Claims

[Scope of Claim for Utility Model Registration] (1) In a configuration in which an HST type transmission device 1 in which a hydraulic pump P and a hydraulic motor M are arranged in parallel is attached to a transmission case 4 to drive axles 18L and 18R, the hydraulic motor A transmission case equipped with an HST type transmission, characterized in that a PTO shaft 7 for extracting the rotation of a hydraulic pump P to the outside is brought close to a pump shaft 2 of a hydraulic pump P and protrudes in the opposite direction. (2) The transmission case 4 of claim (1) has a wide and large diameter lower part that accommodates side clutches and side brakes on the left and right axles 18L and 18R,
It has a thin and vertically long upper part that accommodates the transmission part from the hydraulic motor M to the side clutch and the transmission part to the PTO shaft, and the HST type transmission 1 is mounted on one side of the upper part. A transmission case equipped with an HST type transmission, characterized in that a power take-off pulley 7a of a PTO shaft 7 is arranged on the other side. (3) The transmission part of claim (2) is arranged such that the input shaft 6 to which the hydraulic motor M is connected is sandwiched between the thin upper part of the transmission case 4, the PTO shaft 7 is placed in the upper part, and the deceleration part is placed in the lower part. The shaft 10 is horizontally mounted, and the small reduction gear 12 of the reduction shaft 10 is meshed with the driving gear 6a of the input shaft 6 and the large reduction gear of the reduction shaft 10, and the small reduction gear 12 of the reduction shaft 10 is meshed with the large diameter gear 13 for input of the side clutch. H.S.
A transmission case equipped with an HST type transmission, which is characterized by being placed closer to T type transmission 1. (4) With respect to the axles 18L and 18R supported substantially at the center of the transmission case 4 in side view according to claim (2), clutch arms 22L and 22R of side clutches are mounted on one side in the longitudinal direction, and HST is mounted on the other side. A transmission case equipped with an HST type transmission, characterized in that it constitutes a mounting part of a type transmission 1.
