Abstract
The utility model discloses a four-wheel beach cycle two-stage drive device, and the utility model belongs to the speed variator applied for the minitype powered maneuver vehicle. The four-wheel beach cycle two-stage drive device is arranged between engine output carrier wheels and rear shaft carrier wheels. The four-wheel beach cycle two-stage drive device is characterized in that the four-wheel beach cycle two-stage drive device is fixed on a shaft sleeve by two carrier wheels with different diameters in size. The shaft sleeve is connected to a vehicle frame through a bearing. The four-wheel beach cycle two-stage drive device converts the original one-stage drive into the two-stage drive, and one expanded form speed reducer system. Whereas compared with the traditionary gear engagement type speed reducer, because the four-wheel beach cycle two-stage drive device has not the constraint that two gear wheels must be engaged, the four-wheel beach cycle two-stage drive device has very large freedom degree. The four-wheel beach cycle two-stage drive device has simple structure, convenient operation, easy processing, low cost and convenient lubrication.
Description
Technical field
The utility model relates to the transmission system of using on a kind of minitype motivation self-propelled vehicle, especially four-wheel beach buggy secondary transmission device.
Background technology
In the past-sale service process of motor bike production and motor bike, distinct issues that run into are exactly owing to having only the one-level transmission to cause motorcycle speed excessive, and moment of torsion is slightly inadequate by contrast.The method of traditional increase moment of torsion is to utilize the gear-engaged type change-speed box, slows down to increase to turn round.But complex structure, the cost height, oad is restricted.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that prior art exists, and a kind of simple in structure, simple to operate, handling ease is provided, and slows down to increase and turns round the four-wheel beach buggy secondary transmission device that is easy to realize.
The technical solution of the utility model is: this four-wheel beach buggy secondary transmission device, it is arranged between driving engine output chain gear and the rear axle sprocket wheel, it is characterized in that it is fixed on the axle sleeve by two sprocket wheels that diameter does not wait, axle sleeve is connected on the vehicle frame by bearing.
Be that big minor sprocket and axle sleeve all are connected by six uniform bolted each side, differ 30 ° of angles between the adjacent bolt.In addition, big minor sprocket and axle sleeve employing bolt also are feasible by the connection mode of their concentric holes.
The beneficial effects of the utility model are: on the basis of original one-level transmission, add two sprocket wheels not of uniform size that are fixed together, simultaneously original one-level transmission is become the two-stage transmission, this is just from the retarder system of an expansion equation of formal formation, but compare with traditional gear-engaged type retarder, under square one, have unrivaled preceence again, because it had not both had two gears to retrain by ingear, thereby very big degree of freedom is arranged on oad.In addition, in appropriate circumstances, this four-wheel beach buggy secondary transmission device can utilize conversely and become speed increaser.This four-wheel beach buggy secondary transmission device is simple in structure, easy to operate, handling ease, and cost is low, and is lubricated convenient.
Description of drawings
Fig. 1 is a part sectional view of the present utility model;
Fig. 2 is the utility model and driving engine and rear axle connection location graph of a relation.
Among the figure: 1 hinge wheel, 2 minor sprockets, 3 axle sleeves, 4 bearings, 5` bolt, 6 engine sprockets, 7 rear axle sprocket wheels.
The specific embodiment
As Fig. 1, two hinge wheels 1, the minor sprocket 2 that it is not waited by diameter is cemented on the same axle sleeve 3, and the bind mode of axle sleeve 3 and axle is that the rolling of using antifriction-bearing box 4 is connected.On the material of using, the 40Cr that large and small sprocket wheel has adopted is economical and practical, hard wear resistant has certain toughness again, and axle sleeve 3 adopts abrasion resistant cast iron ZT230-450.Bearing 4 adopts gauge member.In order to guarantee the bonded assembly reliability, each side adopts 6 connection modes that the M8 bolt is uniform, establishes through hole on sprocket wheel, and the axle sleeve endoporus is provided with negative thread.In order to prevent bolt looseness, it is spacing with two one group of nut to use three floor clips.
As Fig. 2,
Engine sprocket 6 is connected the hinge wheel 1 of four-wheel beach buggy secondary transmission device by chain, minor sprocket 2 by four-wheel beach buggy secondary transmission device connects rear axle sprocket wheel 7 again, like this, no matter how many transmitting ratios under the one-level transmission has, after having increased four-wheel beach buggy secondary transmission device, (bull wheel of four-wheel beach buggy secondary transmission device and the ratio of number of teeth of steamboat are N) be not when considering the degradation of energy of mechanism, the output torque of mechanism also increases N doubly accordingly, and output speed reduces N doubly.Certainly, according to actual conditions and related standards, big or small teeth number of sprocket ratio can suitably be adjusted in the four-wheel beach buggy secondary transmission device.
The utility model four-wheel beach buggy secondary transmission device can be applied on the chain drive vehicles such as boosted vehicle, motor bike widely.
Claims (2)
1, four-wheel beach buggy secondary transmission device, it is arranged between driving engine output chain gear and the rear axle sprocket wheel, it is characterized in that it is fixed on the axle sleeve by two sprocket wheels that diameter does not wait, and axle sleeve is connected on the vehicle frame by bearing.
2, four-wheel beach buggy secondary transmission device according to claim 1 is characterized in that large and small sprocket wheel all is connected by each side uniform six bolted with axle sleeve, differs 30 ° of angles between the adjacent bolt.
