This application describes systems and techniques for adjusting one or more setting(s) of a vehicle based on detected condition(s) to avoid damage due to contact of the tires with a body, chassis, or other components of the vehicle. In some instances, the vehicle may determine a ride height of the vehicle, determine a limited range of steering angles based at least in part on the ride height, and control operation of the steering system of the vehicle based at least in part on the limited range of steering angles. In some instances, the vehicle may determine a steering angle of the vehicle, determine a limited range of ride heights based at least in part on the steering angle, and control operation of the suspension system of the vehicle based at least in part on the limited range of ride heights.

The present invention relates to a variable load hydraulic control device comprising an inner tube able to be coupled to an upper tubular head to form an internal chamber and an external chamber, in addition to an inner casing, a floating piston, able to slide between the inner tube and the inner casing, a retaining ring, an upper spring, located between the floating piston and an extension of a washer located inside the upper tubular head, a lower spring, located between the floating piston and an extension of the inner casing, a control surface, a leak opening to communicate the external chamber and the internal chamber, wherein the static load of the hydraulic control device determines the position of the floating piston and the section of passage through the leak opening.

A damper assembly includes an outer cylinder, an inner cylinder positioned at least partially within the outer cylinder, a plunger positioned at least partially within the inner cylinder and coupled to a rod, an aperture extending through the rod, an annular piston coupled to the inner cylinder, and a valve assembly. The rod is positioned at least partially within the inner cylinder and has an outer dimension that is smaller than an inner dimension of the inner cylinder. The plunger and an interior of the inner cylinder at least partially define a first chamber. The valve assembly is in fluid communication with the first chamber and a second chamber. The annular piston extends between the inner cylinder and the outer cylinder, and the annular piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define the second chamber.

An insulator for a vehicle suspension and a method of manufacturing the same, may include an insulator having a housing which is configured to be engaged with a vehicle body and in which a hook protrusion is formed to protrude from an upper end opening of the housing; a bush which is configured to be engaged with a piston rod of a shock absorber, wherein a vibration-proof rubber, a core, and an outer pipe are integrally mounted in the bush, and wherein the bush is press-inserted into and fixed in an inner space of the housing so that the bush becomes hooked upward to the hook protrusion; and a fixing plate press-inserted into and fixed in the inner space of the housing so that the fixing plate is in contact with a lower end portion of the bush and supports the bush from a lower side thereof.

A three-point link having two control amis forming an acute angle and meet at a central joint. The central joint has a cylindrical dome extending perpendicular to a plane defined by the control amis. The central joint has a joint ball penetrated by the dome. To prevent separation of the central joint, it has a captive securing device which functions as a stop that extends perpendicular to an axial direction. The securing device is penetrated by the dome and is secured against axial withdrawal by an annular securing clement. Viewed in axial direction, the annular securing element is arranged on a side of the captive securing device) remote of the joint ball and engages in a circumferential groove of the dome. The annular securing element is snugly surrounded in radial direction by the captive securing device to prevent a withdrawal of the annular securing element from the circumferential groove.

A suspension travel control system (1046) for a vehicle suspension is disclosed. The suspension travel control system includes a stop post (834) secured to the vehicle frame and a suspension travel control formation that includes a base (1042) and a body (1048). The stop post (834) is positioned in a space defined by the body (1048). The suspension travel control formation may be secured to the axle, the main support member or incorporated into the axle coupling assembly to provide a rebound and jounce stop as well as longitudinal redundancy in the event of the failure or loss of a longitudinal linkage.

Disclosed herein is a hydraulic jounce bouncer comprising a damper body, a shaft telescopically engaged with the damper body, a piston slidably disposed within the damper body and threadedly coupled to a first end of the shaft, wherein the piston has at least one compression port therethrough, and a negative spring disposed between the shaft and the damper body.

Methods are provided for proactively controlling a component of a system. The system may comprise a vehicle and the component may comprise a suspension of the vehicle. According to various aspects, methods may include obtaining information regarding a travel surface along a travel path that the system will travel at a future time and, based on the information regarding the travel surface, controlling the component of the system to traverse the travel surface. Controlling the component based on the information regarding the travel surface may comprise comparing the information regarding the travel surface to information regarding at least one physical constraint of the system and/or comparing frequency content of the information regarding the travel surface to a threshold frequency. Proactive control methods may provide improved response to disturbances and improved tracking and isolation because a suspension may be controlled with reduced or substantially zero delay.

A vehicle suspension system for a vehicle having a body supported on a frame includes a first suspension component having a surface and a bracket cantilevered from the surface, a second suspension component including a surface portion, and a spring element mounted to one of the bracket and the surface portion of the second suspension component. Interaction between the spring element and the another of the bracket and the surface portion of the second suspension component limits upward travel of the body of the vehicle.

The present invention relates to a novel robot drive train that is robust, and low cost. The drive train is capable of ascending obstacles greater than the height of its wheels, protects the robot against shocks/vibration, and is highly maneuverable, such as able to execute a zero-point turn. To control the bogie in a variety of scenarios, a novel mechanism is used to selectively limit the articulation range of the bogie and/or programmatically apply a preload to the bogie axle.
