Abstract
The utility model discloses a suspended structure for rear wheel transmission of four-wheel motor, comprising a chainwheel shaft and a shock absorber, characterized in that the chainwheel shaft connects with one end of a ball-cage transmission shaft, a shaft with spindles of another end of the ball-cage transmission shaft goes through a shaft bearing hole of a bearing frame and extends out; the bearing stand connects hingedly with one end of an upper cradle and one end of a lower cradle respectively, another ends of the upper cradle and the lower cradles are respectively hinged to the vehicle frame; the upper cradle is hinged to lower end of the shock absorber, the upper end of which is hinged to the vehicle frame. The utility model is able to realize the flexible transmission of rear wheels, mitigating the impact of rear axle in motion state, enhancing the jumping performance and reducing the shock produced by the motor; the utility model is also able to adjust the left and right rear wheels to make them contact with the ground simultaneously, increasing the driving force thereof and making the drive more stable and comfortable.
Description
Technical field
The utility model relates to the trailing wheel transmission field of four-wheel motor cycle, the suspended structure of particularly a kind of four-wheel motor back wheels of vehicle transmission.
Background technology
Traditional four-wheel motor back wheels of vehicle generally is to be connected transferring power by a major axis that is installed in the band chain wheel on the back axle with rear wheel hub, major axis is supported in rear overhang and hangs up, the back hang and vehicle frame between mounting shock absorber, rely on the retraction stroke of bumper to reduce the vibrations that cause because of Uneven road.Because the retraction stroke of the bumper of trailing wheel is shorter, and the suspension of existing back only reduces vibrations by bumper, makes four-wheel motor cycle vibrations under steam bigger, the traveling comfort that influence is taken.Again because the sprocket wheel major axis is to hang up at rear overhang by bearing fixing, the sprocket wheel major axis is connected by chain-driving with driving engine, the jerk power that trailing wheel is subjected to directly acts on the driving engine by chain, and driving engine is caused very big impact, causes the vibrations of four-wheel motor cycle to increase thus.
Summary of the invention
The purpose of this utility model provides the suspended structure of a kind of four-wheel motor back wheels of vehicle transmission, it adopts ball cage transmission shaft and upper and lower reel cage to hang, and realizes the flexible transmission of trailing wheel, the impact when alleviating the back axle state of kinematic motion, strengthen performance enthusiastically, reduce the vibrations that driving engine produces; Also can adjust left and right sides trailing wheel kiss the earth simultaneously, increase the trailing wheel driving dynamics, make driving more stable, comfortable.
The purpose of this utility model is achieved in that and comprises sprocket shaft, bumper, described sprocket shaft is connected with ball cage transmission shaft one end, the bearing hole that the axle of the wounded in the battle key of the ball cage transmission shaft other end passes in the bearing support is overhanging, bearing support is hinged with an end of last reel cage, bottom cradle respectively, the other end of last reel cage, bottom cradle is articulated in vehicle frame respectively, the lower end of last reel cage and bumper is hinged, and the upper end of bumper is articulated in vehicle frame.
Owing to adopted such scheme, made to the utlity model has following advantage:
The sprocket shaft that transmits engine power is connected with rear wheel hub by ball cage transmission shaft, makes the trailing wheel transmission form flexible transmission, can reduce the trailing wheel jerk and conduct vibrations to driving engine.
Adopting upper and lower reel cage to hang combines with ball cage transmission shaft, the jerk that makes trailing wheel is by buffer of damper the time, upper and lower reel cage hangs with ball cage transmission shaft also can alleviate a part of jerk power, reduces the vibrations that vehicle frame is given in conduction, improves damping effect.Also can make left and right sides trailing wheel on rough road surface, obtain adjusting simultaneously, left and right sides trailing wheel can be remained with ground contact, increase the trailing wheel driving dynamics, make driving more stable, comfortable.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The fractionation scheme drawing that Fig. 2 connects to ground for the utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2, describedly be connected with ball cage transmission shaft 5 one end splines by chain-drive sprocket shaft 6 with driving engine, axle 10 bearing holes that pass in the bearing support 3 of the wounded in the battle key of ball cage transmission shaft 5 other ends are overhanging, are used for being connected with the rear wheel hub spline.The right and left of described bearing support 3 is respectively the arm that extends to the inside of symmetry, is respectively equipped with lower shaft hole on the arm.Bearing support 3 is hinged with an end of last reel cage 1, bottom cradle 2 respectively, described upward reel cage 1, bottom cradle 2 are " A " font reel cage that steel pipe is welded into, its small end is welded with pipe spreader c, pipe spreader c is hinged by bolt and two axis holes above the bearing support 3, two pipe ends of its big end are welded with pipe spreader a, b respectively, two pipe spreader a of last reel cage 1 are respectively by the upper journal of bolted splice in vehicle frame 7 crossbeams, and two pipe spreader b of bottom cradle 2 are respectively by the journal stirrup of bolted splice in vehicle frame 7 cross sills.Described going up is welded with the bearing 8 that connects bumper on the reel cage 1, the journal stirrup 9 on the bearing is hinged by the lower end of bolt and bumper 4, and the upper end of bumper 4 is articulated in the journal stirrup on the vehicle frame 7.
The utility model adopts left-right symmetric to be installed on the vehicle frame, when four-wheel motor cycle when rough road conditions are exercised, its upper and lower reel cage and the combination of ball cage transmission shaft, can improve damping effect, can also keep simultaneously left and right sides trailing wheel to contact with ground simultaneously, increase the trailing wheel driving dynamics, make driving more stable, comfortable.
