Abstract

The invention discloses a wheelbase adjusting device for a vehicle, which comprises: a suspension mounting seat installed on the cross arm of the vehicle; a wheelbase changing driver installed on the vehicle frame and used to push the suspension cross arm and the wheel Move relative to the frame together; the guide wheel assembly is installed on both sides of the suspension mounting seat, and rolls in contact with the upper surface of the frame longitudinal beam when the suspension cross arm moves; the locking mechanism assembly is installed on the suspension mounting seat , when the suspension cross-arm is in a non-moving state, the suspension mounting seat and the longitudinal beam of the vehicle are locked. The invention has the advantages of simple structure, and the vehicle wheelbase can be adjusted according to road conditions.

Description

technical field [0001] The invention mainly relates to the field of wheeled vehicle chassis, in particular to a wheelbase adjusting device suitable for vehicles. Background technique [0002] The wheeled chassis has low driving resistance, low noise, good steering performance and high mobility, so it is widely used in various high mobility vehicles, including various types of automobiles and special vehicles. The performance of the wheeled chassis will directly affect the passability and driving reliability of the vehicle. [0003] At present, the wheeled running mechanisms used in automobiles and special vehicles are mainly distributed on the left and right sides of the car body. Automobiles mainly have four wheels, and special vehicles mostly have six wheels or more. Every two wheels are a group, connected by the axle, the axle is connected with the frame (or body) by the suspension, the wheels, the axle, the suspension and the frame (body) constitute the chassis of the v...
