摘要： An anti-creep device for use with an air spring of a tractor-trailer is shown. The anti-creep device includes a support member which is mounted inside the air spring for movement between a blocking position and an articulating position. In the articulating position, the full range of compression between the top plate and piston of the air spring can be exercised. In the blocking position, the support member limits the downward movement of the top plate relative to the piston. Therefore, the support member limits downward movement of the frame rail of the trailer with respect to the axle and trailing arm. The support member can comprise a pivotable plate, a bladder filled with an incompressible fluid, a vertically telescoping arm or upper and lower bumpers rotatable into and out of vertical alignment.

摘要： A tractor having a steerable axle that pivotally moves laterally in response to a corresponding steering action of the steerable wheels mounted on the steerable axle and is also pivotally supported for oscillatory pitching movement about a longitudinal axis is disclosed wherein an oscillation stop is provided in the form of an arcuate track mounted to the steerable axle and a pair of transversely spaced rollers engageable with the arcuate track through the entire range of lateral movement of the axle to limit the amount of permissible oscillatory pitching movement. The arcuate track has a center of curvature that coincides with the vertical pivot axis for the lateral movement of the axle. The rollers are spaced on opposing sides of the longitudinal axis and have rotational axes that are generally aligned with the center of curvature of the arcuate track. The upper surface of the arcuate track has an undulating configuration to vary the permissible vertical pitching motion of the axle as the steering angle of the steering mechanism changes.

摘要： A structure for a housing for an axle assembly and method for manufacturing same is disclosed. The housing includes a tube which is formed by casting. The tube is cast having a brake flange, a spring seat, a shock absorber pad, and an outer end for mounting wheel bearings, all of which are integrally formed therewith. The tube is generally hollow and cylindrical in shape, but is formed having an outer circumferential surface which is generally circular in shape and an inner circumferential surface which is generally oval in shape. Thus, the wall thickness of the tube is not uniform about the circumference thereof. Rather, the wall thicknesses of the upper and lower portions of the tube are somewhat greater than the wall thicknesses of the side portions thereof. The wall thicknesses of the upper and lower portions of the tube are sized to accommodate vertically oriented loads induced therein which are generally larger than horizontally oriented loads which are normally encountered in use. The tube is cast from an iron alloy and is subjected to an austempering heat treatment process.

摘要： In the forward undercarriage of a self-propelled hillside combine, all components for support and control of the transverse equalizing or balance beam, are below the floor level of a forward portion of the combine's separator body. In a compact structure which maintains good access to the separator concave and stone trap, and also to the hydraulic cylinders used to control the balance beam, the leveling cylinders diverge widely from a center pivot assembly so as to provide smooth action in control of the balance beam and also to minimize bending moments in the balance beam.

摘要： Apparatus for stabilizing a material handling vehicle during implement manipulation is provided. Dual hydraulic cylinders are provided on each side of the vehicle intermediate the vehicle's frame and a spring-biased solid axle. A lockout valve having a pneumatically actuated check valve in fluid communication with one-way check valves and flow restriction valves corresponding to each of the upper and lower ports of the respective hydraulic cylinders is mounted on the vehicle's frame and is in fluid communication with a reservoir of hydraulic fluid. When the vehicle is not caused to travel, the pneumatically actuated check valve is closed allowing no hydraulic fluid flow between the ports of the hydraulic cylinders and thereby locking the then-present fluid in each of the chambers of the hydraulic cylinders which prevents the movement of the pistons thereof and, hence, any displacement of the front axle relative to the vehicle frame. When the joystick controlling travel is actuated, a hydraulic signal is generated which is translated into a pneumatic signal effective to open the check valve. The system provided greatly increases vehicle stability during implement manipulation thereby increasing vehicle capacity without necessitating the use of means such as outriggers.

摘要： In a wheeled vehicle such as an excavator, a pivotable axle for two of the wheels can be locked against pivoting by means of two blocking cylinders each of which is controlled by its own valve. Each valve is closed by venting a control conduit and applying a valve member against a seating, the valve member being subjected to the action of a return spring.

摘要： A heavy duty spring suspension for an off-road vehicle including an axle assembly formed of a transversely extending axle housing and a forwardly extending tongue rigid with the axle housing, the forward end of the tongue having a front ball and socket connection with the chassis. Vertically arranged adjacent the axle housing, and in centered position, is a damped spring suspension device which is connected at its upper end to the chassis and at its lower end to the axle assembly. In the preferred embodiment the suspension device is of "T" shape with the arms of the "T" including a transversely extending hinge type connection with the chassis. The lower end of the suspension is connected to the axle housing by a rear ball and socket connection, the front and rear ball and socket connections, together, defining a fore-and-aft extending roll axis. In an alternate embodiment the suspension device is of inverted "T" shape having a transversely extending hinge type connection with the axle housing, the hinge type connection in both cases providing rigidity so that relative rolling movement is confined to the ball and socket connections thereby to keep the suspension device in generally upright position. An auxiliary suspension device is provided having a damped biasing spring of the centering type connected from the chassis to the axle assembly at a point eccentric to the roll axis for relatively biasing the axle assembly toward a centered position parallel to the chassis.

摘要： A stabilizer for improving the lateral stability of an articulated wheel loader of the type having a rigid front axle and an oscillating rear axle or frame. The stabilizer comprises rubber-like resilient members mounted between the rear axle and frame having an exponentially increasing restraining force versus compressive deflection characteristic to prevent free and unrestrained oscillation of the axle in relation to the frame at excessive angles of axle oscillation, thereby increasing the lateral tipping angle of the loader.
