20110280719 | Fan And Shroud Assembly - An axial flow fan assembly includes a plurality of fan blades surrounded by a shroud. The shroud includes an annular first wall which extends radially outwardly, an annular second wall which extends axially and radially outwardly, and an annular third wall which joins the first wall to the second wall. The third wall has a curved cross sectional shape, and has a minimum diameter part which is positioned approximately half-way between the upstream and downstream edges of the fan blades. There is a desired relationship between the radius of curvature of the third wall and the diameter of the fan. There is a desired relationship between the height of the first wall and the diameter of the fan. The fan blades have an upstream edge which is upstream with respect to the first wall. The third wall has a minimum diameter part which is positioned approximately half-way between the upstream and downstream ends of the fan. | 11-17-2011 |
20120055719 | FRONT DRIVE ASSEMBLY - A vehicle front drive assembly includes a housing supporting a plurality of belt driven pulleys, including an input pulley driven by an engine of the vehicle, a first driveshaft, a front PTO drive, and a second driveshaft. The first driveshaft can be connected directly between the engine and the input pulley. The front PTO drive has a housing rotatably supporting an input member, an auxiliary drive member and a PTO driveshaft, and enclosing a PTO transmission. A second driveshaft can be coupled between the engine and the auxiliary drive member. The first driveshaft is removable from the assembly when the second driveshaft and the front PTO drive are connected between the engine and the input pulley. The second driveshaft and the front PTO drive are removable from the assembly when the first driveshaft is connected between the engine and the input pulley. | 03-08-2012 |
20120058850 | Auxiliary Drive Assembly For A Front Drive Assembly - A vehicle front drive assembly includes an auxiliary drive assembly for a vehicle which is driven by an engine which is cooled by a fan. The auxiliary drive assembly includes an input pulley for receiving torque from the engine, a fan drive pulley, a belt engaging the input pulley and the drive pulley and an auxiliary drive housing. The housing supports the belt and has a first opening adapted to receive a torque transmitting member which transmits torque from the engine to the input pulley. The housing has a second opening which receives a fan drive shaft which transmits torque from the fan drive pulley to the fan. | 03-08-2012 |
20120080908 | FENDER MOUNTING ASSEMBLY - A fender mounting assembly is provided for a vehicle steerable wheel. The fender mounting assembly includes a base mounted on the axle and a support pivotally coupled to the base about a pivot axis which is aligned with the kingpin axis. A bumper arm projects from the support. A stop support with a curved arm is fixable at different positions on the axle, and a stop member is fixable at different positions on the arm. The stop member is engagable with the bumper arm to limit pivoting of the fender. The base has a cylindrical pivot pin which is aligned with the kingpin axis. The support has a bearing housing which receives an annular bearing, and the annular bearing receives the pivot pin. A torsion spring is coupled between the base and the support. The fender mounting assembly allows the fender to rotate relative to the wheel. The fender pivot axis is coincident with the kingpin axis and includes stops which can be set in a range of positions to prevent unwanted fender rotation. | 04-05-2012 |
20120261202 | TRACTOR HOOD AIRFLOW SYSTEM - A vehicle engine enclosure includes a tractor frame which supports an engine. A cooling system is mounted on the frame. The cooling system has a housing which surrounds cooling components. A hood is mounted on the frame and encloses the engine and the cooling system. The hood includes a top panel and left and right hood side panels. The top panel has outlet vents formed therein. A pair of left and right side plates are mounted on the frame. A rear end plate covers a rear end of the hood. A plurality of seals are placed between these components so that a duct is formed which collects hot air and moves it vertically through the vents to prevent re-ingesting of the hot air. | 10-18-2012 |
20120308373 | AXIAL FAN ASSEMBLY - A fan assembly includes an axial flow fan between an inlet stator and an outlet stator. The inlet stator has inlet stator blades which extend outwardly from an inner ring. Each inlet stator blade has a downstream edge which has a tangent which is oriented at a first variable angle with respect to a plane which is perpendicular to the fan axis. The first angle increases with increasing distance from the inner support ring. The outlet stator has a plurality of outlet stator blades which extend outwardly from a second inner ring. Each outlet stator blade has an upstream edge which has a tangent which is oriented at a second variable angle with respect to a plane which is perpendicular to the fan axis. The second angle decreases with increasing distance from the inner ring. | 12-06-2012 |
