Swing arm type obstacle crossing chassis

Abstract

The invention discloses a swing arm type obstacle crossing chassis, which comprises a vehicle body, a swing arm driving mechanism, front wheels and rear wheels. The swing arm type driving mechanism comprises a main driving arm, a first auxiliary driving arm, a second auxiliary driving arm, a first driving hydraulic cylinder, a second driving hydraulic cylinder and an adjusting sliding block. Rearwheels of the swing arm type obstacle crossing driving chassis are hinged to a first auxiliary driving arm connected with the front wheel through the second auxiliary driving arm. The middle positionof the first auxiliary driving arm is connected with the first main driving arm through the adjusting sliding block. The first driving hydraulic cylinder and the second driving hydraulic cylinder arerespectively connected to the main driving arm; a hydraulic rod of the first driving hydraulic cylinder stretches out and draws back to drive the first auxiliary driving arm to rise and fall around ahinge point; a hydraulic rod of the second driving hydraulic cylinder stretches out and draws back to drive the second auxiliary driving arm to swing, the two control motions can effectively adjust rise and fall of the two wheels, and therefore the height of the center of the vehicle body is controlled, the chassis is ensured to stably cross obstacles, and the effect of relieving road impact is achieved. The swing arm type obstacle crossing chassis mainly structurally comprises a main driving arm (1), a first auxiliary driving arm (2), a rear wheel (3), a second auxiliary driving arm (4), a rear wheel (5), a second driving hydraulic cylinder (6), a first driving hydraulic cylinder (7), an adjusting sliding block (8) and a vehicle body (9).

Description

technical field [0001] The present invention designs a swing-arm type obstacle-surmounting chassis, which is mainly used for logging in rugged woodlands, etc. It has good passability through various obstacles, and can adjust the center of gravity of the vehicle body to maintain the stability of not tipping over obstacles. . Background technique [0002] At present, when forestry equipment operates on irregular forest ground or slope-shaped ground, the center of gravity cannot be adjusted in time, the stability is poor, and it is easy to tip over. Contents of the invention [0003] The invention provides a swing-arm type obstacle-climbing mechanism that adjusts the position of the center of gravity of the vehicle body and enhances the ride comfort and passability of the entire vehicle through actions such as raising and lowering the wheels when crossing obstacles. The design can be applied to various woodland operation chassis. The purpose of the present invention is achi...
