Abstract
The utility model relates to a damping device of an electric fire patrol vehicle. The damping device comprises a wheel steering knuckle, and a damper and a damping spring both arranged on the steering knuckle, wherein a connection support is arranged at the top of the damper; the damping spring is arranged between the connection support and a suspension bracket of the damper; a buffer rubber ring is fused with two ends of the damping spring. Through structure analysis on buffer performance of the conventional damping device and defining of a balance action value between the damper and the damping spring, the damping device provided by the utility model can ensure the reasonable designs on the buffer and bounce eliminating performance of the damping spring as well as the bounce eliminating performance of the damper, thereby greatly improve the running stability of the fire patrol vehicle and prolonging the service life of the damper.
Description
Technical field
The utility model relates to a kind of car shock mitigation system, is specifically related to a kind of electric firefighting scout vehicle shock absorption device.
Background technology
For improving running car stationarity; common meeting mounting shock absorber in automotive suspension; the current bumper adopting is on the market hydraulic damper mostly; its principle of work is in the time being subject to vibrations to occur relative motion between vehicle frame and vehicle bridge; piston up-down in bumper; fluid in bumper chamber just flows in another chamber through different spaces from a chamber repeatedly; the now intermolecular interior friction of the friction between hole wall and fluid and fluid forms dumping force to vibrations; making thump Conversion of Energy is the heat energy of fluid, then is absorbed and be dispersed in air by bumper.
Current automobile absorber generally includes and comprises oil storage cylinder barrel assembly, work cylinder barrel assembly, oil storage cylinder barrel assembly is provided with dust boot outward, in work cylinder barrel assembly, be provided with piston-rod assembly, the head of piston-rod assembly will bear pulling force and the pressure of automotive suspension, period of service is of a specified duration, and piston rod easily damages.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, and a kind of electric firefighting scout vehicle shock absorption device that reduces piston rod movement intensity is provided.
For achieving the above object, the technical scheme of taking is:
A kind of electric firefighting scout vehicle shock absorption device, comprise wheel steering joint, be arranged on bumper and damping spring on wheel steering joint, described bumper top is provided with connection bearing, damping spring is arranged on and connects between bearing and the suspension strut of bumper, and the two ends melting of damping spring has buffering rubber ring.
Described bumper is liquid damper, and piston rod is provided with organ protective cover outside the cylindrical shell of bumper.
The length sum of the buffering rubber ring at described damping spring two ends is 1:(5 ~ 7 with the ratio of damping spring total length).
Adopt technique scheme, obtained beneficial effect is:
The utility model is by the structural analysis of the cushion characteristic to existing shock absorption device, for defining of the equilibrium activity value between bumper and damping spring, thereby guarantee the rational Design on Plane of the buffering of damping spring and the elimination rebound performance of elimination rebound performance and bumper, not only greatly improve the stability of fire patrol car in operational process, and the service life of having improved bumper.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Sequence number in figure: 1 for wheel steering joint, 2 be bumper, 3 for damping spring, 4 for connect bearing, 5 for suspension strut, 6 for buffering rubber ring, 7 be organ protective cover.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Referring to Fig. 1, a kind of electric firefighting scout vehicle shock absorption device, comprise wheel steering joint 1, be arranged on bumper 2 and damping spring 3 on wheel steering joint 1, described bumper 2 tops are provided with and connect bearing 4, damping spring 3 is arranged on and connects between bearing 4 and the suspension strut 5 of bumper 2, the two ends melting of damping spring 3 has buffering rubber ring 6, described bumper 2 is liquid damper, outside the cylindrical shell of bumper 2, piston rod is provided with organ protective cover 7, the length sum of the buffering rubber ring 6 at described damping spring 3 two ends is 1:(5 ~ 7 with the ratio of damping spring 3 total lengths).
The utility model is by the structural analysis of the cushion characteristic to existing shock absorption device, for defining of the equilibrium activity value between bumper and damping spring, thereby guarantee the rational Design on Plane of the buffering of damping spring and the elimination rebound performance of elimination rebound performance and bumper, not only greatly improve the stability of fire patrol car in operational process, and the service life of having improved bumper.
