摘要： A motor vehicle structure includes two left and right bell-shaped suspension element supports arranged inside a front compartment close to a bulkhead of the vehicle. The suspension element supports are respectively adjacent to side walls of the front compartment. Each of the suspension element supports includes an internal face opposite the side wall. The structure also includes left and right spacers that extend respectively between the left and right suspension element supports and the rigid cross member, in a substantially longitudinal direction. The spacers are respectively anchored to the internal faces of the two suspension element supports. The spacers each have a skirt-shaped edge that can be applied to the suspension element supports, and a folded edge extending between a free end and an opposing attachment end to be joined to the cross member. The spacers include a central portion joining the folded edge and the skirt-shaped edge together.

摘要： A rotary engine comprises a rotor defining interiorly a plurality of radially disposed cylinders and a reciprocating, fluid-pressure-driven piston in said cylinder. Each piston carries a cross pin extending parallel to the axis of rotation and projecting through a radially elongated slot in the rotor. Rotation of the rotor about its axis is effected by the interaction of the cross pins with one or more fixed elliptical tracks disposed in planes normal to the axis of rotation.

摘要： An auxiliary hydraulic motor comprises a fixed casing having a cam, a cylinder block, an internal fluid distributor, and a through shaft which extends inside the casing along the axis of rotation of the cylinder block. The through shaft is constituted by a length of a vehicle transmission shaft. The motor includes an axially moving coupling member suitable, in a first position, for being engaged with the cylinder block and the shaft via first and second mechanical engagement means, and in a second position, for being disengaged from the cylinder block and/or the shaft.

摘要： A fluid operated stepping motor comprising a cylinder housing having one or more fluid cylinders to alternately displace at least two cam engaging members when pressure from a pressure source is applied to one of the cylinders. The cam engaging members are diametrically opposed. A cam is secured relative to the cylinder housing and having a plurality of teeth asymmetrically disposed thereon, is also provided. Each tooth has a power profile surface and an idle profile surface. The power profile surface is slidingly engageable by one of the cam engaging members when pressure is applied to displace the said one cam engaging member axially whereby the power profile surface will cause relative rotational displacement between the cylinder housing and the cam.

摘要： An hydraulic motor comprises two, three or more rows of pistons and cylinders which rows are selectively drivable by fluid under pressure supplied to the motor to provide for different motor speeds for a given delivery of working fluid to the motor. Nonoperative rows of pistons may be retracted to reduce friction losses between the piston''s followers and the cam track on which the followers react to rotate the motor rotor. A driving system employing the motor and a variable delivery fluid pump is also provided, the system thus having a plurality of speed ranges including high speed at low torque and low speed at high torque.

摘要： A rotary hydraulic engine is disclosed having a stationary crankshaft with an eccentric crank portion disposed thereon. A housing is rotatable about the crankshaft. At least two pairs of cylinders are connected to the housing and extend quadrilaterally therefrom. A piston is slidingly disposed within each cylinder, and is connected to an oppositely disposed piston so as to move in tandem when propelled by a fluid under pressure. An external valve mechanism is provided which is connected to the cylinders so as to sequentially actuate the pistons contained therein when supplied with fluid under pressure. A scotch yoke assembly integrates the motion of the pairs of pistons into a balanced array of weight and force vectors rotating around the axis of the eccentric crank portion of the stationary crankshaft. This sequential reciprocation of the pairs of pistons imparts a rotary motion to the housing, the rotary motion in turn causing the housing to act as a flywheel. A transmission mechanism such as a belt drive is attached to the housing for conveying rotary motion to a desired mechanical apparatus, or alternatively for driving the engine. As a result, the engine may be driven by an external source of energy such as wind for compressing air, and later selectively driven by the compressed air collected.

摘要： A hydraulic-powered motor for stepwise operation has a plurality of radial pistons in a rotatable cylinder block, the pistons engaging a cam track having a number of indentations which is different from the number of the pistons. Electrically operated valves are provided and are energizable in sequence to apply pressure pulses to the pistons to cause stepwise rotation of the cylinder block. Detent means may be provided to prevent rotation of the cylinder block in the absence of a pressure pulse to any one of the pistons.
