摘要： A pump housing assembly includes a housing, a hub portion, and a flange. The housing has an end cowling defining a transition from a central portion of the housing to a transverse end portion. The hub portion extends longitudinally outwardly from the transverse end portion of housing. The flange extends radially outwardly from the outward end of the hub and is in spaced longitudinal relation to the end of the cowling to create a space to receive a head of a mounting bolt. The flange has an outer periphery with a pair of tangentially extending slots having an open end. The space for receiving a head of a mounting bolt is less than the length of a shank of a mounting bolt, to minimize the length of the housing. The slots have a width sufficient to receive the movement of a shank into and out of the open ends of the slots.

摘要： An electronic transmission control system is provided that can achieve a transmission ratio based on the operator inputs and the current vehicle operating conditions. The transmission constantly connects the engine to the load, and the transmission ratio is only varied by a change in command from the present invention. The transmission's mechanical function is solely to vary the ratio between its input and output. In using the present invention, an operator must select an operating mode, either automatic or manual, using a two-position switch. While in the automatic mode, the present invention determines the vehicle speed by considering the position of the throttle and the operator's use of brakes. In the manual mode, the present invention further considers the operator's selection of a gear condition.

摘要： A method to provide a smooth shift during mode changes of an HMT when using mechanical clutches by reducing the power into the transmission momentarily when a shift is initiated by cutting fuel to the engine, and also reducing power in the hydrostatic transmission by crossporting the fluid circuit, and then reapplying power to both the engine and the transmission after the clutch has been shifted.

摘要： A swing speed compensation device is provided for use with a flow sharing hydraulic system. The present invention is mounted within the metering spool of a flow sharing valve and includes a poppet that is attached to a spring retainer. The spring retainer encases a compression spring which pushes against a plug and has a drain hole that, depending upon the position of the spring retainer and poppet combination, can vent excess pressure within the present invention to a hydraulic pump tank. When a flow sharing hydraulic system starts or stops, there is a rush in the fluid flow that can cause a spike in the system pressure. The present invention absorbs this pressure spike, allowing for the fluid flow to gradually increase or decrease as the system starts or stops.

摘要： A hydraulic motor (2) with a braking device (8), is acted upon by means of a control fluid via a brake release line (6). The brake release line (6) is used to allow a continuous flushing flow of control fluid through the hydraulic motor at the same time as the release of the brake. The braking device (8) is connected to the casing of the hydraulic motor (2). An outlet opening (12) of the hydraulic motor (2) leads via a leakage-oil line (13) to the tank for the control fluid. In a hydraulic travel drive with a closed hydraulic circuit, the brake release line (6) can be connected to the shut-off device (4) for the servo adjustment system of the variable-displacement pump (1), and the leakage-oil line (13) of the hydraulic motor (2) can lead to the tank for the entire hydraulic fluid in the system. Since the control fluid coming from the tank for the hydraulic fluid is always cooler than the hydraulic fluid used to drive the hydraulic motor (2) and circulating in the closed circuit, a cooling effect on the hydraulic motor (2) is obtained.
摘要翻译：具有制动装置（8）的液压马达（2）经由制动器释放管线（6）通过控制流体作用。制动器释放管线（6）用于允许控制流体在与制动器的释放同时通过液压马达的连续冲洗流动。制动装置（8）连接到液压马达（2）的壳体。液压马达（2）的出口（12）经由泄油线（13）引导到用于控制流体的罐。在具有闭合液压回路的液压传动驱动器中，制动器释放管线（6）可连接到用于可变排量泵（1）的伺服调节系统的切断装置（4），并且泄漏油液压马达（2）的管路（13）可以导致系统中整个液压流体的油箱。由于来自液压油箱的控制流体总是比用于驱动液压马达（2）的液压流体冷却并在闭路中循环，所以获得对液压马达（2）的冷却效果。
