| 123 | Running wheel | US818292 | 1997-03-14 | US5758976A | 1998-06-02 | Heinz Lause; Vincent Dreyer |
| A running wheel is slidably supported on a stationary axle between the axle and the bearing bore with a large bearing play and a small Hertzian stress. The axle has a circumferential section which is defined by its sector with a sector angle of less than 180.degree., wherein its radius of curvature is substantially equal to the radius of curvature of the inner wall of the bearing bore. In accordance with the desired bearing play, the radius of curvature of the remaining circumferential section of the axle is smaller than the radius of curvature of the bearing bore. The direction of the main stress acting upon the running wheel lies in the section of the central plane of the axle sector with the larger radius. | ||||||

| A vehicle attachment has a pivoting frame connected to the rear driven axle of a vehicle, drivable wheels mounted on opposite ends of a drivable axle, an adjustable tension element that is capable of providing varying degrees of downward force on the drivable wheels. A sprocket is connected to the vehicle rear axle and another sprocket is connected to the drivable axle, the two sprockets being interconnected by a chain such that rotation of the vehicle rear axle causes rotation of equal velocity of the drivable axle. | ||||||
| 127 | Vehicle wheel lock | US675961 | 1984-11-28 | US4628714A | 1986-12-16 | Elmer L. Batteas; Donald W. Hamlett |
| Disclosed is a vehicle wheel lock which includes a spindle having an axial passage therein. A hub is rotatably mounted on the spindle and has formed therein an internal socket. A locking member is nonrotatably but axially moveably mounted on the spindle. The locking member is configured to nonrotatably engage the socket of the hub and is moveable from an unlocked position out of engagement with the socket to a locked position in engagement with the socket. A spring is provided for urging the locking member toward the locked position. A lock assembly is provided for moving the locking member toward the unlocked position. The lock assembly includes a key operable lock which includes a lock body and a rotating member that is key operable to rotate with respect to the lock body. A first screw threaded member is connected to the rotating member of the lock and a second screw threaded member is threadedly engaged with the first screw threaded member. The second screw threaded member is nonrotatable with respect to the spindle and is arranged to transmit force to the locking member. | ||||||
| 128 | Wheel hub clutch assembly | US524667 | 1983-08-19 | US4538714A | 1985-09-03 | Tooru Kagata; Motoi Fujikawa |
| A wheel hub clutch assembly comprises a cylindrical body formed therein with a first set of clutch teeth and fastened to a wheel hub, a sleeve member fixed to the outer end of a drive axle and located within the body, a clutch member formed with a second set of clutch teeth and axially slidably mounted on the sleeve member for rotation therewith, a cam ring operatively coupled with the outer end of a stationary axle tube for the drive axle and rotatable on the sleeve member, a cam follower ring axially slidably mounted on the sleeve member for rotation therewith and cooperable with the cam ring to be displaced toward the clutch member in response to rotation of the drive axle, and a connecting member engaged with the cam follower ring and the clutch member to permit relatively inward movement between the cam follower ring and clutch member. The improvement comprises a first spring arranged between the cam follower ring and the clutch member for loading the cam follower ring toward the cam ring and cooperable with the connecting member for loading the clutch member for movement away from engagement with the first clutch teeth, and a second spring arranged in parallel with the first spring between the cam follower ring and the clutch member for loading the clutch member for movement toward engagement with the first clutch teeth. | ||||||
| 129 | Suspension assembly for a wheel and brake | US543571 | 1983-10-19 | US4500111A | 1985-02-19 | Ji Y. Woo |
| A suspension assembly couples a wheel assembly (16) and a brake assembly (60) to a frame (10). The suspension assembly includes a support (20) for receiving an axle (24). The axle carries the wheel assembly (16) at one end of the support (20) and forms a drum (46) at the other end of the support (20) for engagement with the brake assembly (60). Therefore, the support (20) separates the wheel assembly (16) from the brake assembly (60) so that the brake assembly (60) brakes the wheel assembly (16) via the axle (24). | ||||||
| 130 | One-piece locking clutch | US209647 | 1980-11-24 | US4365696A | 1982-12-28 | Thomas M. Telford |
| An improvement to a clutch housing, including a clutch mechanism manually operable to lock and unlock the vehicle axle to the vehicle wheel hub, is disclosed. The improvement comprises the clutch housing attachable to the vehicle wheel hub by a lock ring disposed around the clutch housing. The lock ring engages an annular groove within the vehicle wheel hub allowing the clutch housing to be secured to the wheel hub. | ||||||
| 131 | Undercarriage for adverse terrain vehicle | US12292 | 1979-02-15 | US4210219A | 1980-07-01 | Norman D. Oswald; Harry S. Mankey |
| A detachable undercarriage for use on adverse terrain vehicles comprises an elongate hollow load-bearing frame having three or four axles rotatably supported thereon. Sprockets are mounted on at least two of the axles, and chains are constrained around the sprockets to drivingly interconnect the axles. The center axle in the three axle embodiment and the center two axles in the four axle embodiment are positioned below a plane extending through the axes of rotation of the outermost two axles to facilitate skid steering of vehicles incorporating the undercarriage. Alternatively, all the axles can be aligned with larger wheels mounted on the center axle in the three axle embodiment or the center two axles in the four axle embodiment to facilitate skid steering. In certain applications of the nonaligned axle embodiments structure is provided for selectively aligning all the axles to increase vehicle stability. Also included in the undercarriage is a drive assembly having a motor connected to a transmission mounted inboard or outboard of the frame. In one configuration, an endmost axle is chain driven from the transmission, with the middle axle being chain driven from the endmost axle. In an alternate configuration, an endmost axle and the middle axle are directly chain driven from the transmission. | ||||||
| 132 | Wheel assembly with slip clutch | US624864 | 1975-10-23 | US4018298A | 1977-04-19 | Ray D. Frazee |
| Wheel and axle assembly for a small vehicle such as a riding lawnmower which includes a frame and an engine mounted upon the frame, the assembly comprising an axle having opposite first and second ends journalled mounted upon the frame for rotation and drivingly connected to the output of the engine conventionally through a transmission. First and second wheels are provided for mounting, respectively, on the first and second axle ends. The first wheel is rigidly connected to the first axle end for rotation with the axle such as by pinning or by a key. A torque-limited driving connection is provided between the second wheel and the second axle end, the torque-limited driving connection permitting relative rotation between the second wheel and axle when a predetermined torque level is exceeded. This torque-limited device may include a frictional drive connection between the second wheel and the axle. The second wheel may include a rim housing journalled mounted on the second axle end for rotation relative to the axle, and a friction clutch for drivingly connecting the rim housing to the axle. The clutch may include a clutch plate mounted on the second axle end for rotation with the axle and friction pads for engaging the plate, the pads being carried by the rim housing. | ||||||
