摘要： A walk behind self-propelled crawler snowplow includes a snowplow mechanism driven by an engine via a belt drive power transmission mechanism (109), and an overload protection device (130) associated with the belt drive power transmission mechanism for protecting the engine against overload. The overload protection device comprises a tension sensor for detecting the tension in an endless belt (103) and generating an electric overload signal to disengage an electromagnetic clutch (101) in the belt drive power transmission mechanism when a belt tension greater than a predetermined value is detected.

摘要： A continuously shifting-type steering system (Ts) includes a pair of left and right hydrostatic continuously variable transmissions (T 1 ,T 2 ) each of which is comprised of a hydraulic pump (18) and a hydraulic motor (19), and a pair of left and right planetary gear mechanisms (60 1 ,60 2 ) each having a first sun gear (61), a second sun gear (62), a two-step planetary gear (63) and a carrier (65). A first driving gear (45) connected to an engine (E), is operably connected commonly to the left and right first sun gears (61). Left and right second driving gears (46) secured to motor shafts (27) of the left and right hydraulic motors (19), are operably connected to the left and right carriers (65), respectively. Left and right output shafts (8 1 ,8 2 ) are operably connected to the left and right second sun gears (62), respectively. Thus, it is possible to provide an increase in the shifting range of the continuously shifting-type steering system (Ts), and an enhancement in low-output performance.

摘要： In a snow-removing machine, an expandable and contractible regulating mechanism (45) is coupled between a steering handlebar (6) of a machine body (3) including a snow-removing section and a drive section capable of being turned relative to the machine body about a wheel driving shaft, and is capable of regulating the level of the snow-removing section relative to the drive section. The expandable and contractible regulating mechanism (45) is comprised of a cylinder connected to the machine body, a piston (51) which divides the inside of the cylinder into a first chamber (49) and a second chamber (50), a piston rod (52) coupled to the piston and connected to the drive section, a communication passage (58,59) permitting communication between the first and second chambers, and an on-off valve (55) for opening and closing the communication passage. A high-pressure gas is filled in the first and second chambers, so that the expansion and compression of the high-pressure gas is permitted upon closing of the on-off valve. Thus, during a snow-removing operation of the snow-removing machine, vibration applied to the drive section can be absorbed utilizing the expandable and contractible regulating mechanism for regulating the level of the snow-removing section.
