摘要： In a free-wheeling vehicle drive system in which the free-wheeling function is cut in and cut out entirely in response to normal driving operation of acceleration and deceleration, at least the signal corresponding to engine acceleration, which may be provided by the accelerator pedal, is subjected to delay before it may set a flipflop establishing the free-wheeling function. The braking signal, which may conveniently be derived from the brake-light switch, can likewise be advantageously delayed in its resetting of the flipflop in order that brief touching of the brakes should not disable free-wheeling. A more refined system which cuts in free-wheeling only after acceleration of the engine followed by the establishment of an idling condition of the engine can be used without the necessity of providing an overrunning clutch, since the control of a normal clutch connecting or separating engine and drive train can provide free-wheeling. The use of both slow-acting engagement of the clutch and an overriding fast-action engagement, and the taking account of engine speed, engine temperature, downward road slope and rapid changes of position of the accelerator pedal, can provide a sophisticated and nevertheless natural control of free-wheeling over a wide variety of driving conditions.
摘要翻译：在其中随着加速和减速的正常驾驶操作而切换和切断续流功能的再循环车辆驱动系统中，至少可以由加速踏板提供的与发动机加速度相对应的信号，在它可能设置触发器建立续流功能之前经受延迟。可以方便地从制动灯开关导出的制动信号同样可以有利地在翻转触发器时被延迟，以便制动器的短暂接触不应该禁止续流。可以使用更精细的系统，其仅在发动机加速后才能切换自由轮，然后建立发动机的空转状态，而不需要提供超速离合器，因为通常的离合器连接或分离发动机传动列车可以提供续航。使用离合器的慢动作接合和超控快速接合，以及考虑到发动机速度，发动机温度，向下的道路坡度和加速器踏板的位置的快速变化，可以提供复杂而自然的控制在各种驾驶条件下的续航。

摘要： A driven axle for a small vehicle such as a golf cart. The axle consists of two coaxially mounted shafts having a sleeve extending over both of the shafts. The sleeve is tightly held to one shaft and is held to the second shaft so that a predetermined level of applied torque will cause the second shaft to twist relative to the sleeve and the first shaft. Thus, the axle will drive coaxially mounted wheels at either end thereof and yet allow turning of the vehicle without substantial wheel slippage.
摘要翻译：用于小型车辆如高尔夫球车的从动轴。该轴由两个同轴安装的轴组成，其中两个轴上均有一个套筒。套筒紧紧地固定在一个轴上并被固定到第二轴上，使得预定水平的施加转矩将使第二轴相对于套筒和第一轴扭转。因此，轴将在其任一端驱动同轴安装的车轮，并且允许车辆转动而没有相当大的车轮打滑。

摘要： A garden type tractor of the hand manipulated and controlled type having two drive wheels thereon and a forwardly directed power take off onto which various attachments may be connected. The tractor includes a transmission of the planetary type enabling a change in drive speed and direction by the use of a manual shifting lever which may move into a position for locking the differential for the drive wheels. An attachment is provided for converting the tractor to a four wheel type and including an occupants seat for convenience and ease of control of the tractor. The drive train of the tractor includes an automatic clutch, chain drive, transmission and worm drive to the differential which provides a versatile drive arrangement.
