摘要： A transmission is disclosed for a wheeled vehicle. The transmission has a rotary input (14) to be driven by a rotary power source, e.g. an internal combustion engine. It has a rotary output (16) for driving a vehicle wheel. A transmission unit is coupled between the rotary input and the rotary output to transfer drive between them at a speed ratio which is continuously variable through a range which includes both negative ratios (providing a reversal of rotational direction between the rotary input and the rotary output), positive ratios (in which the rotary input and the rotary output rotate in the same direction), and a geared neutral ratio, in which the rotary output is stationary. In accordance with the invention, the transmission further comprises a brake (20) for braking the rotary output. The brake is provided with a control arrangement adapted to apply it when the speed ratio is set to the geared neutral ratio and to release the brake as the speed ratio is adjusted away from the geared neutral ratio.

摘要： If a hydraulic motor (23) (traveling wheel (27)) is rotated (or skidding) at high rate, and a hydraulic motor (24) is hardly rotated, a detection controller (68) compares the rotational speeds of both hydraulic motors (23, 24). Then the rotation detected by the rotation detectors (66, 67) to detect the traveling wheel (27) to be skidding, and moves a piston (71) to allow a negative brake (40) to give a braking force to the hydraulic motor (23), and rotate the hydraulic motor (24). In this way, this invention can release the traveling wheel from skidding without the use of a flow dividing valve.

摘要： A method of operating a brake system for a hydraulic motor, by feeding the hydraulic motor with at least one pump having a variable cubic capacity, in a closed circuit, providing a friction brake to brake the motor, providing a brake controller that controls an amount of applied frictional braking by the friction brake and an amount of applied hydraulic braking, and determining a level of actuation of the brake controller to detect normal and emergency braking situations. In normal braking situations, the proportional amount of frictional and hydraulic braking is managed as a function of parameters to cause progressive hydrostatic braking to occur by causing a ratio between the fluid flow rate delivered by the pump and the active cubic capacity of the motor to decrease progressively. In emergency braking situations there is a controlled sudden decrease in the ratio between the fluid flow rate delivered by the pump and the active cubic capacity of the motor, and then progressive hydrostatic braking occurs. The friction brake is activated during both normal and emergency braking situations.
