Description

Distance adjustable axle

Technical field

The utility model relates to a kind of vehicle bridge.

Background technology

Present self-propelled vehicle or non-power-driven vehicle all are the vehicle bridge methods of a kind of fixing vehicle wheel position of employing, and its chassis is also fixed, but for very inconvenience of agricultural production.Because the sowing of crops is to require to determine certain spacing or line-spacing according to self growth, and growing height also is uneven.So, be applied to machinery or vehicle among the agricultural production at present, can only be equipped with big four-wheel or little four-wheel motor vehicles and machines reach required production requirement by accent.Yet not only energy dissipation is big, and production efficiency and economic benefit are also very low.

Summary of the invention

For overcoming above-mentioned defective, the purpose of this utility model provides a kind of Distance adjustable axle, reaches according to the difference of the line-spacings of crops or spacing and adjusts the wheelspan of car and the purpose of chassis height neatly.

For achieving the above object, the technical solution of the utility model is as follows: a kind of Distance adjustable axle, it is characterized in that: it comprises main beam, secondary crossbeam, main bridge sleeve pipe, retractile bridge, the roll adjustment screw mandrel, the roll adjustment strut, the design of main beam middle part has screw hole, the middle part design of secondary crossbeam has roll adjustment screw mandrel position, the two ends of roll adjustment screw mandrel have positioning table and locator card respectively, roll adjustment strut and strut cover form integral body by screw thread fit, its two ends one end has the strut socket that connects retractile bridge, the other end has wheel that wheel seat is installed, main bridge sleeve pipe is two hollow steel pipes and connects into rectangle with main beam respectively, retractile bridge is divided into two groups, every group has two steel pipes to connect into integral body by the two ends of secondary crossbeam, the opposite end head of two groups of retractile bridges extends in the pipe from the two ends of main bridge sleeve pipe respectively, the other end is connected with two strut sockets, respectively there is a roll adjustment screw mandrel at the two ends of whole bridge, and an end of roll adjustment screw mandrel and retractile bridge pass the screw hole at main beam middle part synchronously, and the other end is connected with the roll adjustment screw mandrel position at secondary crossbeam middle part.

Strut socket described in the utility model is wheel support and connection positions; The strut cover is a strut roll adjustment seat, in screw thread is arranged; Main bridge sleeve pipe is the flexible seat of main vehicle bridge, retractile bridge; The roll adjustment strut is used for support wheel, and an end has outside thread and strut cover screw-internal thread fit, and an end is the wheel installation position; Retractile bridge one end is a wheel assembly mechanism, and the other end extends to form in the main bridge sleeve pipe to be stretched and cooperating of contracting; Wheel seat is the wheel installation position; Main beam is that main bridge sleeve pipe forms the single-piece connection, also is the working position of roll adjustment screw mandrel; Screw hole is the screw thread fit seat of roll adjustment screw mandrel; The roll adjustment screw mandrel is the foundation brakes that retractile bridge is stretched and contracted; Positioning table is the location of maximum roll adjustment amplitude; Secondary crossbeam is that retractile bridge forms the single-piece connection, also is that retractile bridge is connected with the synchronous of roll adjustment screw mandrel; Roll adjustment screw mandrel position is that retractile bridge is the Brake Block of roll adjustment screw mandrel; Tie down screw is being connected and fixed of retractile bridge and strut socket; Locator card is for pinning being connected of roll adjustment screw mandrel and secondary crossbeam; The braking head is the instrument retarder location.Main bridge sleeve pipe is assemblied in institute joins on the vehicle bridge position and on the wheel seat wheel is installed, just can start working.Can use spanner rolling brake head as required, at this moment the roll adjustment screw mandrel is just pulled out retractile bridge or indentation by screw hole, just reaches to transfer wide or transfer narrow purpose.Rotation strut cover or roll adjustment strut just reach heightens or transfers short purpose.

The utility model has adopted the technical scheme of economy, simple structure, and ownership actuation mechanism all is to be finished by manual operation.Combine the ease of use in the agricultural production fully, simple in structure, economical and practical, improved the Occupation coefficient of field machine significantly, accelerated the process of agriculture round Realization mechanization.Its stop mechanism has particularly reasonably adopted the principle of mechanics lever, need not the mechanical power transmission, just can reach the purpose of any adjustment with manpower, thereby strengthen its energy-saving and cost-reducing property, makes production efficiency and economic benefit obtain increasing substantially.It can be decided to drive and travel, and also can do secondary the driving and travel, or drag the case back axle.Both can be assemblied on the three-wheel vehicle, also can be assemblied on the four-wheeled.Its chassis and wheel spacing adjusting range are big, can adapt to the requirement of various crops production operations.
