Abstract
The utility model relates to a steering axle safety lock, which comprises an air chamber seat and a lock seat, wherein the air chamber seat is welded on a bridge body of a steering axle. The utility model is characterized in that an air chamber is fixed on the air chamber seat; a vent hole is formed on the upper part of the air chamber; an air chamber piston rod is arranged in the air chamber; theair chamber piston rod is connected with a locking pin which is arranged in a vertical chute of the lock seat; and a lock plate is arranged in the lock seat, is perpendicular to the lock pin, is positioned in a lock seat space under the locking pin, and is fixedly connected with a steering transversal pull rod. The utility model solves the problems of labor wasting of self steering during backing-up and difficult wheel reversal before steering forward moving, and ensures the safety during steering forward moving.
Description
Technical field
The utility model relates to the safety lockset that a kind of Control of Automobile follow-up steering vehicle bridge turns to, specifically, and when being exactly a kind of automobile backward, by a kind of location lockset that turns to of reversing control.Belong to the vehicular spare parts technical field.
Background technology
Existing automobile following steering axle, toe-in value is all greater than 1mm, the wheel existing condition is pre-small post-large, be similar to " eight " font, it is stable to advance, but when reversing, the follow-up steering effort, commutate when advancing, wheel returns positive difficulty, that is to say that there is certain safety hazard in reversing automobile when travelling commutation.
The utility model content
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of vehicle bridge safety lockset that turns to is provided, to solve the problem that has safety hazard when reversing automobile travels commutation, and the safety when advancing of guaranteeing to commutate.
For solving above-mentioned technical matters, technical solution adopted in the utility model is, a kind of vehicle bridge safety lockset that turns to, it comprises and is welded on air chamber base and the lockset seat that turns on the vehicle bridge pontic, its air chamber is fixed on the air chamber base, air chamber top is provided with vent, is provided with the air chamber piston rod in the air chamber, and the air chamber piston rod is connected with locking pin; Locking pin is arranged in the vertical slideway of lockset seat, can slide up and down; Jam plate is arranged in the lockset seat, and is vertical with locking pin, is positioned at the lockset seat space of locking pin below, and jam plate is captiveed joint with tierod.
The above-mentioned vehicle bridge safety lockset that turns to also is provided with retracting spring in its air chamber, the one end is connected with the air chamber piston rod, and an end is connected with air chamber.
The above-mentioned vehicle bridge safety lockset that turns to, its jam plate is installed on the tierod, is one by the bolt clamped joint.
The vehicle bridge safety lockset that turns to of the present utility model, when reversing automobile travelled commutation, steering shaft rotated and drives the tierod side travel, thereby drives jam plate with the same moved further of intermediate rod.When reversing, in check gas enters air chamber along vent, promote the air chamber piston rod with the vertical slideway insertion jam plate of locking pin, therefore can in the corner 0-27 ° scope of steering shaft regulation, all can pin the tierod of captiveing joint in any position with jam plate along the lockset seat.
The vehicle bridge safety lockset that turns to of the present utility model can solve when reversing follow-up steering effort, and the wheel when advancing of commutating returns the problem of positive difficulty, the safety when advancing of guaranteeing to commutate.
Description of drawings
Below in conjunction with drawings and the specific embodiments the utility model is further described.
Fig. 1 is the structural representation that turns to the vehicle bridge safety lockset;
Fig. 2 is the constructional drawing of air chamber of the present utility model and lockset seat part.
The specific embodiment
As shown in Figure 1, a kind of vehicle bridge safety lockset that turns to, it is welded as a whole air chamber base 8, lockset seat 6 with pontic 1, air chamber 14 is fixed on the air chamber base 8, jam plate 9 is arranged in the lockset seat 6, and jam plate 9 is connected with tierod 19, fixes to clamp by bolt 20 to connect as one.
As shown in Figure 2, be fixed on the air chamber 14 on the air chamber base 8, its top is provided with vent 11, is provided with air chamber piston rod 10 in the air chamber 14, and air chamber piston rod 10 is connected with locking pin 7; Also be provided with retracting spring 18 in the air chamber 14, the one end is connected with air chamber piston rod 10, and an end is connected with air chamber 14; Locking pin 7 is arranged in the vertical slideway of lockset seat 6, can slide up and down; Jam plate 9 is arranged in the lockset seat 6, and is vertical with locking pin 7, is positioned at the corresponding space of the lockset seat 6 of locking pin 7 belows.
The automobile that this turns to the vehicle bridge safety lockset is installed, and when reverse travel commutated, the steering shaft of automobile rotated and drives tierod 19 side travels, thereby drives jam plate 9 with intermediate rod 19 same moved further.During reversing, in check gas enters air chamber 14 along vent 11, promote air chamber piston rod 10 with the vertical slideway insertion jam plate 9 of locking pin 7, therefore can in the corner 0-27 ° scope of steering shaft regulation, all can pin the tierod 19 of captiveing joint in any position with jam plate 9 along lockset seat 6.This turns to the vehicle bridge safety lockset, can solve when reversing follow-up steering effort, and the wheel when advancing of commutating returns the problem of positive difficulty, the safety when advancing of guaranteeing to commutate.
