Abstract
The utility model relates to the field of mechanical interlocking and discloses a swing lock for an automobile chassis. The chassis comprises a front frame and a rear frame; the swing lock comprises a pin shaft and a cylinder sleeving the pin shaft; one end of the pin shaft is inserted into the rear frame, while the other end of the pin shaft is connected with a braking vane by virtue of a brake cable; an annular projection is arranged in the middle part of the pin shaft; the cylinder is divided by the annular projection into two chambers; an elastic element is arranged in the chamber close to the brake cable. The swing lock for the automobile chassis has the advantages that the braking vane is operated to drive the pin shaft to slip off or slip into the rear frame of the automobile chassis, and therefore, the rotation of the rear frame of the automobile chassis is controlled, no other element needs to be added and the production cost is low; the swing lock for the automobile chassis is easy to operate.
Description
Technical field
The utility model relates to mechanical interlocking field, refers to especially a kind of pendulum lock for car chassis.
Background technology
At present, car chassis lock be generally utilize manually, hydraulic pressure, electronic mode drives bearing pin motion.If adopt hydraulic pressure or electronic mode to control bearing pin, will inevitably increase components and parts, increase cost.And adopt manual mode, be not unfavorable for again operation.
Utility model content
The purpose of this utility model is to provide a kind of pendulum lock for car chassis, the bearing pin in this pendulum lock skid off or slip into vehicle frame after car chassis in, control the rotation of vehicle frame after car chassis.
To achieve these goals, the utility model has adopted following technical scheme: a kind of pendulum lock for car chassis, described chassis comprises front vehicle frame and rear vehicle frame, this pendulum lock comprises a bearing pin and is sheathed on a cylinder body in bearing pin outside, rear vehicle frame is inserted in described bearing pin one end, and the other end is connected with braking vane by brake cable, and described bearing pin middle part is provided with an annular projection, this annular projection is divided into two chambers by cylinder body, near in a chamber of brake cable, is being provided with an elastic component.
Further, described bearing pin is provided with an aperture in the one end being connected with brake cable, and described brake cable is fixed through aperture and bearing pin.
Further, described elastic component is post spring, and this post spring is sheathed on outside bearing pin.
Further, described cylinder body has been provided with oil nozzle.
Further, described cylinder body is located in front vehicle frame.
The beneficial effects of the utility model are: adopt after said structure, by operation braking vane, drive bearing pin to skid off or slip into vehicle frame after car chassis, and then control the rotation of vehicle frame after car chassis, needn't increase other components and parts, productive costs is low, easy to operate.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment technical scheme, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only that the utility model is in order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of pendulum lock for car chassis as shown in Figure 1, described chassis comprises front vehicle frame and rear vehicle frame 7, this pendulum lock comprises a bearing pin 3 and is sheathed on a cylinder body 6 in bearing pin 3 outsides, described cylinder body 6 is located in front vehicle frame, bearing pin 3 two ends extend to respectively outside cylinder body 6, and rear vehicle frame 7 is inserted in bearing pin 3 one end, be flexibly connected with rear vehicle frame 7, the other end is connected with braking vane 1 by brake cable 2, so only needs pin to step on braking vane 1, drives bearing pin 3 motions, bearing pin 3 is skidded off, separated with rear vehicle frame 7, rear vehicle frame 7 can freely swing, latch-release.
Described bearing pin 3 middle parts are provided with an annular projection 8, and this annular projection 8 is divided into two chambers by cylinder body 6, near in a chamber of brake cable 2, are being provided with an elastic component 5.In the present embodiment, described elastic component 5 is post spring, and this post spring is sheathed on outside bearing pin 3, annular projection 8 and the mutual squeezing rod spring of cylinder body 6 sidewall.
Step on after braking vane 1, the power that brake cable 2 imposes on bearing pin 3 is greater than the tightening force of post spring, drives bearing pin 3 motions, and bearing pin 3 skids off from rear vehicle frame 7, latch-release, thus after car chassis, vehicle frame 7 can freely rotate; After braking vane 1 unclamps, bearing pin 3, under the effect of post spring tightening force, slip into after car chassis in vehicle frame 7, thereby behind restricting vehicle chassis, vehicle frame 7 freely rotates, vehicle frame 7 after locking.
Wherein, described bearing pin 3 is provided with an aperture in the one end being connected with brake cable 2, and described brake cable 2 is fixing with bearing pin 3 through aperture, brake cable 2 can be firmly and bearing pin 3 fix.
Wherein, described cylinder body 6 has been provided with oil nozzle 4.This oil nozzle 4 is used to bearing pin 3 and post spring to increase lubricating oil, to avoid the stuck not problem of return of bearing pin 3 that causes of post spring.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
