A system according to this invention for transmitting power hydraulically to and from the wheels of a motor vehicle includes an accumulator containing fluid at relatively high pressure, a reservoir containing fluid at lower pressure, and a pump/motor driveably connected to the wheels and having an inlet, an outlet, and a variable volumetric displacement for pumping fluid between the accumulator and the reservoir. A first circuit connects the inlet to the reservoir and the outlet to the accumulator. A second circuit, which connects the inlet to the accumulator and the outlet to the reservoir, includes a first path having a low flow rate capacity, a second path having a higher flow rate capacity. A controller switches between pumping operation and motoring operation, opens and closes the first path during motoring operation, and reduces the displacement before switching between pumping operation and motoring operation. The first path includes a first valve responsive to the controller for opening and closing a connection between the accumulator and the inlet, and a first orifice arranged in series with the first valve having a relatively low flow rate capacity. The second path, arranged in parallel with the first path between the accumulator and the inlet, includes a second valve responsive to the controller for opening and closing a connection between the accumulator and the inlet, and a second orifice arranged in series with the second valve having a higher flow rate capacity than that of the first orifice.

A projection system for forming an image, comprising a light source generating light beam; a color wheel used for performing color separation on the light beam of the light source, comprising a motor having a shaft, a carrier pivoted to the shaft of the motor, and a plurality of color filters fixedly disposed at the periphery of the carrier to form at least one gap; and a digital micromirror element used for reflecting the performed filtered light beams of the light source from the color wheel to form the image.

A rotary compressor having an improved supporting structure and a smaller size thereof, reducing the vibration and noise and providing various fields of application other than an air conditioner, the rotary compressor provided with a compression part and a driving part and including a first case forming an external appearance of the rotary compressor, a second case provided inside the first case and provided with the compression part and the driving part at an inner side thereof, and a supporting member configured to support the second case and provided at an inner side of the first case.

A rotational impact tool including: a motor; a spindle; a hammer; a first resilient member; and an anvil. The motor generates a drive force. The spindle rotates in a rotating direction upon transmission of the drive force from the motor. The spindle has an axis extending in an axial direction that includes a first direction and a second direction opposite to the first direction. The hammer moves in the rotational direction and in the axial direction relative to the spindle to generate a rotational impact force. The first resilient member urges the hammer in the first direction. The anvil transmits the rotational impact force to an end bit. The rotational impact tool further includes a second resilient member. The second resilient member is disposed at a position radially outward of the first resilient member and is configured to abut the hammer when the hammer moves in the second direction.

The invention discloses a disassembling and assembling system and method for a power battery box with the side edge having a telescopic function. The disassembling and assembling system comprises a vehicle body bottom plate assembly, a battery box body located below the vehicle body bottom plate assembly and a battery box disassembly and assembly mechanism capable of enabling the battery box body to be installed below the vehicle body bottom plate assembly or enabling the battery box body to be unlocked from the lower portion of the vehicle body bottom plate assembly. The battery box body is provided with a drawer type telescopic structure which can be matched and fixed with a vehicle body bottom plate assembly; the drawer type telescopic structure comprises a fixed box body which is fixed on the side surface of the battery box body, a sliding box body which is matched with the fixed box body and can translate towards the inner side or the outer side of the fixed box body relative to the fixed box body, and a battery box positioning clamping groove matched with the sliding box body is formed in the bottom of the vehicle body bottom plate assembly. The battery box disassembling and assembling mechanism comprises a shifting fork frame capable of moving left and right and a shifting fork rod arranged on the shifting fork frame and used for driving the sliding box body to move left and right, and a shifting fork sliding groove and a shifting fork hole which correspond to each other, can be matched with the shifting fork rod and drive the sliding box body to slide are formed in the fixed box body and the sliding box body respectively.

A muffler of a vehicle includes a first muffler body so as to form a first chamber, at least a second muffler body including a housing, one end portion opened and the other end portion closed, wherein one of the second muffler bodies is fitted into the other end portion of the first member to form a second chamber and the other second muffler bodies are fitted into each other through the one end portions in series to form third chambers if more than one second muffler bodies are assembled, an inflow pipe to connect the outside with the first, second and/or third chamber by passing the one end portion of the first muffler body, and an outflow pipe to communicate the first, second, and/or third chamber with the outside by passing through the other end portion of the last second muffler body.

The invention relates to an armrest assembly structure and an automobile auxiliary instrment panel assembly. The armrest assembly structure comprises an armrest body, a buffer limiting structure and ahinge connecting structure. The buffer limiting structure comprises a buffer protruding structure and a buffer clamping structure which are arranged at the bottom of the front end of the handrail body, the buffer protruding structure is used for being correspondingly matched with the top face of the auxiliary instrument board body, and the buffer clamping structure is used for being correspondingly matched with the side wall of the auxiliary instrument board body in a clamping mode; a hinge connecting structure which comprises an upper hinge arm arranged on each of the two sides of the bottomof the rear end of the handrail body in a protruding mode, a lower hinge arm used for being connected with the two sides of the auxiliary instrument board body, and a friction damping rotating structure used for hinging the upper hinge arms and the lower hinge arms. According to the armrest assembly structure, the problems of troublesome unlocking operation and complex structure caused by configuring a lock catch structure at the front end of the handrail in related technologies can be solved.
