Embodiment Construction
[0014] The present invention will be described in detail below with the best embodiment.
[0015] Such as Figure 1-4 As shown, a double-section tracked vehicle suspension truss structure includes a shield assembly 3, a left suspension bracket 4 and a right suspension bracket 5. The left inclined steel plate and the bottom are the overall structure formed by welding horizontal steel plates. The right suspension bracket 5 and the left suspension bracket 4 have the same structure of left and right symmetrical switches; Fixing holes, the two fixing holes are up and down structure, and the two cylinders are welded by two tangential steel plates arranged in front and back to form an integrated structure; the fixing hole assembly 2 arranged up and down on the right side is symmetrical with the fixing hole assembly 1 arranged up and down on the left side The shape is the same; the right suspension brackets 5 and 6 have holes matching the shape of the left and right vertically arrang...

The invention discloses a double-section crawler suspension truss structure, and relates to the technical field of engineering vehicles, in particular to a crawler suspension truss structure. The structure comprises a shield assembly, a left side suspension bracket and a right side suspension bracket, the left side vertically-arranged fixing hole assembly comprises fixing holes formed by welding two cylindrical steel plates, and the two fixing holes are of a vertical structure; a circular through hole is formed in the center of the shield assembly vertically; two ends of the shield assembly are welded with the left suspension bracket and the right suspension bracket; the inner ends of the left vertically-arranged fixing hole assembly and the right vertically-arranged fixing hole assembly are welded to the left end and the right end of the shield assembly correspondingly. The axes of through holes vertically formed in the left vertically-arranged fixing hole assembly, the right vertically-arranged fixing hole assembly and the shield assembly are the same. The problems that a center fixing hole of an existing crawler suspension truss torsion bar spring is of a geometric structure arranged front and back, and consequently the installation space and the damping performance of a crawler suspension truss structure are insufficient are solved.
Description
technical field [0001] The invention relates to the technical field of engineering vehicles, in particular to a crawler vehicle suspension truss knot. Background technique [0002] The tracked vehicle action device mechanism uses the car body as the support body of the action system, and axially fixes the driving wheel, suspension device, induction wheel, track tensioning device and supporting pulley to the car body, and forms it through the track. Closed loop, without the body action system, the driving function of the vehicle cannot be satisfied. The vibration damping of the mobile system suspension adopts torsion bar springs, which are dimensioned throughout the entire car body. The above-mentioned structure occupies a large space of the vehicle body, so that the vehicle body occupies a large proportion in the weight of the vehicle. For this reason, the applicant invented a full-rubber independent walking system for a two-section crawler vehicle (patent application numb...
