Abstract
The utility model discloses a chain-driven chain wheel of a motor vehicle, which is mainly composed of two half wheels. A left half wheel (1) and a right half wheel (2) are movably connected through an arc bulge (3) and an arc groove (4). The left half wheel (1) and the right half wheel (2) are fastened by a fastening sheet (6). The chain-driven chain wheel of a motor vehicle has the advantages that the stress of the chain-driven chain wheel of a motor vehicle is enhanced, and the service life of the chain-driven chain wheel of a motor vehicle is extended.
Description
Technical field
The utility model relates to a kind of drive sprocket, and particularly a kind of chain-driven Motor Vehicle sprocket wheel is a kind of Motor Vehicle differential mechanism back axle sprocket wheel particularly.
Background technique
In the prior art, chain-driven Motor Vehicle, especially motor tricycle, its differential mechanism sprocket wheel is to be sleeved in the middle of back axle two-semiaxle and the differential carrier.This sprocket wheel is a vulnerable part, needs often to change.And because the integral structure of sprocket wheel own, the sprocket wheel centripetal-stress is poor, causes its easy-rupturing in use, reduces the working life of sprocket wheel.
Summary of the invention
The purpose of the utility model is to provide a kind of improved sprocket wheel, and it has overcome the above-mentioned deficiency of prior art, has strengthened the sprocket wheel centripetal-stress, has increased its anti-crack ability, has prolonged its working life.
For reaching above-mentioned purpose, the technological scheme that the utility model is taked is:
The utility model is mainly taken turns by two and half and is formed, and the two halves wheel is by the arcuation projection and the arcuation groove is movable connects, and becomes a complete sprocket wheel, and for the purpose of firmly, the two halves wheel is fixed by removable fastening structure such as fastening sheet.
The utility model is taked above-mentioned this structure, has following beneficial effect:
1, because a complete sprocket wheel is taken turns by two and half and formed, two and half take turns and have arcuation projection and arcuation groove respectively, have strengthened the sprocket wheel centripetal-stress, have increased its anti-crack ability, have prolonged its working life.
2, owing to removable fastening structure on the sprocket wheel, further increase its anti-crack ability, prolonged its working life.
Embodiment
Embodiment: a kind of motor tricycle differential mechanism sprocket wheel as shown in Figure 1, comprise a left side partly take turns 1 with the right side partly take turns 2, at the two joint, a left side partly takes turns 1 arcuation projection 3, and the right side partly takes turns 2 has arcuation groove 4,4 grooves corresponding with arcuation projection 3, there is screw 5 both sides in two halves wheel connection place, fastening sheet 6 is an elongated sheets, and its two ends have circular hole relative with screw 5, and fastening sheet 6 is taken turns fastening by bolt 7 with two and half.
During installation, two and half arcuation projectioies 3 of taking turns and arcuation groove 4 are coincide, and fastening sheet 6 is fixing; During dismounting, two and half arcuations projectioies of taking turns 3 and arcuation groove 4 are broken away from, and fastening sheet unloaded get final product.
Claims (2)
1, chain-driven Motor Vehicle differential mechanism back axle sprocket wheel is characterized in that: it is mainly taken turns by two and half and forms, and a left side half wheel (1) is by arcuation projection (3) with right half wheel (2) and arcuation groove (4) is movable connects; A left side half wheel (1) and right half wheel (2) are in addition fastening by fastening sheet (6).
2, chain-driven Motor Vehicle differential mechanism back axle sprocket wheel according to claim 1 is characterized in that: there is screw (5) both sides in two halves wheel connection place; Fastening sheet (6) is an elongated sheets, and its two ends have circular hole relative with screw (5), and fastening sheet (6) is taken turns fastening by bolt (7) with two and half.
