Description

Carbon fiber type electric motorcycle bottom fork

Technical Field

The utility model discloses the application belongs to the technical field of motorcycle, specifically discloses a carbon fiber formula electric motorcycle car chain stay.

Background

A bottom fork is widely used in vehicles such as motorcycles and electric vehicles, and is one of main components for fixing a rear wheel at the rear of a vehicle body and for connecting the rear wheel to a vehicle frame.

The driving motors of the existing vehicles such as electric vehicles and the like are arranged on rear wheel shafts, although the efficiency of the motors can be improved by the design, the position of the rear wheel shafts is limited, the shapes, the sizes or the power of the motors are limited, the motors are easily subjected to large load of the rear wheel shafts when being arranged on the rear wheel shafts, the performance of the electric vehicles is directly limited, and in the process of arranging the motors on the rear wheel shafts, the installation requirements are high, and the installation process is complex.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a carbon fiber formula electric motorcycle car chain stay aims at making things convenient for the installation of motor more, and reduces the requirement to motor size, shape.

In order to achieve the above object, the basic scheme of the utility model is:

carbon fiber formula electric motorcycle car chain stay, including the crotch that two mutual symmetries set up, two fixedly connected with crossbeam between the crotch, the crossbeam bottom is equipped with the motor mounting panel, the motor mounting panel includes two risers, perpendicular fixedly connected with diaphragm between two risers, the diaphragm with the connection can be dismantled to the crossbeam, two the mounting hole has all been seted up on the riser, two the mounting hole symmetry set up.

The working principle and the beneficial effects of the basic scheme are as follows:

1) the crossbeam is connected between two crotch among this technical scheme, and such setting can improve the stability of whole chain stay, strengthens the intensity of whole chain stay to make the chain stay install can form more stable supporting role after on rear wheel and frame.

2) In addition, the motor mounting plate is arranged at the bottom of the cross beam in the technical scheme, the defect that the requirement on the shape and the size of the motor is high when the motor is mounted on the rear wheel in the prior art can be effectively overcome, the motor mounting plate in the technical scheme can simplify the mounting of the motor, and the mounting steps are simpler than those of the motor mounted on the rear wheel.

3) In the technical scheme, the motor is arranged on the cross beam between the two fork frames, so that the influence on the rear wheel in the running process can be reduced, and the load of the rear wheel is reduced.

4) The motor mounting panel includes two risers among this technical scheme, is provided with the diaphragm between two risers perpendicularly, and in such setting, two risers are used for supporting the motor, and the diaphragm can realize being connected between motor mounting panel and the whole chain stay to the realization is to the installation of motor.

Furthermore, the fork frames respectively comprise a front plate, a middle plate and a rear plate which are sequentially distributed along the length direction of the fork frames, the cross beam is connected at the junction of the front plate and the middle plate, and the length of the front plate is smaller than that of the middle plate.

So set up, make things convenient for the installation of rear wheel more, make the rear wheel can be located between two crotch, and can avoid the crossbeam to produce the hindrance to the installation of rear wheel to make the frame distance of rear wheel and motorcycle close to relatively, and accord with the production technology of motorcycle, avoid between rear wheel and the motorcycle apart from too big, and weaken the antitorque square power of motorcycle.

Further, offer the shrinkage pool that is the U-shaped on the diaphragm, the width of shrinkage pool is greater than the width between two chain stay front plates, the both sides of shrinkage pool can be dismantled with two front plates respectively and be connected.

The setting up of shrinkage pool among this technical scheme can make the diaphragm adapt to the shape that two chain stays and crossbeam formed after being connected to strengthen the aesthetic property of whole chain stay, and can also reduce the weight of diaphragm, make whole motor mounting panel light more.

Furthermore, a plurality of fixing holes are formed in the transverse plate, and connecting holes which are opposite to the fixing holes in sequence are formed in the front plate.

The setting of fixed orifices and connecting hole among this technical scheme makes things convenient for more to realize fixing diaphragm and crossbeam and convenience with diaphragm and front bezel.

Further, the fixing holes are all in a long round hole structure.

So set up, when the installation motor mounting panel, make the motor mounting panel have the adjustability, reduced the installation accuracy of fixed orifices and connecting hole, when fixing the diaphragm promptly, can remove the diaphragm according to actual conditions, the bolt that uses in connecting fixed diaphragm can pass fixed orifices and connecting hole.

Further, all seted up a plurality of bolt holes on the riser.

When the motor is convenient to install due to the arrangement of the bolt holes in the technical scheme, the motor is fixed by inserting fixing pieces (such as bolts) into the bolt holes.

Further, the angle between the rear plate and the middle plate is an obtuse angle.

The angle between back plate and the medium plate is the obtuse angle among this technical scheme, and such setting can make the chain stay rear portion be connected the assembly with the rear wheel of motorcycle simpler, and can form stronger steadiness with the rear wheel to improve the stationarity of whole chain stay.

Further, the width of the middle plate is sequentially reduced along the length direction, the large end of the middle plate is connected with the front plate, and the small end of the middle plate is connected with the rear plate.

So set up for between two yokes more stable, and compare in the equal phase of width on the crotch length direction, the crotch antitorque square among this technical scheme is stronger, when the motorcycle is at high-speed bending, the chain stay among this technical scheme is difficult to receive great torsion and produces the deformation.

Further, the upper end fixedly connected with of crossbeam has two bumper shock absorber mounting brackets that mutual symmetry set up.

So set up, the setting of bumper shock absorber mounting bracket is convenient for at crotch and motorcycle rear wheel and with the connected back of frame, through installation damping device between the saddle of crossbeam and motorcycle to play absorbing effect.

Further, the fork frame is made of carbon fiber materials.

So set up, can make whole chain stay quality light, intensity is high, the good reliability.
