Description

The split type vehicle frame of beam bending bicycle

Technical field

The utility model relates to technical field of motorcycles, and in particular to a kind of split type vehicle frame of beam bending bicycle.

Background technique

Beam bending bicycle is one of current most common motorcycle vehicle, because it is with economical and practical, simple operation and other advantages, and It is deep to be liked by vast motorcycle fan.Existing frame of curved beam motorcycle is usually monolithic construction, i.e., in a manner of welding etc. Each sheet metal member is combined as a whole, is reduced using the damper of vehicle rear because the reasons such as road bump are transmitted to vehicle in traveling Vibration on frame, to guarantee the comfort of vehicle.

Due to its special body construction, for riding type car or off-road motorcycle, beam bending bicycle is mated formation by non- Passability when road surface shows slightly insufficient, and therefore, how to improve beam bending bicycle cross-country ability under the premise of ensuring comfort becomes Technical problem urgently to be resolved.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of split type vehicle frame of beam bending bicycle, to solve existing camber beam The technical problem of vehicle cross-country ability deficiency.

To achieve the above object, technical solutions of the utility model are as follows:

A kind of split type vehicle frame of beam bending bicycle, including body after vehicle frame head pipe and vehicle frame, it is characterised in that: on the vehicle frame head pipe With the attachment base that inclined downward backward extends, body front end is installed with connecting bracket after vehicle frame, props up in the attachment base with connecting Damper is connected between frame.

Using the above structure, body after vehicle frame head pipe and vehicle frame is split as two independent sectors, and is connected by damper, In vehicle travel process, vehicle head part can generate relative motion with body tail, and absorbed using damper and transmitted by ground There is bigger deflection, simultaneously as body after vehicle frame relative to traditional Integral vehicle frame structure to the vibration of vehicle body Vibration can be damped device absorption, the rear damping for being originally arranged at body tail can be cancelled, to simplify body tail Structure is conducive to increase the gap between rear-wheel and vehicle frame, so that vehicle passability enhances, effectively increases the cross-country of beam bending bicycle Performance.

For the support function for realizing body after vehicle frame, and facilitate the installation of damper and cushion, body includes branch after the vehicle frame Support section and the saddle section extended rearwardly and upwardly by the supporting section rear end have cushion mounting portion, connecting bracket in saddle section rear end It is installed in supporting section front end.

Preferably, the connecting bracket includes the rack body of plate-like structure, which is equipped with interconnecting piece, The rack body side has along the outwardly extending connecting support of its width direction, and connecting support distal end is equipped with connecting hole. Using the connecting bracket of the structure, it can be ensured that damper is reliably connected, and the setting of connecting support helps to improve connection branch The rigidity of frame simultaneously facilitates the installation of body accessories to fix.

To ensure that attachment base has sufficient intensity, the attachment base and vehicle frame head pipe are integrally formed, in vehicle frame head pipe There is angle between mandrel line.

The damper is preferably external air-bag vibration damper, including working cylinder, damping spring and is connected to working cylinder one The cylinder block of side.The structure utilizes the adjustable characteristic of air sac type damping device, according to different road conditions conditions or can travel needs, Damper stiffness is adjusted, to enhance adaptability of the beam bending bicycle under various road conditions or riving condition, improves user experience.

The utility model has the advantages that

It is absorbed and is vibrated using damper by split-type design using the split type vehicle frame of the beam bending bicycle of above technical scheme, Beam bending bicycle cross-country ability can be effectively improved, have structure novel, good reliability, it is easy for installation the advantages that.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of connecting bracket in the utility model.

Specific embodiment

The utility model is described in further detail with attached drawing with reference to embodiments.

The split type vehicle frame of beam bending bicycle as shown in Figure 1, including body 2 after vehicle frame head pipe 1 and vehicle frame, wherein vehicle frame head pipe 1 is big Cause be tubular structure, for installing the body structures component such as headstock, after vehicle frame body 2 include supporting section 22 and from the supporting section 22 to The saddle section 23 that back upper place extends, in the rear end of saddle section 23, the cushion saddle portion 24 of generally horizontal structure, is different from tradition Integral vehicle frame structure, body 2 is mutually indepedent after vehicle frame head pipe 1 and vehicle frame, and is connected by damper 3.

In order to facilitate the installation of damper 3, the middle part of vehicle frame head pipe 1 is equipped with the attachment base extended with inclined downward backward 11, attachment base 11 is integrally formed with vehicle frame head pipe 1 or is fixed with one by welding manner and vehicle frame head pipe 1, extending direction It is central axial with angle with vehicle frame head pipe 1.Body 2 is fixedly arranged at the front end with connecting bracket 21 in supporting section 22 after vehicle frame.

Referring to figure 2., connecting bracket 21 is metallic stamping pieces, using mold one-pass molding comprising one is substantially plate-like The rack body 21a of structure is equipped with the interconnecting piece 21b extended forward in the front end of rack body 21a, in rack body 21a mono- Side has along the outwardly extending two connecting support 21c of its width direction, body accessories is connected when facilitating vehicle to assemble, and increase The rigidity of strong ties bracket 21, two connecting support 21c are symmetrical, are located at close to the rear and front end rack body 21a End position.

Similar with the mounting means of traditional rear shock absorber, 3 front end of damper is mounted on the attachment base 11 of vehicle frame head pipe 1, Rear end is connected on the interconnecting piece 21b of connecting bracket 21, and in the present embodiment, damper 3 preferably uses external air-bag vibration damper, Including working cylinder 31, the damping spring 32 for being set in 31 outside of working cylinder and the cylinder block 33 for being connected to 31 outside of working cylinder.Resistance Buddhist nun's device 3 is installed rear inclined posture, and the vibration in vehicle travel process after body 2, is made after being transferred to vehicle frame in damper 3 Under, body 2 and vehicle frame head pipe 1 after vehicle frame is set to generate appropriate relative motion, by absorption of vibrations, in this way, no longer needing in body tail It arranges rear shock absorber, body tail space is released, to effectively increase the cross-country ability of beam bending bicycle.

Finally, it should be noted that foregoing description is only the preferred embodiment of the utility model, the common skill of this field Art personnel are under the enlightenment of the utility model, under the premise of without prejudice to the utility model aims and claim, can make Multiple similar expressions, such transformation are each fallen within the protection scope of the utility model.
