengthening rib plate A8; the middle support ring 5 is reinforced in connection strength with the support cover body 1 by a reinforcing rib plate B9. Therefore, the problem of tension fracture between the middle support ring 5 and the output support ring 4 and the support cover body 1 during assembly can be avoided.
One end of the output support ring 4 extends to the outside of the bottom of the support cover body 1 (see the attached figure 3 in the specification). When the pedal electric motorcycle is in work, the output support ring 4 plays a role of supporting the output shaft of the gearbox of the pedal electric motorcycle; the output shaft of the gearbox of the pedal electric motorcycle has the characteristic of the maximum stress at the output end of the output support ring 4, so the aim of the output support ring 4 is that: the output end of the output support ring 4 is reinforced in a targeted manner, so that the problem of 'cracking' during the operation is prevented.
A plurality of connecting lugs 12 are arranged on one side below the supporting cover body 1; the connecting lug 12 is in a triangular structure; the end of the connecting support lug 12 is provided with a connecting hole 13, and the connecting support lug 12 is provided with a lightening hole 14 (see the attached figures 1 and 2 in the specification); the supporting cover body 1 is fixedly connected with a pedal electric motorcycle frame through a connecting support lug 12 and a connecting hole 13.
A reinforcing coaming 15 is arranged on the supporting cover body 1 at one side of the input supporting ring 6; the reinforcing coaming 15 is of an L-shaped structure (see the attached figures 1 and 2 in the specification); two ends of the reinforcing coaming 15 are respectively connected with the inner wall of the supporting cover body 1; a Y-shaped rib plate 16 (refer to the attached figures 1 and 2 in the specification) is arranged in the supporting cover body 1 inside the reinforced enclosing plate 15. The purpose of arranging the reinforcing coaming 15 and the Y-shaped rib plate 16 is as follows: the strength of the input support ring 6 is purposefully reinforced to reduce the risk of "force fracturing" thereof.
The gearbox supporting cover of the pedal electric motorcycle is compact in structure and ingenious in design, and the structure is specially designed according to the stress condition of the gearbox supporting cover, so that the weight can be relatively reduced, the strength using requirement can be met, and the problems that the existing gearbox supporting cover is heavy and the performance of the whole motorcycle is affected are solved; is particularly suitable for the use requirement of the pedal electric motorcycle.
