The specific embodiment
Fig. 1 is the structural representation of the utility model bending beam type motorcycle vehicle frame, and Fig. 2 is the lateral plan of the utility model bending beam type motorcycle vehicle frame.As Fig. 1, shown in Figure 2, the agent structure of bending beam type motorcycle vehicle frame comprises interconnective girder 10, cradle 20 and tailstock 30, its middle girder 10 comprises two the left vehicle frame pipe 11 and the right vehicle frame pipes 12 that are symmetrical arranged and form twin-spar construction, the front end of left side vehicle frame pipe 11 and the front end of right vehicle frame pipe 12 extend to the front portion of seat tube 40, and the loading side arm 44 of before the anterior affixed formation closed form of seat tube 40, dashing forward, loading side arm 44 formed spaces can be used for loading, improve cargo bay of the present utility model, loading side arm 44 formed preceding dashing forward can be used as collision protection structure simultaneously, improve anti-collision capacity of the present utility model.Particularly, the front end of left vehicle frame pipe 11 can be connected by vehicle frame pipe front connector 43 with the front end of right vehicle frame pipe 12, improves cargo bay of the present utility model and anti-collision capacity to greatest extent.
Further, the rear end of the rear end of left vehicle frame pipe 11 and right vehicle frame pipe 12 is affixed with the front end of tailstock 30 respectively, makes left vehicle frame pipe 11 and right vehicle frame pipe 12 form the twin-spar construction of closed form.Cradle 20 is positioned at the below of girder 10, comprise two symmetrically arranged left lower side pipes 21 and limit, bottom right pipe 22, left lower side pipe 21 is connected with middle lower transverse tubule 26 by preceding lower transverse tubule 25 respectively with limit, bottom right pipe 22, makes left lower side pipe 21 and limit, bottom right pipe 22 form the framed structure of closed form.Left lower side pipe 21 is connected with left vehicle frame pipe 11 by left front stay tube 23, and limit, bottom right pipe 22 is connected with right vehicle frame pipe 12 by right front stay tube 24, makes girder 10 and cradle 20 form the three-dimensional truss structure of closed.Tailstock 30 is positioned at the rear of girder 10, the vehicle frame tail pipe 31 that comprises closed form, the front end of vehicle frame tail pipe 31 is connected with the rear end of left vehicle frame pipe 11 and the rear end of right vehicle frame pipe 12 respectively, the left back stay tube 33 that passes on left at vehicle frame tail pipe 31 middle parts is connected with left lower side pipe 21, the right side at vehicle frame tail pipe 31 middle parts is connected with limit, bottom right pipe 22 by right back stay tube 34, the postmedian of vehicle frame tail pipe 31 also is provided with after cross member 32, makes girder 10, cradle 20 and tailstock 30 form the unitized frame of closed.
As shown in Figure 1 and Figure 2, left side vehicle frame pipe 11 and right vehicle frame pipe 12 are the camber beam of middle part to lower recess, girder 10 is formed between motor bike head and tailstock 30 accommodation space of horizontal engine can be installed, and finally form the sealing of bending beam type motorcycle vehicle frame, preceding prominent, camber beam, cradle-type framed structure.
In the utility model technique scheme, the vehicle frame pipe front connector of the left vehicle frame pipe 11 of girder 10 and right vehicle frame pipe 12 by front end is 43 affixed, the rear end is affixed with tailstock 30, makes the twin-spar construction of girder 10 formation closed forms, so the rigidity of girder 10 and intensity height.Simultaneously, the front portion of the utility model left side vehicle frame pipe 11 and right vehicle frame pipe 12 exceeds seat tube 40 positions, after the connection seat tube 40 is included within the loading side arm 44, therefore form the preceding lug structure that is used for the cargo-carrying cargo bay and possesses anti-collision capacity, further improved cargo bay of the present utility model and anti-collision capacity.
The left lower side pipe 21 of the utility model cradle 20 is connected with girder 10 with limit, bottom right pipe 22 framed structures by closed form, make the three-dimensional truss structure of girder 10 and cradle 20 formation closeds, so the utility model vehicle frame has fabulous rigidity and intensity.The vehicle frame tail pipe 31 of tailstock 30 has further been strengthened the utility model rigidity of frame and intensity by being connected with cradle 20 with girder 10 respectively.
The utility model girder 10 adopts the front-end and back-end height and the curved beam type configuration of medial recess, makes the whole camber beam closed framework that forms of vehicle frame.This curved beam type configuration of the utility model makes and forms a vacancy space between motor bike head and the seat cushion, compare with the prior art riding-type motorcycle, chaufeur get on the bus, when getting off, leg can directly stride across from this vacancy space, the movement range of health is little, it is very convenient to get on the bus, get off, and can not influence getting on the bus, getting off of chaufeur owing to the motor bike afterbody is loaded with goods.
The bottom of sunk area is a flat segments on the utility model girder 10, make that the utility model vehicle frame middle part institute is stressed to be disperseed to both sides fully, there is bigger rigidity at the middle part, can bear heavy duty, can increase the vacancy space between headstock and the seat cushion to greatest extent, thereby the position of lade in the middle part of car load is provided for motor bike.In actual use, motorcycle front-wheel is positioned at the front end below of vehicle frame, and trailing wheel is positioned at the below, rear end of vehicle frame, makes the utility model vehicle frame outstanding at the head and the afterbody of motor bike, also provides more bigger locational spaces for the motor bike loading.Because the vibration of horizontal engine is bigger, the closed form twin-spar construction that the utility model adopts left vehicle frame pipe and right vehicle frame pipe to form, and has sunk area, the front portion of sunk area is taken advantage of a situation upwards curved along the housing of driving engine, and strengthen standpipe 41 by a left side respectively and the right standpipe 42 of strengthening couples together total sealing ground and firmly welds, not only efficiently solve the single girder rigidity of prior art and can not satisfy the defective that the horizontal engine operating needs is installed inadequately, and cargo bay in the middle part of having increased, obtain the bigger ground Clearance, the fit structure compactness of while sunk area and cradle structure, rigidity requirement can be satisfied, the vibration of horizontal engine can be reduced again.
The utility model adopts sealing, preceding prominent, camber beam, cradle-type framed structure, be interconnected to close-shaped between each main stressed member of formation vehicle frame, framework single-piece rigidity and intensity have been increased, not only satisfy the heavily loaded requirement of motor bike to greatest extent, and the formed space of loading side arm can be used for loading, improve cargo bay of the present utility model, dashing forward before the loading side arm is formed can be used as collision protection structure, improves anti-collision capacity of the present utility model.
It should be noted that at last: above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
