Abstract
The utility model discloses a rear suspension system of a wide-body dumper. The rear suspension system of the wide-body dumper is characterized by comprising a frame (1), an intermediate axle (2), a rubber spring (3), a front pull rod (4), a front thrust arm (5), a first hinge pin (6), a balance beam (7), a balance shaft (8), a bearing (9), a rear thrust arm (10), a rear axle (11), a rear pull rod (12), a hydro-pneumatic spring (13), a second hinge pin (14) and a third hinge pin (15). The intermediate axle (2) rotates around the first hinge pin (6) through the front thrust arm (5), the rear axle (11) rotates around the third hinge pin (15) through the rear thrust arm (10), the balance beam (7) rotates around the balance shaft (8), one end of the balance beam (7) is connected with the intermediate axle (2), and the other end of the balance beam (7) is connected with the rear axle (11) through the hydro-pneumatic spring (13). When the rear suspension system composed of the rubber spring and the hydro-pneumatic spring is applied to the wide-body dumper, the problems that when a rubber spring is independently used, rigidity is high, and when a hydro-pneumatic spring is independently used, a rear axle cannot be easily balanced are solved, and the failure rate of a rear suspension is effectively reduced.
Description
Technical field:
The utility model relates to wide dumper technical field, is a kind of wide dumper rear suspension system specifically, is specially adapted to 6 × 4 wide dumpers.
Technical background:
The rear-mounted of wide dumper all adopts steel spring structure at present, is subject to the restriction of steel spring load-carrying capacity, and its tonnage general control is 60 tons of left and right, and the fault rate of steel spring is higher.What 6 × 6 radial type quarry tippers on market adopted is rubber spring structure, and what 4 × 2 quarry tippers adopted is hydro-pneumatic spring structure.Be subject to wide dumper structural limitations, be difficult to the equilibrium problem of back axle in solving, and adopt rubber spring structure on 6 × 4 wide dumpers while mating hydro-pneumatic spring rear suspension system, its rigidity is larger, larger on the impact of car load ride comfort, reduces vehicle riding comfort.
Utility model content:
The purpose of this utility model is the deficiency that overcomes prior art, and a kind of wide dumper rear suspension system is provided, and mainly solves in the limited and fault rate of wide dumper upper steel plate spring load high and rubber spring and hydro-pneumatic spring impact the problems such as back axle balance.
The technical solution of the utility model is: a kind of wide dumper rear suspension system, and its special character is that it is made up of vehicle frame, jackshaft, rubber spring, front tension bar, forward thrust arm, the first bearing pin, equalizing bar, balance shaft, bearing, the pusher arm of force, back axle, back stay, hydro-pneumatic spring, the second bearing pin, the 3rd bearing pin; Described jackshaft and forward thrust arm one end are rigidly connected, and the forward thrust arm other end is connected with vehicle frame by the first bearing pin, and jackshaft is connected with vehicle frame by front tension bar, and jackshaft rotates around the first bearing pin; Back axle and pusher arm of force one end are rigidly connected, and the pusher arm of force other end is connected with vehicle frame by the 3rd bearing pin, and back axle is connected with vehicle frame by back stay, and back axle rotates around the 3rd bearing pin; Balance shaft and vehicle frame are rigidly connected, and equalizing bar is connected with balance shaft by bearing, and equalizing bar rotates around balance shaft, and equalizing bar one end is connected with jackshaft by rubber spring, and the other end connects hydro-pneumatic spring by the second bearing pin, and hydro-pneumatic spring is connected with back axle.
Compared with the prior art a kind of wide dumper rear suspension system described in the utility model has following good effect: 1, cancelled steel spring, can effectively reduce rear-mounted fault rate; 2, the rear suspension system of application of rubber spring and hydro-pneumatic spring composition on wide dumper, while having overcome independent use rubber spring rigidity large and while using hydro-pneumatic spring separately in back axle be difficult to the difficult point of balance.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
Drawing explanation:
1 vehicle frame, 2 jackshafts, 3 rubber springs, 4 front tension bars, 5 forward thrust arms, 6 first bearing pins, 7 equalizing bars, 8 balance shafts, 9 bearings, the 10 pusher arm of forces, 11 back axles, 12 back stays, 13 hydro-pneumatic springs, 14 second bearing pins, 15 the 3rd bearing pins.
The specific embodiment:
For Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model in detail; Illustrated embodiment is only for explaining the utility model, not for limiting scope of the present utility model.
Embodiment 1, referring to Fig. 1,2, by designing requirement, jackshaft 2 and forward thrust arm 5 one end are rigidly connected, forward thrust arm 5 other ends are connected with vehicle frame 1 by the first bearing pin 6, and jackshaft 2 is connected with vehicle frame 1 by front tension bar 4, jackshaft 2 is rotated around the first bearing pin 6; Back axle 11 and the pusher arm of force 10 are rigidly connected, and the pusher arm of force 10 one end are connected with vehicle frame 1 by the 3rd bearing pin 15, and back axle 11 is connected with vehicle frame 1 by back stay 12, and back axle 11 is rotated around the 3rd bearing pin 15; Balance shaft 8 and vehicle frame 1 are rigidly connected, and equalizing bar 7 is connected with balance shaft 8 by bearing 9, and equalizing bar 7 rotates around balance shaft 8; Equalizing bar 7 one end are connected with jackshaft 2 by rubber spring 3, and the other end connects hydro-pneumatic spring 13 by the second bearing pin 14, and hydro-pneumatic spring 13 is connected with back axle 11.
A kind of wide dumper rear suspension system described in the utility model, it is a kind of wide dumper rear suspension system that adopts rubber spring and hydro-pneumatic spring, because the rigidity of the rubber spring in suspension is large, the rigidity of hydro-pneumatic spring is little, so when work, equalizing bar rotates around balance shaft, and rubber spring mainly plays carrying effect, and hydro-pneumatic spring plays cushioning effect.
