the flat pin, it sets up in the outer container, the flat pin is in by cylinder, setting the left elliptic cylinder and the right elliptic cylinder at cylinder both ends are constituteed, a left side elliptic cylinder with the right elliptic cylinder all with the cylinder is tangent, left side elliptic cylinder part sets up in the outer container left side through-hole, right side elliptic cylinder follows pass the part setting in the outer container right side through-hole in the installation piece, be provided with the screw hole on the right side end face of right side elliptic cylinder, be provided with the through-hole on the right elliptic cylinder side, be provided with the spring bayonet lock in the through-hole.
Preferably, a threaded hole in the right elliptic cylinder of the flat pin is provided with a set screw.
Preferably, the flat pin is made of 45 gauge steel.
Preferably, the flat pin cylindrical part is connected with a hydraulic oil cylinder
Preferably, the flat pin is in clearance fit with the hydraulic oil cylinder.
The utility model discloses at least, include following beneficial effect:
1. a flat round pin is connected to A type landing leg, it is at operation car operation in-process, when a landing leg holding power of vehicle unbalance is zero, when having dangerous trend, the spring bayonet lock leaves micro-gap switch under the dead weight effect in the landing leg inner box, switch-on (or disconnection) vehicle control system circuit, the operation car stops the operation, avoids dangerous operation operating mode through control system.
2. A type landing leg connect cotter, can utilize the major axis minor axis after it adopts the cotter, after the landing leg stretches out completely, can avoid because of taking place welding deformation easily in the sub vehicle frame structure welding process, the landing leg four-point is uneven around causing, guarantees whole car level.
3. A type landing leg connect flat pin, its simple structure, reasonable in design is fit for using widely.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.
Drawings
Fig. 1 is a schematic structural view of an a-shaped leg connecting flat pin according to the present invention.
Fig. 2 is an a-shaped leg.
