Abstract

The utility model discloses a motorcycle secondary damping mechanism, which includes a damping sleeve. The key point is that a circular surface of a rubber bumper inside the damping sleeve is machined into a tooth form; an upper damping sleeve and a lower damping sleeve are formed via the vulcanization by an inner tube and a rubber bumper. Firstly two damping sleeves are loaded into a front frame support by mode of the clearance fit and connected with an front support and an hanging rack of the engine simultaneously; then two upper damping sleeves are loaded into upper part of the bracket by mode of clearance fit and connected with a rear frame support of the frame; finally two lower damping sleeves are loaded into lower part of the damping bracket by mode of clearance fit and connected with a rear end of the hanging rack simultaneously to form the secondary damp, which avoids the insufficiencies of prior art technology, such as fixation of the damping sleeve on the frame, small pressure stroke of the rubber and unclear of the damping effect, and is simple in manufacture, low in cost.

Description

The motorcycle secondary damper mechanism

Technical field

The utility model relate to a kind of can the vibration of effective attenuation motor bike when driving, improve the motorcycle secondary damper mechanism that drives traveling comfort.

Background technology

As everyone knows, vehicle frame and driving engine have connected and composed the motor bike main body, and the power of motor bike is transmitted by driving engine, and the connection mode of itself and vehicle frame directly has influence on the traveling comfort when driving motor bike.

At present, the following two kinds of connection modes of main employing between the vehicle frame of motor bike and the driving engine:

One, with bolt direct connection driving engine and vehicle frame, no any vibration-proof structure between vehicle frame and the driving engine.When motor bike moves,, cause that motor bike produces severe jolt, has a strong impact on the driving comfort and the physical and mental health of chaufeur owing to, very easily produce resonance during engine output power with vehicle frame without any vibration-proof structure.

Two, the vibration damping cover is arranged between driving engine and the vehicle frame.But this vibration damping cover generally is to form by sulfuration with two metal tubes and rubber, and is embedded in the vehicle frame support by interference fit, is connected the back with driving engine and plays damping of vibrations by rubber compression in the vibration damping cover.Its major defect is that vibration damping is enclosed within on the vehicle frame is to fix, and the rubber compression stroke is less, and damping of vibrations is performance fully not, and effectiveness in vibration suppression is not obvious.

Summary of the invention

The purpose of this utility model is to overcome the not defective of performance fully of existing vibration damping cover damping of vibrations, and provide a kind of can the vibration of effective attenuation motor bike when driving, improve the secondary damper mechanism that drives traveling comfort.

The purpose of this utility model can reach by following technical measures, that is: this motorcycle secondary damper mechanism, comprise the vibration damping cover, its key is: the yielding rubber side face in the vibration damping cover is processed as profile of tooth, forms vibration damping cover and following vibration damping cover by interior pipe, yielding rubber respectively by sulfuration; At first go up the front vehicle frame that the vibration damping covers pack on the vehicle frame in the mode of free-running fit and support two, and with driving engine before support, the engine hanger front portion is connected simultaneously; Go up the vibration damping covers with the mode of the free-running fit damping frame top of packing into two again, and with vehicle frame on back vehicle frame support and connection; At last with two following vibration damping covers with the mode of the free-running fit damping frame bottom of packing into, and be connected simultaneously with the engine hanger rear portion, form the secondary damper mechanism, when making the motor bike operation, because the influence of secondary damping of vibrations is arranged, the rubber compression stroke is bigger, more because the vibration damping cover belongs to free-running fit with vehicle frame, the vibration damping cover can be compressed in any direction and play damping of vibrations, thus the vibration that the effective attenuation driving engine brings, and more increasing drives traveling comfort.

The beneficial effects of the utility model are: can bring into play the damping of vibrations of vibration damping cover to greatest extent, and manufacturing is simple, cost is low.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, a kind of motorcycle secondary damper mechanism of the utility model, comprise the vibration damping cover, its key is yielding rubber 2 side faces in the vibration damping cover are processed as profile of tooth, forms vibration damping cover 14 and following vibration damping cover 10 by interior pipe 1, yielding rubber 2 respectively by sulfuration; At first go up the front vehicle frame that vibration damping cover 14 packs on the vehicle frame in the mode of free-running fit and support 5 two, and with driving engine 4 before support, engine hanger 6 front portions are connected simultaneously; Go up vibration dampings cover 14 with the mode of free-running fit damping frame 7 tops of packing into two again, and support 5 and be connected with back vehicle frame on the vehicle frame; At last with two following vibration dampings covers 10 with the mode of free-running fit damping frame 7 bottoms of packing into, and be connected simultaneously with the engine hanger rear portion.

Described yielding rubber 2 is a free-running fit with packing ring 3.

The tooth depth of described yielding rubber 2 side face profiles of tooth is 1/5 of the monolateral thickness of yielding rubber, Yi Bian and be the flange state.

Described secondary damper mechanism mainly by vehicle frame support 5, driving engine 4, engine hanger 6, go up vibration damping cover 14, vibration damping cover 10, damping frame 7, nut 8, bolt 9 are formed down, wherein: driving engine 4 is to link together by the middle part through hole of driving engine 4 and engine hanger 6 with bolt 9, nut 8 in advance with engine hanger 6; The structure front portion is linked together by vehicle frame support 5, driving engine 4, engine hanger 6, last vibration damping cover 14 usefulness bolts 9, nut 8; Top, structure rear portion connects vehicle frame with bolt 9, nut 8 and supports 5, goes up vibration damping cover 14, damping frame 7 tops; The structure lower rear connects vibration damping cover 10, damping frame 7 bottoms, engine hanger 6 down with bolt 9, nut 8.

In the direction on a plane, as shown in Figure 2, when motor bike moved, driving engine 4 power were transferred to down vibration damping cover 10 by engine hanger 6, and following vibration damping cover 10 is owing to the vibration that driving engine 4 power produce is compressed, played buffer action, a part of vibration that decayed, when the vibration that is not attenuated by damping frame 7, when going up vibration damping cover 14 and being transferred to vehicle frame and supporting 5, last vibration damping overlaps 14 and at this moment plays buffer action equally, the residual vibration that decays more, the secondary damper mechanism plays a role.

In the direction on another plane, the flange state of following vibration damping cover 10 plays buffering, damping of vibrations equally.In order to prevent that yielding rubber 2 from being supported the wearing and tearing when compressing of 5 end faces by vehicle frame, the special packing ring 3 that increases prevents undue wear.

This structure all plays damping of vibrations in any direction.
