Embodiment 1

[0030] Such as Figure 1 to Figure 3 A light-weight and high-strength balance bridge is shown, including two connecting brackets 1, a balance shaft 10 that fits loosely with the connecting bracket 1, and an integral leaf spring seat 2 installed on the balancing shaft 10. The connecting bracket 1 is made of high-strength Made of castings, the integral leaf spring seat 2 is connected to the leaf spring through U-shaped bolts; the upper part of the connecting bracket 1 is connected to the thrust rod, and the upper ends of the two connecting brackets 1 are fixedly connected to the relative position of the bolt mounting plate 11, and the bolt mounting plate 11 A plurality of bolt holes are provided on the surface of the bolt mounting plate 11, and connecting bolts 4 are penetrated in the bolt holes of the bolt mounting plate 11, and the two ends of the connecting bolts 4 extend to the outer surfaces of the two connecting plates 3 and are screwed with nuts, and the connecting bolts 4...

Embodiment 2

[0034] Such as Figure 4 A lightweight high-strength balance bridge shown, the rest is the same as in Embodiment 1, the difference is that: the middle parts of the two connecting plates 3 are provided with protrusions, and both ends of the protrusions are excessively connected to the slope of the connecting plates Connection, which can increase the bending strength of the connecting plate.

Abstract

The invention provides a light weight and high strength balance bridge. The light weight and high strength balance bridge comprises two connecting brackets, balance shafts in clearance fit with the connecting brackets and integral type plate spring seats mounted on the balance shafts. Bolt mounting plates are fixedly connected to the corresponding positions of the upper ends of the two connectingbrackets, a plurality bolt holes are formed in the surfaces of the bolt mounting plates, connecting plates are arranged on the two sides of the bolt mounting plates, the two connecting plates are straight plates with a same size, and bolt holes matched with the bolt mounting plates are formed in the two ends of the two connecting plates. Under a premise of not changing the loading capacity of a whole vehicle and the whole strength of parts, oil consumption of the whole vehicle is reduced, a detachable structure and maintenance-free bearings are convenient to use and maintain, the using cost islower, the economic benefit of the whole vehicle using is improved, and the problems that an existing driving bridge balanced suspension system is heavier and maintenance and replacement are inconvenient are solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a lightweight and high-strength balance bridge. Background technique [0002] At present, the suspension of existing engineering vehicles is mainly a leaf spring suspension, and the core component of the leaf spring suspension is a balance bridge. [0003] The drive axle balance suspension system is a suspension system composed of two drive axles, thrust rods, leaf springs and other components with the balance shaft as the main component, and is widely used. [0004] However, the existing drive axle balance suspension system is heavy. Since the middle connecting shaft and the brackets on both sides are interference fit, they cannot be disassembled after assembly. If one side bracket is damaged during use, the entire assembly must be replaced, resulting in product cost and use cost. It is quite high. In addition, due to the heavy weight of the tires, the tires wear faster and ...
