Abstract
The utility model discloses a disconnect type rear axle, comprising a rear axle spindle, a rear flat fork and a rear axle housing. The rear axle housing consists of a left rear axle housing and a right rear axle housing; the left and right rear axle housings are composed of shaft sleeves and fixing plates which are arranged on the shaft sleeves and vertical to the shaft center of the shaft sleeves. The left and right rear axle housings are connected on the rear flat fork of a beach vehicle by the fixing plates and are connected with the rear wheel spindle by bearings which are mounted inside the shaft sleeves. The disconnect type rear axle has simple structure, convenient manufacture and reasonable load distribution; the disconnect type rear axle can decrease the weight of the whole beach vehicle.
Description
Technical field
The utility model relates to a kind of back bridge construction, is the back bridge construction of four-wheel beach buggy specifically, and that this back axle has is simple in structure, layout and load are reasonable, is convenient to alleviate the advantage of complete vehicle weight.
Background technology
Full landform four-wheel beach buggy (being called for short beach buggy or ATV), it is a kind of emerging special vehicle, because its good cross-country traveling ability and economy, make it in worldwide, obtain fast development rapidly, but the various theoretical foundations of relevant beach buggy design-calculated, parameter choice, version etc. also are in the continuous stage of fumbling.
Present four-wheel beach buggy back axle assembly is an integral structure, and its rear-axle casing and hind axle, drag seat are one, at the back axle two ends long bushing are arranged, and this back axle has the shortcoming of complex structure, processing, assembling inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of separation type back axle, to overcome the above-mentioned deficiency of existing whole back bridge construction.
Separation type back axle of the present utility model, comprise hind axle, back chain stay and rear-axle casing, rear-axle casing is made up of a left back axle housing and a right back axle housing, left and right rear-axle casing is made up of the adapter plate vertical with the axle sleeve axle center on axle sleeve and the axle sleeve, left and right sides rear-axle casing is connected on the chain stay of back by adapter plate, and left and right rear-axle casing links by bearing and the hind axle that is contained in the axle sleeve.
On the described hind axle bearing step can be arranged, in the axle sleeve axis hole of described left and right rear-axle casing the bearing step be arranged, described bearing is positioned between the bearing step and the bearing step on the left and right rear-axle casing of hind axle.
The center of described hind axle can be fixed with disc brake seat and sprocket wheel.
Described sprocket wheel can be fixed on the disc brake seat.
On described sprocket wheel and the disc brake seat a plurality of through holes can be arranged, bolt be arranged sprocket wheel fixedly on the disc brake seat in the through hole.
Described disc brake seat and sprocket wheel can be structure as a whole.
The separation type back axle that this four-wheel beach buggy of the present utility model is used also can be applicable on other vehicle, and its hind axle and left and right rear-axle casing and disc brake seat adopt and divide body structure, have following advantage:
(1) because the left and right rear-axle casing that employing separates comes and the back chain stay is fixed, so do not want the two ends lining on the back axle; Disc brake seat and sprocket wheel adopt integrative-structure, can reduce a sprocket wheel or Der Bremssattel, so bridge construction is simpler after this separation type.
(2) back axle adopts and divides body structure, and the separation type rear-axle casing only is distributed in left and right bearing portion, can design rear-axle casing short and smallly as much as possible, has reduced to connect the materials of centre portion, simultaneously, can reduce complete vehicle weight; Right alignment between the left and right sides rear-axle casing itself is required effectively to be reduced, be convenient to processing and manufacturing and Assembling Production.
(3) because left and right rear-axle casing adopts isolating construction, make nearly possible Utopian being distributed on the hind axle of the stressed strong point of left and right rear-axle casing and hind axle, make that the hind axle external diameter is littler, processing capacity is littler, be convenient to reduce hind axle material therefor and tooling cost.
(4) because back axle is the branch body structure, each several part can be processed respectively, does not need large-scale blanked part and combinational processing method resemble the beam rear axle, has reduced difficulty of processing and cost.
(5) since sprocket wheel and disc brake seat be installed on the hind axle between the left and right rear-axle casing, so that the rational deployment of driving system and brake system.
Description of drawings
Fig. 1 is a kind of preferred embodiment structural representation of separation type back axle of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the separation type back axle comprises hind axle 1, left back axle housing 2, right back axle housing 3, disc brake seat 4, sprocket wheel 5 and back chain stay (omitting among the figure).Rear-axle casing is made of axle sleeve 21,31 and the adapter plate 22,32 that is welded on the axle sleeve 21,31, has through hole to be used for fixing by bolt and back chain stay on the adapter plate 22,32.Adapter plate 22,32 inboards (two rear-axle casings side in opposite directions) have with axle sleeve 21,31 accentric annular convex rings so that insert in the chain stay of back.The axis hole outside of left back axle housing 2 and right back axle housing 3 axle sleeves has stepped baffle ring formation bearing step 24,34 to be used for blocking bearing 23,33, by the bearing 23,33 that is contained in the left and right rear-axle casing left back axle housing 2 and right back axle housing 3 is equipped with on the hind axle 1.The diameter sudden change of hind axle 1 forms a step as bearing step 11, and bearing 33 is positioned between the bearing step 34 of bearing step 11 and right back axle housing 3, and hind axle 1 can not be moved axially with respect to the back chain stay; At the position that hind axle 1 middle part has a diameter to undergo mutation equally, the disc brake seat 4 of a spool-like is contained on the hind axle 1, and its right axle head withstands on the sudden change part of hind axle 1; Sprocket wheel 5 is fixed together by the disk on through hole 51 usefulness bolts and disc brake seat 4 right sides; Make sprocket wheel 5 and disc brake seat 4 relative fixed.Have an axle sleeve 6 to be installed on the hind axle 1 in disc brake seat 4 left sides, the bearing 23 that is contained in the left back axle housing 2 is positioned between the bearing step 24 of axle sleeve 6 and left back axle housing, and hind axle 1 is axially located.
Disc brake seat 4 is fixed on the center of hind axle 1 between left back axle housing 2 and right back axle housing 3, left back axle housing 2, disc brake seat 4, sprocket wheel 5 and right back axle housing 3 are evenly divided to be existed on the hind axle 1, make the even and dispersion of distribution of load, stressed reasonable, hind axle 1 local pressure concentration phenomenon can not occur, can effectively reduce the diameter of hind axle 1; Make the as close as possible car load centre plane of driving chain simultaneously, chain gear is more steady; The braking force of left and right sides trailing wheel is coordinated more.
