摘要： A skid steer vehicle has sprung suspensions, variable displacement pumps and motors connected to those pumps that drive the wheels on the vehicle as well as an electronic controller that receives signals that indicate fore-and-aft acceleration of the skid steer vehicle. Based on these signals, the controller determines whether the forward acceleration exceeds a predetermined value and locks up the rear suspensions if that value is exceeded. It also determines whether the forward deceleration exceeds a predetermined value and locks up the front suspensions if that value is exceeded. The signals can be provided by an accelerometer, a satellite receiver, wheel/motor speed sensors, sensors in the pumps that signal the specific displacement of the pumps such as their swash plate positions, or memory locations that contain previously calculated specific displacement commands that are used to drive the pumps to a particular specific displacement.

摘要： A skid steer vehicle has a chassis with four drive wheels suspended from the chassis that are damped by four damping cylinders. An electronic controller varies the damping of the cylinders in an automatic mode, based on certain operational parameters of the vehicle, and in a manual mode in response to operator selection of a desired degree of suspension damping.

摘要： A skid steer vehicle has sprung suspensions that can be locked to prevent vertical movement with respect to the chassis of the vehicle. The operator controls include a switch that the operator can manipulate to lock the suspensions on command. The switch is mounted on a joystick that is used to perform other vehicle functions such as moving the vehicle, raising loader arms, or tilting the bucket or other implement attached to the loader arms. The switch is located on the joystick such that the operator can manipulate the switch without having to remove his hands from the joystick.

摘要： A skid steer vehicle has a sprung suspension system including four wheels mounted on four swing arms that are pivotally coupled to the chassis of the vehicle. An electronic controller is connected both to position sensors coupled to the swing arms to sense the position of the swing arms and wheels with respect to the chassis and also to hydraulic cylinders that control the position of the swing arms and wheels. The electronic controller determines the average position of each suspension and controls the flow of fluid to the cylinders to keep the swing arms and wheels at their proper target height when vehicle load changes.

摘要： A skid steer vehicle with sprung suspensions is configured to lock the suspensions whenever the operator manipulates a manual control that generates a signal to move the loader arms or the bucket of the vehicle. The operator control, such as a joystick, sends a signal to an electronic controller indicating that the operator has moved the control and is thereby requesting the loader arms or bucket to move. The electronic controller responds to this signal by moving the loader arms or bucket and simultaneously locking the suspensions.

摘要： A control system for a skid steer vehicle reads a load height sensor, a load amount sensor, and a vehicle speed sensor to derate the otherwise commanded acceleration, deceleration and turning rate on the vehicle when the vehicle has too great a load, too high a load, or the vehicle is going too fast.

摘要： A skid steer loader has a chassis with spring-loaded suspensions that are pivotally coupled to the chassis closer to the center of gravity than the wheels. The suspensions include fore-and-aft extending swing arms that pivot about a lateral axis with respect to the chassis. A torsion spring such as a torsion bar is coupled to the control arm to provide torsional support for the suspension. The torsion spring is anchored to the chassis nearer the center of gravity than the point where the swing arm is coupled to the chassis.

摘要： A skid steer vehicle is supported on four gearboxes that function both as control arms and as speed reduction gearboxes. Each side of the vehicle's chassis has two gearboxes to which it is coupled. A hydraulic motor is fixed to each side of the chassis to drive the gearboxes on that side. The motors are arranged such that their drive shafts extend longitudinally along the chassis, with a front shaft engaging the front gearbox and a rear shaft engaging the rear gearbox. The gearboxes include three speed-reducing right angle gear sets coupling an axle extending from the gearbox to the motor driving that gearbox.
