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 means for automatically preventing a motor, which is hydraulically driven by a pump and mechanically drives an inertial load from a pumping action of the motor caused by being driven by said inertial load, comprising blocking a reverse power transmission. The blocking may be done by brake disc fixed to a transmission shaft or by declutching a pair of clutching members arranged across the shaft. The automatic actuation of the blocking action may be either mechanically or electrically effected.
