Abstract
The invention relates to a fluid retarder and belongs to the machinery manufacturing industry. The fluid retarder is an auxiliary braking device of operating machinery, used for retardance braking of the operating machinery and installed on an operating system of the operating machinery. The fluid retarder is formed by connection of a transmission mechanism, a controller, a crank piston damper, a regulator and an auxiliary component, and the operating system of the operating machinery drives a piston of the crank piston damper to move through the transmission mechanism and the controller, so that a fluid medium of the system is forced to flow back and forth through the regulator to obtain a damping force, then the damping force is transmitted to form operating resistance of the operating system, and the operating machinery is forced to retard. The fluid retarder is quick in retardance and convenient to regulate.
Description
Under technical field: the present invention relates to a kind of fluid retarder, is a kind of mechanical complemental brake system that turns round, and is applicable to the slow braking of automobile in travelling, train, industrial operation equipment, descent control device, belongs to machine building industry.
Background technique: automobile, the slow braking of train adopts the braking of mechanical friction formula mostly, because heating value is large and the bad easy inefficacy of heat radiation, the big-and-middle-sized passenger-cargo carriage of minority has started to install additional complemental brake system, as friction-free engine braking, exhaust brake and retarder, what engine braking and exhaust brake all adopted is the vexed car principle of motor, slow power is little, slow slow, retarder mainly contains electric eddy current retarder and hydrodynamic retarder, what electric eddy current retarder adopted is generator principle, weak heat-dissipating, not lasting slowly, what hydrodynamic retarder adopted is fluid coupling principle, utilize the centrifugal motion of liquid in two semiaxis to obtain damping force, pressure vehicle is slow, its complex structure, make inconvenient maintenance, running industry equipment slow, mostly the faint system of the dependence equipment nature that rubs itself is slow, can not realize fast and stopping, some large-scale fan rotors after power cut because inertia for a long time all can not stop, bring potential safety hazard to emergency case and overhaul of the equipments, minority mini-plant is also only provided with band-type brake the friction type break, descent control device adopts mechanical friction to brake slow falling more, minority adopts that hydraulic shock absorber is slow to fall, because its hole piston is encapsulated in piston cavity, damping force is non-adjustable, use inconvenience.
Summary of the invention: the technical problem to be solved in the present invention is, for the machinery that turns round installs a kind of retarder additional, can provide more greatly for it, more lasting and easy to adjust slow power, make its can be sooner, slow more freely, assurance personnel and device security.Its technological scheme adopting is to fasten and install a kind of fluid retarder additional in the mechanical running of running, this device is connected to form by driving mechanism, controller, crank dashpot, regulator, auxiliary element, the running system of turning round mechanical drives crank dashpot piston movement by driving mechanism, controller, force system fluid medium flow back and forth and obtain damping force through regulator, then transmit the running resistance that forms running system, force running machinery slow.This beneficial effect of the invention be slow power greatly, fast, simple in structure slowly.
Embodiment: the present invention is further described below in conjunction with three embodiments.
Embodiment one: on truck drive shaft, increase a pair of transmission, be connected with crank dashpot by clutch, the other end of bent axle is connected with radiator, piston is equal angle, radial plane and arranges, be connected on the same eccentric shaft shoulder by connecting rod, each piston cavity is connected with flowing medium chamber by a throttle valve, clutch closes when work, truck drive shaft just can drive crank dashpot piston movement by driving mechanism, force system fluid medium flow back and forth and obtain damping force through throttle valve, the aperture of adjusting throttle valve just can change the size of damping force, then transmit the rotational resistance that forms transmission shaft, pressure vehicle is slow.
Embodiment two: on truck drive shaft, increase a pair of transmission, be connected with crank dashpot by clutch, the other end of bent axle is connected with radiator, piston is radially different surface beeline and arranges, each piston cavity is directly connected with flowing medium chamber by a throttle valve, piston rod is connected with the eccentric shaft shoulder that radially the equal angle of antarafacial distributes respectively, clutch closes when work, truck drive shaft just can drive damper piston motion by driving mechanism, force system fluid medium flow back and forth and obtain damping force through throttle valve, the aperture of adjusting throttle valve just can change the size of damping force, then transmit the rotational resistance that forms transmission shaft, pressure vehicle is slow.
Embodiment three: on the rope of high-rise descent control device, increase a pair of transmission, rope can drive major-minor to rotate, be connected with crank dashpot from secondary, piston is radially different surface beeline and arranges, every adjacent two piston cavity are connected by throttle valve, piston rod is connected in respectively on the eccentric shaft shoulder of two Central Symmetry positions, in chamber, be filled with flowing medium, when use, people, thing drives the piston movement of crank dashpot under Action of Gravity Field by rope and transmission, system fluid medium is pressed to another piston cavity from a piston cavity through throttle valve repeatedly, the aperture of adjusting throttle valve just can change the size of damping force, force people, thing declines slowly.
Claims (1)
1. a fluid retarder, it is a kind of mechanical complemental brake system that turns round, this device is arranged on the mechanical running of running and fastens, connected to form by driving mechanism, controller, crank dashpot, regulator, auxiliary element, it is characterized in that the running system of turning round mechanical drives crank dashpot piston movement by driving mechanism, controller, force system fluid medium flow back and forth and obtain damping force through regulator, then regulate, transmit the running resistance that forms running system, force running machinery slow.
