Description

Изобретение относитс к коммуналь4- ному машиностроению, в частности к подметально-уборочным машинам.FIELD OF THE INVENTION The invention relates to utility engineering, in particular to sweepers.

Известен гидроходоуменыпитель, со держащий установленный в корпусе ве- дущий вал, св занный с гидромотором и несущий одну шестерню посто нного зацеплени , зацепленную с шестерней выходного вала, установленной на нем; и выполненной в полумуфтой, при этом на выходном валу, св занном по концам с карданными валами привода, размещет на муфта дл св зи с ним шестерни. A hydraulic flow meter is known, which contains a drive shaft mounted in the housing, connected to the hydraulic motor and carrying one permanent gearing gear that is engaged with the output shaft gear mounted on it; and made in the half coupling, at the same time, on the output shaft, connected at the ends with the drive cardan shafts, will place gears on the coupling for coupling with it.

Недостатком известного гидроходо- уменьшител вл етс увеличение осевых габаритов и мала долговечность при (частом) посто нном использовании .A disadvantage of the known hydro-shrinking device is an increase in axial dimensions and low durability with (frequent) continuous use.

Целью изобретени вл етс уменьшение осевых габаритов и увеличение долговечности.The aim of the invention is to reduce the axial dimensions and increase durability.

Муфта может быть выполнена двух- позиционной, а ведущий вал - разрезным .The coupling can be made two-position, and the drive shaft - split.

Паз, по крайней мере один, венца полумуфты разрезного вала может быть выполнен с шириной, больше ширины - других пазов этих венцов, дл взаимодействи с соответствующими зубь ми муфты в положении сбалансированности карданных валов.A groove, at least one, of the rim of the half-coupling of the split shaft can be made with a width greater than the width of the other grooves of these rims, for interacting with the respective coupling teeth in the balanced position of the drive shafts.

На фиг.1 изображен гидроХодоумень- шитель, продольный разрез; на фиг.2 - разрез А-А на фиг.1.Figure 1 shows a hydro-HF unit, longitudinal section; figure 2 - section aa in figure 1.

Гидроходоуменьшитель может быть выполнен в двух вариантах: дл установки на транспортное средство, имеющее на заднем мосту дополнительную полумуфту, св занную с дифференциалом , а также дл установки между приводом (двигателем) и задним мостом . The hydraulic low reducer can be made in two versions: for installation on a vehicle that has an additional coupling half on the rear axle connected with the differential, and also for installation between the drive (engine) and the rear axle.

В первом варианте гидроходоумень- шитель содержит установленный в корпусе 1 ведущий вал 2, св занный с Ј гидромртором 3 и несущий по меньшей мере одну шестерню 4 посто нного зацеплени , зацепленную с шестерней 5 выходного вала 6, установленной на нем свободно (на подшипниках) и выполненной с полумуфтой 7. На валу 6 установлена муфта 8 с вилкой 9. Муфта 7 выполнена с внутренними венцами 10. При выполнении вала 6 разрезнымIn the first variant, the hydraulic regulator contains a drive shaft 2 installed in the housing 1 and connected to the hydraulic distributor 3 and carrying at least one gear 4 of permanent engagement engaged with the gear 5 of the output shaft 6 mounted on it freely (on bearings) and made with coupling half 7. On the shaft 6 there is a coupling 8 with a plug 9. The coupling 7 is made with inner rims 10. When the shaft 6 is made split
