摘要： A wheel end assembly for a steerable rear axle of a four wheel steer motor vehicle chassis comprises a constant velocity joint drivingly interconnected with an axle shaft of the steerable rear axle, along a lateral axis defined by the axle shaft, and a wheel assembly for transmitting driving torque therebetween. A yoke has a main body portion with a central, laterally-extending pass-through for the constant velocity joint and is fixedly mounted to the chassis. The yoke has an upper and a lower ball joint arm which laterally extend towards the wheel assembly, where each ball joint arm has a ball joint passage therethrough. A knuckle for transferring steering rotation to the wheel assembly comprises a flat plate body with a central, lateral opening for the constant velocity joint to pass through and splined upper and lower ball joint pockets. The knuckle is configured to fit within lateral volume defined by the yoke main body and ball joint arms to minimize lateral packaging space needed for the wheel end assembly. Ball joints allow the knuckle to swivel relative to the yoke. An adapter has a central passage for the constant velocity joint to pass through and is fixed to the knuckle flat plate body and the wheel assembly to transmit rotation therebetween.

摘要： A steering system for a vehicle is provided that includes a steering knuckle which is rotatable about an axis. The steering knuckle includes an upper attachment point and a lower attachment point. The attachment points define the steer axis. A rotational drive unit is connected to the steering knuckle for rotating the steering knuckle about the steer axis. A control module receives a steering input corresponding to the desired Ackerman angle and commands the rotational drive unit to rotate the steering knuckle about the axis to the desired Ackerman angle. Rotational drive units for each side of the vehicle ensure that the wheels are turned to the appropriate Ackerman angle for each wheel. The rotational drive unit may include an electric motor, or a pneumatic or hydraulic pump. In one preferred embodiment, the rotational drive unit includes a fluid housing and the shaft connected to the steering knuckle. The shaft includes a vane extending therefrom and into the housing. The fluid pump pumps fluid into the housing to rotate the vane with the shaft and steering knuckle about the axis in response to a command from the control module.

摘要： An adjustable tie rod assembly having a rod member and a knuckle assembly. The knuckle assembly includes a housing and an annular connector. The housing has a stem member and a bore with a longitudinal axis that is skewed to a longitudinal axis of the stem member. The annular connector is disposed in the bore in the housing. The annular connector pivotably couples the first end of the rod member to the housing. The first stem member has an engagement portion that is adapted to be secured to a relay rod.
