| 141 | Dual wheel puller/dolly | US620345 | 1990-11-29 | US5112070A | 1992-05-12 | Kevin C. Hahn |
| A dual wheel puller/dolly is provided and consists of a pair of mobile elongated frame members with an elongated rod extending transversely therebetween and a jack mechanism cooperative with the rod. An elongated roller is rotatively mounted onto the top of each frame member to engage with a pair of large heavy motor vehicle wheels. When the jack mechanism is operated the large heavy wheels will be lifted upwardly to be moved about. One of the elongated frame members can also be used with other components, such as a pair of chains and a socket, as a wheel hub puller so as to facilitate the removal of a wheel bearing therefrom. | ||||||

| 144 | Tire dismantling and setting apparatus | US362264 | 1989-06-06 | US4930966A | 1990-06-05 | Kuo-Feng Chien |
| A tire dismantling and setting device includes a roller holder for loading or holding tires thereon, an axle retainer pre-fixed on a car axle, a driving bolt rotatably secured on the roller holder, and a pair of tire fasteners fastening the tires on the roller holder, whereby upon a clockwise rotation of the driving bolt to urge the bolt coupled with the axle retainer against the car axle, the holder and the fastened tires can be dismantled conveniently and safely. When rotating the driving bolt counter-clockwise, the bracket, the tire fastener and the fastened tires are pushed rearwardly to be mounted on a car axle conveniently. | ||||||
| 145 | Truck tire mounting device | US195656 | 1988-08-17 | US4872694A | 1989-10-10 | William B. Griesinger |
| A wheel mounting device of fork-like design, adapted to lift and position a wheel by means of two horizontal parallel rollers, two vertical parallel rollers, a main-frame plate with caster assemblies mounted thereunder, and extensions forming a triangle, with a foot plate being mounted at the apex of the triangle, and said foot plate being on the same horizontal plane as the main-frame plate and the horizontal rollers. | ||||||
| 146 | Arrangement for influencing the keeping of a driving direction by a motor vehicle | US887263 | 1986-07-21 | US4678197A | 1987-07-07 | Willy Stein |
| An arrangement for influencing the keeping of a driving direction by a motor vehicle, which has at least one non-driven wheel support body which is mounted on a wheel suspension for rotation about an axis, in such a manner as to be able to conduct driver education and/or motor vehicle testing while operating in a border region between stable and unstable driving behavior at relatively low speeds comprises a holding component which is rigidly connected to the wheel support body, and a caster wheel which is mounted on the holding component for rotation about its rotational axis and also for turning about an additional axis which is substantially normal to the axis of the wheel support body and to the rotational axis of the wheel. A connecting device prevents the rotation of the wheel support body about its axis and is connected to a non-rotatable part of the wheel suspension. In this manner, lateral guiding forces normally holding the non-driven regular wheels of the motor vehicle are eliminated or at least significantly reduced, in that the caster wheel turns about the additional axis in an almost instantaneous response to lateral disturbance forces acting on the vehicle and readjusts its position accordingly to simulate vehicle behavior during skidding even at low driving speeds. | ||||||
| 147 | Vehicle wheel-removing and handling device | US575959 | 1975-05-09 | US4042139A | 1977-08-16 | Harold R. Pernsteiner; Ernest H. Streckert |
| A wheel-removing and handling dolly device for dual or single-tired vehicle wheel assemblies consisting of a wheeled base having an upstanding post containing a hydraulic lifting ram cylinder whose piston rod is connected to a carriage assembly slidably engaged on the post. Respective gripping lever arms are provided on opposite sides of the carriage assembly, the lever arms having tire-gripping members horizontally pivoted to their outer end portions adapted to grippingly engaged diametrically opposite portions of a wheel assembly. The inner end of one of the lever arms is operatively connected to a hydraulic clamping cylinder assembly. A hydraulic wheel puller cylinder is carried horizontally by the carriage, extending between the gripping lever arms and having an extensible piston rod provided with a wheel hub-engaging head portion. A manually operated ram pump is carried on the carriage assembly and is connected through respective control valves to the lifting cylinder, the clamping cylinder and the wheel puller cylinder. After a wheel assembly is clamped and pulled from a vehicle, the wheel assembly can be rotated to a horizontal position, providing access to its brake drum or other parts for repair, cleaning or other servicing operations. | ||||||
| 148 | Auto wheels placer | US370823 | 1973-06-18 | US3976212A | 1976-08-24 | Ramon Sanchez |
| The present invention refers to a device to place automobile wheels in their respective axles, as well as truck wheels and other vehicles wheels, after the car has been raised with a regular jack. | ||||||
| 149 | Truck wheel dolly | US34691673 | 1973-04-02 | US3836027A | 1974-09-17 | GARDNER C |
| A truck wheel dolly easily implaced and adjustable for use in lifting, transporting and remounting heavy truck wheels and tires, and this with a mimimum of effort or difficulty as such wheels are lifted, removed and replaced relative to the wheel axle. The dolly includes its own self-contained hydraulic jack with lever and like coupling means for lifting an elevatable frame supported by links to a base frame. The elevatable frame includes hinged support bars or means supplying versatility in use of the equipment. Wheel support bar means as well as auxiliary spacer bars are provided. Wheels and casters are supplied so as to provide fine adjustment in placement of the dolly preparatory to use. Support rail means is provided the lift frame so that a wheel may rest thereagainst and be supported thereby so that oil seals and the like at journaling areas will not be deleteriously disturbed.

| 150 | Vehicle wheel handling apparatus | US34169773 | 1973-03-15 | US3830387A | 1974-08-20 | VIRNIG S |
| A vehicle wheel handling apparatus for holding and manipulating heavy vehicle wheels of single or tandem nature, comprises a frame including an upright post with a slidably mounted carriage thereon having wheel engaging means such as a pair of arms swingably mounted relative to one another, each arm having a pivotally mounted wheel engaging member adjacent the end thereof. Means are provided for tightening the wheel engaging means on single or tandem vehicle wheels to retain the wheels. A wheel removing mechanism is provided to urge hard to remove wheels from the vehicle. The apparatus permits single or tandem vehicle wheels to be lifted from the vehicle axle, moved about, retained during servicing, or pivoted about a horizontal axis by an operator.

| 153 | Vehicle wheel dolly | US3653527D | 1970-11-03 | US3653527A | 1972-04-04 | SEYMOUR GLENN C |
| A device for removing, transporting, and replacing heavy truck wheels with tires mounted thereon. A dolly is provided with a linkage system for first gripping the wheel between the wheel rim and tire periphery at the upper side of the wheel, and thereafter lifting the wheel by force applied to the gripped portion of the wheel to release it from the axle. A single power source, preferably a hydraulic ram, applies to the linkage an upward thrust to first grip and then to raise the wheel. In a modified arrangement the linkage and power source are supported on a motor vehicle to facilitate transportation of the removed wheel.
