Description

The high low speed gun stocks of a kind of motor-tricycle

Technical field

The utility model relates to a kind of motor tricycle driving mechanism, the high low speed gun stocks of especially a kind of motor-tricycle.

Background technique

As a kind of means of transportation, motor tricycle is low with its price, easy to usely be widely used in vast town and country, but existing motor tricycle all is not provided with the reversing driving mechanism, can only advance, and can not retreat, during reversing, the driver must get off, and personnel selection is tried hard to recommend motor vehicle and moveed backward, and is very inconvenient.The someone had invented the tricycle reverse gear afterwards, though solved the reversing problem of tricycle, during operation, owing to can not realize that high and low speed changes, can't solve the existing ubiquitous high load with small power problem of tricycle.

The model utility content

The purpose of this utility model provides a kind of novel structure, the high low speed gun stocks of motor-tricycle easy to use.

The technical solution of the utility model is: the high low speed gun stocks of a kind of motor-tricycle, comprise motor and back axle, on the crossbeam between motor and the back axle, be provided with four high and low speed speed casees, sprocket wheel and high to low gear duplicate gear before wherein on the I axle, being equipped with, preceding sprocket wheel is connected with the motor output terminal by chain, be provided with circular groove on one of them gear of high to low gear duplicate gear, this circular groove is connected with drive link on the high low speed handle by the high to low gear shift fork; On the II axle, duplicate gear is housed, two gears are housed on the III axle, afterwards sprocket wheel and ahead running gear are housed on the IV axle, be provided with circular groove on the ahead running gear, this circular groove is connected with drive link on positive and negative driver's handle by shift fork, and back sprocket wheel is connected with the back axle sprocket wheel by chain.

High to low gear duplicate gear on the I axle is made up of a gearwheel and a small gear, and the duplicate gear on the II axle is made up of a small gear and a gearwheel.

Advantage of the present utility model:

1, in reversing or ahead running, also can realize height velocity modulation speed, the using scope of tricycle is expanded, solve existing tricycle high load with small power problem simultaneously.

2, energy saving, the working life of prolongation tricycle.

Embodiment

Structure of the present utility model is as depicted in figs. 1 and 2: comprise fuel tank 1, vehicle seat 2, high low speed handle 3, positive and negative driver's handle 4, railway carriage 5, rear chain 7, rear wheel 8, back sprocket wheel 9, tensioner bolt 10, carriage 11, crossbeam 12, location silk 31,32, motor 15 and back axle 23, on the crossbeam between motor and the back axle 12, be provided with four high and low speed speed casees 13, sprocket wheel 13-2 and high to low gear duplicate gear 19 before wherein on I axle 13-3, being equipped with, preceding sprocket wheel is connected with motor output terminal 16 by chain 14, be provided with circular groove 29 on one of them gear 19-1 of high to low gear duplicate gear, this circular groove is connected with drive link 21 on the high low speed handle 3 by high to low gear shift fork 22; On II axle 13-4, duplicate gear 18 is housed, two gears 27,28 are housed on III axle 13-5, afterwards sprocket wheel 9 and ahead running gear 26 are housed on IV axle 13-6, be provided with circular groove 26-1 on the ahead running gear, this circular groove is connected with drive link 24 on positive and negative driver's handle 4 by shift fork 25, and back sprocket wheel 9 passes through chain 7 and is connected with back axle sprocket wheel 30.High to low gear duplicate gear 19 on the I axle is made up of a gearwheel 19-1 (high gear) and a small gear 19-2 (low speed gear), and the duplicate gear 18 on the II axle is made up of a small gear 18-1 (high gear) and a gearwheel 18-2 (low speed gear).

Working procedure of the present utility model:

At a high speed along the car backing operation process: the power of motor 15 sends four preceding sprocket wheel 13-2 on the I axle outside the high and low speed speed case 13 casing 13-1 to by chain 14, high to low gear duplicate gear 19 on the I axle is by high and low shift drive link 21 pulling high and low shift forks 22, and fork reaches speed change (at a high speed) purpose by gearwheel 19-1 and the engagement of the small gear 18-1 on the II axle duplicate gear 18 on the 29 pulling high and low shift gears of the circular groove on the gearwheel 19-1 in the high to low gear duplicate gear.Combine with transition gear 27 or 28 on the III axle by the small gear 18-1 on the II axle then, make power send ahead running gear 26 on the IV axle to.Ahead running gear 26 is by positive and negative driver's handle 4, the pulling of ahead running drive link 24 reaches down suitable purpose with falling of annular groove 26-1 inserting on the ahead running gear 26 along fork 25, then by sprocket wheel behind the IV axle 9 by rear chain 7 power transmission to motor-tricycle back axle 23, the whole operation process is finished.
