摘要
A hydraulic system for limited wheel slip of a traction drive system includes first and second pilot directional valves between a hydraulic pump and first and second hydraulic wheel motors. If a wheel slips, the first or second pilot directional valves moves to a first position directing some hydraulic fluid through a restricted passage to the slipping motor and the remainder through an unrestricted passage to the opposite motor. Absent wheel slip, the pilot directional valve is in a second position directing all of the hydraulic fluid through an unrestricted passage to the corresponding motor. The first and second pilot directional valves detect wheel slippage and move between the first and second positions based on a first pilot signal corresponding to the pressure sensed entering the respective pilot directional valve, which is balanced against a biased spring and a second pilot signal from the opposite motor.
