A hydraulic cylinder retarder includes a hydraulic cylinder mechanism, a hydraulic oil conveying mechanism and a hydraulic oil valve mechanism. A piston component of the hydraulic cylinder mechanism is connected to a transmission device. Resistance to the piston movement of the hydraulic cylinder mechanism is generated by the hydraulic oil conveying mechanism and the hydraulic oil valve mechanism, so as to reduce the operation speed of the transmission device.

A traction control system is provided for a vehicle having wheels driven on a primary axle via an engine, and wheels on a secondary axle torsionally isolated from the engine. Wheel speed sensors and brakes are provided for each wheel. A motor/hydraulic pump is operatively associated with each secondary axle wheel for selectively powering the secondary axle wheel or being regenerativly powered by the secondary axle wheel for regenerative braking. A clutch is provided to connect each secondary axle wheel with the secondary axle wheel's motor/hydraulic pump. An accumulator is provided to hydraulically power the secondary axle wheels and to accept regenerative pressure from the secondary axle wheel's motor/hydraulic pump. A wheel valve is provided for each respective secondary axle wheel for selectively connecting the secondary axle wheel's motor/hydraulic pump with the accumulator. A controller is provided to control the primary axle and secondary axle wheels. The controller commands braking and powering of the primary and secondary axle wheels during low traction events.
