Abstract: A drive mechanism (10) for rotating a pair of tandem wheel assemblies (24, 26) journalled on a centrally pivoted tandem drive housing (16). A jointless elastomeric belt (82) extends about the wheel assemblies which are driven by two chains (32, 38) entrained over respective sprockets (34, 36, 40, 42) contained within the tandem drive housing. A planetary gear set (109) is effective to powerably drive both chains with a differential action to minimize the influence of the belt loading upon the chains. The planetary gear set and the sprockets are constructed to deliver a greater torque to the rear wheel assembly (24) than the front wheel assembly (26) through the chains.

Abstract: A compact nutating traction drive transmission (10) having particular utility in a vehicle (232) as a steering differential. The transmission (10) includes an input body (38) rotatable about a central axis (32), first and second cone-like members (84, 86) rotatably mounted on the body (38) on an inclined axis (32), and a pair of traction rings (60, 62) reacting against the respective cone-like members (84, 86). A first embodiment includes a tubular shaft (110) and a solid main shaft (108) which are rotatably mounted and pilotably interconnected along the inclined axis (88), and a coupling apparatus (114) is utilized for transmitting torque independently from the cone-like members (84, 86) to their respective shafts (110, 108). Similar axially compact gear trains (206) are driven by the respective shafts (110, 108) which have a construction and gear train ratio sufficient for maximizing the effectiveness of the transmission (10). A second embodiment includes a tubular shaft (110), a solid shaft (108), and an extension shaft (282) connected to the second cone-like member (86') for providing a greater resistance to bending centrally thereof than the first embodiment.

Abstract: In the use of fuel injection pumps, a distributing rotor is often utilized to sequentially deliver fuel from an inlet to a combustion chamber on an engine in combination with one or more reciprocating high pressure pistons. Due to the positioning of the various passages through which the fuel is directed, cavitation of the pump is often experienced which has a very serious effect on the life of the components within the pump. The fluid distribution apparatus (10) of the present invention provides a single delivery passage (58, 60) between the pumping chambers (22, 24) of the reciprocating pistons (26, 28) and the distributing rotor (82). With this arrangement, fluid that is communicated from the bore (54) to the pumping chambers (22, 24) in response to the intake stroke of the pistons (26, 28) is directed back through the same passage (58, 60) during the pressurization stroke of the pistons (26, 28). The positioning of the single delivery passages (58, 60) prevents the fuel injection pump from experiencing the severe cavitation that is common with previous designs and thus the fore-shortened life of the pump components.

Abstract: Previously disclosed distributor fuel injection pumps for internal combustion engines offer the advantages of reduced size, weight, and cost of a fuel injection system. However, these pumps have not been able to provide relatively high fuel injection pressures which could improve fuel combustion for better fuel economy and lower noxious emissions. In contrast, the subject distributor fuel injection pump (14) generates relatively high fuel injection pressures in a relatively compact arrangement. A semi-spherical nutator member (74) freely rotatably mounted on an oblique journal (66) of a drive shaft (38) imparts high speed harmonic motion to at least one reciprocating pump plunger (310, 314) for pressurizing the fuel. A relatively large semi-spherical bearing interface (82, 86) between the nutator member and a pump housing (34) accomodates very high pumping reaction loads. A distributor rotor (348) for sequentially delivering the pressurized fuel to more than one engine combustion cylinder is rotatively driven by a planetary gear reduction mechanism (392, 396, 424, 428, 432, 436, 440, 444, 448) coupled to the drive shaft. Very little force is required to adjust either the timing or quantity of fuel injection which are adjustable by angular movement of at either a normally stationary planetary ring gear (396) or a fuel metering collar (146), respectively.

Abstract: A load responsive fluid power and control system in which the speed of the prime mover (15), driving a fixed displacement pump (11), is varied to maintain a constant pressure differential between pump discharge pressure and maximum system load pressure, above a certain predetermined system flow level and in which this constant pressure differential is maintained by pump flow bypass control (36, 10), at system flows below this predetermined level.

Abstract: An earthmoving bucket (10) for use with various types of wheel and track-type earthworking and construction machines is constructed to provide great strength and rigidity while at the same time not being unduly bulky or heavy. The bucket (10) is further characterized by simplified manufacturability and cost advantages. Previous earthmoving buckets, which required considerable strength and durability, were quite heavy and bulky, with respect to bucket size, and required complicated, costly, and time-consuming assembly procedures. The earthmoving bucket (10) of the present invention utilizes a pair of unitary cast lift brackets (52, 54) which incorporates the pin bores (56) for the lift linkage, the rack-back stops (58), and the bucket dump stops (60).

Abstract: The present cooling system (21) provides a limited flow rate to clutches (26, 28) (for example in industrial vehicles) during disengagement and provides additional cooling flow to the clutches (26, 28) during partial engagement and controls the pressure level of the fluid from the source of cooling fluid (42) by operation of a valve mechanism (46) which is responsive to a control mechanism (110). Upon full engagement, the valve mechanism (46) automatically reduces the volume of cooling fluid to the clutches (26, 28) and simultaneously reduces the pressure level of the cooling flow from the source of cooling fluid (42). This cooling system provides the needed volume of cooling fluid during partial engagement of the clutches (26, 28) and also reduces the volume of cooling fluid during disengagement to reduce drag forces while further reducing the volume of cooling fluid during full engagement to conserve horsepower.

Abstract: A method and apparatus is provided for manufacturing a reinforced elastomeric hose. Other reinforced hoses are prepared in individual stations for particular parts of the reinforced hose consequently requiring large amounts of manufacturing floor space. Still other hoses that are made while utilizing small amounts of floor space do not provide a high strength braided reinforcement member. A reinforced hose (10) is produced by continuously braiding a tubular reinforcement member (16) on a mandrel (50), progressively removing the reinforcement member from the mandrel (50), and at approximately the same axial location extruding a liner (26) and cover (28) onto the reinforcement member (16) adjacent the mandrel (50). After leaving the extruders (33, 34), the formed hose (10) is pulled at a linear rate faster than the hose (10) is being produced in order to change the braid angle of the braided reinforcement member (16) to a predetermined smaller braid angle. As the hose (10) leaves the extruders (33, 34), it is pulled through a curing mechanism (30) to cure the hose (10) while the braid angle is at the predetermined angle. Upon release and cooling of the hose, the hose rebounds to an optimum braid angle of approximately 54o 44'. Th braided reinforcement member (16) provides the high strength characteristics while the extruding of the liner (26) and cover (28) at approximately the same axial location near the braiding mandrel (50) minimizes the manufacturing floor spaced and reduce cost.

Abstract: System for monitoring an engine operating parameter, such as oil pressure, which varies in proportion to engine speed, monitors the parameter relative to an upper and lower setpoint. Oil pressure is sensed by a transducer (122) and the sensed pressure is monitored by a pair of comparators (252, 266) which compare the sensed oil pressure with reference voltages corresponding to the upper and lower setpoints. The reference voltages may be selectively altered by a switch (124) in order to change the pressure setpoints. The outputs of the comparators (252, 266) control an annunciator (16) which indicates when the monitored pressure is below either of the setpoints. A circuit (75) is provided to inhibit operation of the annunciator (16) by the comparators (252) monitoring pressure relative to the uper setpoint when the engine's speed is below a predetermined value. The output of the comparator (266) monitoring pressure relative to the lower setpoint controls a service-hour meter (18) to provide an indication of the total elapsed time that the engine is running.
