Abstract

The invention relates to the technical field of automobile assembly, in particular to a hydraulic buffer type bumper. The hydraulic buffer type bumper includes a cross bar, a reinforcing member, an ammonia gas chamber, a piston rod, a floating piston, a mechanical oil chamber, a throttling hole, and a buffer cylinder; the reinforcing member is arranged inside the cross bar; the front end of the reinforcing member is connected to a piston rod; the ammonia gas chamber and the mechanical oil chamber are formed in the piston rod; and the buffer cylinder is arranged on the front end of the mechanical oil cavity. The hydraulic buffer type bumper is simple in structure, can effectively utilize a gas buffer and liquid throttling damping working manner, and is stable in working characteristic.

Description

Hydraulic cushion type bumper
Technical field
The present invention relates to a kind of bumper, more particularly to a kind of hydraulic cushion type bumper.
Background technology
In automobile assembling, need to be fixedly connected between workpiece and workpiece, be so accomplished by a clamp system, existing clamp system operation inconvenience, while there is a problem of that clamping effect is not good.
The content of the invention
Present invention seek to address that drawbacks described above, there is provided a kind of hydraulic cushion type bumper.
In order to overcome defect present in background technology, the technical solution adopted for the present invention to solve the technical problems to be：This hydraulic cushion type bumper includes whippletree, reinforcement, ammonia chamber, piston rod, floating piston, mechanical oil pocket, throttle orifice and cushion dashpot, reinforcement is provided with the inside of whippletree, ammonia chamber and mechanical oil pocket are provided with the front end connection plunger stem flange bar of reinforcement, the front end of mechanical oil pocket is provided with cushion dashpot.
According to another embodiment of the invention, further include to be provided with floating piston between the ammonia chamber and mechanical oil pocket.
According to another embodiment of the invention, further include that the cushion dashpot is provided with throttle orifice.
The invention has the beneficial effects as follows：The simple structure of this hydraulic cushion type bumper, is effectively utilized gas buffer, the working method of liquid throttling damping, and operating characteristic is more stable.
Description of the drawings
With reference to the accompanying drawings and examples the present invention is further described.
Fig. 1 is the structural representation of the present invention；
Wherein：1st, whippletree, 2, reinforcement, 3, ammonia chamber, 4, piston rod, 5, floating piston, 6, mechanical oil pocket, 7, throttle orifice, 8, cushion dashpot.
Specific embodiment
Fig. 1 is the structural representation of the present invention, figure includes whippletree 1, reinforcement 2, ammonia chamber 3, piston rod 4, floating piston 5, mechanical oil pocket 6, throttle orifice 7 and cushion dashpot 8, the inner side of whippletree 1 is provided with reinforcement 2, the front end connection piston rod 4 of reinforcement 2, ammonia chamber 3 and mechanical oil pocket 6 are provided with piston rod 4, the front end of mechanical oil pocket 6 is provided with cushion dashpot 8.Floating piston 5 is provided between ammonia chamber 3 and mechanical oil pocket 6.Cushion dashpot 8 is provided with throttle orifice 7.
Reinforcement 2 in the inner side of whippletree 1 is connected by rubber blanket with the piston rod 4 of hydraulic cushion damper, piston rod 4 is hollow-core construction, built with floating piston 5, the hollow-core construction that piston rod 4 is constituted is divided into left and right two chamber by floating piston 5, the external cylindrical surface of piston rod 4 is slidably matched with cushion dashpot inner cylinder face, and machinery oil is communicated with piston rod right chamber in buffering hydraulic cylinder.When automobile and barrier collide, the impulsive force that bumper is subject to is passed on piston rod, and piston rod end moves right, and extruding hydraulic oil is flowed by throttle orifice to piston rod right chamber, promotes floating piston to be moved to the left, and is compressed ammonia.Viscous resistance when passing through throttle orifice using hydraulic oil absorbs the energy for clashing into, and the efficiency of energy absorption can be up to 80%.
The simple structure of this hydraulic cushion type bumper, is effectively utilized gas buffer, the working method of liquid throttling damping, and operating characteristic is more stable.
