Face mechanism freedom calculation formula：N=3N-2P-C=3*6-2* (6+2) -0=2, side：Mechanism freedom of movement N=2, you can real
It now brakes, alleviates.
The operation principle of the car retarder of the present embodiment is as follows：Vehicle reducer-actuating unit when not working usually at
In retarder location.After the vehicle to get off on hump enters reducer track circuit, after control system sends out order as needed, in liquid
Under the action of pressure system, which starts to work, if implementing to brake to vehicle, executing agency is in column
Under the action of filling in oil cylinder, plunger 3 is overhanging to be lifted clamp body and swings and rise, and two braking rails are in retarder location working condition, and at this time two
Braking rail opening size is less than wheel thickness.When vehicle enters retarder, wheel squeezes braking rail, plunger cylinder pressure liter
Height is implemented to brake to vehicle, and vehicle forward, the speed of vehicle is prevented to decline.When car speed, which reaches control, to be required, control system
System sends out alleviation order, and the rapid pressure release discharge of the oil in plunger cylinder, 3 clamp body of plunger and braking rail are quick under the effect of gravity
Decline moves to alleviating position together, and vehicle passes through.
The course of work and mode are alleviated in braking：Before vehicle enters reducer actuator, control system sends out braking life
After order, vehicle reducer-actuating unit is in original braking operation position.After vehicle enters reducer actuator, if it is small
Group vehicle, executive device can keep this position constant, and after vehicle enters reducer actuator, wheel squeezes braking rail, braking rail
Wheel is reacted on, brake force is applied to wheel, realizes and slows down.If the vehicle into reducer actuator be in, big group
Vehicle is carried out " put head and block tail "；Vehicle is moved ahead with certain speed, and reducer actuator wouldn't carry out braking to former vehicles,
When putting head amount, which reaches control, to be required, control system order reducer actuator moves to original working position, implements to vehicle
Braking, until speed reaches control and requires, at this moment control system order executive device, which moves to, alleviates operating position, and vehicle is smooth
Pass through reducer actuator.
Braking function is repeated to realize：If being a group vehicle of growing up into reducer actuator, dress is executed after reaching constant speed
It sets and has alleviated, but accelerate due to circuit or wind-force etc., when car speed is more than constant speed, at this moment need to implement to repeat to make
It is dynamic；As long as control command provides, this vehicle reducer-actuating unit will reach braking operation position from alleviation working position rapidly, right
Vehicle is implemented to repeat to brake, and the speed of vehicle is made to drop to fixed speed again, completes to repeat braking function.
The conversion of brake force:This executive device coordinates with hydra-electric system, it can be achieved that the level conversions such as brake force.Work as braking
When power order of magnitude is converted, the machine performance of executive device is constant, and only Plunger oil in-cylinder pressure size is according to control command need
It changes.Since mechanical movement does not occur, the conversion time of brake rating is the electric elements break-make response time, anti-
Should be quite rapid, therefore this executive device speed regulation accuracy is higher.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
The specific implementation of the present invention is confined to these explanations.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the present invention's
Protection domain.
