Abstract
The present invention relates to a mechanical pivoting motionfrictionless checking brake, consisting of shell body, cam valve mechanism, crank link mechanism and hydraulic fluid. It is characterized by that the crank link mechanism and cam valve mechanism are installed inthe shell body, and the internal cavity of the shell body is filled up with hydraulic fluid, and said brake use the flow and resistance of the hydraulic fluid to move and control the reciprocating motion and brake of the crank link mechanism so as to implement the normal operation, deceleration or brake operation of the pivoting motion machine connected with the crank link mechanism. In the course of working said brake doesn't produce friction, and makes the temp. of working machine don't go up, so that said working achine is not easy to be damaged, its service life can be prolonged, and reliability and safety also can be raised.
Description
The present invention relates to a kind of braking device, especially mechanical rotation movement friction eceleration break.
Disclosed at present mechanical brake equipment all belongs to friction stopping device, because friction catch produces high temperature very easily at the volley, thereby can cause the damage of machinery, be lowered the working life of whole work component.Particularly use this friction stopping device on automobile, not only braking device self is at high temperature fragile, and the high temperature that friction produced of braking device is delivered on the tire, can cause tyre break, thereby cause traffic accident.Therefore, people urgently wish to have a kind of non-friction brake to be born.Chinese patent discloses " brake liquid-pressure control device " of a kind of use on vehicle, and this device is to promote the braking that friction plate carries out by hydraulic pressure, thereby is still a kind of friction stopping device, so it still exists the shortcoming of friction catch.
The purpose of this invention is to provide a kind of friction free speed-reducing brake for mechanical rotation movement, regulate and control the flow direction and the braking of hydraulic oil by the cam valve mechanism, thereby promote and control the to-and-fro motion and the braking of crankshaft ﹠ connecting, finally reach the purpose that in braking process, does not produce high temperature, do not damage running machinery.
The object of the present invention is achieved like this: make a kind of friction free speed-reducing brake for mechanical rotation movement that is made of cam valve mechanism, crankshaft ﹠ connecting, hydraulic oil, housing, its structure characteristic is: crankshaft ﹠ connecting and cam valve mechanism are installed in housing; The housing inner chamber is filled with hydraulic oil.
The crankshaft ﹠ connecting among the present invention and the mechanical connection that rotatablely moves, the cam valve mechanism is connected with manipulation machinery.When valve is in full-gear, the machinery that rotatablely moves rotates, rotation of the crankshaft group of crankshaft ﹠ connecting and drivening rod pump, and the to-and-fro motion of this connecting rod promotes hydraulic oil and also comes and goes in the housing inner chamber and flow, and hydraulic oil mobile is in unimpeded at this moment.When start handling machinery, when making valve in the cam valve mechanism by ashamed closing, the hydraulic oil in the housing inner chamber will grow out of nothing up to very big to the resistance that to-and-fro motion took place of the piston in the crankshaft group.This resistance passes to the machinery that rotatablely moves by connecting rod, crankshaft group etc. again, makes rotatablely moving by ashamed deceleration or be braked of the machinery that rotatablely moves.
The most significant advantage of the present invention is: do not produce friction in braking process, temperature can not raise, thereby running machinery is not fragile, but improve reliability and Security the working life of prolonged mechanical equipment.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is an overall structure schematic representation of the present invention;
Fig. 2 is the B-B sectional view of Fig. 1;
Fig. 3 is the A-A sectional view of Fig. 1.
As can be seen from Figure 1: the present invention mainly is made up of housing 1, cam valve mechanism 2, crankshaft ﹠ connecting 3, hydraulic oil 4, and its structure characteristic is: crankshaft ﹠ connecting 3 and cam valve mechanism 2 are installed in housing 1; Housing 1 inner chamber is filled with hydraulic oil 4.
From shown in Figure 2: the cam valve mechanism 2 the present invention is made up of short spacing circle 5, valve seat 6, valve 7, long spacing circle 8, Returnning spring 9, oil sealing end cap 10, camshaft 11, wherein 11 1 of camshafts are installed on the wall of housing 1, another wall of housing 1 is passed in the other end, and passes the oil sealing end cap 10 that is installed on this shell body wall again; Valve 7 is "T"-shaped, and it is positioned at the upper and lower of camshaft 11, is set with Returnning spring 9 on its "T"-shaped pin, the "T"-shaped valve seat 6 of wearing is sleeved on the housing 1.
From shown in Figure 3: the crankshaft ﹠ connecting 3 the present invention is made up of piston 12, piston ring 13, lining 14, wrist pin 15, connecting rod 16, main bearing cap 17, main axle bush 18, oil sealing end cap 19, crankshaft group 20, wherein piston 12 is installed in the middle and upper part of housing 1, is set with piston ring 13 on piston 12; Connecting rod 16 tops are installed in the piston 12 through lining 14 and wrist pin 15, and connecting rod 16 belows are sleeved on the crankshaft group 20, and main bearing cap 17 and main axle bush 18 are installed on the crankshaft group 20 of connecting rod 16 both sides; 20 1 of crankshaft groups are connected with connecting rod 16, and the other end is stretched out housing 1 and stretched out the oil sealing end cap 19 that is installed on this shell body wall.
Also can learn from Fig. 2 and Fig. 3: the camshaft 11 the cam valve mechanism 2 is through rocking arm 22 and manipulation mechanical connection, and the crankshaft group 20 in the crankshaft ﹠ connecting 3 is through the gear 21 and the mechanical connection that rotatablely moves.The utility model is performed such work:
1. when the valve 7 of break is standard-sized sheet with valve seat 6, hydraulic oil 4 in the housing 1 will in company with piston 12 one reciprocating, it is little of ignoring to the resistance of piston 12, so break goes to zero by connecting rod, 20 pairs of the crankshaft groups resistance that machinery produces that rotatablely moves, the machinery that rotatablely moves so be not subjected to keep normal operating condition under the resistance situation of break.
2. when the valve 7 of break is opened for part with valve seat 6, the mobile of hydraulic oil 4 in housing 1 inner chamber hindered, piston 12 will be subjected to the resistance of hydraulic oil 4 when moving back and forth like this, this resistance reduces the rotating speed that rotatablely moves that is attached thereto the machinery that rotatablely moves that connects by the gear 21 on connecting rod 16, the crankshaft group 20, reaches the purpose of deceleration.
3. when valve 7 and valve seat 6 are in buttoned-up status, hydraulic oil 4 in housing 1 inner chamber can't flow, the motion of 4 pairs of pistons 12 of hydraulic oil produces great resistance like this, this resistance all can not move piston 12 and connecting rod 16, crankshaft group 20 etc., therefore, being attached thereto the machinery that rotatablely moves that connects can not move, so reached the purpose of braking.
The present invention obtains obviously success through test, and it not only can be installed in the original friction-type brake apparatus of replacement on the automobile; But also can be used on other rotating machineries that need retarding braking, purposes is very wide.
