Description
Technical field
The invention belongs to the four-wheeled field, relate to the four-wheeled parts, what relate in particular to is the chain regulator of four-wheeled.
Background technology
The four-wheel beach buggy is a kind of emerging special vehicle, because its good off-road capability and economy, make it in worldwide, obtain fast development rapidly, but the various theoretical foundations of relevant four-wheel beach buggy design-calculated, parameter choice, version etc. also be in update, the stage of fumbling.
The chain regulator of at present known relevant four-wheel beach buggy trailing wheel, its role is to be used for regulating the tightness of chain, being contained in behind the four-wheel beach buggy adjusting screw(rod) on the chain stay respectively by two finishes, by adjusting two nuts on the adjusting screw(rod), pull back sprocket shaft and realize the tensioning degree adjustment of chain, but be difficult to guarantee a left side like this, the screw rod regulating degree of right both sides is identical, not only make efficiency of assembling lower greatly because of regulating difficulty, and assembling or use easily make hind axle and back chain stay line of centers out of plumb when regulating, make hind axle produce deflection, cause with engine output shaft not parallelly, influence the stable of chain, transmission swimmingly.
Summary of the invention
The object of the present invention is to provide a kind of easy to use, can guarantee the chain regulator of the four-wheeled that hind axle is vertical with back chain stay line of centers, and can make things convenient for the assembling and the maintenance of four-wheeled.
The chain regulator of four-wheeled of the present invention, comprise back chain stay and left and right rear-axle casing with left and right prong, be provided with axle sleeve in the left and right rear-axle casing, hind axle by bearing installation in axle sleeve, the axle sleeve periphery has adapter plate and the circular bulge loop of hoop, the axle center of circular bulge loop is with the axis parallel of axle sleeve but do not overlap, circular bulge loop is concentric with the axle center of adapter plate, bulge loop partly is inserted in the prong of back chain stay, circle is evenly equipped with a plurality of mounting holes on the adapter plate, and adapter plate is by being bolted on the chain stay of back.
The preferred number of described mounting hole is 6, differs 60 degree angles between the adjacent mounting hole.
Circular bulge loop of described adapter plate and described hoop and axle sleeve can be structure as a whole, so that it is more firm and compact.
For the ease of fixed type bearing, described axle sleeve endoporus one end diameter diminishes, and forms a baffle ring of being convenient to fixed type bearing.
For the ease of the weight of rotation and minimizing adapter plate, described adapter plate outer rim can be evenly equipped with the arc tooth.
The quantity of described arc tooth is identical with mounting hole, and described mounting hole can be positioned at arc tooth place.
The sleeve length of described right back axle housing is greater than the sleeve length of left back axle housing.
The chain regulator of this four-wheeled is adjusted the device of sprocket wheel and is compared with respect to existing employing screw rod, have following advantage:
(1) easy to use, when pine or tension appearred in chain, unclamp the bolt that left and right rear-axle casing links to each other with the back chain stay respectively, rotate rear-axle casing simultaneously with identical hand of rotation, make it to turn over angle same, just can regulate the tightness of chain easily, and can guarantee that hind axle is parallel with engine output shaft, and chain stay line of centers and hind axle axis normal, the assurance hind axle can not produce and deflect, and maintenance is very convenient in feasible assembling and the use.
(2) compact conformation does not need adjusting screw(rod).
(3) because left and right rear-axle casing fixes by many bolts and back chain stay respectively, avoided stressed and concentrated, stress performance is good; Then be stressed in the prior art by screw rod and nut.
(4) safe, concentrate owing to avoid stressed, stressed even, improved safety performance greatly.
(5) good stability can not need to adjust in the long period after adjusting again.
Description of drawings
Fig. 1 is the chain regulator structural representation of four-wheeled of the present invention;
Fig. 2 is the cutaway view of left and right rear-axle casing;
Fig. 3 is the right elevation of left back axle housing shown in Figure 2.
The specific embodiment
Be described further below in conjunction with the chain regulator of the drawings and specific embodiments, to help understanding content of the present invention four-wheeled of the present invention.
Extremely shown in Figure 3 in conjunction with Fig. 1, left back axle housing 2 and right back axle housing 2 ' in each rear-axle casing comprise an axle sleeve 21, axle sleeve 21 is by bearing 3,3 ' be contained on the hind axle 5, axle sleeve 21 peripheries have adapter plate 22 and circular eccentric bulge loop 23, as shown in Figure 3, the axle center of circular bulge loop 23 is with the axis parallel of axle sleeve 21 but do not overlap, the formation eccentric structure, and circular bulge loop 23 is concentric with the axle center of adapter plate 22; Be evenly equipped with 6 mounting holes 24 on the adapter plate 22, angle is 60 degree angles between the adjacent mounting hole, it is on the circumference in the center of circle that all mounting holes 24 are positioned at an axle center with adapter plate 22, adapter plate 22 is fixed together by the prong structure of chain stay 1 behind mounting hole three bolts of 23 usefulness (omitting among the figure) and the four-wheeled, circular 23 of bulge loops just in time are inserted in the prong of back chain stay, three bolts are triangular arranged, promptly every the bolt that is equipped with of a mounting hole 24.By sprocket wheel disc brake seat 6 be installed on the hind axle 5 sprocket wheel 4 left and right rear-axle casing 2,2 ' between.
As shown in Figure 2, in the present embodiment, adapter plate 22 is structure as a whole with circular bulge loop 23, and is welded on the axle sleeve 21, makes it solid, compact.The outside end diameter of the axis hole of axle sleeve 21 is less, forms a baffle ring structure, so that fixed type bearing 3,3 '.Right back axle housing 2 ' sleeve length greater than the sleeve length of left back axle housing 2.
As shown in Figure 3, be evenly equipped with the position that 25,6 mounting holes 24 of 6 arc teeth are positioned at the arc tooth on adapter plate 22 neighborings, an effect of arc tooth 25 is to be convenient to rotate rear-axle casing with hand or instrument, and can reduce the weight of rear-axle casing.
When rotating simultaneously left and right rear-axle casing 2,2 ' time with same direction, because axle sleeve 21 is relative eccentric with the annular arrangement bulge loop 23 on the rear-axle casing, make annular arrangement bulge loop 23 when back chain stay 1 rotates, the axle center of axle sleeve changes with respect to the relative position of the line between the center of circle of the left and right prong of back chain stay, the axial line of hind axle 5 is moved forward or backward with respect to the back chain stay, and then the tightness of chain is conditioned.Because of each left and right rear-axle casing 2,2 ' time of rotating all is to rotate 60 degree angles (when not being 6 as the quantity of mounting hole, then its angle no longer is 60 degree) or its integral multiple, the line of centers that guarantees the back chain stay is vertical with hind axle 5 all the time, and hind axle 5 can not produce and deflect.
During preferable mode, in rotation 2,2 ' one weeks of rear-axle casing, the variation of chain tightness just is the length of a chain link, and rear-axle casing needn't be done too hugely like this, the rear chain pretension length out of reach requirement if rotate a circle can be adjusted by the mode of increase and decrease chain link.
