Abstract
The invention provides a kind of method that damping resistance solves wheel machine brake, when rotating wheel mechanisms that needs brake, the rotation exported by gear mechanism connects damping oil cylinder by synchronizer, brake fluid is pressed into the folding of control valve and the folding of check valve in control cylinder, control cylinder by cylinder movement, and the oil in damping oil cylinder can not smoothly be input into, produce resistance, the piston movement in damping oil cylinder is prevented, so as to prevent pinion rotation, the purpose of brake is reached.And the brake of single-wheel can be realized by controlling the folding of check valve, distribute the different road conditions required different brake weight of each wheel.
Description
Technical field：The invention belongs to mechanical field wheel machine brake system, it is related to provide resistance by damping oil cylinder
Realize the purpose of brake.
Technical background：Current wheel machine brake uses brake block and produces resistance by rubbing with brake shoe, makes to turn
Dynamic wheel parking, necessarily causes frictional heating, abrasion, reduces the reliability of brake system, increases the cost of maintenance, and receive
The reduction of such environmental effects coefficient of friction, influences braking effect.The present invention provides resistance by damping oil cylinder, reaches the mesh of brake
's.Do not produce frictional force, thus can solve because friction belt come the drawbacks of, while no longer needing the boost pump that brakes, reduce brake
Physical demands.And improve the Reliability ＆ Maintainability of brake system.
The content of the invention：The invention provides a kind of method that damping resistance solves wheel machine brake, when rotating wheel mechanisms that is needed
When braking, the rotation exported by gear mechanism connects damping oil cylinder by synchronizer, and cylinder movement is pressed into brake fluid and controls
By folding control valve in oil cylinder, control cylinder, the oil in damping oil cylinder can not smoothly be input into, and produce resistance, prevent damping oil
Piston movement in cylinder, so as to prevent pinion rotation, reaches the purpose of brake.When brake hard is needed, in order to prevent locking,
Control two oil pockets at valve two ends that adjustable check valve is installed in control cylinder, it is to avoid brake locking, and reduce impulsive force,
Protection mechanical mechanism.Control cylinder can be also turned on the damping oil cylinder for needing to brake several wheels, control each to damp by check valve
Oil cylinder enters the pressure oil of control cylinder so as to the brake weight for realizing controlling single wheel different, it is adaptable to each needed for different road conditions
The different brake weight of individual wheel.Check valve can be with electric control, the different brake weight of computer control distribution.
Brief description of the drawings：Fig. 1 is damping brake system schematic diagram
Specific embodiment：Detent housing (1) is fixed on axletree (3), fixing vehicle wheel on gear (2), and passed through
Bearing (14) is installed in wheel shaft (3).When wheel needs braking, pedal (15) is stepped on, first with reference to synchronizer (12), then passed through
Control valve (8) closing control oil cylinder connects oil pocket (7), and brake fluid can not be passed through by efferent duct (5), produces resistance, resistance
Only piston (9) straight reciprocating motion, prevents gear (13) from rotating by connecting rod (11) bent axle (10), so as to prevent gear (2) from turning
It is dynamic, reach the purpose of brake.When brake hard, synchronizer (12) is combined first, and control valve (8) is closed rapidly, is produced huge
Resistance, now in order to prevent take turns locking, in control cylinder (7) unidirectional regulating valve (6) ensure certain pressure under automatically turn on,
While ensureing to obtain the skid resistance for needing, moreover it is possible to avoid locking and huge impulsive force, it is ensured that the reliability service of mechanism.
Control cylinder (7) can access need simultaneously control several wheels, by defeated oil-inlet end install check valve (16), by electric control according to
The different single control damping oil cylinders of road conditions, are that each wheel obtains different skid resistances, realize that a control cylinder (7) can be simultaneously
The different damping brake of the several wheels of control.
The composite can be widely applied to the brake gear of the wheel machines such as aircraft wheel, train wheel, automotive wheels.Wheel can be reduced to stop
The cost of car system, improves the reliability and maintainability of brake system.
