Description

Technical Field

[0001] The invention belongs to the technical field of automobile manufacturing, and more specifically, particularly relates to a chassis system with a telescopic wheelbase. Background Art

[0002] The function of the chassis is to support and install the automobile engine and its components and assemblies, forming the overall shape of the automobile, and receiving the power of the engine to make the automobile move and ensure normal driving. It is generally composed of a clutch, transmission, universal joint, main reducer, differential and half-axles, which are assembled uniformly by bolts and snap-on structures.

[0003] Based on the above, the currently commonly used chassis is mainly a unified structure, which does not have the function of adjusting and increasing the spacing when moving. It cannot change the position of the car by adjusting the wheelbase during driving to facilitate driving. It is easy to slip when it rains or in wet places, and it is impossible to try to return to move through the car's own functions.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a chassis system with a retractable wheelbase is provided to achieve a more practical purpose. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a chassis system with a retractable wheelbase to solve the problems mentioned in the above background technology that the currently commonly used chassis is mainly of a unified structure, does not have the function of adjusting and increasing the spacing when moving, cannot change the position of the car by adjusting the wheelbase during driving to facilitate driving, is prone to slipping in rainy days or in wet places, and cannot try to return to move through the car's own functions.

[0006] The purpose and effect of the chassis system with a retractable wheelbase of the present invention are achieved by the following specific technical means:

[0007] A chassis system with a telescopic wheelbase comprises an axle frame, a support block, an inner rod, a mounting frame, an axle frame connecting rod, an axle frame connecting plate, an expansion lever, an outer connecting rod and a hydraulic cylinder; the number of the axle frames is set to four groups, and an axle frame connecting rod is fixedly arranged between two groups of axle frames via a rotating shaft; a mounting frame is integrally arranged on the outer top of each axle frame.

[0008] Furthermore, an inner rod is fixedly arranged on the rear side of the shaft frame by screws; two groups of support blocks are fixedly connected by welding between two groups on the same side of the inner rod; and the support blocks are all square frame structures.

[0009] Furthermore, five groups of through holes are opened on both sides of the axle frame connecting rod; an expansion lever is provided at the outer end of the axle frame connecting rod through a rotating shaft, and two groups of external connecting rods are provided on the outer side of the expansion lever through a rotating shaft; the two groups on the same side of the external connecting rod are fixedly connected by two groups of support blocks provided by welding.

[0010] Furthermore, a through hole is provided in the middle of each of the outer connecting rods, and a hydraulic cylinder is movably provided in the outer connecting rod through a rotating shaft and a gasket.

[0011] Furthermore, the tops of both ends of the double-layer structure of the axle frame are integrally provided with protrusion structures, and the protrusion structures are higher than the height of the rotating shaft of the edge expansion lever; the tops of the two axial groups of protrusion structures are fixed with axle frame connecting plates by welding.

[0012] Furthermore, the rotatable angle of the edge expansion lever is limited to 0-75° by the support block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting the expansion lever, the external connecting rod and the hydraulic cylinder, the chassis is provided with the function of extending and retracting the wheelbase. The external connecting rod can be directly expanded by the hydraulic cylinder, and the position of the inner rod and the axle frame connecting plate can be moved in cooperation with the external connecting rod, and the axle frame can be expanded to both sides to increase the wheelbase. In the process of driving, the position of the car can be changed by adjusting the wheelbase to achieve the effect of facilitating driving. When the car slips and falls, it can try to return and move through its own function, and it has strong applicability.

[0015] By setting the support block, the spacing of the axle frame can be supported and guaranteed to prevent the vehicle body from being deformed. The support block is a frame-type structure, which has low cost, convenient assembly and welding, strong anti-deformation ability, and light weight. In addition, the support block can limit the rotatable angle of the edge expansion lever to assist in ensuring the extended position of the external connecting rod. BRIEF DESCRIPTION OF THE DRAWINGS
