Description
本发明涉及一种减振装置，尤其是一种用于车辆液压制动装置的减振器。The invention relates to a shock absorber, in particular to a shock absorber for a vehicle hydraulic brake device.
车辆在高速行驶制动时，可能会引起驾驶盘，制动踏板和司机座椅等部位发生不能接受的振动，其主要原因是由于制动盘装配不当造成磨损不均匀，以及制动盘的腐蚀和热应力变形等因素造成制动盘凹凸不平，这样势必造成制动缸内油压的强烈波动，导致制动力矩严重的脉动变化，这种由制动力矩变化发生的振动必然会在悬架系统和驾驶系统激起一定的响应。为了减少和抑制由制动引起车辆的振动，通常采用的方法是改善底盘结构系统的设计，使其弱化振动响应，阻止这种振动通过车架连接杆件传递到驾驶系统。通常采用增加杆件连接衬套阻尼方法来减少振动的传递。例如，把普通的橡胶衬套用液压衬套代替，可以有效地改善驾驶轮的扭振响应。但是，液压衬套的价格是普通衬套价格的9倍，难以推广应用。When the vehicle brakes at high speed, it may cause unacceptable vibrations in the steering wheel, brake pedal and driver's seat. The main reason is that the brake disc is not properly assembled, which causes uneven wear and corrosion of the brake disc. Factors such as thermal stress and deformation cause the brake disc to be uneven, which will inevitably cause strong fluctuations in the oil pressure in the brake cylinder, resulting in severe pulsating changes in the braking torque. The system and the driving system provoke a certain response. In order to reduce and suppress the vibration of the vehicle caused by braking, the usual method is to improve the design of the chassis structure system to weaken the vibration response and prevent this vibration from being transmitted to the driving system through the connecting rods of the frame. The method of increasing the damping of the connecting bushing of the rod is usually used to reduce the transmission of vibration. For example, replacing ordinary rubber bushings with hydraulic bushings can effectively improve the torsional vibration response of the driving wheel. However, the price of hydraulic bushings is 9 times that of ordinary bushings, making it difficult to popularize and apply.
本发明的发明目的在于提供一种能够有效地降低液压制动引起的振动且其造价低廉的车辆液压制动装置用减振器。An object of the present invention is to provide a shock absorber for a vehicle hydraulic brake device that can effectively reduce vibration caused by hydraulic brakes and is inexpensive.
本发明采用如下技术方案来实现其发明目的：The present invention adopts following technical scheme to realize its object of the invention:
本发明即一种用于减小机动车辆振动的车辆液压制动装置用减振器，包括筒体1，在筒体1内设有浮动活塞2，在位于浮动活塞2一侧的筒体1上设有孔4，在浮动活塞2的另一侧的由筒体1与浮动活塞2形成的空腔11内设有弹性元件3。The present invention is a vehicle hydraulic brake shock absorber for reducing the vibration of a motor vehicle, comprising a cylinder 1, a floating piston 2 is arranged inside the cylinder 1, and a A hole 4 is provided on the top, and an elastic element 3 is provided in the cavity 11 formed by the cylinder 1 and the floating piston 2 on the other side of the floating piston 2 .
与现有技术相比，本发明具有如下优点：Compared with prior art, the present invention has following advantage:
①如前所述，液压制动时引起的振动是由于制动盘的不均匀磨损所致，磨损少的地方相对凸起，磨损多的地方相对凹下，液压制动装置中的制动钳夹所受的制动反作用力因此而发生变化，产生振动，本发明可以在制动油压增大时吸收、消耗能量，或在制动油压减小时输出积蓄的能量，即当制动油压过大时，油液通过孔4进入油腔12并推动浮动活塞2，弹性元件3受压蓄能，同时，部分能量消耗；当制动油压变小时，本发明又向制动系统输油，释放出能量，同时，部分能量被消耗，所以，本发明有效地降低了由于液压制动产生的振动，提高了车辆的制动性能，同时，由于本发明的造价也仅为人民币10元左右，故具有造价低廉的优点。①As mentioned above, the vibration caused by hydraulic braking is caused by the uneven wear of the brake disc. The place with less wear is relatively raised, and the place with more wear is relatively concave. The brake caliper in the hydraulic brake device Therefore, the brake reaction force on the clamp changes and produces vibration. The present invention can absorb and consume energy when the brake oil pressure increases, or output the accumulated energy when the brake oil pressure decreases, that is, when the brake oil When the pressure is too large, the oil enters the oil chamber 12 through the hole 4 and pushes the floating piston 2, the elastic element 3 is pressed to store energy, and at the same time, part of the energy is consumed; Oil releases energy, and at the same time, part of the energy is consumed. Therefore, the present invention effectively reduces the vibration caused by hydraulic braking and improves the braking performance of the vehicle. At the same time, the cost of the present invention is only RMB 10 Left and right, so it has the advantage of low cost.
②由于本发明的弹性元件采用了蝶形弹簧，它可以减小本发明的轴向体积，使其更适合在车辆内的狭小空间中使用，具有体积小，结构紧凑的优点，特别是本发明采用了组合蝶形弹簧后，其变刚度特性使得本发明的轴向体积进一步减小，更符合液压制动时减振的要求，有利于在车辆上使用本发明。②Because the elastic element of the present invention adopts a butterfly spring, it can reduce the axial volume of the present invention, making it more suitable for use in a small space in a vehicle, and has the advantages of small size and compact structure, especially the present invention After adopting the combined belleville spring, its variable stiffness characteristic makes the axial volume of the present invention further reduced, which is more in line with the requirement of vibration reduction during hydraulic braking, and is beneficial to use the present invention on vehicles.
③由于本发明设有弹性调整装置，使用者可以根据自己车辆的具体需要，对弹性元件的弹性作出调整，使其更有利于减小制动时产生的振动。③ Since the present invention is provided with an elastic adjustment device, the user can adjust the elasticity of the elastic element according to the specific needs of his own vehicle, so that it is more conducive to reducing the vibration generated during braking.
