摘要:
A heat transfer device (1) comprising a body bounding a cavity for receiving a heat transfer medium; an inlet and an outlet for providing a fluid connection to said cavity. Interconnecting means (10) are provided at each of the inlet and outlet for providing a fluid connection to said inlet and outlet, at least one of the interconnecting means (10) being configured to interconnect with and provide relative movement between and a substantially consistent fluid connection with an interconnection means (10) of an adjacent device such as a similar heat transfer device over a range of spacing between bodies of said devices.
摘要:
A motion simulator (10) has a body tub (12) fixed on a carrier platform (14), the carrier platform being supported via motion control apparatus (52, 54, 56, 58), each having bearings which translate along an inclined path, the motion control apparatuses together providing six degrees of motion for the carrier platform.
摘要:
A vehicle suspension system has a gas-sprung hydraulic strut (6,7) for each of its four wheels (2,3). Each liquid actuator chamber (8) of the struts (6) at one end of the vehicle is connected (9) to a further chamber (10) in the diagonally opposite strut (7), which further chamber (10) acts in the opposite direction to the actuator chamber (13) of that strut (7). A linear potentiometer (26) within each strut (6,7) provides a signal representative of the strut length to an on-board computer (28), which, when it detects a difference in the signal from any strut sensor (26) from a predetermined value, causes a proportional servo-valve (35) to admit hydraulic liquid from the actuator chamber of that strut at a flow rate proportional to the detected difference to return the strut length towards its predetermined value.
摘要:
A vehicle having an electrical drive wheel hub system (30) and the hub system incorporated in the vehicle has a wheel hub (18) driven by an electric motor (31) formed by a brushless DC motor having stators (40) and rotors (42). The electric motor is arranged to drive an epicyclic gear system (32) which provides a reduction gear arrangement to drive the hub (18). Located entirely within the periphery of the stator is power circuitry and control circuitry for the electric motor, the circuitry being provided on toroidal printed circuit boards (70, 71).

摘要:
A motor land vehicle (10) includes a fire-guarded battery pack chamber (12) containing a battery system (22), the chamber having a relief port (34) with a bust disk (36), the chamber having a fire guard including a sheet of material comprising a first protective material which is ceramic and a second protective layer which is a carbon material.
