Abstract
The utility model relates to an energy-saving gearbox of a mini-four-wheel tractor. A fixed driving gear which is arranged on a I shaft is changed into a duplex sliding gear, wherein, the I shaft gear is still used for being engaged with a range-shift high-speed gear on a II shaft; an added high-speed gear of a I shaft is used for being engaged with a range-shift low-speed gear on the II shaft; the range-shift low-speed gear on the II shaft is changed into a triple gear. The tooth number of the high-speed gear of the I shaft can be designed optionally as required to obtain reasonable variable-speed ratio, consequently improving intensity and service life; the utility model saves oil consumption at the time of empty load.
Description
Technical field
The utility model relates to a kind of tractor with small four wheels Energy-saving gearbox.
Technical background
Existing tractor with small four wheels has six forward gears and one to reverse gear as shown in Figure 1.The gearbox of this tractor is to export design according to the power of tractor full load, and tractor gear ratio when zero load does not change yet, the engine speed height, and oil consumption is big.Another patent " tractor with small four wheels Energy-saving gearbox " (application number: 02270750.6) make the gear on the I axle into double crosslinking sliding gear of my application, engagement by fork controls I shaftgear can reach the purpose of regulating gear ratio, thereby make tractor when zero load, can obtain higher speed, save oil consumption.But owing to be subjected to the restriction of the driving gear on I axle and II axle distance between shafts and the II axle, the I shaftgear on the I axle and the II axle on the gear ratio of secondary speed change top gear can only be 20: 35.The gear ratio of the high low speed of tractor can not arbitrarily be set as required.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, can not be subjected to the restriction of distance between shafts, arbitrarily the tractor with small four wheels gearbox of tractor high and low speed speed ratio is set.
For achieving the above object, the utility model adopts following technological scheme:
A kind of tractor with small four wheels Energy-saving gearbox described in the utility model comprises housing, be installed in live axle I axle in the housing and be installed in actuation gear, transmission shaft II axle, III axle, the IV axle on the I axle and be installed in driving gear on the transmission shaft, the actuation gear that is installed on the I axle is a double crosslinking sliding gear, and this double crosslinking sliding gear comprises I shaftgear and the I axle high gear that is fixed together; Secondary speed change low speed gear on transmission shaft II axle is a triple gear, and this gear comprises the energy-conservation driven gear in the middle of being positioned at and lays respectively at the reverse gear of both sides, secondary speed change low speed gear.
The best gear ratio of I axle high gear and energy-conservation driven gear is 24: 31.
After adopting technique scheme, have double crosslinking sliding gear I shaftgear and I axle high gear on the live axle I axle, regulate the energy-conservation driven gear engagement on I axle high gear and the II axle or separate just to obtain two kinds of different gear ratio by shift fork, can in the tractor zero load, save oil consumption.Secondary speed change low speed gear adopts triple gear, takes out the engagement of a gear and I axle high gear separately, can not be subjected to the restriction of I axle and II axle distance between shafts, determines a gear ratio the most rational.Be more suitable for the transformation of existing tractor with small four wheels, make it all to be much improved in intensity and working life, the unloaded time is economized oil consumption.
Description of drawings
Fig. 1 is the structural representation of existing tractor with small four wheels gearbox;
Fig. 2 is an an embodiment's of the present utility model structural representation.
Embodiment
As shown in Figure 2, a kind of tractor with small four wheels Energy-saving gearbox described in the utility model comprises housing 1, be installed in live axle I axle 2 in the housing 1 and be installed in actuation gear, transmission shaft II axle 3, III axle 4, the IV axle 5 on the I axle 2 and be installed in driving gear on the transmission shaft, the utility model is that the stationary drive gear that will be installed on the I axle 2 changes double crosslinking sliding gear into, wherein I shaftgear 8 still be used for II axle 3 on secondary speed change high gear 9 engagement, the I axle high gear 7 of increase be used for II axle 3 on 11 engagements of energy-conservation driven gear.Make the secondary speed change low speed gear on the II axle 3 into triple gear, the energy-conservation driven gear 11 in the middle of being positioned at is used for and 7 engagements of I axle high gear, plays the effect of energy-conservation gear; The gear of the left and right sides plays reverse gear and secondary speed change low speed gear respectively.11 of energy-conservation driven gears and 7 engagements of I axle high gear can not be subjected to the restriction of I axle and II axle distance between shafts.I axle high gear 7 is 24: 31 with the best gear ratio of energy-conservation driven gear 11.Gear ratio is more reasonable.Help transformation to existing tractor with small four wheels.
