Abstract
The utility model discloses an operating device to connect the tractor and a trailer. The utility model comprises a shell, an union joint, a connector, a pump and a shock absorber; the shell is movably connected with the connecting shell; the shell is connected with the pump and the cylinder of the shock absorber; when the tractor brakes, the shell slides with the steel component of the connecting shell; the cylinder of the pump produces the oil pressure to make the branch pump produce oil pressure and realize the synchronous brake and slow down the steel crash; the shock absorber piston can move with the cylinder; and the braking liquid buffers through the pressure blocking hole to reduce the crash between the tractor and the trailer. Moreover the utility model can be detached from the tractor and is convenient and quick to be connected.
Description
Technical field
The utility model relates to the connecting device of tractor truck and trailer, specifically is to handle the tractor truck glancing impact that in-house synchronous generation oil pressure is realized trailer and a kind of steering unit that draws synchronous braking.
Background technology
Existing tractor truck, as lorry, locomotive and being connected of trailer be by a latch the be rigidly connected body and the draw bar of tractor truck and trailer.At the tractor truck glancing impact, impulsive force is bigger, can not actv. be braked by trailer again, and therefore vibrations are big, and safety performance is relatively poor, influences this mechanism and tractor truck, the service life of trailer.
Summary of the invention
The utility model is in order to improve the disadvantage that existing steering unit is rigidly connected and is produced, and design provides a kind of at the tractor truck glancing impact, reduces the impulsive force of trailer, realizes the steering unit of synchronous braking.
To this, the utility model proposes new technical conceive imagination to prior art: it includes body skin and is connected housing, connector, master cylinder, bumper.Described connector includes locking plate, locking plate, and stage clip is adjusted screw rod, spherical folder; Described master cylinder includes the master cylinder cylinder body, total pump piston, damping spring and fluid (oil) mouth; Described bumper includes shock absorber piston, bumper cylinder body, damping hole.The master cylinder cylinder body with subtract device device cylinder body and be connected body skin, total pump piston and dashpot piston, be connected with carriage on the body skin respectively, total pump piston socket damping spring, connector joins with connecting housing, its technical characterstic is: body skin is movably connected in the waist shaped hole that connects housing with connecting housing by roller shaft and roller, master cylinder cylinder body tail end has fluid (oil) mouth, on the bumper cylinder body damping hole is arranged, the sphere folder of connector is connected the adjustment screw rod respectively with locking plate, adjust screw rod socket stage clip, head end connects locking plate.
The utility model is compared with the bindiny mechanism of existing rigidity, and the positive technique effect that presents has: connect housing with the tractor truck bonded assembly and be connected with the body skin rolling, the tractor truck glancing impact forms buffer action, reduces the rigid collision of tractor truck and trailer; The effect of inertia of trailer makes the braking liquid (oil) in the total pump piston compression cylinder, and braking liquid is passed in the triler brake wheel cylinder from fluid (oil) mouth, makes trailer and tractor truck synchronous braking; Shock absorber piston and bumper cylinder body produce relative motion at glancing impact, and the braking liquid in the bumper cylinder body produces shock damping action by damping hole, plays the damping, buffering effect; The sphere folder of connector is adjusted screw rod by locking plate, and the driving device that stage clip constitutes realizes that folding splits, and is convenient, laborsaving.
