Abstract
The utility model discloses a gearbox, in particular a motor vehicle gearbox, which comprises an input shaft, a drive shaft, an output shaft and a controlling handle; a clutch is arranged between the input shaft and the drive shaft; a transmission gear is arranged between the drive shaft and the output shaft; the utility model is characterized in that: the transmission gear consists of a bull wheel, a middle wheel and a small wheel which are arranged on the same plane concentrically and movably connected with each other; gear teeth of the bull wheel, the middle wheel and the small wheel face to the drive shaft; two gears arranged in tandem and respectively facing to the transmission gear are fixed on the drive shaft. The motor vehicle gearbox reduces the quantity of the gears greatly; the gear and the clutch can be integrally controlled by the control handle so as to simplify the operating steps; the control handle can be operated in the same line from a reverse gear to a low gear, a middle gear and a high gear, and the operation is convenient.
Description
(1) technical field
The utility model relates to a kind of gearbox, particularly a kind of motor vehicle gearbox.
(2) background technique
Present motor vehicle gearbox, particularly agricultural motor tricycle car gearbox is generally four gears, three forward gears, one reverse gear, even so few gear also needs a lot of gear engagement, cooperation each other is inharmonious, be inconvenient to install, the casing heaviness, volume is big, the manufacture cost height.
(3) summary of the invention
The utility model provides the motor vehicle gearbox that a kind of convenience is installed, casing is light, volume is little in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of motor vehicle gearbox, comprise input shaft, transmission shaft, output shaft, Joystick, it between described input shaft, the transmission shaft clutch, be speed change gear between described transmission shaft, the output shaft, its special way is: described speed change gear is made up of three wheels of bull wheel, middle wheel, steamboat of concentricity isoplanar, flexible connection each other; The gear teeth of bull wheel, middle wheel, three wheels of steamboat are towards transmission shaft, are fixed with respectively tandem two gears towards speed change gear on the transmission shaft.
Motor vehicle gearbox of the present utility model, described Joystick is connected with the shift fork of solenoidoperated cluthes.The gear ratio of described bull wheel, middle wheel, steamboat is 80: 40: 20.
The utility model has significantly reduced gear quantity, and whole gear and the clutch handled of Joystick, has simplified operating procedure; And Joystick from reverse gear, low gear, line operation of retaining, high gear, easy to operate.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model speed change gear.
Among the figure, 1 input shaft, 2 transmission shafts, 3 output shafts, 4 Joysticks, 5 clutches, 6 bull wheels, wheel in 7,8 steamboats, 9 forward gears, 10 backward gears, 11 shift forks.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises input shaft 1, transmission shaft 2, output shaft 3, Joystick 4, Joystick 4 be positioned at output shaft 3 directly over, be clutch 5 between input shaft 1, the transmission shaft 2, be speed change gear between transmission shaft 2, the output shaft 3, speed change gear is made up of 8 three wheels of bull wheel 6, middle wheel 7, steamboat of concentricity isoplanar, flexible connection each other, and the number of teeth of bull wheel 6, middle wheel 7, steamboat 8 is respectively 80,40,20; The gear teeth of bull wheel 6, middle wheel 7,8 three wheels of steamboat are towards transmission shaft 2, are fixed with on the transmission shaft 2 respectively towards tandem two gears of speed change gear, and the front end gear is a forward gear 9, and the rear end gear is a backward gear 10; Joystick 4 is connected with the shift fork 11 of solenoidoperated cluthes 5.
In use, Joystick from reverse gear, low gear, line operation of retaining, high gear, promote Joystick 4 backward, backward gear 10 moves forward, and makes backward gear 10 and bull wheel 6 engagements, clutch combination simultaneously, input shaft 1 drives transmission shaft 2, backward gear 10, and then drive bull wheel 6 counter-rotation, and Motor Vehicle is retreated, this moment is for reversing gear; Promote Joystick 4 forward, forward gear 9 moves backward, makes forward gear 9 and bull wheel 6 engagements, clutch combination simultaneously, and input shaft 1 drives transmission shaft 2, forward gear 9, and then drives the rotation of bull wheel 6 postive directions, makes the Motor Vehicle low-speed forward, and be low gear this moment; Then promote Joystick 4 forward, forward gear 9 moves backward, makes forward gear 9 and middle wheel 7 engagements, clutch combination simultaneously, input shaft 1 drives transmission shaft 2, forward gear 9, and then wheel 7 postive directions are rotated in driving, the Motor Vehicle middling speed is advanced, and be middle retaining this moment; Then promote Joystick 4 on the basis of middle retaining forward, forward gear 9 then moves backward, makes forward gear 9 and steamboat 8 engagements, drives steamboat 8 postive directions and rotates, and Motor Vehicle is advanced at utmost speed, and be high gear this moment.In the process of gearshift, if forward gear 9, backward gear 10 are in the gap between bull wheel 6, middle wheel 7, the steamboat 8 respectively, the shift fork 11 of Joystick 4 controls is just in time pushed clutch 5 aside, makes it be in separated state, conveniently puts into gear.
Claims (3)
1. motor vehicle gearbox, comprise input shaft (1), transmission shaft (2), output shaft (3), Joystick (4), be clutch (5) between described input shaft (1), the transmission shaft (2), described transmission shaft (2), output shaft are speed change gear between (3), it is characterized in that: described speed change gear is made up of (8) three wheels of bull wheel (6), middle wheel (7), steamboat of concentricity isoplanar, flexible connection each other; The gear teeth of bull wheel (6), middle wheel (7), (8) three wheels of steamboat are towards transmission shaft (2), are fixed with respectively tandem two gears towards speed change gear on the transmission shaft (2).
