Abstract
The utility model discloses a mechanism capable of achieving front axle rotation and rear axle locking and is applicable to a double-cab passenger car. The mechanism comprises a steering engine (1), a main oil cylinder (2), a centering oil cylinder (3), an energy accumulator (4), a locking switch (5) and a steering drag link (6), wherein the steering engine (1) is connected with the main oil cylinder (2) through an oil pipe, the main oil cylinder (2) is connected with the centering oil cylinder (3) through an oil pipe, the energy accumulator (4) and the locking switch (5) are connected with the pipe between the main oil cylinder (2) and the centering oil cylinder (3), the steering engine (1) is connected with a steering front axle through the steering drag link (6), and a piston rod of the centering oil cylinder (3) is connected with a steering rear axle. After the mechanism capable of achieving front axle steering and rear axle locking is installed on the double-cab passenger car, the whole-car load increase caused by excessive devices of the double-cab passenger car can be reduced, and a non-interference mode of front and rear axle steering operation systems of the double-cab passenger car is achieved when drivers change cabs for operation.
Description
Technical field
The utility model relates to a kind of propons and rotates, and the mechanism of back axle locking belongs to double-cab passenger vehicle power transmission technical field.
Background technology
Current, so-called double end cab structure exists only in subway, the railway traffic transportation, this is because subway and railway all use track as the operation accessory appliances of transportation means, restricted the commutation operation mode of institute's vehicle in use within the specific limits, such as the existing just widely used motor train unit of China.But motor train unit are in view of connection mode flexibly between each compartment, and the double end operator's compartment has been arranged independently the safety of operation system driver behavior of being correlated with respectively.Yet, double end operator's compartment passenger vehicle can't realize that as an one-piece construction operator's compartment is equipped with the operation scheme of an independent operating system, bears a heavy burden because this not only can increase car load, strengthen wire harness and arrange difficulty, and this has also caused certain influence to car load operation performance simultaneously.
Summary of the invention
The purpose of this utility model in order to solve rear-axle steering mutually noninterfere before the double end operator's compartment passenger vehicle, guarantees the problem of the normal operation of double end operator's compartment passenger vehicle, and the utility model disclose a kind of propons rotation, the mechanism of back axle locking.
The technical solution of the utility model is, the utility model propons rotates, and the mechanism of back axle locking is made up of steering box 1, master cylinder 2, centering oil cylinder 3, accumulator 4, locking switch 5 and steering drag link 6.Steering box links to each other with master cylinder by oil pipe, and master cylinder links to each other with the centering oil cylinder by oil pipe; Pipeline at master cylinder and centering oil cylinder is connected with accumulator and locking switch; Steering box turns to propons by the steering drag link connection; The connection of centering oil cylinder piston bar turns to back axle.
Principle of work of the present utility model is, as shown in Figure 1, steering box 1 utilizes steering drag link 6 with turning to propons to be connected, and makes steering box 1 when obtaining steering power, because the draw of middle straight pull bar, drives and turns to propons to turn to operation.Accumulator 4 is to improve propons and turns to draw power to rear-axle steering.5 for turning to the locking switch, and when 1 steering box motion drive propons turned to, 5 by induction, carries out the locking to rear-axle steering, reached and realized that propons turns to, the purpose of back axle locking, the mutually noninterfere of assurance dual rotation system.2 for master cylinder, 3 effect provides oil circuit to guarantee with regard to steering power respectively for the centering oil cylinder.
The beneficial effects of the utility model are, install at double end operator's compartment passenger vehicle that propons turns to, after the structure of back axle locking, can reduce double end operator's compartment passenger vehicle increases because too much equipping the car load heavy burden that brings, realize the mutually noninterfere pattern of rear-axle steering work system before double end operator's compartment passenger vehicle is when chaufeur is changed bridge operation, solve a double end operator's compartment passenger vehicle reversing switch operation difficult problem, possess good operation performance for car load and give security.
The utility model is applicable to the double-cab passenger vehicle.

The specific embodiment
The specific embodiment of the present utility model is implemented at the double-cab passenger vehicle.
As shown in Figure 1, the present embodiment propons rotates, and the mechanism of back axle locking is made up of steering box 1, master cylinder 2, centering oil cylinder 3, accumulator 4, locking switch 5 and steering drag link 6.Steering box 1 links to each other with master cylinder 2 by oil pipe, and master cylinder 2 links to each other with centering oil cylinder 3 by oil pipe; Pipeline at master cylinder 2 and centering oil cylinder 3 is connected with accumulator 4 and locking switch 5; Steering box 1 turns to propons by steering drag link 6 connections; The connection of centering oil cylinder 3 piston rods turns to back axle.
Present embodiment in use, steering box 1 utilizes steering drag link 6 with turning to propons to be connected, and makes steering box 1 when obtaining steering power, because the draw of middle straight pull bar, drives and turns to propons to turn to operation.Accumulator 4 is to improve propons and turns to draw power to rear-axle steering.5 for turning to the locking switch, and when 1 steering box motion drive propons turned to, 5 by induction, carries out the locking to rear-axle steering, reached and realized that propons turns to, the purpose of back axle locking, the mutually noninterfere of assurance dual rotation system.2 for master cylinder, 3 effect provides oil circuit to guarantee with regard to steering power respectively for the centering oil cylinder.
