Abstract
The utility model provides an automobile with a lifting steering bridge. The automobile is characterized in that one end of a steel plate spring of a steering bridge assembly is hinged on a steel plate spring bracket on the lower part of a vertical beam of the frame of the automobile, the other end is connected with a lifting air chamber push rod of a lifting air chamber arranged on the vertical beam of the frame of the automobile; by the extension or withdrawal of the lifting air chamber push rod, the steel plate spring is driven to swing, and the lifting or the drop of the steering bridge is realized; a steering knuckle arm on the steering bridge assembly is connected with a vertical arm of a redirector of a director redirector, then the director can be used to control the turning of the steering bridge. The automobile of the utility model has the advantages that the lifting of the steering bridge is realized by lifting the suspension of the traditional steel plate spring, the rationality of the bearing of the automobile is improved, the contact abrasion of the tyres to the ground during the zero-load running of the automobile is reduced, the oil consumption is saved, and the usage cost is lowered; during the heavy-load running of the automobile, the bearing capacity of the automobile is improved; when the automobile turns with heavy load, the turning of the steering bridge and the front bridge turn simultaneously in linkage, the side abrasion of the tyres is reduced, and the flexibility of the running of the automobile is improved.
Description
Technical field
The utility model relates to a kind of automobile that promotes the steeraxle device.
Background technology
Existing 6 * 2,8 * 2,8 * 4 automobiles all are to increase following steering axle or the non-vehicle bridge that turns on 4 * 2,6 * 4 automobile bases, all can not promote, during the automobile deadhead operation, tire and ground-surface contact friction meeting reduce the service life of tire, increase the car opertion cost, and the automobile fuel consumption height.The pontoon bridge of existing 10 * 4 automobiles adopts the gasbag seat cushion to hang, and the lifting of this pontoon bridge is entirely by air bag, so this system complex, the manufacturing cost height, and also the service life of air bag is short.
Summary of the invention
The purpose of this utility model just provides a kind of between the bridge of the front and back of automobile or increase the steeraxle of on-propelled after the back axle, thereby improve the load-carrying capacity of automobile, alleviate deadweight, reduce manufacturing cost, improve the reasonableness of running car, reduce the automobile of the lifting steeraxle device of use cost.
Solution of the present utility model is such: an end of the steel spring of steeraxle assembly is hinged on the spring carrier of chassis side rail bottom, the other end is to be connected with the lifting swing arm that is installed in chassis side rail, utilization promotes stretching out of air chamber push rod or bounces back, the swing of drive steel spring realizes lifting or whereabouts to steeraxle; Above-mentioned steeraxle can be installed between the front and back bridge of automobile or after the back axle; Single axle can be adopted, also multiaxial type can be adopted.
Track arm on the steeraxle assembly is connected with the deflector plumbing arm of direction machine deflector, just can utilize the direction machine that steeraxle is turned to control.
The utility model has the advantages that by promoting traditional BF and realize the lifting of steeraxle that improve the reasonableness of automobile carrying, oil consumption is saved in the tire contact abrasion of face over the ground when reducing the automobile deadhead operation, reduces use cost; When the automobile heavy duty is travelled, improve the load-carrying capacity of automobile, during automobile heavy duty turning driving, turn to and the propons synchronous interaction of steeraxle turn to, and reduce the eccentric wear of tire, improve the manoevreability of running car.
