For overcoming the above-mentioned shortcoming of existing technology, the utility model provides that centre distance is 113 millimeters between a kind of input shaft and the II axle, and casing length is 343 millimeters, compact structure, volume compact type five retaining gearboxes little, applied widely.
The utility model solves the technological method that its technical problem adopted: a kind of compact type five retaining gearboxes, comprise casing, loam cake and top cover, and the length of said casing is 343 millimeters; In said top cover, shift control mechanism is installed, in said casing, variable transmission mechanism is installed, in casing, centre distance is 113 millimeters between said input shaft and the II axle through Bearing Installation for variable transmission mechanism input shaft, I axle and II axle.
Said input shaft is concentric with the I axle; The end that input shaft is installed in the casing has support holes; And link through this support holes and I axle head end, this I axle head end to tail end is set with four retaining gears, four or five retaining synchronizers, second gear, three retaining gears, two or three retaining synchronizers, first gear, a retaining reverse gear sliding gear collar and reverse gear successively; Between this I axle and each the retaining gear needle bearing is housed; Above-mentioned each synchronizer and one keeps off the sliding gear collar that reverses gear and links to each other with the loam cake declutch shift shaft through corresponding shift fork respectively, and wherein declutch shift shaft links to each other through the shift fork of chute with the operating mechanism that is installed in top cover; Said II axle head end to tail end is equipped with five retaining teeth, four retaining teeth, three retaining teeth, two retaining teeth, the retaining tooth and the tooth that reverses gear successively, on the corresponding position of tooth and casing of reversing gear, is set with the idle pulley that reverses gear through idler shaft.
Said synchronizer is a block type synchronization device.
Tooth on said each gear is thin and tall tooth.
Between said I axle and each the retaining gear needle bearing is housed.
On said input shaft and the I axle one to five the retaining gear respectively with the II axle on corresponding gear be meshed.
Reverse gear is meshed with the idle pulley that reverses gear on the idler shaft on the said I axle.
The idle pulley that reverses gear on the said idler shaft is meshed with the tooth that reverses gear on the II axle.
The beneficial effect of the utility model is: with the gearbox Design of length is 343 millimeters; Centre distance is 113 millimeters between input shaft and the II axle simultaneously, and each design of gears is thin and tall tooth, makes the volume of gearbox less; Compact structure has improved its installation capability in vehicle.The utlity model has the wide characteristics of vehicle scope of compact structure, suitable configuration.
