Abstract

The utility model relates to a motorcycle reverse differential gear which consists of a driving gear (1), a driven gear (3), a planetary gear cluster (4), a sun gear (5), a differential mechanism (6) and a reverse transmission fork sleeve (8); the planetary gear cluster (4) consists of three planetary gears which are fixed by a planetary gear retainer (10) and operate together; the reverse transmission fork sleeve (8) drives the planetary gear retainer (10) to be separately combined with the driven gear (3) or the reverse differential gear box (6). The utility model is provided with a compact structure and can realize functions of speed reduction, reverse gear and differential speed at the same time to transfer the power directly to the driving wheel without being driven by a chain or a middle transmission shaft.

Description

Motor bike reverse gear diff

(1), technical field

The utility model relates to a kind of motor bike reverse gear diff of compact conformation.

(2), background technology

In the prior art, independently reverse gear mechanism and box of tricks are housed generally on three-wheel or four-wheel motor cycle, its reverse gear is to realize by gear cluster or two-way finishing bevel gear cuter, and its shortcoming is that volume is bigger, and power needs chain or tween drive spindle to transmit.

(3), summary of the invention

Technical problem to be solved in the utility model is: reverse gear and box of tricks are combined, realize reverse gear with planetary wheel, it is made up of one group of planetary wheel and diff, realizes the reverse gear function by the locking planetary wheel.Compact conformation can be realized the power through-coupling of three-wheel or four-wheel motor cycle not needing chain or tween drive spindle, has overcome the shortcoming of traditional mechanism, can realize the compact Layout of three-wheel or four-wheel motor cycle.

The utility model is to adopt such technical scheme to realize, it is a kind of motor bike reverse gear diff, form by driving gear, driven gear, compound planet gear, sun tooth, box of tricks and reverse speed fork cover, wherein compound planet gear is made up of three planetary wheels, the fixing and running together by the planetary wheel retainer; The reverse speed fork cover drives planetary gear carrier and combines with driven tooth or reverse gear diff casing respectively.

(4) description of drawings

The utility model has following accompanying drawing:

Fig. 1, structural principle birds-eye view of the present utility model;

Fig. 2 is a structural principle lateral plan of the present utility model;

Fundamental diagram when Fig. 3 is the utility model reverse gear.

In the accompanying drawing: 1-driving gear, 2-engine output shaft, 3-driven gear, the resistance of 4--planetary wheel, 5-sun tooth, 6-box of tricks, 7-left half axle, 8-back fork cover, 9-right axle shaft, 10-planetary wheel retainer.

(5), the specific embodiment

Below in conjunction with accompanying drawing specific embodiments is described further:

Referring to accompanying drawing: the motor bike reverse gear diff among the figure is made up of driving gear 1, driven gear 3, compound planet gear 4, sun tooth 5, box of tricks 6 and reverse speed fork cover 8, wherein compound planet gear 4 is made up of three planetary wheels, by the 10 fixing and runnings together of planetary wheel retainer; Sun tooth 5 and flower wheel 3 or satellite gear engagement, box of tricks 6 is fixed on the sun tooth; Reverse speed fork cover 8 drives planetary gear carrier 10 and combines with driven tooth 3 or reverse gear diff casing 6 respectively.

Principle of work of the present utility model is such: generally speaking, planetary wheel retainer 10 is linked together by reverse speed fork cover 8 with driven gear 3, and

gear

3,4,5 can only be turned round synchronously in the same way.When motor bike advanced, power passed to driving gear 1 by engine shaft 2, passed to driven tooth 3 again.Because gear 3 is more much bigger than gear 1, can realize main deceleration.Gear 3 because diff is fixed on the sun tooth 5, so power just is assigned to left and right sides semiaxis 7 and 9 from gear 5 through diff 6, thereby drives motor bike by 5 runnings of gear cluster 4 driven gears.When outwards stirring dial sleeve 8, planetary gear carrier 10 and driven gear 3 are thrown off, and connect with tooth cover on being fixed on casing, planetary gear carrier 10 can not be rotated.Because planetary gear carrier 10 is fixed, make that each gear of compound planet gear 4 can only rotation, can not revolve round the sun.As shown in Figure 3, driving gear 2 clickwises, driven gear 3 left-hand revolutions, planetary wheel is fixed by tooth rest 10, can only the conter clockwise rotation under the drive of gear 3, thus drive sun wheel 5 clickwises, thereby realize the rotation opposite, reach the reverse gear function with working direction.

Claims

1, a kind of motor bike reverse gear diff, it is characterized in that: form by driving gear (1), driven gear (3), compound planet gear (4), sun tooth (5), box of tricks (6) and reverse speed fork cover (8), wherein compound planet gear (4) is made up of three planetary wheels, the fixing and running together by planetary wheel retainer (10); Reverse speed fork cover (8) drives planetary gear carrier (10) and combines with driven tooth (3) or reverse gear diff casing (6) respectively.

2, motor bike reverse gear diff according to claim 1 is characterized in that: sun tooth (5) and flower wheel (3) or satellite gear engagement, box of tricks (6) is fixed on the sun tooth (5).
