20080290618 | Vehicle - When a vehicle turns, a body and a left and a right wheel are inclined inward of a turning circle. Consequently forces are exerted to an operator in an up-down direction, which leads to reducing discomfort felt by the operator. In addition, since a gravity center of the vehicle is moved inward of the turning circle, a turning stability of the vehicle is improved. | 11-27-2008 |
20080315537 | Apparatus for Transporting Products in Crates or Containers - Apparatus for transporting products including a body having ground wheels ( | 12-25-2008 |
20090033045 | PAYLOAD MODULE FOR MOBILITY ASSIST - A ground vehicle and a method for articulating a payload module for mobility assist are disclosed. The ground vehicle comprises a chassis; and a payload module capable of articulating relative to the chassis to assist the mobility of the ground vehicle. The method comprises articulating a payload module relative to a chassis. | 02-05-2009 |
20100295259 | Adjustable Suspension Leveling Apparatus - A suspension height modification apparatus includes a first portion that is securable to a vehicular biasing suspension device and a second portion that is securable to a vehicular frame. The apparatus includes an axis along which a suspension height may be determined between the vehicular frame and the vehicular wheel assembly. The apparatus includes a movable portion which may be actuated along such axis to adjust suspension height, and a spacer device connectable between an upper ball joint stud and a steering knuckle. | 11-25-2010 |
20110148052 | MECHANICAL DEVICE FOR TILT CONTROL - The invention relates to a device that comprises:

20120175851 | Safety System for Equipment Controller - A heavy equipment system is provided that includes a tractor for hauling a trailer, wherein the trailer may have its height adjusted by a hydraulic system controlled by a bank of control levers. Also included is a safety system that comprises a blocking member, such as a handle, a sensor and a communication system. The safety system operates to sense and communicate to a driver of the tractor the possibility that the trailer is in the raised position by sensing when the blocking member is in a position to allow access to the control levers. Advantageously, such a system can guard against a driver driving into a low overpass or other hazard with the trailer in an elevated position. | 07-12-2012 |
20130200579 | Accessory Cart - In the specification and drawings an accessory cart is described and shown with a base, a housing element that is connected to the base and extends upward from the base, and a platform, which is connected to the housing element with the height of the platform being automatically adjustable. | 08-08-2013 |
20140210170 | AIR SPRING FOR VEHICLES - An air spring for a vehicle with a lifting function includes an upper rolling piston and a lower rolling piston disposed opposite to each other. A rolling bellows encloses a compressed air space and has double rolling folds. The pressure effective surfaces of the rolling folds are coordinated with each other in such a manner that, during dynamic spring operation of the air spring over a predetermined spring travel, the pressure effective surface of the rolling fold on the lower rolling piston is larger than the pressure effective surface of the rolling fold on the upper rolling piston. | 07-31-2014 |
20140306409 | SUSPENSION LEVELING SYSTEM - A vehicle suspension assembly including a first end, a second end, and a hydraulic actuator. The hydraulic actuator is movable between a retracted position providing the vehicle suspension assembly with a first overall length, and an extended position providing the vehicle suspension assembly with a second overall length greater than the first overall length. The vehicle suspension assembly is configured to raise a vehicle when moved from the first overall length to the second overall length by the hydraulic actuator. The vehicle suspension assembly is configured to lower the vehicle when moved from the second overall length to the first overall length by the hydraulic actuator. | 10-16-2014 |
20160001622 | VARIABLE HEIGHT VEHICLE - A system and method for raising and lowering a vehicle. The system includes a four-bar linkage provided for each wheel. The four-bar linkage includes a first three linkage assembly and a second three linkages assembly. The first three linkage assembly maintains the orientation of the vehicle relative to the wheel during the lifting and lowering while the second linkage assembly provides the power to lift and lower the vehicle. Power provided by a hydraulic cylinder is pivotably coupled to the second linkage assembly. A steering assembly is provided between the four-bar linkage assembly and the wheel. The four-bar linkage vehicle lifting assembly may be provided on agricultural vehicles, construction vehicles, or any desired vehicle. | 01-07-2016 |
20220135124 | VEHICLE WITH TILT FRAME AND SPRING DAMPER SYSTEM - A vehicle with a base frame to which at least two sprung suspensions, in particular sprung wheel suspensions, for driven, non-driven, steerable or non-steerable contact elements, for example wheels, are attached which can be steered by means of a steering knuckle and are located on both sides of the longitudinal direction of travel, in each case transversely to the direction of travel, a tilt frame, tiltable in a tilt axis with respect to the base frame. A steering tube is rotatably attached to the tilt frame in the steering axis and automatically tilts with the tilt frame, at least one track rod connected to the track rod actuating element, and a linear or rotary track rod actuating element rotatable over a guide element. The track rod actuating element is displaced by tilting the tilt frame about the tilt axis and independently thereof by rotating the steering tube about the steering axis in such a way that the steerable contact element is given a steering movement by the track rod actuating element by means of the at least one track rod and no substantial change in the camber of the contact elements takes place during cornering, wherein the vehicle comprises at least one spring damper system which is suitable and provided for reducing a pendulum tilt of a tilt frame about the vertical zero position. | 05-05-2022 |
