Abstract
The utility model relates to a reverse gear device for tricycles. An input shaft, a transmission shaft and an output shaft are arranged in a box body. An input chain wheel and two step-shaped gears whose small ends correspond to each other, are installed on the input shaft, and a shaft coupling gear is installed between the two gears. The shaft coupling gear and the small ends of the step-shaped gears are combined with combining sleeves with spaced inner teeth, the combining sleeves are connected with a reverse gear shifting rod shaft on which a gear shifting arm is installed through a shifting fork, and the shifting fork is sheathed on a shifting fork shaft with a spring. A transmission gear, a reverse gear and an output gear are installed on the output shaft. The utility model synthesizes the two stage transmission, the speed reduction and the reverse gear into a whole and has the advantages of convenient reversing process, large transfer twisting force and high safety.
Description
The utility model relates to a kind of reverse gear apparatus, especially is applicable to the three-wheel vehicle reverse gear apparatus on the positive three-wheel vehicle.
Positive three-wheel vehicle reverse gear apparatus is the deceleration direction reverser in the motorvehicle mechanical mechanism, because at present positive three-wheel vehicle is continued to use the motorcycle chain type of drive, and generally there is not the speed change direction reverser between from the driving engine to the back axle on the vehicle, reverse gear apparatus promptly is not installed, motor bike when reversing, need the chaufeur go-cart of getting off, therefore, vehicle backing carries out with manpower by chaufeur, so use inconvenient.
The purpose of this utility model provides a kind of three-wheel vehicle reverse gear apparatus, and it is installed between driving engine and the back axle, realizes just commentaries on classics, counter-rotating and the decelerated movement of three-wheel vehicle by engine power and chain-driving, thereby increases the gear reversing function of three-wheel vehicle.
Concrete scheme of the present utility model is: input shaft, transmission shaft, output shaft are installed in casing; Wherein one of input shaft stretches out casing input sprocket is installed outward, be positioned on the input shaft of casing and be set with two stepped gears, the small end of two stepped gears is corresponding, between two gears joint shaft gear is housed, small end at joint shaft gear and stepped gear is combined with the combined cover of interband every internal tooth, combined cover is connected with the shift lever axis that reverses gear through shift fork, on the shift lever axis that reverses gear gear arm is housed, and shift fork is contained on the declutch shift shaft that spring is housed by the shift fork sheathed catheter; Driven gear is housed on transmission shaft; Transmission gear and reverse gear are installed on output shaft, between two gears spacer are housed, output shaft stretches out casing and adorns output gear outward; Reverse gear on the output shaft is greater than transmission gear and greater than the stepped gear on the input shaft.
Adopt the such scheme compact conformation, diverse in function can collect the secondary transmission, slows down, reversing gear is one, and commutation is convenient, and it is big, safe and reliable to transmit torsion.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
By above-mentioned accompanying drawing as can be known: the utility model mainly is made up of input sprocket 1, input shaft 2, gear arm 3, stepped gear 4, combined cover 5, joint shaft gear 6, bearing 7, stifled plug cock 8, driven gear 9, transmission shaft 10, reverse gear 11, output chain gear 12, output shaft 13, bolt 14, spacer 15, casing 16, transmission gear 17, declutch shift shaft 18, shift fork conduit 19, spring 20, shift fork 21, the shift lever axis 22 that reverses gear.Its architectural feature is: input shaft 2, transmission shaft 10, output shaft 13 are installed in casing 16; Wherein 2 one of input shafts stretch out the casing 16 outer input sprockets 1 of installing, be positioned on the input shaft 2 of casing 16 and be set with two stepped gears 4, the small end of two stepped gears 4 is corresponding, joint shaft gear 6 is housed between two gears, small end at joint shaft gear 6 and stepped gear 4 is combined with the combined cover 5 of interband every internal tooth, combined cover 5 is connected with the shift lever axis 22 that reverses gear through shift fork 21, on the shift lever axis 22 that reverses gear gear arm 3 is housed, and shift fork 21 is sleeved on the declutch shift shaft 18 that spring 20 is housed by shift fork conduit 19; Driven gear 9 is housed on transmission shaft 10; Spacer 15 is housed being equipped with on the output shaft 13 between transmission gear 17 and reverse gear 11, two gears, output shaft 13 stretches out casing 16 outer dress output gears 12; Reverse gear 11 on the output shaft 13 is greater than transmission gear 17 and greater than the stepped gear on the input shaft 24.
As can be seen from Figure 2: casing 16 is made up of left case lid and right case lid, and input shaft 2, transmission shaft 10 and output shaft 13 are installed on the casing 16 by bearing 7, at the not end plug of input shaft 2 and transmission shaft 10 stifled plug cock 8 is arranged.
Input sprocket 1 of the present utility model is connected with the driving engine output chain gear through chain, and output gear 12 of the present utility model is connected through the sprocket wheel of chain with the car back axle; In a single day driving engine starts the utility model and just enters work:
When combined cover 5 was in the left side, the interval internal tooth of combined cover 5 combined with the spaced teeth of left side stepped gear 4, and the left side stepped gear rotates, and passed to the gear on transmission shaft 10, the output shaft 13 successively, and the output chain gear 12 on the output shaft 13 is rotated in the forward thereupon.Stir gear arm 3 during reversing, the shift lever axis 22 that reverses gear just rotates and drives shift fork 21 and combined cover 5 moves right, and combined cover 5 combines with the spaced teeth of right side stepped gear 4; Because right side stepped gear 4 directly meshes with the reverse gear 11 of output shaft 13, so output chain gear 12 contrarotations, thereby reach the purpose of the reversing of slowing down.In case decontrol gear arm 3, gear arm 3 and shift fork 21 are got back to original position rapidly under the effect of spring 20, combined cover 5 is in positive transposition again and puts (left side), and rotate input sprocket 1 this moment, and output chain gear 12 is just changeing.
