Abstract
The invention discloses a swing arm type obstacle crossing chassis which comprises a vehicle body, a swing arm driving mechanism and front 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 slide block. The rear wheel of the swing arm type obstacle crossing driving chassis is hinged to a first auxiliary driving arm connected with a front wheel through a second auxiliary driving arm, the middle position of the first auxiliary driving arm is connected with a first main driving arm through an adjusting slider, the first main driving arm is connected with a first driving hydraulic cylinder and a second driving hydraulic cylinder respectively, a hydraulic rod of the first driving hydraulic cylinder stretches and retracts to drive the first auxiliary driving arm to rise and fall around a hinge point, a hydraulic rod of the second driving hydraulic cylinder stretches and retracts to drive the second auxiliary driving arm to swing, and the two control motions can effectively adjust the rising and falling of the two wheels, so that the height of the center of a vehicle body is controlled, the chassis is ensured to stably cross obstacles, and the effect of relieving road surface impact is. Swing arm formula hinders chassis primary structure more includes: the hydraulic control mechanism mainly 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 slide block (8) and a vehicle body (9).
Description
Technical Field
The invention designs a swing arm type obstacle crossing chassis which is mainly used for harvesting on rugged forest lands and the like, has good trafficability through various obstacles, and can adjust the gravity center of a vehicle body during obstacle crossing so as to keep the stability of no rollover.
Background
At present, when forestry equipment works on irregular forest land and inclined slope-shaped land, the gravity center is not adjusted timely, the stability is poor, and the forestry equipment is easy to tip over.
Disclosure of Invention
The invention provides a swing arm type obstacle crossing mechanism which can adjust the position of the gravity center of a vehicle body through actions of lifting and putting down wheels and the like when crossing obstacles and enhance the smoothness and trafficability of the whole vehicle. The design can be applied to various woodland operation chassis. The purpose of the invention is realized by the following technical scheme:
the invention relates to a swing arm type obstacle crossing chassis which comprises a vehicle body, a swing arm driving mechanism and front and rear wheels, wherein the swing arm driving mechanism comprises a main driving arm, an auxiliary driving arm, a driving hydraulic cylinder and an adjusting slide block. The centers of the front wheel and the rear wheel are respectively connected with the tail ends of the two auxiliary driving arms, and the head ends of the swing arm driving mechanisms are hinged on the vehicle body. When the wheels encounter obstacles, the wheels are lifted up by adjusting the corresponding driving arms in the swing arm driving mechanism, so as to achieve the purpose of obstacle crossing.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention, which mainly comprises a main driving arm 1, a main driving arm 2, auxiliary driving arms I and 3, a rear wheel 4, auxiliary driving arms II and 5, a rear wheel 6, driving hydraulic cylinders II and 7, driving hydraulic cylinders I and 8, an adjusting slide block 9, and a vehicle body
FIG. 2 is a diagram of the front wheel obstacle surmounting of the chassis
Detailed Description
The practice of the present invention will now be described in further detail with reference to the accompanying drawings in which:
the invention discloses a lifting type special-shaped chain grass dividing mechanism which is characterized in that a swing arm type obstacle crossing chassis comprises a vehicle body, a swing arm driving mechanism and front 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 slide block.
The control of the swing arm type obstacle crossing driving mechanism is mainly completed by driving a hydraulic cylinder to push a plane connecting rod mechanism to move, and the specific principle is as follows: the rear wheel is hinged to a first auxiliary driving arm connected with the front wheel through a second auxiliary driving arm, the middle position of the first auxiliary driving arm is connected with the first main driving arm through an adjusting slider, the first main driving arm is respectively connected with a first driving hydraulic cylinder and a second driving hydraulic cylinder, the first auxiliary driving arm can be driven to rise and fall around a hinge point by stretching of a hydraulic rod of the first driving hydraulic cylinder, the second auxiliary driving arm can be driven to swing by stretching of a hydraulic rod of the second driving hydraulic cylinder, the two control motions can effectively adjust the rising and falling of the two wheels, the height of the center of the vehicle body is controlled, the chassis is guaranteed to stably cross obstacles, and the effect of relieving road surface impact is achieved.
