Abstract
The utility model relates to a vehicle wheel distance movement limiting and locking device. The device comprises a motor, a limit block I and a limit block II, wherein the motor enables a suspension frame to move; the limit block I is arranged on a vehicle body; the limit block II is arranged on the movable suspension frame; a pressure sensor is arranged on each of the limit block I and the limit block II; a first locking groove is formed between the limit block I and the vehicle body; a second locking groove is formed between the limit block II and a suspension frame bracket; a locking device is arranged at the upper end of each of the limit block I and the limit block II. By the vehicle wheel distance movement limiting and locking device, the suspension frame is limited and automatically locked in a moving process, the suspension frame cannot depart from the vehicle body, the freedom degree of the suspension frame is limited, the safety of a vehicle is guaranteed after the wheel distance is changed, and the probability of accidents is reduced.
Description
Technical field
The utility model relates to a kind of Locking Device, relates in particular to a kind of automobile wheel track and moves limiting lock locking apparatus.
Background technology
Along with expanding economy, the raising of people's living standard, automobile has become one of important tool that people ride instead of walk.All automobile accelerates current automotive research, the raising of the aspect performance such as steady and cross-country being devoted to, tradition wheelbase fixed type automobile is subject to the power of the restriction driving engine of ground attaching coefficient to can not get fully playing when starting is accelerated, thereby has affected the acceleration capability of starting low-speed stage.So occurred the variable automobile of some wheelbases, and that the variable automobile of these wheelbases needs in wheelbase change procedure is spacing, needs locking to limit the degree of freedom of suspension after spacing.
Chinese patent notification number CN2625200Y, on July 14 2004 day for announcing, name is called wheel base adjustable automobile, includes vehicle body, power system, running gear, operating system; Described running gear has a Wheel space adjusting device that regulates front wheel spindle and hind axle distance, and it comprises: a groove-shaped frame that is both an automotive frame part, a set of can be in groove-shaped frame the bogie wheel of scroll forward and backward; A set of support column being flexibly connected with the bolster of bogie wheel, this support column is arranged on automobile axle; The upper end medial surface of support column is fixed with and can makes semiaxis, back axle along the nut seat of vehicle body fore-and-aft direction translation by support column, the screw thread transmission that this nut seat consists of driving nut and screw mandrel, and the other end is flexibly connected and locates with crossbeam.Its weak point is, infinite place and Locking Device after wheelbase changes.
Utility model content
The purpose of this utility model be for solve existing wheel base adjustable automobile adjusting shaft apart from time compared with the defect of difficult spacing and locking, provide a kind of automobile wheel track to move limiting lock locking apparatus.
To achieve these goals, the utility model is by the following technical solutions:
A kind of automobile wheel track moves limiting lock locking apparatus, comprise the motor that suspension is moved, also comprise the limiting stopper first being arranged on vehicle body and be arranged on the limiting stopper second on removable suspension, difference setting pressure sensor in limiting stopper first and limiting stopper second, between limiting stopper first and vehicle body, be provided with the first locked groove, limiting stopper second and suspension strut are provided with the second locked groove, and limiting stopper first and limiting stopper second upper end are respectively equipped with Locking Device.In the technical program, in suspension moving process, limiting stopper first and the touching of limiting stopper second, pressure sensor is passed to motor by signal, suspension is stopped mobile, motor is passed to vehicle-mounted ECU by signal, and then feed back to Locking Device, Locking Device triggers locking, suspension is fixed on vehicle body, thereby has realized the spacing and automatic locking being suspended in moving process, make suspension can not depart from vehicle body, and limit its degree of freedom, guarantee that wheelspan changes the safety of rear vehicle, the possibility that minimizing accident occurs.
As preferably, pressure sensor is connected with motor.
As preferably, the first locked groove is T font, the inverted T-shape of the second locked groove for matching with the first locked groove.In the technical program, suspension move spacing after, the first locked groove and the second locked groove synthesize I-shape, to match with the dead bolt of Locking Device.
As preferably, Locking Device comprises housing, locking spring, electromagnet and dead bolt, and Locking Device is connected with vehicle-mounted ECU.In the technical program, the normal condition of Locking Device is lockup state, electromagnet no power, and locking spring stretches, and when Locking Device receives after the movable signal of vehicle-mounted ECU feedback, electromagnet energising, is pulled away from locked groove by dead bolt; When Locking Device receives after the limit signal of vehicle-mounted ECU, electromagnet quits work, and locking spring is pressed into locked groove by dead bolt.
The beneficial effects of the utility model are that the utility model has been realized the spacing and automatic locking being suspended in moving process, makes suspension can not depart from vehicle body, and limits its degree of freedom, guarantees that wheelspan changes the safety of rear vehicle, the possibility that minimizing accident occurs.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure, 1, limiting stopper first; 2, limiting stopper second; 3, pressure sensor; 4, the first locked groove; 5, the second locked groove; 6, Locking Device; 7, locking spring; 8, electromagnet; 9, dead bolt.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model is further explained:
With reference to Fig. 1, a kind of automobile wheel track moves limiting lock locking apparatus, comprise the motor that suspension is moved, also comprise the limiting stopper first 1 being arranged on vehicle body and be arranged on the limiting stopper second 2 on removable suspension, difference setting pressure sensor 3 in limiting stopper first 1 and limiting stopper second 2, between limiting stopper first 1 and vehicle body, be provided with the first locked groove 4, limiting stopper second 2 is provided with the second locked groove 5 with suspension strut, and limiting stopper first 1 is respectively equipped with Locking Device 6 with limiting stopper second 2 upper ends.Pressure sensor 3 is connected with motor.The first locked groove 4 is T font, and the second locked groove 5 is the inverted T-shape matching with the first locked groove 4.Locking Device 6 comprises, locking spring 7, electromagnet 8 and dead bolt 9, and Locking Device 6 is connected with vehicle-mounted ECU.
The normal condition of Locking Device is lockup state, electromagnet no power, and locking spring stretches, and when Locking Device receives after the movable signal of vehicle-mounted ECU feedback, electromagnet energising, is pulled away from locked groove by dead bolt; When Locking Device receives after the limit signal of vehicle-mounted ECU, electromagnet quits work, and locking spring is pressed into locked groove by dead bolt.In suspension moving process, limiting stopper first and the touching of limiting stopper second, pressure sensor is passed to motor by signal, suspension is stopped mobile, motor is passed to vehicle-mounted ECU by signal, and then feeds back to Locking Device, and Locking Device triggers locking, suspension is fixed on vehicle body, thereby realized the spacing and automatic locking being suspended in moving process, made suspension can not depart from vehicle body, and limited its degree of freedom, guarantee that wheelspan changes the safety of rear vehicle, the possibility that minimizing accident occurs.
