Abstract
The present invention discloses a vibration damper for a hydraulic braking device of vehicles, which is used for reducing vibration of motor vehicles. The present invention comprises a barrel body, the inner of the barrel body is provided with a floating piston, holes are arranged on the barrel body at the side of the floating piston, and a cavity, which is formed by the barrel body and the floating piston and in which an elastic element is arranged, is arranged on the barrel body at the other side of the floating piston; the elastic element is a combined butterfly-shaped spring, the elastic element is provided with an elastic adjusting device which is composed of an adjusting bolt and a presser bit, and the adjusting bolt is in screw connection with the barrel body. The present invention can absorb, release and consume vibration energy generated during brake and reduce vibration generated during hydraulic brake, and the present invention is low in cost.
Description
The present invention relates to a kind of shock attenuation unit, especially a kind of shock absorber that is used for hydraulic brake device of vehicle.
Vehicle is at the glancing impact of running at high speed, may cause control wheel, unacceptable vibration takes place in position such as brake pedal and driver's chair, its major cause is to cause wearing and tearing inhomogeneous because the brake disc assembling is improper, and factors such as the corrosion of brake disc and thermal stress deformation cause brake disc uneven, certainly will cause the surging of oil pressure in the brake cylinder like this, cause the serious pulsatile change of lock torque, this vibration that is taken place by the lock torque variation will inevitably evoke certain response in suspension system and control loop.Cause vibration of vehicle in order to reduce and to suppress by braking, the method that adopts is to improve the design of chassis structure system usually, makes its reduction vibratory response, stops this vibration to connect rod member by vehicle frame and is delivered to control loop.Usually adopt the increase rod member to connect the lining damping method and reduce transmission of vibration.For example, common rubber bush is replaced with hydraulic bushing, can improve the torsional oscillation response of driving wheel effectively.But the price of hydraulic bushing is 9 times of plain bushing price, is difficult to apply.
Goal of the invention of the present invention is to provide a kind of can reduce vibration and its cheap shock damper for hydraulic brake device of vehicle that hydraulic braking causes effectively.
The present invention adopts following technical scheme to realize its goal of the invention:
The present invention is a kind of shock damper for hydraulic brake device of vehicle that is used to reduce the power actuated vehicle vibration, comprise cylindrical shell 1, in cylindrical shell 1, be provided with floating piston 2, on the cylindrical shell 1 that is positioned at floating piston 2 one sides, be provided with hole 4, in the cavity 11 that forms by cylindrical shell 1 and floating piston 2 of the opposite side of floating piston 2, be provided with elastic element 3.
Compared with prior art, the present invention has following advantage:
1. as previously mentioned, the vibration that causes during hydraulic braking is because due to the irregular wear of brake disc, wear and tear few place relatively the projection, wearing and tearing place how is recessed relatively, therefore the suffered braking antagonistic force of braking clamp in the hydraulic brake system changes, produce vibration, the present invention can absorb when braking oil pressure increases, consumed energy, or the energy that output is put aside when braking oil pressure reduces, promptly when braking oil pressure was excessive, fluid entered oil pocket 12 and promotes floating piston 2 by hole 4, elastic element 3 pressurized accumulation of energys, simultaneously, portion of energy consumption; When braking oil pressure diminishes, the present invention is again to the brake system oil transportation, give off energy, simultaneously, portion of energy is consumed, so, the present invention has reduced effectively because the vibration that hydraulic braking produces has improved the vehicle braked performance, simultaneously, because cost of the present invention also only is about 10 yuan of Renminbi, so have cheap advantage.
2. because elastic element of the present invention has adopted belleville spring, it can reduce axial volume of the present invention, make it be more suitable for using in the small space in vehicle, it is little to have volume, after the advantage of compact conformation, particularly the present invention had adopted the combination belleville spring, it becomes stiffness characteristics made axial volume of the present invention further reduce, the requirement of vibration damping when more meeting hydraulic braking helps using the present invention on vehicle.
3. because the present invention is provided with elastic adjusting device, and the user can make adjustment to the elasticity of elastic element according to the concrete needs of own vehicle, make it more help reducing the vibration that glancing impact produces.
Fig. 1 is the structural representation of the embodiment of the invention.
With reference to the accompanying drawings, embodiment of the present invention being done one describes in detail:
The present invention is a kind of shock damper for hydraulic brake device of vehicle that is used to reduce the power actuated vehicle vibration, comprise cylindrical shell 1, in cylindrical shell 1, be provided with floating piston 2, on the cylindrical shell 1 that is positioned at floating piston 2 one sides, be provided with hole 4, in the cavity 11 that forms by cylindrical shell 1 and floating piston 2 of the opposite side of floating piston 2, be provided with elastic element 3, above-mentioned elastic element 3 can be a cushion, it also can be spring, spring then adopts belleville spring, for further dwindling axial volume of the present invention, more help the use on vehicle, elastic element 3 can adopt superimposed combination for combination belleville spring 3, combination belleville spring, involutory combination or composite combined, for further improving effectiveness in vibration suppression, elastic element 3 is provided with elastic adjusting device 5, and elastic adjusting device 5 is made up of adjustable bolt 51 and compressing tablet 52, and adjustable bolt 51 is threaded with cylindrical shell 2.
