Abstract
The utility model discloses a double anchor ear bottom fork four-wheel all terrain motorcycle which comprises a bottom fork, a back wheel shaft, a chain disk and a brake flap, wherein, a left and a right anchor ears are arranged on the bottom fork and are respectively connected with the back wheel shaft through a left and a right shaft housings; both the chain disk and the brake flap are arranged between the left and the right shaft housings. In the double anchor ear bottom fork four wheel all-terrain motorcycle of the utility model, the bottom fork is of a double anchor ear structure, the number of the joint point of the shaft housings and the back wheel shaft is two, and the stress point of the back wheel shaft and the bottom fork is increased; the acting force forced on the center of the back wheel shaft originally is dispersed to the mounting position of the two shaft housings, at the same time, the bearing moment of the mounting position of each shaft housing is reduced; the mounting positions of the chain disk and the brake flap are at the inner side of the shaft housings, so as to enable the chain disk and the brake flap to be closer to the central position of the whole motorcycle; the acting force of the motorcycle is enabled to act on the chain disk and the brake flap which are close to the center surface when traveling or braking, thereby the sideslip is not easy to happen during traveling or braking.
Description
Technical field
The utility model relates to a kind of four-wheel motor cycle, especially adopts the full landform motor bike of double embrace hoop chain stay four-wheel of double embrace hoop chain stay structure, suitable multiple highway pavement.
Background technology
Locking hood type chain stay, the back axle of existing four-wheel all-terrain vehicle are single locking hood type, and chain drum and disc brake are installed all in the anchor ear both sides, vehicle travel or glancing impact because application force all acts on the chain drum or brake disc on non-central, cause vehicle easily to break away.And because the suffered moment loading point of hind axle on the point in center, easily causes hind axle being subjected to rupturing influence driving safety under the impulsive force situation.Be called " a kind of plate disc brake connects support and uses the connection structure of this support ", the patent No. the disclosed connection structure of Chinese utility application file as name as ZL200520009693.7, adopt single anchor ear structure to connect exactly, be connected on the rear-axle casing.This kind structure has only the mono-stress point, and is inhomogeneous at the application force that travels or the glancing impact back axle is subjected to, and application force all acts on the non-central point, and vehicle easily breaks away, and it is not steady to travel.
Summary of the invention
The utility model is at the above-mentioned deficiency of the four-wheel motor cycle of prior art, a kind of chain stay is provided is double embrace cuff structure, back axle travel or application force that glancing impact is subjected to more near the full landform motor bike of double embrace hoop chain stay four-wheel of car load center.
The technical solution of the utility model: the full landform motor bike of double embrace hoop chain stay four-wheel, comprise chain stay, hind axle, chain drum and brake disc, it is characterized in that: on chain stay, be provided with left anchor ear and right anchor ear; Left side anchor ear is connected with hind axle with right axle sleeve through left axle sleeve respectively with right anchor ear; Chain drum and brake disc all are arranged on left axle sleeve and right axle sleeve inboard.
Further feature is: left axle sleeve and right axle sleeve are with respect to the center symmetry of hind axle, and chain drum and brake disc are with respect to the center symmetry of hind axle.
The full landform motor bike of double embrace hoop chain stay four-wheel of the present utility model has following characteristics:
1, chain stay is the double embrace cuff structure, and warp beam sleeve and hind axle bonded assembly point of connection are two, have increased the stress point of hind axle and chain stay; Originally the application force that concentrated on the hind axle center is decomposed on two axle sleeve installation sites, also reduced the moment of bearing of each axle sleeve installation site simultaneously.
2, the installation site of chain drum and brake disc is all in the axle sleeve inboard, thereby allows chain drum and brake disc more near the center of car load.Make vehicle travel or the glancing impact application force all acts near on the chain drum or brake disc of longitudinal plane of symmetry like this, therefore travelling or glancing impact is difficult for breakking away.
3, improve the safety and the driver comfort of car load, can adapt to the needs of multiple highway pavement.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is chain stay of the present utility model (part a 1) structural representation;
Fig. 2 is hind axle of the present utility model (part 4) mounting structure figure;
The specific embodiment
In Fig. 1,2,1-chain stay, 2-left side anchor ear, the right anchor ear of 3-, 4-hind axle, 5-left axle sleeve, 6-right axle sleeve, 7-chain drum, 8-brake disc;
The full landform motor bike of anchor ear chain stay four-wheel of the present utility model comprises chain stay 1, hind axle 4, chain drum 7 and brake disc 8, and chain stay 1 warp beam sleeve is connected with hind axle 4, and chain drum 7 and brake disc 8 are arranged on the hind axle 4.On chain stay 1, at chain stay 1 position that is connected with hind axle 4, be provided with left anchor ear 2 and right anchor ear 3, left anchor ear 2 is connected with hind axle 4 with right axle sleeve 6 through left axle sleeve 5 respectively with right anchor ear 3; Chain drum 7 and brake disc 8 all are arranged between left axle sleeve 5 and the right axle sleeve 6, and side within it is near the center of hind axle 4; Optimum structure is left axle sleeve 5 and the right axle sleeve 6 center symmetry with respect to hind axle 4, and chain drum 7 and brake disc 8 are with respect to the center symmetry of hind axle 4.During practical set, left axle sleeve 5 and right axle sleeve 6, chain drum 7 and brake disc 8 also can have certain deviation not with respect to the center symmetry of hind axle 4.(hind axle 4 centers on the car load vertical central plane, chain drum 7 and driving engine output chain gear＜fly for a short time on same vertical surface).
Consider that from easily manufactured, enhancing interchangeablity equal angles left anchor ear 2 and right anchor ear 3 are identical, left axle sleeve 5 and right axle sleeve 6 are identical.
Chain stay 1 plays effects such as bearing gravity as the chain stay of existing four-wheel motor cycle; Hind axle 4 is to drive the wheel shaft that left and right sides trailing wheel rotates, be the parts of existing four-wheel motor cycle, chain drum 7 is connected with power transmission chain, when motor cycle engine rotates outputting power moment, driving chain through speed reduction gearing, power-transfer clutch etc. rotates, chain drives chain drum 7 again and rotates, and chain drum 7 drives the hind axle 4 and the left and right sides trailing wheel that are attached thereto and rotates, and orders about motor bike to overtake.Brake disc 8 is brake components of motor bike, and when the needs braking brake, rolling brake handle or step on brake pedal acts on the brake disc 8 through brake stay cord etc., acts on hind axle 4 or the left and right sides rear-wheel hub through brake disc 8, reaches the brake snub effect.
