Description

Cab rear overhang shock attenuation latch hook support assembly

Technical Field

The utility model belongs to the technical field of commercial driver's cabin rear suspension and specifically relates to a driver's cabin rear suspension shock attenuation latch hook support assembly.

Background

The rear suspension of the cab is positioned at the rear part of the cab, is used for connecting the cab and the chassis, is one of the components of a cab suspension system, and the quality and the performance of the rear suspension of the cab directly influence the running smoothness and the running safety of the truck. The rear suspension of the similar cab in the current market is mainly divided into the following three types according to the damping structure form: 1. the combined structure of the cylinder type shock absorber and the compression spring comprises the following components: patent application No. 2009200791820. 2. Rubber shock absorber adds crossbeam assembly structure. 3. Rubber bumper shock absorber structure. The first suspension chassis has the advantages of large space utilization rate, complex processing technology, high manufacturing cost, large weight and good damping effect. The second suspension has poor damping effect, large chassis space utilization rate, large weight and moderate cost. The third suspension has poor damping effect, light weight, low cost and low chassis space occupancy rate. The suspension has the balance of the relation that the manufacturing cost, the structure is tight and short, the shock absorption is comfortable, and the weight is not reduced.

Disclosure of Invention

To the technical problem, the utility model provides a driver's cabin rear overhang shock attenuation latch hook support assembly makes its advantage of taking into account four aspects of compact structure, better shock attenuation effect, ride comfort and lower manufacturing cost.

In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a driver's cabin rear overhang shock attenuation latch hook support assembly, includes left suspension, right suspension, its characterized in that: the left suspension and the right suspension have the same structure and consist of a latch hook support and a floating bracket fixed on the top end of the latch hook support; the floating type bracket comprises a guide pillar, and a bracket, a beam connecting frame, a shock pad, an upper spring pad, a spring, a lower spring pad and a connecting seat which are sequentially arranged on the guide pillar from top to bottom, wherein locking nuts are arranged at two ends of the guide pillar; the beam connecting frames in the left suspension device and the right suspension device are connected through a beam.

The technical scheme is further limited, the lock hook support is provided with a mounting plate, and the mounting plate can be connected with the airfoil surface of the frame, so that the structural rigidity is increased.

Has the advantages that: the damping module in the utility model is composed of a damping pad and a spring, the damping pad and the spring are arranged coaxially, and the adjustment of the stroke and the rigidity of the damping module under different working conditions can be realized by rotating the locking nut on the guide pillar; meanwhile, the cross beam structure is added, so that the side-tipping stability is improved; the utility model has the advantages of compact structure, good comfort, obvious lightweight effect and low production cost.
