Abstract
The utility model relates to a reversing mechanism for a motor tricycle, which is mainly composed of a driven gear which is driven by a main driving wheel of an engine and can slide in an axial direction and a first and a second intermediate gears which are positioned between the driven gear and a rear axle gear of a motor tricycle, wherein, the first intermediate gear is engaged with the second intermediate gear and the rear axle gear all the time, the driven gear can be respectively engaged with the first and the second intermediate gears by a shifting fork and an operating mechanism thereof. When the driven gear is engaged with the first intermediate gear, the rear axle gear rotates in a positive rotation, and the motor tricycle moves forwards; when the driven gear is engaged with the second intermediate gear, the rear axle gear rotates in a reverse direction, and the motor tricycle moves backwards.
Description
The utility model belongs to the driving device of self-propelled vehicle, is a kind of reverse gear of motor-tricycle.
The motor-tricycle of present motor-tricycle, particularly carrying does not all have reverse gear.Its type of drive is that the output chain gear of driving engine directly drives the back axle sprocket wheel through chain, thereby can only advance, and can not retreat.During if will move backward, chaufeur must be got off to pusher, and promptly effort is convenient again.And under the situation that city traffic relatively crowds at present, often need reversing again.
The purpose of this utility model provides a kind of reverse gear of motor-tricycle.
The solution that realizes the utility model purpose is: that the reverse gear of the motor-tricycle that is provided is driven by the driving engine main drive wheel and in axial sliding driven gear, be positioned at behind this driven gear and the motor bike first, second intermediate gear between axle gear and the shift fork and the steering unit thereof of this driven gear and form.Wherein first intermediate gear all the time with second intermediate gear and back axle gear mesh, aforementioned driven gear meshes with first or second intermediate gear respectively by shift fork and steering unit thereof.When the engagement of aforesaid driven gear and first intermediate gear, and when throwing off with second intermediate gear, the driving engine main drive wheel drives afterwards axle gear by the driven gear and first intermediate gear just to be changeed, and motor bike advances.When throwing off when the engagement of driven gear and second intermediate gear and with first intermediate gear, main drive wheel drives the back axle gear by driven gear, second intermediate gear and first intermediate gear successively and reverses, and motor bike retreats.
The utility model utilizes a slip driven gear and two intermediate gears to be combined into forward and backward mechanism, thereby compact conformation, volume are little, can be installed between driving engine and the back axle, make motor bike have car-backing function, and don't change other structures of motor bike.In addition, the manipulation of this mechanism also relatively flexibly.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is that the A-B-C of Fig. 1 launches scheme drawing.
Fig. 3 is that the D-E-B-C of Fig. 1 launches scheme drawing.
As shown in Figure 1: the main drive sprocket 1 of driving engine mouth drives sprocket wheel 3 by chain 2.Driven gear 4 is contained on the same castellated shaft 5 with sprocket wheel 3.Second intermediate gear 6 is dual gears, its middle gear 6
aAll the time with 7 engagements of first intermediate gear, gear 6
bCan mesh with driven gear 4.When driven gear 4 along castellated shaft to front slide, driven gear 4 and 7 engagements of first intermediate gear, and with gear 6
bThrow off.The state of this moment is as shown in Figure 2: driven gear 4 is just changeing back axle gear 8 by first intermediate gear 7, the idle running of second intermediate gear 6.When driven gear 4 slides backward, driven gear 4 and gear 6
bEngagement, and throw off with first intermediate gear 7.State as shown in Figure 3 at this moment: driven gear 4 is by gear 6
b, 6
a, first intermediate gear 7 drives 18 counter-rotatings of back axle gear, motor bike retreats.The slip of driven gear 4 is realized by shift fork 9 and steering unit 10 thereof.Steering unit 10 is made up of stretcher 11, retracing spring 12, pull bar 13 and pivoted arm 14.Step on stretcher 11, pull bar 13 reaches, pivoted arm 14 drives shift fork 9 backs to be changeed, and driven gear 4 backs are sliding, with gear 6
bEngagement retreats motor bike.Above-mentioned each gear all is contained in the casing 16.
Claims (1)
1, a kind of reverse gear of motor-tricycle, that it is characterized in that driving and driven gear (4) in axial sliding by driving engine main drive wheel (1), be positioned at first between axle gear (8) behind this driven gear (4) and the motor bike, second intermediate gear (7,6) and the shift fork (9) of this driven gear (4) and steering unit (10) thereof form, wherein first intermediate gear (7) all the time with second intermediate gear (6) and back axle gear (8) engagement, aforementioned driven gear (4) by shift fork (9) and steering unit (10) thereof respectively with first or second intermediate gear (7,6) engagement.
