摘要： A motorized vehicle has a vehicle body, at least a pair of wheels mounted on the vehicle body for undergoing rotation to cause the motorized vehicle to undergo travelling, and a pair of electric motors each mounted on the vehicle body to selectively undergo forward and reverse rotation to rotationally drive a respective one of the wheels. A first switch is connected to the electric motors so that operation of the first switch causes the electric motors to undergo rotation simultaneously in opposite directions to turn the motorized vehicle in a first direction while the motorized vehicle does not undergo travelling. A second switch is connected to the electric motors so that operation of the second switch causes the electric motors to undergo rotation simultaneously in opposite directions to turn the motorized vehicle in a second direction opposite to the first direction while the motorized vehicle does not undergo travelling.

摘要： A walk behind self-propelled crawler snowplow includes a snowplow mechanism disposed on a front portion of a vehicle body, an engine disposed on a longitudinal central portion of the vehicle body for driving the snowplow mechanism, a left crawler belt and a right crawler belt disposed on a left side and a right side, respectively, of the vehicle body, and left and right electric motors disposed on a rear portion of the vehicle body for driving the left and right crawler belts, respectively. With this arrangement, the crawler snowplow has a good weight balance such that the load or weight of the vehicle body is born evenly by the crawler belts. Since the snowplow mechanism and the crawler belts are driven separately by different power sources, the crawler snowplow can exhibit a good traveling performance regardless of the load exerted on the snowplow mechanism.

摘要： A self-propelled snowplow vehicle includes a vehicle frame equipped with an auger at a front end portion thereof and pivotally connected to a propelling frame equipped with driving wheels, and a frame lift mechanism for lifting the front end portion of the vehicle frame up and down relative to the propelling frame. The frame lift mechanism comprises an electro-hydraulic cylinder actuator having a piston rod and an electric motor rotatably driven to produce a fluid pressure for reciprocating the piston rod in response to operation of a manual operating switch. The snowplow vehicle also includes a control unit arranged to forcibly stop the electric motor when a predetermined time has elapsed after the operation switch is activated, the predetermined time being equal to an operating time of the cylinder actuator which is required to extend or contract the piston rod over a maximum stroke defined between a fully extended position and a fully contracted position of the piston rod.
