Golf cart with hydraulic braking

A driveline for recreational vehicle, the driveline comprising:

• a prime mover;
• a plurality of tractive assemblies including tractive elements;
• an axle coupled with the tractive elements;
• a gearbox configured to exchange torque between the prime mover and the axle;
• a hydraulic pump coupled with the prime mover, the hydraulic pump and the prime mover configured to be back-driven by the tractive elements through the axle and the gearbox;
• and
• a pressure valve operable to adjust hydraulic back-pressure experienced by the hydraulic pump to provide braking for the tractive elements through the prime mover, the gearbox, and the axle.

A recreational vehicle, comprising:

• a frame;
• and
• a driveline coupled with the frame, the driveline including:
• a prime mover;
• a plurality of tractive assemblies including tractive elements;
• an axle coupled with the tractive elements;
• a gearbox configured to exchange torque between the prime mover and the axle;
• a hydraulic pump coupled with the prime mover, the hydraulic pump and the prime mover configured to be back-driven by the tractive elements through the axle and the gearbox;
• an electronic pressure control valve operable to adjust hydraulic back-pressure experienced by the hydraulic pump to provide braking for the tractive elements through the prime mover, the gearbox, and the axle;
• a fluid reservoir either (i) defined by a housing of the gearbox, or (ii) defined by a tank separate from the gearbox, the fluid reservoir configured to receive hydraulic fluid pressurized by the hydraulic pump;
• a line switching valve configured to be transitioned between a first position and a second position responsive to a change in a direction of travel of the recreational vehicle, wherein, in the first position, the line switching valve directs fluid from a sump of the fluid reservoir to a first side of the hydraulic pump and, in the second position, the line switching valve directs fluid from the sump of the fluid reservoir to a second side of the hydraulic pump to account for a change in direction of the hydraulic pump due to the change in direction of travel of the recreational vehicle;
• and
• a pressure regulator fluidly coupled with an output of the hydraulic pump, the pressure regulator configured to set a maximum pressure allowed to be output by the hydraulic pump.
