Abstract
The utility model relates to a gear reversing device which more fits the motor tricycles. A pair of driving bevel gears are respectively provided with same axes in a shell body by bearings; a drive outputting axes is arranged on the shell body by bearings; one end of the drive outputting axes which extends into the shell body is provided with driven bevel gears; the driven bevel gears are frequently joggled with the two driving bevel gears. The driving bevel gears and the driving axes adopt the spline cooperation method and realize the rotating direction metathesis of the driving outputting axes by reciprocating gliding the main driving axes. The utility model is characterized in easy gearing, small gearing impact etc.
Description
The utility model relates to a kind of gear reversing device, is particularly suitable for motor-tricycle and uses.
The tradition motor-tricycle is that reverse gear is not set, and people can only make motor-tricycle realize reversing by manpower in actual use.Because the motor-tricycle own wt is big, frequent manual operation meeting brings user's inconvenience, and the people that therefore come in attempt to set up gear reversing device on motor-tricycle, realize the reversing of motor-tricycle by driving engine self power.The structure of representative type gear reversing device is: centre portion of engine power output shaft contact has the castellated shaft of spline, be with spline housing on the castellated shaft, a pair of drive bevel gear that can free turn on castellated shaft is set in opposite directions at the two ends of castellated shaft upper spline cover, drive bevel gear and driven wheel of differential constant-mesh, driven wheel of differential is in relation to power take-off shaft.The teeth of projection are arranged at the two ends of spline housing, on the end face that interrelates with spline condom end on the drive bevel gear, depression is arranged.Depression on teeth on the spline housing and drive bevel gear end face constitutes castellated structure.By shift fork spline housing is slided on castellated shaft, make spline housing realize castellated the cooperation, thereby realize the hand of rotation displacement of power take-off shaft with one of a pair of drive bevel gear.Though this kind gear reversing device has been realized the reversing of motor-tricycle, but there is following deficiency in this structure: because teeth on the spline housing and the depression on the drive bevel gear end face constitute castellated structure, if it is intermittently little that the teeth on the spline housing cooperate with the depression on the drive bevel gear end face, teeth on the spline housing just are difficult to enter the depression on the drive bevel gear end face, just exist the said extension of proverb not advance the phenomenon of shelves; If it is intermittently big that the teeth on the spline housing cooperate with depression on the drive bevel gear end face, though easy engage a gear, the impact that bring intermittence greatly is also very big, impacts excessive even can cause damage to the parts of motor-tricycle.In addition, the related number of parts of this kind structure is many, part complex-shaped, and difficulty of processing is also big.
The utility model will provide a kind of gear reversing device exactly, and it is easy to make it have an engage a gear, and engage a gear impacts little, and the characteristics of handling ease.
The purpose of this utility model is achieved in that a kind of gear reversing device, comprise a pair of drive bevel gear that is provided with in opposite directions and with the driven wheel of differential of drive bevel gear constant-mesh, driven wheel of differential is in relation to power take-off shaft, it is characterized in that: a pair of drive bevel gear is installed in the housing by the coaxial bearing line respectively in opposite directions, dynamic output shaft by bearing installation in housing, the end that power take-off shaft stretches in the housing is equipped with driven wheel of differential, driven wheel of differential and two drive bevel gear constant-meshes; In the axis hole of a pair of drive bevel gear spline is arranged, axis hole by a pair of drive bevel gear that is provided with in opposite directions is provided with main driving axle, main driving axle can reciprocatingly slide along axis, the spline that matches with spline in the drive bevel gear axis hole is arranged, the annular groove that matches with the shift shift fork in addition on the main driving axle on the main driving axle; End at main driving axle has spline, and is in relation to engine output shaft by spline housing.
Drive bevel gear of the present utility model and main driving axle have adopted the spline fitted mode, realize the hand of rotation displacement of power take-off shaft by the main driving axle that reciprocatingly slides.Because it is little that the spline fitted mode has in conjunction with the dead angle, bonding gap is little, therefore the utlity model has easy engage a gear and engage a gear and impacts characteristics such as little.
Below by embodiment the utility model is further described.
Fig. 1 is a kind of example structure scheme drawing of the utility model.
The basic structure of embodiment is: a pair of drive bevel gear 6,12 is installed in the housing 5 in opposite directions by bearing 1,13 coaxial lines respectively, dynamic output shaft 11 is installed on housing 5 by bearing 8, the end that power take-off shaft 11 stretches in the housing 5 is equipped with driven wheel of differential 7, driven wheel of differential 7 and two drive bevel gear 6,12 constant-meshes; In the axis hole of a pair of drive bevel gear 6,12 spline 10 is arranged, axis hole by a pair of drive bevel gear 6,12 that is provided with in opposite directions is provided with main driving axle 4, main driving axle 4 can reciprocatingly slide along axis, the spline 14 that matches with spline 10 in drive bevel gear 6,12 axis holes is arranged, the annular groove 3 that matches with the shift shift fork in addition on the main driving axle 4 on the main driving axle 4; End at main driving axle 4 has spline 9, and is in relation to engine output shaft 15 by spline housing 2.The working process of embodiment is such: under the effect of main driving axle 4 at shift fork, the spline 14 on the main driving axle 4 combines with the axis hole spline 10 of one of a pair of drive bevel gear 6,12, and 6,12 of another drive bevel gear are in free state.Engine output shaft 15 makes main driving axle 4 rotations by spline housing 2, finally makes power take-off shaft 11 rotate.Axially slide under the effect of main driving axle 4 at shift fork, the spline 14 on the main driving axle 4 is combined with the axis hole spline 10 of another drive bevel gear 6,12,6,12 of drive bevel gear that break away from combination are in free state.Engine output shaft 15 makes main driving axle 4 rotations by spline housing 2, finally makes power take-off shaft 11 rotate.This moment, hand of rotation and preceding a kind of state of power take-off shaft 11 were just the opposite.
