Abstract
The utility model discloses a drive axle for a wheat harvesting machine, and belongs to the field of motor vehicle speed changers. The drive axle structurally comprises a box body and an upper cover installed on the top of the box body. A first shaft, a second shaft, a third shaft and a half shaft are installed in the box body. An input belt pulley is installed at one end, outside the box body, of the first shaft, an HST connection sleeve and an HST connection plate are installed at the other end, outside the box body, of the first shaft and on the end portion of the second shaft on the same side respectively, and the HST connection plate is provided with an HST hydrostatic transmission device in a connecting mode. The second shaft is provided with a third-gear driving gear. The third shaft is provided with a brake, a third-gear driven gear, a second-third-gear hub gear sleeve, a second-gear driven gear, a first-gear driven gear and a first-gear gear hub gear sleeve from left to right. According to the drive axle, engagement sleeves are adopted in each gear of main speed change for gear shifting, so that the early failure of the gears is avoided, automatic adaptation of the HST hydrostatic transmission device replaces the operating control function of a clutch, and backward driving is achieved through the reversing function of the HST hydrostatic transmission device.
Description
Technical field
The utility model relates to vehicle transmission field, specifically harvesting wheat machinery ransaxle.
Background technique
The power input mechanism of the ransaxle that all kinds of middle-size and small-size harvest machineries of coupling are used mostly at present is clutch, and in ransaxle inside, be provided with a plurality of forward gears of different speed ratios and reverse gear, this complex structure, frequent operation, causes driving safety to reduce.Only have driver to use fixing operating method, could skillfully carry out, this improves driving training cost greatly.In addition, frequent operation causes driver's attention to be easily dispersed, and can affect driving safety.
summary of the invention
Technical assignment of the present utility model is for above deficiency, and a kind of rational in infrastructure, fitting operation harvesting wheat machinery ransaxle is easily provided.
The utility model solves the technological scheme that its technical problem adopts: the upper cover that this harvesting wheat machinery comprises casing and is arranged on casing top with ransaxle, one axle, two axles, three axles and semiaxis are installed in casing, described axle one end outside casing is provided with input belt pulley, the end of two axles of the other end of one axle outside casing and homonymy is provided with HST connecting sleeve and HST land, is connected and installed with the quiet liquid driver of HST on HST land; On two axles, be provided with three gear driving gears, on three axles, be disposed with from left to right break, three gear driven gears, two or three gear tooth hub tooth covers, two gear driven gears, a gear driven gear and a gear tooth hub tooth cover.
Described semiaxis comprises left half axle and right axle shaft, between left half axle and right axle shaft, differential assembly is installed, and the outer end of left half axle and right axle shaft is provided with limit reduction gear.
The top of described upper cover is provided with gearshift top cover, is provided with shift rod in upper cover, and selector fork is installed on shift rod.
With ransaxle compared to the prior art, each gear of main transformer speed has adopted engaging sleeve gearshift to harvesting wheat machinery of the present utility model, and the soldered tooth number of teeth of simultaneously bearing gearshift impulsive load is many, and the gear teeth do not participate in gearshift, thereby has avoided the too early damage of gear; HST land is installed on the casing side between an axle, two axles, for the quiet liquid driver of HST is installed.The commutation function that function and the quiet liquid driver of HST are controlled in the operation that utilizes the automatic adaptability of the quiet liquid driver of HST to replace clutch realizes reverse travel.Therefore have reasonable in design, be easy to processing, safe and reliable, long service life, the feature such as easy to operate.
